The series follows a seemingly straight-laced discipline committee member who gets caught with his porn stash by two beautiful, domineering gyaru classmates, Miu and Yui. Using this as blackmail material, they completely subjugate him, turning him into their personal semen-milking toy. The entire arc is dedicated to his systematic sexual degradation as the girls relentlessly drain his balls on a daily basis. They force him into non-stop sessions, using aggressive handjobs, deep-throating blowjobs until he gags, and smothering paizuri where he cums all over their massive tits. He becomes a mindless, quivering wreck whose only purpose is to provide endless loads for these insatiable bitches whenever and wherever they demand.
