Proceeds to look like a crazy person. (She is, but that's beside the point, lol.)

Yang blinked and looked around as she found herself in a large, lavish bedroom. It was far more luxurious than she had ever seen... Though that wasn't saying much. She has always been a bit of a country bumpkin, the most fancy place she could claim to have seen was the VIP lounge in Junior's night club (long story). Still, if she were a betting girl (and she was, it was a bit of a problem), then she would say that whatever Ruby's new teammate had wouldn't match up.

As she took in her surroundings, noticing she had her legs back, she walked up to a full length mirror, and took a moment to admire her body from every angle. "Huh, now I really have it going on~!" she chirped, luxuriating in the feel of the silk. She turned from the mirror, looking back at it, and giving her backside a wiggle. "Mmmmm, forget smoking hot, I am a sex goddess now!" she chuckled. She ran her hands through her hair as she turned back to the mirror, admiring the sheen it now had, and the silky feel. Normally, she would have been pissed that her hair was messed with, but she really couldn't argue with the results!

As she did this, more notions flowed into her mind. She was a genie now, a Sex Genie to be specific. A **** to whoever had her lamp. Knowledge on how to use her power also flowed freely into her mind, which expanded to handle the influx... And it brought her great delight to reflect on her situation. Her very nature had changed to reflect enthusiastic obedience. And the thought of obeying a Master, or a Mistress just. Felt. So. Good!

Yang didn't even need to think about her fate. She was already sold on it. And given she knew Ruby was the one who would have her lamp now, any misgivings she might have had about her power being misused, however willingly on her part, were moot. She knew Ruby had a perverted side she kept well hidden, but she also knew Ruby didn't have a malicious bone in her body. She'd probably have to convince Ruby to have fun with this if anything. But Ruby certainly wouldn't go about it in a way that was harmful to others. Even the whole concern about **** was now trivial in Yang's mind. The only reason it was an issue was because of inbreeding, and two girls couldn't reproduce anyway... Well, normally. Her magic could produce workarounds, but it could also ensure no negative defects occured if they ever did have offspring.

With that in mind, she sashayed her way to the bed, and laid back on it, stretching in a manner that would be delightfully seductive if anyone was around to see it. "Come on Rubes, hurry up and rub my lamp already!"

...

"Oi, you stupid bit of bling, you better give me back my sister right now!" Ruby shouted, aiming Crescent Rose at the lamp in rifle form. "You got ten seconds before I start using you as target practice!" She stared at the lamp, keeping her gun trained on it. The ten seconds came and went with the object showing no response.

"...I don't know what I was expecting," she admitted. Indeed, if someone had walked in, they'd have probably thought she was an absolute lunatic, threatening an inanimate object with a firearm. "...alright, you asked for it!" she shouted, pulling the trigger. The bullet struck the lamp, doing no damage, but knocking it over... And also ricocheting off of it, and around the room. "Ack!" Ruby shrieked, diving down just as the bullet whizzed through where her head had been. "...okay, THAT was a bad idea..." she grumbled, getting up once the bullet rolled in front of her face, no longer live.

She scooped up the lamp, looking it over in frustration. She attempted to analyze it for anything she could use to get Yang out of it. Her fingers brushed along it, trying to get a feel for it. That was apparently enough to count as a rub, for it suddenly spewed out the same glittering purple smoke that had claimed her sister minutes ago. She immediately dropped it, picking her weapon back up, but it made no move to grab her, instead starting to coalesce into Yang, looking exactly as she did when she had been sucked in, down to the shimmering violet tail. Her back was arched as she stretched, her arms above her head, her eyes shut, and a smile visible through the veil.

Ruby stared at her own sister, seeing her absolutely divine boobs jutted out and emphasized by the pose, her midriff, flat and smooth with a tight belly button, also drawing a glance. "Oh, that was great..." Yang sighed, before her eyes cracked open. "Well, hello, Mistress!" she cheered, tilting her upper half forward in an unhurried manner, putting her face inches from Ruby's, crossing her arms to push up her bountiful bosom. Her eyes gazed fervently into Ruby's, her own orbs hooded in a manner clearly meant to seduce. "I am the Sex Genie of the Lamp... And I am eagerly at your service. How may I start pleasing you?" she purred, her tone full of lust.
