Demonstration

You walk up to her at her desk. She bends over and shows her amazing ass to the class, as she pulls down her pants.

"Please be gentle on my ass today..." she says

"Don't worry. I'm not aiming for your ass" You say as you push your dick into her vagina. She moans so loudly as she feels you enter her. You begin to thrust into her and she puts a leg on a chair to spread her vagina even more.

"Oh fuck yes! Harder John" She moans as she places her hand on the back of your neck and pulls you closer. You are in the standing doggy position with her legs spread wide open. You pull out your dick from her vagina and she gets on her knees thinking that you are going to cum but you pick her up by her legs and start fucking her whilst holding her up off of the floor by her knees and she has her hands around your neck. She is constantly moaning and cumming and you feel yourself about to cum.

"I'm gonna cum inside you" you moan

"Please do it... It will be good for the demo... cum inside my dripping wet pussy!" She moans and you put everything you have into the final three thrusts and on the final one, you push your dick so far into her that your pelvis is touching her and release your hot sperm inside her. When you pull your dick out, all all of your cum starts overflowing out of her pussy. You put her down and she reaches to the side to get some tissue to clean up her vagina.

You go back to your seat class. “See Class, that’s how you have sex!” She says out of breath.
