extreme leather cbt inst. You think your pain loving cock can handle a leather extreme cbt? I cant wait to make you purple, blue, and beg for mercy. You will need rubber bands, a flat sole shoe ( preferably my flip flop) but boots or heels will do... A cup of ice, your hand and of course me. taunting your painful blows to your balls. The agony in your groin will be aching in agony yet begging for more as i leave you mangled and on your knees breathless from the extreme..
