“Cannonball!” Aaron shouted as he jumped off the roof. With his arms wrapped around his legs and his tail tucked in, he landed in his family’s above-ground pool with a tremendous splash. Water sloshed over the sides, splashing onto the lounge chairs surrounding the pool, as well a coyote sitting in one of them—Aaron’s older brother, Markus. Markus, annoyed about his wet shirt and fur, grimaced as his little brother came up and gasped for air.

“How was that one?” Aaron asked. The little coyote was 11, and and still too short to reach the bottom of the pool with his feet. He waded in the pool, looking to his older brother for approval.

Markus padded the pockets of his shorts to see if his phone got wet. Luckily, the water only splashed his upper body, his beanie and his t-shirt. “You know you’re not supposed to be jumping off the roof,” he said.

“You won’t tell mom,” Aaron said as-a-matter-of-factly, climbing out of the pool. It was a warm spring Friday, and school had just gotten out. Despite it being basically the weekend, their mom was working late, again, and Markus was left with looking after his younger brother at their house. Markus dragged the lounge chair a few feet farther from the pool. Aaron was out of the pool and already on his way to the roof again, using a trashcan and then their backyard shed to easily climb up.

Markus sat back down and looked at his brother as he climbed. The little coyote, though having lost a lot of his cub fat in the past couple years, was still a bit chubby, but just starting to hit a growth spurt. His gray and tan fur was very similar to Markus’s, but his little brother’s ears were noticeably more rounded, where his own (sticking out of two holes in his gray beanie) were very triangular. Markus couldn’t help but stare at his little brother’s swim shorts. They were a blue floral pattern, hand-me-downs that were far too small for Markus, but also just slightly too big for Aaron. Aaron owned a pair of speedos for his swimming classes, but for some reason the little coyote preferred to wear his brother’s former swim trunks whenever he played in their pool. The hole in the back for the tail was just wide enough to see a bit of Aaron’s round rump underneath, and Markus noticed the strings at the front of the suit had become untied... He shook his head, and turned his attention to his phone, where he was playing some free game he just downloaded.

“Watch this, Marky!” Aaron shouted as he launched off the roof again. But Markus said nothing, keeping his eyes on his phone as his brother landed in the pool with another splash. This time, he was seated far enough away that no water sprayed on him. He heard his brother come up for air and say, “Aw, you didn’t look!”

“Yeah, you see one, you seen them all,” Markus grumbled, trying to concentrate on the colorful numbers flashing on his phone screen, but it was difficult. He heard the swishing of water as his little brother climbed out of the pool, and then a few seconds later a chuckle.

“Oh, haha.”

Markus allowed a glance up, but then full-on gawked when he saw what happened. Aaron had climbed out of the pool and was standing at the top step of the ladder, totally out of the water. He was completely naked, the full front of his body facing toward Markus. The swim suit had come undone and was floating somewhere back in the pool. Markus stared at his brother’s white furred belly, then focused on the little coyote’s member. Even though Aaron had just been swimming for nearly half an hour, it was a warm, sunny day, and his cock hung freely with his balls only a little shrunken, all of it dripping wet right there in the open.

Markus stared wide-eyed in silence for a few seconds at his brother’s pink little penis and light-tan furred ballsack before finally tearing his gaze away. “Oh for god’s sake, put your suit back on,” Markus nearly yelled with audible anger in his voice, his eyes cast down on the grass.

“S-sorry Markus,” Aaron said, his ears flattened down. He dropped back in the pool, his lower body out of view. Why was his big brother so angry? It was an honest mistake.

Markus got up and headed back to the house. “Pool time’s over, dry off and come inside,” he said curtly, opening the glass slide door, not evening glancing at his little sibling. He practically slammed the door closed, leaving Aaron wading alone in the pool. Aaron felt tears well up in his eyes, and scrunched up his face as he held them back. Markus shouldn’t have yelled at him like that. It was an honest mistake, after all.

After sliding his suit back on, Aaron got out and toweled off. His brother had been acting weird lately. Well, he’d been acting weird for the past couple years, but he was acting especially weird nowadays. He was getting angry for no reason, and hardly even talked to Aaron or looked at him in the eye. Markus was a whole 5 years older, but Aaron could remember when they were both little and used to play together for hours on end. Then sometime when Markus started high school, he just kinda... checked out. Aaron rubbed his face with his towel, convincing himself his eyes stung from pool chlorine and not from tears. He wished it could be like the old days, and he would do anything to get his brother to love him again.

