Full Doll and Robot Transformation

Your girlfriend Dahlia has had a tough week, so you offer her a new way to get her mind off of things, an opportunity to be your sex doll. She agrees to give it a shot 

and is transformed into a rigid doll. You train her with the fuck machine, then watch as she orgasms herself out of dollstate. She is dazed, but asks to experience it again, 

craving more. She transforms into a shiny bimbo doll who repeats dolly mantras, then sucks your cock and cums from you cumming on her tits. She snaps out of dollstate 

but begs you to make her a doll permanently, asking you to break her brain and own her. You agree and she transforms into a silver robot doll. She performs chores and 

recites mantras for you, then receives further training on the fuck machine, orgasming in her new, permanent dollstate.
