Meet Sam: a young 9 year old puppy why just wants to hang out with his big bro on the one night they have alone! But his friends are over, and whilst they appear accommodating, the night quickly takes a dark turn...!

Warning: this story features a rather dark Rape.


It was a hot and humid summer evening, and Sam watched his parent's car pull out of the Driveway with his typical, 9 year old pout. His parents were going out for the evening: a 'date', they called it, and he wasn't pleased. He'd wanted to tag along! But they had shut down all hopes of that at the last minute, and he was left at home with his brother.

That wasn't necessarily a bad thing, of course: he loved his brother! Kevin was you standard angsty teenager, but Quinn saw through that bravado to see a kind heart and a loving family member. The husky cub slid off of his kneeling position on the windowsill to make his way towards the stairs. He peered up to see his brother, Kevin, looked sourly down at him, as if expecting Sam's shining face to come into view.

"What?" Kevin's expression darkened at Sam's wide grin as the cub slowly made his way up the stairs. Kevin had a phone in his hand and he quickly locked the screen, heading through into his small bedroom. Unsurprisingly, his brother followed.

"Nothin'," Sam sounded nonchalant in his response, but he was secretly bored. "Mom and Dad's gone. Whatcha wanna do?"

"What I want to do," Kevin began, turning towards his brother. "Is for you to scram."

Despite his brother's rather indifferent and perhaps annoyed dismissal, Sam didn't appeared swayed. Kevin was often cynical, and a little bit irritable around his younger brother, and Sam had come to expect it. But the cub briefly remembered the times the two would cuddle together a few years ago. That's what kept him going.

"Why?" Sam sported your typical 9 year old behaviour of being relatively obnoxious, even though his question was genuine. If it was just them two, then why did his brother want to sit on his own? His young mind couldn't comprehend it.

"I've got friends coming over, that's why. We're gonna sit in the hot tub. It's too damn warm." Kevin reached into his drawers and retrieved a loose pair of swimming shorts, as opposed to normal, 'macho' speedos. He tossed it onto his bed and peeled off his long-sleeve shirt to reveal his athletic chest and tucked-in stomach. He wasn't really much of an athlete, but most at his school would consider him 'moderately popular'.

He paused at his hands hovered above the button to his jeans, and he slowly turned to look at his brother, who still stood there. He furrowed his brow at what he could consider a 'shit-eating grin', but Sam didn't budge.

"Scram," He repeated, pointing towards the door, almost as if he was treating him like a dog. "I need to change."

"But I wanna hang out." Sam countered with a wide smile, not realising the lewd connotations of watching his brother undress. Kevin was about to argue until he realised his Brother wasn't going to budge even if he tried. With an exasperated sigh, he unbuttoned his jeans and tugged them down.

Sam watched with a lingering curiosity. He felt a tingling along his skin as his eyes quickly glanced down to Kevin's boxer shorts, seeing the thin outline of the sheath hidden beneath the fabric. It wasn't a bad feeling, but nor was it good. It was simply just an odd sensation that he didn't appear to deny. The husky cub was only 9, thinking nothing of the actual sexual connotations that came to look at his brother's privates, so he simply looked out of pure curiosity. Was it wrong to want to see his brother's sheath? Possibly, but he didn't know that.

Kevin chose to not look Sam in the eye and instead fixated his gaze on the swimming shorts on his bed as he undressed. He kicked himself out of his jeans and tugged his boxers down, slipping the waistband over the plump sheath and letting them fall to his ankles. He was about an impressive at a 17 year old could be: his sheath was relatively large, and his balls were a normal size. He briefly adjusted himself with his hand as he reached for his shorts.

There was something uncomfortable about changing in front of his brother. Something that made him tingle. He chose to ignore it as he slipped on his shorts, and heard a brisk knock on the door downstairs. Both of their heads turned towards the door, and Kevin quickly walked past his brother before Sam could race down to answer it. He made his way to the stairs and heard the soft patter of his brother following behind him.

"You. Stay here." He quickly pointed to Sam, who stopped in his tracks and clamped his mouth shut, ears alert. He did as he was told as Kevin made his way down the stairs. A sour expression creeped across Sam's face as he sat on the top step, looking down towards the hallway below.

