My first time fucking in the library study room with my professor watching

Okay I still can’t believe this actually happened but holy fuck I’m wet just typing it. So I was in the library late at night cramming for exams and this older grad student (27M) who I’ve always lowkey thought was hot asked if I wanted to share his private study room. I said yes because honestly I was bored and horny as hell.

We’re supposed to be reading but we’re sitting close, our thighs brushing, and he keeps leaning over me to “help” me with notes. His hand slides down my leg and I don’t stop him. Next thing I know, he’s pulling me onto his lap, whispering that I’ve been distracting him all semester with my short skirts. My pussy was already dripping and I didn’t even care where we were.

He pushed my panties to the side and slid into me right there on the squeaky chair, my legs shaking while I bit into his shoulder to keep from moaning too loud. I swear I was cumming in under a minute from how thick he felt stretching me out. Then I realized—our professor was across the glass panel of the room, pretending to work but his eyes glued on us.

Instead of stopping, the guy fucked me harder. He spread me open on his lap, making sure the prof could see every inch of his cock disappearing inside me. I was shaking so bad from cumming again that I actually squirted all over his jeans, soaking the chair. He just grinned and kept going, making me his little slut while our professor sat there watching.

When he finally pulled out and came all over my stomach, I looked up and saw the professor’s hand moving under his desk. I came harder knowing he’d been jerking off to us the whole time.

I’m still thinking about it every time I go back to the library.
