a couple exchange swap hot spring trip the secret of defeating manneri !! my husbands are all right! the only ones you don't know?
Swapping hot spring trips prepared in advance so that each husband can have sex with his wife!! we don't know each other's wife... It is a trip that eliminates manner sex. Two couples sleep in a room. even though my husband is sleeping next door, i sneaked into his wife's futon... get out!
