The weekend had started out perfectly. Kelley had taken off work early and driven to the family cabin on Friday afternoon to set up. She’d been planning this, well, all year, really, and she wasn’t going to leave anything to chance.

The cabin was deep in Les Laurentides, several hours north of Montréal. The real name of the area was Val des Lumières but among the Hayes family, it was simply “up Val”. She’d stopped in Sainte-Agathe-des-Monts for last-minute supplies—charcuterie supplies, an artichoke dip and a boule that smelled like heaven, and wine, so very much wine.

“To my little sister!” Kelley announced, raising her glass. “My new literary agent!”

“Kel!” Kayleigh giggled, clinking glasses then taking a rather large drink of the grenache-heavy rosé. “It’s April, at least wait until I know if I graduated!”

Kelley giggled too, finishing her wine, collecting Kayleigh’s glass and heading back to the kitchen to refill both from the second cardboard box of the evening. “No way! I hate my agent, if I’m gonna get screwed by anyone—” she cut herself off and glanced nervously at Kayleigh.

Kelley’s little sister blushed, then beamed. “Get over here, Bossy Boots!”

Arching an eyebrow, Kelley returned to the living room with the two full glasses of wine. She sat down carefully and snuggled up to her sister before the wood stove. “I’m bossy?” she teased as she brought her lips close.

“You used to be,” Kayleigh replied softly, then kissed her sister full on the lips while one hand cupped Kelley’s behind. Before long the wine was forgotten, clothing was discarded and the sisters connected in their own, unique way.

The clock on the nightstand glowed 2:22 AM, casting a faint red hue over the bedroom Kelley and Kayleigh were sharing this weekend. Kelley dozed when they first came to bed, but the heat refused to die down. The moment Kayleigh lay down on the decadent mattress, she was asleep. But Kelley, she still needed her sister. She had planned one more treat but the wine, the long drive, and weeks of Kayleigh wrapping up assignments and finishing exams had gotten the better of little Kaybear.

Kayleigh snored softly on her side of the bed, her lithe body barely covered by a thin tank top and panties—she had kicked the duvet off within minutes. Kelley watched her, heart pounding, the strap-on she’d bought months ago—the final surprise, hidden in a drawer—wouldn’t leave her thoughts. The dildo was a monstrous thing, 8 inches long with a tapered tip, a bulbous, knotted centre, then a ribbed and veiny shaft back to the moulded testicular base. Jean-Claw, it was called, a hand-sculpted dildo mounted in a hand-tooled leather harness.

Get over here, Bossy Boots!

Kelley slipped out of bed. “Bossy.”

Kelley retrieved the silk ropes from under the mattress, the simple sight of them fuelling her arousal. The ropes were a regular part of their games but never like this. She worked quickly, securing both of Kayleigh’s ankles to the bed before the younger sister even stirred.

“What—” Kayleigh’s groggy question died as Kelley looped the rope around her wrists, tying them to the headboard with practised knots. Kayleigh squirmed, her small breasts heaving under the tank top, nipples poking up beneath the fabric.

“Shh-shh-shh, Kaybear,” Kelley murmured, her voice the familiar warning tone from childhood: Kayleigh would catch Crinklebone Fever if she didn’t leave Kelley and her friends alone during sleepovers. Kayleigh relaxed, just a little, until her big sister held up a whiffle-ball-gag. As she opened her mouth to speak, Kelley forced it between Kayleigh’s lips and fastened it behind her head. Kayleigh’s eyes widened, the bright red gag distorted her words to wet burbling.

Kelley’s hands explored, yanking Kayleigh’s tank top up to expose her modest tits, pinching the ruddy pink nipples. Kayleigh bucked her hips. Kelley watched her eyes and told herself what she saw there. She hooked her fingers into Kayleigh’s panties, tearing the silly lace things away, exposing the red whorls of dense pubic hair.

“You’ve always been mine,” Kelley growled, moving back and off the bed, giving Kayleigh a clear look at the strange, eldritch phallus her sister wore. Kelley knelt on the bed between her sister’s open thighs, grinning. “You always knew that, didn’t you, Kaybear?” She tightened the restraints on Kayleigh’s ankles, forcing her thighs apart until her wonderful sister squeaked in protest and her pussy lips parted, revealing glistening pink inner folds.

Kayleigh’s muffled cries filled the room as Kelley rubbed the Wendigo cock against her entrance, the knobbly tip teasing Kayleigh’s clit before pressing in. The head breached slowly at first, Kayleigh’s breath coming in sharp, shallow pulls as her body arched and the ropes creaked against her struggles. Kelley pushed deeper, and when the knot finally bore through Kayleigh’s entrance, the younger woman whimpered through her gag.

“Fuck, Kaybear, I can barely get inside,” Kelley panted, her hips drew back then snapped forward, beginning a rhythm. She pounded into her sister, the strap-on’s girth splitting Kayleigh open, juices squirting out with each thrust. Her gagged moans turned to sobs of pleasure as Kelley drove the knot in, revelling in the minute resistance each time she pulled it back out, like she might turn her sister inside-out.

Kelley’s hands mauled Kayleigh’s tits, twisting the nipples as she fucked harder, the bed slamming against the wall. “You’re so fucking pretty,” Kelley gasped. “I love your titties so much!” Sweat dripped onto Kayleigh’s heaving chest. She reached down, rubbing Kayleigh’s swollen clit in tight, rough circles. Kayleigh’s body convulsed, her bound limbs straining, and Kelley knew. She watched her sister come apart, girl-cum gushing, soaking the sheets.

Kelley didn’t stop. She flipped Kayleigh onto her stomach. The ropes didn’t allow enough slack, so Kelley’s little sister was cross-armed and cross-legged, face-down. As Kayleigh mewled in protest, Kelley re-entered her from behind. The new angle drove the strap-on deeper, as Kelley slapped her sister’s firm ass-cheeks red. “Take it all, Kaybear,” she hissed, grinding the base against her own clit for friction. Kayleigh’s face pressed into the pillow, drool soaking it, and Kelley recognised the signs. She drove harder.

Hours blurred into a haze of relentless fucking. By dawn, Kayleigh lay spent, body marked with rope burns and handprints, pussy and ass both raw with loving abuse. Kelley untied her gently, removing the gag to kiss her swollen lips. “I couldn’t wait anymore,” she whispered.

Kayleigh, voice hoarse, pulled her close. “I’d stopped hoping for this.”
