Il marito cattivo mi tradisce con la babysitter, quindi devo punirlo

The babysitter is on the couch as the stepfather comes home. After their last adventure both have no hesitations, and start kissing right away. Both get nude, and at the same moment, the wife comes home after being at a BDSM party with her slave. She is shocked, and she gets very angry, but soon sees an opportunity to satisfy her desires to humiliate her cuckold slave.
