I remember the story starts out that a husband and wife had just finished up pretending she was a robot. She had a suit on that made her look like one and a chip that when active would override her. She was still dress this way with the chip active and someone else came home and mistook her for a regular robot then figured out she must be a sex bot. I remember she tried to hide in a garage, but was found there.
Because the chip was still active that person was able to control her. I believe it was a multiple part story, maybe 5-10 chapters. Eventually some of the things she was forced to do started to imprint on her because the chip isn't supposed to be active for days.
Any help finding it would be great.
