Mechanics, the skilled craftspeople who develop and repair machinery. In the town where Lista lived, a day came when robots went haywire. The rampaging robots were hijacked by someone, turning them into HENTAI robots that attacked the women of the town!

"As a mechanic of this town, I'll solve this case!"

Lista bravely fights, but experiences unknown pleasure from the HENTAI robot's tentacles.

Lista's innocent, curvy body is toyed with by the slimy tentacles.

Go, Lista! Don't give up, Lista, even though you're facing a naughty fate!

The robots developed by "mechanics" were hijacked and transformed into "erotic" HENTAI robots!?

Even this "eccentric" girl is melting and wet with the "fantastic" sexual techniques of the HENTAI robot!?
