Chapter Text
Nemona and Mirko are naked and locked inside human-sized hamster wheels. Their arms are raised above their heads and cuffed to the sides of the wheel. They also have clamps on their nipples, tied with threads to the top of the wheel and pulling their breasts upward.
The wheel doesn't move, but under the girls there's a treadmill connected to dildos, which are inserted into their pussy and ass. The treadmill isn't automatic, and instead moves when someone runs on top of it, and its movement also makes the dildos go up and down. Whenever one of the treadmills stops, the door to the opposite girl's wheel opens and her restraints are unlocked.
The goal of the game is to keep running for longer than the opponent after the game starts. Once a girl escapes the wheel, she will advance to the next round. The restraints on the loser will get tighter, and the dildos will stay active automatically for 6 hours, and pump cum into them from a connected tank.
