In a dimly lit room, a bondage contraption holds Shinobu Kocho in place, his thick cock straining against the restraints. Mitsuri Kanroji, his guide in this depraved lesson, teases him with a wicked grin as she attaches a milking machine to his engorged member. The machine hums to life, sucking and stroking his cock with relentless intensity. Shinobu's body tenses, his breath ragged, as he fights the urge to come, his voice echoing with cries of pleasure and pain, a symphony of taboo lust.
