The husband ties up his wife and films her. So obscene and beautiful. Both the wife and husband are more excited than usual. The wife is confused by her husband's desire to "film you tied up by a professional bondage artist," but she nods. He films his wife tied up in a beautiful yet lewd pose, teasing her with toys. The sex, which doesn't die down even after they get home, is an exceptional pleasure. After that, unable to calm down with her sexual desire, the wife masturbates with self-bondage in the kitchen late at night. She then visits the bondage artist alone, without her husband's knowledge, and asks him to train her in bondage.
