Sienna


Allyson

An au pair had been Marco’s idea. In hindsight, Allyson realized it was an idea that he raised on return from a trip to Sicily.  And he volunteered to find and hire one.  Red flags?  Allyson was too busy to be suspicious. The twins were six now, crazy handfuls, and her work at the firm was twelve hour days. Sex with Marco had cooled, sure, but they were thirty-two now, with frantic lives, not lust-filled twenty-two-year-olds.

Marco’s search was short.  He hired Sienna in no time at all.  She was, in fact, twenty-two.  From Sicily.  Allyson was no less busy, but now she could not afford not to be suspicious. Marco worked from home. The twins were in school until 2 pm.  And Sienna was a beautiful panther, graceful and dark, charming and saucy.

Sienna was good with the twins, Allyson had to admit, teaching them French and Italian. She was turning them into expert swimmers, too, constantly at their pool on the weekends, where she cut the water like a mink.  Was it only Allyson who noticed her gradual transition from lessons in a modest one-piece to a barely-there bikini?  Marco feigned indifference.  It was California, not Church.  Let her wear what she wants.

Allyson was not indifferent.  Every move Sienna made reminded her of wet, filthy sex.

She began to come home unannounced and randomly during school hours. Most nights, she aggressively initiated sex with Marco, on the alert for Sienna’s scent on him, for any sign that he was sexually spent, to put her scent on him.

There was no evidence of impropriety.  Her unannounced visits found Marco in his office, Sienna in her room or out at errands. Instead of her suspicions abating, however, they grew as weeks passed. They covered their tracks well, Marco and Sienna, she thought.  It ate at her.

“I hear you, you know,” Sienna said to Allyson, as they were alone in the kitchen one night, Marco reading the twins to sleep. “You and Marco, when you make love.”  Sienna had helped herself to the open bottle of wine, to Allyson’s annoyance.  She sipped her glass now, her midriff bare and pushed against the center island. Allyson’s eyes slipped to Sienna’s breasts, large and full for such a slender frame. Perfect for Marco to nest his cock between.  “I don’t say this to embarrass,” Sienna added.

“Why would I be embarrassed about fucking my husband?”  Allyson’s voice was sharp. Too much wine, she thought.  Were Sienna’s eyes on her breasts now?  She arched her back, just a little.

“When you do - fuck him - you sound . . . angry,” Sienna said.

Allyson put her glass down with a sharp clink on the marble countertop.

“You are out of line, Sienna,” she said.

“The question is, why are you angry?” Sienna said. She arched her back too. Her nipples were stiff beneath her thin half-top. Allyson found herself picturing them. Were they as dark as Sienna’s eyes?  She ignored Sienna’s question.

“I want you to wear a bra,” Allyson said.  “And not that bikini.  Because of the twins.”

Sienna smiled.  “The twins are babies,” she said.  “They don’t notice my body.  Only you notice - and Marco, of course.”  She stretched.  “You are afraid of me,” she said.  “It makes you angry.”  She came around the island.  “You think I am fucking him.  I’m not.”

“Good,” Allyson said.  She couldn’t believe this conversation; couldn’t believe this girl saw right through her.  It seemed like a silly response to make, but what else could she say?

“Not yet, I mean.” Sienna said.  She reached for Allyson’s blouse, felt its material, unbuttoned its top button.  “I haven’t given him my pussy.  Oh, I did suck his cock today, many times.  I swallow all his cum, every delicious drop.  He says you did that too - when you were young, like me, but no more.”

Allyson had no words for this.

“You fuck him with anger to try to keep him from me,” Sienna said.  “It won’t work.  If I decide to let him, he will fuck me.”  She touched Allyson’s cleavage, where her blouse was open now, and ran her fingertips over the swell of her breast.  “He cannot resist me. Rather than be angry, Allyson, why not . . . join us?”

“Get out,” Allyson said.  Her tongue felt thick.  “You’re fired.”

