An overly religious step mom accuses her sister in law of being a sinful influencing on rebellious step son. Auntie has been her making good use of her step nephew's horny cock, and will absolutely not let the young man be taken away. Auntie uses a tv screen to entrance and brainwash the jealous step mother, implanting hypnotic triggers to instantly make Step Mommy their obedient sex toy.
They toy with their mindless bimbo, juggling the slave in and out of trance. Step Mommy's lucid moments of confusion and panic only encourage them to command her into deeper depravity, gradually implanting her disappearing mind with permanent commands.
Step Mommy returns the next day, immediately stripping to her lacy lingerie and deluding herself that she is following God's will, not just her owners whims.
A week later, Auntie surprises her boy toy with their now completely transformed, Godless heathen.
None of the sinners have ever felt happier in their lives.
