First some body alterations!

Korra then suddenly gasped as she felt her clitoris burning in a pleasurable, otherworldly way, almost the moment she returned to being human. She then remembered that Asami had wished for whoever was the Mistress to have the cock. "Oh..." she panted, the feeling being amazing. Slowly, her clitoris grew out into a new futahood. She smiled when it finished growing, and ejaculated a spurt of semen onto the floor, making her gasp in delight.

The member remained hard, and she gently grasped it in her fingers, and began to slowly stroke it. She then shook her head, clearing her lustful haze slightly. She had a much better way to handle her arousal right now! She picked up the lamp, looking at it longingly. Why, oh why did Asami have to free her before listening? Though a part of her was happy to share the experience with Asami, she really wished she could be the genie full time! Oh well, no use crying over spilled milk. She rubbed the lamp, and sure enough, Asami was released from it.

"Took you a few minutes," Asami pouted playfully.

"Bite me, you're the one who decided on us growing dicks upon becoming the Mistress," Korra smirked.

"...true enough, Mistress," Asami conceded with a giggle.

"And speaking of changes to our bodies," Korra noted, running a hand over the arm holding the lamp, noting that her muscles were still gone, replaced with soft, stereotypically feminine flesh. "I wish for you to restore my muscles!"

"Granted, Mistress!" Asami smiled as she snapped her fingers. Korra moaned as she felt her hard tissue and strength return.

"Ah, much better," she grinned. "I didn't mind losing them as a genie, but I prefer having them as a human. Better to keep the soft body for when it's my turn to be dominated. In fact, I wish for my genie form to lack muscle, but my human form to automatically regain it."

"Done!" Asami snapped her fingers again. "So, what next, Mistress?" she purred, leaning forward, eager to be bossed around. "It's your turn to make me your bitch..."
