Harry had been dealing with odd things happening to his body since his second year. First there was the almost-invisible belt of scales on his lower belly that stopped right above his cock. Then came sore gums that hid fangs right behind his eye teeth. They would pop out if he bit into something thick hard enough, so he was very careful to choose only soft pieces of meat at dinner. Shortly after that came the venom that the fangs excreted if the roof of his mouth around the fangs was pressed. And in fourth year, his eyes would shift into slits for him to see in the dark.

All of those things were fairly easy to hide, but in fifth year while writing with the blood quill, he started tasting things in the air. There was at first the taste of blood, and he thought that was just exhaustion. However the sense got stronger until he could taste emotions as well as foods and such. The taste of perfume made him dislike being around the fairer sex, so when Cho asked him out, he declined just to get away from the nauseating and bitter taste of her scent.

It drove Harry nuts to not know what was happened. He poured over texts to try to figure it out when Hermione wasn't in the library to see what he was researching, however those times were rare. He finally had to conclude he was a were-snake during his fourth year since it made the most amount of sense - even though the moon cycled did nothing to him - and that he must be the first of his kind because he was the only known survivor of a basilisk bite in history.

However during the summer after fifth year, the biggest change began to happen. The scales on his belly started expanding down his legs, and they even started covering his cock. Using the bathroom was done in a sitting position, and it could get very messy. Then, on the night of his sixteenth birthday just as he was wishing happy birthday to himself, his legs began to elongate. He barely held in a yell of shock as he thrashed his legs to kick the blanket off, but his legs touched each other and sealed together and he could only watch in horror as they turned into one very long snake tail.

Harry laid there stunned while he stared at the jewel-like scales. They were bright green like his eyes were, but along the edges and down the back were thin stripes of black. The belly scales were still pale and the same color as his skin, but they were as hard as his toenails and trying to lift one up caused the same kind of pain though they were a little more flexible under the skin.

"Bloody hell," he groaned in disbelief, then he looked out the window. A quarter moon. And his upper half was quite human like a centaur, though he knew he needed to check himself in a mirror to see.

Thankfully moving in his new body only meant learning how to balance since his tail knew how to move forward. He likened it to extending an arm to catch something. You just paid attention to where it was going to land and made sure your hand was in place to catch, and the body automatically moved all the muscles in anticipation of what was needed. It was only when he tried to focus on said muscles that things would get awkward - that and the balance needed to hold his upper half up.

The first thing Harry did when he wobbled his way off the bed was to extend himself out to try to get an estimate on the length of his tail. It nearly stretched from wall to wall, so he guessed it was about ten feet long starting at the belly. He circled the room a few times to get a better feel for how to move around and balance himself, then he went to the bedroom door, opened it, and peeked out into the dark hall.

There was nobody out and he could hear the snores of his uncle, so he thought it safe to dart out. He nearly slammed himself against the bathroom door since his new body could move exceptionally fast, but he managed to catch himself on the door frame while he brought himself to a stop.

Harry more carefully opened the bathroom door then slithered inside - his tail too long to allow him to close the door. He didn't need the lights on, but he did flick the switch so he could catch any details he might otherwise have missed. Then he put his hands on the edge of the sink, and leaned in close to the mirror.

There was a pale smattering of scales across his brows and turning on the lights didn't take away the slitted pupils like it normally would. A quick grin told him his fangs were still tucked away, then he grabbed the hem of his shirt and pulled it over his head so he could look at his chest. 

Where there would normally be chest hair was more belly scales. They went down his belly like a treasure line until they merged with the top of his tail. He nervously licked his lips a couple times, then he started rubbing his way down to where his pelvis once was to search for where his cock might have gone. It was another foot or so down from where it should have been, nearly at the floor, and he had to twist and turn his tail until his weight was on his 'hip' so he could reach the spot and slide a finger under the scales.

As soon as his finger slipped inside the slit, Harry gasped since it felt weird. Sensitive. Invasive. Slimy and moist. Hot. And then his finger brushed the tip of his cock and he flinched because he had not been expecting it.

Then Harry relaxed since if it still existed, then all he needed to do was figure out how to let it out so he could finally take a proper piss again.

Harry turned off the lights and retreated back into his room. He noticed then that the boxers he had been wearing were torn to shreds from his changed, so he gathered up the scraps and stuffed them into the trash bin that he usually used to dispose of Hedwig's cage lining. After that he slithered back up onto the bed, then he found a new position that allowed him to lay down and feel around inside of the slit.

It took about half an hour of experimentation for his cock to finally move out, however to Harry's shock, two appendages slid out. The first one looked like his regular cock, though it was thicker and longer. The second was smoother, and when he pulled on it to check the tip, he saw the hole for the slit was different. He carefully toyed with it with his finger, and he found that it easily slid in. The inside of his new, second cock was tight and hot, and Harry quietly moaned as he took his actual cock in hand and began to stroke it while he finger fucked the other one.

Never had masturbating felt so good, and when he came, his tail was writhing and curling with pleasure. Better yet, he didn't feel over sensitive so he continued to stroke with his own come acting like lube. That was when he stopped finger fucking and started stroking the other one, and the pleasure doubled. Harry could barely keep his moans to silent gasps as he thrust up into both of his hands, and then he felt the base of his new cock begin to bulge.

That was definitely new enough to snap him out of his haze of pleasure though he didn't stop stroking. He opened his eyes to watch with curious lust as the bulge continued to move. It felt like he was being stretched open and it felt like the relief of using the loo, and distantly he wondered if that was what was actually happening since it wasn't like he had an arse. 

That was why Harry twisted to make sure that whatever came out would land on the floor. When it did, there was a wet splat, and then Harry started coming with his other cock because of the sheer amount of relief and pleasure that was felt as soon as it was over for the new appendage. Only after he finished coming all over the mess on the floor did he release his still-hard cocks so he could get a closer look. It definitely didn't look like shit, and a taste of the air confirmed that what he was seeing was actually an egg since the scent of broken yolk was very strong.

For some reason, part of him felt rather heartbroken that the egg was shattered on the ground. There was a sense of loss there, like something that could have been loved was gone. Harry's bottom lip quivered as he recoiled back onto the bed to get away from the sight and smell of the egg, then he hugged himself and quietly mourned. He mourned for Sirius, he mourned for Cedric, and he mourned for himself, and after crying for several minutes he pulled himself together because he still needed to figure out if he could go back to being a human or not.

The first thing Harry did once he stopped crying was to clean up the mess - and he felt silly as he did it. Crying over a broken egg! The eggs were not fertilized and they did not have babies. It was just like the eggs in the cartons that he used to cook breakfast with.

That reasoning made Harry feel a lot better. So much so that he was ready to tackle the problem that was his tail. He started by thinking how he wanted legs, yearning to be human again, but that didn't work. He got back on the bed and tried meditation... and he fell asleep.

When Harry woke up, it was to sunlight on his face and no more tail. Not only did he have no tail, the scales that had peppered his lower belly and legs were gone. He quickly got up, got dressed, and went downstairs to cook for the Dursleys before he was yelled at. Once that and his regular list of chores were done, he returned to his room. Then he pulled off his pants and underwear and tried willing the tail back, and when that didn't work, he closed his eyes and imagined how it had felt the night before.

The shift this time was quick. Scales blossomed out and his legs automatically moved together to meld. Harry pinwheeled his arms for balance as the tail grew out in the blink of an eye, failed, and landed face first on the floor with a thunk. He held his breath and silently stayed that for several long seconds to see if the Dursleys would say or do anything, and when no shouting came up from below, he pushed himself up. Now that it was daylight, he could also see a smattering of tiny black and green scales freckling his shoulders and upper arms, and Harry wished he had a mirror in his room so he could take a look at himself again.

Harry practiced shifting between the two forms for the next hour and decided that he was not a were-snake after all. He knew he needed to do some research before the Order came to get him, so he threw his clothes on and went to the local library. There, he looked for anything that was half snake and half man in the mythology section of history, and he finally stumbled across the Naga.

They apparently had an affinity with water, and it would explain how he was able to adjust so well to the Black Lake even though he had never swam in his life before. They were also somehow tied in with dragons which... well, there were a lot of coincidences in his life that he didn't think were coincidences. There was a lot of ties to religious lores, but Harry skimmed past those. And aside from those things, there wasn't much else he could find.

Harry thought about what he had read as he walked home, and he wondered what the wizarding world would have to say about them. Probably nothing good since they would be considered non-human. 

And that was when Harry realized he wasn't human any longer and spent the last several days until Dumbledore picked him up having an existential crisis.

After a bit more research in some of the books at the Burrow, Nagas were apparently a very shy race of Beings that only lived in Asia, but they were so rarely seen that hardly anything was known about their abilities. They were said to be inhumanely beautiful, could attract mates more than veela could, were very long lived, and could extend the lives of humans by a few decades if a human bore their eggs.

How long lived it didn't say. That was pretty much the extent of his information, and it came from a children's book called 'Beings Throughout the World.'

One thing that confused Harry did happen at the burrow, though. He and Ron had been rough housing, and he bit Ron on the meaty part of his shoulder out of reflex. Ron shuddered hard underneath him and went still, and Harry quickly pulled away thinking he had hurt his friend. He saw two puncture marks on Ron's shirt and a little bit of blood, and he cautiously asked Ron if he was okay.

"I'm fINe," Ron said, his voice cracking in the middle of the second word. "Just erm... out of breathe. Will you -er- make us some tea? Think I need a break."

