After their steamy fuck session, Joey was all set to call it a day and go to sleep. However, Riley was still as hungry for sex as ever. He pulled his little brother by the hand towards their parents' bedroom, ignoring Joey's whines and protests that it was his and Riley's "special spot."

Entering the master bedroom, Joey's nostrils were filled with the scent of their parents' sweat and musk. The smell instantly aroused the preteen boy, and he watched eagerly as Riley rummaged through their parents' belongings.

Suddenly, Riley pulled out a long, thin dildo that was nearly as thick as Joey's leg. Riley's mouth turned up in a wicked grin as he held the dildo in the light, showing it off. "Look at this, buddy. Mommy's got a big little secret~" the goat brother sang.

"Woah... that thing's bigger than my leg!" Joey exclaimed, marveling at the size of the shiny silicone toy.

"I'll make a deal with you, cutie," Riley said, placing a furry hand on Joey's bare back and caressing him. "I'll shove this bad boy right up your tight, little butt, and you get to ride my fat, juicy cock afterwards~. Sound good?"

Joey swallowed, not entirely sure how much his ass could take. But he was more than curious to find out. So, after a brief hesitation, the small boy nodded his head.

"Y-yes, brother. Put that big, fat thing in my butt!" he said excitedly.

"Mmmm, perfect, little buddy~" Riley growled softly. The eager youth got into position, bending over so that his hands touched the floor. His smooth little buns pointed straight at Riley. Joey had always thought his brother was the smart one. In a matter of seconds, Riley was applying plenty of lube to Joey's sexy rump, making sure his ass hole was thoroughly lubed and his skin was slippery. Then, he went in with the rubber shaft and pressed the tip to his little bro's tight pucker.

Joey could feel his ass spasm when the tip of the toy poked his hairless ring, but kept himself relaxed and calm so that his big brother could push the dildo in easily. The lubricant seemed to flow over his tight little anus as Riley began pushing harder with the rubber pole. He used one hand to steady himself, and with the other hand, he forced it in. The slick friction began, and Joey cried out.

"God, brother! That's so big!" the young boy squealed in a high voice. The younger boy's stomach twisted in excitement as the large dildo slid farther and farther up his cute butt. "I...I think I'm ready for your dick!"

Joey trembled with pleasure as Riley shoved more of the girthy rod into the youngster's tight furry asshole, each push sending tremors of pleasure through his loins. The elder brother grunted with exertion as the toy began to slide all the way up the boy's guts, its rounded end nudging deep against the 12 year old's prostate and making him squirm with joy.

Joey cried out, feeling full like he never had in his life, and his body stiffened as a warm sensation built up within his crotch. Suddenly, with a loud shout, the young goat spurted cum out from his uncut cock in thick strings of white jizz. He looked down, watching as the thick globs of semen splattered against the floorboards.

"That's right, Joey, cum like a bitch in heat!" Riley growled, fucking his little brother with the toy, bringing him more and more to a climax. The vibrations and ripples made the dildo quake a bit inside, and Riley twisted and twisted, making the rubber shaft swirl around inside the kid's colon.

Soon, it was almost too much. The preteen's young, inexperienced mind couldn't process the feelings of blissful, exquisite pleasure flowing through his veins, and his body shook violently.

"Uh, uh, AHH! AHHHH!" the little goat yelled in orgasmic ecstasy, his tongue rolling out the side of his mouth and a little drool running down the side of his open maw as his lithe, underdeveloped body was assaulted with the intense sensations of pleasure. His erection twitched, the tip red and dripping, his balls contracting. And when it felt like Joey had reached his absolute peak, Riley gave one final, hard jab into the boy's tight rectum.

Riley could hardly keep himself together. The way that Joey screamed, his high pitch ringing through the room, made his erection throb wildly between his legs. He felt like a caged beast, desperate for release and so incredibly close to the ultimate goal of ejaculating. All he needed was to feel Joey's warm little body writhing on top of his big, juicy, needy rod, which the small goat obliged. Joey climbed shakily onto his knees and reached for his brother, sliding a soft paw down his torso and around his bulging package.

He tried to reach under his heavy balls, searching for that rigid member buried under that heap of hefty, stinky sack, but Joey could only brush against it. So, he grabbed Riley's dick, and lifted his fuzzy balls up to his face. Taking a deep whiff, he inhaled the overwhelmingly strong scent of male musk that emitted from that fleshy pouch, the very source of Joey's genes.

