Yes

"Fine," Yang said.

Ruby swallowed. "Okay."

They started for the cage when Weiss held up an arm. "None of the animals I tested had clothes in there with them."

"What?" Ruby asked.

"We have to replicate it perfectly."

"You're kidding," Yang grumbled.

Weiss raised an eyebrow.

"Fine," Yang said, unbuttoning her shirt. She lifted it up to reveal her bountiful breasts, which bounced gloriously. Ruby stared, her mouth hanging open for a few seconds.

"You too," Weiss reminded her.

Slowly, the sisters started undressing. They could hear small giggles from the Huntresses and female professors in the audience, and they tried to block it out. Ruby felt more humiliated with each article of clothing she undid. Yang felt belittled the more the draft enveloped her body.

Then she sisters' hips touched, bare skin against bare skin. They both gasped and looked at each other.

"Do you want to give a show?" Professor Goodwitch asked. "Or do you want to get this over with?"

Blushing, Ruby and Yang resumed undressing until they were both naked in the stadium. Weiss stepped aside, smiling smugly as she opened the door.

"Have fun," she whispered as they passed her by.

Then the door was closed, and Ruby and Yang were naked in a cage, about to have sex in front of an audience. Yang stepped closer to Ruby, her breath brushing against Ruby's lips.

"Let's just... do it," she said, her voice shaking.

Ruby nodded. "Let's."

They shook as they got closer, Ruby's breasts brushing up against Yang's. They looked into each other's eyes.

Then kissed.

Yang held Ruby's head close as their tongues danced with one another. Before long, Yang pushed Ruby down on the floor before rubbing her knee against her crotch. Ruby gasped, breaking the kiss momentarily. Then she wrapped her legs against Yang's so that she could share in the grind.

Ruby reached up and grabbed Yang's breasts. They were so soft and pillowy. Yang retaliated by rolling over so that Ruby was on top. Once there, Yang ran her hands along Ruby's hips before squeezing her cheeks. Ruby gasped again before breaking the kiss.

"What... what're you-?" Yang asked before getting her answer. Ruby put her face between her breasts before licking Yang's nipple. Yang gasped as the sensations sent spasms across her body.

And there the two half-sisters lay, having sex in front of an audience for what seemed like hours, though it was really thirty minutes. They climaxed multiple times - probably more than was necessary to break the effects, but Weiss wasn't going to tell them that. By the time they were done, the conference was over, and the guests had left.

Ruby and Yang lay naked and sweaty, collapsed against each other within the cage. It was now literally steamy in there because of their activities.

"Well, looks like you did it," Weiss said, cracking open the cage. "You never have to worry about the E.N.A.B.L.E.R.'s effects ever again."

Yang groaned as she sat up, stopping to shake Ruby off of her (she was still suckling on her).

"I can't believe we just did that," she muttered, now grossed out at the sight of her naked sister.

"Yeah," Ruby said, sticking out her tongue to get the taste of Yang's nipple off of it. "And in front of so many people."

"Well, it was only a couple dozen people," Yang said. "At least there's that."

Weiss's eyes widened. She looked at the camera that had been recording the presentation for other conferences across Vale.

Live.

"Yes," Weiss said stiffly. "Only a couple dozen."
