So I have a twin sister who I am quite close to we talk all the time and don’t really care when we see each other naked, I’ve walked in on her fingering herself before and we both just laughed it was quite funny to be honest and she has seen me wanking in my room. This one time when we were 16 our parents decided that it would be safe for us to stay home alone together and to keep eachother safe while they went on a holiday together on the weekend for their wedding anniversary.So as we said our goodbyes we both knew it was gonna be a good weekend but not for the reason we first thought, our parents left us £150 pound for food and the next time we’d see them would be Monday evening.as they left I ran straight up stairs to play on my xbox as I knew this would be my only real chance to stay up late,

This is when things got a whole lot better for this weekend, while on Xbox I got up to go downstairs to get a drink as I was thirsty and my throat was so dry but to my excitement I see my sister on the sofa fingering her beautiful pussy,she was mostly shaved but left some hair on as she said it is beneficial during sex,boy did that give me the hardest boner I’ve ever had.So I walked in just telling her that I was getting a drink and asking her if she was okay.She caught me by suprise as she began to take her bra off as she was touching her hard nipples through the material, and she shaw my rock hard cock through the pair of shorts I was wearing and she started to rub it and as it got harder and harder,bigger and bigger she began to pull my shorts down and began to suck softly on the head of my penis it felt so good. As I was about to cum straight into my sisters mouth she teased me and asked what sort of kinks I had and after I explained to her that seeing her piss once got me totally hooked onto it she confessed that she felt the same and that she had watched a lot of naughty videos about that kind of thing.so we both got into the 69 position and she began to run her pussy all across my face moaning piss in my mouth daddy and as I began to piss she squirted all over me because I had licked into her g-spot to long for her to handle,I then turned her round and she put her self on top of my cock and began to ride me moaning my name in my ear, as I was about to cum she got off my cock and began to piss all over me and began sucking again the warm piss made me so horny that as soon as her tongue touched the head of my cock I came right into her mouth and it felt so good.

This isn’t the end of what happened as that was only Friday night, Saturday I decided was a fresh new day waking up in need of a nice warm bubble bath I had my breakfast while it filled and as I got in the door swung open and in comes my sister with her large breasts and beautiful pussy.she mounted me in the bath and we fucked nice and slowly until she began to piss while she rode me this turned me on so much I told her I was close to my climax and she quickly got off me wanking my cock off in between her tits she finished me off and let my cum drown her face. We carried on in the bath just relaxing and she let me finger pussy and as she came on my fingers I licked up every last bit of what was on them we let the bath water out and decided to take a shower to clean off she cleaned me and I cleaned her and just like that we carried on with our day.

Sunday the last full day,this is when the piss play got to a whole new level,she called me upstairs into her room and all she was wearing was a pink bikini and told me to take everything off but my boxers.so she sat on my cock in her bikini on her bed and it was odd as for five minutes we sat their no noise or anything except the tv on in the corner.as I was about to question what she was doing I felt a wet warm feeling all over my cock,she was peeing all over me and it felt so good,her warm piss drowned my cock and it got harder and harder,bigger than it ever seemed to be before,after this I rubbed her pussy through the panties so fast that she squirted all over my face and then she asked me to piss on her and she became my toilet slave as I pissed all over her she was attempting to catch it all in her mouth then she sat her warm wet pussy on my cock and chanced it letting me cum inside her it’s very lucky that we don’t have a baby on the way as I blew the fattest load I ever have inside her.it was Monday evening and our parents were back clueless about our great weekend we still make sure to do this from time to time as this was only the beginning of the year.everytime we are home alone I’ll be inside her and she will moan my name to the whole road.
