"Oh, yes! That feels good!" she said. "I need something in there!"

When he pulled his finger put, she rolled over onto her back.

"Fuck me, honey!" she said.

Spreading her legs, she pulled her knees back against her chest to raise up her crotch. Martha gazed down at her sister's hairy cunt. The pink meat of Claire's pussy glistened with juice.

Martha shivered as Frank leaned over to run his tongue up and down the oozing slit of his wife's cunt Claire groaned. "Eat me. Eat my pussy!"

Martha trembled as she watched the perverted act. She shuddered at the idea that a man would want to put his mouth on a woman's cunt, but she knew that people did such things.

How naive she was! She'd been engaged at eighteen and had given her virginity to her fiancee. Not long after taking her cherry, he had jilted her and married someone else.

The shock of what happened had never left her. She had kept men at a distance, satisfying herself with masturbation whenever she felt the need. She knew there were all sorts of things men and women did together, and in her fantasia she sometimes thought about them. But thinking about things was one thing and seeing them was something else.

Watching Frank in the act of licking her sister's pussy made her shudder with lust. Frank was on his knees now, shuffling forward with his cock pointed at Claire's cunt.

"Put it in!" Claire hissed. "Fuck me!"

Fisting his cock shaft, Frank rubbed his cock head around in the meat of Claire's cunt until he found her hole.

"Oh, God! That feels good!" Claire moaned.

A moment later his long thick cock sank to the hilt in her fuck hole.

"Oh, Jesus!" Claire cried out.

He began fucking her, his hands pushing her knees back to her tits, his hips swinging, his crotch pumping as he pistoned his cock in and out of her juicy cunt.
