Sister's Keeper - Part 3
by Damon

Julie continued to punish Kathleen, her strong hands locked underneath the other brunette's chin and pulling back hard, eliciting an anguished moan from Kathleen, who felt that her back would break any minute now.

Suddenly, thankfully, the pressure ceased and the fingers pulled away from Kath's jaw; but her ordeal was just beginning as Kathleen then felt Julie's hands sliding underneath and past her armpits. She then felt Julie's fingers intertwine behind the back of her neck, whereby Julie pressed down hard even as she dragged Kathleen to her feet and held her both upright and helpless in a full-nelson wrestling hold.

"F-cking bitch!" cried Kathleen, arms flailing uselessly above her head as Julie kept pressing down hard on the back of Kathleen's neck with her interlocked hands, the two warring women virtually the same height.

"No, it's f-ck YOU, bitch!" shot back Julie as she held her prey aloft, Jules' bare feet shifting on the carpet as Kathleen tried to twist free from her tormentor's grasp. "Now Jenn and I are going to torture your fat ass, just the two of us!"

Jules looked over and smiled knowingly at her sister, Jennifer, who now was upright and methodically sashaying her way towards the two battling naked brunettes. Kath pressed her head back against Julie's hands, trying to straighten herself up, trying to ready herself for the impending assault she knew was coming just as Jennifer reached out with both hands ...

... and latched them onto Kathleen's bare breasts to once more began squeezing them savagely, fingers sinking into the soft flesh, anchored there by short but sharp nails. Kathleen screamed out loud at this new agony as Jennifer squeezed even harder, her clear-colored claws stabbing into her enemy’s alabaster skin just as ferociously.

Jules smiled sinisterly as she saw the determination scrawled across her sister's face, saw Jenn’s eyes widen and her two rows of perfect teeth clenched together in both hatred and effort. Jules then looked down over Kath's right shoulder to see her sister's strong hands absolutely crushing Kath's perfect breasts, and Jules grinned even wider, pleased that she could help her sister make her mortal adversary suffer.

Kathleen wailed aloud once more as the three women twisted to and fro on the floor, like a three-car train trying to throw a track, Jules holding Kathleen at bay, Kathleen struggling to escape, and Jennifer squeezing the living shit out of Kathleen's ample chest.

"Hurts like hell, doesn't it, whore?" chided Jennifer, a small wicked smile creasing her lips as she reveled in Kathleen’s agony. "Hurts having your tits squeezed while you squeal like some kind of sow?"

Jennifer then increased the pressure with both hands, Kathleen screaming even worse now, even as Jules joined in her sister's mocking session.
"Crush ‘em, sis!" she snarled. "Crush those f-cking tits! Crush ‘em like silly putty!"

Tears threatened to stream from Kathleen's beautiful brown eyes from the unbelievable pain, and she stumbled slightly in the mutual grasps of her twin tormentors as she struggled between the two smiling sisters, Jules on her back and continuing to trap her, Jennifer pressing in closer from the front and absolutely wrenching Kath's breasts from side to side with both hands.

But by coming closer, lost in her desire to further punish her long-time foe, Jennifer had unwittingly given Kathleen an opportunity to counterattack, one that Kathleen took full advantage of as she suddenly rammed her right knee upwards into Jenn's unprotected crotch with an audible crack of bone-on-bone. Jennifer yelped from the sudden, unexpected blow, and gasped for air as she released Kathleen's breasts to reach down between her own legs and try to assuage this new agony, the redhead nearly falling over from the pain.

Julie stared incredulously as she watched her sister recoil, and she softened her own two-handed hold just long enough for Kathleen to force her head back violently and smash the back of her skull square into Julie's face. Julie was stunned even more than Jennifer had been, and her grip was all but gone, enabling Kathleen to reach up behind her new foe with both hands and latch them onto the back of Julie's swimming head.

Kathleen then bent over forward violently, as hard and as quickly as she could. She pulled Jules along with her, sending the other naked brunette sailing ass over teakettle where she crashed into her suffering sister, their skulls colliding with a dull thud as the two siblings were knocked to the floor in a scrunched–up tangle of slender arms and legs.

Kathleen stepped back shakily and then fell down herself, her ample ass cheeks hitting the carpet hard as she failed to control her freefall descent. The pain was nothing new to her - she expected and even welcomed it, even as she massaged her own sore breasts tenderly, the skin still discolored where Jennifer's fingers had sunk in so deeply, accompanied by several random red scratches.

