She became eager to have her son at her window at night, looking in at her as she undressed. Jackie began to undress in ways that she knew would excite her son, slowly and with plenty of suggestive movements. Now, with her son peeking at her and Marlene, Jackie hoped her son was enjoying it as much as she was.

Marlene pressed the tip of her finger against her sister's swollen clit, causing Jackie's hips to lurch.

"Ohhh, you almost made me come then!" Jackie moaned, glancing at the window, seeing her son's bright eyes just above the sill.

"Not until I can get my mouth on your sweet, juicy cunt, Jackie," Marlene laughed, a low, husky sound. "I want to taste how hot you are, lick up those delicious pussy-juices."

"Then you better start licking," Jackie whimpered, twisting her ass from side to side. "You know what your fingers do to me."

Jackie ran her hands downward, her fingers moving through the thick curls of her blonde pussy-hair. She slitted her eyes and glanced at the window as she parted the puffy lips of her cunt. She saw her son's eyes grow wide, and shifted her ass toward the window a little more, wanting her son to get a good look at her pink, juicy cunt. Jackie lifted her ass up, grinding as her sister fondled her bunching asscheeks.

"Eat me now, Marlene," she pleaded softly, her eyes gazing at her son's face. "Stick your tongue in me and lick my pussy! You've made me so fucking hot, I could come right now!"

Marlene moved bet middle finger into her sister's cunt, pushing it in to her knuckle. Jackie gasped with pleasure and began to fuck back and forth on Marlene's finger, mewling as the hairy lips of her cunt spasmed, trying to take the finger deeper.
