Titre original : The Charm of M
Kenichi Sakaki lives with his wife Yoshino Ogawa, whom he cares for and has great sexual attraction for. One night, after a sexual act between the two, Kenichi receives a letter stating he has won a contest and is invited to get his prize on a specified address. After trying to approach the location by car, Kenichi and Yoshino get lost for a while but they soon find a mansion indicated to be their destiny by the GPS device included in the mysterious letter. When entering the house, the couple is welcomed by a maid who invites them to stay the night in one of the apartments. After a breakfast served to them in the following morning, Anna, the daughter of the mistress, introduces herself before making obscene comments about the couple's sexual life, shocking them and making Yoshino ask for staying alone. Afterwards, Anna leads Kenichi to another room and shows him a bound woman with milking breasts, questioning him if what he sees is interesting. Confused, Kenichi runs through the mansion in order to find his wife, just before receiving a telephone call from the house's mistress where she claims Kenichi has a wish to unleash his sexual fantasies involving violence, rape and sadomasochism. Then Kenichi gets into many BDSM situations with different female slaves across the mansion while trying to find Yoshino.
