When I was 13 my older sister caught me in the laundry room sucking her boy friends dick. He had tried many times to talk me in to doing it but I never would until that day and while she was in the shower he and I went in the laundry room closed the door he pulled his pants down took out his big dick and I was on my knees doing what ever he told me to do and he forced my mouth down over his dick and made me take his cum in my mouth and I was still on my knees trying to wipe his cum off my mouth and his dick was still out dripping with my spit and his cum when my sister opened the door and started screaming at both of us. She ran him off and I went to my room and closed my door and couldn`t stop thinking about it and jacked off like crazy.
They made up in about 3 weeks and he was back at the house like before but my sister made sure we never had a chance to be alone. weeks later Our Parents went on a short weekend trip and my sister and I were staying at the house and her boyfriend came over and stayed late. They both came in my room and my sister told me she really wanted me to do something for her and told me her boyfriend wanted you to suck him off again. I didn`t want to but she has her ways of getting her way and he kept after me to do kit again too so I ended up on my knees sucking his big cock with my sister sitting on my bed watching and he forced my mouth down on his cock again and shot his load in my mouth and she watched me gag on his cum and see it drip out of my mouth then they both left my room. Late that night they were back to make me do it again.
Weeks went by and they were taking me with then every here they went and we would park out by the lake and he would get in the back seat and take out his cock and my sister would get off watching me suck it and take his cum in my mouth. She enjoyed it as much as he did and once or twice a week if not more I had to suck his dick while my sister watched. She started letting him take me with him when she couldn`t go so he could get his dick sucked and she wouldn`t have to.
One day out at the Lake in the back seat of his car I was sucking his dick like always and he told me my sister wouldn`t fuck him so he decided that he was going to fuck me and had me get naked in the backseat of his car and I cried the whole time he forced his big dick up my asshole then let him lay on top of me and sweat all over me while he was fucking me and I was crying then he came in my ass then just laid on top of me humping me telling me that I would get used to it and that he was going to fuck me some more because my ass was so hot and tight. He was a big guy hairy muscular and very heavy and he fucked me very hard and told me to take it like a girl then told me my pussy was so good then he told me to tell him I wanted him to fuck me and cum in my asshole. He made me say it over and over until he came up my ass then when his dick came out of my ass cum ran out of me like a river then he told me to clean his dick then handed me a rag.
He fucked me once or twice a week and I thought my sister didn`t know about it but come to find out she told me she knew all about it when she was in my room on day. She told me I was a nasty little bastard and the next time Mom and Dad went out of town she was going to watch her boyfriend fuck me in the ass then told me as long as he fucks you I don`t need to. Two weeks later we were home alone for the weekend and he came over they made me take all my clothes off and once he got his dick in me my sister started to undress and she fingered her pussy right in front of me and told me to lick her fingers and watched her boyfriend fuck me and cum in my asshole two times.
I thought they were finished with me but he held me down on the bed and my sister sat on my face and told me to eat her pussy and make her cum and after she came she peed on my face then laughed and told me to clean it up. This went on for a long time and they did a lot of nasty thing to me and made me lick his and her ass give both of them oral sex and he fucked me a lot in front of her and she would be at home alone with me and take my pants down and make me stick things up my ass in front of her and she liked to tie me to the bed on my back and sit on my face and make me eat her pussy and lick her asshole. One day I caught her sound asleep while we were home alone and tied her to the bed then when she woke up I let her kick and scream as loud as she could while I shoved things in her pussy then used the handle of her hair brush up her asshole then let our dog in put him on the bed and let him lick her pussy for about an hour with the brush handle still up her asshole then left her tied up and she had to piss all over her self then I turned her over and spanked her ass hard turning it red and fucked her ass with the hair brush handle then left her tied up all night long to go in her room and treat her like shit when ever I wanted to. I shoved a cucumber up her ass and jacked off on her and made her promise to keep her nasty ass boyfriend away from me or I would tell on her for what they did to me then when she promised I stood over her and pissed all over her then left her tied up with the cucumber up her ass a few hours while I pinched her nipples slapped her tits and jacked off on her a few more times then just for kicks I took the cucumber out of her ass and fucked her up the ass and came in her then went back in her room and fucked her ass a few more times then I fucked her sloppy c**t and came in it too.
When I did untie her she ran in the bathroom locked the door and to this day she still has a huge fear of me but I got my revenge and she knows it.