Harry had fled, scared that Ron was going to die of poisoning. He made tea and wondered what excuse he would give - could give - about why Ron was sick on the living room floor. He returned to the living room to check on Ron only to find Ron missing, then he checked the floor and saw a little wet spot. A quick scenting of the air told him it was come and... he realized that Ron must have orgasmed and that was what the shuddering had been about. He was no doubt in their room changing so Harry had retreated back to the kitchen to finish making the tea just in time to hear Ron dash down the stairs.

They both pretended that didn't happen. Harry acted ignorant. Neither had rough housed for the rest of the summer, though they still played Quidditch and did other things, and by the time Harry got to Hogwarts, he had settled into his new skin while Ron had calmed down and acted normal.

However Harry thought about that incident a lot. Ron must have, too, since Ron often snuck peeks at Harry when he thought that Harry wasn't looking. Harry's own eyeteeth began to itch with the want to bite Ron again, and he was constantly swallowing back tangy venom any time his fangs peeked out. His gums were sore and swollen, and when he was in the showers, he often wanked to the thought of Ron shuddering with pleasure under him.

It wasn't until the second week of school that Harry began to feel the need to shift. He went to the Room of Requirement to do so in secret, but it didn't make the need go away at all. It was frustrating until Harry pinpointed that the urge only happened when he was relaxing in the dorms, so he started having out more in the common room where the urge didn't make his legs itch.

The third week was when Harry finally tossed on his invisibility cloak to sneak into the restricted section of the library to look for more texts on nagas. He found a couple more books that mentioned them, but again he got very little new information. It was about naga venom and mating habits, however. The venom apparently had mood altering properties that increased the libido (Harry had to look that word up and blushed when he found out), and it was only used on chosen mates.

Mates. Plural. The book also told him that nagas could lay dozens of eggs in one mating season so a single naga often took three or four mates to share the burden with at least two nagas to the group. There were no males or females. A naga was both and neither. The ones with breasts were quarter or half blood nagas where the human side leaked out in that way, however otherwise they looked like beautiful and androgynous (another new word that made Harry pout since it did match him well) males.

Finally, the anatomy and the reason that they mated in groups. There was an ovipositor that inserted eggs into their mate, and a penis that could fertilize eggs that belonged to any other naga besides themselves. Their eggs could also be fertilized while still in the original naga, though they would still need to be put inside a non-naga host. All it took was another humanoid race to insert their penis inside the ovipositor (Harry had to pause for a few minutes here because he was blushing too hard to read) and they could fertilize the eggs if they came enough times. And that was how half nagas were made.

Half nagas were male or female - not both. Some had the ability to switch between legs and tails, but they had to have very strong magic to do so. Nagas usually chose humans as mates since they could hold more eggs than other races could, even the veela, and it was a position that was sought after by witches and wizards in Asia since it kept them looking youthful for longer.

Harry was so distracted by his new instincts that he didn't pay Malfoy hardly any mind except over the 'Weasley Is Our King' problem. He did find himself paying a lot more attention to Ron to help build his self confidence. Potions class was easy with the 'cheater's book' as Hermione put it - and she had started wearing perfume to Harry's disgust so he was staying away from her when he could. Ron actually stuck by his side, and while Harry felt some guilt for abandoning Hermione, it wasn't much since any time they were together she was always harping on about the book.

Halfway through November Harry's instincts took an abrupt turn. He was always wanting to be in the dorm. There was always sometimes he didn't like about it. Too much clutter he needed to clean up, his bed (and the others) weren't made up right, and the shared bathroom wasn't sanitary enough. Harry started learning cleaning charms to keep up with the task of cleaning up after four other teenage boys, and finally when Seamus deliberately made a mess one night with a laugh to upset Harry's 'OCD', Harry pounced on him with a hiss of irritation and bit him at the junction where the neck and the shoulder met.

Unlike Ron who shuddered and then stilled, Seamus bucked up with a moan before he froze. Harry scrambled off him with a blush, unable to believe what he'd just done, and Seamus scrambled back against the headboard with his own blush. Dean and Neville laughed, but when Harry glanced back at Ron, Ron looked away upset. Harry retreated back to his own bed, apologized, and Seamus apologized and promised he wouldn't do that again.

That was when Seamus started following him around. Ron, Seamus, and Harry became a trio, and Ron and Seamus would quibble with each other similar to how Hermione and Ron would quibble. Ron also started becoming more tactile - slinging an arm around Harry's shoulders - and Seamus started copying shortly after that.

Harry of course realized that his venom had caused the sudden shift in behavior. He noticed how the two boys were low key acting jealous of the other. He noticed that the clinging was them trying to subtly be possessive. And Harry couldn't bring himself to say anything about it. A deeper part of him preened under the attention and... he realized he liked both boys.

Their other two roommates also noticed what Harry had noticed, and they seemed amused by the love triangle Harry found himself in. Perhaps that was why Harry started thinking about biting them, too. Perhaps that was why Harry started imagining what it would be like to have all four of his dorm mates swollen with his eggs. Perhaps that was why he started thinking about showing him his tail.

Harry went with Ron to the Burrow over the holidays (and Ron gave Seamus a smug smirk that made Seamus red with anger when Harry had agreed) and he decided that he would show and tell his best friend about it while it was just the two of them. It would be a test run to revealing himself to the other boys. And he was scared, but he was also excited and relieved, too.

"Ron, I have a secret I've been keeping since second year," he late one night a couple days before Christmas. "Don't hate me, okay?"

"I could never hate you, mate," Ron said in a reassuring tone. "You know I'll keep your secret, too."

Harry nodded then stood up and started removing his pajama bottoms. Ron squeaked and turned away with a violent blush, but Harry could tell he was watching out of his peripheral vision. That was when Harry shifted, and he groaned at the relief being in the other form gave him.

"Blimey, you're a naga!" Ron gasped. "How? You aren't even Asian!"

Harry nodded an agreement and slithered closer to Ron who was sitting there in stunned amazement. "It's because of the basilisk bite," he explained, a blush coming to his cheeks as Ron's eyes lingered over his long tail. "There were just a few scales at first, but I actually changed this summer. I had no idea what was going on and thought I was a were-snake until I finally got my hands on some books over the past couple months."

"Can I touch you?" Ron asked. "Are you slimy?"

"Sure," Harry said, and Ron slid down onto the floor and slid a hand down Harry's tail. It was the first time someone touched his tail so he couldn't help but twitch with surprise, and Ron jerked his hand back and gave Harry a worried look. "Sorry, just a little nervous is all. You sure it is okay?"

"Yeah," Ron breathed out as his eyes roamed all over Harry's face and torso. "Is this why you use the private shower stall? Can I see the rest of you?"

Harry shrugged at the first question then raised his hands to start unbuttoning his shirt as a silent answer to the second one. "I used to have scales on my lower belly, though ever since I've learned how to change I go completely from one form to the other with nothing leaking out except for my eyes. At night, in the dark, they turn slitted like they are now so that I can see. And I can always scent the air, too."

"Really?" Ron asked. "What scents are in the air now?"

Harry paused with his shirt open and opened his mouth to breath through it. He twitched in surprise since he could taste really strong lust coming from Ron, and his eyes dropped down to the bulge in Ron's sleeping pants. Ron blushed and covered the front of his pants, and Harry grinned, not minding that his fangs were starting to slide out.

"Yeah, that," Harry said, then he shrugged the shirt off feeling amorous himself. "Do you... want to try? With me?"

Ron's eyes went wide. "Er, is it okay?" Ron asked, then he began to babble. "I heard that sex with nagas can be intense. It's supposed to be better than veelas! Merlin, no wonder I've been so attracted to you all year! It's been so hard not to say anything and I didn't want to ruin our friendship!"

Harry swallowed the venom pooling in his mouth then reached out to unbutton Ron's shirt, and it shut him up. "Nagas take several mates from what I read," Harry explained to a frozen Ron. "I've been wanting to with you since the summer, too." He unbuttoned the last button on the shirt and then slowly pulled on the drawstring of Ron's pants, insecurity making him hesitate. "I want Seamus, too. Is that okay?"

"Oh, that must be what naga orgies mean," Ron murmured as he watched his drawstring get plucked open. "Er... I don't know. I guess I can try?"

Harry moved forward so their chests were pressed together, but with Ron still on his knees it made Harry the taller one for a change. "Take off your pants and sit on the edge of the bed," Harry suggested as he pushed the top off of Ron's shoulders. "I think that would be easiest for us."

"Wait, am I bottoming?" Ron asked, beginning to blush hard. "Er, there's supposed to be preparation for it? I got some lube, sec!"

Harry watched Ron scramble to the bedside table, pull out a bottle out of the drawer, then kicked off his pants. Harry hadn't considered who was bottoming, but he supposed that Ron was right since he had no idea what he was doing. He just wanted Ron's legs wrapping around him while he rubbed his slit against Ron's cock - but Ron's way made more sense than that.

Ron positioned himself so that his feet were braced on the end of the bed with his legs spread wide open. With shaky hands, he poured lube out onto his fingers, then he raised his hips in the air so that he could put a finger inside of his butt. His decently sized cock was already hard and weeping, and he only pumped his finger in and out a couple times before he started sinking the second one in.

"Two is the most I've gone," Ron groaned, this time going much slower. "Help me out, mate. Just hold my knees to my chest so my arse is further up."

