Oshikake! Bakunyuu Gal Harem Seikatsu

A salaryman who was fired from his job and has no girlfriend is caught by some gals! He is treated like a molester just for looking at them, and the gals force their way into his house, demanding that he let them stay there, and have sex with him to kill time! This man, who has no experience with women, is toyed with by the gals who know no shyness! Whether in the living room, the bath, or in bed, the girls' "inspection" never stops!
