She wants to touch her father's penis and kiss him
Something inside her tells her not to. And in fact, she knows perfectly well that she shouldn't touch her stepfather. At least, she shouldn't touch him the way she wants to and the way her mind demands. But sometimes, she feels like her hands have a life of their own, because even though she keeps telling herself she should stop, her hands keep moving toward the guy's crotch. She wants to lick those delicious balls, and she wants to have very sensual sex with her daddy. There's no one else in the house, and it's the perfect time for her to start kissing him and arousing him.