Sam heard the brief din of laughter amongst three friends, and he watched as a the trio of bodies immediately made their way past the stairs towards the back patio door. He could hear the door sliding open and took it as his cue to quickly make his way downstairs, before anyone could spot him. If he wasn't going to join in, he at least wanted a snack.

He landed on the final step and peered around the banister to stare down the hallway, which was a straight, direct beeline towards the back door. All along the hallway were clothes of varying sizes strewn all over the place. They must have been Kevin's friends getting undressed on the way.

He slowly tip-toed across the hallway towards the kitchen, where he could hear Kevin and his friends talking. He reached up to grab a biscuit or two at he listened.

"So what, you're parents are out on a date?" Sam heard a relatively gruff voice make itself known. "Sounds like their marriage is a shame. No offence."

"I just know they're assholes." Sam heard Kevin mutter, and the pup put a hand over his mouth. His parents were good people! But, Sam wouldn't scold him. He'd probably just tell on him instead.

"I bet they're gonna bone when they get back. You'll hear the moans for miles." Sam heard a small, almost cocky voice, and there was a few chortles of laughter in response.

"Shut up." Sam heard Kevin say, and the pup peered around to see them all lounging in the hot tub. Sam finally recognised the two friends: one of them was a Bear called Mike, and the other was a rabbit named Kyle. Sam remembered they were old friends of Kevin and he hung out with them on a regular basis.

Sam thought he could go and ask to hang out, but he felt butterflies in his stomach. He looked down at himself, dressed in nothing but a loose T-Shirt and a pair of baggy shorts. Was he well-dressed, presentable? Anxiously, he fidgeted, before he swallowed his nerves. He made his way out of the kitchen after wiping his mouth of crumbs, and stood by the side of the hot tub.

The only person who could see him from his angle was his brother, whose gaze quickly snapped to him and he bared his teeth. His friends seemed to notice, and the two of them slowly turned in the tub to see him.

"Oh, it's your brother." Kyle sighed, wiping his forehead and brushing down his damp grey fur. "For a moment, I thought it was a burglar or something."

"He was just leaving." Kevin emphasised, ticking his head at Sam to get him to leave. But instead, the cub just stood there, anxiously fidgeting. He knew they were all way older than him, but it was boring just to hang out by himself.

"C...Can I hang out with you guys?" He asked tentatively, and there was an eerie silence between the four of them, before Mike started to laugh. The bear was large, and as he shook his shoulders from laughter, he made the water splash about.

"Aww, the kid wants to join in." He sounded almost as if he was mocking the poor pup. "Should we let him?"

"No." Kevin definitively answered with a sour expression, shifting about in the water. He looked almost uncomfortable. His two friends laughed with each other as they turned towards the cub again.

"Well, you can't hang out with us dressed like that: you'll get your clothes wet." Kyle pointed to the pup's shirt and shorts, and Sam glanced down at himself anxiously. "Wanna help your baby brother out, Kevin?"

The older canine's gaze lowered and he glanced away, rubbing the back of his head. Sam spotted the colour rising to his brother's cheeks. Was he embarrassing him?

"Here, we'll help you out, kid." Mike clambered out of the water, as did Kyle, and Sam noticed the two of them dressed in their own swimming trunks. Or rather, Mike was sported a loose, hawaiian-styled pair of swimming boxers, with floral print and a vibrant flourescent colour, and Kyle was sporting a tight speedo, a rich, deep ocean blue colour that gave him a definitive bulge.

At first, they just stood there, before their hands were upon him. Kyle's thumbs dug into the canine's waistband and pulled down his shorts, sliding past his flat hips and dropping to his ankles. The bunny's hands delved around and lifted up the cub's ankles, leaving him relatively off-balance.

"Jesus, kid, you're not even wearing underwear?" Kyle teased as he got a good view of the pup's small sheath. In comparison to his brother's, he was considerably smaller, but Sam never seemed to have any problem with the size of his package. He was too young to care, at this point.

Sam felt a growing sense of nervousness as the rabbit tossed his shorts aside, leaving him bottomless. He had lithe, almost slender legs for a 9 year old and rather flat hips typical of your average boy. Mike's hands delves to the hem of his shirt, and Sam felt the bear's claws tickling at his white fur. The shirt was roughly pulled up his body and his chest and stomach were quickly exposed. The pup wasn't as much of an athlete at his brother, leaving him looking fairly flabby in comparison to Kevin's chiselled features. Like most kids, Sam sported a small section of 'puppy fat', which made his belly look ever so slightly chubby, but his chest was flat and lacked any sort of extra muscle. Mike yanked the shirt over his head and tossed that aside as well, leaving the pup in the nude. He wondered whether he should have mentioned he could undress himself, but the two of them had done it for him before he'd even had a chance to.

