Sunlight poured through the open windows, painting golden stripes across their naked bodies.
Laura woke first.
She rolled onto her side and just watched Alex sleep: messy hair, lips parted, the faint bruises she'd left on his neck glowing in the morning light. Her fingers traced his jaw, his cheekbones, then ruffled his hair like he was a kid.
He didn't stir.
Her gaze drifted lower. Morning wood.
His cock stood straight up, thick and proud, curving slightly toward his stomach like it was reaching for her.
Laura's lips curled into a wicked smirk.
She slipped out of bed, bare feet silent on the hardwood, opened the nightstand drawer, and pulled out a condom. Back on the bed, she straddled his thighs, carefully rolled it down his length (he still didn't wake), then lined him up and sank down in one slow, perfect drop.
Alex's eyes snapped open on a sharp inhale.
Laura didn't give him time to speak.
She started riding him hard: hips slamming, head thrown back, breasts bouncing so violently they slapped against her ribs.
Alex's hands flew to her hips, fingers digging in. "What....no good morning?"
Laura didn't slow, just ground down harder. "No… only… ahh… good… mmm… fucking!"
He groaned, thrusting up to meet her. "How the fuck are you this horny, sister?"
"You… mm… are the one… ahh… sleeping beside me… with this huge delicious dick!"
"Fuck, Laura!"
"Fuck you, brother!"
Alex sat up, grabbed her ass with both hands, and started slamming her down onto him while thrusting up at the same time. The bedframe cracked against the wall.
Laura's moans turned into full screams: "Ahh… brother… fuck your sister's pussy!"
Alex growled, half-laughing, half-desperate: "Hey....can you not say brother and sister? Sounds wrong....we're not...."
"I would still fuck you if you were my real brother!"
"That's incest, Laura!"
"Like it's very different now, fucker! Shut up and let me fuck my brother!"
She crushed his head to her chest, arms locked around his neck, his face buried between her bouncing breasts.
The intensity went nuclear: Skin slapping skin, Headboard splintering, Both of them screaming filth and I love yous in the same breath
They came together: Laura first, body seizing, nails carving into his shoulders; Alex right after, roaring into her chest, hips jerking violently.
They collapsed sideways, still joined, panting like they'd run a marathon.
Hours later: noon.
They lay tangled in the wrecked sheets, sunlight hot on their skin.
Laura traced lazy circles on his chest. "Brother… let's go to the lake."
Alex laughed, voice hoarse. "That boathouse is ancient. We have a perfectly good shower upstairs."
Laura propped herself on one elbow, eyes gleaming. "Don't be a pussy, brother. We came to a lake house and haven't fucked in the actual lake yet. It'll be an insult to the lake."
He raised an eyebrow. "You can swim, right?"
She grinned, already rolling out of bed, naked and shameless. "Obviously. Now get up. My brother's taking me swimming."
Alex groaned, but he was already hard again just watching her walk away.
Laura walked ahead of him, completely naked, hips swaying like a promise. Every step made her bare ass move in slow, hypnotic circles.
Alex followed a few paces behind, cock already hard again, eyes locked on the perfect curve of her cheeks and the faint red handprints he'd left that morning.
The boathouse appeared through the pines: Weathered cedar, half-swallowed by vines. A narrow walkway leading to a small covered dock Old wooden stairs descending straight into the dark, mirror-calm lake. Sunlight slanting through gaps in the planks, painting gold stripes across the water.
They stepped onto the creaking dock.
The air smelled like pine, lake water, and sex.
Laura dipped a toe, shivered dramatically. "It's a bit cold."
Alex smirked. "Yeah."
She turned, water lapping at her ankles, eyes dark and wicked. "Wanna make it hot?"
That was all the warning he needed.
He grabbed a fistful of her hair, yanked her head back hard, exposing the long line of her throat. Laura let out a throaty moan that echoed across the lake.
Alex's voice was pure danger against her ear: "How about I fuck you until you're numb, little sister?"
He didn't wait for an answer.
He slammed her front-first into the rough cedar wall. One hand still fisted in her hair, the other spreading her thighs. He drove into her in one brutal thrust. Laura screamed, palms slapping the wood, back arching. He fucked her standing: hips pistoning, balls slapping her clit, water splashing around their legs with every violent stroke.
Her breasts bounced wildly, nipples scraping cedar. "Ahh....Alex....too much....!"
He spun her, bent her over the splintered railing so her upper body hung over the lake. Took her from behind again: spanking her ass red between thrusts, pulling her hair like reins. Every slap echoed across the water.
Laura's screams turned hoarse: "Harder....please....brother....!"
He dragged her down the stairs until they were waist-deep. Locked her into a full nelson: arms under her knees, hands behind her neck: and lifted her completely off the lake bottom. Used gravity and raw strength to impale her over and over. Water exploded around them with every drop.
Her tits jiggled violently; eyes rolled white; mouth open in a constant scream.
He threw her onto the lower stairs, half-submerged, water lapping at her hips. Folded her in half: ankles by her ears: and destroyed her. Each thrust sent waves rippling across the lake. Spanked her ass between strokes until it glowed red.
Laura was sobbing, begging, coming so hard her whole body seized: "I can't....Alex....please....ahh....!"
He lifted her, slammed her back against a thick wooden beam under the boathouse. Her legs locked around his waist, arms around his neck. He fucked her standing, water churning white around them, biting her neck hard enough to leave teeth marks.
Her breasts crushed against his chest, bouncing with every brutal thrust.
He flipped her onto the small floating platform tied to the boathouse. Prone-bone in the open sun: one hand pressing her cheek to the warm wood, the other spanking her relentlessly.
Her screams turned into broken whimpers.
He sits on the edge of the dock, pulls her back to his chest, impales her reverse-cowgirl style, then stands: holding her entire weight while thrusting upward.
Her tits bounce insanely, head thrown back against his shoulder, screaming his name to the sky.
Flips her upside-down, shoulders on the wood, legs straight up in the air. He squats over her and drives straight down: deepest angle possible.
Laura's eyes are permanently rolled back, body trembling, squirting into the lake with every orgasm.
Alex didn't stop.
Laura was barely conscious: Limbs limp, Voice gone. Only tiny shattered gasps escaping her lips. Tears and lake water mixing on her cheeks.
Alex came with a primal roar, slamming into her one last time, holding deep while the condom filled.
He pulled out slowly, gathered her trembling, ruined body against his chest. Laura's head lolled against his shoulder, eyes fluttering, barely able to focus.
Alex kissed her damp forehead, voice low and possessive: "Hold on tight, dear sister.
Your brother just started loving you."
He carried her limp form back up the stairs, water dripping from both of them, leaving the boathouse rocking gently behind them.
Day 2 wasn't even halfway over and Laura was already beautifully, perfectly destroyed.
