My dad goes and gets remarried when I was 16 years old. I have already accepted that there is no more mommy and daddy relationship and the fact that now my family was getting bigger weather I liked it or not it was growing after the marriage. My dad’s new wife or should I say my stepmother had one daughter named Nikki and a set of twin boys, Lance and Todd.

The getting to know our new family members period was moving quickly and my stepbrothers were easy to adjust to as they were 10 years old and could be occupied with a simple game or some candy. My stepmother was no problem as she seemed not to really want to play the mother role with me and that may have also had something to do with my attitude towards her from the start of her and my dad dating.

The only person I had a difficult time with adjusting to was her daughter and my stepsister Nikki. When they got married she was 14 and was to be truly honest a bitch most times I dealt with her throughout this adjustment period. There was alot of teasing and name calling between us two and it seemed as though we were just oil and water. This continued throughout the first 6 months and I didn’t see it getting any better.

The first summer we the new step family and I was determined to have a great summer no matter who was in my house. The young boys were set to go to tons of camps and school activities. My dad working crazy hours as usual and my stepmom was following suit with my dad working tons of hours. That left me stuck with my stepsister Nikki whom we just didn’t get along.

This one summer morning I had slept later then usual and was just rolling around in bed trying to get myself motivated to get out of bed. I hear a voice call my name and it sure surprised me as I hear my name being called aloud and I ignore it. Again i hear it and then it is followed with a knock on my door and it slides open and Nikki peeks her head in my door. Like clockwork I say to her, “bitch what you doing opening my door to my room?” as she replied back to me to shut the fuck up and she asked me if I was going to come swimming today. My smart-ass reply was “Nikki yeah but I don’t need you to go swimming so why you bothering me?”. She reacted with an unfamiliar look and quickly ran away from my room and I just laid there and figured to get myself moving and jumped out of bed. I knew I was going right into the pool I just throw on a pair of long basketball shorts and nothing else and headed downstairs. The one thing was that the way Nikki reacted earlier was on my mind today.

I go out to the backyard and Nikki is in the pool. I go and stand by the edge of the pool looking down into the pool and Nikki. I don’t know where it came from but I apologized to Nikki for being rude this morning and she half smiled back and said that she was use to it and was pouting. Where was this pouting coming from and it had an effect on me that is hard to explain. It made me feel bad and guilty for treating her like siblings usually act during their teen years.

I pulled up a chair and sat down and told Nikki that seriously I felt bad and let’s start being nice to each other at least for just the summer. This sent her face into a smile and it was a smile I haven’t seen before and it made me feel a little bit better. Nikki was continuing to swim around the pool and I was so focused on her feelings and reactions it slipped by me that Nikki had on a green bikini which was skimpier then I ever seen her wear and I actually started to notice how nice and tight of an ass she had as this bikini highlighted. She started to climb the steps out of the pool and now I could see that my step sister had a nice set of tits on her and the were perky and just covered enough in this suit but her nipples were erect from the tempature change i assume. With her hair being wet and she pushed it all back off her face her eyes were piercing to me as she walked towards me and surprisingly sat her round tight ass right on my bare right leg.

Nikki what are you doing there are chairs all over the place and you chose my leg. She turned into me and replied with remember we have all summer to be nice to each other so don’t blow it on Day 1. I reached forward to grab her hips with both hands and positioned her the way it was comfortable for me and we chatted for a few more minutes. Then I took a chance and asked her if she ever smoked pot and she told me yes as I offered her to get off my knee and head into the backyard shed where I had it stashed and that is where we both went to get some weed. I had some already prerolled into a joint so I grabbed the one joint and invited her up to my bedroom to smoke the joint.

We head into the house and upstairs to my bedroom. My worse nightmare happens as she went ahead of me up the stairs and I slowly walk behind my sister in a bikini checking out her tight little ass and imagining what her opening to her womanhood looks like and I am imagining it very specifically. So much that I walk right into her when I reach the top of the stairs as i was in my head not aware of us being at the top of the steps. Would Nikki catch on that maybe her brother is such a pervert that he is gawking and so focused on my ass that he didn’t even see me stop at the top of the steps. I say no no no to myself as we head into my bedroom thinking she has no idea… She can’t have any inkling that I am checking out her body…. CAN SHE?????

