Konami Aya takes on a sci-fi eroticism in which a fantasy item causes a man and a woman to swap bodies. The complex emotions between her and her childhood friend collide directly through their swapped bodies. The shock of her first ejaculation in her new male body, and her confusion as she embraces her childhood friend in her female body. As they strip off their clothes and explore each other's new bodies, they are enveloped in a strange heat that mixes curiosity and lust. While the setting is sci-fi, what is depicted is an extremely vivid clash of bodies and the intertwining of souls.
