The tattooed beauty "Sui Mizumori" finally makes her lesbian debut. Her partner is her best friend in both private and public life, "Ranran". Arriving at a hot spring town far from the city, the two chat about their memories. Back at the inn, Ranran torments and humiliates Sui as if their friendship until now had been a lie. Driven to blushing ecstasy by insane tongue techniques. A holy water facial shower from her best friend. Lesbian training while bound from her out-of-control friend. Dripping with a double-headed dildo, her orgasmic piss flows into her partner's vagina. "Can we... still be friends... from now on?"
