It started over two years ago and I must admit that I am abused. I'm often violated, treated shamefully, and as much as they have put me through, I am at times totally humiliated. I knew Karen was a tough girl but nevertheless got involved with her. Shes 40 and I'm 31 but sex in the beginneg was good even though she was always the dominate one. She lives with Ellen and for a long time I suspected she was bisexual but know now she isn't. About two years ago I started to realize how kinky she was mainly because she began wanting to shave off my pubic hair all the time. I allowed her to do it and as months went by one night she let Ellen watch her do it and also maturbate me. I didn't know Ellen was at the door watching until after I had cum. It was embarrasing but I started to consider how arousing it was also. When Karen asked if it offended me I uttered, I don't think so. That night opened another world to me with kinky sex and lack of respect for me. I tolarate it now for my own gratification but suffer also to satisfy Karen and Ellen. The good part of it is that both of them masturbate and give me oral sex. I never have intercouse with Ellen but do perform oral sex on her often. I came to realize they enjoy tormenting me by not just humiliating me but started what could be conscrewed as torture. It began when they started tying me up at first only shaving my body hair and never listening to any complaints I had or objected to. Ellen was the first to insert a dildo in my rectum and gradually things got more intense. I still have sex with Karen alone a few times a week but since it all started at least once and often twice a week I am treated as a submissive, which I truly have become. After only about six month into this, Karen and Ellen have been taking me down to their basement and tying me to a large oak table. They also have what appears to be a saw horse only it has carpet tacked over the top and legs. When they tie me to that I'm draped over it with my arms and legs tied down and I am always naked. Without asking me if I had any objection, they not only began spanking me but also adorned a stap on dildo. Once I was securely tied down they took turns as one would play with my genitals as the other began fucking me in the ass. They just continued no matter what I said and once the pain of it subsided they would give me oral sex and often let me cum in their mouth. They just told me they like taking advantage of me and the fact is I am always satisfied when they are done with me. They do make me give them oral sex all the time and often sit on my face when I am tied to the table. Sometimes when on the table they tie my legs bent up and open and both either suck my dick or masturbate me when they insert a vibrator into my rectum. As bad as it may sound I do like the vibrator but still don't like it when they screw me with the strap on dildo. One night almost 11 months ago they had me tied over the saw horse. Ellen was wearing the strap on and began penitrating me as Karen was playing with my penis and scrotum. She did put ky or vasaline on it but it did hurt at first. Then I heard Karen say "come on down" and as I glanced towards the step saw two pairs of shoes and ankles only. I knew they were girls but had no idea who they were. All I knew was that they were behind me watching Ellen fuck me with the strap on. I couldn't believe Karen would let this happen and was so ashamed and humilited I started to shake but couldn't move. Ellen was more aggressive with the strap on and was penitrating me so deep I began begging her to stop and all I could hear is them laughing and joking around. My penis even went a little limp but then Karen began masturbating me until I finally did cum. The two girls were in front of me but I still couldn't see who they were and could only see up to about their waiste line. Ellen pulled the dildo out of me after I ejaculated and they let me stay that way and took turns spanking me, again in front of the two other girls. I was laying over the saw hourse for almost an hour by that time and was getting dizzy from it. I must have sounded like a idiot and kept asking them to untie me. Before they did the two strange girls went back up the stairs and left. I felt disgraced and was embarrased. I told Karen I wouldn't let them do this anymore. I showered as I usually do and when I came back down stairs I just told Karen and Ellen they should have asked me first if I wanted those girls to see me like that. I asked who they were and Ellen only told me she works with them at the bakery but never mentioned names. They both apoligized but said they thought I would like those girls to see me naked and assured me I didn't know them. Over the next week Karen kept calling me, asking if I was mad at her and Ellen. I said I was but began to realize deep down it was arousing to me that those girls saw me so exposed. The next time I spoke to Karen she got me to admit it but I did tell her that Ellen put the strap on diddo in me to deep and it hurt badly. I had sex with Karen at my apartment on Tuesday and she told me to go to her house Friday night. Ellen promised not to push the dildo all the way in me and I once again let them tie me down. They had my legs bent and tied and wide open. First they shaved me and after Ellen dried me off Karen started putting a blind fold over my eyes and said the girls are up stairs. I think because I couldn't see a thing, I was more at ease but became nervous and humilited as soon as I heard them coming down the steps. This time they all talked and the first thing Karen did was to play with my testicals and penis until I got hard. Then I think it was Ellen who turned the vibrator on but at first only touched my balls and penis with it for a long time. I could feel her put the vasaline on my anus and she began inserting it in me. I'm not sure who was doing what but the stimulation was so great I no longer felt embarrassed or felt like they were degrading me. I actually wanted to see who these other girls were. Ellen refused to take the blindfold off of me. Karen kept asking me if I was going to cum and she would stop jerking me off for a short time but Ellen kept moving the vibrator in and out of me. Ellen let me cum after awhile and before they untied me the girls I don't know left. It excited me because I didn't know and still don't know if any of them touch me or spank me. I don't even know if Karen and Ellen ever let them penitrate me either with the dildo or vibrator. When I ask about it they never tell if these girls do anything to me. This has gone on since, two or three times a month. I keep asking who these girls are that come and watch me and perhaps participate, but Karen and Ellen won't tell me. Two weeks ago Ellen finally did tell me its not the same girls all the time and that there are nine that have watched what they do to me. I know when one or two of these other girls are coming over because Karen and Ellen never get undressed when they do and never give me oral sex either. They only shave me, masturbate me and use the dildo and vibrator on me. If they have me on the table I am always blindfolded when the other girls come down the basement. When they tie me over the saw horse I can see but can't bend my head up enough to see who they are. I can tell 3 of them are fat girls just by the size of their ankles. They do talk when here but I don't recognize any of their voices and Karen and Ellen have promised me they are girls I don't know. I have asked about their ages but all Karen and Ellen tell me is most in their 30's and 40's, two 20's and one 50's. When all that is going on I am no longer humiliated by it. The crazy thing is when I think about it at work or when alone, I am horrified and feel shame for submitting to it. I can't imagine what these women think of me and must asume I am a complete pervert. I know Karen knows a few of them but I think most of them work with Ellen. Its a large name brand baking company that has hundreds of employees. I know I am a submissive asshole but it gets me so aroused I keep letting them do it.
