Your Step-Sister, Nikki Brooks, sits on the couch as you walk in with a remote you found in her room. You try to use it on her, and Nikki stops in her tracks. She explains she’s not your Step-Sister… Not really, anyways. Nikki is a robot your Step-Dad enhanced with his AI programming so you’d have a sibling. You press different buttons on the remote to see what they do, and Nikki’s boobs start to grow huge! She admits she was no regular robot before your Step-Dad changed her programming - Nikki was a sex doll! Nikki’s boobs grow bigger and bigger, and she keeps jumping back and forth between personality programmings. Sex Doll Nikki takes over completely, and sucks your cock until you cum in her mouth, and she sucks up every drop. When Step-Sister Nikki comes back, she is thrown off by what happened, but thinks it may be fun to leave the remote around for you to have more fun later! (Custom Clip.
