Not proud, fucked my married step sister [mf]
So, I have shared a bunch of my personal sex stories, but due to the content, this was one required a throwaway screenname. What is interesting for me is that I now see that most of the things that spark me the most sexually began on this day: Panty/ass/pussy sniffing, pregnancy risk, being dominant, fucking married women, cheating, risky sex (where you could get caught easily). And this all happened with my step sister in the course of one day. This is really difficult for me to write because it is the sexual experience I am most ashamed of, but to this day the most intense sexual experience of my life.
My step sister, Allison, is 9 years older than me, we were not and still aren't particularly close probably due to the age gap, we never even really lived together. I always thought she was beautiful; truthfully she is one of those women that everyone thinks is beautiful-5'6, black hair, green eyes, a stickout ass, C-cups that sit perfect without a bra and she has always just oozed sexuality. She moved out at 18 for college and never really lived home again. She got married at 25 to a nice enough guy, they didn't have kids until much later and they lived a few hours away so we saw them mainly on holidays or special occasions. I was graduating high school and my dad decided to throw this huge party, which I thought was pretty ridiculous since it was just high school but whatever. Anyway, so after the ceremony we had a probably 75 people at the house for the celebration. Allison came in to town for the party with her husband and were going to stay at the house. When I returned from the ceremony, I was greeted warmly by family and friends and worked the room a bit when I ran into Allison, who gave me a big hug and kissed me directly on the lips. There were people fairly close by (including her husband and my girlfriend, Heather, but it was one of those quick 2 seconds kisses that honestly could have been harmless. But I was immediately thinking, "was her mouth opened", "her lips felt really moist", "what the fuck was that". Considering her husband, my girlfriend, BOTH OF OUR PARENTS, and a house full of people I decided that it didn't mean anything and she likely meant to kiss me on the cheek and accidentally caught me on the mouth.
The rest of the party was pretty normal shit; catered food, cake; some music and mingling. Eventually my girlfriend had to leave as her family wanted her home to celebrate, so I walked her out. I was pretty frustrated that she had to leave as we had a really active sex life- we had sex at least 5 days a week (her dad traveled a lot for work and a mom who worked nights), but we hadn't had sex in a few days, and my 18 year old balls were aching. Anyway, gave her a kiss and sent her on her way.
Back inside, it was dying down a bit, our parents (my dad is married to Allison's mom) were cleaning up and I went to help. I didn't see Dave (that's Allison's husband and by the way still is), he went upstairs to Allison's room after a bit too much to drink. Allison came down after helping Dave upstairs and it was all pretty normal. We talked about her job, my college plans, her new house, my girlfriend...all the normal shit you would talk to your step sister about. Eventually, our parents said goodnight to Allison and I and went upstairs, leaving us downstairs. It really wasn't too late, probably about 930 or so. She mentioned she didn't eat much at the party and asked if I wanted to keep her company while she grabbed something. I sat at the kitchen table while she grabbed some ice cream (she never really ate food-food, it was always snacks). Anyway, the conversation was mostly more of the same, innocent stuff like earlier but we talked briefly about my girlfriend, Heather. Allison asked if we were having sex; I told her the truth that we were and she didn't ask for many details but did remind me to use protection and not get her pregnant. Probably good advice. Allison said it had been a long day and she was going to go up to bed. We said goodnight- no kiss, not even a hug. Nothing. Now I knew that earlier was an innocent mistake and felt like a complete pervert for thinking sexual thoughts about my step sister. I went to my room, which is downstairs and heard her go up. Truthfully, I planned on closing my bedroom door and jerking off, and heading to bed...
I was just laying in bed watching tv when Allison appeared. My door was closed, but she hadn't knocked, and just walked in. Without saying a word, she just laid down in my bed and climbed on top of me and kissed me hard on the mouth. Now I knew that earlier wasn't a mistake, she meant to kiss me. We were making out and grinding hard-she was wearing sweat pants and a tank top. In one motion, she swung around into a 69, she was still wearing clothes, but pulled my shorts down and started to suck on my cock. Her ass, in the sweatpants was right over my face, and I tried to pull her pants down to get a taste and she told me no. So, she kept giving me head, rubbing my cock all over her face, and was tugging my nuts aggressively. Eventually, I was able to get her sweatpants off, but when i went to pull off her thong, she told me no. She said that I could smell her but I couldn't eat her. Well, I was 18, had my cock in my 27 year old step sister's mouth, and her perfect, thong covered ass in my face. She started to rub her thong covered asshole, all over my face, grinding it into my face. I could smell the heat coming from her pussy and I could smell sex coming from her pussy and ass. Not to be gross, but i just love the smell of a woman. Her pussy. Her ass. All of it. Since my first time eating a girl out, I have always had a thing for licking their asshole too; don't know why- probably just because I am a freak.
While the smell of her asshole and pussy was intoxicating; I was truly drunk off of it, but I had to taste it. So, I just started licking up and down her ass crack, and trying to lick her asshole- but just couldnt get to it. I was licking her asshole through her thong. So I moved my mouth to her thong (completely soaked) and started eating her pussy through her panties, even tongue fucking her with her own panties. And as for the blow job, she did a lot of teasing and less sucking which was smart because I would have cum. Back to the panty pussy eating- Allison pulled her own panties off and mumbled fuck it, and grabbed me by my ears and shoved my face into her pussy while she fell back onto the bed. To this day, I have never tasted a sweeter pussy. I knew it was wrong. I had a girlfriend, she had a HUSBAND, and oh yeah, my DAD is (still) married to her MOM. WTF. This was all going through my head while I was licking her ass and pussy. This may sound sick, but I actually LOVE the smell of a woman's asshole- there is just something so sexy (dirty) about it...I just couldn't stop. Eventually, she pulled me up by my cock and started to guide me into her saying in passing, "you can cum where you want, but I am not on birth control". She guided me in but kept her hand on the base of my cock so I couldn't sink all the way in. Maybe she thought my 18 year old dick wouldn't be able to take it and would cum in 30 seconds....She has to give me more credit than that. For like 20 seconds she kept her hand there, and honestly it was a good thing because she was really tight and I don't know if I would have had the patience to ease in....anyway, she finally moves her hand away which is about a minute in to me getting my cock into her, and I can finally sink all the way in, her pussy felt like it was milking my cock on every stroke, and oh fuck....shit......there was nothing I could do, I thrusted as deep as I could and I started to spew rope after rope of cum inside of her pussy. She had pussy control that I have never felt with someone else where her pussy felt like an actual hand opening and closing...it felt like I was getting jerked off but by her pussy. Her tight little pussy just kept spasming around my cock and i just kept shooting more. One of my favorite things ever is when I cum inside a woman is to watch all of my cum leak out and drip down her asshole; her pussy seemed to want to keep it all in, and then what seemed all at once it started to flow out, and it was A LOT. I will never forget looking down at my step sister's well pounded pussy, spread wide open, with all of my cum dripping out- while it was the best sex I ever had I also was thinking what the fuck did I just do.