Sam felt a sting of embarrassment up his spine and he moved his hands down to fidget down by his stomach, hovering, wondering whether he should cover himself up or not. Before he had room to decide, a pair of large bear hands tucked under his armpits and lifted him off his feet, leaving his slender legs to awkwardly dangle a few feet from the floor.

"Look at the pup's little dick." Mike marvelled as he stared right at the cub's sheath. "Little balls, too."

The two friends laughed and Sam felt colour rising to his face, making him nervous. He hadn't been complimented like that before, and he had the feeling it wasn't good. Before he could say anything, Mike turned and tossed him towards the tub. He sailed through the air in a matter of seconds and landed in the pool with a large splash. He quickly rose to the surface and spluttered, drenched from head to toe.

With that, the two friends clambered back into the water and glanced to each other as the pup lounged between them. Now that he was in the water and the bubbling liquid kept his junk covered, he felt a bit more as ease, resting his elbows back onto the edge of the tub. Maybe it wasn't so bad, after all. He glanced to his brother who kept his gaze down, and Sam frowned, wondering why he looked so ashamed.

"What, Kevin, you embarrassed that your baby brother is hanging out with us now? He seems cool." Kyle chimed and Kevin looked up to glare over at his friend. Sam squirmed between them. He didn't want them to fall out because of him!

"Yeah, he's cool." Mike chipped it, putting an arm around the pup and sliding him closer. "Maybe he should sit with us."

The Bear tugged the small cub around the water until he was sitting between the two friends, with Kevin directly opposite him. Sam smiled awkwardly, glancing between the bear and the rabbit, and looked at their rather curiously sinister expressions.

Under the water, Sam felt a hand on his upper leg, stroking up and down his fur. He glanced to his right and peered over at the rabbit, quickly realising that the bunny was stroking along his leg. Sam squirmed a little, attempting to shift out of his touch with an anxious grin.

"What's the matter, kid?" Kyle asked, and Sam flinched when he felt a hand on the opposite leg, realising that it was coming from the bear. The two of them were stroking him from both sides and he shifted between them, glancing over to his brother for some support. Kevin stared at him for a moment before he looked away, staring over at the open patio door.

"Hey! What you squirming for, huh?" Mike asked him as his hand dragged up Sam's body, sliding along his slightly pudgy stomach and up to his chest. He felt a sharp claw tracing along his nipple and he shifted uncomfortably, gulping. This didn't feel quite right.

"Stop touching me." He eventually managed to say, tensing up when he felt Kyle's hand sneaking down along his inner thigh and stroking along the soft fur. His fingers were dangerously close to the pup's balls, and Sam definitely didn't like it.

"What? But we're just having some fun, kid. Don't you want to have fun?" Kyle asked with a rather irritable frown as the pup began to push at their hands. But, the teens were a lot stronger than he was, and their hands pushed back at his, not giving up. Mike rolled around to face the pup and used his other hand to firmly grab his arm, keeping his resisting hand at bay.

"Yeah, kid. Your brother likes to have fun, and he ain't a pussy. Are you a pussy, kid?" Mike added as the two of them shuffled closer to the cub, leaving him relatively pinned between their large bodies. They were alarmingly close and it made him uncomfortable, giving him very little room to move. His brother still wasn't looking over, as if he were ashamed to watch what his friends were doing.

"S-Stop it. Please...!" Sam repeated, beginning to feel his heart hammer and the panic rise in his throat. Was it a prank? A cruel joke designed to make him scared? Or was it something more sinister? The duo didn't stop, their greedy hands roaming across his body and stroking along his fur as Kyle's free hand kept his other arm back. He was held down, and a small whimper escaped his throat.

Their hands trailed down the two large, teen palms cupped along his small balls, making him tense and his knees to bend up. He pressed his legs together to try to get them to back off, but only made it worse for himself, locking their hands to his crotch. He looked up at their terrifying face, and Kyle brung his head down. Sam winced and whimpered as he felt a tongue sliding up the side of his cheek, and then another one across the bridge of his nose. The two of them licked his face and pressed themselves against him as their digits rolled around his little balls, making him quiver and tremble.

