I originally posted this story at the PicHunter forum, but somebody hear saw it and told me I should post it here. So here goes... I live in a two story townhome with a finished basement. When I first moved in I had a choice between the second bedroom upstairs, or the finished basement. I decided to take the basement for a number of reasons, such as privacy, proximity to the laundry room, and it was much darker due to not having any windows. One day I was downstairs while my roommate and her girlfriend (yes... my room mate is a lesbian) were watching television in the living room upstairs on the first floor. I got along with them just fine, but they were watching some show I had no interest in, so I went downstairs to my room to watch something else. I was surfing the internet on my computer while the tv was on, and came across a picture of a very hot girl. The pic got my mind racing, and caused a little more blood to pump into my crotch. Now, normally, I would go with that feeling and look up some porn to jerk off to. However, I had second thoughts since there was company just upstairs. I tried to let it go, but the picture of that hot woman kept popping back into my head. The girls upstairs were laughing and seemed to be into their show, and the only reason my room mate ever came downstairs was for laundry, so I said "fuck it" and logged onto my go-to porn video website. I'm not sure what type of porn I was watching, but it didn't take long for my cock to get hard. The picture of the hot chick from before was still in my head, then there was the porn that I was currently looking at, and finally the fact that there were people not far from me, helped speed things up. Although it had never happened, the idea of being watched was a turn on. At this point I should point out that while my room mate is not your typical hot chick, nor is she a lipstick lesbian like you see in most porn, she's not ugly in the least. She's a little over five feet tall, has a nice athletic build, and a really nice pair of tits (she showed them to me after we'd had a few drinks one night). As for her girlfriend she was more attractive, partly due to being taller and thinner, but also she had a goth look to her too. Her only downside was being pretty flat-chested. Anyway, I was starting to enjoy my masturbation session. My cock was really hard in my hand, and I was taking things slowly so as not to cum too fast. But I was too into myself and didn't know that I was no longer alone. "Enjoying yourself?" It was Brittany, and right by her side was her girlfriend Jenn. I didn't know how to react. There was no point in quickly pulling up my pants and pretending nothing was going on, as it was pretty clear what I was doing. After all, everybody masturbates, so there was no need to be embarassed. I just stopped the video on my computer. "I'm sorry, I thought you two were enjoying your show," I said. "We were, but the volume on your computer was loud enough that we could hear it. Sounded like something I wanted to see," replied Brittany. I finally started to put my shorts back on, but Britt (I have a tendancy to shorten everybody's name) interrupted... "No, go ahead and finish. I know what it's like to get started and then stop." "I'm not sure I'll be able to now, but go back to your show and maybe I will continue later." "But I want to watch. Just because I'm gay doesn't mean I'm not curious," Britt said. "You want to watch me jack off?" "Yeah. What do you think, Jenn?" Jenn just smiled and nodded her head. "Well, I've never had an audience before, but I think I can manage." With that said Britt and Jenn came all the way downstairs and sat together in a chair on the other side of the room, with a good view of what was to come. I restarted the video and immediately my dick got hard again. As weird as it was that my room mate and her girlfriend were right there, it was also pretty fucking hot. Like I said... having an audience was a turn on. I was slowly jerking off, as I wanted to prolong things as long as I could, but quickly I could feel the tension build up in my balls so I stopped. "Why'd you stop?," asked Britt. "I could feel myself getting close to cumming, but I didn't want to. At least not yet." "I thought cumming was the whole point. I mean, it's my goal when I do it." "True, but I'm liking the situation, and I don't want it to end fast. Although I'm not sure you're enjoying watching, anyway." "Oh, I am. What about you, Jenn? Do you like?" Jenn finally spoke, "absolutely. I've had sex with men before, so seeing a cock again is getting me so hot." Britt smiled and spun around on Jenn's lap and started kissing her. The whole situation must have really turned Britt on as well, because it wasn't long until a more innocent kiss turned into a very passionate one. Jenn responded in kind, and started playing with Britt's breasts. I started touching myself again, doing things such as cupping my balls, but making sure not to stroke my cock to avoid cumming right away. Pretty soon Britt and Jenn seemed to forget I was there, because Jenn ripped Britt's shirt off and started kissing and licking her big tits (Brittany rarely wore a bra). Britt started moaning in response before peeling Jenn's shirt off too. Thankfully Jenn wasn't one for wearing bras either, and I was pleasantly surprised to see that while she wasn't as full breasted as Britt, Jenn did have a nice small pair of tits. Jenn looked towards me, "do you like watching us instead of your porn?" "Hell yeah." Jenn smiled back as Britt turned and also gave me a smile. Before Britt could turn around and continue the kissing, Jenn told her to stand up. Once Britt was standing in front of her, Jenn started taking Britt's pants off. I was in heaven, and hard as a diamond. There was no way I could last much longer, regardless of whether or not I even touched myself. Down came Britt's pants, and I was in view of her tight ass barely covered by black thong panties. But the panties weren't there for long at all as Jenn pulled them down, before spinning Britt around and making her sit in the chair. At this point Jenn started to kiss and lick her way down to Britt's clean-shaven pussy, before eating her out. I was doing everything I could think of to keep from spewing my jizz all over the place. Looking at the walls of my room, thinking of anything but sex and girls, but it was no use. As much as I wanted this entire experience to go on forever, I just had to cum. As I started stroking my hard dick again I heard Britt scream in ecstacy, as Jenn had made brought her to orgasm in no time at all. "I'm going to join you, Britt. I'm about to cum!" Britt and Jenn looked my way, and my eyes met theres just as jets of my thick, milky, cum started shooting out... all over my stomach. "You're turn, Jenn." Brittany made Jenn stand up before removing her pants and panties as well, and then had her sit in the chair while Brittany started to eat her out. Although I had finished I kept watching, and a couple minutes later I started to get erect again.
