At a seaside beach house shower room, a hidden camera captures female guests washing their naked bodies. The footage shows them carefully cleaning sand from their skin, scrubbing their entire bodies with one hand on the showerhead. Some insert fingers into their vaginal slits to scoop out trapped sand. Hidden from the eyes of other guests, these women experience a private, intimate pleasure. The sound of shower water echoes in the private stalls, droplets falling, grains of sand washing away—revealing an erotic scene concealed within an ordinary moment.
