Two sheepish stepsisters, Madi Collins and Scarlett Mae, are in big trouble with their stepmom, Lauren Phillips, after causing a small car accident while driving together. When Lauren sits them down and asks what caused the accident, Madi and Scarlett are a bit elusive. After some prodding, it's revealed that the girls got distracted because they were getting intimate behind the wheel.
Surprisingly, Lauren is fine with their intimate relationship but disappointed that they would do something so reckless. When the girls explain that they've resorted to sneaking off to fool around since they thought Lauren would disapprove, Lauren grows sad that they felt they had to hide this from her. The girls are sympathetic and, in an effort to make Lauren feel more included, work together to seduce her. It's time to 'shift into high gear' for a playful threesome!
