Storyline
Futa warning. And that's not the half of it. Lovely Miku and her neighbor Yukito are victims of his onee-chan's new invention: copipe gel!

Yukito gets a "copy" of Miku's ample breasts and Miku gets--er, well, you get the picture. Erotic chaos ensues as everybody--including Marie onee-chan--takes advantage of this bizzare situation. (And then add love to the mix...)
