unexpected experience

I am a young (26) year old gay college student. Recently I answered a ad requesting a young male willing / able to do some light bondage. he was out in the country, very remote. I arrived & immediately was ordered to remove all my clothes outside. I was sat in a chair that was open where my cock & balls protruded underneith. Legs spread wide apartArms strapped to my sides & my head was in a make shift thing. I was unable to move it sideways or backwaed or forward. At first only one guy was there. But, soon several others appeared. They all began feeling me up all over & poking & probing me all over, including my butt hole. They attached clamps to my nipples. All the while taking turns fucking my mouth, gagging & choking me, as I was unable to back away because of the head thing. They kept reaching beneath, squeezing & pulling my cock & balls. I dont know how, but I did manage to get a erection. Suddenly, without any warning they inserted sometjimh deep into my pee hole & at the same time something deep into my butt hole. My nipples are extremely sensitive. I believe that was the most painful thing. I dont know how many cocks fucked my mouth, but, cum was dripping down my chin & all over my chest. After more than a hour, they took a break for a while. But, later continued to do a repeat. It was evening & getting dark. They released me, but, put me in a cage overnight. The next day, I was again in the previous position. After a while a few more guys showed up. It started all over again. Most of that day. Again, I spent the second night locked in a cage. The third day was a repeat of the 2 previous days. I was finally released & driven to town. I never learned who they were or where it all took place.
