Dirty 1st Person Imagines

Maths (Harrison Osterfield)

I and Harrison are not exactly fond of each other in school, but all of that could be about to change...
I was sat next to Harrison in maths, and was hornier than I thought possible. My cock would just not calm down, it was rock hard and causing me serious concentration problems. I suddenly felt a hand on my thigh: Harrison's. I looked at him maliciously and said "What are you doing?"
He replied "You might wanna be a bit nicer, I am gonna help you out with your little 'problem'"
"Because you're totally not tricking me"
"I'm not! Do you think I want anyone to know I'm touching your thigh right now?" He had a point, but I was still on edge. "No one finds out, yeah?" That sold it, he was serious, I could tell in his eyes so I shook my head and moved his hand onto my crotch. He smirked and undid the zip slowly: teasing me. Once it was undone, he stuck his hand in my trousers - but not my boxers - to feel my hard-on. He whispered in my ear "You're big" and I thanked him. All of a sudden he shoved his hand down my pants, grasping my erection tightly. He started to move agonisingly slowly, jerking his hand up and down roughly- right down to the base and straight up to the tip. He picked up the speed until he was wanking me off at the speed of light under the table. I was getting close so I grabbed his wrist for him to stop. He just stared at me and kept going faster and rougher until I was lightly panting. Finally, I came in my boxers, he pulled his hand out (luckily no cum was on it as that would have been hard to explain to everyone) and looked at me as I recovered. I thanked him again before he gave me a slip of paper with his number on it and said "If you ever have that problem again, call me"
"Don't you hate me?" I replied.
"Kinda, but that just makes me hornier for you" he told me nonchalantly.
