Taking advantage of the weakness of the poster girl who helps out at her family's public bathhouse, the girls are eaten by lesbians one after another! They invite their friends to the bathhouse, and the perverted lesbian who "likes younger men" hits them with female pleasure one after another! They betray their best friends and are forced to join in...there is no escaping the lesbian swamp! Although they are confused by the repeated lewd acts in the women's bath, the girls one after another fall completely to the experienced techniques of the older sister!
