So one Friday night my buddy (Mike) wanted to go out for some drinks and go clubbing, his GF (Jess) was going to be there so I asked my stepsis (Nat) if she wanted to come as well since they were good friends. She agreed and after a few pre drinks at the pub we headed into the nightclub district and partied hard.
Most of the night was a blur but I remember my buddy saying how much he wanted to fuck Nat that night. It was a hot night and she was wearing a really slutty white summer dress with only a thong and no bra. For a size 8, dark skin, tall brunette she can really pull that look off and i remember thinking the same thing. Later that night, about 3am we came back to my place since i live closest to the city. We opened a couple more drinks and sat around talking.
After a while the girls went to sleep. Nat took my bed and Jess the spare room, while me and Mike said we would sleep on the couches. After about 30min Mike kept talking about how much he wanted to fuck my sis. I was pretty drunk so I told him I would too if I had the chance. What happened next i could have never predicted but he asked if I've ever wanted to see his GF naked, I never liked her much as a person but she was also pretty hot so i said I do but since they are together I wasn't going to try. His response was "She doesn't have to know about it" and "She's drunk enough to know". I was shocked but also had a tingling in my cock and instantly knew that I needed to stop thinking with my brain and use my dick instead. We looked at each other and knew that we were both thinking the same thing.
We walked over to the spare room where she was sleeping and Mike slowly opened the door to see if Jess was asleep. She was totally out of it so we walked in and and saw she must have passed out half way through getting undressed as her bra was on the ground and she was under the cover only wearing her skirt. We didnt do much to her as just being there with our boners bulging through our pants and gently touching her ass and perky tits, we were both scared shitless at the thought of her waking up and seeing us there.
This only lasted a few minutes, we took some pictures and I told mike a was going to go jerk off in the shower and go to bed.
When i came out Mike was in bed with Jess and I went to sleep on the couch. I was asleep for about 30min when cop sirens started going off a few houses away and all of us woke up and since we were all woken so suddenly none of us could go back to sleep. I guess I got lucky because if those sirens went off while we were still groping Jess or if we had decided to go further, I would have been in deep shit! We thought fuck it and decided to have a few more drinks to help us go back to sleep. The four of us sat on the couches and kept drinking until like 9 or 10 in the morning, Nat eventually decided to sleep with the help of pills. She pulled a bottle of xanax out of her bag, offered some to everyone but only her and Jess took some. Me and Mike didnt take any because we both knew that this was an opportunity to continue what we had started the night before. We waited about 45min while talking excitedly about our chance to undress Jess while she slept. She had passed out on the couch while Nat went back to bed. Mike proceded to slowly kiss Jess, shake her and put his finger in her mouth to get absolutly no response other than some quiet snoring. I took off her blanket and we rolled her onto her back. She was only wearing panties and a shirt so Mike proceded to take off her top with no troubles, her tits were perfect, not big but not small either, so perky and cute little pink nipples. He said go ahead and touch them so I did, and then couldnt help myself and started licking her perfect pink nipples. He laughed and put his finger back in her mouth as she opened it slightly from me playing with her tits. I my boner was about to explode so I told him i really wanted to fuck her now to which he responded "If i can fuck your sister you can". At that point i didnt care and even thought I could watch him as I thought my step sister was super hot anyway. I agreed and started to move my hand down her belly and under her panties to feel her already wet pussy. I started slowly with one finger playing with her clit and slowly fingering her, then two fingers. Her pussy was so tight I didnt think i could fit my cock inside her. After a few minutes we switched, he took off her panties and started eating her pussy while i started fingering her mouth to get her to taste her pussy juices. That and being eaten out must have sparked some sort of dream for her because she started slowly sucking on my finger and moving her head up and down. Being given premission to do what i want, i thought fuck it and took my pants off and gently pressed my cock against her lips. She reacted to it and opened her mouth and started sucking my dick. Mike saw what i was doing so he took his dick out and started slowly fucking her pussy, I could see he was going deep but not fast enough to accidentally wake her. It wasnt long before I felt a huge cumshot building up so I said we should switch.
