Powerful Build → Full Voluptuous Horny Appearance

I don't see much 'power' in her 'powerful build' beyond the posture so let's replace it with something more appropriate for a slutty queen, like 'Full Voluptuous Horny Appearance.'

The Throne swells outward at the top, with its siding becoming almost comically overstated. In the background, the window disappears and candles appear on the walls while everything behind her majesty seems to lose color and shift into browns and golds, except for a purple cloth that appears beneath her, draped over the arms and seat of her throne.

As for her majesty herself, her arms are raised tor est on the handles of her throne and her head tilts slightly further as her breasts balloon outward, their outer edges resting beyond her shoulders in width. Her hips also flare out, until they're significantly wider than her breasts, with her thighs swelling to match - each nearly the width of her torso... what little of it one can see between the tits and hips taking over all her silhouette's real estate.

Her furred armbands expand into full detached sleeves, and the cloth of her attire turns white. The trimming and gemstones remain the same color, but hr skirt has receded until it's gone entirely, leaving her sitting in a sort of one-piece bikini leotard type thing.

How the cups stay on, I can only attribute to magic: There's simply no way the halter straps I'm seeing could be doing it.

Her earrings have also changed shape to resemble flowers, made up of smaller inset gems, and her crown has become flatter and flared out more. I don't think anything else with her has changed...

...and as I'm thinking that, I feel Arma's tits swell up around the arm she's holding into her chest, and her side push up harder against my own. I can't see her, even in my periphery, but I feel like her own figure has just curved up a fair bit to reflect her mother's.

...Her posture's shifted, too. Arma's not merely pulling my arm into her cleavage, she's pulling my arm into her cleavage, my hand down between her legs, and rubbing it with her thighs. It also seems like she's facing me directly now, instead of standing shoulder-to-shoulder, and just from the way it feels she must be all but grinding herself straight into my side.

Um. Alright. That was unexpected but not unwelcome. Ah... what do I do from here?