This just seemed to enrapture the horny little boy, making him gasp and giggle as the scent went straight to his head. This feeling was clearly visible as his eyes rolled and fluttered slightly, and his nostrils flared slightly as they tried to consume that intoxicating scent even further, until he could no longer see anything but the balls before him. They were big, and bulbous, covered in a fine, brown fur, and with a reddish underside that grew darker and darker the closer you were to the heavy orbs contained within. He nuzzled them lightly, sniffing loudly and moaning at the intensity of the scent, and his precum-splattered chest heaved with barely-concealed anticipation.

"Alright, come on you horny little pervert," Riley chuckled, his deep laugh resonating in the small boy's ear. "Show me just how much of a man you really are."

At those words, Joey shivered a bit, a new excitement making him fumble slightly with his big brother's length.

With his free hand, the boy slowly started to pump his older sibling, working that giant schlong, using the older goat's pre-cum to lubricate his brother's cock, coating it from the tip down to its base. Meanwhile, Joey reached behind him, searching with his fingers for that pulsating heat. It took some fumbling, and rubbing along the outside and brushing against the dampness and the fuzzy scrotum, but Joey did it. He grasped hold of that thick cock meat, feeling it twitch, the skin gliding over it.

Joey heard his big bro mutter something incoherently and grunt as his grip tightened just slightly. With one last shaky sigh, and one last lingering glance up at Riley, Joey lowered his body until he felt the leaking tip of the pulsating penis brush against his tail. Then, as a pleasurable groan escaped his older brother, Joey relaxed his anus and let that wet, flared cock-head enter him.
"Oh, god...!"

Joey released a trembling gasp when his body felt the initial intrusion and pressure of his brother's massively-sized member. He shifted, trying to get into a better position, his butt wiggling. He placed one hand behind him, steadying himself. Then, taking one deep breath, he sunk down onto that massive thing.
"Geez, damn, o-ohh," he gasped, looking down in shock at his stomach. With an impossibly huge thing sticking out of him, he looked pregnant. In fact, Riley could have sworn there was a bulge where his cock pushed down. It was rather amazing, and just thinking about it caused the huge rod to stiffen and swell, causing the small child to wince and take in a quick sharp intake of breath.

But there was no doubt, Joey wanted to feel his brother's full strength. Wanted his little brotherly guts fucked and ravaged like no other. Like a real brother should.

Riley watched intently at his little brother's reaction, watching carefully for any discomfort. Though, seeing his dick go straight in with such ease and feeling his tight insides contract so eagerly, the goat elder could hardly help the low, reverberating snarl that erupted from his throat as his little sibling slammed down. Joey's snug little hole swallowed all nine and a half inches of thick, juicy goat-man cock.

It wasn't long at all before he lost control of himself, moving his hips in the most unpredictable of ways, drawing an equally unpredictable reaction from his little brother. Joey whimpered, a whimper Riley recognized as being one that he'd let out while they had their way with the toys earlier. That whimper that usually let Riley know just what Joey was about to do. It sent a shudder straight to his swollen rod, and he could feel his little boy's boi cunt getting wetter and tighter with every stroke of his dick.

The 12-year-old had a mixture of emotions flowing through his body - nervous, happy, scared, anxious. Joey wasn't sure what to expect. Was it going to hurt? Was it going to feel good? All he knew was that Riley was his hero, his savior, his everything - and now he would become his master, the dominant one.

But after having a giant object up his butt only a few minutes earlier, he thought that maybe this wasn't that different. It actually didn't feel painful, other than the slightest twinge of discomfort, a kind of strain from the intense friction his bottom was experiencing. Instead, it was simply thrilling and amazing. In fact, Joey began to love how Riley's dick just slid along with ease, only brushing against a particular part of him that made the tingling in his loins multiply. Joey would just have to find out where that spot was...

Riley gave one huge thrust of his pelvis, grinding his balls on his little brother's tushy. He relished how Joey's body clenched tightly on him as the boy let out a wild cry. His long tongue extended far past his lips, curling and swaying around in the air. He wasn't entirely sure he had gone far enough in yet, and so Joey used one shaky hand and pushed a finger in the boy's little pussy to gauge if there was any further progress. Sure enough, there was more cock-meat to squeeze, and with his curiosity fueled, Riley could do nothing more but let out a triumphant laugh as his cock found its way to the 12-year-olds limp little appendage.

Now, Joey was well aware that Riley was inside of him, he could feel it. Not only that, but that there was much more still left to take, and was eager to see how much his anal cavity would expand and contract around the massive girth. He glanced over his shoulder, the glimmer in his eyes making the elder buck feel his pulse rise.

