The girl was rewarded with a deep and sudden groan for her efforts.  As her lips descended down over his length once more, Paul was compelled again to watch, to drink in the sight of Celeste's devotion as she took as much of his length as she was able.  On another day, if she had to be punished, he might try to push those limits a little, but for now his Celeste had been a good girl - a very good girl indeed - and so this time was for the intimacy they could share, and the pleasure they could grant to one another.  As he was reminded of this fact by a glorious lashing of her tongue across the lower side of his shaft, Paul struggled to gain enough focus that he could return a little of the favour.  His left foot, upon which Celeste was straddled so boldly, began to shift just slightly, moving back and forth by perhaps a quarter of an inch.<br/><br/>When she looked up at him, it was impossible not to see the look of plain passion in his daughter's eyes, even while his length was sucked faster and harder past her perfect lips.  Paul's hand came to her head, and he began to stroke her scalp affectionately.  "That's it, baby.  You're so good to Daddy.  You're such a good girl, a perfect girl.  You make Daddy so happy when you show him that you love him like this, baby."  Even as his words spilled from his mouth, the subtle and now-familiar flavour of his pre-cum entered Celeste's.
