My two roommates and I had a strange dynamic.
To give some background, Brian and I had become good friends since moving into the apartment 5 years ago when we were both 22 years old and when a three bedroom unit opened up next door, we decided we could save money by moving over to there and finding a third roommate. We met a few guys and girls off craigslist even though we weren't keen on living with a stranger but then one night at a bar as I was telling a friend about my situation, he mentioned he knew a girl who was looking in my area.
His friend's name was Kelly and we agreed that Brian and I would meet her for a drink the next night. When Kelly arrived at the bar, we saw a fairly attractive girl, not really my type as someone I would date but that wasn't the point; the point was to find a roommate we could get along with.
Kelly was also 27 years old, about 5'4'', somewhat overweight with long blonde hair and an average face. What did stand out was her tits, which appeared to be pretty big and were kind of popping out of her top. I wasn't sure if they looked big because she was a big girl in general or if they were just a pair of big tits. We had a pleasant conversation with her and she ended up moving it to our place the following week.
Brian and Kelly seemed to become better friends than Kelly and I which was fine because it wasn't like we were all home at the same time and it wasn't like Kelly and I hated each other. We just didn't have much in common, and I spent most of my time with my girlfriend.
While I never walked around the apartment in my boxers or underwear, Kelly would occasionally be in the common areas of our apartment in her boy shorts and a tank top with no bra. She would sometimes come out of the shower and Brian and I would see her in just a towel for the few seconds that she would walk from the bathroom to her bedroom. It was during these moments that I did take notice that those tit were pretty fucking big. Her legs were also kind of thick as was her ass. Again, I obviously didn't mind these glimpses but I was never very attracted or had any thoughts or interests in anything sexual ever happening with Kelly.
One night we got into an argument over one of the utility bills because she was using her air conditioner every night and I was not and I didn't think it was fair to pay the same amount. Brian stayed out of the argument and we ended up working something out but after that, Kelly and I didn't talk much. If I saw her car when I got home, I would sometimes try to come in and sneak into my room or I would walk around outside for a while just to avoid any interaction with Kelly. I knew she had started dating someone though because I heard her talking to Bri about it and I saw her posts on Facebook. I hadn't yet seen the guy at our place but I figured he must be an interesting guy to put up with her bullshit, which had gotten worse of late in regards to her leaving her stuff all over the apartment and being the typical slob roommate.
The more time that went by, the more I realized how self-centered and into herself Kelly was and I thought it was kind of funny because I didn't think she had reason to be based on her looks and her average job as a cashier. One particular night, I came home late from work and felt the immediate dread upon seeing Kelly's car but when I walked inside, the apartment was totally dark. I walked to the bathroom to take a piss and that's when I heard the clear moaning coming from Kelly's room. At first I thought it was maybe her tv but then I knew it was the unmistakable sound of her getting fucked, and fucked hard from the sound of it. I lingered in the bathroom doorway for a minute and listened to her getting plowed and begging for the cock to go deeper inside her. I assumed Brian wasn't home since his car wasn't outside and I guessed Kelly thought she had the place to herself, didn't know how loud she was, or just didn't care. I suspected the latter. But as I stood and listened, I couldn't help but start to get a hard on and my mind started to picture what the scene behind that door looked like.
I walked away and went back to my room and for the life of me could not get the image of Kelly getting fucked out of my head. I went on to her facebook page and started browsing her pictures, specifically the ones where she was in tight shirts or bikinis, which weren't plentiful but there were more than enough to excite my now throbbing hard cock, which was attempting to poke it's full 7 thick inches through my shorts. I couldn't hear them fucking anymore since my room was across the apartment but I must have jerked off two or three times to the thought of if that night. I didn't understand what was happening since I never found her attractive and barely spoke to her at all anymore, but there was something about the sounds she made and the thought of those big fucking tits bouncing as she begged for cock that made me start to see her differently.
