years ago, in my 20's, before HIV, I picked up a gal one nite in a bar. we knew each other already. after the bar closed, we went back to a buddy's house to party some more. I gonna go the "cliff's notes" route. we got fucked up and were fucking on the couch then the floor. after we both came a couple times, I passed out. my buddy had gone to bed while this was going on. I was semi conscious and remember her going to the bathroom. I woke up with her sucking my cock til hard and riding the hell out of me, both cumming again. my other buddy came home during this, and after we were done, I was aware that she went into the bathroom & his room. later, she awoke me again, sucking my cock til hard, saying she needed my big cock again, my last buddy was not big(I knew that). I asked if she fucked all of us, she said yes. so she rode me again, we both came again. in the morning, she sucked me off, and I gave her a ride home. she commented that I was the best of the 3 of us guys, and the biggest. that was puzzling, the second guy she fucked is really hung, bigger than me. she begged me not to tell anybody what had gone on, and I agreed. my buddies were all asking me just who the hell she was, and I told them not to say a word.
she was not an ugly girl, a little plain, a little overweight. we saw each other from time to time, but never fucked again. I never said a word to anybody, and my buddies didn't either. she apparently did, as I later also fucked 2 of her good looking friends, as they had knowledge of my larger than normal size, and were looking to get laid.
I wouldn't do that today in this day and age.
