A free-for-all

"I want to be able to change Dani at will," Eric said. "I want to have the same power over her that you do."

"Wow, great idea, hon!" Dani added. "What are you gonna do, make me stupid? Oh, and Kat, this is what you want, right?"

Kat nodded. "For now. Anything Eric says he wants, you can assume you're doing it for me."

Dani turned lustfully to her boyfriend and let the towel slip down into her lap, revealing her breasts. "Well?"

"Can you be sexier?" Eric asked. She smiled coquettishly and leaned in close to whisper to him. Her breath was hot on his neck and he felt himself stiffen slightly.

"Definitely... wanna do it in front of Kat?"

Kat burst out laughing. She'd known Dani for decades and she had never seen her act even remotely like this. Dani was a complete nerd; she was attractive, but she was never sensual like this. She didn't seem to mind the laughter, though. She reached out and began unbuttoning Eric's shirt.

"Kat seems to like it," Eric said. He looked down as her fingers deftly unhooked another button. "Um, can you keep being sexy but not talk? I want you to seduce me with just your body."

"Good choice!" Kat said. She leaned forward and watched with interest as Dani slowly unzipped Eric's pants with her teeth. Finished, she pulled off his pants and underwear in one motion. Eric was now nude on the bed and Dani was on top of him, her eyes locked with his in a sultry stare. She reached down to stroke his erect member and he let out a little groan that Kat chuckled at. She was still observing keenly, curious to know where Eric would take it.

"Oh, God, babe, that's incredible! But Kat wants to experiment, so what should I have you do... I know! You should love me and care for me second only to Kat. You should consider her the boss and me her right-hand man and yourself as... an unpaid intern."

She nodded, absorbing this new information. She shot Kat another questioning look.

Kat gave a thumbs-up. "I wanna let this play out."

Dani turned back to Eric. She stood with her hands on her still-bare hips, waiting patiently. Eric was distracted by how hot she was and thinking about what he could do to her. Kat gently prodded him. "Say something. Tell her to do something."

"Umm... I don't know, be sexy."

"Booo!" Kat said and his heart rate spiked. "You already said that! Do something different!"

Eric panicked. He tried to think of something Kat would find interesting. He saw the same panic on Dani's face. Her eyes wide, sweat glistening on her brow. The smell of the sweat on her skin brought back a flash of memory and he knew what to say.

"Dani, please come."

Dani's eyes widened and her nails dug into Eric's flesh. She opened her mouth and let out a high- pitched wheeze before collapsing onto him. As she quietly writhed, Kat shot Eric a look.

"You can talk again!" he cried out and suddenly her ear-splitting wails faded in like someone turned up her volume knob.

"...ahhh fuck oh fuck oh GOD OH FUCK ME-" she froze, the veins on her neck taut as cables, then let out a long, satisfied sigh.

"Oh my God, Eric, that was- like nothing I've ever felt." She was being sincere, knowing that he'd fine it incredibly arousing. Kat wanted what he wanted, and he wanted sexy.

"I can't believe I'm saying this," she panted, "but... more."

"More?" he replied doubtfully. Kat a gave a goofy grin and a thumbs up and he nodded. "More."

Suddenly she was looking at her knees and it felt like little metal spiders were running up and down her thighs, like thousands of tiny pinpricks. She doubled over, her thighs almost painfully tight, and grunted. "Ahh- Ah!" It hurt a lot, but it felt great too. It was what Kat wanted, though, and she definitely didn't mind doing it. She could almost forget about the pain of her overexerted muscles and drift away into euphoria. She closed her eyes and pictured herself falling through clouds, the earth miles and miles away, like she could fall forever...

Then something fuzzy was pressing at her head. She opened her eyes and saw the sideways image of her boyfriend and roommate looking at her with concern. She was laying on a fuzzy blanket. "Are you ok?" Kat asked.

If she wasn't, they could worry about it later. She didn't want to stress Kat out. "Yeah," she rasped. "Great."
