CBT under my rough sole dirty trainers! Seems as though footslave needed a little workout, so what better shoes to wear than my dirty trainers to stretch out those balls! Sure he may moan and groan but my motto is - no pain- no gain! LOL I give him the workout he deserves in that cock box under the tread of my trainers tugging at his skin all the while thinking that he need more weight for this to be a meaningful workout! By the end of the session my barefeet inside my shoes were getting so sweaty and slick I almost debated making him lick them clean .
