"Marlene, eat me!" she sobbed. "Eat me now!"

Marlene leaned down, sliding her tongue along Jackie's inner thigh, curling her fingers into the tight cheeks of her sister's ass, lifting her cunt higher. Jackie gasped at the wet heat of her sister's tongue, her eyes unfocused with desire. She could no longer see the face of her young son except as a blur. She lifted her cunt higher as her sister's long, wet tongue swirled along her flesh, moving with agonizing slowness toward her cunt.

Jackie's head was propped on a pillow, her chin tucked down. She could see her sister's face clearly, see her long tongue swishing along her thigh. Her pussy twitched and burned, sinking inward with pulsations of readiness. Her vision cleared for a moment, and she saw her son had lifted his head higher at the window sill, his eyes blazing as he, too, watched Marlene's tongue getting closer to Jackie's cunt.

"Suck my cunt!" Jackie screamed. She grabbed her sister's head and jerked it down. "Tongue fuck me now!"

Marlene gurgled as her open mouth made contact with Jackie's fiery cunt, and her tongue shot into it. Jackie squealed and rammed her pussy into her sister's mouth, closing her hot thighs about Marlene's face, squeezing them, then flinging them wide-open again.

She strained her burning pussy into Marlene's face, humping up and down, fucking on her darting tongue. She groaned and whimpered, thrashing about with increasing ecstasy.

Marlene clung to Jackie's dancing, naked ass with her hands, letting Jackie smear her wet cunt into her face. She drew her knees wider her body and shoved her ass into the air. She made wet sounds as her tongue lapped and dipped into Jackie's juicy cunt.

Jackie sobbed loudly, grinding her cunt at Marlene's mouth hard, trying to see her son at the window, but her excitement was so intense, she couldn't even see a blur now. She hoped her son could see everything, see Marlene's tongue darting into her cunt, see her naked tits, with those long, pink nipples throbbing so hard, see how Marlene clung to her bouncing ass. She hoped her son could see Marlene's ass, waving about in the air, even if Marlene did have those skimpy panties on. She hoped her son could see her sister's cunt through the panties, and she hoped Timmy's cock was very hard his balls swollen.
