[Request] A little game for their exercise

Chisato and Takina are engaged in a training exercise with each other, with the stakes being that the loser has to do whatever the winner wants. Unfortunately for Takina, Chisato was especially on the ball today and was quickly able to get her restrained. She has her hands bound behind her back and her ankles bound together, and she's lying on the ground. Chisato has her socks in hand and is ready to lay claim to her prize.
