Slept With My "Sister's" Men

Stella's POV

The rain had been relentless for three days, Seattle's gray skies bleeding into slick streets like a faded photograph smeared by tears. I'd discovered the texts two days ago—pure accident, swiping through Mason's phone while he showered after one of our "perfect" date nights—and the betrayal had hit like a gut punch, confirming what I'd feared: he was cheating, not with some stranger, but with Emily, the girl I'd let into our lives over months of dinners and brunches, believing her to be the sister I never had. Standing outside his apartment at 5 a.m., key card trembling in my hand, I drew a ragged breath that burned—this wasn't planned revenge; it was raw hurt demanding retribution, even if I had to fake the tears to get it.

I slipped inside quietly, the door sealing behind me with a soft click, the air thick with stale beer and his cologne, the bottle I'd gifted him now a mocking reminder. Curling on the leather couch, phone clutched like a weapon, I stared at ceiling cracks webbing like my fracturing trust, legs numbing over two and a half hours as rain drummed the windows, each drop amplifying the ache in my chest. This wasn't The Hive's cold precision; this was personal, messy, the kind of pain that made even a girl like me—scraping by on two jobs for Mom's bills—question if anything was real.

At 7:45, bedroom rustles stirred me—sheets shifting, a groan—and adrenaline flooded hot, my pulse thundering as I rose, hand hovering on the door handle—one beat, two, three—before shoving it open. The sight slammed into me: Emily's golden hair fanned on his pillow, her bare shoulders arched, sheets tangled around their naked sweat-slicked bodies, the air reeking of fresh sex and whiskey, red scratches raking Mason's chest from her nails digging deep in ecstasy I hadn't known about until now.

I froze, a gasp ripping free, eyes widening in true horror. "Emily?" My voice shattered, no act needed. "Mason... you fucked my best friend? In our bed?"

Tears scorched down my cheeks, unbidden, as memories crashed—nights I'd introduced her as my "ride-or-die from home," double dates where I'd laughed at their flirty banter, girls' nights spilling into his bar, Instagram stories we'd curated together, me weaving her into our world so tightly I'd trusted her implicitly, only for her to repay it by riding him.

Emily bolted up, sheet clutched to her heaving breasts, voice pitching desperate. "Stella, oh God—I'm so sorry, it just happened last night, he was drunk after the party, I swear I didn't plan—"

"Get out!" I screamed, voice cracking raw, hurling her clothes at her as she scrambled naked from the bed, full tits bouncing, round ass jiggling in panic, heels clattering until she fled the hall.

Mason lurched upright, cock still slick and semi-hard from her pussy, stumbling toward me with slurred pleas. "Babe, wait—she seduced me, I was wasted, you know how I get—please, Stella."

I backed into the doorframe, wood digging into my spine as sobs wracked me, his betrayal carving deeper than any scar from my side gigs. He pulled me close, naked body pressing hot against mine, lips brushing my neck in frantic apology, his dick twitching against my thigh—a humiliating twitch of arousal amid ruin. "You knew she was my everything," I whispered, voice splintering, even as his hands roamed my waist, slipping under my shirt to cup my breast, thumb teasing my nipple to a traitor peak through lace, my body flooding wet despite the rage. He kissed me then, tongue invading with her taste lingering, one hand hiking my skirt, fingers probing my soaked folds, two digits thrusting deep into my clenching heat while he ground his erection on my hip, murmuring, "Let me make it right, baby—fuck the pain away, I'll do anything."

Revulsion surged as his cock nudged my entrance, slick from her sliding toward my own wetness—God, the shame burned as I moaned involuntarily around his plunging fingers, walls pulsing, but I shoved him back hard, skirt falling, tears streaming. "Don't—after her? You're disgusting."

We tumbled to the living room, me curling on the couch knees-to-chest, thighs slick from his violation, while he knelt naked, groveling, softened cock dangling pathetically, apologies slurring into begs. Minutes dragged until his guilt twisted ugly: "I fucked up, okay? But without my Boeing and Microsoft connects, Stella? Community college trash like you—"

The slur ignited me. I flashed his phone's Chicago gala receipt—the redhead's hotel bill I'd glimpsed earlier. "And this? Done."

His face paled, eyes flickering shame to resolve. Instead of rage, he grabbed his wallet, yanking a thick wad of hundreds—twenty grand crisp—and tossed it onto my lap, bills sticking to my tear-damp cleavage where my shirt gaped. "Take this for now," he muttered, jaw tight with self-loathing heroism. "For your mom's treatments. And..." He pulled out his banking app, fingers flying, my phone buzzing instantly: $200,000 transferred. "Selfless me, right? Covering your sob story bills. But we're done—you're just a whiny bitch who got too close."

He loomed, fisting my hair to yank my head back, forcing my gaze while cash fluttered like dirty snow. "Pluto—bitch, I've wired the money to your account. Now get the fuck out."

He shoved me away, storming off. I gathered the bills—twenty grand easy—amid the humiliation, body trembling from his touch's ghost between my legs, the "generous" transfer a crown of scorn. Account now $680k: his guilt money plus my side-hustle savings—enough to finally cut ties with my shadows, and vanish into the real fight ahead.
