Auntie's incest urge

CHAPTER TEN

Claire Burton was smart enough to realize that something was going on in the house, something unusual and known to everyone except herself.

Her husband and children and sister were all acting a little strangely. She caught mysterious glances between them. It was as if they had a secret they were deliberately keeping from her.

The answer to the riddle came one day in the attic. They had more or less decided to sell the old house, and Claire was up in the attic making a last inspection of things they might want to take with than when they left. They had to get rid of all the old junk up there.

She was rummaging through an old trunk when she heard Ricky's voice. She was startled at first, because she hadn't heard anyone come into the attic. Then she realized he wasn't in the attic at all. His voice had come from down below. She realized the sound of his voice had come up through one of the grates that connected the attic with the bedrooms.

Then she beard his voice again, and this time she realized there was something strange about it.

He sounded almost in pain, as though he were groaning.

Her eyes quickly ran over the floor of the attic until she located the place where the sound was coming from. From the position of the grate, she realized it wasn't Ricky's room at all. She pushed aside some aid cartons to get at the opening, and when she peered down she found herself looking into Martha's room.

The grate was directly over Martha's bed. Ricky was inched out on the bed on his back. Martha was kneeling between his legs sucking his cock.

Claire was paralyzed with shock. At first she didn't believe what she was seeing. Then she realized the scene below was very real. That was her son on the bed down there, and that was her sister with her son's cock in her mouth.

Quivering, her heart pounding as she settled in at her ringside seat. Claire gazed down at the couple on the bed and bit her lip to keep herself from gasping out loud.

Martha was in the process of giving Ricky a slow blow-job. She seemed in no hurry at all Claire watched as her sister lapped and licked the boy's spongy cock head. She hadn't seen Ricky's prick in years, and she was surprised at the size of it.

Martha slurped over the bloated knob as though it were an ice cream cone. She held the boy's balls her fingers, probing his nuts, and then her fist closed around his cock shaft to pump his meat while she sucked on his cock head. At intervals she would pull back and flutter the tip of her tongue at his piss hole.

She's an expert, Claire thought. My little sister gives head like an expert cock sucker!

She watched with amazement as Martha lifted the boy's balls and slowly drilled a finger into his asshole. Licking and sucking on Ricky's nuts, Martha slowly fucked her finger in and out of the boy's shitter.

Then she pulled her face off his cock and continued pumping his cock shaft slowly, to the same rhythm as the finger fucking the boy's ass.

Finally pulling her finger out of his asshole, the brunette lowered her face, nuzzled his balls, and pushed his legs back to his chest to raise his crotch up in the air.

Her eyes wide with amazement, Claire watched as Martha fluttered her tongue from Ricky's balls down to his asshole. Zeroing in on the puckered ring of the boy's shitter, Martha began lapping and tickling it with her tongue.

Claire shuddered with disbelief. Was this actually her prudish sister? This was an unknown Martha, a Martha whose existence she had never suspected. Her sister was down there tonguing the ass of her son!

Now Martha pulled her mouth any from Ricky's ass and moved back to his cock head. She sucked and slurped on his knob again, one hand holding his cock shaft and the other hand cradling his balls.

She could teach me a trick or two! Claire thought. She wondered how innocent Ricky was. Was this the first time the two of them were together?

He was so much like his father. Young as he was, he had the cock and balls of a full-grown man. She felt strange looking at him. A feeling of incestuous lust washed over her and made her pussy quiver.

Martha finally pulled her mouth and hands away from Ricky's cock.

"Enough for now, honey," she said. "You can lick my pussy awhile."

She rolled over and stretched out on her back. Ricky scrambled to his knees between her legs and ran his hands along the insides of her thighs to her cunt. Martha pulled her knees back to her chest and opened her legs to expose her hairy crotch.

"Make it last!" Martha said. "Just take your time."

It was now obvious to Claire that this was not the first time for them. They were too much at ease with each other. She wondered how long it had been going on!

How ironic it was that her sister and her son had been having an affair and she had never suspected it! At least he's got a good teacher! Claire giggled silently.

The boy was opening Martha's cunt now. He pulled apart the hairy pussy lips and ran his forefingers along each side of Martha's stiff pink clit.

