After a bit of harem talk.

After about ten minutes, they sat together on the desk, Ruby on his lap, her tail back again, and both still naked. "That was awesome, Master..." she purred, tracing his chest with her fingertips.

"It was," Jaune nodded. "Though I could have done without the interruption."

"You kidding? Fucking in front of Weiss was hot!" Ruby grinned. "So, do you want her?"

"Er, what?" Jaune blinked, not sure he had heard her correctly.

"You know, do you want her to be yours too?" Ruby asked. "She's pretty sexy... Or perhaps you'd prefer my smoking hot sister? Or maybe your attractive, and popular teammate!"

Jaune went absolutely beet red. "Whoa, whoa, wait a minute!" he protested. "That sounds quite unethical! Not to mention, I already wished to be unable to take anyone against their will! Besides, we're essentially together now! I wouldn't cheat on you!"

"Master, you underestimate just how sexually driven humans actually are," Ruby smirked, nuzzling her head into his chest. "It's hardwired into us... Moreso with me, since I'm a genie. It's all just buried underneath our upbringings, societal rules, social and legal norms. Humanity tries to elevate itself over the animals we are at our core. Sure, there are legitimate moral concerns with being completely sexually uninhibited, but believe me, everyone would be happier if they could more freely explore their own sexualities. There's literally nothing wrong with any sexual act that happens between adults who consent, we've just gaslit ourselves into thinking there is due to the societies we grew up in. Nothing you do has to be against anyone's will. You would be surprised just how many people would willingly, even gladly go along with being part of the harem of a Sex Genie's Master if they didn't have their inhibitions in the way. It's just a matter of knowing what their truest selves actually want, and offering it to them."

Jaune's mind raced. "But what about the whole cheating thing?"

"Master..." Ruby giggled. "It's only cheating if you're breaking rules established between yourself and your partner, going behind their back. But I think we established by now that as a genie, my primary source of happiness is your own. I don't have any rules you could break. In fact, I would very much love to bring more girls in for ya! It also helps that Sex Genies are bisexual by default, and I already was bi before anyway!"

"...okay, we can think on this... But perhaps we should call it a day," he ultimately decided. "I'm... Pretty much overwhelmed for one day as it is."

"Alright!" she grinned as she floated off of his lap, and once again reformed her legs, snapping her fingers and magically redressing herself in her genie garb. Jaune meanwhile out on his own clothes, and they headed back to their respective dorms.
