I hid a camera to record I fucking his cock

My husband told me yesterday that just rubbing his cock against my pussy could make him cum really fast... and it was just like that. I hid a camera to record it all, I put it where he can't see it but I can see my ass rubbing her cock. Al the end, the amount of semen that came out of his cock was amazing. He was very angry about this and bet me that for the next fucking I would finish before him.
