Biology

I arrived at my final class of the day. I entered the classroom, and immediately went into shock. There was a girl I knew all to well, naked and on top of my usual desk.

"Stella!?"

What is she doing here!?

"Oh, hi Barry! Didn't know you'd be here. Seems like today will be fun after all."

She explained that the teacher brought her to better showcase the human body. She was naked anyway, might as well make her useful I guess...

"It's been so boring! I am here 10 minutes with my bare, wet ass pointed towards every boy in the class, but no one came to use me. Could you, please? I haven't stopped thinking about how hard you pounded me yesterday. Make me yours again!"

Some of the guys started looking at me in a weird way upon hearing that.

"M-Maybe after class."

The teacher came in and started the lesson. Stella was next to the blackboard most of the time, letting the teacher touch her on various spots throughout the lesson. When the bell rung, she gave Stella a hard slap in the ass before letting her go.
