The series follows Kouta as he visits his busty cousins, Haruna and Yui, at their family's dairy farm. He quickly discovers their perverted secret: they need a man to breed with them and suckle their massive, milk-filled tits to stimulate production. Kouta is put to work as their personal bull, his mouth and cock used relentlessly to drain their engorged udders. Each episode escalates the depravity, featuring intense, hardcore scenes of incestuous group sex, forceful lactation, deep-throating, and creampies. Watch as Kouta is fucked senseless and drinks cum-laced milk directly from his cousins' swollen nipples, getting completely lost in a non-stop orgy of breeding and milking.
