Chapter 1 - The temptation of Sinclair siblings
Emma really hadn’t meant to find it.
She had only been looking for the tax return to send with her NYU Law school application. She had been asking Mom, who had forgotten to send it to her. With the deadline looming, she really needed it today. She had been texting Mom who had gone for her monthly book club (really, Mom?) and had said to go to her laptop and take it from the folder ‘Tax Returns’. Mom was the one that did taxes since she had studied to do as a CPA. However, now she was a part-time interior designer and wellness therapist and worked from the basement.
“Take it from the laptop. Should not have password,” texted Mom.
“Ugggh!” grunted Emma.
The house was empty when Emma went into her parents’ office. It was plush, carpeted, with wooden panels. Mom was the interior designer. The office had Dad’s big table where he worked, and with her mother’s table at the corner. Her mom’s laptop was open on the table. Her dad, Mark, was a corporate lawyer working as Chief Counsel at an IT firm headquartered in NYC but with a local office. Mom always worked from home, and Dad worked at home on Mondays and Fridays, though he did take more days to work from home, the normal post-Covid routine.
She opened the device (and as Mom said - no password) and immediately tapped into folders to see the tax returns. There it was! She opened the browser to email these to herself.
And then she saw it on one of the open tabs.
Open Tabs: OnlyFans - @Mrs.SinclairXXX
Emma froze.
Her mouse hovered over the tab, torn between horror and a deep, undeniable curiosity. Her mother, her own mother, was watching OnlyFans? Or did she have one herself? The woman who hosted school fundraisers and scolded Emma for wearing crop tops to school?
Before she could stop herself, she clicked on the tab
The page loaded with excruciating slowness.
And then, she saw.
Oh. My. God.
There she was.
Sarah Sinclair, splayed across a leather couch Emma recognized from their basement rec room. Her mother’s body was shimmering under soft lighting, her deep red nails clutching the cushions as a thick, veiny cock was deep inside her. The video thumbnail was frozen on her mother’s face smiling at the camera.
Then she clicked play.
"Fuck me harder for the camera, baby."
The words filled the room and came from the speakers before Emma could stop them. Her mother’s voice, low, breathy, filthy. She tried to remember if she had ever heard her mom even cuss or say fuck. She couldn’t. And then the moan, she moaned so hard. Emma remembered hearing that when Mom and Dad were being gross at night.
Emma’s entire body went rigid. And hot.
She should have closed it. Should have shut down the browser. Should have pretended she never saw anything.
Instead, she turned the volume up a little, now curious to see Dad. And then the shock. That cock didn’t belong to Dad! It was a stranger! Mom was fucking someone else in our basement!
The video played in full, unforgiving detail. Her mother was looking at the camera as she got fucked in different positions, her throat was working around the cock that stretched her lips, her manicured fingers were kneading her own breasts. Emma couldn’t look away. Couldn’t breathe. Couldn’t believe. The video had her in a trance, like it was a magnet so strong she couldn't look away even if she wanted to.
And then worst of all, she realized she was wet.
She was aroused like never before, her thighs pressing together instinctively as her body reacted to the sight of her mother being used like a common whore.
No. not common.
Expert.
Because Sarah Sinclair didn’t just bear it. She owned it.
Emma unconsciously opened her jeans' button and moved her right hand under the waistband of her panties. She was surprised the moment her fingers met her pussy to find how wet she was. She quickly withdrew and looked at her fingers, then put it back inside her panties.
"Oh my god, Mom..." she whispered, her thumb circling her clit and fingers entering her pussy, as she watched the unknown man on screen pull her mother’s hair, forcing her to look into the camera as he fucked her throat while she was on her knees and the man was standing.
She should have been disgusted.
Instead, she was transfixed.
And the stranger was cute. Younger, maybe her age.
Emma’s breath was ragged, her fingers stroking faster, her clit enlarged. She could barely recognize the sounds coming from her own mouth - whimpers creating an accompaniment to the sounds of mother’s grunts on screen, as the sensory overload of sound, vision and touch was becoming overwhelming.
