Muscle Goddess Rapture fed her slave a dick pill, then stuck him in the cock box. Rapture gets his cock nice and hard, so it is stuck in the box, then proceeds to destroy it. Using her bare feet, Rapture tramples and crushes his cock with all her weight. His dick bends painfully as she applies full pressure. Rapture uses her heels and arch of her foot to smash her slave’s cock mercilessly.
She wants him to stay hard, so in between crushing his cock, Rapture gives him a HJ and FJ. She strokes his trapped cock until it starts leaking with pre-cum. Her slave is ready to cum, and begs for release, but Rapture has something else in mind. She tells her slave that she’s going to trample his cock with heels on, and that if he can take it, she’ll stroke him until he pops. Her hard shoe, on his hard cock, in that hard box, is more than he can take. He groans in pain, almost freaking out as Rapture slips and almost slashes his cock with her heel. Since he didn’t fulfill his part of the deal, there’ll be no cumming for him, and Rapture leaves him & his hard cock stuck in the box.
