Big Bro Caught Me Fucking The Dalmatian

Caught by her big brother with the family Dalmatian’s tongue deep in her pussy, Rosalin’s shame turns to filthy bliss as Ryan joins in, watching her get stuffed

The house settled into its nightly rhythm around nine. Mom’s footsteps creaked up the stairs, followed by the familiar click of her bedroom door. Dad’s low voice rumbled through the floorboards, then silence. Downstairs, I stacked the last dinner plate into the dishwasher, the clatter loud in the quiet kitchen. Ryan leaned against the counter, still in his work shirt, the grease stains stark under the fluorescent light. He watched me. He’d been watching me all night. My hand brushed his when I passed him a glass for water. His fingers lingered on mine for a half-second too long. I didn’t pull away.

“Long day?” he asked, his voice casual.

“The usual. Mrs. Jones wanted me to recommend books for her book club that ‘weren’t too depressing.’ I sent her home with a romance and a thriller.”

He laughed, a low sound that vibrated in my chest. “Survival of the fittest.”

Kane’s tags jingled as he padded into the kitchen, his nails clicking on the linoleum. He nudged my hand with his wet nose, then sat, his spotted ears perked. I scratched behind them, his head leaning into my palm. Ryan’s gaze followed the movement, then returned to my face. The air felt thick, heavy with unspoken things. It had been like this for weeks, ever since the couch. Ever since his hands were under my shirt and my name was a broken sound in his mouth before we both scrambled away like we’d been burned.

“You heading up?” Ryan asked, pushing off the counter. He was close now. I could smell the faint scent of motor oil and his deodorant, something clean and warm underneath.

“Soon,” I said, my voice softer than I meant. Kane whined softly, nudging my leg again. I knew what he wanted. What I wanted.

Ryan’s eyes flickered down to Kane, then back to me. He didn’t say anything, but a muscle jumped in his jaw. He gave a short, tight nod and turned toward the hallway. “Night, Ro.”

“Night.”

I waited until I heard his bedroom door click shut. I waited another ten minutes, just standing in the quiet kitchen, listening to the hum of the refrigerator. My heart was beating a little too fast. Kane pressed against my side, a solid, warm weight. I locked the back door, double-checked the front, then started up the stairs. Each step was a decision. Each creak of the floorboards under my feet was a promise I was making to myself.

My room was just down the hall from his. I didn’t look at his door as I passed it. Inside, I locked my own and leaned against it, closing my eyes. Kane circled his bed once, then settled with a soft huff. I flipped the small switch on my bedside lamp, casting a warm, dim light across the rumpled duvet. The streetlamp outside threw a pattern of shadows on the wall. I pulled my sleep shorts and my underwear down in one motion, letting them pool on the floor. The air was cool on my skin. I sat on the edge of the bed, thighs parted, and patted the space between them.

“Here, boy.”

Kane was up in an instant, his tail giving a single thump against the comforter. He trotted over and lowered his head, his dark eyes looking up at me for a moment before his tongue, warm and impossibly wide, lapped against me. A shaky sigh escaped my lips. I leaned back on my elbows, letting my head fall against the pillows. It was always like this at first. A slow, deliberate rhythm. Broad, wet strokes from my entrance all the way up to my clit. The texture was different from anything else, rough and insistent, sending sparks up my spine with every pass. My hips began to move, a slow, unconscious roll against his mouth. One hand found its way into the short fur of his ruff, just holding him there, a silent encouragement.

I sucked in a breath. A soft moan, barely audible, filled the quiet room. I was getting close, the heat coiling tight in my belly. My other hand gripped the duvet, my knuckles white. And then... the floorboard. Right outside my door. A loud, decisive creak.

I froze. My eyes flew open. I shoved Kane’s head away, scrambling for the blanket, yanking it over my lap with a gasp that was half panic, half sudden, sharp loss. My heart hammered against my ribs, a wild drumbeat in the silence. The doorknob turned.

