Use Stella

I was preoccupied last time, but there was no reason not to use her now. I waited until everyone was gone except me and her. I then walked up to her.

"Alright, you asked for it. Lay down."

"Hmmm.... Finally, a man."

She did as I said and laid on her back on top of the teacher's desk. I took out my cock, and hesitantly inserted it in her exposed cunt. I shoved it in slowly, until I was balls deep. Afterwards, I started moving my hips back and forth, gradually increasing my speed. She looked pretty satisfied. When I couldn't take it anymore, I pulled out and came all over her naked body. She was still on her back when I started to leave.

"You ok?"

"Aha. Though, I wished you would go a bit harder."

I decided to keep that mind.
