After the first installment featured Mayo and her water-soluble swimsuit, the sequel focuses on her friend Yukie in another outdoor exposure setup. Yukie is shy when her breasts are touched, but her moans soon reveal how much she enjoys it. Asked to give a blowjob, she has to move to another spot with her ass still exposed when someone approaches. She resumes sucking, moves to a hotel, and cheerfully licks his balls as well. Once penetration begins, she becomes fully aroused and lets loose, ending up delighted after being creampied and politely thanking everyone at the end.