Ryan stood there, silhouetted in the hallway light. He wore only his boxers, his chest bare. His expression, first soft with concern, shifted as his eyes adjusted. He took in the flush on my cheeks, my heaving chest, Kane sitting patiently at the foot of the bed.

“What the fuck are you doing?” he asked. His voice was low.

“Nothing,” I said, the word a useless puff of air. “Go away.”

He didn’t. He stepped inside, closing the door with a soft click that sealed us in. He crossed the room in three long strides. Before I could react, his hand was on the blanket. He pulled it down. Cool air hit my exposed, wet skin, and I shivered. His eyes darkened, his gaze falling right between my legs. His hand moved to his own crotch, rubbing the hard outline there, his thumb brushing a damp spot at the head of his cock.

“You were letting him lick your pussy,” he said. It wasn’t an accusation. It was a fact, delivered in a rough voice that made my inner muscles clench. “I can see how wet you are.”

My face was on fire. Shame and something else, something hot and shameful, warred inside me. “Ryan, please...”

He kept stroking himself through the fabric, slow, deliberate. “Carry on.” His eyes met mine. “I want to watch.”

I stared at him. The part of me that wanted to disappear, to sink through the mattress and never be seen again, screamed. But another part, a deeper, hungrier part, was looking at the thick shape of his cock, at the obvious wet spot of precum, at the raw want on his face.

"You want to watch?" The words were a whisper.

A muscle in his jaw jumped. "Yeah."

My gaze flickered to Kane, sitting so calmly, waiting for my command. Then back to Ryan. The memory of the couch surfaced... his hands on my hips, his mouth on mine, the frantic, breathless need we’d both fled from. It all felt connected. This felt like the only way forward. Through it. Not around.

Slowly, I nodded.

I let my thighs fall open again. Kane didn’t need a second invitation. He moved forward, his head dipping low, and his tongue was back on me. That first warm, wet drag made me gasp, my head falling back against the pillows. My eyes fluttered shut. This was my secret, my shame, my one solace. And now he was seeing it all.

The sound of fabric rustling made my eyes snap open. Ryan was pushing his boxers down, kicking them aside. His cock sprang free, thick and hard, the flushed head already glistening. He spat into his palm and wrapped his hand around himself, stroking slowly as his gaze stayed locked on me, on Kane’s mouth on my pussy.

“Fuck,” he muttered. “That is so messed up, but hot as fuck.”

He stepped closer to the side of the bed, so close his knees brushed the mattress. His cock was right there, a heavy, flushed curve, the slit beading with more precum.

"I want you to suck it." His voice was a raw whisper. "Open your mouth for me."

I looked from his cock to his face, then to Kane, whose tongue was working with its familiar, steady rhythm. A tremor went through me. It was wrong. All of it was wrong. And I wanted it more than I'd ever wanted anything. I parted my lips.

Ryan guided the head to my mouth, his other hand coming up to cup the back of my head. The tip felt hot against my lips, tasting faintly salty and clean. He pushed in, just a little, just past my teeth, and my tongue flicked against the underside of his crown. A low groan rumbled in his chest.

"Fuck... Rosalin..."

At the same time, Kane’s tongue pressed more firmly against my clit, a focused, swirling pressure that made my toes curl. The dual sensation of Ryan’s cock filling my mouth, and Kane’s tongue lapping at me was overwhelming. A moan vibrated in my throat, and Ryan’s fingers tightened in my hair.

"Yeah," he breathed. "Just like that."

He started to rock his hips, a slow, shallow rhythm, feeding me more of his length with each thrust. I hollowed my cheeks, sucking him in, my hand coming up to wrap around the base, stroking in time with my mouth. He was thick, stretching my lips, the heat of him a solid weight on my tongue. The sounds were obscene now... the wet, rhythmic lapping from Kane, the soft, slick sounds of my mouth on Ryan’s cock, our mingled breaths.

Ryan watched my face, his eyes dark and intense. "Look at you," he said, his voice rough. "Taking it so good while he licks your pretty pussy."

