Marlene rubbed her open mouth from side to side on her sister's cunt, crying softly as she tasted the creamy juices seeping from it. She waved her pantied ass about in the air, unaware that her nephew was watching.

Timmy stared at his Aunt Marlene's ass, his cock bulging against his pajamas. The tight panties had crawled over his aunt's tight ass, and he could see the white flesh where it joined the tan of her thighs. Since Marlene's panties were sheer, be could see the crack of her ass. He could see the dark hairs of her cunt through the tight crotch band. His eyes bulged with excitement as he watched.

"Fuck me deeper!" Jackie begged. "Ohhh, Marlene, fuck me deeper! I wish your tongue was a cock! I wish it was a big, hard, cock fucking me! Ohhh, I want some cock! I need some cock! My cunt wants a hard cock fucking it! Ooooh, Marlene, hurry, hurry!"

For just a moment, she shoved her sister's face out of her cunt, twisting it for her son's eyes, letting him see how wet and hot and hairy it was, then she jerked Marlene's mouth back onto it, twisting with a greater frenzy at her sister's sucking mouth and darting tongue.

"Ohhh, I'm getting close, Marlene!" she cried out. "I'm getting ready to come! Suck me, lick me! Ohhh, my cunt! I'm about to come, you fucking crazy bitch!"

Marlene rammed her tongue in and out of her sister's cunt, holding as tightly as she could to her bouncing, naked ass with her hands. She moaned along with Jackie, feeling her own clit bulging, tingling. The crotch of her skimpy panties were soaked with her own juices, and her tits felt as if they would burst from her bra.

Jackie cried out with ecstasy, her hands now smashing into her naked tits, squeezing at them, pulling and twisting her pink nipples. She strained her cunt into her sister's face, a scream of mindless ecstasy starting in her throat. When she felt as if she couldn't stand it any longer, she grabbed Marlene's head again, smothering her sister's face into her hairy, juicy cunt.
