Marla slowly came down from her orgasm, her hips lowering. She pulled her finger out of her cunt, and her face glowed with pleasure. The fog lifted from her eyes.

"Oh, that was very good," she mewled, grinding her hips from side to side lewdly. "I can't get enough of it! I love to come!"

It was then she noticed her daughter was still clinging to Bob's cock but not moving her fist. Sally knelt with her knees, spread wide, leaning down to hold Bob's cock. Bob, leaning against the chair his sister had been sitting in, had his hand under her skirt.

"Don't stop, please," Marla gurgled. "Let me watch you! Please, I want to see you. I'm sorry if I frightened you, but I can't help it!"

"You really mean it, then, Mom?" Bob asked.

"Oh, baby, yes!" Marla hissed.

Sally giggled softly and pulled her hand from her brother's cock. She remained on her knees as she lifted her skirt to her waist. Marla gazed at her daughter's cunt.

"Oh, that's so pretty, Sally!" Marla moaned as she stared.

Sally had few hairs on her cunt, and her sugary pussy-slit was fully exposed. Even the tip of her clit was seen peeking out with provocative hardness, wet with her sweet fuck-juices.

"Mother, I want Bob to fuck me," Sally said, her voice trembling with emotion.

"Can he? Will you let Bob fuck me, Mother?"

Marla sucked in air, her tits thrusting out, her nipples pressing at her blouse. She stared at her daughter's succulent cunt with steamy eyes.

"Yes!" she cried out. "Oh, yes, yes!"

Bob's cock jerked up and down as he leaned over and looked at his sister's cunt. When he turned to look at his mother again, his eyes went immediately to Marla's hairy pussy.