---

Their mom came home late like usual, with a rotisserie chicken she bought from the store for them to eat. During dinner, Aaron talked hurriedly about what happened at school that day, about how a kid at his elementary school, a beaver named Cy, dumped an entire jar of glitter on another student during arts and crafts. Their mother listened interestedly, obviously tired from a week of work, but trying her best to follow all the details of Aaron’s story. Meanwhile, Markus said almost nothing, and even left before they had dessert.

After doing their nightly bathroom routines, the three coyotes headed to their respective rooms. It was Friday night and only 11 o’clock, but they were all pretty tired. “Goodnight, boys!” their mom yelled down the hallway. Aaron yelled back, and from behind his brother’s closed door, he could also hear Markus shout a muffled “Goodnight.” Aaron could remember one time a couple weeks ago, he opened his brother’s door just to see what Markus did alone in his room all day. His older brother was sitting on his bed with his computer, and Aaron couldn’t see what Markus was looking at, but the little coyote got yelled at and kicked out of the room instantly. Since then, he’s hardly been in Markus’s room at all.

It was a pretty warm night and too hot to wear his pajamas, so Aaron only wore his blue underwear to bed. He flicked off his light switch, then ran to his bed and hopped under his one blanket. After a few minutes of playing what happened that day in his head—the beaver spilling the glitter, his brother yelling at him in the pool—Aaron drifted off to sleep.

While Markus is a pretty light sleeper, and their mother is almost impossible to wake when she conks out, Aaron is somewhere in the middle. He didn’t hear his bedroom door creak as it opened, and only stirred when someone walked across the room, their paw pads shuffling quietly on the carpet. He finally woke when the bed slightly shook, groggily turning his head to look. It was rather dark in the room, but he had already been asleep for a few hours, so his eyes were adjusted enough to see what was happening.

Aaron had been sleeping on his left side facing away from the door, and his brother was lying right behind him. Markus was in his boxers, almost close enough to be touching Aaron’s back. The little coyote must have kicked his sheet off sometime during the night, as it was crumpled up at the bottom of the bed. The two brothers were now lying together, Aaron the little spoon and Markus the big spoon, both wearing next to nothing, their fur just barely bristling one another.

Aaron wasn’t scared, but he was confused, and just about to ask his brother what he was doing when he saw Markus’s face. Markus was staring into Aaron’s eyes. Not menacingly, not angrily, but relaxed—the first time Aaron saw his brother like that in years. With every deep inhale, Markus slowly closed his eyes, opening his lids with each exhale. Aaron realized his brother was smelling the back of his neck, making him even more confused.

Markus draped his right arm over Aaron, rubbing his hands over his brother’s fur. He ran his fingers through the young coyote’s little chest tuft and pulled him closer, closing the half-inch gap remaining. Aaron’s foot-long tail was pushed upwards, pressed between the two. The brothers’ bodies were now touching, and even looking over his shoulder, Aaron couldn’t see what Markus was doing. But he could feel it. Markus was rubbing his pelvis against Aaron’s lower back, and through his underwear Aaron could feel something poking him in the butt.

His confusion finally gave way to fear as Markus continued to grind his waist harder against Aaron’s little butt. Keeping his right arm tight on Aaron’s chest to rub his chest and nipples, Markus slipped his left arm under the boy, placing it on the front of his underwear. This was enough, Aaron had to say something.

“Markus, what... what are you doing?” he asked, for some reason finding it hard to catch his breath.

But all Markus said was “Shhhhhh,” continuing to rub and grind on his little brother. The thing poking him the back was getting, well, pokier, and Aaron’s whole body was tingling, especially the little coyote’s private parts. This was all so weird to Aaron, and he didn’t know these new sensations he was feeling. He couldn’t tell if they were good or bad, but it was all happening so fast he was sure he wanted it to stop.

“Stop, no... ohhh.” Aaron gasped as Markus slipped his left hand into his underwear and started playing with his little brother’s balls. He used his thumb and forefinger to massage the furry ballsack, then cupping lightly tugged at Aaron’s testicles. The right hand also then sunk into the little coyote’s blue underwear, gripping the small humanoid penis. Aaron could feel his dick getting warm and hard, blood rushing through his head and his genitals. With this strange pleasure coursing through his body, he found it hard to think or say anything, but he did finally realize what was at his back. Markus’s dick was poking him in the butt!

