Gyaru Harem Invasion.

An office worker who lost his job and doesn’t even have a girlfriend gets caught by a group of gyarus! Just for glancing at them, the poor guy gets labeled as a creep, and the girls forcibly barge into his house, demanding to live there. Out of boredom, they decide to have some fun with him! The middle-aged man, inexperienced with women, is relentlessly teased and played with by the shameless gyarus! Whether it’s in the living room, the bath, or even the futon, their “inspection” of him never stops!
