Fitch exclusive Satomi Tsubaki's cute, plump, busty body is relentlessly digged into by her swimsuit! Satomi, who has begun to worry about her figure, recently signed up for a rumored diet class, and in a swimsuit that is even more embarrassing than the one she is wearing, the trainer gives her sexual harassment instructions and massages her, touching her all over without restraint, as she goes through a lewd sex diet menu... Satomi's body gradually becomes more sensitive and aggressive, and she ends up getting creampied in 3 scenes!
