After Spike puffed up into the new lovely dragoness they became, of course one of the first things she did was pay Rarity a visit to show her new self off to the mare she always loved greatly. Needless to say, she was in shock and awe with how gorgeous, beautiful, sexy and BIG Barbra was, and how STACKED and voluptuous they were too, and within such lovely rubbery garbs as well! Such would drive her to ask how it happened, before Barbra would tell her the full story. Once she heard how it seemed to work, and realizing what such could do for her, she would soon pull Barbra in to give them what they always wished from her: A deep, passionate kiss on their muzzle. It didn’t take much long after that to convince her once “spikey-wikey” to puff her up grandly as well. I guess some things never change for that dragon, even when a towering giantess…
 
Some time later, we can now see Rarity now sporting one of her new line of BIG rubbery gowns, stitched and sewn together by her and made of both vinyl and latex, with a lovely sapphire gemstone in the middle to complete the look. She wished to be a proper lady even like this now, and as such she WOULD have proper garbs on her beautiful body! So with herself fully set, as she would enjoy soon a night in Canterlot, she would soon perhaps see you looking or gazing at her, as she gives you such a sultry smile knowing you likely enjoy what you see with her. And if you treat her like a proper lady, she might even let you dance with her later that night…or perhaps do even more when the night’s events are almost over, if she feels you’re a proper gentlecolt in her eyes…~
