Sun warmly shining on a raspberry-topped head as the boy trudged his way home by himself, bookbag loosely hanging from one shoulder. He glances up to look around, surrounded by the sights and sounds of a new spring, his large ears perked up high and pale blue eyes darting from left to right. The boy’s tail, curled into a wisp that made it look like a soft flame, fluttered a bit in the gentle, warm breeze, bringing a scent of fresh flowers to his twitching, pink nose.
“Not fair…”
With a sigh, he continued along, his hand flexing as if to hold something. The day was still early, not even noon, but the boy had been sent home, now missing the embrace of another holding his hand for this daily trek. With a day as beautiful as today, he would have loved to pull his older brother along, racing along the sidewalk and waving to the passersby as they went. Even now, there wasn’t a single soul or car in sight.
His paws pressed against the warm cement as he scratched at his tummy just a bit, turning to step up a path leading to a two-floor home. With a hop, he climbed the tiny staircase to reach the porch, staring at the large, wooden door looming over such a small boy. He had to stand on his tiptoes to reach the knob, turning and letting the door slowly creak open as the hinges pulled it inward. He poked his head inside, calling out to the house.
“Daddy?”
No reply. Of course not. There was a groan as he slid the bag from his shoulder to the floor, leaving it behind while stepping into the house’s living room. Hadn’t they called to say he’d be home? It would’ve been nice to have anybody… (What?) The little bunny’s mind raced as he started to walk to his room. He had the entire day, until his brother brought today’s schoolwork to him tonight, to play games and exercise, keeping in shape for his next track meet.
His nose perked up as he moved to his bedroom, halfway there yet caught by another scent. The little bunny-eared boy, with such a big, wispy, soon turned his head towards a door, a tiger-striped sign hanging over the top as it was creaked open. He pressed on it, letting the hinges swing, peeking inside at the floor strewn with toys from the night before, soccer uniforms and school uniforms hung neatly, a bed hastily left behind and all of it alight with a new smell he’d never noticed before.
His steps were cautious, careful, yet surprisingly springy as he stepped into the empty room, keeping his nose in the air. The new scent that radiated all about drew his attention to the bed, though he looked about now, spying a desk with a familiar photo and several books a few grades above his. With a few more steps, the bunny boy would find himself holding the photo, a tall, red-haired bunny patting the head of himself and a slightly taller, pine-haired boy with stripes on his arms.
“Hayden…”
One hand on the pine-haired boy’s photo as his other hand slid down. In his head, he finally connected the dots, the scent in this room clearly making him think of, maybe even want, his older brother. He turned to the bed, two steps forward as his shorts slipped off, a little climbing as his snout pressed against the pillows and covers. His big ears pinned back a bit as his tail bristled, flicking excitedly and making any viewer think a cloud was moving.
It was still warm… That’s what he thought as he picked up the scent of his tiger-striped brother, arching his back slightly and pressing in. His tummy felt warm… No, not quite. Deeper than just his tummy. A persistent warmth and itch, building since he’d woken up this morning, but only now reaching to where he felt a need to notice. He slid one paw to his tummy, then lower, across the curvature of his body before touching at… something soft. Softer than last time, at least, and puffy as well, dripping onto the sheets.
“Ahhh…”
His fingers moved in a soft glide, sliding along the cleft of his lips between his legs and sending a shudder through his body. He’d touched before, after a bath together and curious why he was different from his brother, but the sensations ripping through him were far different, sending a shock that made him gasp out before biting his lip. His tail gave a flicker from left to right, bristling as he closed his eyes, thinking of the boy he could smell and pushing just one finger inside, searching for his hot itch.
Every touch against the soft, slick walls inside him sent sparks through the boy’s body as he pressed through, gasping for air and feeling the juice his body was drooling coating his finger. It was thin, keeping him nice and smooth until he felt the knuckle of his finger against the puffy mound outside. His nose stayed on the scented pillow, mind swimming with thoughts of those striped, older paws holding his hips. His eyes closed, and he could almost swear he could hear the door creaking open, or smell that older boy, or-
“…Tristan?”
“H-Hay…”
Fingers delving deeper inside himself as the raspberry boy whispered, muffled by the pillow. He opened one, pale-blue eye, looking to the door of his brother’s bedroom. In his head, he knew… It was far too early. And yet, he saw that scraggly, pine-green hair atop white fur, the tiger stripes, the light blue uniform of their school’s sports teams. “I…” He felt his throat catch a bit, the older boy approaching the bed now. It was just as a paw was reaching to him that his thumb grazed over the button atop his soft, drooling mound.
With a snap, Tristan’s body jolted upwards, quivering heavily as his thumb pressed that button more and more. His eyes closed again, his body rocked forward to rub on the pillow, drooling some kind of juice deep into the fabric before, with a noticeable shudder, he squeezed his legs together, a heavier fluid squirting onto the pillow, and even the sheets, as he gasped for air. After a few moments, he finally opened his eyes again, hoping to see… Yet he was still alone, the warmth and itch inside him even worse as he climbed out of the bed, dripping all the way to his room.