"He's a sensitive kid. He's got balls almost as big as yours, Kevin." Kyle teased and Sam could hear his brother's brief snarl of disapproval from across the other side of the tub. He felt one of the hands move and slide up his sheath, dabbling down the small little entrance that housed his member. They stuffed a digit against the tip and slowly wormed it inside, with some difficulty. At first, Sam felt a stab of pain, before a sickening pleasure washed over him. This was wrong, and he knew it.

"Little puppy likes it." Mike teased as he felt the kid quivering beneath him. He angled the cub's face and pushed his mouth onto the smaller kid's own, kissing him with a rather odd passion. Sam squirmed under the kissing, feeling the intruding digit in his sheath beginning to circle around his hidden member, causing more stabs of pleasure to shoot up his spine and make his whole body tingle. Another whimper escaped his throat as tears bubbled up in his eyes. He felt a tongue forcing it's way into his mouth and he was powerless to stop it, feeling the tongue rolling around his own, giving him the odd taste of another man's saliva.

"Holy shit, I can go in deep here." Kyle laughed, and Sam soon realised it was the rabbit who was touching him down below. "I'm already half-way in with my finger. The cub can sure take a lot."

Sam arched his back and whined out as he felt the finger stuffing deeper and deeper. He could vaguely feel the sensation of his sheath stretching open to accommodate the finger, and his body trembled underneath the odd touch that left him feeling disoriented. That tongue continued to worm around his mouth as the sheer proximity of the two teens kept his arms from fighting back. Soon enough, the odd sensation stopped, and he heard a short laugh from the rabbit.

"Fuck, Mike. Hey, Kevin, look, I'm knuckle-deep in your baby brother's sheath." Kyle remarked as the rabbit flexed his finger. Sam squirmed under each coiling of his digit, his instincts kicking him and making his body buck and push up against the odd, pleasurable feeling. The very act made the two of them laugh.

"You like it deep, huh little guy? Don't worry, kid, you'll get something deep in you real soon." The Bear growled as he pulled his mouth off the cub, leaving a string of saliva between their lips. "I'm already pretty pent up."

Sam exchanged a wide-eyed, fearful glance between the two of them as Mike's gaze travelled down. The pup slowly gulped and lowered his own gaze, following where the Bear was looking. Slowly, Mike raised himself out of the water onto his knees, exposing the majority of his wet swim shorts to the open air. He paused for a moment as his hand hovered on the waistband of the shorts, and Sam saw a large, tenting bulge. Slowly, Mike pulled it down.

Sam was greeted to the bear's massive member. The length of the member itself could have been 12 inches or more, but the pup was never very good with numbers. The entire length was long and pink, and the head of the cock was lined with four definitive bulbous, red points, asymmetrical and odd-looking. Lower down was the sheath and the bear's massive balls. Mike slowly tucked the waistband underneath his balls, leaving the entirety of his cock out in the open.

"The ladies love his dick, little guy. You will too." Mike grinned malevolently, reaching down with a hand to stroke the almost fragile-looking length of the member, sliding his large paw up and down. A clear-looking liquid dribbled from a small hole in the tip of the member, and Sam fearfully glanced down to his head, before back up at the bear.

"Don't just stare. Suck." The bear reached down and grasped the back of Sam's head, and the pup initially resisted, but was too weak to fight back completely. His head was eventually tugged forwards until his closed lips met with the head of the bear's cock, and he squirmed, letting out a whimper and shaking his head.

"Either open up, or this goes up your ass. Trust me, little cub, that'll hurt more." The bear muttered darkly and Sam emitted a small, fearful squeak, glancing to his brother. Kevin continued to act like it wasn't happening, ignoring his whimpers and cries. Despite it, the pup shook his head again and refused.

He felt the slick feeling of the finger sliding out of his sheath, and immediately felt two, fluffy hands on his head. It was Kyle, and he heard the rabbit snickering in his ear.

"C'mon kid: quicker you suck him, the quicker you can suck me." He grabbed onto the pup's lower jaw with one hand and his snout with the other. Using his teen strength, he forced Sam's mouth open, enough for the Bear to stick the head of his odd cock onto the pup's tongue. Sam whimpered and protested, the tears rolling down his cheeks.

