I totally flatten my slaves balls in my peep toe pumps, I love the color his balls turn to while all my weight squash is nut sack... I was very hard on him spiking and standing full weight on his nuts... I really want to pop one... I switch to bare feet and crush his crotch more, smearing it all over the table, jumping on his balls until the cum splattered everywhere. just when he think im done I jump as hard as I can on his balls... I think I popped one..hehe
