Jeff trapped the stiff little nipple between his teeth and lightly bit down. He flicked his tongue over the eraser-like nipple, eliciting moans of delight from his mother's throat. Matching her grinding motions, he flexed his ass muscles, sending his cock roving around more forcefully inside her drenched cunt.
As her body started to undulate and rock, Jeff could feel the constrictions of the tightest parts of her pussy clutch and stroke his prickshaft like a well-trained fist. His cock felt like a firehose plugged up at the nozzle, swelling, ready to burst. He agonized in extreme ecstasy with each pump of her tight pussy over the bulging parts of his cockshaft.
Moans of increasing pleasure rippled from his mouth. His ass continued to rise and fall in short, slow movements as it tightened and relaxed, his cock inflating and pulsing and moving around inside her eager pussy. On the upstrokes, he pressed and gnashed his pelvis around hers, stimulating her super-charged clit to greater orgasmic release.
Dianne seemed to be losing control of all her senses, except those in her cunt and tits. Her mind reeled and her blood boiled with the impending release of another nerve-wracking orgasm. She grew more powerless, more willing to relinquish complete control of her body to Jeff. The more forcefully and rapidly he fucked his cock into her, the more she wanted him to ravage her completely and mercilessly, leaving her weak and sated in the wake of another orgasm.
Her muscles relaxed and grew limp. Her body began lowering closer to his. Her knees trembled and her legs and arms went weak as she ground and thrust her cunt less and less vigorously on his cock.
Jeff didn't disappoint her. He could feel her body succumbing to the need to be fucked powerfully. Sharp sighs escaped her throat as he fucked her cunt all the faster, all the harder.
A piercing wail of desperation escaped from Dianne's throat when Jeff pulled his cock from her churning cunt. He placed her face-down beside him, then crawled around back and fucked his throbbing cock up her cunt from behind.
Dianne was powerless and she loved it. Sharp grunts and yelps filled the air with each thrust of his bludgeoning cock into her. She lay with her cheek on a pillow, spit drooling out of her open, half-twisted mouth as her son hammered her pussy.
"Unh God, Jeff," she cried, her words obliterated by the pillow. "More, more, more! I love it! Fuck me as hard as you can! I can't get enough of your cock! I've never come so much in my life!"
With infinite youthful vigor, Jeff fucked his cock into her insatiable pussy. His biceps bulged impressively as he clutched his mother's hips and yanked her ass back to meet every one of his forceful thrusts into her. His jaw hung open and his chest heaved rapidly.
"Oh, God, Ma!" he panted. "Oh God, oh God, oh God!"
Tears formed in his eyes as he felt the familiar tingling sensation in his balls that preceded every orgasm. His knuckles whitened as he dug his fingers into her hips and slapped her ass back all the more forcefully. His body convulsed as massive spurts of his cum fired into the flooded chamber of her pussy.
Dianne managed to slip a weak arm under her body, her hand just barely extending to her cunt. With rapid-fire speed and excellent precision, her fingertip flickered over her exposed, quivering clit, and she exploded.
Unintelligible words and grunts and shrieks filled the room as they came simultaneously.
Almost as rapidly as it began, it ended. Except for their uncontrollable rapid breathing, they were motionless. Jeff collapsed on top of his mother, forcing her to the bed.
"Oh God, Jeffy," Dianne said. "That was magnificent. I've never been fucked so thoroughly in my life. How was it for you? Was it as good as those little girls you occasionally get to swing on your cock?"
Jeff sputtered as he laughed. "Are you kidding? A hundred times better. A thousand times better!"
"Good. But believe me, it'll get better yet. All we need to do is practice."
And over the next several months, Dianne seized every opportunity she could to fuck him. Whenever her husband Ron, Tess and her other son, Andy, were gone, she and Jeff had another opportunity to practice fucking, as she put it.
"I don't want you to disappoint your little fuck partners," she would say. "Besides, practice is its own reward, and you can never get too much."
They fucked in just about every part of the house and in every position possible. The days, and some of the nights, were spent in wild fuck sessions.
Jeff suddenly had his hands full trying to fit both his sister and his mother into his busy fucking schedule. But he didn't complain.
And neither did Dianne. Now she was getting more than her share, for she and Ron were still fucking regularly.
Then one day everything changed. Jeff was fucking his mother from behind again, a position that both of them preferred. They were in the fenced-in back yard. Jeff had been swimming in the pool when Dianne came home, and she had coaxed him out of the water and between her legs.
Then, with the sun beating down on them warmly, drying the sweat on their bare backs as Jeff fucked his cock into her from behind, they were startled to hear the patio door open. Their hearts thudded in panic as Tess stepped onto the patio in her bikini bathing suit.
CHAPTER FIVE
Dianne and Jeff froze, remaining absolutely still – unable to speak, to disengage themselves, or anything else – except to wonder, in fear and panic, what might happen next.
The tension was broken when a broad lusty smile spread across Tess' bright pretty face.
"Well," she said. "You didn't tell me we were having a party." As she stepped out onto the patio, she reached behind her and undid her scant bikini top. She dangled the strap across the flagstones as she approached her mother and brother, then let the top fall into a tiny brightly colored puddle near them.
They looked up along the smooth tanned lines of her shapely legs. Up past the pink triangle of shiny material covering the mound of her cunt. Up past the curves of her hips and narrow flanks. Up to the gorgeous set of full melon-like globes of her exposed tits. And up further to the sensuous smile pasted on her pretty face.
Slipping two fingers under the elastic of her bikini bottom, she wriggled her ass, the polyester material slithering over her hips and down her legs. She jutted her hips forward slightly, exposing the delicate fluff of her yellow cunthair.
"Joiners?" she asked, her voice syrupy with sexual heat. "Or is this a private party?"
Dianne cleared her throat and tried to pull her ass forward, yanking her pussy off Jeff's cock. But his fingertips were buried in the flesh of her hips. She reached up and nervously flung her sweaty bangs off her forehead.
"This is none of your business! Just get out of here!" Dianne's voice cracked, her body shaking suddenly, her eyes scanning the patio in desperate search of something to cover her nakedness.
"Whose business is it, then?" Tess asked, swiveling her hips. She had placed her hands on her tits and rotated them into her chest, undulating her body as though her tits itched and ached deep inside where she couldn't scratch. "Daddy's?"
She leered at her mother and ran her tongue sensuously over her upper lip.
"Don't you dare," Dianne said. "Don't you dare say a word about this to anyone, or you'll live to regret it!"
"Oh, I won't say anything," Tess said in a lilting voice. "As long as you let me join the party."
Dianne felt Jeff's cock twitch inside her pussy. My God, she thought, it must have grown to twice its size just at the mention of Tess making it a threesome. She tried to laugh.
She looked up again at Tess' beautiful features, her shimmering eyes, her long yellow hair, her tits cupped under her hands – and the delightful patch of bright-gold fluff just above her pussy. Her heart suddenly leapt into her throat.
