VS-758 Hoshikawa Hikaru: Busty Temptation 14 – Cinematic

A doctor, tormented by a dark past and expelled from his medical duties, secretly imprisons a busty, beautiful female patient underground. He forces her to orally stimulate his ED-stricken abdomen, reviving his lost virility. Using tight bondage techniques and erotic torture, he employs her breasts and private areas to stimulate male patients' sensitive parts—this is the secret 'Stimulation Department,' a special clinic operating in the shadows of a certain hospital.