Harry slithered right up against the bed and pushed Ron's knees up. It gave him a better view of that Ron was doing, and he felt his cocks begin to slide out of the slit as he watched slick fingers move. Ron then twisted his wrists, seeming to be searching for something, and he gave a gasp.

"There's a spot... It feels good..." Ron panted out. "I always wanted... to feel a cock there. Feel full. I came in my pants when we wrestled this summer. Been dreaming of this ever since."

Harry grinned when Ron admitted that out loud. "I know," he said, and was a little surprised by how husky his voice sounded. "My bite increases the libido. I didn't know that until a few weeks ago."

"Really?" Ron breathlessly asked. "Bite me so I can add a third finger?"

Harry licked his lips and eyed the deliciously pale skin of Ron's inner thigh. He lowered his head, laved his tongue over the spot he wanted, then sank his fangs in. Ron quietly keened in the back of his throat as Harry massaged the roof of his mouth with his tongue to milk out some venom, then he removed his fangs so he could pull back and look at the puncture marks.

They were sealing themselves closed as he watched. The only trace that remained was a small smear of blood, and Harry leaned in to lick even that.

Ron was quietly moaning as he rocked his butt back into his fingers. Harry saw there were three in there, and he let go of one leg so he could grab the bottle of lube because it looked like the slickness was drying out. He poured it directly over the hole, making a mess on the edge of the sheets and bed frame, then he dropped the bottle within reach of them both and pushed the leg back.

"Can I taste you?" Harry asked as he looked at Ron's angrily red cock. 

"Yeah, do anything you want to me, mate," Ron moaned. "So close."

Harry lowered his head and laved the underside of Ron's cock from root to tip. That was all it took to make Ron gasp and orgasm so hard that the ropes of come hit the underside of his chin. Harry kitten licked the glans while Ron continued to come, and when Ron began to give pained whimpers, he stopped and lapped up some of the come on Ron's chest. It was delicious.

"Fuck fuck I'm ready," Ron said as he pulled his fingers out. "I need you in me!"

"Shhh," Harry shushed, but he still let go of one of Ron's legs and lined up his cock. It was already slick from the substance inside of his slit so he didn't need to use the lube, and Ron's hole was so slick from the extra lube that Harry had poured that his cock slipped around a couple times before it caught on the edge of Ron's rim. He watched as it slowly swallowed the head of his large cock, and once it popped in Ron whimpered.

Harry immediately stilled and looked at Ron with worry though all he wanted to do was slam further inside the tight hole. Ron was gripping his blankets and straining so hard to be quiet that the tendons in his neck were popping out.

"Should I stop?" 

"No!" Ron gasped out. "Just give me a minute."

Harry nodded and waited, and when Ron began to relax he started undulating his tail to press in deeper. Ron was taking long and deep breaths as he grimaced with pain, but he still didn't say anything so Harry continued to sink in until Ron had taken his full length. That was when Harry stopped, let go of Ron's other leg, and he leaned down to lick up the come on Ron's neck and chin.

"You are so big," Ron groaned as he wrapped his legs around Harry's tail and bared his neck to Harry to be further licked on. "I think I'm ready."

Unable to resist, Harry bit into Ron's neck and Ron's legs tightened as he moaned. Harry started rutting deep inside of Ron until he began to come, and that was when he began to undulate into longer strokes.

Ron's moaning was beginning to get noisy, so Harry raised his head then grinned at how glazed Ron's eyes were. He hesitated for a moment since he wasn't sure if he could or should, but Ron started letting out a loud moan so Harry sealed their mouths together to stifle it and kissed him. Ron wrapped his arms around Harry's neck and held him as he deepened the kiss so that their tongues were wrestling against each other, and Harry sucked down the next moan when Ron began to jerk with another orgasm.

Feeling Ron's hole tighten even more around his cock made Harry lose control. He started pounding hard into the redhead, only being mindful to not let the bed slam against the wall. Ron helped by grinding down with every thrust, and just as Ron finished coming Harry came. He came and came until Ron started squirming with discomfort, then he abruptly pulled out his cock so that the last few ropes splattered all over Ron's crotch and lower belly making Ron even messier than he was.

"I want to use my other cock," Harry panted out after be broke off the kiss. Ron was panting even harder under him and had gone limp as a noodle, but he nodded an agreement. 

"You're going to have to do all the work, mate," Ron groaned. "Think I pulled a calf muscle."

Harry grinned, then he put one of Ron's legs onto his shoulder so that the other Gryffindor was spread wide open. Come leaked out of his ass as Harry lined up his narrower ovipositor, then he pressed it in. The pleasure was different from his cock - more sensitive, really - and it only took a few pumps to feel the first egg drop to the base.

Ron moaned as Harry pulled the other leg onto his other shoulder and pushed Ron down into a mating press. With the extra 'height' his tail gave him, he was also able to kiss Ron as he continued to undulate his tail. Ron whimpered when the bulge pressed against his rim, then sighed into the kiss when Harry had a weird but pleasant orgasm that pushed it past that. Then a second egg dropped when the first was only halfway through and he started panting into the kiss.

"Feels so good," Harry moaned, then pressed their mouths together to cut off Ron's own moan. Ron suddenly came alive under him as the second egg passed the rim and began to claw at Harry's back while he bucked his hips up. Harry lowered himself so that Ron could rub his cock against Harry's smooth belly scales, and then his clenching and unclenching hole helped suck both eggs out of the ovipositor and deeper inside of him.

Harry moaned again and began laying another egg inside of his best friend. The thought of making Ron go downstairs in the morning with a swollen belly was a wonderful one, and going by the way that Ron continued to buck and writhe up against him, Ron probably agreed, too. They continued to messily kiss to cut off each other's moans as Harry laid egg after egg inside of Ron, and when he counted six, he pulled out, lined his regular cock up, and sheathed himself in one thrust so he could come that way all over the eggs inside of Ron.

Harry knew he couldn't fertilize his own eggs, but something in him still drove him to keep coming until he finally ran out. He kept his spent cock inside as he lazily continued to kiss Ron who was shaking hard with exhaustion as he kissed back, then he finally pulled out to look at the mess that was made. Ron's hole immediately began to leak and come was smeared all over the front of both of their chests, and Ron's eyes rolled up as he fainted leaving a panting Harry the only one left to clean up.

"Merlin, that was intense," Harry groaned, tired himself. His belly muscles burned and ached from all the work he had done, but he wasn't going to leave Ron like that. He transformed back to his regular body, pulled on his pants, then grabbed a couple towels. A shower for him first, then he would grab some wet hand towels to wipe Ron since he should have stopped leaking by then.

And if Harry spent some extra time rubbing and nuzzling the little bulge in Ron's belly, nobody needed to know.

Ron couldn't move for the next two days so he acted sick. Harry would bring him his meals so he could eat in bed, and then he would go back to his naga form and lounge next to Ron with his coils draped over Ron's body so that Ron could pet it. They talked a lot in quiet whispers during that time, but eventually Harry had to help Ron to the bathroom and Ron 'laid the eggs' into the toilet.

It was apparently a pleasurable experience for Ron since he got hard during it, and when they returned to the room, Ron could finally walk on his own though there was definitely a limp to it. Harry tucked Ron into bed, then he slid under the covers and sucked Ron off for the first time. The come was as delicious as it had been the first time, and since Harry had no gag reflexes, all he had to do was learn how to breathe through his nose while he let Ron face fuck him as he wished.

They had sex one more time before school started, but Harry wasn't allowed to lay eggs inside of Ron. Ron was a lot more coherent for the second time, and they cast a silencing charm over themselves and the bed so that they could bang it about as they wished. That meant that when someone started coming up the stairs, they were able to break apart. Ron stayed under his covers as Harry scrambled into pants, and he no sooner sat down on the edge of his own cot before someone knocked on the door.

They both looked at each other with panic because even if Harry was dressed and Ron was under the covers, the room very much smelled like sex. And then the door opened.

"Boys, are you-" Mr. Weasley began, then he jerked back because he no doubt smelled the room. "Er, sorry, I'm sure you boys know to be packed up for tomorrow. Goodnight!"

And then Mr. Weasley closed the door and practically ran down the stairs. Harry started to silently giggle at first, then Ron did. A minute later, they were both howling with silent laughter and rolling in their beds to try to contain it, and once they calmed down and removed the silencing spells, they both decided to air the room out and then go to bed.

The next morning, Mr. Weasley kept sending them looks that Harry didn't know how to interpret, then he pulled them to the side after breakfast. "Now I'm sure neither of you boys are the type to take advantage of someone, but I need to ask if either of you are uncomfortable with what you are doing," he said. "Are you two dating? What is going on here?"

Harry and Ron glanced at each other, and Ron indicated for Harry to take the lead. "I think we are dating, sir," Harry said, and Ron nodded so Harry relaxed. 

"You think or you are?" Mr. Weasley asked a little more sharply.

"Kind of are," Ron said. "We are talking about..." Ron peeked at Harry. "Adding a few more people to our relationship."

Mr. Weasley's eyes widened and then he awkwardly cleared his throat. "Right, well, as long as everyone is willing and consenting, that is fine," he said. "However such relationships requires a lot of work and trust to maintain. It is more difficult than the traditional relationship. The important thing is that are you two happy?"

Harry was sure that his smile felt as dopey as Ron's looked as they both nodded. 

