Marla lifted her face, her eyes glittering.

"I know, baby," she whispered huskily. "And you can have it."

Squealing, Sally peeled her shorts off swiftly, dropping them to the floor. Bob was pushed into his chair by his mother, who dropped to her knees. Sally stood waiting, puzzled.

"There's more than one way to get a cock up your sweet cunt," Marla said, understanding her daughter's expression. "All you have to do is straddle Bob."

"Ohhh," Sally cooed as she swung a leg over her brother.

From where she was kneeling, Marla watched her daughter's sugary cunt flash briefly, then shoved her hand to her son's cock. She grasped it as she had the night before, leaning forward to watch his cock penetrate his sister's lovely pussy.

She gripped her brother's shoulders, making hissing sounds. Marla moved her other hand to her daughter's cunt, feeling the wet heat of her pink pussy-lips. She rubbed the head of her son's cock back and forth, dragging it along her cunt-slit. Sally gurgled with the contact, humping her ass as though trying to get her brother's cock into her cunt.

Marla understood her daughter's eagerness, and placed the head of Bob's cock at Sally's pussy.

"Sit down on it!" Marla groaned as she stared at them. "Sit down on his cock, darling!"

"Oh, yes!" Sally cried out, lowering her ass. Marla held her breath as she watched her daughter's pretty cunt stretch about the smooth head of Bob's cock. Her cunt, already hot and wet, began to pulsate as if she was about to come. Seeing her daughter settling onto Bob's cock sent shivers of perverse pleasure throbbing through her naked body. She let her breath out with a soft hiss as she saw Sally's pretty cunt stretching, being stuffed with Bob's hard cock. She hooked her finger into her son's shorts and pulled them away, exposing his tight balls.

"Fuck him!" Marla hissed. "Fuck his cock, Sally!"

"Ohhh, yes, Mother!" Sally sobbed, and began lifting and lowering herself on Bob's cock. "Oh, it's so good! You're so hard in me, Bob! Oooooh, I can get your cock so deep in my cunt!"
