I have the slave, in a special bondage bag, made from strong canvas and with leather straps all around his body ...also his hands are locked in sleeves inside the bag, so, he is really helpless under My ass! I give him a gag made from My panties I wear it all day and I have fun smothering him with My ass clad in leather! Soon he get erected, so I can feel his erected cock trough the material of the bag so I,,make love,, with him ...haha ..then, I decide to ruin his orgasm ...you will see I see a huge amount of sperm... Of Course, his cock get locked back, for a very long period!
