Brother Sister Incest: Stormy Night Forbidden 🔥

Feral Whispers in the Rain

Thunder rumbled outside the high-rise apartment window, shaking the glass like a predator’s growl. Rain lashed against the panes, turning the city lights into smeared halos. I, Jax, lounged on the worn leather couch, my black fur still damp from the dash home through the downpour. As a wolf anthro scraping by as a garage mechanic, nights like this were my favorite—cozy inside while the world outside raged. But tonight, the storm wasn’t the only thing stirring up trouble.

My sister Kira padded into the living room, her red fur glistening under the dim lamp light. She was a fox, sleek and sly, with those piercing green eyes that always seemed to see right through me. At twenty-two, she was chasing some art degree downtown, her paws forever stained with charcoal or paint. We shared this cramped two-bedroom place since our folks kicked us out last year—said we needed to “grow up.” Yeah, right. Growing up meant more freedom for the kind of games Kira and I had been playing since we hit puberty.

She shook out her tail, spraying droplets everywhere, and shot me a smirk. “Missed the bus again, furball? You reek like wet dog.”

I chuckled, low and rumbling, my ears flicking back. “Better than smelling like that cheap studio paint you drown yourself in, sis. Come here—let me dry you off proper.”

Her laugh was sharp, but she didn’t pull away when I tugged her onto my lap. The leather creaked under us, cool against my thighs. Kira’s body heat seeped through her thin tank top, her four perky tits pressing against my chest—foxes like her had that extra set, a genetic quirk that drove me wild. I nuzzled her neck, inhaling the mix of rain, her musky scent, and that faint floral shampoo she hoarded.

“Jax…” she murmured, but her paws were already clawing at my shirt, nails scraping fur. The storm outside picked up, wind howling like it approved.

Chapter 1: Storm’s Tease

Earlier that day, before the skies cracked open, I’d been elbow-deep in engine grease at the shop. My phone buzzed in my pocket—Kira, of course. “Stuck late at class. Bring home takeout? And something fun? 😏” The emoji made my sheath twitch under my work jeans. Fun meant her favorite toys, the ones we’d “borrowed” from a shady online shop catering to anthros with tastes like ours.

I fired back: “Only if you promise to model that new tail plug.” Her reply was a string of fire emojis, enough to make my shift drag on forever. By the time I clocked out, thunderheads were brewing, and I grabbed Thai food and a discreet bag from the adult store downtown. The rain hit as I jogged to the subway, soaking my fur, but the anticipation kept me warm.

Now, back in the apartment, Kira ground against me, her hips rolling in that deliberate way she knew got me hard. “You got it?” she whispered, nipping my ear.

“Patience, vixen.” I slid a paw under her shirt, cupping one of her lower breasts, thumb circling the nipple until it pebbled. She gasped, the sound mixing with the rain’s patter. Her fur was soft, like velvet over steel, and I could taste the salt on her skin as I licked a stripe up her neck.

She fumbled with my belt, paws eager. “Fuck patience. I need you now, big bro.” Her voice was husky, laced with that feisty edge that always made me want to pin her down.

I flipped us, her back hitting the couch cushions. The Thai food sat forgotten on the coffee table, steam rising like our building heat. I yanked her tank top over her head, exposing those glorious tits—two pairs, all perky and begging for attention. My muzzle dove in, sucking on one nipple while pinching another, her moans filling the room over the storm’s roar.

“Ah, Jax… yes, like that…” She arched, tail thrashing, knocking over a lamp. It clattered but didn’t break—our place was a mess of art supplies and tools anyway.

My cock strained against my jeans, the knot at the base already swelling. I ground it against her thigh, letting her feel the promise. “You want this wolf dick, Kira? Beg for it.”

She growled, playful defiance in her eyes. “Make me.”

Challenge accepted. I stripped her shorts off, revealing her slick folds, already glistening. The scent hit me—musky, aroused fox heat that made my head spin. I buried my muzzle there, tongue lapping broad strokes, tasting her sweetness mixed with the day’s sweat.