Slowly, Mike slid his cock further and further into the cub's mouth, pushing deeper and deeper as the pup struggled and resisted. The rabbit continued to hold his mouth forcefully open as Sam felt the head of the member smearing against the back of his throat.

"Hold up, Mike," The rabbit began and shifted the group around. He tucked himself underneath the cub's ass, sitting the little pup on his lap. Sam wanted to try and stop him, but he didn't have much room to move, especially with a dick in his mouth. He felt the rabbit's hands sliding down to his small dick again and felt the familiar sensation of a finger slipping into his sheath. A sharp pang of discomfort made itself down in Sam's stomach and a whine escaped his throat. It stung a little but that same pleasurable sensation returned, leaving him with a sickly hum throughout his body.

"The little guy loves it, huh?" Mike commented with a smirk, sliding his cock back and thrusting his hips against the small mouth, cramming more of his dick into the cub's throat. Sam felt the dick sliding and prodding forcefully at the back of his throat, making him whine from the pain. It was threatening to stretch his throat out, and he was beginning to struggle to breathe.

Soon, the pleasure that hummed throughout his body began to grow more intense as the digit dabbled deep within his sheath. He felt a sharp stab of pain as the rabbit forced another finger in alongside the first, and a more pronounced whimper emitted from his mouth, making Mike grin above him.

Neither of them seemed to care too much about the cub's wellbeing at this point. The bear groaned, his large hands grasping Sam's ears and giving them strong squeezes as he forced the small mouth down onto his cock, and the rabbit jammed his second finger knuckle-deep, the two of them sliding and worming between something hidden deep inside.

"There it is. Kid's finally getting hard." Kyle commented, looking down into the bubbling water as he saw the cub's pink tip sliding out from its sheath, pressing in between his fingers and pushing up against the palm of his head. Sam violently shook from the forced sensation as the bear's cock crammed itself down his throat, stretching him completely.

"Shit...I'm getting close." The bear huffed, pounding his hips back and forth as he gauged how much of his thick member was stuffing it's way into the puppy's mouth each time. If he went too far, then he risked damaging the poor cub permanently, and that wouldn't make it fun for his rabbit friend. The tip of his cock slid down into the throat a few more times as his pleasure hit it's limit.

"Fuckin'...!" Mike grunted hard and shoved the cub down on his dick, making him take almost all the member as the tip of his cock shot a thick, heavy globule of cum down into the pup's stomach. He shot another, and then another, spurting thick, heavy gropes of bear cum. Sam's face grew flushed as his airway was cut off, making him unable to breathe. His own little dick was already at full mast, and his anatomy forced his knot to swell, locking it out in the open from his sheath. It had never gotten hard before, but he never thought his first experience with his own dick would be forced.

The bear's orgasm had ended as quickly as it had begun, leaving Sam a whimpering mess. The bear slowly pulled his hips back and the cub took in a huge gulp of air, spluttering and coughing as cum dribbling from his chin, dripping into the bubbling water below. Kyle wasn't letting up with his lewd touching, his lithe, fluffy fingers dancing over Sam's sensitive little cock and tracing teasingly along his knot. Each touch made him tingle.

"You've got a good throat, kid." Mike smirked, his long, thin cock hanging limply in front of the puppy's mouth before it began to shrink a little, slowly retreating back into its sheath. The two friends turned to Kevin, who sat on the other end of the tub. Sam following their gaze and met his brother's own stare. He looked...bored, as if he didn't really care much about what was going on. The younger canine let out a whine. He had expected his brother to do more to help, rather than just sit there and let him be molested.

"You joinin' in or what? C'mon, we've left his backdoor for you." Kyle grinned toothily and Sam saw his brother tense a little, his eyes widening for a brief moment. The older husky let out a exasperated sigh, and rolled his eyes.

"I dunno. Not really into it." He attempted to make himself sound cool and the two friends snickered at each other.

"What, you scared of an ass, or somethin'? C'mon!" Mike egged him on as well as the rabbit slowly started to chant Kevin's name, his fingers pumping the cub's dick in unison with his chanting. The older canine squirmed in the water a little as they attempted to encourage him and he looked over again at the trio. Sam weakly shook his head, his eyes begging, pleading.

"Tch. Fine." Sam could spot his brother's almost embarrassed expression as he slowly raised himself out of the water. Sam's eyes widened as he walked closer, and his older brother pulled down the front of his swimming shorts.

