A man alone. Working up a sweat from loneliness and spending all his money to buy a sex processing robot. I thought I had bought a big-breasted, state-of-the-art, friendly robot, but due to the dealer's mistake, a small-breasted, super unfriendly robot arrived. I was going to forcibly creampie it and return it because it was annoying... but somehow, after creampieing it, this robot started to listen to me a little. ...Let's stay together a little longer. Because the temperature, wetness, and tightness are adjustable, I can tailor it to my own pussy. I can cum in seconds with a special artificial vagina that humans don't have. Before long, she started doing housework too, and with the AI learning function, she even demands to ride on my dick and creampie me. Ah... yes, this is what I wanted. A beloved desire doll who is neither a wife nor a mistress, will she love me?