Sienna’s hand curved, and dipped into the cup of Allyson’s bra.  Her fingers were warm, and smooth.  She lifted the weight of Allyson’s breast a fraction, her thumb caressing her nipple.

“Don’t be afraid,” she whispered.  “I don’t want to take him away from you.  I only want to play - with both of you.”  She withdrew her hand, her fingers trailing over Allyson’s stiffening nub.  “So hard,” she said.  “Like his cock.  Is your pussy wet, Allyson?”

God, yes.  Allyson was silent, but Sienna knew.

“As the saying is,” Sienna said. “You cannot beat me.  Join me.”

“I can beat you,” Allyson said. Her voice was tense.  She wanted Sienna’s hand on her breast again, and hated that she wanted it.

Sienna shook her head.  “You are still attractive, yes,” she said.  “But you are an old hat to Marco.  He aches to have me.  You, he fucks because you are . . . convenient.  You cannot beat me in bed.  Or anywhere else.”

They both heard Marco close the door to the twins’ room.

“Think of my offer,” Sienna said, and she was gone.

Later, Allyson slowly worked Marco’s cock.  A long, tantric massage, with her hands, and breasts, and mouth.  She took Marco deep into her throat, pushing her lips to the base of his shaft.  He groaned, and pulsed, and came.  There should have been a choking flood, after all she’d done, but his well was practically dry.  You bastard, Allyson thought.  She swung her long blonde hair to the side, and made him kiss her, to taste what she had in her mouth before she swallowed it.

“Have you ever thought of a threesome?” she asked.  He said no, but his eyes contradicted the lie.

“What about with Sienna,” she said.  His eyes told her the truth, once again.  She boiled with fury.

In her room, Sienna listened, and smiled, as they fought.  Who knew what tomorrow would bring?

By the time Sienna stretched awake in her bed the next morning, sheets cool on her naked body, Marco and the twins were gone.  A text from Allyson on her phone told her this.  It also told her to be out of the house by 5 pm.

“You don’t say this to my face,” Sienna said softly, to herself.  She thumbed her phone.

I don’t think I will go.  Last night, I decide - I want to feel his big cock inside me.  You may watch, Allyson, if you like.

Sienna watched the three dots that told her a reply was coming. 

He’s taken the twins to stay at his mother’s.  He’ll be home at 6.  I’ll be home at 5.  To make sure you are gone.

“Why tell me this?” Sienna said. 

You say go but then tell me we three will be alone tonight.  Say what you want, Allyson.

Alone in her office, Allyson held her phone tightly enough that her knuckles were white.

If I find you there when I get home, I will throw you out into the street myself.

LOL!  This you cannot do.  Did you consider my offer?

OUT.  I mean it!

Allyson’s phone rang.

“Some things should be spoken,” said Sienna.  “So I tell you. Today, will enjoy your pool. I will sunbathe; topless, I think. And I will be waiting for you when you arrive home.  I will give you one more chance.  Then when Marco arrives after you, he will find us both waiting to fuck him, or he will find me waiting to fuck him alone.”

Allyson was breathing fast.  “And where am I, in this little fantasy of yours, Sienna, where you fuck my husband alone?”

“You are my lover, or my enemy,” Sienna said.  “Fuck me, or fight me.  Last night, I hoped for the first.  Now, truth be told, I hope for the second.  I think now Marco will find it very exciting, to see you under my heel.”

With that, she was gone.

It was an eternity to 5 pm. Sienna’s words swirled in Allyson’s mind like storm clouds building.

Fuck me, or fight me.

[catftluver]

Gonna be good, can't wait for next part....

[dcdave]

Gorgeously written.

[catfightfan_2000]

Always beautifully written openings and gorgeous visuals. This is going to be another fantastic story!

[Rocko23]

Excellent set up - onto another winner here! Think it would be nice for the fight to be concluded without Marco present - just different from most of yours.

[snw]

Yes it is another one no doubt.

[JT Edson]

Excellent build up. I imagine the tension is high.