"Good," Mr. Weasley said, firm but still awkward. "Good talk, boys. Let's not tell your mother about it yet. She's a bit more traditional."

On the train ride back to Hogwarts, Ron made sure that their compartment only had him, Harry, and Seamus in it before he left to go on his prefect rounds. He winked at Harry on the way out and waved at Seamus with a friendly smile.

"Ron is in a good mood," Seamus said, not knowing that Ron was deliberately trying to give Harry time to broach the dating subject with Seamus. "Why's that?"

"We had a good Christmas," Harry nervously replied. How does one say they are a naga who wants to start a harem-like relationship? "Erm, so I need to talk to you about something."

For some reason, Seamus' expression fell. "Oh, you don't want to be friends with me anymore?"

"No! Yes!" Harry yelped, then took a deep breath and tried to explain it. "I mean yes, I want to be friends but no, because I want to be more than friends. And Ron is okay with that." More than okay, really. Ron said there was no way he would be able to keep up with Harry in bed and he finally understood why there were orgies because it was too much for one person to take. "Uhm, but Ron and I are also dating."

Seamus looked elated at first, but when Harry added the last he seemed confused. "Wait, so you want to date both of us?" he asked. "Would I be dating Ron?"

Harry blinked since that was a good question. "Not if you don't want to?" he said. "That's something you and Ron would have to talk about, I think."

"I don't know, mate, I'm not the sharing type," Seamus said.

"Well, there's one more thing, too," Harry said, then he drew his wand and cast the locking charm on the door. "I think there is just enough room in here."

Seamus looked confused, and then bewildered when Harry began to pull his pants off. "Er..." he uncertainly said, but didn't go further since Harry's shirt was long enough to cover up his privates. Then Harry took a deep breath, transformed, and his coils took over the carriage floor and Seamus jerked his legs up into the chair with a yelp. "Blimey!"

"I'm a naga," Harry explained with a shrug. "I was bitten by a basilisk in second year, and it's been changing me ever since. I finally transformed over the summer."

"Blimey," Seamus gasped, though this time in awe. "Thought they were just a bedtime story! Can you really lead people to the fountain of youth?"

Harry blinked since he hadn't heard that one, then he grinned when he realized what Seamus meant. "That is actually part of the mating process," he said. "I can extend a wixen's life through sex, yes. However mating with me is... intense. It's why nagas form groups of mates."

Seamus made a face. "Groups?" he asked, then he snapped his fingers. "Oh! Naga orgies! I thought that was just a saying for really good sex."

"Has everyone heard that term besides me?" Harry pouted. "Even Ron mentioned that."

"Er, no offense mate, but you never seemed interested in that kind of talk before," Seamus said. "You didn't seem interested in anyone and have rejected every girl to ask you out."

"That's because they wear perfume and it tastes gross," Harry explained as he began to settle in. "Heightened senses. I can taste things and emotions in the air, and I can see in the dark even when I'm not in my naga form. I also have venom that increases the libido."

Seamus looked thoughtful, then he frowned as his eyes snapped to Harry. "You bit me earlier this year!" he accused, making Harry tense up. "I wasn't interested in you until then! Well, I wasn't seriously interested in you until then, anyway." Then he gave a low whistle. "But damned if that bite didn't get me going. I wanked to it for weeks!"

Harry slowly relaxed at the last two sentences. "Are you mad at me?" he asked uncertainly. "I actually didn't even know what nagas were until I turned into one this summer."

"A little?" Seamus said, sounding uncertain himself. "Or I think I should be but I don't think I am." He paused. "Can I touch your snakey bits?"

Harry nodded, then with a little effort, he raised a portion of his tail up onto the bench next to Seamus for the other boy to stroke.

"So how does sex with a snake work, anyway?"

"Er, well, I kind of have two cocks, but one is for laying eggs," Harry awkwardly explained with a blush. "They come out of a slit here-" Harry pointed out where "-and from what I read, the one that lays eggs can also be used by humans to fertilize the eggs before mating. Since I don't think having naga babies is a good idea, I'm not letting anyone fuck it."

"Can I see?" Seamus asked.

"Uhm, I have to be turned on to get them out," Harry said, blushing even harder. "And that's like asking if I can see your cock, you know."

"You know we all compare cock sizes when you aren't around?" Seamus asked with a large grin. "You're the only one that we don't know the size of. I'll show you mine if you show me yours."

Harry laughed, but curious he also nodded. Seamus stood up, opened up his pants, then lowered both it and his underwear. He started stroking his half hard cock, then he stopped. "Actually, why don't you bite me to get me hard?" he suggested. "I'd like to see if that really was as good as I remembered it being."

Harry transformed back, then he stood up and switched to Seamus' side of the compartment. Seamus willingly sat down when Harry tugged on his shirt, and then Harry pulled him to his chest and bit his neck from behind as he looked down Seamus' front to watch his cock grow.

Seamus immediately arched into the bite and bared his neck further with a moan. His cock quickly grew, and Harry was impressed since it was at least six inches long. He reached down and gripped it, and Seamus' immediately grabbed his wrist not to stop him, but to encourage him by moving it up and down.

"Harry," Seamus moaned as Harry pulled his fangs out and started licking Seamus' neck. "Fuck, yeah, that feels so good."

"Let me suck you off," Harry moaned against Seamus' skin, feeling his own cock harden. "I want a taste."

"Yeah, yeah," Seamus agreed, sitting up. Harry slid to the floor and got between Seamus' knees, and he kitten licked the tip to lick up all the pre before he took it into his mouth. It only took a few sucks to make Seamus come, and he did so with a long and lewd moan. 

Harry moaned himself as he drank down all the come, and once Seamus was done coming, he gentled his mouth back into kitten licks to make sure he got every last drop before he sat back on the floor with his legs spread open to show Seamus his own larger cock.

"Fuck, that's the biggest dick I've seen," Seamus cursed. "Can I touch it?"

"Please do," Harry said. "It's even larger when I'm in naga form."

"I bet," Seamus said, then he patted the seat next to him. Harry got up to set next to Seamus, and Seamus immediately took him in hand and began to stroke. Harry spread his legs open even more, and just as it started feeling really good Seamus spoke up. "Can I touch it in your naga form? I want to see your other cock, too."

Harry blushed, but he nodded then closed his eyes. The carriage suddenly became more cramped for him, and since Seamus had been holding his cock, it was already out of the slit and the second began to slide out.

Harry opened his eyes to watch Seamus touch his cocks before he plunged a finger inside of Harry's slit. Harry's tail jerked and pressed upward as he gasped with pleasure, then a second finger joined the first and Seamus grinned when Harry moaned.

"I get that I can't fuck the other cock, but can I try sticking my dick in here?" Seamus asked as he fingered Harry's sensitive insides. "Seems like there is room."

"I uhm... sure," Harry said, uncertain and a little scared. "Just go slow. I haven't done this before." He paused. "Does this mean you will date me?"

This time it was Seamus who hesitated. "I don't have to date Ron, right?" Harry shook his head no. "Then yeah, I want to date you, too."

For some reason, the agreement made Harry feel a little used. He didn't say anything though as Seamus straddled him, then he used one hand to hold the slit open with scissored fingers and the other to guide his cock to Harry's slit. They both groaned as it sank in, the slickness inside making it easy, and it only took a few seconds for Dean to completely sheath himself inside.

The end of Harry's tail curled with pleasure when Seamus took both of Harry's cocks in hand to stroke them. "I'm not hurting you, am I?" Seamus asked as he gently rutted into Harry.

"No, it's fine," Harry said, pushing side the feeling of being used since this was what he wanted. "It feels good."

Seamus nodded, then he pulled out part of the way and pushed back in. Slowly he increased his own pace until it matched the stroking of Harry's cocks, and then his hips started stuttering. Harry felt his slick insides get a little slicker, and the thought of being come inside of was enough to tip him over the edge. His main penis began to come, but Harry clenched his insides to hold back from dropping an egg since he wasn't comfortable doing it in front of Seamus.

"Merlin, that is so much cum," Seamus said, his eyes wide with surprise as ropes shot up and then splattered down on Harry's shirt and the bench. "That's just..." Seamus swallowed hard as his eyes glazed over with imagination. "Think I'll like having you inside me, too." Then he grinned down at Harry. "We get to do this often, right?"

Harry was still hard when he stopped coming, but he still pulled himself up so that Seamus would get off of him. "We don't really have a place yet, not unless I can get Neville and Dean to also date me," he replied, the orgasm leaving him feeling a little hollow. He really shouldn't be feeling bothered but... "You do like me right, Seamus?"

"Yeah, I wanted to date you before you said you were a naga," Seamus pointed out, and Harry felt a little relieved. "I only hesitated because I didn't want to date Ron and didn't really want to share you with Ron. How will this work? And why do you want more people to date?"

"Ron can't keep up with me," Harry said, then transformed back to human and gestured at his still hard cock. "Took coming around a dozen times before it finally went soft, and Ron passed out as soon as I was done. Then he couldn't move for two days. And I could have still gone longer if I had wanted."

Seamus laughed, but he stopped when he realized Harry was being serious. "Oh, huh, well I guess with that much stamina just one or two lovers won't cut it," he agreed. "You should try Neville next I guess, but not for a while please. I do want some time to have you, and I already share your time with Ron."

