Sally was sobbing with ecstasy as her brother rammed his cock in and out of her cunt, going deep. She arched her ass to him with wanton excitement, lowering her head and shoulders to the floor.

"That's it, Sally!" Marla cried out, shoving her hand back to her daughter's tit. "Shove that pretty ass back! Shake your hot ass, Sally! Ohhh, Bob, shove your hard cock up her cunt! Fuck the piss out of your sister's hot, wet cunt! Oooooh, Sally, you have such hard tits! They're wonderful titties, baby!"

Clutching her son's balls, Marla licked her tongue about her daughter's creamy, shivering hips, running it down to her thigh, then back up again. She licked over one cheek of Sally's hot ass, swirling her tongue wetly. She inhaled the exciting scent of her daughter's wet, hot cunt and her son's hard cock. Her cunt was steaming and she was becoming drenched in the crotch of her panties. Her own clit was protruding with hardness.

Bob was grunting as he thrust his cock back and forth, feeling his sister's cunt grip him with wet heat. The way his mother was pulling and twisting his balls wasn't helping his control any.

Marla, drawing her face back, found she could see her son's cock plunging into Sally's cunt. She could see the tight way those sugary pussy-lips clung to his hard prick. She breathed hard, her pointed tits swelling inside her blouse. "Ohh, Bob!" she wailed.

She grabbed his hand, pulling it from his sister's gyrating hip. She curled her son's fingers around one of her tits. Bob gasped as he felt his hand filled by his mother's rounded tit, and looked at her.

"Ohhhh, feel it, honey! Feel Mother's tit, but keep fucking your sister!"

Bob, intensely excited, began to squeeze at his mother's tit, feeling it through her blouse, lunging his hips back and forth, ramming his cock into his sister's clutching cunt faster and faster.
