Not entirely

There are no way you can do the same thing as protagonist of your story did. You always knew the line between fantasy and reality and you are sane enough to not cross that line. Yet, you decide it can't hurt to make your fantasies brighter to enchant those with the feel of how your daughter feels. Ignoring (as much as it is possible) the pressing need to do something with your boner you kneel down and start kissing Jenna's exposed breast before taking her long nipple in your mouth. It has been years, more than a decade actually, since you have experienced anything involving tits so young and fresh. Women of your age may have larger ones but this kind of taste can come only from someone as young as Jenna.

Jenna answers to your tongue with soft moans. She must be seeing some wonderful dream. There are no chance that she'll remember it but you are happy that you are not the only one who experiences pleasure. Out of curiosity you move your hand down and slide it in her panties to find that she is indeed enjoying it. Not thinking twice you slide a finger in and start rubbing from inside without stopping your licking and kissing of her upper body. "Yes! It is so good" She moans in the sleep without even coming close to awakening

At some point you make a decision of what you want to do. You reluctantly pull yourself away from your sleeping daughter and then pull her panties down revealing her delicate cleanly shaven pink pussy glistering with wetness. Then you move her to the edge of the couch, spread her legs wide and go down on her kissing her labia.

How different you actions to ones described in the story. Instead of violently pounding her sex with your dick, you gently and carefully penetrate her with your tongue receiving louder and louder 'yes' moans coming from her sweet lips. Then she doesn't even give you a chance to go for the most enjoyable part - playing with clitoris. Before you do that her whole body trembles the loudest moan yet come out of her. Your daughter has orgasmed and you don't know if it is a good or a bad thing that she'll never know that her father eated her out so well.

You may have given her body what it needs. But yours is far from being satisfied and you need to do something about it.
