Hanging from your finger tips show

My friend since I was 7 is always showing off about sex. He has jacked off in town, fucked women, next to the town fountain, just for a few. Now he has taken up the art of showing and imbarsing a guy, or guys. Last weekend we were sitting there and he said then and he bet us that he could do 20 stomach curls while hanging from your finger tips from a door frame nakid faster than anyone could. So two of the guys said$20 bucks and they stripped and jumped up and grabbed the door frame with their finger tips when the first guy started he drops to the floor after 4 curls and we all have him shit he said here's your$20 and he got dressed and laughed and sat down. Then the next guy jumps up and when he hit 5 curls he came all over the room. Then he drops down.i asked him what happened? He said that was the most intense cum load he has ever shoot off. Then the next guy jumps up and everyone who tried it came hard at around 3-5 curls. And if you do it fast you can cum in 3, but at 2 your nuts say I'm coming hard. If you don't believe this try it.
