Well yes, he is quite old for cuddling! Too old for this, for Lilia squirming in his lap. By far. There is nothing weird about it, of course; Lilia is the man who raised him, though, so maybe this is a bit unbecoming? Malleus, for once, finds himself at a loss for words, as he tries to form a thought as to why Lilia should sit still that would make sense other than the feeble it's strange.

At least Lilia chooses that moment to be the embarrassing guardian figure he has been for so long. Malleus' expression turns slightly sour, which would utterly terrify other students, but for someone who knows him well, it is nothing but a pout. Yes, there's a bit more fang than a normal person, but he is not truly angry. Oh, if he were angry, everyone would hear it.

...ah. Why has he turned around like that?!

"You should not concern yourself with holding or being held by me. I am a grown man," Malleus complains, reaching down to clamp his hands around his waist. "It is simply unbecoming of one such as you to use a lap as a seat, and inappropriate for me to be used as a chair."

That's it, of course.
