A fatherly seduction.

Knowing full well that Marissa is making progress with your son, you spend every waking hour when not in court (or fucking Vessa) with your daughter. She has a keen mind and you enjoy her company tremendously. You're sitting in your study one afternoon when she asks about Lady Vessa, specifically the nature of the mission she was on.

Marissa hadn't gone to much trouble to fill in the backstory, you assume because she had no intention of telling anyone more than they needed to know. You do the same, informing Anna that you can't tell her, but as she looks down you see an opportunity here.

"Well... I suppose I could give you an inkling of the nature of her task." Anna immediately brightens and you wave her over, "Come, sit on my lap. This is a bit of a story."

"Father!" She squirms a little, "That wouldn't be proper! I'm not a little girl anymore."

"No you most certainly are not." She blushes as your eyes momentarily flick down her front, "But you'll always be my little girl. And it is paramount that even this small bit of information be kept a secret, I would rather whisper it in your ear than speak across a room."

She doesn't seem particularly convinced, glancing to the closed door anxiously, but she rises from her seat and settles herself on your lap without further prodding. You arrange her more comfortably and begin recounting the tale of how you met her mother, letting the soft but firm shape of her rump work its magic. She is deeply attentive as you reveal secrets of how her mother had been possessed by a demon, one that had attacked you when the two of you were alone. You speak of how you escaped alive but so did the demon and you sent Vessa after it to keep it contained or at least content not to come after the royal line again.

It was a truly spectacular white lie, given that all of it was technically true except her mother was the demon. She is absolutely fascinated but you notice her becoming increasingly uncomfortable as she shifts and squirms on your lap, inadvertently making the source of her discomfort grow.

When you finish, she's flushed and slightly out of breath. Given how much grinding she'd done upon your lap you wonder at how much of it is embarrassment and how much is actual arousal. You're hoping for an even split.

"S-so that's what Lady Vessa has been doing all these years? Why has she returned now?"

"Well..." You shift yourself again, sandwiching your hard cock between the fabric-dampened curves of her rump, "Vessa was able to contain the demon for many years but we've developed a new means that I expect will contain it for the foreseeable future. And we really needed Vessa back, apparently the courtiers have been getting away with all kinds of magical plots."

"...really?"

You smile genuinely as she doesn't move from her position, her curiosity apparently enough to stop her from immediately vaulting up from her place in your lap. You keep from her the gory details but begin reciting the various schemes and ploys Marissa had disarmed over the years, leaving out the threats to your life partly not to frighten her and partly because you'd only just learned of such events yourself.

You begin repeating this little ritual more and more often: her sitting in your lap as you regale her with stories of your life as king. She gets more comfortable, prompting you to follow suit, and after about a week there's little doubt that anyone entering in on the story-time's would be thoroughly aghast at the grown princess faintly rocking in her fathers lap. There are stretches of silence, punctuated only by your occasional grunt or a gasp from Anna, that make you realize you are essentially already having clothed sex with your daughter.It's altogether rather pleasant, and Anna never comments on the wrongness of it though she's clearly aware. She begins to change her behavior around you ever so slightly when the two of you are alone, the faintest hint of flirtation, bending over unnecessarily to reach books and the like. You're almost content to simply enjoy the gentle teasing from your daughter and fuck Vessa senseless every night thereafter.
