" - How?"

By going around behind Lily and putting hands on her again, of course.

Nnn!

She has even more mixed feelings about this - she's exhilarated by the success, the praise, but still feels humiliated about the Demon Queen's earlier reaction to her thinness - but it's difficult to be anything other than happy, excited about her wings, about her teacher admiring them...

She pushes into her teacher's hands a little, with a small sigh, wings rustling.

She makes sure the wings are rooted, traces the new interplay of fibers across the back... and around to Lily's chest, where she lets her hands wander a bit farther.

Squirm!!!

Especially as the Demon Queen's arms wrap around her - the wings make physically moving around her very awkward, so the best angle here necessitates the Demon Queen pressing against Lily's back - Lily shivers and makes a small, needy sound as her teacher's hands move from curling around her waist to brushing up her sides, to where her muscles connect in front - and an almost indignant squirm as those hands skip up to feel along her collarbones, investigating the shoulder girdle near her neck... 

"Be still, child."

"I'm not a child."

"Perhaps not..." She drops a hand to cup Lily's breast.

!!! Yelp!!!

"Is this not what you want?" she whispers.

"Ah - " She shivers, and almost experimentally pushes into the Demon Queen a little. Then, very very quietly: "I want this."

Then the Demon Queen will take.

And what she receives is soft, needy sounds - sometimes reluctantly, often eagerly, sometimes both at once. She receives Lily pushing into her, Lily's hands on her arms, Lily's feathers fluffing out like the fur along the spine of a startled cat. She receives Lily leaning her head against her teacher's shoulder, face turned invitingly up - too short to reach the Demon Queen's lips on her own, not without dragging her teacher down. She receives a Lily that's getting a bit frustrated about their positions and her wings making it hard for her to touch back, too, and a Lily that's revelling in the focused attention. And, as she takes more and more, she gets an increasingly squirmy Lily, one contemplating trying to squirm out of her pants - or trying harder to squirm into a position she can touch the Demon Queen properly from. 

Oh fuck, she meant to stop before this.

"Enough," she says firmly, releasing Lily and stepping back.

- ?!?!

Offended squawk, and her wings flare up as she spins around - the Demon Queen probably won't have to duck but she may want to step back more. 

She does so, regarding Lily impassively.

Her eyes narrow. "Don't tease me," she says, warningly (trying to cover up how she feels somewhat hurt). 

"This is as far as I am going."

"Why?" Yeah she definitely feels hurt, but maybe she'll feel it less if she buries it under an indignant huff.

"Because-" I care too much. "-You are too young."

There's an emotion in her chest, one with fangs that sink into her heart, one that spreads like venom through her veins - it's too big for her, overwhelmingly so, and the times she's had to grapple with it before have been - tough.

She thinks it might be 'pain.'

"Too young?" she snaps, utterly failing to sound offended and not like the Demon Queen just reached in and grabbed one of her deepest fears. "Old enough to taunt, but too young to - "

"Too young to taunt, in truth. I was... carried away."

"I'm old enough to want it. And I'm mature. I get what - adult concerns - are. And I don't want to be treated like a kid." That last comes out far more raw than she intended. (She feels... Almost desperate. Something nearly like being scared.)

"This is my line it's not- any other quality of yours."

"But why?"