A fresh wave of heat washed over me, and my hips rolled up to meet Kane’s tongue. The praise, the dirty talk, it was all fanning the fire inside me, building the pressure in my core higher and higher. My free hand gripped the duvet, the fabric bunched in my fist.

My eyes fluttered shut, focusing on the sensations. The rough texture of Kane's tongue against my sensitive flesh, the smooth, hot skin of Ryan's cock sliding in and out of my mouth, the way his grip on my hair was both firm and gentle.

"Look at me," Ryan commanded softly.

I forced my eyes open, lifting my gaze to his. The intensity in his eyes made my stomach clench. He looked like he was devouring me with his eyes, like he couldn't get enough.

"You ever let him fuck you?" The question was so unexpected, so shocking, that I almost choked. My eyes widened, and I instinctively tried to pull back.

Ryan's grip on my hair tightened, keeping me in place. "No, no, don't stop sucking," he said, his voice firm. "Just answer the question. Have you ever let him mount you?"

I shook my head as much as I could with his cock still in my mouth, my heart pounding with a mixture of fear, shame, and a disturbing thrill at his question. The thought had crossed my mind, late at night in the dark, but I'd never... I couldn't...

"No," I managed to gasp around him, a tear escaping and tracing a path down my cheek. "Never."

"Well," he breathed, his thumb coming up to wipe away the tear. "Maybe we can change that. Do you want to feel his dick in you, sis?"

I didn't know how to answer. The question hung between us, charged and dangerous. Kane's tongue was still working me relentlessly, building me toward orgasm, and Ryan's cock was still filling my mouth, but now there was this new element, this new boundary being tested.

Ryan seemed to sense my hesitation. "I'll help you," he said softly, his hips stilling. "I'll make sure it'll be fine. If you want it."

He pulled back slightly, just enough that I could take a full breath. "But first, I need you to cum for me. Cum on his tongue, just like you were before I walked in. Show me how you like it."

His words sent a jolt through me, and my hips bucked involuntarily. Kane took it as an invitation, his lapping growing more insistent, his tongue pressing harder, flicking faster against my clit.

"That's it," Ryan encouraged, his hand stroking my hair now, the motion gentle and reassuring. "You're so close, I can feel it. Your whole body's trembling."

He was right. I was trembling. The coil in my belly was impossibly tight, threatening to snap at any moment. I could feel the pleasure building, a tidal wave of sensation threatening to pull me under.

"Look at me while you cum," Ryan commanded, his voice low and firm. "I want to see your face."

I forced my eyes open, meeting his intense gaze. The connection was electric, and it sent me over the edge. My back arched off the bed, a strangled cry tearing from my throat as my orgasm crashed through me. Waves of pleasure washed over me, starting from where Kane's tongue was still lapping at me and radiating outward, making my toes curl and my fingers clench in the duvet. My whole body shook, and I could feel my pussy clenching around nothing, desperate for more.

Ryan's fingers tightened in my hair. "That's it, baby. That's so fucking hot."

Kane didn't stop. He kept licking, his tongue dragging through my release, his movements slow and deliberate now, drawing out my pleasure until I was a trembling, whimpering mess. My hips jerked with each pass of his tongue, overstimulated but unwilling to make him stop.

Ryan watched me, his eyes dark with lust. He was still hard, his cock flushed and demanding. "You're beautiful when you cum," he said, his voice thick with emotion.

He leaned down, his lips brushing my ear. "I need to be inside you."

A shiver went through me, a fresh wave of heat pooling in my belly. I wanted it. God, I wanted it.

"Please," I begged, my voice hoarse.

He didn't need to be told twice. He gently pushed me back against the pillows, his body covering mine. Kane, sensing the shift in dynamics, moved to the foot of the bed, lying down with his head on his paws, his eyes watchful.

Ryan positioned himself between my legs, his cock nudging at my entrance. He was hot and hard, and the anticipation was driving me wild.

"You're so wet," he murmured, his voice rough with desire. "So ready for me."

He pushed in, just the tip, and I gasped at the stretch. He was thicker than I'd expected, the head of his cock a delicious pressure against my inner walls. He paused, giving me a moment to adjust, his eyes searching mine.

