In an industry-first, two pure and innocent AV actresses are taken to a real mixed-gender outdoor hot spring for a shocking experience. Both are adorable in their own way: one is the exhibitionist-type 'Iijima Kurara', who enjoys being watched by others, while the other is the shy 'Koamine Hinata', a 92cm G-cup beauty experiencing her first-ever exposure. The two encounter men at the mixed bath, leading to completely unscripted interactions with genuine amateur men. The highlight is the authentic, natural interactions unfolding in a realistic hot spring setting.