Claire gazed down with fascination at her sister's open cunt. Although they were sisters, in many ways they were different. Martha was a brunette. Her dark hairy ass was so unlike Claire's blonde pussy!

"Eat me!" Martha hissed at Ricky. "Suck my pussy now!"

The boy swooped down on Martha's open oozing cunt. He mashed his face into her wet crotch. Claire could hear the squishing of her sister's cunt juice on her son's nose and cheeks. She watched with amazement at the expert way Ricky massaged Martha's clit with the tip of his nose.

When the boy pulled his face away from Martha's crotch, his lips were glistening with Martha's juice.

"Let's do sixty-nine!" he grinned.

A moment later he was straddled over Martha with his face over her crotch and his cock hanging over her mouth. Claire watched as Martha sucked the boy's cock and then released it to lick and suck on his dangling balls.

Ricky slurped up Martha's cunt juice and fucked his finger in and out of her cunt hole. Aunt and nephew slobbered over each other's crotches with loud sucking noises.

Martha's hands roamed over Ricky's ass. She moved her fingers into the crack of his ass, teased the rim of his ass hole and finally drilled a finger deep inside his shitter. The boy grunted and began sucking her cunt more forcefully.

Claire's pussy was on fire with lust as she watched the antics of the couple below. With a soft moan, she pushed three fingers inside her sopping cunt. Another finger tickled her asshole, and in a moment she had fingers in her ass and cunt, pumping both holes with her hand for all she was worth.

She was able to strum her clit with her thumb at the same time, and the total stimulation of her crotch soon had her crazy.

"Oh, God, I'm coming!" Martha wailed down on the bed.

Ricky's face was working in her crotch like a machine.

"Suck me!" Martha groaned. "Suck me out!"

She thrashed under the boy, her finger working his asshole, his balls slapping back and forth on her nose. In the midst of her orgasm, she greedily gobbled up the boy's cock and frantically pumped him until he shot his load down her throat. When Ricky finally rolled off Martha's body, his balls were obviously drained.

Up in the attic, Claire was finishing one come and beginning another. She was in a daze. The excitement of watching her sister and son fucking on the bed directly under her eyes was almost too much to bear.

She saw Ricky get up and leave the room. She watched as Martha lay back on the bed idly fingering her pussy. Although her rhythm had slowed, Claire continued strumming her clit, her eyes fixed on Martha, who was now doing the same thing.

Claire came just as a knock sounded on the door below. She gasped when a moment later Frank walked into the room. He chuckled, his eyes glittering, when he saw Martha lying on the bed playing with her pussy.

"Well, you look ready enough," Frank said.

Martha groaned. "You shouldn't do this. It's too dangerous. I think I'd die if Claire ever found out."

"Don't worry about Claire," Frank said. "She doesn't seem to be in the house."

He started undressing, his eyes fixed on Martha's hand as it continued massaging her hairy open cunt.

Trembling with anticipation, her hand once more rubbing her cunt, Claire watched as Martha rose up to sit on the edge of the bed. Frank stood in front of her, his cock swaying under her nose, his hands caressing Martha's hair.

Opening her mouth, Martha gluttonously engulfed the knob of his cock. She began a vigorous sucking. Her hands moved around to clutch his ass cheeks. Her head bobbed up and down as the ring of her lips slid back and forth over his cock shaft.

"Oh, yeah!" Frank groaned. "That's good!"

Holding her ears, he gradually assumed control of the movements. Martha held her head still as he began fucking her mouth with his pistoning cock.

Claire watched the face fucking with a combination of shock and lust. She was turned on by the lewd sight of her husband pumping his cock in and out of her sister's hungry mouth.

She wondered how many other women Frank had fucked during their marriage. She wondered how long he and Martha had been having an affair. How strange it was! It was hard to believe that her husband was actually down there face-fucking her sister.

There was no way to deny that it turned her on. Watching Martha take Frank's cock in and out of her throat was the most erotic thing Claire had ever seen. Claire was sure they had done this before.

Once again she was shocked at how expert Martha was at cock sucking. First Ricky and now Frank. Martha had certainly captured the men in his family! Whatever resentment Claire had was overshadowed by her lust.

Frank was reaching down to hold Martha's tits and groaning, "Suck it, baby God, what a mouth! You like it when I fuck your face like this, don't you? Christ, it's good!"

