Ok, I’ll try to keep this short. Me and my girl have been together 6 years, we are now 24/23. She has a younger sister, smoking hot, who is staying with us during Christmas break from college. Long story short, this past Saturday we had a get together. A lot of alcohol, smoke, ECT. Her younger sister doesn’t much drink, smoke or party at all. Saturday I got her to smoke with me and from there she loosened up and begin to drink. Guests start leaving and the crowd dies down, my girl gets settled in bed and it’s just me , her sister, and her sisters bf. We smoke a little as we talk and drink then they go off to the guest bedroom where she is sleeping. I straightened up a few loose cups and swept before heading down the hall to use the bathroom. As I come out I’m met at the door by her drunk 19yo sister. She changed, her perky little nipples were hard and her tight shorts were gripping her body so well. As I say excuse me and try to pass she grabbed my hand and asked me to see how wet she was. I instantly began rubbing her as I stuck my tounge in her mouth. She pushed me back into the bathroom. She instantly gets on her knees and pulls my dick out and begins jerking it. She would lick it occasionally and spit on it but she never sucked it. After a few minutes I told her stop so I don’t bust so she tells me to eat her.. I kiss her as she stands up then proceeded to help her out her shorts and on to the kitchen sink. I know I looked at her p***y for at least a minute before I stuffed my face in it. I was trying to taste as deep and as much of her juices as I could. I ate her for probably 6-7 minutes before I couldn’t take it any more. I stood up and began to try to enter her. As soon as I got close she stopped me and said thanks that she just needed her p***y ate because her boyfriend didn’t feel like doing it. She must have seen the look on my face and told me she’d be rite back. After a couple minutes she comes back and tells me I can come play. Then kisses me and asks if I liked the way her mouth tasted. I’m nervous and excited and scared if getting caught but I needed this. So I follow her to the room. She guides me in, tells me to lay on the floor so she can sit on my face. As soon as the light came on all I see is her p***y on its way to my face and her bf standing over me and her. Once she puts it in my face I went with it and just ate her out. This goes on for a few seconds. I can hear her sucking him and dripping drool down to my chest. I feel her stop bobbing as she reaches down with slobber from her blowjob and rubs it over her p***y as she presses it back to my face. Then I feel her move to her knees as she brand my d*ck and begins stroking it. After a few seconds I see her bf come around and get on his knees over me to mount her. As I tried to push her off she takes me in her warm mouth and I lost control. I began eating her madly as he began to enter her from behind. He was bigger then me, not huge but enough to catch an eye or 2. As he’s f***ing her from behind pretty rough I’m trying to keep the rythm with my tongue as she’s stroking me. Next thing I know she’s soaking him and my face as she shutters and moans out. As he pulls out of her I kiss and lick her for a few minutes before she kisses my dick and jumps up to tend back to her boyfriend. I’m still super horny and need to bust but they are too focused on each other. I sneak off back to my bedroom and tried to accidentally wake up my fiance and possibly get some sex but she was out. I began stroking trying to process what just happened and get me when I hear the door creak. Her sister asks if I’m still awake as we quietly slide to the floor. She wispers to me that she wants to have sex with me now but to eat her first. As I think nothing of it I dive back in her. As I stuck my tongue in her she grabs my neck and pushes her boyfriend’s cum all into my mouth/tongue. At first the texture was strange but tasting the combination was amazing. I ate her until I couldn’t taste the sex anymore. The it was my turn. I slid in her pretty p***y as deep as I could and gave her all I had over the next 2 minutes before I unloaded in her. After I caught myself I cleaned her back up and she left to bed. Things have been normal the last 2 days until tonight her sister asked her if she new what a hotwife was and how she felt about cuckold relationship and said she thought it was hot. My girl of course frowned up and made a joke about her and her bf being that. All her sister could do was look at me and laugh.