[bcw8]

Allyson was punctual; her key was in the lock at 5:00.  She found herself holding her breath as the door swung open.  Say what you want, Allyson.  Fuck me, or fight me.

“I’m in here.”  Sienna’s voice was so normal, she  could have been greeting her on any day, except it came from the master bedroom.  Marco and Allyson’s bedroom.  Allyson turned down the hallway, practically vibrating with tension.

The au pair longed on Allyson’s favorite chair, a chaise that sat in the bay window.  Sienna’s skin was a lovely hue, a dark Sicilian olive oil.  She had small script tattoos on the front of one shoulder and on one forearm.  At first, Allyson thought she was naked, but as she stretched luxuriously, the blonde saw the thin strap of her black bikini bottom across her hip.  Her breasts were bare, floating on her chest, golden tan with paler triangles.  Her nipples were exactly as Allyson had imagined, dark and jutting.

“I told you to go,” Allyson said.  She put down her bag.

“I am disobedient,” Sienna said.  “Have you decided which offer to accept?”  She stood.  Her breasts swayed, only slightly; they were full but firm.  Allyson thought of the younger woman’s hand, testing the weight of her breast the night before.  “Either choice, Allyson, you are overdressed.”

Allyson nodded.  She unzipped her skirt and stepped out of it and her heels.  Slowly, she unbuttoned her blouse.  She’d worn lingerie today to work, dark plum, lace accents, unusual for her, perhaps unconsciously preparing for this moment.  Sienna watched her undress, a small smile on her lips.  Allyson’s hair and eyes were her most alluring features, but her body was a lovely challenge.  Sienna also thought of her touch last night.  She moved in, until she was only a foot away.

“Just now, I thought of you as a challenge,” Sienna said.  “Have I sensed your choice?”

“I told you to go,” Allyson repeated.  “This is your last chance.”

Sienna bit her lower lip.  “Do you want to slap me, Allyson?”

Three seconds can be a long time.  Allyson’s breath deepened.  “Yes,” she said, softly, finally.

“Do it,” Sienna said, urgently, her voice still low.  “I dare you.  But - if we fight, we fight as women.”  She set her feet and ran her hands over her body, her eyes turned up through dark lashes.  “Slap my tits, Allyson.”

“What?” Allyson said. 

“Do you like to hear me say it?  Slap my tits, bitch.”  Sienna’s dark eyes glowed.  “Then I will slap yours.  We catfight, you cxnt.  You weak slut.  We catfight until one of us is finished”

Allyson hardly registered what she was doing.  Her palm cracked into the outer curve of Sienna’s bare breast. 

Within a split-second, Sienna paid her back.  Allyson’s nipple raked across the lace of her bra as Sienna’s hand drove her breast half out of its cup.

Both women were breathing in hard gasps now.

“I will take your bra and your wedding ring as prizes, slut.  I’ll wear your ring while I fuck your man.”  Sienna was spitting her words now.  She slapped Allyson’s other breast, then grabbed the center of her bra and slung her onto the bed.  Allyson scrambled to her knees, but too late to defend herself as Sienna lunged after her.  The au pair slapped her face, whipping her blonde hair, then gripped it as their bodies smacked together.  Allyson screamed as Sienna dragged her head back, her scalp burning.  Sienna jerked her head to and fro with one hand now, the other slashing down her back, tearing at her bra.  Her breasts spilled free as Sienna broke the clasp.  Her nipples had never been this hard.

Allyson’s hands found Sienna’s dark hair.  It was still slightly damp, from her swim.  Sienna gasped as Allyson’s stripped breasts pumped into hers, as the older woman bared her throat by forcing her face up to the late afternoon light that streaked across the ceiling.  They strained together, deadlocked.