Her paws gripped my ears, pulling me closer. “Deeper… fuck, your tongue’s magic.”

I obliged, spearing inside her, while thunder boomed approval. She bucked, coming undone fast, her juices coating my chin.

Chapter 2: Echoes of Forbidden Paws

Our games weren’t new. I remembered the first time, years back in our parents’ old cabin upstate. Summer heat, no AC, just Kira and me sharing a room while Mom and Dad were out hunting. She’d snuck into my bed, whispering about how she’d overheard them rutting like beasts. “Show me, Jax,” she’d said, her paw on my sheath.

That night, under flickering firefly light through the window, I’d knotted her for the first time. Her cries had been muffled against my fur, but the bond formed—secret, intense, unbreakable. Now, in the city storm, those memories fueled me as I shed my clothes, my thick wolf cock springing free, red and throbbing.

Kira eyed it hungrily, licking her lips. “Gods, you’re huge. Come on, mount me.”

I positioned her on all fours, the couch groaning under us. Rain drummed relentlessly, masking her whines as I teased her entrance with my tip. “Tell me you need your brother’s knot, sis.”

“I need it… fuck me raw, Jax. Knot me deep.” Her tail lifted, exposing everything.

I thrust in, one smooth motion burying to the hilt. She yipped, walls clenching like a vice. The heat of her was scorching, wet sounds of flesh meeting flesh echoing with each pound. My paws gripped her hips, claws digging just enough to mark without breaking skin.

“Harder! Make it hurt so good,” she demanded, pushing back.

I obliged, slamming into her, my balls slapping her clit. The apartment smelled of sex now—sweat, fur, arousal—overpowering the rain’s fresh ozone. Her tits swayed, brushing the leather, and I reached around to grope them, twisting nipples until she howled.

Lightning flashed, illuminating her arched back, red fur slick with sweat. I felt my knot swelling, pressing against her entrance. “Gonna tie you, Kira. Fill you up.”

“Do it… breed me like the bitch I am.” Her words were crude, filthy, spurring me on.

With a final thrust, the knot popped in, locking us. I ground deep, her pussy milking me as I erupted, hot spurts painting her insides. She came too, shuddering, her scent peaking in ecstasy.

We collapsed, tied and panting, the storm our only witness. But I wasn’t done—far from it.

After a few minutes, the knot deflated enough for me to pull out, cum dripping from her. “Shower?” I suggested, voice rough.

She grinned, wicked. “Only if you wash me… everywhere.” 💋

Chapter 3: Steamy Depths

The bathroom was tiny, steam already fogging the mirror as hot water cascaded from the showerhead. Kira stepped in first, her fur darkening under the spray, rivulets tracing her curves. I followed, crowding her against the tiles—cool porcelain contrasting the heat.

“My turn to tease,” she purred, grabbing the soap and lathering my chest. Her paws roamed lower, stroking my semi-hard cock back to life. The suds smelled of lavender, mixing with our lingering musk.

I groaned, head tipping back as rain pounded the small window. “Careful, vixen, or I’ll bend you over right here.”

“Promises.” She dropped to her knees, water sluicing over us, and took me in her muzzle. Her tongue swirled, fox agility making it sinful—long laps along the underside, teasing the knot.

The taste of salt and soap filled my mouth as I kissed her deeply when she stood, but she spun away, bracing against the wall. “From behind. Now.”

I didn’t need telling twice. My paws spread her cheeks, thumb circling her tight rear entrance—a new territory we’d explored once before, in a motel on a road trip. “You sure?”

“Fuck yes. Lube’s in the drawer.” She glanced back, eyes smoldering.

I slicked up, the gel cool against the steam. Easing in slow, her ass gripped me like fire—tight, unyielding at first, then yielding with a pop. She moaned, loud over the water’s rush, “Oh gods, Jax… stretch me.”

I built rhythm, paws on her waist, the slap of wet fur echoing. Her tail wrapped my leg, pulling me deeper. Sensory overload: steam in my lungs, her cries in my ears, the slick glide of her heat around me.

“Cum in my ass, bro. Mark me.” Her voice broke, body trembling.