When she came, it was with her mother’s moans still ringing in her ear, her back arching, her thighs clamping around her own hand, her entire body shuddering with pleasure she knew was wrong but couldn’t bring herself to regret.
The moment the haze cleared, Emma moved to change the tab, leaving traces of her ever being there.
She went back to her room and couldn’t take out that memory. It was burnt in her mind - her mother. She opened her laptop, opened OnlyFans and subscribed immediately to her mother “@MrsSinclairXXX” - wow she was using her real name - that was guts.
She watched a few more videos, her feelings ranging from disgust to thrill, and said to herself, “Enough!” and hovered her mouse on the Unsubscribe button.
But she didn’t delete her subscription. She couldn’t do it.
----------------------------------------------
Emma's fingers trembled as she held her iPad and scrolled through the shocking gallery and video of her mother's OnlyFans content. The initial horror had transformed into something far more dangerous - a deep, primal arousal that was making her wetter with each new depraved image and video.
She played a video titled ‘Mommy Got Needs,’ and forwarded to the middle of the video.
"Mmm…right there baby, stretch Mommy's tight little pussy," Sarah Sinclair moaned from the tablet screen, her body writhing beneath a well-hung youngster with a Jesus fish tattoo on his shoulder. Emma watched, entranced, as her mother - the same woman who baked apple pies for school functions - pulled her legs obscenely back to her ears in order to accommodate the stranger's cock.
Without conscious thought, Emma's own fingers slipped again beneath her cotton panties, feeling her own wetness and arousal. The sounds from the video seemed impossibly loud in her quiet bedroom as her fingers found her swollen clit.
"Oh fuck..." Emma whimpered, watching her mother's breasts bounce with each thrust. "How...how does she take it so deep?" she thought. She imagined that youngster cock in her and moaned at the thought as she saw her mom getting fucked.
She shut it for now.
Emma, 22, a recent college grad and a paralegal at a local law firm, found it difficult to concentrate on her LSAT prep. She wanted to do law like her father, Mark, who was a corporate lawyer and Chief Counsel at an IT firm. But now her mind kept drifting to her mom’s OnlyFans account.
For five agonizing nights, Emma had consumed every video with ravenous hunger. She'd watched her prim-and-proper mother do things that made her sheets so wet - taking two cocks at once, moaning with a mouthful of cum, screaming filth as strangers drew intricate patterns on her bare skin with ice cubes or Nutella or wine before licking them clean, women pleasing her, she pleasing women. It seemed no act was off the table, as long as she was doing it for the camera.
On the sixth night, disaster struck.
Emma's finger hovered over the tablet screen and had just clicked the next video titled 'Mommy Takes Two Black Cocks - Full DP Scene' when her bedroom door burst open without warning. She barely had time to throw the comforter over her lap before Lily, her youngest sibling, and high school senior all of 18 years old (Eighteen years and 3 months as she tended to remind everyone) barged into the room.
"Em? I just wanted to grab your…" Lily's words died mid-sentence as their mother's distinctive voice emanated from the tablet speakers. The color drained from Lily's face as her blue eyes focused on the screen where Sarah Sinclair was on her knee in the basement couch, her signature red nails around two massive black cocks, one in each hand, as she sucked them alternately.
"OhGod, OhGod, Close it!" Lily hissed, practically teleporting to the bed to press the off button at the side of the iPad. She stood trembling, her hands pressed over her mouth, sleepshirt hanging off one shoulder.
Emma watched as Lily's chest rose and fell in rapid bursts - not with disgust, Emma realized, but with...arousal? The way her sister's nipples peaked visibly beneath her pajama shirt confirmed Emma's suspicion. Lily wasn't horrified. She was as fascinated as Emma was when she was when she first saw this.
When Emma slowly reopened the iPad, Lily didn't stop her. Instead, she crawled onto the bed, her knees brushing Emma's beneath the covers. They sat shoulder-to-shoulder watching in stunned silence as Emma forwarded the video to show their petite mother take two massive black cocks simultaneously - one in her pussy while she deepthroated the other.
