After three long years of scrimping and saving, Akira races to the store when the 9821 model hits the shelves, only to watch it disappear in minutes.

What arrives instead is the advanced 2198 model, unfolding as Mimi, a sensual bio-mechanical girl whose presence sparks tender softcore moments in this uncensored vanilla hentai.
