Roger is offered the trip of a lifetime to Europe by his father—but there's a catch. He must first endure eight days trapped in a secluded mountain cabin with his father and his beautiful stepmom, Gwen. What sounds like a simple family getaway quickly turns into a trial of willpower.

Gwen used to be his nanny, but now she's married to his dad, making her strictly off-limits. However, the forced proximity of the isolated cabin, combined with long, intimate trails and shared spaces, stirs up deep, forbidden desires in Roger that he desperately tried to bury.

As the days pass, the tension between Roger and Gwen becomes unbearable. She is effortlessly seductive, and the mountain air seems to fuel their mutual attraction. The boundary between family and fantasy starts to blur, threatening to shatter their family dynamics.

Roger thought he only wanted a vacation in Europe, but this Vacation With My Stepmom is leading him down a path far more dangerous and thrilling—one where forbidden desire is the only destination.