The little bunny stumbled as he reached his room, turning to land on the messy bed from this morning, staring at the ceiling. His breath came in heavy gasps as he looked about, heaps of clothes that he’d hugged the older boy in and toys strewn about the floor that they’d played together with… His own desk photo that of him and a purple, slim squirrel giving each other an affectionate nuzzling. He’d been in such a rush to see Hayden and go to school today that he hadn’t cleaned at all, and now everything in the room made him think of the boy, of how Tristan was more like his mother, of…
“Does Mom get like this too?”
Distracted, he let his fingers return to the mound between his legs, pressing two inside, then three. His back archs into the bed, thumb pressing on the button as before, working himself into a hot frenzy of moans, needing almost no time before he tenses and squirts that juice out of himself again. His mind feels addled, almost dominated, as he can’t escape the feeling that something must be inside him… Not the fingers. They weren’t easing these feelings, and he let out a whimper as his eyes drifted over his clock.
Three o’clock… He’d been at this for hours? Sitting up in his bed, his nose twitching madly, the boy couldn’t help noticing a new scent draping over all of his things, even stronger than Hayden’s scent, though it certainly didn’t rile him up like the older boy did. He gingerly hopped out of bed, only to stumble as his feet hit the floor, legs wobbly from the way he’d been working his body. He smelled… like he should get a bath. Tristan had to walk slowly, panting along the way… So loudly that he didn’t hear the front door creaking.
“Be careful with your brother, okay?”
Looking up at the white-furred, red-haired bunny, an extra full backpack on his shoulders, the little cabbit would smile and nod.
“Mmhmm! Hold my breath, in and out. I know, Dad!”
Pine-green, shaggy hair atop his head flapping a bit as he nodded, spotting the slumped backpack of his younger brother and taking it along with him. The boy bounded up the stairs to the second floor that they shared, nose already twitching with scents permeating the entire floor.
He hadn’t expected it to be so widespread… The entire floor was coated with the scent of a rabbit’s and a squirrel’s heat, droplets on the floor showing that the little hybrid boy had been moving. Just noticing the scent was enough for the cabbit’s briefs to get a little tighter, but he had a job to do that came first.
“Now, is he in his… Oh!”
Eyes drifting to his cracked open door, the older boy took a few steps to peek inside. His room was empty, to his relief, but as he looked, he could tell Tristan had been in his chair, on his bed… The smell was everywhere, and far stronger than the hall.
He needed to step out, and quickly, shutting the door with a note to tell his Dad later. Down the hall, passed the bathroom, the heat just getting stronger and stronger. He reached Tristan’s room, the door adorned with maple leaves and a name plaque shaped like an acorn, a little trick by their dad to remind the boys of their heritage. Hayden took a deep breath as instructed, reaching for the knob and opening the door. “Tristan? I brought your schoolwork… Dad said you need to stay home for a few days.” Calling out as he watched the door swing and reveal the empty room.
“He’s not…? Where did he go?”
Hayden was bewildered. The room still held a fresh scent inside, and he left bags behind while closing the door… He was a star student, he could get his work later. “Tristan?~” Looking around the top floor, in the closet, back in his room, and, finally, to the bath. The door was cracked open, yet he couldn’t hear or smell anything. “Maybe he went outside… or to Dad?” Pushing on the door as he spoke, letting it creak. The cabbit let out a sudden squeak as he was face to face with the lavender-furred, raspberry haired Bunnel.
“H-H-H-Hay…”
The younger boy looked up… His naturally pale eyes had a faint glow, filled with tears. He stared at his older brother, then squealed, tackling straight into the cabbit and knocking Hayden to the ground. 
“It’s you! The real you!”
Tristan’s body was soaked, glistening with water from his bath. He straddled the winded, older boy, rearing back in such a way that the puffiness of his mound was easy to see. The water had kept his scent from drifting much, but now it could resume in full force. 
“I've thought of you all day~” His paws placed firmly on the cabbit’s chest, panting heavily.
It was almost intoxicating. The way the younger boy smelled, how his body swayed, his wet fur glistening while his eyes shined down on the cabbit and those tiny paws traced the older boy's body. Hips pressing forward met with the bulge of the boy's shorts, still loose in his soccer uniform and unable to hide how his body was reacting... not that he would. Every one of his senses almost screamed mentally to Hayden, arms moving automatically to grab Tristan's hips, every ounce of his being saying this boy needed him right now. 
"Tristan... No... But- I... W-we'll be seen." 
Holding to what little reasoning he could now. Massaging the bunnel's waist with his hands and looking up. He stared into those blue eyes, remembering that he'd promised to be careful... (careful of?) The thought crossed his mind and he held onto the bunnel as he sat up, noses touching, a shy little giggle. Right, careful of that... The floor was hard, they should be careful of where this happens. (He wants it...) A little nudge as Hayden nods his head toward the end of the hall. 
"Your bed..."
No more words were needed as the bunnel took hold of his brother's paw, just a nod of agreement as he tugged the cabbit to his feet... down the other side of the hall and into Hayden's room. He felt resistance... Hayden wanted the other room but his head looked over his shoulder with a smile. He released Hayden's paw to run forward on the bed, in an instant that fluffy tail drifting to the side as his nose touched against the pillow from before, still marked with his bodies needs... That was a good word for this. He needed that older boy, it just made sense. 

