In'yoku kaika! Miwaku no love house

Miku (Yui Kawagoe), who is deep in sex, was a virgin without connecting her lover Otake and her body. There was always a undershirt woman beside Miku. In fact, the undershirt woman was Miku's aunt, the spirit behind her, and she who lived in the Edo period was a sexually greedy and free-spirited woman.
