I always thought your girlfriend was too hot for you.  She’s out of your league, and as is now obvious, you are not enough of a man to satisfy a hot girl like her.  I think I’ll take her out tonight.  Once she sees this photo of you, servicing a real man, I am sure she will be available.

Tonight, when you are home alone, jerking off to the memory of my cock shooting its load into your throat, You can imagine me sliding my thick meat into your former girlfriend’s previously unsatisfied cunt.  Picture me riding her hard and deep, causing her to orgasm with pleasure.  I want you to jerk off and cum to the thought of me fucking your girl.

Later, when you see us on campus, you will both know that she is getting the cock that you want.
