This role-play is performed by adults. After their son grew up and left home, the couple had sex almost every day. This thriving couple who is having fun day and night, ``anytime, anywhere'' is upset... My son had to come home during the school holidays. As a parent, I'm happy. I can't stand my father Toru's excitement every day. My son doesn't move an inch from the living room. Then, Toru desperately wants to have sex with his beloved wife, Miki, so he takes her out to a very questionable ``love hotel.''