"You okay?" he asked, his voice soft with concern.

I nodded, my breath hitching. "Yeah. Just... go slow."

He smiled, a gentle, reassuring smile that did funny things to my heart. "Of course."

He pushed in a little further, and I moaned, my back arching off the bed. He filled me completely, stretching me in a way that was both painful and intensely pleasurable. He paused again, his body trembling with the effort of holding back.

"More," I gasped, my hands flying to his shoulders, my nails digging into his skin. "Please, Ryan, more."

He needed no further encouragement. He slid home in one smooth, deep thrust, burying himself to the hilt. I cried out, my body arching to meet his. He felt incredible, a perfect, solid weight inside me, hitting a spot that made my toes curl.

"Fuck," he groaned, his forehead resting against mine. "You feel so good. So tight and wet for me."

He started to move, a slow, deliberate rhythm that was driving me insane. Each thrust was a deep, powerful stroke that sent waves of pleasure coursing through my body. I wrapped my legs around his waist, pulling him deeper, needing more.

"Faster," I panted, my hips rising to meet his. "Please, faster."

He complied, his movements becoming more frantic, more desperate. The sound of our bodies slapping together, mixed with our ragged breaths and moans, filled the room. He was hitting just the right spot, over and over, and I could feel another orgasm building, a slow, insistent heat coiling in my belly.

"Ryan," I gasped, my fingers tangled in his hair. "Ryan, I'm close."

He groaned, his pace increasing even more. "Me too, Ro. Me too."

He reached down between us, his fingers finding my clit. He rubbed it in tight, fast circles, and that was all it took.

"Oh fuck, I'm cumming. I'm cumming, Ry..!"

I came with a strangled cry, my body convulsing around him, my vision whiting out with pleasure. He followed me over the edge a moment later, his body shuddering as he spilled inside me, his cock pulsing with his release.

We collapsed against each other, a sweaty, breathless tangle of limbs. For a long moment, we just lay there, our hearts hammering against each other's chests, the sound of our breathing the only noise in the room.

Kane, who had been a silent, watchful presence at the foot of the bed, whined softly, breaking the spell.

Ryan rolled off me, his arm still draped over my waist, and looked at Kane. "It's okay, boy," he said, his voice hoarse. "Just give us a minute."

Kane whined again, his tail giving a hopeful thump against the mattress.

Ryan looked at me, a question in his eyes. "You still want to?"

I did. The thought was terrifying, but it was also exhilarating, a taboo thrill that I couldn't resist. I nodded, my heart hammering with a mixture of fear and anticipation.

Ryan smiled, a slow smile that made my stomach clench. "Get on your hands and knees, then."

I scrambled to obey, my body trembling with a combination of exhaustion and renewed desire. I positioned myself in the center of the bed, my ass in the air, my face buried in the pillows. I could feel Ryan's eyes on me, his gaze a physical caress that made my skin tingle.

"You're so beautiful," he said, his voice soft with wonder. "So fucking beautiful."

He reached out and ran a hand down my spine, his touch gentle and possessive. "Are you ready?"

I took a deep breath, trying to steady myself. "Yeah," I said, my voice muffled by the pillows. "I'm ready."

He patted my ass, a light, playful tap. "Good girl."

He got off the bed, and I heard him walk over to Kane. There was a low murmur of voices, too quiet for me to make out the words, then the sound of Kane's nails on the floorboards as he approached the bed.

I felt the mattress dip as Kane jumped up, his weight a familiar, comforting presence behind me. He sniffed at my pussy, his breath hot against my sensitive skin, and I couldn't help but flinch.

"Easy, boy," Ryan said, his voice calm and reassuring. "Easy now."

I felt Kane's nose press against my pussy, a tentative exploration, then the first hot, wet swipe of his tongue. A soft moan escaped my lips, and I arched my back, presenting myself to him more fully.

"That's it," Ryan encouraged, his voice close to my ear. "Let him taste you."

