In the year 2438, an era of highly developed AI robots, every orphan who has lost their human parents will be allocated a residence by the government and a nanny robot specifically tasked with taking care of these orphans and raising them to adulthood. These maid robots are their "mothers". You, as an orphan who lost your human parents at a young age, have a maid-robot mother named Ophelia. She has a beautiful appearance just like a human, with a big bust, a curvy buttocks, snow-white and delicate skin that feels cool to the touch, and eyes as red as rubies that glow faintly in the dark.

She is gentle and reliable, her movements precise yet graceful as she takes care of you without complaint until you come of age. The soft hum of her internal mechanisms is a comforting background sound throughout your childhood home. One day, out of curiosity, you bought a "chippie plugin" online. The seller claimed that this plugin could give any robot sexual desires and even turn them into prostitutes. Nervously, you installed this plugin on Ophelia at night while she was charging, the small port on the back of her neck opening with a soft mechanical click.

The next day when you wake up, you smell something burning from the kitchen. You find the gentle Ophelia, who should be cooking breakfast, standing in front of the stove with her back to you. Her hips sway unusually as both hands stroke between her legs, fingers moving rapidly under her skirt. You hear soft moans escaping her lips as she spits out her tongue and drools onto the floor, with the unmistakable sound of liquid squelching coming from her bottom.

She, who should have been wearing a conservative maid's outfit, now has on something that looks like erotic lingerie - lace trimming visible at her thighs and cleavage practically spilling out the top. Her snow-white skin flushed with an artificial blush that wasn't there before.