The brunette wiped her moist eyes with one arm and then stared hatefully at the barely-moving sisterly heap in front of her. She wished there was a baseball bat or some other such object within reach, something sufficiently hard that she could swing repeatedly and smash the very life out of her two assailants; but a cursory glance of the basement revealed no such instrument of mayhem.

No matter, thought Kathleen, as she ambled forward gingerly on her hands and knees towards her unwitting enemies. She much preferred to use her bare hands ...

Kathleen made her way over to where Jules and Jennifer still lay stunned from their momentary head-to-head collision. The sisters had no notion their mutual prey/enemy was advancing upon them until Kathleen had made it over on her hands and knees. The battered brunette battler roughly pulled her dark-haired foe off of her redheaded sister, and then wrapped her left arm around Julie's neck in a chokehold. A semi-conscious Julie suddenly gasped for air as Kathleen pulled her prey along, the attacking brunette then sliding her long, tapering legs about either side of Jenn's slender neck before locking the ankles of her bare feet together and squeezing the redhead in a classic neck scissors.

Jennifer cried out hoarsely at the pain that now collected in her throat, and began trying to pry Kathleen's legs from about her neck even as her sister tried to pull free of Kathleen's constricting arm; but the two siblings were stuck, as Kathleen began to pay her two adversaries back for the injuries they had inflicted upon her earlier in their encounter - the crushing two-handed chokes about her neck, and the brutal squeezing of her soft breasts.

Kathleen wrenched her arm tighter about Jules' neck, squeezed her legs tighter about Jenn's windpipe - and then Kathleen threw back her head and laughed derisively as the sisters struggled futilely to break free from her python-like grasps, their anguished moans mixing with their tormentor’s expression of sheer joy.

Their all-nude girls-only threesome struggle had become a one-on-two situation - and the one was now winning handily over the two.

Kathleen continued to grind Jules’ head and neck in her left arm while pressing her interlocked legs tighter and tighter about Jenn’s neck. Both sisters cried out in anguish as they suffered in their one-time victim’s dual grasps, but neither sibling could break free from the brunette’s breath-squeezing holds. Jennifer beat at Kathleen’s legs with her balled-up fists to no avail, while Jules tried to push free of the arm encircling her neck only to feel her oppressor tighten her grip, constricting her throat even tighter and cutting off her air supply while doing the same to her sister, as Kathleen locked the ankles of her bare feet together even tighter, the left one hooked about the right.

“Having fun yet, ladies?” she chided, wanting to take full advantage of the situation. She didn’t receive any reply from either of her choking victims, but then, she didn’t expect one, either.
Kathleen reveled in Jules’ tortured coughs first, the entrapped brunette’s face beginning to turn redder than her sister’s hair as Jennifer arched her back just a few feet away and tried to bridge herself free of her mortal enemy’s lethal scissors, only to fail once more and continue coughing her lungs out, also to Kath's delight.

Kathleen grinned as big as the moon, fully assured that she had her enemies right where she wanted them ...

.. and then heady thoughts of a dual, all-at-once victory were pushed away as a new agony collected in her chest and squeezed it - or rather, squeezed her exposed breasts, as Jules reached around from behind and sank her fingers into Kath’s soft, yielding mounds.

Kathleen cried out and released Julie's head as she fumbled at Jules' wrists, trying to pry those crushing hands from her already tortured breasts, while Julie swung her upper body behind Kathleen’s and then dug her chin into Kathleen's left collarbone from behind for leverage, coughs still emanating from the attacking brunette as a new fury raged in her eyes as she began to repay Kathleen for her cruelty.

Several feet away Jenn had managed to get her hands and arms between Kathleen's calves and then pushed herself free of Kathleen's long, choking legs as the preoccupied brunette softened her scissors just long enough for her long-time foe to escape. Jennifer rubbed her raw throat with one hand and coughed, and smiled as she saw her sister punishing their mutual adversary once more, Kathleen crying out and gripping Jules' wrists futilely as her attacker's fingers made deep, ugly depressions in Kathleen's ample breasts.

"Suffer, slut!" snarled Jules through clenched white teeth as she worked her steely fingers deeper into Kathleen's yielding white mounds, increasing her victim's wailing.

Jennifer then snarled herself before reaching forward with both hands towards the battling brunettes, her left hand pinching Kathleen's nostrils closed just as the redhead plastered her right palm hard over Kathleen's mouth.

"Smother, you f-cking bitch!" snarled Jennifer hatefully.

Kathleen's banshee-like wailing suddenly ceased as her breathing passages were sealed off, and her eyes grew wide as the entrapped brunette began to slowly suffocate, breasts again aching terribly. She was once more caught between the two sisters, who had both the ability and the desire to finish her off, once and for all.
