Show him, of course!

You grab Joe by the ass, and pull him close. He starts to object, but you start to take his shorts off, and he suddenly realizes what he had asked for.

"uh.... thats not what I meant..."

You've already got a hand in his shorts, his pants down to his ankles, but you ask anyway, "want me to stop?"

"Unhgh... " Joe groans, unable to make up his mind, as his cock is fondled for the first time in his life.

You stroke his small cock a few times, before popping the whole thing in your mouth. Its only a few inches long, even fully erect, so you have little problem.

"Holy shit, don't stop...ughn..." Is all Joe can say.

"I'm not going to stop.. but in return, after we are done, I want you to do something for me..." You say, and Joe looks down at you, as if he's wondering why you stopped sucking his cock to talk.

"What is it?" he says, anxious to get you back to sucking his cock.

"I want you to seduce Professor Garmon..." you say, smiling up at him. Professor Garmon is the grey haired science professor everyone on campus swears is gay, but no one has been able to prove yet. A few guys had even tried... but none of them were quite as nerdy and **** as Joe here is. "You know who he is, right?"

Joe nods at you.

"And you agree to this deal?" you say, and Joe quickly nods again. A picture in your mind of straight laced professor Garmon with his short grey hair and glasses bending Joe over on a desk and fucking him hard in the ass appears and you don't much mind when Joe pushes his dick against your lips.

You give him another good sucking, licking his balls, the space beside his balls, and up and down his shaft, before sucking his again, this time fondling his wet, slimy, balls. He moans and cums right as you are about to lick his balls again. Cum shoots all over your hair and you give Joe a sour look.

"You are going to have to suck my cock now, for that one..." you inform Joe, and he nods at you.

"Seems only fair..." Joe says as you slide your pants down, and pull your cock out of your boxers. Joe smiles a bit and starts to kiss your cock.