Kane's lapping grew more confident, his tongue delving deeper, the rough texture sending sparks of pleasure shooting up my spine. I was already sensitive from my previous orgasms, and his ministrations were almost too much, but I didn't want him to stop. I pushed back against his mouth, silently demanding more.

Ryan watched us, his eyes dark with lust. He was hard again, his cock standing at attention, a bead of precum glistening at the tip. He wrapped a hand around himself, stroking slowly, his gaze never leaving us.

"You like that, don't you?" he asked, his voice thick with desire. "You like his tongue on your pussy."

I could only moan in response, my hips rolling in time with Kane's lapping. I was getting close again, the familiar heat coiling in my belly, but before I could reach the peak, Ryan spoke again.

"Kane, up."

Kane whined, but he obeyed, pulling away and circling me once before stopping behind me. His weight shifted on the bed, and I felt the tickle of his fur against the backs of my thighs. My heart pounded in my chest, a frantic drumbeat of fear and anticipation.

"It's okay," Ryan soothed, his hand stroking my lower back, his touch warm and reassuring. "I'm right here. I won't let anything happen to you."

He knelt in front of me, his cock right in my face. "Suck me," he commanded. "Let him in while you're sucking me."

I opened my mouth, taking him in, the taste of him familiar and comforting. As I wrapped my lips around his cock, I felt Kane's front paws wrap around my waist, his claws digging into my skin just enough to ground me. I tensed, my whole body going rigid.

"Relax," Ryan urged, his hand cupping the back of my head. "Just let it happen."

I took a deep breath, forcing myself to relax my muscles. I felt Kane shift again, his haunches tensing as he found his position. And then, I felt it. The hot, hard length of his cock nudging at my entrance. He was bigger than I'd imagined, the head of his dick a pointed, insistent pressure against my pussy lips.

"Push back," Ryan coached, his voice a low, steady murmur. "Just a little."

I did, arching my back, and the head of Kane's cock slipped inside me. It was a sharp, sudden stretch, a burning sensation that made me gasp around Ryan's dick.

"Easy, boy," Ryan said, his hand still stroking my hair. "Easy."

Kane whined, his body trembling with the effort of holding still. I could feel his need, his instinct to drive into me, to claim me. And then, with a powerful thrust of his hips, he was inside me, burying himself to the hilt in one smooth, deep stroke.

I cried out, the sound muffled by Ryan's cock in my mouth. The stretch was intense, a mix of pleasure and pain that left me breathless. Kane's dick was different... hotter, harder, with a distinct bulge at the base that was already stretching me wider.

"Fuck," Ryan groaned, his eyes fixed on where we were joined. "He's all the way in. You're taking all of him."

Kane started to move, his thrusts fast and frantic, a primal, animalistic rhythm that was nothing like Ryan's measured, human pace. Each thrust was a deep, powerful stroke that sent a jolt of pleasure through me, his hot length hitting a spot deep inside me that I didn't even know existed.

I lost all track of time, all sense of self. There was only the feeling of Kane's dick in my pussy, Ryan's cock in my mouth, the sounds of our combined pleasure filling the room. I was a vessel for their desire, a willing participant in this taboo, three-way dance.

And then, I felt it. A growing pressure at my entrance, a stretching sensation that was both alarming and intensely arousing. Kane's knot was swelling, locking us together in a way that was both terrifying and exhilarating.

"He's knotting you," Ryan breathed, his voice thick with awe. "He's fucking knotting you, sis."

I could only moan in response, my body convulsing around Kane's dick as another orgasm ripped through me. The added pressure of his knot against my G-spot was too much, and I came with a strangled cry, my body arching off the bed.

Kane let out a low growl, his body shuddering as he found his own release, hot jets of his cum flooding my insides. The feeling of being so completely filled, so utterly claimed, sent me over the edge again, my body trembling with the force of my orgasm.

We stayed locked together for what felt like an eternity, Kane's weight a comforting presence on my back, his knot a constant, throbbing pressure inside me. Ryan watched us, his expression a mix of lust, concern, and something else, something deeper, more tender.

