Breathe when I say JOI

Take a deep breath, you will need it! Haha! I wanna play a jerk off breathing game with you. The rules are very simple - when you breathe you can't stroke. When you stroke, you can't breathe. Don't worry, I will tell you what to do and when. I will even let you cum if you obey and deserve it. Have fun, wanker, and try not to pass out during this stroking game!
