Cock exposed under my feet

His cock and balls are exposed under my feet and totally in my power. His manhood is intimidating and I can do with him everything I wish. This time I decided not to use my hands at all, he is not worthy my soft hands today and I will use only my foot. It seems that his cock like my foot because in no time he is rock hard and swelled. To punish him I'm pressing his balls but it seems only to harden his erection. Anyway I'm stroking his cock and pressing his balls until he start cumming so I have to stop and ruin his orgasm.
