When Akane (Akari Mitani) gets wet, a penis suddenly grows and she turns into a man—what is going on?! Normally, she plays as a female, using her pussy, but the moment she touches water, she transforms into Akao (male version) and engages in bareback sex using his penis. Every time this transformation occurs, chaotic sex ensues with intense struggle, as male and female roles switch back and forth, creating the illusion that the story is taking an entirely new turn. This is a shocking transformative erotic work that opens up new possibilities. Fantasy sperm is used in parts.
