Artificial vaginal penetration is 200 times more pleasurable than a human vagina! Adjustable wetness, temperature, and tightness!! A specialized sex robot that becomes more obedient the more you ejaculate. Kuramoto Susumu HMN-775

I'm all alone. I work myself to the bone out of loneliness, and this sex-processing robot I bought with all my savings. I originally wanted the latest big-breasted, smiling robot, but due to the seller's mistake, I received a flat-chested robot that never smiles. I was furious, so I planned to force myself inside and return it… but for some reason, after I did, the robot seemed a little more obedient. …Let me stay a little longer. Because the temperature, moisture, and tightness can all be adjusted, it can create a vagina exclusively for me. Using a special artificial vagina that humans don't have, I can orgasm instantly. Afterwards, it even started doing housework for me, and because of its AI learning function, it straddled my penis without permission and even demanded to be inside me. Ah… yes, that's it. This beloved sex doll, neither wife nor lover, will she love me?
