A hot spring trip with Natsuki Rin, where the two of them just go wild with instinct and no script. After enjoying a train ride and sightseeing in the hot spring town, she goes to an inn and does some light exposure, a blowjob in the open-air bath, sex in the room, and toy play, all of which are full of private moments, revealing her true self that she doesn't usually show in front of the camera. Here you can see the raw and sensual figure of the life-size Rin Natsuki!
