Mary does compensated dating but adamantly refuses to have sex. One day as she meets a client as usual, the client turns out to be a big breasted lady named Sayoko. After initial surprise, she goes on more and more dates with the woman that gives her plenty of money just for hanging out with her.

She goes shopping with her and to all sorts of fun places like karaoke, game arcades and net cafes when she decides to invite her somewhere a bit more out there: A girls’ night at the love hotel.
