Rapture is feeling especially muscular and heavy today. She breaks out her new restraints, and bounds her slave with his hands attached to his thighs. Rapture informs him that she's going to use hi as a trampoline. She starts with his stomach, trampling him with all 185 pounds of muscle, and jumping up and down on him. Rapture moves up to his chest, then his head, before repeating the process on his throat and cock. How his neck is able to withstand her muscular body jumping on it is beyond us, but endure it he must, until Rapture decides she is finished.
