A husband who shoots his wife tied up. The extreme obscenity and beauty. Both the wife and husband were more excited than usual. The wife, while bewildered by her husband's desire to shoot her being tied up by a professional shibari master, still nods. The sex that didn't calm down even after returning home was a special pleasure. After that, the wife, whose sexual desire couldn't be contained, masturbates herself in the kitchen late at night. And then, without telling her husband, she visits a shibari master alone and asks him to tie her up and train her.
