Mecha Gishi Resta no Daibouken 1

The "Mechanics," craftsmen who develop and repair machines. One day in the city where Rista lives, a shocking event occurred: the robots went berserk. These rogue robots were hijacked by someone, turning them into HENTAI robots that attack the women of the city! "As the mechanic of this city, I'll solve this incident!" Rista bravely fights back, but she finds herself experiencing unknown pleasures at the hands of the HENTAI robot's tentacles. With slippery tentacles and... well, you know, Rista's innocent, voluptuous body is toyed with. Hang in there, Rista! Even if you face naughty situations, don’t give up, Rista!