Sam was greeted to the sight of his brother's erect cock. 8 inches of red, wet, glistening canine cock dangled in view, coupled with a large balls of balls that hung underneath, swaying left to right. Kevin slowly dragged his hand from the tip of his tapered end down to the base, and Sam's fearful eyes followed, watching as Kevin's large hand traced across the thick, bulbous knot nestled at the base. His hand briefly tucked under his balls as he snuck the waistband of his shorts underneath them to keep it in place.

As in on cue, Kevin's friends stood and took the cub with them, lifting him up into the air a few feet above the hot tub. At first, the puppy was laying on his back, but he was slowly flipped over, Mike's large hands cradling his shoulders as Sam's face was forced up against the Bear's sheath. He felt a pair of large hands on his hips and realised quickly that they were his brother's. He felt Kyle's fluffy head butting with his stomach, as the rabbit had snuck underneath him.

Sam left out a muffled whimper of protest, sounding almost pleading. He wanted this to stop, but they were having too much fun. He felt something warm and thick sliding up against his small behind and heard Kevin groan behind him, out of view. Mike's hands held him firmly as he felt the sheath against his muzzle pulsing and swelling under his small lips. He could feel the tingling around his dick again as Kyle's fingers wrapped around his small cock, giving it a few eager tugs.

"You look pretty pent up, Kevin. Did you know you were gonna fuck your brother's ass or something?" Mike joked with his friend and he heard Kevin snort a little, sounding almost a little amused. Sam could feel a warm, sticky substance smearing itself all over the fur around his ass, stickying it up. His little pucker spasmed and tensed with each firm tug of his little cock, and the tingling was quickly growing more and more intense, making his mind hazy with fear and the faint feeling of desire.

"Shut up." Kevin grunted to his friend amidst a chuckle, slicking up his thick member with the pre-cum that dribbled from his tip. He watched his brother's wiggling behind with unabashed lust. Perhaps it was wrong to want his brother's underage ass, but he didn't appear to care, in that moment. His uncomfortableness with the situation had turned into a pure need to breed his little brother into a spasming mess.

Without a word of warning, Kevin angled his hips back and began poking the head of his tapered end against the clenching pucker, feeling it tense and try to push him out. He heard Sam's panicked whimpers and whines, muffled out by the amount of bear fur rammed up against his face, the pup's arms firmly locked and held tight. Kevin tightly held his brother around the stomach as he pushed his hips forward. With some difficulty, the pucker eventually spread itself open and began to accommodate him.

The first thing that Sam felt was the searing pain that spread throughout his backside and shot up his spine like a rocket. A sharp scream erupted from his mouth that became a muffled cry amongst Mike's crotch. Kevin let out a lewd groan as he pressed himself further, hearing his brother's screams, managing to make out distinct syllables that he guessed were words like 'stop' and 'please'. But, he ignored them, stuffing himself further and further. Sam felt nothing but the pain for a long time as he legs trembled and his inner muscles clamped like a vice.

Kyle was having the time of his life underneath. With each clench and squeeze, he could see the little puppy's dick twitching and hardening, which only tempted the rabbit further. Eventually, his bunny lips wrapped around the tip of the small cock and he pushed his mouth down onto the small, knotted cock, slathering his tongue all over the length as Kevin continued to cram himself inside the tight ass.

Inch by inch, Kevin buried his thick member inside his little brother's ass, watching the tight ring redden from the sheer stretching. After a few moments of forceful pushing and rocking, he was buried up to his knot, the thick base pressing dangerously against the ass, making itself known. Sam whimpered and cried out a good few times still, even if the initial pain was over.

"How tight is he, huh?" Mike asked with a sinister grin as he hips rocked and bumped against the cub's lips, his cock slightly peeking out. Kevin didn't appear to answer, his breath coming out in hot, sharp pants. Inside the cub's ass, he could feel the muscles periodically squeezing and milking his member, causing it to spurt small strings of pre-cum into his little brother's asshole. Each pulse of his cock made it press against something sensitive inside the pup, making a few of Sam's moans of pain turn into small, almost effeminate huffs.

