An uninterrupted fuck.

Kiki starts to slowly work her body up and down on your dick. You are amazed at just how tight her ass is. You feel as if your wearing a full length cock ring a size to small for your dick. Your trying desperately to resist the urge to cum on the spot. She gets a rhythm going and soon she is bouncing full speed . You hold tightly onto her hips so she doesn’t bounce right off your dick. She begins to moan, not loud enough to disturb the rest of the class, but you move a hand up to her mouth anyway. With your other hand, you slowly start to jerk her swollen cock. For a moment you are slightly jealous of the fact that your cock, while an impressive eight inches, is outstripped by her eleven incher. One hand barely fits around it, so you move your right hand away from her mouth and start to work her member with both. She is getting off on this and before you can object, she starts to unbutton her blouse. You thank the gods that the teacher is oblivious to anything around her accept her lecture as Kiki begins to work her breasts with both hands. Finally, you feel yourself ready to cum, so you reluctantly let go of her dick. Instead, you grab her waist with both hands, and give one almighty thrust into her as hard as you can. She lets out a squeal of pleasure and pain as you fill her ass with your warm sticky cum. You cum for almost ten seconds, pumping more and more of your seed into her stretched asshole. You feel you own cum dripping out of her ass and you nearly collapse in your seat. She is moaning in exhaustion and with one motion, she stands up, whipping all eight inches of you out of her ass in one shot. You get a very horny shot of her cum-filled ass as she returns to her seat. Moments later the bell rings and the two of you leave class. She can barely walk straight as the two of you walk down the hall, you notice cum dripping from under her skirt.
She looks at you with pure joy on her face. “That was awesome!” She says
“So what should we do next.”
It was lunch time so you had at least forty five free minutes. But before you can answer she says “I have an idea” and leads you into an empty hallway. She drags you by the arm into an empty girl’s room and locks the door.
“Now,” She says with burning anticipation “It’s my turn.”
