Karen was panting, her eyes smoldering as she watched Sarah's hairy, soft, hot and wet cunt thrusting up and down. She could see the pink lips spread about her fingers, feel the softness of the inside, the steamy wetness. Her own cunt was on fire now, burning as hotly as her sister's, and she rushed her hand into her panties, finger fucking herself furiously.

"Pump, Sarah, pump!" she moaned.

"I am!" Karen sobbed, her fingers now on the lips of her stretched cunt, pulling it wider. "I am pumping!"

With her head twisting about, her eyes closed, Sarah gasped and cried out with ecstasy, ecstasy that was making her mind spin wilder and wilder. Her hips churned wantonly, the cheeks of her ass bunching.

"Karen! Ohhhhhhhh, Karen, it's going to happen!" she shrieked. "I'm about to come, Karen! Ohhhh, hard, please! Deeper… fuck me deeper! I'm about to come and I want to be fucked hard and deep!"

Screaming out her rapture, Sarah jerked upward, her arms wrapping around the back of them. She humped her ass up and down frantically while her sister once more rammed her fingers into her fiery cunt. The orgasm burned and swelled, and with a shout, Sarah came. The convulsions were strong, as strong as they had been when she fucked her son. Her ass lurched up, grinding as she screamed in ecstasy.

Karen felt Sarah's cunt grabbing and squeezing her fingers, and with a low moan of satisfaction, her own cunt contracted about her darting finger, but her orgasm was not as strong as Sarah's. As the orgasm wound down, Sarah's ass slumped, her long legs straight out, spread open. Karen pulled her drenched fingers out of her sister's bushy cunt, lifting her hand from her panties.

She was standing up when Jimmy came in the front door.

Jimmy stopped in his tracks, staring at his mother's lewd exposure, seeing her juicy cunt gleaming wetly.
