Yana beautifies Sara and grows her breasts.

Yana chuckled, folding her arms under her chest, propping up her breasts a bit further than the latex suit already did. They really were amazing; perfectly perky, well-proportioned, and large. Sara had been right, Yana wasn't vain... but with breasts this wonderful, she could see herself getting lost in thought, looking at them in a mirror.

"Jealousy is such an ugly feeling," Yana said with a grin, leaning in a bit closer towards Sara. "So let's make sure there's nothing for you to be jealous of."

Sara let out an unintentional sigh of relaxation as a pleasant warmth welled up within her chest... but it didn't take long for her to realise that said warmth was anything but mere simple well-being. It flowed out into her breasts, and there it suffused her flesh, and expanded it. With a surprised yelp, she felt her balance changing as that mass on her chest grew. Her mouth fell open and her eyes went wide, hands seeking up to grasp her breasts as soon as the astonishment gave way to pleasure and desire for more. The heat radiated out through her body, and she felt it flowing through her spine and back as well, strengthening her bones and the muscles there to make sure those new, heavy breasts (or anything else, for that matter!) would never cause any back pain.

Yana held up her hands and placed them on Sara's swelling breasts too, brushing her fingers across the fabric that they strained against. A tearing noise was heard from the seams, prompting Sara to bat Yana's hands away and desperately hold onto her shirt, but their growth came to an end just moments later. The clothes had survived, if only barely, and Sara was panting in astonished awe. Her breasts had grown to match Yana's in size, and they were equally as perfectly perky.

"You only told me you could shapeshift! Nothing about changing others too," Sara managed to stammer out a moment later.

"Actually, you were the one who said I was a shapeshifter. I just agreed with that," Yana said with a playful grin, then wrapped her arms around Sara's torso and pulled her into a tight hug, twin pairs of large breasts pressing against each other. Sara returned the embrace, while she felt that same pleasant warmth suffuse her face and start changing her there as well. Her cheeks had been a bit fuller than Yana's were before, so there was little that needed changing there, but her jaw was adjusted slightly, and her nose as well. Just enough of a change that she was still distinctly recognisable as Sara, albeit a far prettier Sara. Her wavy hair became a bit more voluminous and shinier, as Yana's spell tapped into Sara's latent desires. Within moments, Sara's shoulder-length hair had fallen all the way to her waist. It would require no maintenance, of course - every day, straight out of bed, it would still put a haircare commercial to shame.

"There we go. Have a look in the mirror," Yana chuckled, gesturing towards the nearest bedroom. Sara pulled out of the hug and skipped off with an excited pep in her steps, while Yana followed right after.

Looking up and down over her reflection, Sara couldn't help but feel at her face, just to confirm that this was all real. "Wow..." she whispered, stunned with her own looks, unable to tear her eyes off her reflection. "Thank you so, so much, Yana."

"Oh, please, it was nothing. Anything for a good friend, right?"

"No, Yana. It's a huge thing. It might have been nothing for you and your strange catsuit superpowers, but for me? This is life-changing."

All of a sudden, Sara found herself very close to her friend. The brunette goddess found herself biting her lip, unsure how to respond. "...yeah. I just don't - I don't want you to feel like you owe me anything, alright? I received an immense gift today, and I want to spread the benefits around."

Sara shook her head and grinned, then hugged Yana once more, feeling all that shiny, smooth rubber against her clothes and even her skin. "Right. I'll try not to. Also, your cheeks are all flushed. Are you really that impressed with your own work?"

"Bah! As if you haven't been sneaking long glances at my tits and ass all day," Yana retorted, poking out her tongue.

"Well, I can't take pictures without looking at you, can I? Besides, I'm not into..." Suddenly, Sara's voice became very small. "...not into girls? But you really are quite hot."

If Yana's cheeks had been blushing before, she must have been flaring up now. For a moment she considered suppressing it, but decided against it. "I definitely am. But you're also a supermodel now. And... yeah, you're, uh, very pretty too, I think."

All of a sudden, the two women felt like a pair of youths experiencing their first fling again, and a rather awkward silence fell over the living room as the ultipotent brunette and her blonde friend looked each other in the eyes. It was Yana that broke the silence.

"So are we... are we going to fuck? Because, uh... I could use a bit of relief."

"I'd say no," Sara replied, "but the way this is going, that would be a knowing lie. But like... what do we even do then? I've never pleasured a girl other than myself."

"Right," Yana said, without committing to an answer yet. "Why don't we get on the couch, then we'll see what happens?"
