Go to the back of class

You decide to head to the back of the class, perhaps foolishly thinking that less attention from the teacher and others could mean an easier go of it. As you walked through the students, you could smell the heavy scent of sex, sweat, and cum. Most of the Futa students seemed to be ignoring those either riding their cocks or sucking below the desk, as if it was their natural state

You reached the back row, and go a good look at the punkish student. She had black tape as Xs over her nipples, and wore a leather chest harness around her impressive assists. Her rocker boots snapped up just below her knees, and she was proudly bare ass and cock on her seat. You gulped before asking “um... can I share?”

“Mmmm” she looked at you like a tasty meal, “your pretty brave to come back here. Why don’t you climb up on mommas lap, and if you do a good job I might not break you for fun.”

She pats her lap, lifting her hard cock straight up for you to impale yourself with. You remember you chose this game, and there was no getting out of it until the day was complete. Sliding off your panties, you hand it to her before climbing over her lap and trying to lower yourself.