"Fuck Mommy's nasty holes," Sarah grunted on screen as the cock in her pussy thrusted in and out, her breasts moving obscenely. "I want to be your slut, boys!"
Lily made a choked sound. "She...she'd kill us if she knew we..."
"She won't." Emma's hand found Lily's, holding it like they always held hands. Emma, always the elder sister, was guiding Lily’s hands beneath the comforter to press against her own damp panties. "Feel how wet I am, Lily. You know you are too."
Lily whimpered but didn't pull her hand away. Their fingers tangled together over Emma's soaked cotton as they watched Sarah scream through an intense orgasm, her legs shaking around the thick cock fucking her.
The moment stretched between them, thick with tension, sisters not saying anything. It seemed Sarah’s orgasm had quietened the room. Then, Emma instinctively shimmied closer to Lily, their bodies pressed together. As they pressed closer, they could feel the heat between them as they took ragged breaths.
Emma then turned to face Lily and brought Lily's face to face her. She searched for any hesitation or resistance in her sister's eyes. Instead, she saw desire, lust and acceptance. She leaned in closer for a kiss, and wanted to do it slowly. But when their lips met, it was anything but delicate or tentative. It was a hungry, full-blooded, tongue-dueling kiss that took them by surprise. A good surprise. Lily moaned into the kiss, her tongue dueling with Emma's like getting back with an ex, and not your own sister for the first time. The taste of her sister, spearmint toothpaste and something uniquely Lily, sent electric currents straight to Emma's core. She'd imagined a moment with a female a thousand times since discovering their mother's videos with other women, but never dreamt it would be Lily, her younger sister. And the fact was that Lily kissed back with equal fervor, her hands rising up to get purchase in Emma's hair to hold her closer.
They parted with a longing and looked at each other, looking to the other where this leads now. They heard their mom groan on the screen as the men switched positions. The two sisters looked at each other again. Keeping her eyes peeled on Lily , Emma removed the comforter completely, exposing her pussy to her younger sister. Lily, hooked on to the view of Emma's pussy, asked her elder sister, "Show me how you touch yourself when you watch Mom's videos."
The way Lily's breath hitched would fuel Emma for weeks. Emma put her hands on her pussy, and masturbated, inserting one finger inside her slick folds, and the thumb on her clit. With the other hand, she brought Lily’s hand to her pussy. With hesitant movements, Lily traced Emma's swollen lips, copying the motions her sister was doing.
"O-Open wider," Lily whispered. Emma did so. Lilly placed her hands on her exposed pussy, tentatively tracing it with two fingers. And when Lily's thumb touched Emma's clit, Emma let out something between a gasp and a moan..
"Yes! Just like… oh, fuck…just like Mom likes it!"
Lily shuddered violently at the comparison but didn't stop. Her touch grew bolder, exploring Emma's dripping entrance before replacing Emma’s fingers and pushing her two fingers inside.
Emma cried out, her hips bucking. "Oh God, Lily! Deeper!"
On screen, their mother came violently again, her pussy clutching around the cock pumping into her. The sight pushed Emma over the edge, her orgasm wracking her body as Lily fingered her through every pulsing wave.
When Emma finally stilled, she rolled Lily onto her back without preamble. "It’s your turn, little one.” Little One. This was Emma’s way of teasing Lily especially when she declared she was an adult. She stripped Lily's panties with one sharp pull, and Lily helped her by arching her back. Without a thought, she put her mouth to Lily’s pussy. The moment Emma's tongue touched Lily's wet folds, Lily moaned, and Emma made a complete lick. "Oh fuck, little one...so sweet."
She worshipped Lily's pussy with all the skill she'd learned from experimenting with her girlfriends in college and watching their mother's videos - circling Lily’s clit with firm strokes before sinking deeper to tongue-fuck her like the men and women did to Sarah. Lily thrashed beneath her, chanting profanities Emma had never heard from her younger sister.