I close the door behind us and turn on the TV. I then go and open the one window so the smoke will go out of the house not that we need to worry as we have at least another six or seven hours until someone is home. I let the joint up and sit on my bed and inhale deeply…. As I exhale I invite Nikki to sit on my bed so I can hand her the joint and that she does and we end up knee on knee. I feel a little uncomfortable but also was distracted as I wanted to see how she smoked the joint which would tell me how experienced she is in smoking weed. She inhaled like a pro and we continued smoking the joint as after each hit we were more relaxed as the time before and as I was now aware our knees were carassing each other’s knee and leg.

A good twenty minutes of giggling and claiming how high we were and all our issues and relationship difficulties seemed to be out the window like the weed smoke was as well. Television was on and we talked about the show that was on for some time and then I found myself just gazing at Nikki and running my eyes up and down her body like she was a piece of meat. I was fixated on her bare feet that were nicely manicured and her toenails were painted. I reached down and grabbed her left foot and pulled it up to my lap which in turn shifted Nikki so she was leaning more on her back and facing me. I touched her toe ring and said, “Nikki I love that ring and I just think it is so cool” as she was wiggling or attempting to wiggle her foot away. I said why you doing that as she loudly said my feet are ticklish and I said with a smart ass smirk “oh your ticklish where here as I touched under her foot and that made her squirm harder trying to get away and I let her get away as I was too high to fight right now.

I felt like ten hours had passed as we both sat around and watched television and had small conversations, but we were up there for about two hours in reality. Somewhere in those two hours I began to look at Nikki in a sexual and caring way and ended up siting up against my headboard on my bed with her laying right next to me and she was resting her head on my bare chest. I slowly put my arm around my once bitchy bratty stepsister and pulled her into my chest in a comforting embrace. In a move that shocked both of us I instinctively leaned down and kissed her on the top of her head and continued light pecks down the side of her face searching out for Nikki’s lips.

Her skin tasted like a secret sweet desire mixed with chlorine and salty tastes as I searched for my desired body part of my stepsister. She followed along moving her head off of my chest allowing me to kiss down the side of her pretty face. I was feeling or sensing no resistance from my sister and this allowed me to continue as I was now searching to finally kiss those sexy lips of Nikki. I managed to position her off of my chest and maneuvered her so she was now between my spread wide legs and we were chest to chest. She looked up at her brother and we locked lips and we kept our eyes opened and I stared into those eyes of Nikki. Lip locked still I then parted my lips and took my tongue to her lips. I ran my moistened tongue over her lips from left to right encouraging her to open those lips and take my tongue into her. Four or five runs of the tongue finally she opened those lips and our tongues met and it was magically to me as I felt that feeling all the way down to my toes. We were going back and forth swapping our tongues into the others mouth and the excitement was growing from this forbidden play and Nikki reinforced that same feeling as she now moved herself further up my bare chest so we were closer then ever and could continue this hot AF makeout session.

The dilemma with her new positioning and with how hot she was making me was that how she was laying now she would feel any growth by my cock from her stomach and hip area. I was so into our kissing but was trying to be aware of my placement of my hands because even though I was already in forbidden areas did I want to go further. With all the passion I was feeling my hands went to her back and I started to run my nails lightly up and down her back. She had her left hand on my face and continued to carass my face as to tell me to continue this encounter. I continued to carass her back and now found myself going further down her back and actually slide my hand into her green bikini bottom. I used my left hand to reach all the way into her bikini and fully grabbed her left ass cheek. She groaned a bit into my mouth with that butt grab and the encouragement continued by Nikki. To save the embarrassment of Nikki feeling me get hard I turned her onto her back and now I used my right hand to support myself over her looking into her eyes. We both looked at each other and I said to her, “Nikki is this wrong is it wrong that I want you so bad right now” and her response was to grab the back of my head and pull me into her waiting lips and we continued to kiss.

I was so turned on by my step sister and in my mind I was reasoning that we were not blood. I also used the be nice to each other for the summer deal. I started to kiss her neck and nibbled softly as well alternatating both actions. I then moved up to her ear and whispered into her ear that I want to make love to my sister Nikki. Your making me so hard Nikki and I cannot stop now cause I want you and all of you. I went right back to her neck and now moved lower down and started to kiss her bare skin above her bikini top. I heard Nikki’s voice say the inviting words, “please fuck your sister hard please I want you to fuck me hard!!!!!” Those words stopped me instantly and I took that as an invite to have my way with my sister.

