Rio is a party companion at the only hot spring inn in a mountain town. "I love alcohol, but I get drunk easily..." She causes a lewd commotion in the inn with her erotic and cute character. "No more customers!" She is consumed by alcohol and pressure and gets fucked ferociously. Washing each other in the open-air bath, playing rock-paper-scissors and serving women on a plate, this is a paradise for men's dreams.
