GFE Breath Play JOI Game

I thought we could do a different kind of training today, senpai. Especially since we're dating now! And since I always see you looking at me like your head is full of dirty thoughts, I thought it'd be fun to play a game. A game! Something that will help me figure out exactly what part of me turns you on the most... I think I already know, though haha. So, when I clap, you stroke. When I snap my fingers, you hold you breath. Easy, right? Oh, and no cheating! If you play fair I'll give you a reward. Sound good, senpai?