Claire stifled a groan as she started coming. She worked her cunt furiously with her hand, her hips pumping as spasm after spasm convulsed her pussy. She thought she would come at the same time as Frank, but he surprised her by pulling his cock out of Martha's mouth.

"I'll finish in your ass, baby!" he said.

Claire jerked her way though an orgasm as she stared transfixed at the scene below. Martha was now greasing up Frank's cock with some cold-cream. The brunette put the jar away and turned over to kneel on the bed with her head down and her ass in the air facing Frank.

"Gorgeous ass!" Frank chuckled. His hands roamed over Martha's ass cheeks, his fingers dipping into the dark hairy crack. Positioning his cock head on the rim of her asshole, he pushed forward and sank his prick to the hilt inside her shitter.

A long wail came out of Martha's throat.

"Fuck me!" she groaned. "Oh, God, I'm coming! Fuck me!"

Frank began pumping his cock in and out of Martha's shit hole. Claire trembled and groaned and shook as she watched the frenzied scene below. It wasn't long before a grunt rumbled out of Frank's chest as he started to shoot his load in Martha's ass.

Her fingers working frantically in her cunt, this time Claire came along with her husband. Slumping down on the floor beside the grate, Claire was only vaguely aware of Frank leaving Martha's room.

Minutes passed. As Claire recovered her senses, she realized someone was knocking on Martha's door again. She groaned when a moment later Josie walked into the room. Oh, God, no, not Josie! She thought.

She gazed down at her sister and her daughter. They were whispering to each other, their hands on each other's tits, as Josie stripped her clothes off.

Soon they were both naked on the bed with their fingers fluttering over each other's pussies. Claire was mesmerized.

"I'd rather play with a cock," Josie giggled. "But sometimes this is just as good."

Oh. Jesus! Claire thought. Thank God, she's not a lesbian.

Lesbian or not, Josie had an obvious liking for pussy. Claire watched the girl climb between Martha's thighs and lower her face to Martha's sopping crotch.

"Oh, Jesus! This is a wet cunt," Josie laughed. "Who's been here?"

"Never mind that," Martha chuckled. "Just get to work."

Claire shuddered as she watched her daughter begin slurping at Martha's jism-drenched cunt. She had a feeling Josie knew exactly what she was doing. Damn Martha! She was sure a lusty bitch! She had been deceiving Claire all these years.

When Josie raised her mouth from Martha's crotch, her face was covered with Martha's cunt juice.

"Let's do sixty-nine," Josie said.

This isn't the first time, Claire thought. They've done this before. Oh, God, what a fool I've been!

Josie was now straddling Martha, her face hovering over Martha's crotch and her cunt swaying over Martha's mouth. A moment later Josie dropped her crotch down onto Martha's face and Martha began sucking and nuzzling at the teenager's blonde pussy.

Above them, her eyes wide as she continued peering through the grate, Claire frigged her cunt in a frenzy. The sight of her sister and her daughter sucking each other's cunts drove her wild.

She was using two hands to frig herself now. She had one under her ass with a finger plugging her asshole. The other hand massaged her pussy with three fingers pumping in and out of her cunt hole.

Josie's ass and Martha's face were directly below her. She found herself staring at her daughter's tight-looking brown asshole. She could see Martha's lips and tongue working over Josie's cunt.

At intervals one or the other would pull her face away from the wet crotch she'd been sucking and cry out her pleasure. Martha slurped like an animal on the teenager's dripping pussy. Josie bounced her cunt up and down on her aunt's face.

Claire couldn't help being jealous. She was jealous of Josie. How lovely it would be to mash her cunt on Martha's face!

Josie was going wild now. She wailed and moaned as Martha drilled a finger into the teenager's ass. Once again Claire was amazed at how expert Martha was.

They were coming now. Josie shuddered through what looked like a mind-blowing orgasm, her crotch pumping up and down on Martha's upturned face. A moment later Martha began bucking her hips, fucking her cunt at Josie's mouth, her body shaking as she came.

When they rolled apart, Martha leaned over and kissed Josie's cheek.

"Do you like this better than fucking Ricky?" Martha asked.

Josie smiled. "Nothing is better than fucking Ricky," she said.

Above them, Claire gasped. She understood now that brother and sister were fucking. Her heart pounding, she moved away from the grate and quietly left the attic.