Splitting his time between two boyfriends was a little difficult but doable. When Seamus was with Harry, Ron started hanging out with Hermione again, and when Hermione learned that it was her perfume - all girl's perfume - driving Harry away because of his sensitive nose, she stopped wearing it and the four of them hung out together during 'Ron's time' because Ron wasn't too fussed about alone time with Harry. He was happy getting to drape himself across Harry's back or pulling Harry into his lap when the four of them hung out, but Hermione was always eyeing the three of them like she was puzzled.

Sex was shared between them, and it was usually done in the dorm though Harry did get frustrated once and pressed Ron who had been teasing him all day into an empty classroom before dinner while Seamus kept Hermione occupied at the library. Since it was too risky for Harry to change into his naga form, more usually he would go a couple rounds with one and then the other in his human form every few days. Only once did they share a time together, and that was when Harry agreed to take it up his bum for the first time at Seamus' request. Ron prepped him since he was better at it than Seamus was, then Ron took his mouth while Seamus took his butt.

"Harry, what's going on with you, Ron, and Seamus?" Hermione finally asked one day in the common room.

"Oh, I thought Ron told you," Harry said with a glance at Ron who shrugged. "I'm dating the both of them but they aren't dating each other. Seamus needs one on one time with me, but Ron likes to hang out as a group."

Hermione opened and closed her mouth a couple times. The first time she looked like she was going to lecture Harry, but she stopped it before anything could come out. The second time had her looking confused, but she snapped her mouth shut pretty quickly. The third time she opened her mouth, she looked cautious. But she actually voiced what she wanted to say. 

"Why?"

Harry looked at Ron and Seamus to see if he should tell her the truth, and they both shrugged saying it was up to Harry. Harry sucked on his lower lip as he thought about Hermione, then he recalled how she advocated for rights for house elves and werewolves. 

"Guys, bring her to the dorm in five minutes?" he asked as he he pulled himself up off the couch. "I'm going to make sure it's empty."

"Sure," Seamus answered for both him and Ron.

Harry went up the stairs and entered the dorm, and Neville was sitting at the desk tending to his stink sap plant. He was carefully harvesting the sap from it, so Harry closed the doors behind him and cleared his throat. 

"Neville?"

"Yeah, Harry?" Neville asked without looking away.

"How long are you going to be?"

"Probably another fifteen, why?"

Harry bit his lower lip. "Well, I wanted to show Hermione a secret, but..." He did want to introduce Neville to it. Perhaps doing it with a group he trusted would be best. "Do you want to know it, too? Will you keep it a secret?"

Neville set down the scalpel and vial to give Harry his full attention. "Do we need to raid another top secret department in the ministry?" he asked, then grinned. "You know I'll take your secrets to the grave. Even the illegal ones. Is it about how you are dating Ron and Seamus? If so, I already know."

Harry chuckled as he relaxed. "Well, that's the question that started it, but she asked why."

"Why does it matter why if you three are happy?" Neville asked.

"Er, cause of the secret I've been keeping," he said, then he recalled what Seamus said on the train. "The reason why I don't show off my cock and stuff."

Neville raised his eyebrows in shock. "Wait, are you... Do you have girl bits?"

"No!" Harry spluttered, blushing with embarrassment. "No, it's not like that!" He paused and glanced at the door knowing there was only a minute left. "I'm a naga. Since second year, I was slowly changing but had no clue. I transformed completely over the summer."

"Oh." Neville paused. "That explains how you are a parselmouth, I guess. Congratulations?"

Harry helplessly laughed, and then someone knocked on the door behind him. He turned to open it then gestured for the other three to enter. "I'm going to go to the bathroom real quick," he said. "Just take a seat."

Hermione sat on the edge of Harry's bed and Ron and Seamus sat across her on Ron's bed. Harry went to the bathroom, then he stripped down to only his shirt and transformed. When he started slithering out, he only poked his head and his arm out from the doorway and cleared his throat to get Hermione's attention. Neville's bed was closest to the bathroom so he could see Neville already looking him over with a curious gaze, but Hermione did a double take.

"Your eyes!" she gasped. "They are slitted like You-Know-Who!"

"This actually has nothing to do with Voldemort," Harry said, then he began to slither out. "I'm a naga."

Hermione gaped for several long seconds, then she got up and rushed over to him. "Oh my god! Or is it actually oh my god? Did you know you can be considered a divine being in India, Thailand, and some other Asian countries? And in the wizarding world, you can actually sell your venom for a lot! When did this happen? How did you hide it? Why-"

"Merlin, let him answer!" Ron laughed. "It's not a very long story, not really."

"Er, so, remember I got bit by the basilisk?" Hermione's eyes went wide as she nodded. "So there were little changes. Like I grew a few scales, then I started being able to taste the air and I could see in the dark and stuff. But this past year it got worse. The scales on my belly grew all the way down my legs which is why I kept covered up, and then over the summer I actually transformed on my birthday. I didn't know anything about nagas so I checked the local library first, and got all that religious stuff. I think the stuff about water and dragons are true though, cause how else do you explain fourth year?"

Hermione hummed as she gave a thoughtful nod. "And you are dating Ron and Seamus cause of the naga's mating habits," she said. "It still doesn't explain why you kept it a secret, though. Don't you know that if the ministry knew, they would not have been able to touch or slander you last year without the Asian ministries jumping in to defend you?"

"Er, no," Harry said with a surprised blink. "I'm not Asian. And I said nothing because I thought I would be treated like werewolves and other non-humans are."

"Still doesn't matter, there are international laws about nagas," Hermione said. "They are actually one of the few things considered higher than a human along with phoenixes. People will do anything to become a naga's mate for the longevity itself since it extends youth, not the end of the life like the philosopher's stone does."

"She's not wrong," Neville chipped in. "But I've always just known Harry so the naga part doesn't matter to me."

Harry glanced at Neville then gave him a fanged grin. "Funny you should say that," he said. "I've actually been wondering how I was going to ask you out."

Neville blushed and Hermione giggled. "Then all we need is Dean and we can have-"

Ron slapped a hand over Seamus' mouth. "There is a lady present," he said. "We shouldn't say that kind of stuff in front of her."

"Oh, that explains all the cleaning and stuff that Harry does," Neville said. "He's turning our dorm into a nest and preparing for mating season."

This time Harry and Hermione both blushed. "Mating season?" Harry asked.

"Merlin, he's still impossible to satisfy with two of us," Ron groaned. "You mean it gets worse?"

"I'll just leave now," Hermione said as she backed away towards the door. "You three sound like you need to talk. Should I send Dean up here?"

Harry looked to Neville for guidance and Neville nodded. "Would be a good idea, and Professor McGonagall, too," he said. "If Dean says no, then he will have to be moved into an upper or lower year dorm."

"Does that mean you are saying yes, Neville?" Harry asked.

"As long as you don't stuff me with fertilized eggs," Neville said with a shrug. "Since there isn't a second naga around, I should be safe, and not only will I be helping out a friend, I'll be having fun doing so."

"Er, actually, we can fertilize his eggs if we fuck his second cock," Seamus blurted.

"And I'm gone," Hermione said, and practically fled out the dorm.

"Right, but none of us are going to do that unless you want to be up the duff for eleven months, Seamus," Neville said in a dry tone. "Then you lay them, they hatch in two to three weeks, and that is just in time for the next mating season."

Seamus had paled and was shaking his head no to both Harry and Ron's amusement. "How do you know so much, Neville?"

"My gran got picked as a mate one season, and she loves to talk about it," Neville said with a shudder. "It's an actual dinner topic when we have guests. Just don't tell my gran and we are good, I don't want her to use me as a dinner topic, too."

All three of them laughed, and that was when a short rapping came at the door. Ron got up to go answer it as Harry looked on, then Professor McGonagall stepped in only to come to a complete stop with a gasp of shock.

"I thought she might have just been taken in by a prank!" Professor McGonagall said, then she reached out the door to pull Dean inside and quickly closed it. Harry realized then that he was still in his naga form as Dean gaped at him, and he self consciously coiled his tail closer to himself as he fought the urge to flee back to the bathroom to hide. "I dare say you make a very stunning naga, Mr. Potter. The basilisk, was it?"

"Yes ma'am," Harry said. He briefly wondered how Hermione told the teacher that so quickly, then decided it was not good to underestimate how fast Hermione could talk and how quick Professor McGonagall could pick up on things. "Neville says I'm turning the dorm into a nest."

"He's been cleaning it up and is always nitpicking things," Neville said.

"Aye, he even angrily bit me the time I purposefully dropped a gobstone just to see his reaction," Seamus cheerfully chipped in. "Was one of the most frustrating nights of me life if you know what I mean?"

"Yes, I know what you mean," Professor McGonagall said in a dry tone. "Are you three joining Mr. Potter in his nest then?" Ron, Neville, and Seamus nodded, so she turned to Dean. "And you, Mr. Thomas?"

"I'm still... trying to figure out why Harry has a snake tail," Dean admitted. "What's happening?"

Neville began explaining what Harry was to Dean while Professor McGonagall approached Harry and started casting spells on him. Harry flinched the first couple times, but he quickly recognized it as diagnostic spells and relaxed. Finally, when Neville was done talking Professor McGonagall spoke up.

"Interesting, you register as fully human on most scans even in this form, Mr. Potter," she said. "You also register as a snake on others meant to detect animals. Only a couple that are specifically meant to detect magical beings register you as naga. No wonder nobody has found out."

"Uh, can I ask to be bitten before I decide?" Dean asked before Harry could reply to Professor McGonagall. "I can't figure out what the fuss about the bite is, but I remember that night you bit Seamus."

