And then there's Sebek:

she looks so much tinier than usual here what the heck

I could see Vesper and his Queen wrapping their tails together to make it feel more intimate and loving. Aswell as teaching his Queen how to take care of their neck floof.

Def overstimulating them by licking or kissing their antennae.

I see the wings as being like one of those floofy blankets that keep you warm and just them wrapping their wings over him to snuggle and keep warm.

[You almost described that one moth girl from an FNF mod.]

It's pretty rare for such a wild transformation to happen, but then again, you're dealing with Icons, and Icons are often total mishmashes of characteristics compared to their more physically homogeneous subjects. So really, it could happen!

Vesper's not just going to teach you to groom your fluff, he's going to tell you how to use it your advantage. You have scent glands in there, you know? The King himself is drawn to them, shoving his face in any fluffed part of you he can just to smell your pheromones. You're even more irresistible, he can and will get high of them.

In fact, you're taught how to mark people with your fluff. Though you can only do that to Vesper mostly, just as he marks you with his own. In fact, you're going to have to endure Vesper rubbing himself on you like a needy house cat just so he can have your smell. You can also sell your fluff for a lot of money. Ludicrous amounts, really.

Vesper is also in love with the fact that you have something similar to his "whiskers", though your antennae are a lot more sensitive than his lashes. He's not just going to lick them, Vesper will take both into his mouth and suckle until you're spasming and paralyzed in sensation. It's one of his favorite things to do, because it leaves you open to all sorts of stimulus.

I'll be honest, anon.I don't ship it, but I won't deny, it's cute.
