On an afternoon like any other, high-schooler Nanaki falls into a pond that's shrouded in legend and suddenly turns into a girl! Although mortified, he loves how soft and smooth women's bodies are, so... Why not have some fun? He tries on his own, but can't quite seem to get it right... And that's how Souma, Nanaki's step-brother, finds him when he gets home from work! Once Nanaki's hero, "Soumy" is now nothing but an annoyance... That is, until Souma shows Nanaki how to fully enjoy a woman's body! Why is he doing this, and why does it feel so good!?
