A girl

"Don't stop," Aiden ordered firmly, and Ellie obeyed.

It was a pretty blonde girl in a classic little black dress; she clapped a hand over her mouth as she caught sight of Eleanor and Aiden, but she didn't take her eyes off of Ellie's hard cock.

"Apologize," said Aiden. "Apologize to her for being so horny and naughty."

"I'm...sorry," Ellie panted, obeying unconsciously. "I'm sorry for being s-so...horny and...nnnnnaughtyyyy..."

"Now ask if she wants to watch," Aiden continued, and Ellie whined but did it anyway.

"Do...do you want to watch me?" she had to squeeze her eyes shut; looking at the pretty girl was too much.

The girl seemed to have regained her composure. "Okay," she purred, and when Ellie's eyes shot open, the girl was grinning at her. She walked over to a crate on the other side of the storage area, took off her panties, and sat down with her legs spread. She hiked a foot up to either side, exposing her wet, bald pussy. She started rubbing her clit, slowly, never taking her eyes off Ellie's cock.

Ellie watched her just as intently. She had such a pretty pussy, and it was dripping wet as she played. Ellie watched hungrily as the girl inserted a couple of fingers inside herself. She picked up the pace, and the girl matched her. She looked up for a moment, and the two locked eyes. The girl grinned again.

Ellie was panting, and her legs were starting to shake. Before she could say anything to Aiden, he leaned in, whispering in her ear, "Put your hand out under your cock. Don't make a mess when you cum."

Ellie cupped her free hand under the head of her cock and started pumping harder. The other girl matched her. Within seconds, with a heavy shudder and a moan she failed to hold in, Ellie came. Her load spurted into her hand, and Ellie stood shaking for a moment. "Be a good girl and swallow it," Aiden said, and Ellie's hand was on its way to her mouth before she processed the words.

She put her head back, opened her mouth, and tipped her hand, letting the cum flow into her mouth. She had to swallow twice to get it all. As she licked her lips and looked back at the girl, Ellie got to watch her cum. She was silent, shaking, as she fingerfucked herself through the orgasm. Ellie stood transfixed, but the girl recovered before long, stood, and sauntered over to Ellie with that smirk again.

She took hold of Ellie's wrist, pulled her hand up to her face, and licked her palm, sucking on each finger in turn, getting the remnants of her cum off her hand. She then looked at Ellie with mischief in her eyes, held up her panties, and tossed them into the corner. "You should, too," she said.

She looked over to Aiden - he gave her a devilish grin and a nod. She gulped, steeling herself, and pulled her panties the rest of the way down and stepped out of them. She tossed them in the corner with the other girl's and let Aiden put a hand on the small of her back and guide her back to the dancefloor.

Ellie knew it wouldn't be long before her cock started to get hard again.
