It is rather abnormally large, I do so admit. Almost to the point in which I was suggested to visit a doctor and see if there was anything wrong with me. Once I got to the doctor, he examined my penis, fondling with it, and eventually licking it. He proceeded to continue licking it and eventually began sucking on it. After about 3minutes of continuous sucking with the occasional brief gasp of air, he removed his mouth. He then proceeded to have a seat on my fully erected penis - Slowly moving his buttocks downwards with the little grunts of pain/progress.

After he had my penis fully inside of his (rather clean) rectum, he began slowly moving up and down. I began to feel a sensation, a rather pleasurable one at that. He slowly increased the speed of his movements, and that only increased the amount of pleasure. Eventually after about 10min of speeding at high-velocity on my erect penis, up and down, he and I simultaneously orgasm-ed. It was a very unexplainable feeling, but a nice one at that. After the muscle spasms, I became tired and fell asleep on the hospital bed. I woke up 9hrs later in pitch black with no one around. I barely found my way to the door and walked across the hallway to a window. I opened it, jumped out and walked home that night.