She was laying on her side and instanly begun searching for a cock by moving her head around as i pulled out and went to lift up her leg to see her pussy opened up and dripping wet from Mikes cock. I rubbed my dick against her clit and I could see her moving her hips trying to get my dick to slip in and moving her head back and forth while Mike stood there letting her do all the work. I was ready to cum. I pulled out, got mike to step aside, he must have thought I was going to cum on her face as he was shocked when i stuck my dick as far down her throat as i could and let out a huge load. Instantly she coughed and cum cum splattered out of her mouth. As i pulled out I heard Mike saying she hated tasting cum which gabe me a huge rush. Cum was dripping out of her mouth and down her cheek as she tried to swallow and move her mouth around obviusly not understanding what was going on. I cleaned my self up and Mike got in his last few pumps before cumming on her tits. We cleaned her up, put her panties back on and covered her with her blanket knowing she had no idea what happened, cracked open another beer and sat down.
After a few minutes Mike said I better hold up my part of the deal and me being slightly horny i thaught, fuck it why not do it now. We were already only wearing our underwear and walked over to my bedroom where Nat was aleep. She was only wearing her thong. It was already pretty warm by that time of day and she must have kicked off her blanket so walkinig into my room to see her laying accross the bed on her stomach, her ass pointing at the door for us to see was the best sight in my life. She is my step sister so i didnt really have an interest in her but she looked so hot just laying there, ready for the taking, my dick got instantly hard. I told mike to go ahead and do what he wants. I only wanted to watch. He started smelling her ass and kissing her shoulders while rubbing her pussy through her thong from behind. She didnt even stir, she was so out of it she didnt even make a sound. He reached over and rubbed her tits but after a moment he said thanks but he couldnt get hard after Jess and was too tired to try again. I told him no worries and to go to bed while I get a change of clothes out of my wardrobe.
He left and so did I but after about 15min Mike was already asleep and I was still horny. I thought maybe i could just go to my room, look and Nat and jerk off a little. I walked in and her perfect ass was still staring me directly in the face. I couldnt control myself and instantly took off my pants and walked over to her and felt her ass. It was perfect! i couldnt just leave it there and i saw she was a little wet through her thong, probably from mike rubbing her so i pulled her thong to the side and started rubbing her pussy. Her pussy was amazing, even better and tighter than Jess's. I pulled down the thong and started eating her out from behind. occasionally licking her asshole while fingering her pussy. Pretty shortly I got a response from her and she started to move her hips and gently moaned as I licked her pussy. I rubbed her asshole with a finger and used her creamy pussy juices to lubricate it enough to slip my index finger in. She must have loved it because she let out a loud moan and started to roll over. I thought she was waking up so jumped off her and was ready to run out of my room but she wasnt awake. She was rocking her hips still asleep and moaning. I walked back over, my dick throbbing and saw her perfect C cup breasts with these amazing brown nipples. I started to lick them and bite them a little while trying to put my finger in her mouth with one hand and rubbing her pussy with the other. It took a little work but she opened her mouth and my finger slipped in to feel her tongue licking it in circles. I took my other finger out of her pussy and put it in her mouth to let her taste her own pussy, to which she moaned and sucked harder. I climbed on top of her and tried to fuck her tits, they were a little too small so i though i blowjob will be better anyway. I rubbed my dick on her lips and let her slowly move her head up and down. I had to fuck her. I pulled out of her mouth and spread her legs to feel my dick slip straight into this tight, wet, hot pussy. I started slow but I could tell she wanted more due to her rocking her hips so much so I though to myself, Im going all in or nothing at all. I fucked her hard for a few more minutes, she was almost screaming in her sleep. I then took my dick out of her pussy, stuck it deep back in her mouth, let her deepthroat me some more to let that thick spit build up on my cock and in her mouth. Then I pulled out, rolled her over quickly used my fingers to get some spit from her mouth and rub her butthole until it was nice and wet. I rubbed my dick against it and slowly pushed in making her moan like crazy and lift her hips to make me go deeper in. I had fucked all of my step sisters holes and after a few minutes of fucking that amazing tight ass I was ready to cum. I didnt want cum in her ass because it would have been hard to clean up so I pulled out and came another huge load over her ass and back. I thought that was it and that I was completly satisfied but as i was cleaning myself and her up i got hard again just thinking about what i had done and her pussy was still wet so i rolled her over and let her suck me off until I came in her mouth. The best thing was, she actually smiled at me when I pulled my dick out of her mouth and swallowed my cum. It wasnt as much as the previous two but that was amazing anyway. I left the room and went to sleep after that. The next day the girls had no idea what happened and me and Mike didnt speak a word of what happened.