And then, without warning, Joey forced his body upwards and fell again, and it wasn't so bad this time either. Only this time, the elder brother noticed how much his little bottom hole seemed to flutter around his fat meat. Oh god, how he'd always wanted that feeling, always wondered what it was like, and now it was the most amazing experience in his entire life. So much pleasure, so much ecstasy in those few simple thrusts and the younger goat felt his belly begin to stir as the pressure of his erection only grew stronger, leaking a small glob of his precum.

With a sharp inhale, Riley wasted no time in pulling his brother down, thrusting his hips up and plowing his brother deep with another moan of satisfaction. Joey grunted, a thick line of precum dripping down his tiny shaft. But it was so satisfying, oh god, and it was like a dream come true for the both of them.

Now with an established rhythm, the older brother thrust his pelvis up into the soft flesh of the younger sibling's round tushy. Over and over again, making the smaller boy grunt with each deep penetration.

Each and every powerful thrust that Riley would make had an immediate effect on his young, tight lover, whose breathing turned erratic and shallow from the overwhelming pleasure he was receiving. "Yes! Yes! Don't stop big brother, please, I can feel you in my stomach! Please go deeper!!!"

Those screams of wanton delight were all the confirmation Riley needed and he slammed hard into his kid brother with a primal grunt and growl. Both kids began panting harder as the slapping of flesh against flesh increased, each impact causing a loud and obscene 'smack' followed by a whimper or moan from the younger child.

"Oh god R-rye! Fuck me harder! Make me cum, please, don't stop!"

Upon hearing his younger brother's desperate plea, Riley quickened his pace, giving powerful smacks into the boys rump at the end of each thrust and reveling in the noise of his balls slapping off his cute brothers' own.

A very visible bump was forming in Joey's flat, slim belly due to Riley's big, plump mushroom crown digging deep. Each hit made an audible and perceptible bulge as his fat mushroom cap pounded the small stomach from the outside in.

Joey cried out with all his might. His voice was hoarse, his face flushed. And as Riley felt the young body quiver and tighten around him, he too reached climax and his muscles clenched up tight. Riley howled out and squirted a copious load deep into Joey's gut, and they collapsed together. Joey let out a euphoric laugh, squirming as his hole was pumped full of hot goat jizz.

Riley and Joey laid there, entwined, the adults arms around the youths tiny frame as their sweat drenched, flushed bodies recovered. Finally, with a gentle and satisfied smile, Joey looked down upon his blissful older sibling.

"Damn Rye, this is so cool..." he whispered quietly, kissing his lover. His bright, cheery eyes were clouded by passion and lust, and he could feel his warm seed start to dribble down his leg.

But there was also love, and adoration, for his elder brother. He didn't think their bond could be even more strong and complete. Until his gaze moved to his lover's fuzzy ball sac, coated in cum, and the sweet smell wafted from the sticky, warm orbs. And what happened next was even more shocking for both of them.

"Holy hell..." Riley moaned as his baby bro wrapped his arms around him. One went across the back of his hairy shoulders, while the other went around his neck. Then, with the youngest goat holding his big brother tightly, the smallest child pulled their chests together. Joey reached up and pressed his lips to his big brother's, before closing his eyes and kissing him tenderly and passionately. Riley's cock throbbed deep inside the boy, and Joey's eyelids twitched in the ecstasy of the kiss. As his brother returned the favor, Riley closed his own eyes and lost himself in the intimate exchange. The moment of their first kiss.
He could feel Joey's soft lips press against his. They were tender and smooth, and his tiny frame clung to the elder goat, and the boy's arms held him close, and it was so loving. But as their tongues met, something stirred within him. The desire.

It was a powerful, passionate desire. He could feel the boy's chest beating against his own, and the taste of his kiss made him hungry for more. The scent of the boy's hair and the feel of his warm, smooth skin sent a tingling sensation throughout his body, and he couldn't resist the urge to wrap his arms around the boy. He ran his fingers through the boy's soft, silky hair, and held him close.

They kissed, and they kissed, and the world disappeared around them. There was no need to say a word.

The two siblings continued to explore each other's bodies, growing more and more comfortable with the intimacy. Soon, they were lying in bed together, completely naked and wrapped up in each other's arms. Riley was on top, and Joey was on the bottom, with Riley's head resting on Joey's chest and his arm wrapped around his little brother's waist.

As the night wore on, the two boys continued to enjoy each other's company, and they slowly drifted off to sleep, content with the newfound bond they had formed.

In the morning, the two goat brothers woke up in each other's arms, still naked and wrapped up in each other's arms. Their heads were pressed together, and their bodies were intertwined. Joey smiled and whispered, "I love you, Rye," before closing his eyes and drifting off once more.

Riley couldn't help but smile back. He knew that this was only the beginning of a wonderful and fulfilling relationship between the two of them.