Again, like this afternoon, he saw Hayden in the doorway. The older boy shut the door and began to undress, and Tristan covered his eyes, burying his face in the pillow coated in both their scents. 
"Please..." 
Moaning into it, hoping that finally that the boy was actually here. He'd lost count of how many times he'd seen that scraggly pine-green hair as his body had grown hotter, itchier... It was even beginning to ache as it burned inside him, dripping as if the fluids were being chased out to make him hotter. He needed Hayden, his brother could make it stop. That's what his body told him. 

It was different though, as he let out a loud whine the second the paw touched his waist. He could feel the weight of the bed shifting as Hayden climbed up, the stripes just barely visible on the older boy's paws holding his waist. In an instant, the boy gasped, how his entire body quivered as if it didn't need to hold back. The air that had the twinges of Hayden's scent now turned heavy with his own, his body drooling out and his eyes squeezed shut until it felt something pressing against those lips... Much thicker than his fingers. 

One paw left Tristan's waist, touching just above the base of his tail. He could feel the fingers as they sifted through his fur, up his back, until it was between his shoulder blades. His body was trembling, ready for what it told him was next, yet he couldn't help but wonder. All of this, it was so intense and new, yet it felt normal. It felt good in a way. The thickness pressed against his lower lips started to push, he could feel his body opening for it, and how it needed to squeeze to fit inside his tight tunnel.

"Why does it feel like this?"

The question caught Hayden off guard as he positioned himself behind the younger, heated boy. He had experience. He'd grown up so far with it, after all being with his dad and the other bunnies around the house. He'd forgotten that Tristan was only beginning this new lifestyle. Leaning down he let his hips push in, spreading the boy a little more while that tail cushioned his torso, rubbing along the back with his fingers. His voice gentle and soothing. 
"You're in heat. It's okay... I'm going to help."

His hips rocked, pushing into the velvety folds of the younger boy, soft and slick from the wetness leaking out, so much so that Hayden needn't worry about hurting his younger brother. He didn't have a particularly large size, but that made it even better for the bunnel, soon fitting all the way inside as his length gave a pulse and a twitch. He felt the body below rumbling. A few gasps sounding out and slowly he pulled himself back out, the entire way. 
"Tristan... Hold still okay?" A nod in response from the boy, Hayden stepped off the bed and knelt down.

His tongue slipped out, pressing against the bunnel's lower lips and lapping at the juices drooling out, his nose twitching over and over. This close to the source of the boy's heat, his senses overwhelmed, easily noticing how sweet his brother tasted, how warm he was inside, slipping that tongue down to press against a nub of a button on Tristan's body, again and again until that tiny boy was writhing in pleasure. "A-aaaaahhh!" That gasp... he knew, and his eyes closed as Tristan tensed, hips pushing back against the snout as his body gave a squirt and coated Hayden's muzzle. 

"There... This is going to help a lot." 
Tristan was panting heavily as he heard those words, feeling the cabbit position his hips as the older boy climbed back up. His body slumped, worn out from the intense way that tongue had made him feel, and there was a low moan leaving his body. He felt the member pressed against his lower lips again and he gripped the bed sheets as Hayden pushed inside, the older body pumping in and out even thicker than before as he squeezed around it... he didn't know that the boy's thing could feel so big. 

Hayden's paws moved up to the sides of the smaller boy's body as his hips kept pumping, quietly urging Tristan to relax. A gentle vibration built behind him as his older brother began to purr, sinking the thick member deep inside as if he wanted to scratch the 'itch', though he couldn't reach it. Torso against his tail, he noticed a shift, the cabbit was leaning forward more, and he opened his muzzle to speak... only to moan out as his teeth carefully clamped around the large, pointed ears, nibbling peacefully.

