I have only had sex in the same room with someone else having sex once. When I lived in the dorms my sophomore year of college my roommate and I both had girlfriends at the time. We were horny 21 year olds, so we were each having a lot of sex. He was kind of an asshole in general, looking back on it, but was a fun guy to live with. I walked in on him fucking several times and he walked in on me once or twice. He was a big guy, and had one of the thickest cocks I have seen to this day, with a big purple head, and he was hairy as a beast all over. He was one of those guys who didn't give a shit about being naked, or walking in on him jacking off. He didn't flaunt it exactly, but he would just keep going and cum, even if you were in the room. He was kind of a perv, but I have to credit him for teaching me to be comfortable in my nakedness around other dudes. (I wonder if he is on this site?) We compared a few times, I was longer, but he had a beer can for a cock.
One night we both had our girlfriends sleeping over and I heard quiet moaning coming from his bed. I looked over and saw him mounting his gf. His bed was right by the window, and about 3 feet away from mine in that small dorm room. I was instantly rock hard. I reached my hand down to my girlfriends pussy, and it was dripping wet. She was awake, and horny too! I took my whole forearm and started to rub her. I pinched her nipple, looking for a reaction, and she let out a little scream. It was on! We all knew everyone was awake and we all started fucking. Eventually Kyle flipped on the lamp by his bed, the bastard, but no one said anything and we fucked in our respective beds, getting louder and harder. It definitely felt like a competition between me and him. I am sure he wanted to be the one to make their gf scream the loudest, I know I did. That made the whole thing seem extra charged.
At one point I looked over and Kyle was watching me, as he was fucking his gf doggy style, holding her head down. He and I made this crazy strong eye contact for a long time as we were both balls deep in pussy. It was almost animal-like. We watched each other fuck, giving the other permission to take it all in. Watching as the other was going in and out, in and out, in and out and started to move in rhythm with one another as we fucked. It wasn't like we were fucking each other, but it was almost like we were DPing the same girl, if that makes sense. He was giving me this cold gorilla stair, but I think he was also crazy turned on in this hypersexual way. I know I was. I think this whole thing was his plan all along. The kinky bastard!
Eventually Kyle came. He shot a thick load all over her back, I was still fucking my gf, but I slowed my rhythm to watch it go down. Watching him cum, in a way that really felt like he was cumming for me to see, made me start to go over the edge. I looked over and kyle just gave me the most devilish smile. right then and there I came inside my gf. I wish I could have pulled out to show him the huge load I was sinking deep into her.
Nothing was said and everyone passed out. Some time in the night showers were taken. When I woke up in the morning Megan was getting out of my bed. I pretended to be asleep, I didn't want to hear about what she thought of the nights events just yet. When it was just me and Kyle in the room I got up, not bothering to put on my boxers at this point. Kyle got up, naked too, and honest-to-god hi fived me! haha. From then on he would always tell people I was his brother at parties, but never mentioned the actual act again.
That was the only time I have ever fucked while someone else in the room, and not have it be a threesome. Everyone was doing their own thing. It was hot though, I would love to do it again.
