A GF and I decided it would be fun to do a live internet show for 10 or so willing observers. We got it all set up where we could hear what they said and they could hear and see us. Well it was an interesting situation that was for sure. I didn't really have stage fright, as I had no problem getting hard. However after 30 minutes or so the GF was getting a bit tired since we had really gone at each other for the camera but I was having a problem cumming for some reason. I really wanted to and my balls were rather swollen and ready as well but something upstairs was preventing it.
Why is this important? Well, at about that time one of the guy's shouted out a request for a position right while I was in mid stroke. Well the g/f went one way and I went another and on the incoming stroke I slammed myself into her in such a way that I crushed my left nut against her butt cheek.
The pain was increadible!! I went instantly soft and I let out a silent scream it hurt so bad. The g/f knew I had just hurt myself but didn't know why. She instantly decided to pretend that she was cumming because I was cumming and started shouting things like "that's it baby...cum in me", "dam your load is so hot", and crap like that (Yes, it was rather awsome of her to help me save face.) It was all I could do to hold myself up at that point as tears started running down my face. We eventually decoupled and she went and took care of the computer while I lay on the bed in a fetal position hoping like hell my ball had not exploded.
It was sore for over a week and I still shudder when I remember that shot of pain. Worst the boy's have ever felt bar none.
