Miu takes her gal wife Natsuki out for a day trip. Meeting up in the city and riding the train together, their chemistry is already intense. Once they arrive at their destination and enter their hotel room, the erotic atmosphere grows thicker. Even while soaking in the hot spring, their passion doesn't stop—scenes escalate quickly with squirting, anal masturbation, and increasingly daring acts. In the open, liberated setting, their hot spring play becomes more intense, evolving into reverse lesbian play, deep kissing, and bold acts like pissing and drinking piss. The deepening passion between the two is absolutely irresistible.
