The husband ties up his wife and films her. So obscene and beautiful. Both husband and wife are more excited than usual. The wife is confused by her husband's desire to film her tied up by a professional bondage artist, but she nods. Even after returning home, the excitement doesn't die down and the sex is an exceptional pleasure. After that, the wife, unable to calm down with her sexual desire, masturbates with self-bondage in the kitchen late at night. Then, without her husband's knowledge, she visits the bondage artist alone and asks him to tie her up and train her.
