Bend her over the desk

What better way to fuck a teacher than on her own desk? You unzip your jeans and direct her to bend over on the desk.

You kneel down and thumb her clit, moving your thumb in a circle around it. She starts moaning and her juices are dripping from her pussy onto the floor. You figure she doesn't need more foreplay.

You stand up and take out your cock. You plung it in to her wet folds without any warning.

"Ohh Nick!" She cries out. "You're so much bigger than my husband! I'm so close, just keep going!"

You have at it, thrusting faster and faster. You reach down and mercilessly grope her breasts, earning a moan of pleasure in return.

All of a sudden, her walls clench up and she starts gushing in orgasm. You're getting pretty close too. Where do you put it?
