That sounds just like the plot of a hentai manga I read, except it was sexbots.This story revolves around the life of Akira, a man who has been saving his money for over three years to finally obtain a computer. Unable to get the computer model he wants he is offered the same model from a shady man in an alley.
Oh.it is actually Model 2198, a super advanced gynoid who’s sole purpose is to serve and protect her “master.”
