I had just turned 18 and was caught by my 20 year old sister shoplifting some condoms. She video'd me with her phone and said that when the time came I would have to do whatever she said or she would show that video to our parents and the police. I didn't think too much of it but knew my day of reckoning would come. A couple of months later it came. She said we were going to her friend Tom's house and I would have to do what she said. I thought "Whatever. I guess I'll do what she said. How bad could it be?"

She drove me over to Tom's house and when we walked in he offered me a beer. I was only 18 but had drank beer before so I took it. She said I might need to be a little drunk to endure the night. After my third beer she said it was time to go to the basement. I thought "Sure, whatever." We walked downstairs to the basement and there was a guy sitting in the corner chair naked. I didn't think too much of it as I knew she was sexually active. Then they led me to the other side of the room. I saw two 4X4s about four feet apart with a bar between them. She led me to them and they proceeded to tie my hands apart on the 4X4s. I said "What the fuck is this?" She told me that this was my punishment for stealing. I figured one of them was going to spank me but she had other plans. She told tom that she would be back in an hour and he could do whatever he wanted. That scared me a bit. He walked around to the front of me and undid his zipper. He said I was going to suck his dick or I'd be sorry. I said "Fuck you. I ain't sucking nothing." He zipped up and walked out of sight. A few minutes later I felt my pants being undone and pulled down along with my underwear.

A minute later someone, either Tom or the other guy knelt down under me and undid my shirt. Then I felt something being clipped to my right nipple. Then my left nipple. There was something pulling them toward each other. It hurt like a bitch and I yelled. Then Tom said "Too fucking bad. You're mine now bitch." Then someone had their hands on my ass and was rubbing up and down my ass crack. I felt something being squirt on my asshole and then a cock being inserted. It hurt like a fucking bitch. About that time Tom walked in front of me totally naked. When the guy with his cock in my ass pushed forward I opened my mouth to yell and Tom stuck his cock in my mouth. I was being fucked from both ends. I wasn't gay and had never had a cock in my mouth but he just kept fucking my mouth. The cock in my ass hurt like a mother fucker and I noticed I was crying as he fucked me from behind and Tom was mouth fucking me.

About that time I heard my sister say "This is your punishment for being a little fucking thief. Now, you're gonna take everything they have to give you or the video goes public." Tom was fucking my mouth and the other guy was fucking my ass. Then I saw my sister with her phone stand in front of me videoing me sucking Tom's cock. I knew I was stuck. I couldn't do a fucking thing about it. Tom came in my mouth and the other guy came in my ass. When they were done the let me loose and sis drove me home.

That was bad enough, but then she informed me that I would lick, suck or fuck her any time she wanted. That summer there were plenty of times she was drinking and her boyfriend wouldn't fuck her. Those were the times she called me into service. That was almost 20 years ago. Since that time I have gotten used to sucking or fucking anybody she said. I guess she's sort of my pimp even though she's my sister. I fuck her occasionally but mostly she makes money off of me sucking or getting fucked by the men she knows. I don't mind too much and actually have fun doing it. We live together and make a pretty good living with me being her bitch.