I sat Nikki up and I was in front of her and reached around her and untied her bikini top and took it off of her and throw it on the floor. There she sat that sister I hated on and referred to her as BITCH top less and only one more skimpy piece of clothing is keeping me from making love to her. She had perky little tits with small nipples that were erect at this point. I put both hands on her tits and looking down at her I started to massage her tits and told her how much I love her tits. I began to pinch her one erect nipple which made her shudder with pleasure and I smirked over her reaction and promised her she is going to be pleasure all day long. I bent forward to take in as much as I could of her right tit in my mouth. I ran my tongue on her nipple and was enjoying feeling her erect nipple. She was still siting up as I continued to alternate between giving attention to her left and then right tit. I always gave special attention to those erect nipples and I could continue hearing her moans of pleasure which kept encouraging me to go further in to exploring Nikki’s hot body. I started to kiss below her perky tits and down her flat tummy and then ran my tongue into her belly button. I was so wanting and needing to go all about three or four more inches to explore my sisters forbidden womanhood, but I stayed right there playing with her belly button.

I slide off the bed and looked at Nikki on the bed. All that was covering my bitchy step sister was that skimpy bikini bottom and she looked hot. I wanted to not forget she could be a bitch and thought to myself let’s expand this meeting. I ordered Nikki to get on all fours on the bed and bring your dirty nasty self to the edge of the bed. Eyes wide open she took in what I said and demanded and she moved quickly to follow my orders. Now she is on all fours looking up at her brother. I was standing in front of her with a raging hard on pressing against my basketball shorts and I reached down and grabbed the back of her head. I pulled her face into my hardon and blamed Nikki for making me so hard. I continued to rub her face all over my rock hard cock still in my shorts. Even with me forcing her into my hard cock I catch her still trying to open her mouth so maybe she could get a mouthful of my hard cock. I say, “Nikki I see you trying to open your mouth to get a taste of my cock you dirty little girl!!!!!”. I bet mommy and daddy would be so mad if they knew you were a dirty little girl and now turn yourself around for me and still stay on all fours.

Now I had my stepsister’s nice round firm ass right in my reach and I took a few minutes to just stare at her tight ass. I took my right hand and quick slapped her left barely covered ass cheek. She giggled and somewhat shook her ass from the reaction. Then I took both hands and rested them on each cheek and began to massage them softly which made her bikini bottom move up into her ass crack acting as a wedgie. I was moaning in pleasure as I continued this massaging and seeing her ass being more exposed to her brother. I told her that if her bikini bottom is starting to bother her as it continued to ride up her ass just instruct me to take them off for you. Nikki turned her head around towards me and we locked eyes as she said, “please please take my bottoms off please i want you to!!!!!” I reached up to the top of her bikini bottom and slowly rolled them down her ass and brought them right to her knees and left them there as she was still on all fours. Slap… then two slaps to her left cheek… Slap slap slap to her right cheek… I put my hand on her right cheek then I pulled my hand back further then before and SLAP to her ass again and all the strength of that slap had her ass cheek shaking somewhat and a slight red handprint. What made me so hot was that Nikki was still moaning with pleasure as she was enjoying this I think as much as I enjoyed it. I then moved down to start to lightly kiss those bare ass cheeks of hers and would every once in awhile run my tongue towards her ass crack. I finally went mouth right against her ass crack and used my hands to open up her cheeks which allowed me to run my tongue up and down her crack. I finally got to her rosebud and put my tongue right against it and just ran a few circular motions around it as she responded with louder moans of pleasure and words of her inviting me to go further.

I all of a sudden stopped and went to the other side of the bed. We were face to face and I couldn’t pass another chance to kiss my step sister passionately. I then said, “Oh FUK Nikki your mom will be home in less then fifteen minutes so you gotta go get dressed and stopping acting like a little slut”. I reached down and got her bikini bottom and put it under my pillow and told her I want this so I can jerk off too it tonight since we didn’t get to finish now go and get some fuking clothes on and I slapped her right ass cheek hard.