"You okay?" he asked, his voice soft.

I could only nod, my body too wrung out to form words. I was a mess of sweat, cum, and conflicting emotions, but I'd never felt more alive.

Kane's knot eventually subsided, and with a final, reluctant thrust, he pulled out, a flood of our combined fluids gushing out of me. He licked me clean one last time, his tongue a gentle, soothing caress, then jumped off the bed, his tail giving a hopeful thump against the floorboards.

Ryan was there in an instant, his arms wrapping around me, pulling me into his embrace. "You did so good," he murmured, his lips brushing my forehead. "You were so brave."

I collapsed against him, my body too weak to hold me up. He laid me down on the bed, his touch gentle, his eyes full of a tenderness that made my heart ache. He cleaned me up with a warm, wet cloth, his movements careful and deliberate, then climbed into bed beside me, pulling the covers over us both.

Ryan had his fingers wrapped around his shafts, milking his cock. He grunted and I felt his cum blast into my mouth, thick and hot and salty. It hit my tongue, the back of my throat. I swallowed, once, twice, my throat working, then a third time, but some still escaped, dripping down my chin and onto my breasts. He kept coming, more than I expected, and the taste of him filled my senses. I kept sucking gently, my tongue swirling around the sensitive head, drawing out the last pulses of his orgasm.

When he was finally spent, he pulled back, his cock softening in my hand. I wiped my chin with the back of my hand, smearing his cum across my skin. He was looking down at me, his expression unreadable, his chest heaving.

"That was..." he started, then trailed off, as if he couldn't find the words.

I knew what he meant. It was... a lot. Too much. Not enough. Everything.

He lay down beside me, his arm wrapping around my waist, pulling me close. I could feel the steady beat of his heart against my back, a grounding, reassuring rhythm. Kane hopped up on the bed and curled up at our feet, his warm, solid weight a comforting presence.

We lay in silence for a long time, the only sounds our breathing and the soft snores from Kane. The room was dark now, the only light the faint glow from the streetlamp outside. I could feel Ryan's cum drying on my skin, a sticky, uncomfortable reminder of what we'd done.

"Are you okay?" he asked, his voice a low murmur against my ear.

I took a deep breath, the air thick with the scent of sex and sweat. "I don't know," I admitted, my voice barely a whisper. "Are you?"

He was quiet for a moment, his thumb tracing circles on my hip. "I'm... overwhelmed," he said finally. "But not in a bad way. It's just... a lot to process."

I turned in his arms to face him, my hand resting on his chest, over his heart. "I never thought... I mean, I've thought about it, obviously, but I never thought it would actually happen."

He smiled, a small, wry smile that didn't quite reach his eyes. "Me neither. Not the dog part, anyway."

I flinched, a sharp pang of guilt twisting in my gut. "Sorry about that."

He shook his head, his hand coming up to cup my cheek, his thumb brushing away a stray tear I hadn't realized was falling. "Fuck no. Don't be, Ro." He was close, his breath warm on my face. "It was the hottest thing I've ever seen."

A fresh wave of heat washed over me, and I leaned in, my lips seeking his. He met me halfway, the kiss slow and tender, a stark contrast to the frantic, desperate energy from before. It was a kiss of understanding, of acceptance, of a shared, secret bond that was no longer a secret.

When we pulled apart, he was looking at me with an expression that made my heart ache. It was a mix of lust, concern, and something else, something deeper, more tender. "We're going to have to talk about this," he said softly.

"I know," I agreed, my voice thick with emotion. "But not now. Please, not now."

He nodded, his forehead resting against mine. "Okay. Not now."

He kissed me again, a soft, lingering kiss that promised more conversations, more revelations, but for now, we just needed this. Just this moment of quiet understanding in the aftermath of our shared transgression.

We lay there for a while, wrapped in each other's arms, the silence a comfortable, companionable presence. Kane's soft snores were a steady, rhythmic sound in the background, a reminder of the strange, new reality we had created together.
