Try to cum for Mary

You look at the fat woman who is wanking you... she is not so attractive as the other girl, but she looks like she is dreaming to have a sex toy and not to squeeze your balls till they pop and you think that is better to be fucked forever by a unattractive woman that to be tortured.

While you think you feel a familiar sensation in your balls and understand you're about to cum as you hear Jayne's voice saying -

"10 seconds bitch... don't dare cum for this ugly whale"