"Not while I'm still in here!" Professor McGonagall said before Harry could agree. "And your decision shouldn't be based around a bite. Some nagas expect their mates to stay around for many, many years in a relationship while others are fine for only one mating season. You should find out which one Mr. Potter is!"

"He's the type to date, professor," Neville answered for Harry since Harry had no idea. "He's already dating Ron and Seamus, and he asked me to date him. It isn't even the right season, so it isn't just about mating for him."

Harry nodded an agreement and looked at Dean. "We've shared the same dorm for almost six years and know each other well," Harry said to Dean. "I like you as a friend at least, but as Seamus told me when I first asked him out, I don't share. I don't care if you guys want to date each other, but I don't really want anyone outside our circle to be part of it. Not unless all of us vet them."

"Which means no Granger," Seamus added with a shrug. "I'm starting to get to know her better and am starting to get used to her as a friend, but I don't like like her since she's pretty bossy."

"What about after we graduate?" Dean asked. "How will that work?"

Harry looked up at the ceiling in thought. "I have enough money to get a large house," he said. "And Hermione said something about selling my venom, too, so there is that."

"Alright, I'm in," Dean said. "Ginny broke up with me so I'm single again, and this sounds interesting."

Harry's coils loosened as the tension in Harry's back eased up and he nodded. "Right, so what does this mean, Professor?" he asked as he turned to Professor McGonagall. "Making my nest?"

"You will be able to redo the dorm however you all wish within reason," she said. "If none of you agree with a layout, then this will remain the layout. I will go let the headmaster know, and he can send in the paperwork to the ICW who will then send it to the ministry since your race is protected on the international level much like dragons, phoenixes, thunderbirds, direct descendants of Merlin, and horned serpents are just to name a few."

Harry nodded then looked at the others. Ron shrugged indicating he didn't care, Seamus looked at his own bed longingly, Neville gestured to his own plant to tell Harry what was important to him, and Dean still looked confused and a little overwhelmed. "We will talk about it, professor," Harry said to her then smiled. "Thank you." He paused. "And nobody will care that I'm a naga when it gets out?"

"Of course people will care," Professor McGonagall said, and Harry's heart plummeted with dread. "They will want to be around you more. Expect your popularity to skyrocket further, Mr. Potter."

"Wait, what?" Harry choked out, not expecting that. "Why? I thought that people hated half breeds and non-humans. Look at what they said about Hagrid when it came out that he was half giant and Professor Lupin was kicked out because he was a werewolf!"

"You don't hear people speaking that way about phoenixes, Mr. Potter," Professor McGonagall said, then she surprised him by giving him a teasing smile though it was very brief. "If anyone mocks you, their friends will quickly shush them and explain why they shouldn't. If they continue to do so, they will ostracize themselves. Now I will leave you boys to sort things out. Have a good night."

Professor McGonagall left, and Harry stayed in the center of the room still feeling uncertain. "So..."

"Can I touch your tail?" Dean blurted out. "I want to see what it feels like."

Since it was the same thing that Ron and then Seamus had asked, Harry burst into laughter that was tinged with relief. "Sure," he replied. "You too, Neville?"

"Er, if you don't mind?" Neville asked.

Harry smiled then slithered up onto his bed. "I don't mind at all," he said. "Let's talk about the dorm, too. We can redecorate it however we want! How many of you are willing to share a bed and..."

In the end, Ron and Neville were both willing to share a bed with him while Seamus and Dean still wanted their own beds. Harry decided that two sets of bunk beds would work well against one wall, and the other wall would have two Queen sized beds pushed together and transfigured into one. One extra space where the best light was at would have a long desk that could seat up to three with shelves above it for Neville's plants, one corner had an easel set up for Dean's art supplies, and the last free space would have a wardrobe with extra bedding and blankets to change the sheets out when needed or if the other two decided to join them in the bed but wanted their own blankets and such.

Harry also wanted and got rugs. Thick plush rugs. They were made of very soft fur, but they hadn't come from actual animals. Instead it was a permanent transfiguration that had been made by Professor McGonagall, and Harry absolutely loved the thick, red, fur.

The other boys also appreciated the rugs since it meant that they could move around the room barefooted. Harry appreciated it because it felt lovely against his scales. However he only kept his transformation to the room and loved draping himself on one or two of his boyfriends at a time. And even though Dean and Seamus wanted their own beds, the larger bed quickly became a hang out spot for all five of them to lounge on when they had nothing else to do.

However Harry was nervous about broaching sex with Dean and Neville. He was very, very happy to finally fill Seamus' belly with a few eggs, and Seamus didn't have a problem moving around the next day since he was used to being penetrated. And because he could move around, the eggs actually came out after lunch the next day. However he was so reticent about being rejected by the other two that it was actually Dean who brought the topic up first.

"So Neville and I were wondering when it's our turn," Dean said with a grin a few days after Harry was found out. It was afternoon, and Dean was sitting at the easel to draw a sketch of Harry possessively curled up around Neville in his naga form while the lighting was good. Ron and Seamus were hanging out with Hermione at the library doing homework that Harry had already finished, so it was just the three of them. "We're feeling a bit left out, mate."

Harry blushed and nervously tightened his coils around Neville for a brief moment before he forced them to relax. "I wasn't sure you guys wanted to," he admitted. "I mean, I know you said you would for my mating season, but I didn't know how to ask."

Neville tilted his head a little and bared his neck. "Will you bite me?" he asked, and Harry realized that the two of them had deliberately set up the scene since Dean had paused and was watching the two of them intently. "I want to go first and gran always made the first bite sound so... you know."

Harry licked his lips once as his eye teeth began to itch. He shifted to move his upper body behind Neville, his sliding scales making the other Gryffindor shiver, then he nuzzled the back of Neville's neck. Neville breathed out a silent moan as he relaxed back into Harry's arms and tilted his head further, and then Harry slowly bit down as he made eye contact with Dean and he saw the black boy shudder when Neville let out a moan that started off a little pained but turned lewd only halfway through.

"Merlin, Harry," Neville moaned. "Bloody hell, that feels so good."

Harry retracted his fangs and licked the puncture wounds as he slid his hands to Neville's chest so he could begin unbuttoning the shirt. Dean's pupils dilated, and Harry grinned at him when he shifted in a way that told Harry that the other boy's cock was getting hard. Then Harry started kissing and sucking his way up Neville's neck as he continued to make eye contact with Dean, and Neville moaned again.

When the shirt was completely unbuttoned, Harry slowly pulled it off of Neville like he was giving Dean a show. "Let's get you undressed," Harry quietly murmured into Neville's ear as he began to move his tail out of Neville's lap, teasingly curling the tip to trace it along the bulge in Neville's pants as it slipped off. "I'll suck you off first to relax you."

Harry reached down to unbuckle the belt - very well versed in doing it to another now - and Neville lifted up his hips as Harry flicked open the button and undid the zip. Neville hurriedly pushed down his pants in one go, and Harry grinned when he saw that Neville didn't wear underwear. Neville then bought his legs up one at a time to yank off the socks, and then Harry quickly twisted around his torso and latched onto a nipple.

Neville grabbed Harry's head as he arched into the next bite with a pained and pleasured hiss. Harry reached down to swipe a thumb over Neville's slit, then he pulled back and sucked the pre off where both Neville and Dean could see. Neville's pupils were blown wide open as he watched, and Harry heard Dean groan. However he finally spoke loud enough for Dean to hear when he heard Dean undo his zip.

"You aren't allowed to wank," he ordered as he gave Dean a fanged grin. "It will be your turn after."

"Fuck," Dean cursed, but he raised his hands to show he was going to obey and Harry winked at him. "I'll be good."

Harry turned back to Neville and gently pushed him back onto his coils so that he could come at Neville's cock from above. He opened his mouth and watched Dean as he swallowed it down to the root in one go, and Neville scrabbled at his back with a cry of pleasure while Dean's mouth dropped open in a mix of shock and lust. After that, all it took was some undulating while he made swallowing motions around Neville's cock, and when he knew that Neville was about to come, he pulled back to suck on the head like a lollipop while his mouth got filled with come.

Harry very carefully did not swallow as he collected it, and once Neville was left panting and done, Harry pulled back and opened his mouth to show Dean the prize he had gathered. Once Dean got a good look, Harry closed his mouth and swallowed it down, then he turned and stretched to the edge of the bed so that he could snag up his robes with only minimal jostling of Neville and pulled out his wand.

"Get on your hands and knees, Neville, it will be easier that way for your first time."

Neville's cock was still hard as he carefully rolled over so he wouldn't hurt Harry's coils, but that was because of the venom. Harry cast the cleaning and then the lubrication spells on Neville which made him squeak with surprise at the feeling, then he used the latter spell on his hand to slick his fingers up.

"Just relax, I'll take care of you," Harry coo'ed, then he pressed his pinky all the way to the knuckle in without warning.

Neville gasped, and Harry glanced at Dean in time to see him licking his lips with anticipation. Harry pumped it in and out a couple times while Neville squirmed, but one he relaxed Harry pulled it out and replaced it with his thumb. Neville shuddered at the new stretch, and Harry wiggled it a few times before he pulled it out so he could start pressing in two fingers. This time he was much more careful and slow, and he would stop every time Neville tensed up, but rubbing Neville's lower back with his other hand seemed to help the most with keeping Neville soothed.