Aaron, still convinced that he wanted this to stop, tried speaking, but all that came out was grunts and half-words. Both his own and his brother’s cocks were as hard as they would get, but Aaron could still feel something building. He wasn’t sure where it was coming from, whether it was his head or his loins, but he could definitely feel something growing.

Markus, who was building up speed and intensity this entire time, was now pulling at Aaron’s skinny dick, hard. It hurt, he was gripping it so tight, but that feeling inside was so good it almost made everything else numb. Markus was fully tugging, the cloth of Aaron’s underwear making a soft fap sound with each quick jerk of his right hand, while his left continued to massage Aaron’s balls.

Then, suddenly, Markus pulled his hands out of the underwear and sat up on his knees. Aaron was dizzy, and only could make a weak “Ehhhh” noise as Markus rushed to yank the underwear down Aaron’s legs, pushing the little coyote’s tail out the hole in the back. Lifting a leg up, Markus also quickly removed his boxers, revealing his own manhood. In the dark, it was hard to see any color, but Aaron could clearly make out his brother’s own genitals as he was kneeling on the bed. His penis was rock hard, pointing almost straight up. It was just an inch or so from his belly button, and had a good girth about it too. It was definitely bigger than his own, making sense as Markus was several years older. His balls were also larger, and in the hot, dark room hung considerably lower than his own did. The fur on the sack and around the base of the penis was also longer and thicker, unlike his own soft puppy fur.

Now that they were both entirely naked, Aaron felt more confused than ever. Wasn’t his brother angry at him earlier because he didn’t have his pants on? None of what was happening made sense to him. Looking up from the big coyote’s groin, Aaron saw his brother’s face. His whole body was beaded with sweat, and through the fur he could tell Markus’s skin looked darker than usual, his face flushed with blood. His eyes were definitely no longer relaxed. They were intense, as if Markus had a goal in mind he needed to accomplish that night.

Markus spread his little brother’s knees and stuck his face in his crotch, the tip of his snout just barely grazing the area between the balls and the base of the penis. He inhaled three, four, five breaths, deeper each time. “Markus...” Aaron whimpered weakly. Then Markus went down on Aaron, sticking the little cock easily in his mouth.

Aaron gasped loudly, even louder than when Markus first put his hands in his underwear. That building feeling returned stronger than before. Aaron’s dick probably only went halfway into Markus’s mouth, and he was tonguing it like crazy. Keeping the cock in his maw, Markus rubbed his tongue along the underside of it, with enough length at the end of his tongue to just lick the top of Aaron’s ballsack.

He couldn’t think or talk. He could barely even control his own movements, Aaron’s whole body seemed to be coursing with electricity. Aaron tossed and squirmed, using the last of his control to place his hands on his brother’s muzzle. Aaron was sure this feeling was going to end soon, but he wasn’t sure how or with what.

Aaron’s pelvis involuntarily lurched forward, humping Markus’s face and bring his cock just a little farther into his mouth. It’s like a firework went off behind Aaron’s eyes. He felt his cock spasm and pulse, bringing something deep within him and shooting it into Markus’s mouth. Somewhere in his mind Aaron wondered what if anything was coming out of his penis. He was sure it couldn’t be pee, but it all felt so intense any coherent thought instantly evaporated.

Aaron tensed up one final time as he rode that wave of pleasure, and fell back on his bed, his arms limp at his side. He was panting, and his whole body was so soaked with sweat his bed sheets were also wet. Markus lapped his tongue once more, and audibly popped open his jaw to let his little brother’s hard, wet dick fall down. He shuffled backwards, stepping onto the floor at the edge of the bed. Markus then grabbed Aaron’s legs and dragged his brother, still on his back, toward him until his knees draped over the edge of the bed. Aaron was too drained to do anything about it.

Aaron craned his neck up and once again saw his brother’s cock. It was still hard and throbbing with every heartbeat, and he could see at the tip there was a bead of fluid gathering. Just like how he first rubbed Aaron’s cock, Markus started quickly stroking his own member, gritting his teeth and making a low growling sound. From this angle, Aaron could clearly see the difference in their body types. Though Aaron had a bit of belly fat, Markus was pretty lean. He wasn’t super athletic or muscly, but he had an all-over good body and a decent-looking canine face. The teenage coyote’s knees cracked as he bent to the carpet and lowered his body, putting both his and his brother’s genitals at the same level.

