“Break me more. Make me filthier.” Shizune Tachibana’s buried masochism is unleashed as her pride is destroyed in a locked cell and abandoned building. Bound hand and foot, she endures merciless deep-throat pistons, tubes pushed through her mouth and nose, and unknown liquids forced inside. Saliva, tears, vomit, urine, and semen are repeatedly recycled and swallowed until oxygen deprivation and orgasm merge, completing her transformation into an exclusively owned throat slave.