"OhGodOhFuck! Emma! Right there! Make me cum. Make me cum. Fucccck."
"Cum for me like Mom does," Emma said against her clit, sucking hard while pushing three fingers inside now. "Show me what a dirty girl you are!"
Lily's back arched clear off the mattress as she climaxed violently, her juices dripping down Emma's chin. As she lay back panting, Emma crawled up her trembling body, kissing her deeply to share the taste. Surprisingly, Lily kissed back.
On screen, Sarah was swallowing a thick load, her tongue slaking the tip as she milked every drop. Emma groaned at the sight before turning back to Lily.
"Tomorrow night," she whispered, "we do everything we see Mom do. Everything."
Lily's answering moan was all the confirmation Emma needed.
----------------------------------------------
This went for two more nights. The sisters got together at night and watched Mom on her OnlyFans account.
On the third night, the door creaked open without warning (did Emma leave it open on purpose to be discovered?). Jason had seen the two sisters discuss conspiratorially at dinner, and disappear. He began to wonder what they were scheming. They were always close, but not that close. In fact, Jason was closer to Emma than Lily was - and not just by age. Although Jason also got along with Lily. He loved being their protective brother. And the girls did gang up on him from time to time.
Jason stood at the doorway - frozen as he looked at what was happening inside. His jaws dropped as he saw his sisters were naked and eating each other in a sixty-nine. There was a laptop open where their mother was currently being double penetrated by two well-hung black men. His eyes went from sisters to screen to sisters and back to screen. He was riveted, with eyes looking like following a tennis match.
"Jesus H. Christ," mumbled Jason under his breath. His breathing was ragged, and he held the doorknob so hard; his knuckles were becoming white . "Are you guys watching porn? On OnlyFans? What are you two doing together? Is that... is she...No!"
"Mmm, yeah," Emma said, almost defiantly, not even bothering to pause the slow circles she was drawing on Lily's clit. "That's Mom. Your sweet, innocent mother. And that’s her OnlyFans."
The sounds from the iPad were obscene, skin slapping against skin, their mother's moans of "Oh yes! Fuck me harder! Fuck both my holes!" The camera zoomed into her pussy. The man who was fucking her took out his massive, shining wet cock covered with her juices out of her dripping pussy. He held that pose before thrusting it back in her - a show just to highlight how big he was and how much she enjoyed taking the massive cock.
Jason took in a massive breath. Emma watched with fascination as Jason's eyes remained locked on the screen watching his mother do unmentionable acts to show the world. His first instinct was disgust and revulsion, but he couldn't help looking. Jason was the middle brother, twenty years old and going to the city branch of University of Wisconsin, studying Chemistry. Emma saw that his 6'1" frame trembled slightly, but what relieved her most was the unmistakable tent starting to appear in his gray sweatpants.
Lily was nervous and squirmed nervously beneath Emma. "Jay, we... we didn't mean for you to..." Her words trailed off as she noticed her brother's condition too. "Oh."
Emma couldn't resist. "See something you like, big brother?" she teased, deliberately spreading Lily's folds with two fingers to show off how wet Mom’s video was making their baby sister.
Jason shook his head as if this would erase everything he just saw.. "This is... this is so fucked up. That's our mother! And you two... you're..."
"Enjoying the show?" Emma replied helpfully, clicking to another video where their mother rode a thick strap-on attached to a busty blonde woman. "Or should I say... shows?"
Jason fell silent, but his eyes remained glued to the screen where his mother threw her head back in ecstasy, her perfect breasts bouncing with each thrust, the woman with the strap-on was making inside her. Emma watched as he gulped hard which made his Adam's apple bob in his neck.
"Look how much she loves it," Lily whispered. She was transfixed both by the scene playing on the screen and also by how Jason's cock visibly twitched in his sweats. "Do you think... do you think she'd let us watch her live sometime?"
Jason actually whimpered at that, his whole body tensing. "We...
