So, your roommate caught you

Sort of all got caught.

I was jerking off and mostly on top of the blanket. The door starts to open and I'm pulling at a blanket that won't reach up to cover little Mr.Happy, and I look up to see my roommate with his cock out being held by a topless girl he's making out with... the girl happened to be my girlfriend.

I knew exactly what they were planning on doing... but when they looked at me they knew exactly what I had been doing.
 
Indirectly. It was freshman year in a triple. Before either had awoke, I had cum in bed quietly into a wad of tissues (which I would always slide down the side of my bed against the wall for later disposal). We all got up soon thereafter. In preparation for my shower, I took of my underwear and threw it in my hamper. Our towels hung inside the door, so this involved walking naked across the room. Such incidental nudity was no big deal...we all did it. That particular morning, I was in the middle of talking with my roommates at the time, so I made normal eye contact, etc. When I got to my towel, I glanced down and noticed a large piece of tissue was stuck to the tip of my dick. They never said anything, but there's pretty much no way that they didn't see it and it's pretty obvious why it was there
 
My freshman year my roommate was supposed to be in class so I pulled down my khakis and boxer shorts and hopped onto my bed and started jerking it. Then I heard the door knob shaking so I quickly threw the blanket over myself and hid the tissues I was using. I was hoping he'd be quick and leave but he sat on his bed directly across from me and started watching TV. I laid there for as long as I could but eventually I had to go to class so I tried to pull up my boxers and pants without him noticing. I got my boxers up but as I moved my pants up, my belt kept making noises so I'm pretty sure he knew.

We never spoke of it
 
Hi guys! So interesting to read about your experiences. I can't remember I've been caught with my pants down and cock in hand. Well, been close a few times. Maybe just been lucky to have enough privacy. Even when I shared room with a schoolmate for 2 years I don't remember any close situation, even if I masturbated very often. At home I got own room before I started to shoot sperm. Several years I had only dry orgasms. My room was a pass through, but I could hear in time if somebody was coming to cover myself.
One reason to write here is also that I think it's a bit strange why it's so embarrassing to get caught with dick hard and masturbating. I mean at that young age all guys do it and often! It's the most natural thing. Of course I have to admit that I'm a bit shy too if somebody happen to see me wanking. Though at old age now I don't really give a shit. Of course I'm discrete not to embarrass other people.
