I am a herring male but I am open minded and very very logical. I have in the past allowed men to have sex with me in all types of ways, I’m always on the receiving side. There came an incident when I was a senior in college and I put myself in a potentially life altering situation if police would be involved so I agreed to do something in exchange for a free pass in addition I got paid, it was to attend a gay orgy that was out of a porn movie. I had many things done to me that I actually enjoyed but the main part of the agreement I made was that at the end of the party I had to spread my ass and let a older man, older than my father with a huge penis fuck me for 20 minutes. The pain was incredible. The mans cut cock was 10” ( I was told) and thick. I never had a cock in my ass, probably an enema or suppository when I was a little kid. The attendees at the orgy did many times put things in my ass that probably stretched it to some degree but when this baseball of a cock pushed into my hole it wouldn’t go in. A load of lubricant was applied and after a hundred screams of pain the guy was determined to get his cock in my ass. I tried everything, relaxing , pushing back and pushing out like I was pooping, I wanted this to be over. When the pain was so excruciatingly hurting that I thought I’d pass out I felt his cock push into my hole. At first I could feel the chicks head in my ass and the pain diminished maybe 20% but then I felt the shaft go way up inside me and a different pain took over. The guy was successful in that his huge 10” cock was all the way up my ass, I could feel his balls hitting mine. He started to pull out and push back in again slowly, this also hurt but my mind was confused with all the types of pain I was experiencing. Problem was with this cock inside my ass I couldn’t move to easily if I wanted to leave. The cadence of the thrusts became faster and with each hard push into my ass each thrust hit my buttock hard and there was a slapping sound. I felt I was being split in two and soon his cock would come up my hole and through my mouth.finally I felt a type of vibration and a few super hard thrusts, after which came a feeling of a warm fluid filling me. The cock stayed inside me for what seemed like an hour but was finally pulled out. Once his cocks head was out of my hole an intense shot of pain went through my ass. His cum was dripping from my ass for an hour and if I reached around to touch my hole there was a severe burning sensation. I bled a bit during the night and had a sore hole for over a week. This is the biggest thing to ever go into my butt