Harry didn't push the fingers in all the way. He instead searched out the prostate, and when he found it, Neville jolted and moaned. "That's the prostate," Harry said, glancing at Dean to make sure he was listening as he began to attack the spot. "This is what makes getting buggered feel so good if it's done right. Tell me if my prepping hurts too much. Seamus says I'm a little too impatient but Ron loves it."

"Ah, gentler, please!" Neville whined. "It's too much!"

Harry chuckled and began to gently began to rub it. When Neville relaxed and started rocking back into his fingers, he scissored them to stretch Neville out further so that he could press a third finger in. Neville whimpered a little, but since Harry didn't stop rubbing and Neville didn't stop rocking, he assumed that it was a good kind of pain and didn't stop.

"Why don't you come over here and kiss me, Dean?" Harry suggested with a coy smile at the black boy. "I'm sure you are feeling a little left out."

Dean wobbled a little after he quickly stood up, then he steadied himself against the wall before he moved over to the bed. Harry started pressing his fingers in even deeper as Dean crawled his way towards Harry, and once he reached him Harry turned his head to kiss Dean hard.

They tangled tongues for several seconds, then Harry retracted his own to press on the roof of his mouth. His fangs popped out, and Dean began to lick at them and swallowed the venom they gave out. It wasn't long before Dean was affected by the aphrodisiac in them, and he crawled even closer so he could plaster himself against Harry's left side while Harry glanced at Neville's arse to start pushing his pinky in.

Neville watched the two of them snog until he drooled onto the covers a bit, and that made him blush then bury his face in Harry's coils. Harry then grabbed Seamus' right hand with his left, guided it to his slit, and helped Dean slip a finger inside.

Dean broke off the kiss with a groan as he slipped his finger in deeper until he brushed the tip of Harry's ovipositor. "Fuck," Dean cursed. "I can feel your cock."

"That's actually my ovipositor," he said. "You can push your finger inside of it if you want to get me prepared to take Neville."

Dean wiggled his finger in deeper, and Harry moaned when Dean's finger penetrated it. He had yet to have anyone penetrate it with anything, so it was a pleasurable experience for him. He leaned in to nibble on Dean's shoulder, and when Dean tilted his head away in silent permission for Harry to do as he wished, he sank his fangs in. Then he reached out with his left hand to rub Dean's cock through his pants a few times just to tease him as his ovipositor and his cock slid out of the slit.

Dean whimpered at the loss of friction, but he continued to finger fuck Harry's ovipositor until Harry retracted his fangs and sucked on his shoulder. "Those are huge," Dean moaned after he finally looked down. "Will they even fit?"

Harry pulled out his fingers then nodded just as Neville looked over and squeaked when he saw what Dean was talking about. "If Ron and Seamus can do it..." Neville said, then he shivered with anticipation. "I'm ready, Harry."

"I know," Harry said with a quick grin, then he shifted his tail out from under Neville so he could pull himself up. "Why don't you prep yourself while you watch us, Dean? If you can make yourself come while playing your prostate, I'll give you a special reward."

Dean slid off the bed and began to hurriedly undress himself as Harry lined up his cock and began to press in. Neville's ass was definitely the tightest one out of the three people Harry had fucked so far, and he only got halfway in before he started to come. Neville groaned at the feeling of being filled while Harry shallowly rutted where he was, not willing to go deeper just yet, and then Dean was crawling back into the bed and had positioned himself face down and arse up with his arse facing Harry and his knees spread open.

Dean must have already used the cleaning and the lubrication spells on himself since a taste of the air told Harry it was clean and it was glistening with lube, and he started pressing a finger in as Neville began to rock back onto Harry's cock with a moan. Harry realized he was getting a little bit distracted, so he winked at Dean and refocused on Neville by coiling the tip of his tail around Neville's cock and giving it gentle, pulsating squeezes.

"Gonna come again," Neville mumbled, drool making him slur a little. "Need more!"

Harry let go of of his own cock since it was deep enough and grabbed Neville's hips. He pulled back so he could shallowly fuck against Neville's prostate, and when he felt Neville's passage get even more tighter as he prepared to come, Harry pulled on his hips to drag him completely onto his cock then slid his hands up to the front of Neville's shoulders to drag him upright just as he squeezed Neville's cock hard enough to stop him from coming.

"Harry!" Neville desperately wailed out as he thrust his hips to hump the air and clawed at Harry's arms. "Please!"

Harry began fucking Neville hard and bit the back of his neck with a low growl. Neville's passage tightened even further - so much so that it trapped Harry's cock - then Neville wordlessly cried out as his walls began to pulsate with an anal orgasm. With the mix of come and lube, Harry was able to rut inside even if he couldn't properly fuck Neville, then he was coming and Neville passed out in his arms.

When Harry was done, he pulled out then gently lowered Neville onto the bed. "He'll want a second round as soon as he wakes back up," Harry said as he grabbed one of the blankets to cover Neville up. He looked and Dean and saw that Dean was three fingers in and trembling with need. "Need help?"

"Please," Dean whined as he pulled his fingers out. "Can't quite reach it."

Harry slithered over to that side of the bed and pressed two fingers in. Dean shuddered as soon as he found and started rubbing the prostate, and Harry leaned over Dean to lave his tongue up Dean's spine from tailbone to the back of his neck. Then he blew cool air over it as he moved back down, and Dean cried out as he came.

Harry pressed a third finger into the twisting hole, and Dean began to squirm. Harry pinned him down by the back of the neck as he continued to assault Dean's prostate by scissoring his fingers over it, and Dean's cries of pleasure turned into whimpers of over stimulation.

"Want me to stop?" Harry asked when Dean didn't tell him to stop.

"No," Dean brokenly moaned. "Fuck! What you did to Neville was so hot!"

Harry groaned and leaned back over Dean so he could start nibbling on his shoulder. "Tell me what my bite feels like to you," he said. Ron described it as warmed pooling in his belly and groin making him squirm and Seamus described it as a heat invading his veins. He was curious what Dean would say.

"Like fire spreading through my body, but rather than burn it makes my toes curl," he whimpered. "Fuck, just fuck me, please?"

"One more finger," Harry said. He knew better than to go in with only three. That could cause bleeding and he didn't want to tear Dean's rim. He started pressing in his pinky as Dean desperately bucked under him, and then Harry moved past the prostate to fuck Dean with his hand and loosen him up.

Dean buried his face into the covers to let out a sob, but when Harry paused, he continued to push his butt back for more. Harry resumed what he was doing and began to pepper Dean's shoulders with kissed, and when he got to the neck he gave it a proper suck and pulled his hand out. He stroked his cock that was still wet from fucking Neville a could times, then he lined up and pressed in. Dean immediately went boneless under him. and Harry worried that Dean had passed out until he heard Dean's muffled moans into the cover.

"You doing okay?" he asked.

"D-don't stop," Dean choked out. "I'm good!"

"Such a masochist," Harry huffed as he smiled, then he bit down on Dean's shoulder and sank his fangs in though he didn't let out any venom. A dry bite.

Dean cried out and bucked back onto Harry's cock, and Harry let Dean work his way down his thick length. It wasn't until there was only a couple inches left that he thrust the rest of it in, and Dean keened as he came all over the bedding. Harry stilled and glanced at Neville, and he saw Neville laying on his side to watch them and gave him a gentle smile.

"Feeling okay?" he asked Neville as Dean went limp with a sob.

"Never better," Neville said, then he licked his lips. "My turn again after, yeah?"

Harry grinned, then he pulled out a bit then slammed inside. "Yeah," Harry agreed as Dean let out a gasp of pleasure, and then Harry turned his attention back to Dean. He pulled out all the way and flipped Dean onto his back, then he lined himself up and pushed in just as Dean wrapped his legs around Harry's tail. Harry fell forward onto his elbows, and he started kissing Dean hard as he began to pound into him.

Dean whimpered into Harry's mouth as he wrapped his arms around Harry's shoulders, and Harry lapped it up. Harry undulated against Dean as he writhed in pleasure and pained over stimulation, and when Harry glanced down, he could see that Dean's cock was soft but steadily dripping out come. Knowing that he brought Dean down to this state had Harry pulling out so that he could reach down and line up his ovipositor to sheathe it in Dean in one go.

Dean moaned as he arched his chest up, and Harry latched on to bite down on the other nipple he hadn't touched earlier. Dean buried his fingers in Harry's hair as Harry pumped more venom into Dean, then he began to fuck him with his ovipositor. Dean's spasming hole was perfect as it milked out egg after egg, and Harry didn't stop at only a few. He kept going until he could see a very nice bulge in Dean's belly, then he swapped out cocks so he could come all over his eggs.

"No more," Dean brokenly begged as he wrapped his arms around his belly. "Can't fit any more."

Harry pulled his cock out and gave Dean a gentle kiss. "You did so good," he coo'ed. "Take a nap, I promise no more."

Harry glanced at Neville as he stroked Dean's hair, and Neville gave him a lazy smile to show he was willing to wait. It wasn't uncommon for Harry to fuck Ron into this state, so he knew that Dean needed cuddles and to be held. He nuzzled the underside of Dean's neck as he continued to hold and pet him, and Dean quickly fell asleep after one last groan. He kept it up for another few minutes to make sure Dean was well and truly asleep, then he slowly pulled away so that he could turn his attention back on Neville.

"No eggs," Neville said with an amused smirk. "No more biting, too. I want to see what it's like without being out of my mind with lust."