I did, roaring as I flooded her, knot barely fitting but pressing insistently. She fingered her clit, chasing her peak, and we came together, water washing away the evidence but not the thrill.

Toweling off later, she nuzzled me. “That was… intense. But the night’s young.”

I smirked. “Bedroom. Now.” 🔥

Chapter 4: Midnight Knots

Our bedroom was a sanctuary of chaos—Kira’s sketches pinned to walls, my tool belts draped over chairs. The bed dominated, king-sized for “comfort,” but really for nights like this. Moonlight pierced the clouds now, casting silvery glows on her red fur as she sprawled naked, legs spread invitingly.

“Come claim me,” she taunted, paws trailing her body, dipping into her still-slick folds.

I prowled over, a wolf on the hunt. “You’re mine tonight, sis. All holes, all night.”

She shivered, anticipation in her whine. I kissed her slow, tongues tangling—taste of mint from her gum, mixed with our shared flavors. My paws explored: squeezing her thighs, the firm globes of her ass, teasing those extra tits until she begged.

“Please… fuck my mouth first.”

I straddled her chest, cock sliding between her upper breasts, then lower set, the sensation decadent—soft furred pillows enveloping me. She craned her neck, sucking the tip, paws pressing her tits tighter.

“Good girl,” I growled, thrusting gently. Her saliva dripped, warm and wet, scent of arousal thickening the air.

Pulling back, I shifted down, entering her pussy again—easy glide, still stretched from before. Missionary this time, intimate, my weight pinning her. Eyes locked, breaths mingling.

“I love how you fill me,” she whispered, legs wrapping my waist. “Like we were made for this.”

I nipped her shoulder, thrusts deepening. “Incestuous wolves and foxes… society’s dirty secret.” The words hung, crude and true, heightening everything.

She clawed my back, drawing faint lines. “Harder—make me scream.”

The bedframe banged the wall, rhythm matching the fading storm. Her orgasm hit like lightning, pussy spasming, pulling my knot in. I followed, pumping seed deep, our howls blending.

But we weren’t sated. As the knot held, I rolled us, her on top. “Ride me till dawn.”

She did, hips grinding, tits bouncing hypnotically. Sweat beaded on her fur, tasting salty as I licked her neck. Hours blurred—positions shifting: her bent over the dresser, mirror reflecting our feral faces; against the window, city lights witnessing; even on the floor, carpet burning knees.

Each climax built on the last, bodies slick, scents overwhelming—cum, sweat, fur. Dialogues turned filthier: “Your knot’s ruining me for anyone else.” “Good—only my sister’s cunt gets this.”

Chapter 5: Dawn’s Reckoning

Sunrise crept in, painting the room gold. We lay tangled, exhausted but glowing. Kira’s head on my chest, paw tracing my abs. “Think we’ll ever stop this?” she murmured, voice sleepy.

I chuckled, nuzzling her ears. “Why would we? It’s us against the world.”

She lifted her head, green eyes serious for once. “But if anyone found out… anthro society frowns on siblings knotting.”

“Let ’em. Our bond’s deeper than blood—it’s fire.” I kissed her, slow and possessive.

Her paw wandered south, finding me stirring again. “One more? For luck.”

Groaning, I flipped her onto her belly. “Insatiable vixen.”

Entering her from behind, lazy thrusts building to fervor. The morning light highlighted every curve, every quiver. Her moans were softer now, intimate whispers: “Love you, Jax… don’t stop.”

“Never,” I promised, knotting her once more, spilling with a final, shuddering release.

As we untangled, the city awoke outside—horns blaring, life resuming. But in our den, the storm’s passion lingered, a secret flame ready to ignite again. Kira dressed for class, stealing a kiss. “Tonight? Same time.”

“Always.” I watched her go, tail wagging, already craving the next downpour. 💋

The door clicked shut, leaving me in the quiet aftermath. Our lives intertwined like vines—wild, untamed, eternally entwined in forbidden ecstasy. No regrets, just raw, unfiltered desire pulsing through our veins.
