Lestat is almost certain Louis did not lock the door. Perhaps, without his own knowing, he neglected that security precisely so he would not be tempted to indulge himself in this.

There is the opportunity to make another idly playful threat in demonstration of his devotion to stave off Louis' anxieties. Parting heads from bodies is beyond him now without the use of a good, sharp edge, but he could always shoot or strangle, or even put his still-wicked teeth to use. But then there would be yet more fussing over unnecessary bloodshed, and he's in too pleasant a mood to spoil it.

He nips lightly at the fullness of Louis' lower lip, employing only the bluntness of human dentation, and laves his tongue over the sting in apology. Louis' fingers find Lestat's throat pressing into them, Adam's apple bobbing in a swallow of anticipation.

"Would you like the door to be locked, Louis?" He murmurs, with a smile. "If it's privacy you want..."

He steers Louis as if in a private ballroom, backing him towards the door with another firm, speech-stealing kiss. It won't keep Louis from talking if his heart is set on it, since it never does, but it is always fun to try.
