After inheriting his late grandfather's sprawling mansion, Shougo Yoshisuzu's life takes a wildly erotic turn. He's immediately greeted by the stunning and utterly devoted maid, Youko Otosumi, whose sole purpose is to pleasure him in every way imaginable. Their nights are filled with intense, passionate encounters, as Youko introduces him to the depths of carnal ecstasy, her pliant body his to command. But their fuck-filled routine is quickly complicated by the arrival of more insatiable women vying for a piece of Shougo's cock. His childhood fiancée, Ayane, shows up, demanding he fulfill their promise with her tight, eager body. Hot on her heels are the frisky Mizuchi sisters, Mone and Mocha, a pair of mischievous nymphs who introduce Shougo to the exhilarating thrills of threesomes, their mouths and bodies working in perfect, slutty unison to drain him completely. The mansion itself holds a spectral secret: the ghost of a beautiful young woman named Reiko, whose ethereal touch sends waves of otherworldly pleasure through him during their spectral fucking sessions. Shougo finds himself at the center of a supernatural harem, his days and nights a non-stop orgy of sucking, fucking, and creampies as he navigates the sexual demands of a devoted maid, a possessive fiancée, twin succubi, and a lustful ghost, breeding them all in a relentless whirlwind of cum.
