I get home late one friday night a blind date stood me up. I expected my roommate to be gone at his girlfriend's house. So I would have the appartment all to myself. I could chill on the couch and just play xbox till I go to bed. But that is not what I come home too.

The light was on outside the appartment I put my key in the door and turn the handle and step inside and close the door I hear my roommate holler "oh fuck Tim I thought you wasn't coming into night." I flick the light on and say. "No I got stood up and, OH FUCK!" There he was naked as the day he was born laying on the couch, still balls deep in a girl on top of him. Her hands reach up try trying to cover her large breast. He was having sex on our couch but that wasn't his girlfriend. It was his girlfriend's sister, she had been over to the apartment with her sister a few times before. "What are you doing Stacy is gonna kill both of y'all." Becky stared at me wide eyed looks looks at me down at Mark then back to me. "You can't tell Becky please. She pleads with me. "I don't know I can lie for y'all." She looks panicked and says "wait what if we let you join in?" Mark looks at her surprised and says "Wait are you for real? Are you sure?" She nods and starts grinding on him. "Come on she don't have to know it can be our little secret, and it could make up for being stood up." She says seductively. I watch her hourglass figure bounce up and down on him, her eyes fixed on mine. I had always wanted to have sex with her. And it would make up for being stood up. "Ok let's do this" I replied. Mark grinned as he watched her ride him. Stacy reached back and grabbed her ass, she looked at me bit and rolled her lip. "Please tell me you have lube." I nod and say "I'll be right back." I rushed off to my room and come back with a bottle of lube I kept from from when a tender date said they wanted to try anal.

I got back to the living room and Becky was still riding Mark. She lookd over to me and gestured for me to come over. I stripped naked and walked over. "Let me see it be for you put it in my ass." She said as I got closer. I walked over next to them and she stopped bouncing on him, she leaned over and grips it in one hand and started rubbing and stroking it. As she jerked it Mark started playing with her breast. As she played with my dick and it got hard, soon she had to use both hands. She smiled and said "make sure to use a lot of lube on that thing." She let go and I got be hind her as she laid flat on mark. I made sure to use plenty of lube and then some. I positioned my self be hind her. It was a tight fit but felt so good. As I pushed my way in she let out a loud moan and I heard Mark hollar. "Hey Tim what the fuck wrong hole occupied bro." I looked down and seen I had missed her asshole, now both of us were in Becky's pussy. Imideatly said "shit my bad" and as I tried to pull out Becky tried to reach back and stop me while saying "please no I need this, fuck it fells so good." I looked over her shoulder at Mark and he nodded. I pushed my way in as deep as I could get. I could feel her pussy squeezing our dicks to geather and it felt more amazing than I would have ever expected. Becky slightly held her self up as both Mark and I started thrusting in her in different rhythms. Stacy moans turned to yells of extacy. I thought she couldn't get any tighter but her pussy was squeezing both of us even tighter as her entire body shakes as she came on both of us. I slowly pulled my cock out and put it in her tight ass as it slowly gave way to every inch of me she moaned loudly. I began thrusting back and forth as she moved in rythm with me. Soon I was all the way in her ass and something came over me I began pounding roughly in her ass she let out a cry of both pain and pleasure as I did. Soon mark called out "fuck let me out I'm about to cum." She shook her head no as she trapped him inside of her as she lowered her self I came down harder in her ass. I would feel his dick throbbing in her pussy. Soon I clutched her hips and shoved my dick as deep as it could get, as wave after wave of my cum filled her ass. I pulled my self out and fell backwards to the arm of the couch and watched as cum leaked from both of Becky's holes her ass gapped open from my pounding.

Breathless Mark said "what the fuck Becky what if I just got you pregnant." She sat up and said "relax I'm on the pill." She said equally out of breath. Wobbly she walked off to the bathroom. Mark looked at me and said "not a word to Stacy about this." I nodded and replied "Not a word."