Neville's body was very relaxed and there was still a glazed look to his eyes so Harry knew his venom was still working, but he still gave Neville a sensual smile as he slithered over to the other boy. When he got there, he lowered his head to give Neville a deep and slow kiss, and he moved to lay on top of him. Neville held Harry's waist as Harry reached down to Neville's hard cock, then he wiggled to line it up with his slit and sank down on it.

Neville moaned into Harry's mouth, and that was when Harry grabbed the nape of Neville's hair to pull his head back. Neville tensed up expecting a bite, but Harry just sucked and nibbled on his neck until he started thrusting his hips up to fuck Harry's own hot and silky depths.

Harry writhed in rhythm with Neville's thrusting, and eventually Neville stopped bucking and started rutting as Harry's insides massaged his cock. They rolled together so that Neville was on top, resumed their kissing, and when Neville got onto his knees to properly begin to thrust, Harry pressed two fingers inside his ass. Neville gasped with surprise when Harry began to massage his prostate, but he still doubled down on the fucking and Harry moaned when he felt Neville come inside of him a few minutes later.

Neville collapsed on top of Harry with an exhausted groan. "Kay, I see why it's a dinner topic," he panted out, not seeming to notice how they were both covered in sweat. "Sorry Harry, but I think I'm done, too. Not used to this much physical work."

Harry chuckled and started rubbing Neville's back. "It's fine, I liked that a lot actually," he reassured. "It was very good for me. I haven't been allowed to come that much since the first time me and Ron went at it. Did you know that there's a mini orgasm with every egg I lay? I put ten inside of Dean."

"And you are still hard?" Neville whimpered, squirming a little to feel Harry's hard cock and ovipositor pinned between their bodies. "How?"

"To be fair, I don't think I can get soft in this form at all," Harry yawned, then he focused and shifted to human. Neville seemed much heavier in his weaker body, however his cock was only half hard which was a relief. "This form is sated a lot easier."

"Kay, let's go cuddle Dean," Neville said. "I want a nap."

Neville crawled off of Harry, and they both moved over to Dean. Harry grabbed the clean blanket he had spread on Neville earlier, then he pulled it up over the three of them. Dean ended up sandwiched between Neville and Harry, and Harry yawned one more time before he dozed off.

After that, things became a bit more interesting. Dean and Neville enjoyed having threesomes, and Ron decided to try a week later and became a sporadic addition. Dean also slept with them in the same bed sometimes, and him and Neville experimented with each other for some regular sex one night as well. 

They said they liked it, but they preferred Harry more because it was even more work to have normal sex and Harry made it feel much, much better. Dean gave the analogy that while skirt steak was fine if one wanted something quick and cheap, Harry was more like dragon steak cooked perfectly right.

Seamus was the only holdout, but Harry didn't mind. He enjoyed the one on one time with the Irish boy since it was nice to go at a slower pace, and a few weeks later he relaxed enough to ask to join in as well. He said he wanted to see what it was like, and the other boys happily let Harry mostly focus on him for his first time.

He envenomed Seamus so much that when Dean took his cock in his mouth while Harry took him in an upright position, he loved it and begged for more. Afterwards was a different story, though. He said that he enjoyed it in the moment, but that he really didn't want anyone else to fuck him like Neville had done to Ron so they all made some ground rules.

They were all in agreement that they liked the bite, however Neville said he didn't want to be subjected to more than he could handle.

Ron and Dean were both up for anything.

Seamus didn't want to fuck or be fucked by anyone else, though he didn't mind hand or blow jobs.

Harry didn't care as long as his mates were happy.

And it was good thing they did since a week after that talk Harry's mating season actually began. He started getting the urge to be penetrated, so he pounced on the boys one at a time. First was Ron - Harry's preferred mate. Then was Dean since Harry caught him in the shower, and though his cock kept bumping up against the ovipositor, they were both careful not to penetrate it. Then came Neville who he liked having on top since he was such an enthusiastic lover. By then, Harry was less wary about things, and having his ovipositor penetrated while it was still inside his slit made him see stars. Neville did pull out and come all over Harry's belly rather than inside him, so one of them was being properly cautious.

Then finally Harry pounced on Seamus while Seamus was napping and kissed him awake before he bit him. Out of all of them, Seamus was the least cautious person. When he found out that getting his cock inside of Harry's ovipositor felt wonderful for the both of them, he fucked it long and hard until he was coming inside of it and some of the itchiness abated.

When they realized what they had done, they admitted it to the other three boys. Figuring it was a bit too late to worry about it now, the other three decided they also wanted to try. One by one they fucked Harry into the mattress while the others watched or playing games waiting for their turn, and they all loved reversing the roles where Harry normally dominated so much that each one went at least two rounds. Harry was filled with so much come that he felt bloated, and when he checked his ovipositor because it was so sore, he saw that it had swollen itself shut and none of the come was able to escape.

The next few days was a nice break of no sex for all of them. Harry was a bit too sore for it, and the other boys knew they needed to prepare because Professor McGonagall had told them that it would be a days long marathon so food and water would be regularly sent to the room by the house elves, and the doors would be sealed from the inside so that nobody but them five could open it once they were done. The last thing she wanted was for anyone else in the house to intrude on their mating since Harry would either drag them in or attack them, and since the boys had already established their own rapport, it was best to keep it that way.

When the time came, Harry laid eggs in every one of them as he fucked them over and over again. He only laid three or four at a time, and when their bellies adjusted, he somehow knew that he could add more and when he should add them. By the end of the three days, each boy had at least fifteen eggs in them, and they looked very pregnant. Madam Pomphrey checked all of their healths after that, and learned that they all actually were pregnant and the ICW would have to be contacted to send a naga over so they could all figure out what to do.

The naga that was sent was very handsome even in his human form. He was taller and his shoulders were broader than Harry's, and he had traditionally long hair that he kept braided back. His skin was caramel and his eyes were slanted, and he had a decorative tilac on his brow that almost looked like a Fleur-de-lis. He wore bright silks and had a sword at his hip, and he was hands down the coolest person Harry had ever seen.

He told all the worried boys that at best, only one of the eggs in each of them would grow while the rest would be absorbed into that one egg for nutrition. He said that they were so young though that they would be lucky to get the egg to term, especially in the cold climate of Scotland. He told them to expect to absorb the eggs within six months, then he taught them all a charm that allowed waste to go past the eggs so they no longer had to rely on the mediwitch to cast a careful banishing charm on them once a day.

Then he chided Harry for not taking proper care to at least use a condom, taught him birth control spells that killed off sperm and potions specifically meant for nagas, then told him he did a very good job in picking out some mates and to be more careful in the future. He also invited Harry to Cambodia to the colony there to see what a community was like, then he left at the end of the day saying that Scotland was way too cold for him.

However the naga interference didn't end there. When summer came around and death eater activity really picked up, warrior nagas from several countries swarmed in. Harry told them about horcruxes and how they would need to be destroyed, and the hunting and destruction of them was finished by August. Voldemort was found screaming orders to the handful of followers he had left in the Malfoy manor, and he was painfully killed by spears and tridents while the rest of the death eaters were beheaded if they were of-age. As such, death eaters like Malfoy, Crabbe, and Goyle were spared, but the ministry ended up expelling them from Hogwarts, snapped their wands, and sentenced them to five years in Azkaban each.

Harry was glad to attend his seventh year. It was the safest year yet. Only Dean was still pregnant, his belly heavy with a large egg that had grown, and Harry and the others couldn't help dote on him since none of them were sure who the second parent for the baby was. Sadly, he absorbed it at the nine month mark which left all of them sad, but they had been warned ahead of time.

The other four boys enjoyed being pregnant so much that when his mating season came around in March, they all took turns with his ovipositor again and he happily fucked fertile eggs into them. One of the potions that the other naga had taught him was specifically for abortions, so the boys enjoyed waddling around until the school year ended and they all graduated together.

Harry kept his word. He actually bought the Riddle manor, and he had it completely refurnished. The graves were dug up and relocated elsewhere, and then he hired some Japanese wixen to enchant his new home in such a way that both magic and electricity worked together. Dean wanted to be able to watch his football on the tellie and to have proper lights that allowed for drawing and painting rather than flickering candles and fireplaces, Seamus wanted electricity to work on the rum and brandy that he wanted to make, Ron got into computers and computer programming with his analytical mind, and Neville just wanted an indoor conservatory which he got. 

The five of them ended up going to Cambodia a few years later and they saw that raising baby naga was a community thing done by nagas too young or old to have children, but there was also a smattering of 'mates' from various pairings that also lent a helping hand. There was four mating groups in the community, too. They offered Harry and his group space there if they wished, and a decade later when the five of them wanted children but found the climate to be too unsuitable for breeding, they joined the community for a couple years and were able to take home two half-naga babies... and a second naga mate that had their own group of six that had meshed amazingly well with the five of them.

Unsurprisingly, it was Seamus who decided he was done first. After three decades of being with Harry, he still looked like he was in his early twenties and he wanted to get married to a witch and settle down. They were all sad to see him go. 

Then Neville took a break. He wanted a couple human children to carry on the Longbottom line, but he promised to return in a few years and to everyone's delight, he did with two children in tow. Dean and Ron stuck by Harry's side, though, and when another decade passed and they decided to move back to Cambodia for at least a few years, all of them went, and Harry would end up collecting two more wizards to add to the harem before all of them settled down more permanently.
