He came again without telling me... damn, the guy is a fucking pig!!

He may be as dirty as you say he is but I'll tell you one thing, if you didn't want to turn him on you wouldn't take a nap and you would put your head in his crotch hehe, so I sincerely believe that what you did was to provoke the reaction he had so I think you wanted to suck him off and I think he also wanted him to cum in your mouth, right?
