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 facesitting 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 time!
