Push her (nonexistent) boundaries.

Asami panted as she slowly came down from her orgasm before she sat up, watching Korra as she continued to dance. She smiled, thinking of further ways to dominate her to indulge her newfound genie nature. Given Asami knew first hand just how much joy absolute submission brought a Sex Genie, she wasn't inclined to hold back in the slightest. After all, she knew Korra would welcome a thorough show of dominance wholeheartedly.

"Korra, stop dancing and come over here,"Asami said with a grin. Korra immediately obliged, stopping her dance, and sashaying over eagerly.

"Yes, my Mistress? How else may I serve you?" she asked, a definite tone of eagerness in her query.

Asami simply got up, and started caressing Korra's body, feeling her strong, well trained muscles. Korra cooed at this. "First, I wish for you to get rid of your muscles for now. Replace them with a soft, completely stereotypically feminine body..." Asami smiled. Though she did adore Korra's figure, she wanted Korra to feel completely powerless before her Mistress in this session.

Korra didn't even hesitate. "Yes, my Mistress!" she agreed, snapping her fingers, moaning as the muscles she had worked hard to build softened and shrunk. She didn't even bat an eye as her figure softened. She knew it was temporary anyway, and even if it wasn't, being more pleasing for her owner was well worth it to the genie's mind.

"Next, let's address your hair... I think I liked it longer. I wish for it to be restored to its original length, before the fiasco with Zaheer," Asami noted.

"As you command!" Korra nodded enthusiastically as she snapped her fingers again, not bothered in the slightest that Asami was dictating the way her body was to look. To be honest, she preferred her own hair longer too, she had just cut it for the sake of going incognito for a bit, and found it easier to maintain that way, but that wouldn't be an issue with genie magic. Her hair proceeded to grow back out, and Korra took the liberty of adding the ponytail braids once more, so her hair did look as it used to once more.

"Very nice. You look great," Asami smiled.

"Thank you Mistress! I live to please!" Korra grinned, delighted to do as Asami asked.

(From here, the branches I intend to do will diverge. Futanari will be involved in one branch, the other will exclude it for those turned off by it. The question is, which should be the primary branch? Comment and let me know your thoughts.)
