A good ol' fashioned spanking.

"I know exactly how to deal with you." Holly's father sat down on the edge of the bed. "Lie across my lap, on your front."

"But, dad, I'm naked!" Holly protested.

"You didn't mind being naked around your brother, so you'll just have to deal with it. Remember what happens if you don't do what I say."

"Yes, Daddy..." She sighs.

Slowly she moves into position across his lap, her breasts poking into her father's crotch, where she feels a growing erection. She feels immense shame as her own nipples start to harden, beginning to find the humiliation arousing.

Her dad looks up and down her body, making no attempt to hide his lust, as he stares at her exposed, shaved pussy, thinking about how much better life would be if his wife still looked this hot.

He rests his hand on her left buttock, and she trembles in anticipation.

SMACK.

He doesn't hold back. He hits her fast and hard, causing her to yelp in pain. A red hand mark is left imprinted on Holly's peachy, firm and smooth ass.

SMACK.

"Owwwww!!!! Daddy, please stop, it hurts!"

"If you didn't want me to do this, you shouldn't have fucked your brother."

SMACK.

Another scream. Holly's dad is completely hard by now, his dick poking into her breasts, only separated by his shorts.

SMACK.

Holly's scream is quieter this time, as she begins to lose her breath.

SMACK.

This time all she can do is moan. By now, her pussy is starting to get wet, as much as she didn't want it to, and is terrified of how her dad may react if he finds out.

SMACK.

Another moan. This time though, she can't even tell herself whether or not it is out of pleasure or pain.

SMACK.

This time, there's no doubt, she's hornier than she's ever been, even more so than when she was fucking her brother.

"You've been a very naughty girl, haven't you Holly?"

"Mmm hmmm..." she mumbles, her eyes watering. The way he spoke to her only made her more horny.

SMACK.

She couldn't hold it in any longer, her body erupted in a pleasure she'd never felt before, the sting of her ass a symbol of the fact that she totally belonged to her father now, and would do anything to make her Daddy happy. She let out a throaty, guttural cry as she reached her orgasm.

This time, it was finally obvious to her dad what effect he'd been having on her, as coupled with her noisy climax, he began to feel a wet patch form on his knee, just under where her cunt was resting.
