When I came home to find my personal sex robot masturbating without permission, I was surprised. She had never exhibited this sort of behavior before, and her manual never indicated that it was even a possibility. She was designed to be as lifelike as possible, and I guess my neglectful behavior had prompted her to run certain system processes without admin approval. As they say, most computer problem's are caused by user error, so I figured I need to use her properly to help get her back into her normal programmed routine. She was also due for some maintenance. The manufacturer had provided me with a special oil to protect the dermal coating so I rubbed that all over her body before tying her up and making her orgasm manually. As I stroked out every last drop of cum, I could see that she seemed glad to be well taken care of, and eager to continue pleasing her owner.
