A man works hard out of loneliness, spending all his money to buy a sex robot. He thought he'd bought a state-of-the-art robot with big breasts and a friendly personality, but due to a mistake by the supplier, he received a flat-chested, extremely unsociable robot. He was annoyed, so he intended to just forcefully cum inside it and return it, but after he cummed inside it, somehow, the robot started to listen to what he said. ...I'll stay with it a little longer. The temperature, wetness, and tightness can be adjusted, so I can make it my own pussy. A special artificial vagina not found in humans will make me cum in seconds. Soon it will also do housework, and thanks to its AI learning function, it will straddle my dick and beg for cum inside. Ah... that's it. A beloved doll of desire who is neither a wife nor a mistress, will it love me?