The sensations of the fight washed over Allyson like a storm surge.  The searing pain from Sienna’s vicious hair-pulling - the heat of the younger woman’s hard belly as it slapped and ground against her stomach - the rough blows to her breasts, as Sienna thrust her tits into Allyson’s like two fists.  It hurt, oh yes; but the pain also aroused her.  In their most passionate love-making, she wanted Marco to be rough with her breasts, to slap and squeeze them.  It triggered her, made her wild.  Sienna was hurting her, and oh god she was exciting her.

Sienna rammed her tits into Allyson’s and gasped as Allyson rammed her back, pink nipples stabbing into brown.  It filled Sienna with savage glee.  She had thought Allyson was bloodless, a passive kitten - but this bitch had claws!  Good!  The cool millennial was now gone; Sienna was a Sicilian assassin.  She released Allyson’s hair and raked her face with red-painted nails, the same nails she had run the length of Marco’s throbbing cock.  Allyson shrieked and twisted as Sienna went for her eyes.  The blonde broke away and Sienna rolled from her knees to her ass, planted her foot in Allyson’s stomach, and shoved her tumbling off the bed to crash to the floor.

Sienna flung herself on Allyson, reaching under her chest as Allyson pushed up, stabbing ten knives into her breasts, two dead-center into her nipples.  She rolled, pulling Allyson onto her back, and scissored her waist.  She squeezed, and ripped, her nails embedded, digging deep red scratches in Allyson’s tits as she pulled them apart, left and right stretched out and over the young mother’s ribs.

“Oh you fucking bitch!!”  Allyson screamed.  She clawed at Sienna’s face but it was buried in the side of her neck.  Sienna squeezed harder, and Allyson’s shriek died in a sob of breathless pain. 

“Are you suffering, Allyson?” the au pair whispered in her ear.  “I am just beginning.”  She released her scissors and grapevined Allyson’s long legs, spreading them wide, then wider.  Allyson’s groin and inner thighs seared with pain as Sienna humiliatingly split her, her panties pulling tight into her pussy.  The ten knives still stabbed as well, buried deep in Allyson's titflesh, spreading her breasts the same way..  “What if Marco walked in right now?” hissed Sienna.  “He sees me hurting you like this?  Which of us would he want to fuck?”

“Oh god!” Allyson sobbed.  “Stop it, you little slut!”  She screamed again as the lithe brunette split her legs further.  Even an inch now felt like she was being torn in two.

“You are the one with legs spread, no?  And I am a slut?”  Sienna said.  She dug her chin into Allyson’s neck.  The sight of the American’s body excited her, the tits pulled like taffy and scored by her nails, the heaving belly, the legs like a puppet under her control.  The power of it sent a gush of juices flowing in her pussy.   Another inch.  “Call me a slut again,” she taunted.  “I will break your pelvis, bitch!” 

Allyson could only whimper.  She couldn’t escape the talons in her breasts, she couldn’t counter the agonizing hold on her legs.  Sienna was too strong.  Her head lolled back, her blonde hair fanned out.  She felt Sienna’s tongue flick at her ear.  “Are you done, Allyson?  Already?  No wonder your man strays, weak bitch.”  A final, excruciating inch - then she pushed Allyson off, into a lump on the carpet. 

Sienna stood, her own thighs trembling.  She put her foot on Allyson’s neck.  “You have never fought another woman, have you, Allyson?  You regret your choice?”  She put her weight on it, drawing a strangled moan from the older woman.  “To have a man is sweet.  To take a man from another woman is sweeter.  To fuck your husband after dominating you, you arrogant, smug, superior cow - oh, Allyson, that is heaven.”

[Rocko23]

Wow. That was great the comment re the ring was amazing trash talk. Hope that's not the end - and if it's not I hope that Allyson gets in a lot more offense. I'm not that fussed on who wins this as long as the gals do a lot more damage to each other lol.

[bcw8]

Allyson could barely breathe, and as Sienna bore down, grinding her bare foot into Allyson’s neck, bright bolts of pain shot up into her skull, exploding like fireworks in her brain.  She clawed at the Italian girl’s ankle and calf, but Sienna only twisted her foot more cruelly.  Allyson tasted the bedroom carpet in her open mouth. Her breasts and thighs ached.  Helpless and humiliated, she sobbed as Sienna bent for handfuls of her hair, twisting her long blonde waves around and through her fingers in an unbreakable grip.

