Ramming her crotch brutally into Marlene's month, Jackie clung to the thick hair on her sister's head, jerking her face up and down. She… flung her legs open, then closed them, squeezing Marlene's head. She rammed her cunt up and down, whipping her ass about wildly, sobbing loudly with the rapture of her sister's darting tongue.

"Fuck me, fuck me!" Jackie wailed. "Ohhh, Marlene, fuck me with your tongue! God, it's so good, so good! Suck my cunt, Marlene! Suck my pussy hard!"

Marlene moaned between Jackie's thighs, her hands clutching the firm flesh of her sister's bouncing ass, digging into her ass cheeks. Her mouth was as open as she could get it, her lips pressed about the expanse of Jackie's throbbing writ, her tongue swirling about her inflamed clit, and darting into the fiery depths wickedly. The liquid sounds she made were erotic music to Jackie's ears.

Jackie's cunt burned and clutched at Marlene's tongue, trying to suck it deeper and deeper. Although Jackie was thrashing about with overwhelming heat, she was thinking of her son watching, his cock being very hard, pressing at his pajamas, maybe dripping. She could see Timmy's cock in her mind, see his young, precious balls. She ran her tongue over her lips as she sobbed softly.

"Mmmm, so juicy!" Marlene hissed.

"Yes, I am juicy!" Jackie screamed out. "My cunt is so fucking juicy! Make me come, Marlene! Ohhh, suck my cunt and make me come! God, I'm burning up! My cunt is burning up and it's juicy and I want to come!"
