Clothed cock cumming twice during handjob

I have used 3 cockrings on his balls and one cockring on the base of his cock to make him hard and ready for what will come next. I prepared a lot of elastic bands for hair and I'm using them on his cock. I put one after another starting from the base of his cock to his cock's head. He is extremely thick and sensitive and looks very funny, like warm clothes for his cock. It doesn't take long and he shoots his huge load in nicely ruined orgasm but it will be too easy. I have to continue playing with his hard cock and ruined again his another orgasm.
