Well some weeks ago I had sex with my Cousin sister, she is very good lucking and is one of those girls who hardly ever go out, Her mother is Latin and her father is British she has bright blue eyes and light brown/black hair, she has a normal height of a women and is slim with a big chubby ass and big tits. This is how it all started: My little sister had went to her house to play with her niece, nobody was home except the kids and my cousin sister. So i went to collect my sister from her house alone, we as cousins dont talk much e.g. my family and her family hardly talk. Im 20 and shes about 24-26 So i knocked on the door, my cousin sister opened the door I gave her a cheeky smile and she smiled back at me, she told me where the kids were so I went there and my cousin sister went off somewhere. I told my little sister to get her things ready, I needed a toilet so I ran upstairs and i didn't know which was the bathroom, I was just taking guesses going through rooms (she lives in a enormous house), so by chance I ended up going into her room, I said "sorry I was just looking for the bathroom", she says "i have a bathroom in my room its just over there". So I went into her bathroom and as i finished and opened the door she was on her phone texting a friend or something, I said "thanks", as I was walking out she called me back and says "have you ever had sex before" I said "no" and I was laughin as well, she says "do you want to have sex", I said "Yeah, if I had a chance", she then says "would you have sex with me if you had a chance" I started to smile a bit, then I thought to myself NO WAY, WERE COUSINS, So i turned serious and said No, were cousins. I had a absolute ROCK HARD, HARD ON, I tried to hide it by putting my hands in my pocket, she started to wink at me and looked where i was putting my hands, she says " you got something to show me", I was like DAMN. She then got off the office chair and walked up to me, I was slowly walking backwards, she came towards me hugged me and grabbed my penis, I jumped up a bit she slowly while hugging me pushed me onto the bed, I grabbed her ass and she was like an animal, she started to rub her pussy on my penis, she was looking at me and giving me the horny look girls give, i tried to talk but she gently started to bite my lips. She slowly slithered down where my penis was and took my jeans belt off and then took my jeans off, I started to take my polo shirt off, she got off me and went up to the window and closed the window and curtains. I got off the bed and helped her to take her vest off and her jeans. I was licking around her chest and neck and she was taking her bra off and underwear, I then moved down slowly and just started to rub my face around her boobs, she then pushed me on to the bed she was on top of me, I grabbed her and we switched sides so I was on top I started to snog her and she grabbed my penis started to rub slowly and she then placed it into her pussy, she was literally all wet down there. When i entered her it was the best feeling of my entire life, it was soo warm and just felt soo good. I then started to go in and out she was moaning very loud, i put my hand around her mouth so the moaning got a bit less loud otherwise the kids downstairs proberly would of heard. She was hugging me very tightly and I was just loving it, the warmth in her vagina and the warmth of her body made me want to stay there forvever. I started to go fast and she was just moaning loudly and i removed my hand from her mouth as her moans was turning me even more on, after about 5-8mins I was going to cum and i stopped, i didnt cum as i stopped just before i was the feeling came up. I tried getting up but she was hugging me tightly, so i just stayed on top of her for a while. I layed my head on her boobs and i closed my eyes, she says "want to go again", I said "no,no i need to go my sister is waiting", she says "no shes not, shes proberly forgot your even here, shes occupied its okay", I said "okay, then but it's your turn now", so I got up and i layed down so shes on top of me. She was rubbing my penis and i was snogging her at the same time, so as i got onto a hard on again, she sat on my penis and was bouncing on it, she then leaned over I gave her a kiss on the cheek, as she was bouncing, it was making such a loud noise as my skin and her skin was hitting each other like a clapping noise, I put my hands around her waist and she was going, she was going wild. As soon the cum feeling had come again, i told her to stop and she stopped and got off, I then said " want to to again last time, its my turn" as i gave her a cheeky smile, "she said okay lets make this a long one", So as i went on top of her she this time opened her legs wide opened and her feet were all the up near my face, (she did have good looking feet though) i put my penis into her and she started to rub her pussy, I was going for full throttle this time, she was screaming and shouting "FASTER, FASTER DONT YOU DARE FUCKING STOP", I was like wow okay, I was going fast as i could i was breathing heavily and kept and kept on going and still coulden't feel the cum on its way, she was just totally off it, screaming and shouting "FAST FAST FAST" she could barely even talk as she was enjoying it. I kept it going and going for about 15mins just enjoying it not trying to cum, the bed was rattling like mad, i said to her "im going cum a lot this time", she was just moaning and rubbing her boobs and grabbing her hair, as the cum feeling came around She was having an orgasm, she was shouting in a scary way, "GO GO GO GO, DONT STOP OMG PLEASE DONT STOP" I was there moaning a bit as soon as the cum came, i could feel it coming through my penis like a over flowing river, as soon as it was released I moaned very loud and she moaned too like every time a load was going into her she jumped abit and was "Ahh, ahh". I stopped cumin, and i layed on top of her catching my breath back, after about 2-3mins i took my penis out and as i took it out slowly, a load of cum was coming out too, it started to drip on the bed sheets, i got up and picked up her underwear and wiped my penis with it as she wasen't looking, i threw her underwear on the floor and went to the bathroom gave my penis a quick wash and walked out when I walked out of the bathroom and i was putting my clothes back on and when i reach down to grab my trainers she came upto me naked and hugged me tightly, we were hugging, kissing and talking to each other for 5min and she says how she was shocked on how powerful the cum was going into her, her hair was still smelling beautiful after all that work, I was staring at her admiring her blue eyes saying how beautiful she looks, she gave me a love bite on my neck where it can be covered up. As i walked out she grinned at me and says, "we can do it again sometime" with a wink at the end. She stayed in her room, I walked out and told my sister lets go and we walked out, as i sat in my car, I did a quick glance at her room and she was there looking at me and smiling away. Most girls would like me because of my car, as ive got a well paid job and a top BMW 535d 2012. But i knew she didn't like me because of my car or job. But after that I have not spoken to her or seen her, it's been about 3-4 weeks and i think shes pregnant with my child. I dont have her phone number or anything and I dont want to go to her house in case her family knows what happened and I dont want to face it. I don't think shes on pills or anything, I should have used a condom i dont think she had any, but at that time I had to cum in her i didn't want to disappoint her by stopping as she was going crazy. I am prepared to raise a baby, money and help isn't a problem in my family, but its just i did it with my cousin sister and my parents may go chaotic on me.
