All in the Family (2014)

When a woman realizes that tutoring her stepson isn't enough motivation for him to pass his classes, she offers sex as the ultimate incentive. A young woman challenges her stepfather to fulfill her wildest fantasies by leaving him a series of provocative notes, each with their own illicit instructions. After her stepfather becomes frustrated that she's turned his man cave into a make-out location, a young woman comes up with a tempting solution that benefits everyone. A party-going college girl challenges her stepbrother to lead a more adventurous life, only to discover that he's more of a bad boy than she could have ever imagined.
