She wonders if it is a dream; it always starts the same way...
She is a 20-something still living at home with her parents, but she feels in the 'dream' as if she is only 18. She is called into her parents' bedroom by her father; they are all alone in the house. He tells her to take off all her clothes, as what she's done is so terrible she doesn't deserve clothing's protection. Her father tells her to lay across his lap. His arm goes across her chest and his hand holds her breast. He tells her to spread her legs slightly and put her feet on the floor; she can barely get her toes to the floor at the angle she's being held at, but spreading her legs does help. Her father's other arm is draped on her buttocks, and as she settles into the position her father wishes her in, his hand rubs her derriere...then he suddenly smacks her. Hard. She cries out, more in shock and surprise than pain, and feels her father's penis harden underneath her. It makes it hard for her to stay on his lap, as do the smacks her father administers. Soon her ass feels hot and sore, and she is wriggling around trying to avoid the spanking. She notices that she also feels aroused and is surprised. Her pussy lips are wet and she feels an ache deep in her core. Her father's spanks are also getting slower, with long pauses in between them; in the pauses, he slides his finger into her folds, making her moan and move even more on his lap. His cock is getting harder and soon he is no longer spanking her at all. He inserts his finger into her vagina and moves it in and out, rubbing the walls and making her groan and arch her back; his thumb rubs her clit. His other hand is squeezing her breast, twisting and pulling on her nipple, which shoots sparks of desire through her body to her cunt. Her hips are by now rocking back and forth, wanting the ache soothed, somehow.
