愛玩隷嬢 ～Doll～

You lose your way and get to a big house in the backwoods where a girl and three maids are living. You start to work as a servant there. What you imagine is an erotic life with those girls but a butler orders you that your job is to be a servant for those girls and to train them. Actually, this house was built to train girls and make them "dolls" to serve for rich people.
