Your girlfriend controls your cock. She has very strict rules, one of which is no cumming or jerking off without her. So when she finds a puddle of cum on the bathroom floor, she has an idea of what you need to do to make it up to her. From now on, you have to EAT your own cum. Pre cum included. And you're going to do this for me in a very specific position. And you'll do it, because look at me.... you should feel so lucky to cum for me at all. Yeah, you'll eat every drop then, won't you? ;) There's a special surprise in it for you, too...
