For years, Lily mercilessly tormented her step-daddy Jake. Wearing too-tight shirts, and too-tight shorts and towels that barely covered herself. But she never meant anything by it. Not really. She's a good girl, he's a good man, and he's helping her pack for a big move out of state to begin her belated freshman year of college. When she's walking down the hall, she hears him doing something she never imagined. In between heavy breaths, he's saying her name and saying the most wonderfully dirty things she's ever heard.

One morning, when eighteen-year old virgin Ana wakes up to see her step daddy Peter outside, shirtless, chopping at a tree, she starts to feel something naughty, something she's never felt before - a sweet, tingly feeling between her legs. But she knows her daddy would never, ever do anything like that... no matter how bad she wants it. But, when they take a bus trip to the hardware store, she learns that she's not the only one who has been having dirty thoughts.

One night after she leaves, he hears his step-sister Addy moaning his name from downstairs and decides to see if she's been holding on to the same long-buried fantasy that he's been nursing for years. He finds sweet, virgin Addy asleep, but when he gets close, she reaches for him, calls out to him, and like any good big brother... and helps himself to everything his sister wants to give him.

She can't stop thinking about her stepdaddy Paul. Ever since he married her mom, she can't get his brawny good looks and firm-but-gentle personality out of her mind. First, it was silly crush. These days though? It's gotten so bad that every time she takes a shower, she just can't help but imagine what it would be like to have him, to be with him.

Gia is a good girl. The sort of good girl who won't even drink when she goes out to a bar with her girlfriends at college, and hasn't even let a boy get too far with her. Of course, she's also the sort of girl who has fantasies so naughty, so taboo and so wonderful that she'd never dream of telling anyone about them. Since she was little, she's been surrounded by love, care, and attention from the two men who were her stepdaddies, first Ben and then Drake.
