What a nice thread!
I had a similar(ish) thing happen to me. It was the first time fingering the missus - first time fingering a girl ever, when we were, er, 18 I guess. We were in our friends bathroom, on the floor lol, her jeans and panties round her knees and I must have been doing something right because she got so hot and bothered, very wet and very loud moaning... that I blew my load in my boxers - I got so flustered and embarrassed that I didn't even finish her off!! ![](upload://kym5tZ5EfyJxs6TKHB1Q2HtGSpK.gif)
