Messing Around with my Step Sister – Naomi Woods, Seth Gamble (2016)

Naomi’s mother has got remarried and she has grown up with her stepbrother. He is a spoiled rich kid and they are very competitive. They have just got their results from school, and Naomi is relaxing by the pool when Seth arrives to compare their results. She has taken a bet with him that her results will be way better than his and his car is the prize. However if he wins, he gets exactly what he’s been fantasising about since their parents got married. This may be a gamble that will not pay off for Naomi – or will it?
