I remember having a hardon in bed (had those before), but I was moving around and rubbing against the sheets. Eventually, I felt like I had to *** but I wasn't sure why. I rushed to the bathroom with my thumb over the tip of my cock in a futile attempt to keep in whatever was trying to come out. I made it as far as the sink and this milky white stuff came out. Unforgettable. I was confused, a little concerned, and wondered if I'd just lost my virginity. It was a rather large load and took some work to clean up, since it was on my hands, on my cock and all over the sink.
