Stiffening four of her fingers together, Karen pushed them into her sister's cunt, bringing a squeal of ecstasy from Sarah. She began to fuck her fingers in and out, making wet sounds, the fingers of her other hand rubbing and agitating Sarah's intensely inflamed cunt.

"Ohhhh, Karen, Karen!" Sarah wailed, churning her hips up and down wantonly, twisting and wiggling, squeezing at her covered tits hard, making them tingle with a sort of pleasure and pain. "Ahhhh, yes, Karen!"

Karen's eyes glowed brightly as she watched Sarah's naked hips fly up and down, grinding on her fingers. She stabbed furiously, breathing hotly against one of Sarah's creamy thighs. The fresh, sweet scent of Sarah's juicy cunt filled her nostrils and she inhaled it greedily. She saw the juices seeping past her buried fingers, smearing the humping cheeks of Sarah's tight ass.

"Harder!" Karen cried out. "Ohhhh, please, harder… faster… deeper! Ahhhh, more, Karen… more!"

Karen really didn't have to run her fingers back and forth. Sarah was riding them with her cunt furiously, sliding her hairy, tight cunt back and forth, almost to her palm. The wet sounds excited Karen, and her own cunt began to bubble with more wetness than before. She was on her knees between the spreading legs of her sister, and she pulled her hand from Sarah's cunt and slipped it under her own skirt, rubbing at the tight crotch of her own panties, feeling her cunt burn through the flimsy cloth.

Squishy sounds wore loud as Sarah pumped her cunt up and down on her sister's fingers. She twisted and rolled her ass about her hands digging at her tits then scooting down swiftly to her thighs where she clutched the inner softness and spread them as wide as she could.

"Ohhhhh, Karen!" she wailed. "Ahhhh, please! That's so good, Karen! Oooooh, so wonderful!"
