I woke up from my sleep in the middle of the night because of a bad dream. Running a hand over my forehead I was hot, the summers always suck when you have no A/C. I got up and made my way downstairs to the kitchen to get a glass or water and try to dry off from all the sweat. My younger sister was in the refrigerator and this was the first time I had ever felt somewhat attracted to her.

She was all bent over with her nice ass sticking in the air. She had on a long white tshirt and a pair of matching panties. I guess now would be a good time to explain what everyone looked like, in my family it was me I was 20 years old and I had two older sisters and a younger one. My names Jesse by the way, my younger sister was 17 and her names Kate. All of us have natural dark black hair and mostly olive skin, my sisters hard darker skin because they like to go tanning.

 The next older was Megan, shes 21 and my oldest sister was Rachel who is 25. Our mom is 46 years old and luckly our entire family was blessed with good looks. My sisters really had our mothers beauty and even being 46 she still looked great. Our mom had an amazing rack with that curvy hourglass figure and a large ass.  

Kate was just filling out with a bra size I think was a B and a little firm round ass, my older sister Megan had a pair of tits that were a D with an ass that was big enough to slap. Megan worked out a lot and she was beautiful and im not sure how other guys feel but she was muscular, probably in better shape than I was, shes a health nut and works out every day but she looked great. Then our oldest sister Rachel, she was a real woman, who weighed a little more than my other sisters Rachel had some DD breasts, and a very large ass with a little extra around the waist. She wasn't overweight but she wasn't skinny. She still looked hot.

So anyways im sitting here or actually standing behind my younger sister Kate staring at her ass and suddenly I snap out of it when I hear her voice "What are you looking at?" she asked turning around to face me and takes a sip from some orange juice. He hesitated "nothing I cant see shit, eyes still adjusting to the light I think im blind." I played it off and she smirked "Yeah ok..well im goin to bed night." she said then tip toed back up to her room and I just stood there and shook my head. I got some water and went to sleep thinking about Kates little sexy ass.

Next morning I woke up and went to work just like I normally do, spoke to a few of my co-workers and moaned and groaned about how work sucked, etc. I got home an hour early around 4pm and walked inside. Nobody was home. Odd usually Rachel or mom was home all day. I walked upstairs "Mom? Rachel?" I called out then walked over to my moms bedroom door and opened it up. She was passed out taking a nap on the bed. I just stare at her for a moment and suddenly noticed her in a new light.

Then it occurred to me, I was living with the most hottest women I've ever seen but I sighed walking back out of her room.

It was stupid and I know it would have never happened, they were family after all. I went to the kitchen and had some early dinner and watched some tv by now Kate and megan started to come home and by 7pm we were all doing stuff at the house. Me and my sisters were all watching tv together for about an hour until Megan and Rachel ended up taking off to hang with friends. Mom was doing dishes while Kate sat next to me.

I glanced over at her she was wearing a pair of black pajama pants and a white tank top all curled up against the pillow "Lets watch twilight!" she said all excited suddenly. I just blinked "fine whatever...the news was getting boreing." I said sitting there in a pair of red shorts with no shirt on. It was odd because I turn the movie on and Kate suddenly snuggles up against me resting her head on my lap. Wow this was new I thought to myself.

About halfway though the movie we started talking while watching "Hes so pretty.." kate said and I just smirked "I could play a better vampire than he could, plus his whole stalker thing is creepy.." kate giggled "yeah you're cute enough thats for sure.." I glanced down at her "bullshit if I was cute id have a girlfriend.." I said softly. This made kate hug me tighter "hey if we weren't related I would so be your girlfriend..." I felt a rush of heat flow though my body as ideas and images ran in my head picturing me and kate going at it in my bed but they were quickly washed out. I smirked "so lets say we were going out what would you do?" I asked slightly feeling playful and curious at the same time. Kate looked up at me and gave me this evil grin. Suddenly she turns to face me and straddles me. I dont know if she ment to do this but I could feel her tight pussy rubbing against my now hardening cock. She could totally feel it between the thin fabric of our clothes and I just tried to pretend it wasnt there "I would hop on you like this..." she said softly  then leaned in and kissed my neck. Holy shit was she doing this for real? I thought and just played along for now, finding my hands to rest on her hips "W-What else?" I managed to spill out. I could feel her lips trail up my neck and suddenly she kissed me. Her hips even started to rock slowly against my hard cock.

After that I pretty much entered fuck it mode, all reason was out the window now and I kissed her back parting my lips so our tongues could meet, which they did and I pulled her close, she moaned  her cold hands resting on my shoulders then she broke the kiss and got up "Lets go upstairs..." she said playfully then ran up before I could even stand. I looked down and saw a wet spot on my pants where my cock was...holy shit she was wet. I got up and hauled ass upstairs to follow...
