oh yea ........ couple of times
once while getting fucked in the ass by a rather large and curved cock that hit my prostate just right, my legs were on his shoulders as he was building a nice rhythm and I remember trying to not cum and suddenly my cock just started shooting all over my chest, neck and face as my arms were stretched out on the bed trying to hold back ......lol, oh well
other time was one of the first times I had my butt licked, this guy was so hot and had me so worked up I wanted to start pulling my pecker while he ate my ass and he held down my wrists as he really went at my asshole ....... all I remember was wrapping my legs around his head so tightly and then I had cum all over my face .... again, lol
the kind of thing that is hard to replicate, the circumstances, hotness of the guy, and horniness of me, but wow, nothing like it
