She wants to get fucked in class.

She whispers that she wants you in her, right then and there. You are taken back but she quickly leans over and squeezes your throbbing hard-on through your jeans.
“Please.” She says in her sweetest, most **** voice. You hate it when she does that, it makes you agree to almost anything. And sure enough, you nod your head slowly. She lets out a giggle of glee and lets go of your erection. It’s your turn to lean over and whisper in her ear.
“How are we going to?” She puts a finger to your lips and draws her chair closer to yours. As inconspicious as possible, she puts her hand by your crotch and undoes your zipper. Using only one hand, she reaches into your boxers and pulls out your dick. She stops abruptly and looks around to ensure that no one is watching, you do the same. Getting caught would be terrifying. The teacher was busy giving a lecture on molecules and compounds, something she seemed to relish in, so there was no chance she’d be paying attention to virtually anything the students were doing. Most of the class would be asleep in four minutes anyway. As she turns to the blackboard, to write some definitions down, Kiki makes her move. In a fluid motion, she stands up, lifts her skirt, moves over to your chair and straddles you. As she lowers herself on to your dick, you reach your hand around her waist and grab her own. You feel your cock penetrate her ass, slowly injecting into her. Then, she puts her full wieght onto you, ramming you cock completely into her. She moans, almost too loudly, but no one hears her.
