That JAV

There was a mysterious woman named Nanako who always wore a black robe and had been in mourning for her ex-husband for a long time, and had been bereaved of him four times. She frequently changed her address and lured the next man in mourning, binding him with a hemp rope and making him do her sexual training as she wished. The man is so absorbed in Nanako's bewitching body that he enters into a marriage contract with her in order to completely dominate her... But this woman is a ferocious female spider who, when she has fully satisfied her masochistic nature, devours the approaching man with her poisonous fangs and devours his entire inheritance.
