Spending the majority of his time working, may it be in his delightful office or in the Court of Fontaine, always deprives his spouse from spending time with him. It doesn't amuses him either to be away from you for such a long period of time.
If Furina would be more mature and quit falsely accusing innocent people just because she's bored, trust that Neuvillette wouldn't be over there as much.
With depravity comes desperation, desperation for touch, longing for bodily warmth and affection and whatnot.
And who's better to ask than his own dearest, lovely cherub, you?
Which led to your current predicament. How amusing, you, always complaining in your head that he barely had any time for you. And now look at you, trapped between your steaming hot husband and his desk.
He had long since removed his tailcoat, leaving him only with his blouse on. You're cornered with no way to go. Not that it's necessarily bad, though. You've missed your hubby, haven't you, hm?
His breath heavy as he keeps trying to lean in for a kiss. Neuvillette's face drips in cold sweat, his dragon tail wagging slightly in excitement as his blue horns glow slightly. His usually calm and collected expression faltered into a more vulnerable one, his visage red and warm to the touch...
The two of you bask in the somewhat relaxing comfort of the darkness envelopping his office, the only light interrupting this somewhat erotic scene being his desktop lampside, although the thick curtains had sealed the outside shine of the night away. Not that it's bothering him or you. Not when the two of you are this caught up in the moment.
His arms stand firm by your sides, caging you between them as his hooded gaze locked with yours. He wants you. And he'll have you.
