Holding up one huge tit, Marie dropped her head and sucked the fat, crinkled nipple into her mouth. Furiously she sucked it, like a baby nursing for milk. Kelly squealed and twisted on the bed, rubbing her thighs together in a desperate effort to stop the wetness seething through her cunt.

"Now you're gonna suck me!" Acting as self-assured as any man, Marie grabbed her sister's ankles and pulled her down the bed. Then she straddled her face, planting her knees on the mattress to either side of her ears. "Suck it, Kelly! Suck it just like I sucked you! Suck off my fucking cunt!"

Kelly blushed at the sound of her sister's terse obscenities. Looking up, she found herself staring directly at the dark fur-fringed petals of Marie's cunt. The pink pussy gash was glistening with fuck oil, drooling from the depths of her cunt. Kelly could already smell Marie's pussy juices, and they were different from her own… thicker, more musky.

"Suck it, you bitch!" Marie cried. Grabbing Kelly's head, she dropped her ass and ground her mushy pussy onto her sister's mouth. "I'm so fucking hot! Suck the cream out of my cunt!"

Automatically Kelly slid her hands up Marie's sleek thighs, cupping the rounded cheeks of her tight ass. Kelly's mouth was covered by her sister's pussy, and she realized with some surprise how much the taste and feel of Marie's little cunt turned her on.

Kelly pushed out her tongue. Marie whined girlishly as it stabbed into her pouting pussy hole, probing the inner pinkness of her cunt tunnel. "Lick it!" Marie hissed. Reaching down, she spread her pussy lips, making her swollen clit pop out. "You know where, Kelly! Lick my cunt!"
