Auntie_s incest urge
CHAPTER ONE
"I want that hot little pussy!"
Martha Dawson froze in her tracks. The voice belonged to Frank Burton, her brother-in-law, but she had no idea where it was coming from.
She was in the attic of the old house she and her sister had recently inherited. The musty attic was cluttered with cartons of junk and piles of old magazines and newspapers.
It occurred to her now that there must be grates connecting the attic with the bedrooms below it. She heard Frank's voice again and she followed it until she came to a grate almost totally covered by a large carton.
She shivered as she realized the grate would give her a view into the bedroom Frank and her sister Claire were using while they all stayed in the house.
She felt guilty about spying on them, but she also felt an intense curiosity.
The language which Frank had used was shocking. Martha had always been a little jealous of Claire. Claire was married. She had a man. Martha was single and although she was pretty, her shyness had kept her away from men and forced her into a life of loneliness.
She felt a compulsion now to peer into the life of Claire and Frank, to see them in the intimate setting of their bedroom. Frank was laughing and Martha became more eager than ever.
Carefully pushing the large carton away from the grate, she knelt down and peered into the room below. She saw Claire moving into Frank's arms. They were standing near the bed, fully dressed.
Frank's hands roamed over Claire's ass as she snuggled her head against his shoulder.
Martha trembled with excitement as she watched Frank massage the full globes of Claire's ass through the material of her skirt.
Although Martha was a brunette, her sister was a blonde. Claire was a few years older. She had a lush body with big tits and a curvy ass.
Frank was close to forty. He was a muscular man with dark hair and a lusty attitude toward life.
"I'm getting juicy!" Claire said.
Martha quivered as she listened. How exciting it was to spy on their intimacy!
"Just hold still and let Daddy do the work!" Frank grunted, as his fingers began unbuttoning Claire's blouse.
He slipped the blouse off and immediately unfastened her bra. Her firm creamy tits bounced free. The long pink nipples had wide aureoles.
As Martha gazed down at the couple, she quivered, realizing she was going to see more than she bargained for! She hadn't expected them to actually do anything, but it was obvious now that, they were preparing to fuck.
Frank lowered his head to kiss the white flesh of Claire's tits. He licked her nipples and sucked them briefly into his mouth. He pulled her skirt over her hips and she leaned on his shoulder as she stepped out of it. In a moment the skirt was tossed away to be draped over a chair.
Wearing only her panties now, Claire looked deliciously sexy. With a teasing laugh, she turned her back to Frank and slowly pulled her panties don to expose the creamy white globes of her ass cheeks. Peeling off her panties, she turned to face Frank again.
Martha gazed down at Claire's blonde cunt and realized she hadn't seen her sister naked in years.
Claire was unbuttoning Frank's shirt and helping him strip his clothes off. Soon the blonde was pulling her husband's shorts down to reveal his long thick cock.
Martha bit her lip as she stared down at Frank's naked body. Claire had his throbbing cock resting on her palm. She caressed his hairy balls with her free hand.
Martha trembled at the sight of her brother-in-law's prick, at his muscular hairy thighs and belly. The white cock thrusting out of his crotch seemed huge.
Martha gasped softly now as Claire opened her mouth and engulfed Frank's cock-head. She sucked on his juicy cock with abandon, her eyes closed, her lips stretched into a ring, her hand holding Frank's balls. She slowly bobbed her head up and down, sliding her mouth back and forth over the thick shaft of his cock.
The lewdness of the act made Martha shiver with lust. She had sometimes wondered what Frank and Claire did in bed and now she was finding out! People were so different when they were alone in a bedroom!
Claire was the mother of two teenage children, but at the moment she was behaving like a wanton hussy.
Martha had always thought that sucking a man's cock was the most perverted thing in the world. Watching her sister do it filled her with a combination of repulsion and lust.
"Christ!" Frank hissed. "What a mouth!" Claire pulled her lips off his cock and giggled. She looked up at him.
"You like it, huh?"
She fisted the saliva-coated shaft of his cock and pumped it few times. Then she got to her feet and they kissed. Frank's hand groped down her body and between her legs.
Martha could see his fingers working in Claire's cunt lips. Claire began to moan and pump her pussy back and forth against her husband's hand.
"Oh, God! I'm hot!" Claire groaned. "Put your finger inside!"
Frank chuckled. "Get on the bed!"
"You don't think there's any chance of the kids barging in, do you?" Claire asked.
"They're not even in the house," Frank said. "Anyway I thought we had an agreement about that."
"I guess you're right," Claire said as she climbed onto the bed.
The blonde remained on her knees with her ass facing Frank. He lowered his head now and kissed her bare ass cheeks. Then he splayed his hands over the big globes and nuzzled his face in the crack between them.
Claire purred her approval. She groaned when his hands slipped between her thighs to massage her pussy. A mewl of delight escaped her throat when he slipped a finger deep inside her cunt hole.
"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.
Martha groaned as she gazed down at the couple on the bed. Claire's tits and ass jiggled under the impact of her husband's thrusting prick. The steady hard strokes made the blonde's body quiver.
She moaned and rolled her head from side to side on the pillow. Her thighs rocked to the rhythm of Frank's fucking. She writhed as he reamed out her steaming cunt hole.
