Treat her like the horny bimbo she's become

"Ha, perfect," Michael laughed as his former son giggled and played with her tits.

The combination of her sweet, simple nature and her sinfully delicious body had Michael pitching a monster tent in his pants. Certainly a vast improvement on the painfully average man she had been.

"Why don't you come over here and show me how much you love your clever Daddy."

David's beautiful face lit up, an image of pure joy at the suggestion, and she bounced across the threadbare basement carpet to kneel at his feet like an eager puppy.

"Yes, daddy," she cooed gazing up at him adoringly, "such a smart daddy, such a caring daddy, such a... Oooh. Such a big hard dandy."

Without needing any further prompting, David pulled her daddy's pants down and cooed appreciatively over his hardening cock.

"*Mmm*, I, *mmph*, love sucking, *guck slurp* daddy's cock!" She gasped between licking and sucking along his full length.

Michael had made her hot mouth for sucking cock, and she did not disappoint. With the aid of an encouraging hand on the back of her head, she was soon deep throating him like a pro.

He fucked her face deep and hard, loving the way her blue eyes stared up at him full of admiration even as he used her like a living fleshlight.

His pleasure soon peaked, and he wrenched free of her lips with a wet pop, in time to spray her eager face with thick ropes of cum.

Michael slumped back in his chair, head trying to catch his breath, while the giggling slut he had made his son scrapped his jizz greedily into her mouth.

As first tests went, he had to consider this a resounding success, and he was only just getting started.
