DDOB-030 Humanoid onahole built to look like the professor's wife learns to cum from vibration, fingers and a 3P finish

A professor whose wife left him builds a humanoid masturbator that looks exactly like her, fitted with an AI learning function for rhythmic stimulation. The final experiment involves M-shaped restraint, lotion, rotors and electric vibrators, making the doll livelier than a real woman. With an assistant and the professor, the doll is trained through continuous vibration, finger play and W-shaped stimulation. Advanced learning leads to a vaginal creampie 3P as the experiment's last item.