Exhausted like he never had been before, Aaron flopped his head back on the bed and closed his eyes. But only for a second, as he felt something poke his rump. His eyes shot open and he quickly sat back up. His brother had brought his large dick right under Aaron’s ballsack and was thrusting at his tail hole. Despite everything he went through that night, that feeling was perhaps the strangest, something trying to enter his asshole. Aaron didn’t like the idea of something so intrusive, and involuntarily clenched his butt and whimpered. But Markus once again prodded the tip of his penis against Aaron’s tail hole and said, “It’s okay.” His voice was quiet and shaky, but they were the first words he spoke all night to Aaron. “I won’t put the whole thing in...”

The little coyote let out another whimper as his brother finally did penetrate the ring. Aaron scrunched his eyes shut and gripped the sheets on his bed. But Markus kept his word, and slowly went in only until the glans of his head were just barely past the entrance. Aaron’s butt was so tight around Markus that he instantly let out a long groan of pleasure. Perhaps a bit too loud, but he knew his mother, asleep on the other side of the house, couldn’t possibly have heard it.

Markus didn’t go any farther into Aaron’s butt, but used his right hand to stroke the remaining inches of his cock outside. So far this was definitely Aaron’s least favorite part, but he wondered if Markus was about to feel that incredible pleasure he just experienced. Markus stroked faster and faster, his hand slamming into Aaron’s cheeks with a slapping sound. It was more uncomfortable for Aaron than painful, but he still shoved his paw in his mouth and bit down to keep himself from screaming. Markus was gritting his teeth hard, and a low growl started to grow in his throat.

Suddenly stopping his stroking, Markus’s face then entirely relaxed, and he let out a quiet breath. Aaron felt Markus’s dick twitch on its own, pumping something warm up inside him and coating his inner walls. A couple more pulses filled Aaron’s ass with liquid, but a couple seconds in Markus pulled out and Aaron’s hole automatically clenched shut again. At the edge of the bed, Markus was rhythmically pulling on his dick, flinging strings of white fluid into the air. The hot stuff landed on Aaron’s bed, his chest, his own little cock and balls. Markus kneeled there for several seconds, firing load after load from his dick onto Aaron’s fur. A strange scent filled the air, a smell Aaron didn’t recognize. He felt something warm dribble from his anus, which was still a little weak from the penetration. Finally, Markus’s cock stopped pulsing, and with his eyes closed he slowly rose to his feet.

He opened his eyes and observed the scene he had created. Aaron was a mess, covered in his own sibling’s seed, and his then-limp dick still glistening wet with saliva. Aaron had no sense of how much time had passed since Markus woke him up. At first, he wanted to know what Markus was doing, what exactly was going on, but now he was too exhausted and drained to care much about anything.

Markus walked to Aaron’s hamper and grabbed some of his brother’s dirty clothes, socks and underwear and the like. He then proceeded to wipe down Aaron’s body and bed, trying to get as much of the cum as he can. Stains on little kids’ clothes aren’t a mystery, and he was sure his mother wouldn’t ask questions... as long as neither of them said anything.

After placing the dirty clothes back in the hamper, he put Aaron’s and his own underwear back on, the little coyote not putting up any resistance. He gently picked Aaron up, moving him back to the top of the bed and placing his head on his pillow. Markus covered him with the thin blanket, pausing, trying to think of something to say. But he couldn’t think of anything. Both of them were left speechless after what had just taken place, Aaron feeling confused, Markus guilty.

The room was quiet, the silence almost deafening after all the sounds the two of them just made. Markus stood over his brother. A few minutes had already passed since he came but his penis was still half-erect, making the lump in his boxers visible. Aaron was lying under his blanket eyes closed, breathing quietly with his mouth open, but Markus was sure he wasn’t asleep yet. Just as he was about to go, Markus heard his brother say with his eyes still closed, “Do you hate me?”

The words almost stung Markus, cutting him deep like a knife. If only Aaron knew... but Markus couldn’t think of a way to explain what had just happened, what he himself was responsible for. What he just did was, what, illegal? Immoral? Whatever happens tomorrow he will take responsibility for. But Markus in all his guilt couldn’t see it as an act of hate against his little brother.

So all that Markus whispered was, “No.” He then headed back to his room, quietly closing Aaron’s door behind him.