Slowly, Kevin pulled back as Mike snickered to himself, looking down at the muzzled buried amongst his crotch fur. Kevin slipped his cock out almost all the way to the tip, and then humped forwards, tugging Sam's ass down onto his dick up to the knot in a single thrust. Sam let out a wail of pain and scrunched his eyes up as tears freely bubbled down his cheeks, his toes curling from the pain. Amongst it all, he had felt a brief wave of pleasure and make his dick pulse inside the rabbit's mouth, coaxing the bunny into bobbing his mouth against the small member. The pleasure somehow made it hurt less, but it was still painful nonetheless.

"Fuck..." Kevin muttered to himself, pulling back an inch or two and beginning a steady rhythm of humps typical to most canines. His thrusts came out in short, quick bursts, his fat balls swaying violently and smacking into the small cub's own as the air quickly filled with the hot, wet slaps of his knot against the tight, underage behind, couple with Sam's grunts and cries of discomfort and pain.

But, Kevin didn't seem to stop. In fact, he only sped up, pistoning his hips back and forth like a machine as he humped and thrust, his fingers digging into the flesh of his brother's stomach and hips. His tail wagged furiously behind him as the pleasure swamped his system, making him grunt and huff like a dog. Mike and Kyle watched with some degree of fascination at how into it Kevin was getting.

Kevin had become a breeding machine, caring little for his brother's safety and well being in his lust-driven state. His claws dug into Sam's flesh as the cub spasmed and groaned from the sheer force of his short thrusts. His pre-cum was near-copious, and each withdrawal of his member caused some of it to dribble out, causing the collision of his knot against the petite ass to be rewarded with a thick, wet splatter of pre-cum that coated the pup's ass and his own crotch.

"Fuck...I need..." Kevin groaned out, almost drooling from the pleasure as his thrust forward grew rougher and rougher. With each pump of his cock, he kneaded his hips into Sam's behind, tugging him firmly down against his knot as he tried to force it in. Mike and Kyle were almost a little speechless, but it was definitely a hot sight to them, somehow. Kyle's mouth pushed firmly down and locked around Sam's knot, tugging with his lips and smearing his wet tongue around the small knot as Sam's pained grunts turned into short, muffled moans. Tears rolled down his cheeks as his eyes rolled up into the back of his head. The pleasure was suddenly so intense in such a short amount of time.

Despite the puppy being on the cusp of his orgasm, Kevin tried to knot the child, forcing his cock hard against the tiny ass until he could take it no more. With all his might, he thrust, tugging his brother's ass down as hard as his could. Sam let out a weak whimper of pain before his ass finally gave way and loosened. Seeing the opportunity, Kevin quickly humped further and his knot popped firmly into his brother's ass, stretching his inner sphincter to it's limit.

The two of them orgasmed at the same time. Kevin let out a thick, heated groan of pure ecstasy as his cock pumped thick globules of cum, shooting heavy ropes inside his brother's asshole, Sam's small stomach swelling and bulging from the sheer amount of cum that filled him up. Kevin kept convulsing and cumming, rocking his his against the asshole and occasionally yanking his hips back to heighten to pleasure. The pup had orgasmed as well, but nothing came forth into the bunny's mouth. His little dick twitched and Sam felt pleasure and pain swimming throughout his system as a long whine escaped his mouth. His eyes rolled into the back of his head, and suddenly, everything went dark.

"...Kid. Kid? Shit, Kevin, I think he passed out." Mike gently shook the pup's front end and watched as the kid's arms went limp and his back bent a little. "Wow. You really did a number on him."

The three of them stood there in silence for a moment and then began to chuckle amongst themselves. Kyle drew his mouth back to see the small dick standing to attention still, the knot firmly locking his cock in place. Kevin remained firmly embedded in his brother's behind as Mike slowly brung the pup up a little, angling him fully vertical and leaving him pressed, passed out, between the bear and his older brother.

"So...what not?" Kyle asked the pair of them, wondering if they'd even be in trouble for raping the poor kid. Kevin rolled his shoulders.

"First, we wait," Kevin guessed. "I...uh, I take about half an hour to go down."

"Half an hour? Shit, Kevin..." Mike laughed to himself. "Well...we'd better think of what to say to him when he wakes up."

"I've got an idea," Kyle chipped in with a smug grin on his face. "We should say: 'Round 2?'"

Mike suppressed his laughter as Kevin snorted loudly. The three of them began to laugh amongst themselves as the cub hung limply between them.