Sienna moved fast, dragging Allyson across the room on her stomach, enjoying how the carpet burned her downturned tits, how it rubbed her pink nipples to a raw, fiery red, how her fucking panties were pulled halfway down her ass.  She reached the doors to the private patio outside the bedroom, lifted and slammed Allyson’s face into it, her breasts swinging and slapping the glass.  With Allyson now up on her knees, she slapped her ass hard, adding to her humiliation.

“Do you like being spanked, bitch?”  Sienna smeared Allyson’s face back and forth on the glass, watching her tears streak, her breasts flattened and dragged.  “I listened last night, when you sucked Marco.  I was amazed he got it up at all - he must have made himself think of me.”  She dug her nails into Allyson’s ass, hard.  “I gripped his ass like this while he fucked my mouth, when he filled it with his hot cum.  I loved your fury when he had none left for you!  I told you,I milked him dry.”

“Shut up,” Allyson sobbed.  “Shut up shut up shut up!”

Sienna laughed, gleefully.  She knee-walked Allyson the few steps to the chaise, and reclined on it, still with a death grip in Allyson’s hair.  She pulled her face between her olive thighs, tugging aside her bikini.

“You chose to fight, not fuck,” Sienna said.  “But you are a terrible fighter.  Are you better at fucking?  Lick my pussy, you whore.”  Allyson’s moan was muffled as Sienna pussy rubbed over her mouth.   The slightly musky sweetness of the Sicilian’s juices wet her lips.  She felt the nub of Sienna’s clit throb against her tongue.  “Suck it,” Sienna ordered, her voice thick with lust and power.

She thinks she’s beaten me, Allyson thought, and that thought enraged her.   

Sienna screamed when Allyson bit down on her clit.  The shock and sudden savage pain of it was otherworldly.  Her heels hammered against Allyson’s back.  Her hips heaved and twisted.  Somehow, she resisted the urge to use her grip in Allyson’s hair to jerk her head away, instinctively understanding that would tear the hypersensitive flesh that the American crushed in the vise of her  perfectly polished teeth.

Mocked me.  Taunted me.  Have you never fought another woman?  Have you ever had you pussy bitten, bitch? 

Sienna bucked, her pubic bone crunching into Allyson’s nose like a fist.  Allyson cried out in pain, and Sienna thrust her away the second her teeth opened.  Allyson fell back but lunged up to her feet, her fury driving her.  She flung herself on the half-risen Sicilian, smashing her back onto the chaise, her nails slashing Sienna’s bouncing tits.  Allyson drove her thumbs into their dark centers, twisting them.  Sienna screamed again, a high panicked wail.  Allyson pinned her on her back, her dark head lolling off the side of the chaise.  Cat-lust surged through the older woman as her nails tortured Sienna’s tits, digging into her like tiny spades in a garden of soft earth.  The first sight - and smell - of blood as she worked at the roots of her foe’s stiffened nipples made her dizzy with exhilaration.

She raked Sienna once more, enjoying the sudden relief in the younger woman’s eyes as her nails left, because she knew how short-lived that reprieve would be.  She slammed her chest down into Sienna’s, flattening her slashed tits with hers, and snaked her arms under her back.  All her one hundred thirty pounds.  All the power her arms could muster. Cheek to cheek, body to body.  She squeezed Sienna in a horizontal bearhug.  She felt Sienna’s firm young tits give under hers, felt her nipples soften and surrender to her own, felt her sweat-streaked belly heave with sobs, felt her tears of pain.

“What if Marco walked in now?” Allyson snarled.  She ground her clit against Sienna’s, the lace of her panties and the fabric of Sienna’s damp bikini like sandpaper.  “Who will he want to fuck?”  She turned her head and bit Sienna’s earlobe.  Sienna screamed and thrashed but Allyson choked that off, tightening her arms.