The teeth kept grinding, teasing the little one in brand new ways as he squirmed, pulling the bedsheets up slightly and squeaking at the cabbit. Hayden's arm slid up, embracing his younger brother as he felt the pressure inside growing, Just a little more... He wanted to make that bunnel feel good. A few more thrusts, moaning out together, the bed shifting and squeaking, both boys so loud and distracted that they didn't notice the creaking bedroom door. 

Hayden finally began to slow. He pushed inside as he chugged the bunnel's body to him, that soft tail like a comfy cloud between them. The throb of his nethers quickened and the pressure released, a quick shot of thick fluid moving from him into his younger brother as his eyes closed and he pushed his hips back. Finally releasing Tristan's ear, he moved his muzzle right to the top of the head, giving a soft kiss in the hair. The bunnel's body was heaving a bit... That must've tired him out more than most activities. 

"You'll feel better soon... Just take a nap." 

Petting along his brother's side as he slowly pulled himself out, Hayden watched as that heavy breathing slowed, chest rising and falling until the spent bunnel was sound asleep. His nose twitched, the heat fading a bit when he pulled away from the younger boy, realizing he was covered in both their sweat and pheromones. "Ummm..." He was slowly returning to his senses as he went back to the bathroom to wash off, checking the time along the way. Dinner should be just about...

Sitting bolt upright in the rub of water, the cabbit's eyes went wide... Dad was home, he promised that the three of them could bond together since this was Tristan's very first heat. Letting out a groan of worry, he left the tub to dry off, slipping down the stairs while still stark naked, he bee-lined straight for the kitchen. A pot on the counter, with food still cooking inside, was all he noticed as he looked about, no rabbit insight, and found his step stool to climb up and look at the pot, spotting a note on the side of it.

"Slow cock tonight so Tristan can nap after you two have finished up~" 
...Oh. Climbing back down, the cabbit quickly made his way across the floor, passed the stairs, all the way to the other rooms nestled nearly in the corner of their home. His paw reached up, knocking on the last closed door in the hallway, listening to the voice inside as he spoke up. "Dad?" There was the sound of shuffling, and he waited patiently for the door to open. It swung back on its hinge as he saw the nude, white-furred body of the adult rabbit smiling at him. 

"Were you watching? ... I'm sorry I forgot." 
The cabbit was ushered inside the room, eye on the rabbit as he saw there bright blue eyes and the ruffled red hair. He was led into his dad's bed, seeing something familiar on the covers... A photo album, one he knew housed of himself, his parents, his grandparents.... intimate photos of their family's time bonding with one another. There was one new one, in the hallway... Tristan's body atop his own. 
"It's okay-" his dad's voice cut in, a bit as he smiled, petting the cabbit's head to earn a gentle purr, "-we both know how us bunnies are."

It was a short time before the little bunnel began to stir, resting against a soft pillow with a paw resting on his belly. As he opened his eyes he saw his other brother's room, lights off yet permeated heavily with the scent of the rabbits. His head was groggy... why was he here? He sat up, feeling the strain in his muscles as if he just had a workout, and as he looked over his nude, leaking body, he winced just a bit from a twinge of soreness near his groin. "W-what... happened?" His head was a jumbled mess, but he knew he'd been sent home... That he'd seen Hayden as well- and the two had... 
"Hayden?!"
He hopped, right out of bed, boundless energy returning even as stumbled a bit from the sudden movement. "Owww... Oh!" Eyes darting in the low light, his paws sifted about finally finding what he needed, a shirt to slip on so he'd be decent. He darted down the stairs whilst dressing himself, the shirt hanging enough to cover his groin, and then turned to see the empty kitchen for only a second before he sprinted the other way, so light on his feet that he nearly collided with the rabbit closing a door softly. 
"Daddy? Daddy! What's Hayden? He was here and I wanted to see him but now-"
“Shhh... calm down, not so loud.” 
"What? But I wanted to-" 
He looked up, seeing the red-haired rabbit's smile and a scrapbook tucked neatly under an arm, but soon found a finger to his lips, gently hushed. "He's asleep... He was very tired, after all. Now hurry up with me, we can eat and I have something to show you~" The smooth voice did little to dissuade those cheeks from puffing into a pant, but the boy nodded with a groan and trotted away to get food. ‘As stubborn as his mother...' He chuckled a bit as he followed making sure to take the time to show through the photos, the deep love the family of bunnies shared and how his love for Hayden would change him soon.
