I was soaking in an open-air bath. A group of five busty beauties arrived one after another... I panicked at the unexpected mixed bathing. The beauties, amused, started teasing me. They touched each other's breasts/tempted me lewdly!? They were also very interested in my penis! The beauties, beyond the limits of reason, had a massive orgy in the bath! Further, in the room, they enjoyed a feast of women's bodies and seaweed wine!
