Audrey is very jealous

Brett had almost forgotten about his younger sister, but she reminded him of her presence when she stood up and stomped her way around the moaning duo like a child. She had been in scenes like this before, though, and she knew how to become the center of attention again. She stood behind the couch and leaned over, letter her tits fall into her mother's face. She passed it off as a side effect while she hooked a hand behind Gina's head, bringing her down into a kiss.

Gina kissed her back before realizing what had happened. She jerked her head back and glared down at her sister. "No, you don't get to pretend you're in charge like that, little porn slut." She pointed at the couch next to her mother. "Sit the fuck down and do as you're told," she said, all the while she kept fucking Penny's tits. Her cock was twitching like it was going to explode.

Audrey was surprised by the order, and looked like she was going to refuse. Brett took care of that, making her want to do anything anyone with a cock said. She happily skipped around and sat.

"Good, now you can play with your own cunt while I finish up with this bitch." Her hips were moving faster, her cock pistoning. Penny seemed wracked with pleasure, like she was going to lose her mind.

"I'm... I'm..." Penny couldn't get her mind around the word "cumming," but everyone knew what she wanted to say.

Before she could cum, Brett made himself visible again and stepped forward. "None of you can cum without my permission," he commands.

His mother realizes the truth in his words momentarily. He had cut it closer than he meant to. She looked at him with wide eyes, almost a look of betrayal on her face.

For her part, Gina looked angry. "Who gave a shit like you the right to..."

"Shut up," he said, putting all of the aura of control into his words. He grinned maliciously. "Now, you all have permission to cum exactly when I do. Audrey? I think you might be the expert here on getting me off." Brett dropped his pants, his cock as hard as it had ever been.
