When you think of summer and the sea, you think of girls in swimsuits! Does the summer heat and the gaze of others make their pussies and libidos more open? Believing the rumor that a certain beach house on the Kamogawa River is a masturbation spot for perverted women, we installed multiple cameras in the "changing room," "shower room," and "toilet" for about 2 months... It's even more amazing than the rumors! I saw the raw desires of women! Among them, we have carefully selected and released 11 big-breasted girls! 160 minutes!