“Oh god . . .  my tits!” Sienna sobbed.  “You are crushing my tits!”  When she sobbed again, Allyson tightened more.  Sienna made a harsh sound of animal pain, her struggles subsiding.  Allyson imagined a stubborn stain, a spot of dried filth, and how she would rub it out.  That was what her nipples were doing to Sienna’s nipples, trying to scrape them away.

Sienna suddenly and violently thrashed.  She set her claws in Allyson’s back and ripped.  Allyson jerked in pain and screamed.  She felt blood oozing from the burning scratches.  Then the heel of Sienna’s hand wedged under her chin, and slowly forced it up.  Once Allyson’s throat was exposed, Sienna clawed it with her other hand.

Allyson lifted her hips and pounded her clit down into Sienna’s.  The dark girl jerked and lost her hold.  The spasm ground their nipples together, buried in the piled of compressed breasts.  Sienna moaned, and wedged her hand under Allyson’s chin again.  This time, before Allyson could retaliate, she raked at her face, her thumb stabbing at the blonde woman’s blue eye.

Allyson screamed and flung back, her back hitting hard on the glass door.  Sienna kicked wildly at her, her heel pounding hard into her right breast, and rolled off the chaise in the other direction.

They lay apart, sobbing.  Allyson held her watering eye; Sienna cradled her battered breasts.  Twenty minutes had passed since Allyson had arrived.  As if on the same silent signal, both women pushed up and staggered into the open portion of the bedroom.  Allyson reset her panties, high on her hips.  Her breasts were red; her eye open but swelling.  Sienna breasts were puffy, and vividly bruised, even with her olive skin.  She winced as she pulled her bikini back over her mound.

“You bit me, you bitch,” Sienna said, and her voice was a nest of wasps.  Her fists balled into small stones as she raised them.  “Now I will beat your fucking face.  When Marco arrives, he won’t even recognize you, much less want to fuck you.”

Allyson thought inexplicably of the twins, then fiercely pushed them from her mind.  Marco.  Marco, and this house.  It was her house.  This little dark cxnt had infiltrated her house and sucked her husband's cock and challenged her to fight and hurt her so now it is her or me! her brain screamed at her.  She clenched her fists and brought them up.  “Come at me, you little cxnt,” she said.

[Rocko23]

Great to see fight back! Enjoyed the biting as well. Hope the bottoms get ripped off and that they try and destroy each others wombs. Looking forward to this getting even bloodier and nastier!

[DoubleT2]

Clearly Siena has referred to at least one previous catfight she’s had. Would really like to hear more of that story(ies) if possible. Love the primal brutality.

[justlooking9000]

As always, a hot set up and a very sexy story from the get go. I can't believe how fast you can churn out these stories and with such good quality.I usually don't start reading stories until I see that the author has finished them, but I gone and started reading anyways. At the point in which I was before I made this post, it seems like Allyson is about to lose her husband to the younger woman.

[cflover]

Fantastic story!   And beautiful girls!

[bcw8]

Neither woman was trained at this, but rage and ferocity mean much more than skill. They stood in the center of the room between the foot of the bed and the large oak dresser and hammered at each other, fists into faces.  Their hair whipped when punches landed.  The rings they wore cut.  Their knuckles split soft skin.

Allyson’s eye was nearly swollen shut now, because the lithe young brunette’s small fist battered her cheekbone and cut her eyebrow.  Her lower lip was gashed.  Her nose bled.  Neither was trained but Sienna was better.  Her cheek bore a deep cut from Allyson’s diamond, but her eyes were clear and for every two blows Allyson landed, Sienna landed three.  Allyson wobbled, dazed, punch-drunk.

“I said to you,” Sienna gasped.  Her fist lashed into Allyson’s mouth.  A line of crimson blood drops flicked across the white bedspread.  “I wreck your face.  Now your body.”  Allyson screamed, and crumpled as a vicious punch exploded into the center of her left breast.  Sienna caught her hair, then curled her into a headlock.  Allyson scrabbled at the arm around her neck.  Sienna grabbed her wrist with her free hand, then slipped her grip to Allyson’s fingers.  Too late, Allyson tried to clench her fist.  Sienna had her ring finger, and was bending it back to the snapping point as she worked Allyson’s diamond ring free. 

“I also said to you,” Sienna said, her voice harshly triumphant.  She had the ring.  She jammed the diamond and the prongs of its setting into Allyson’s face, using it to cut her cheek. Then she deftly manipulated it onto her own finger, the middle one in the center of her fist.  Trapped in the headlock, Allyson was doubled forward at the waist.  Sienna uppercut her dangling breast, driving the big one-carat stone dead-center into Allyson’s nipple.  Her fist rebounded a few inches as Allyson’s body took the impact, then she jammed it back into the blonde woman’s breast, twisting it back and forth.

Allyson screamed as if she’d awakened in hell.  Her ring, the ring Marco had given her on bended knee eleven years before, the symbol of his love, now wielded by the girl who sucked his cock, was a diamond drill tip shredding her nipple even as Sienna’s fist crushed it.

“He will be home soon,” Sienna said.  She twisted to uppercut Allyson’s other breast, to screw the ring deep into that nipple too, then slammed the wife into the wall, pinning her to it with fingers wrapped around her throat.  “Your face is bleeding,” Sienna said, with mock concern.  “So are your saggy tits!  Marco will be disgusted by you, I think.”

“Fuck you, Sienna,” Allyson managed.  “You’re bleeding too.  You’ll bleed more.”

Sienna’s fist, and her ring, smashed deep into her stomach.  Once, twice, three times.

“You are too old for more babies anyway,” the Sicilian said.  Four - five - six; brutal gut punches.   “Marco and I would make beautiful babies, yes?”  Seven - eight - nine; angled lower, into her pantyline.  “When he divorces you, maybe I take the twins, too, Allyson.” Ten - and it was the worst of all, the words and the fist. Sienna stepped back, at last, and let Allyson collapse bonelessly to the floor.

They both heard it, though if Allyson’s ear had not been pressed to the floor, she might not have separated it from the agony roaring in her brain.  It was the garage door.  It was Marco.

“He’s early!” Sienna said delightedly.  She kicked Allyson hard in the ribs to flip her onto her back, then stomped her low in her belly, just for fun.  “Up here, Darling!” Sienna called.  She put her foot on Allyson’s neck again.

He can’t see me like this, Allyson thought. No. Please, God.  The arch of Sienna’s foot bore down on her, crushing her windpipe.  Desperate panic seized her.  She bucked and fought.  Sienna lost her foothold, which infuriated her. She wanted Marco to find her in an utterly dominant pose over his fucking wife. Stomp her again, Sienna thought.  She lifted her foot.

Allyson grabbed it, at her heel and at her toes, and wrenched as hard as she could. Sienna screamed as her ankle and knee twisted.  Allyson swept her leg into Sienna’s planted one. The dark girl crashed to the carpet.

On the stairs, Marco heard the scream, and the crash.

Allyson saw her discarded bra, only feet away. She snatched it up, and wrapped it around Sienna’s throat. 

Marco opened the bedroom door to see his wife, stripped to her panties, her face bloodied and her breasts cut and battered, strangling their topless au pair with her bra.

The evolved, higher part of his brain told him to pull them apart. The lizard part of his brain pumped blood to his cock. It may have been the lack of blood flow that caused the higher functions to rationalize:  let them settle it.  Whatever the reason, as he took in Sienna’s sweat-streaked tits heaving as she fought for air, as he registered how erotic the curl of Allyson’s lips were around her clenched teeth, the lizard won. He unzipped his slacks, took out his already-raging erection, and leaned back against the wall to watch.
