The rattling of skateboard wheels filled the air as multiple cubs and teens rode their boards on the many ramps and slides of the skateboard park. Reluctantly erected by a hesitant city council, the freshly-made tracks were smooth and perfect for picking up speed, voices shouting when they cleared the air, made sick 360's, or stumbled and fell when they misjudged their tricks.

Up on the highest ramp, which was accessible by a narrow staircase, a small group of teens and a young cub were standing, looking down the 12-feet slope. The cub was a wolf, eyes hesitant as he looked down at the steep decline, feeling a twinge in his stomach. Right next to him stood his brother, 14 years old and full of punk, a green-coloured mohawk and a lip ring shouting to the world that he meant trouble. His black t-shirt adorned with a laughing red skull just accentuated that look.
"Awww look, lil' Lucas is scared of the big, bad ramp!" One of the other teen guffawed, jostling his elbow into the side of the teenage wolf, the latter grinning cruelly, looking down at the frightened kid who wasn't even allowed to be on this ramp due to the age limit proclaimed on a poster down at the bottom of the stairs. 
He sat his skateboard down, then stomped on its edge, making the other end fly up and hammer into the young wolf's groin. 
"Awww fuck Mark, that's cruel even for you!" Another teen laughed, as the little boy cried sharply and collapsed to his knees, clutching his groin. 
The teen wolf spun the board, stepped on its edge and it flipped, the youth adroitly jumping up on it, bending his knees, kicking out again, jumping as the skateboard flipped yet again, making a perfect landing, his well-muscled legs showing under the cutoff's of his shorts. 
"Lil' runt needs to be more aware of his surroundings, knowwhatI'msaying?" Mark said in a light tone, jumping off the board and kicking it up so that he could catch it. "If he ever wants to ride like us he needs to be focused and not just standing there being scared of heights like a toddler!" 

Lucas gasped and grumbled, eventually managing to get up again, though this time taking a few steps back, putting his back to the rail that encompassed the platform at the top of the ramp.
"F-Fuck you Mark!" He spat out, high--pitched voice wheezy from the pain in his gonads. 
"Eat shit, twerp!" Lucas said as he put his board down again, rolling on it to the very edge, ready to ride it down the steep ramp. 
"I almost had the 720 last time. This time I'll get it!" He said confidently to his friends, who oooh'd at his statement, eyes wide as they stepped near to see the action. Even Lucas braved to step a bit closer to the edge, fascinated by his brother's mastery of the skateboard, despite the casual cruelties he always inflicted on him, some weird sense of belonging making him endure his brother's bullying and his obnoxious friends. 

The teen wolf kicked off and whooshed down, wheels of his board rattling, and he cleared the opposite side, landing again, picking up more speed, whooping as he flew up several yards above the platform where Lucas was standing. Two passes more and he was now flying almost 4 yards up, way above the heads of his friends and little brother, making a few tricks in the air each time. Finally he shouted "here it comes!" As he flew high, rotating his body around again and then again, but he misjudged the timing and the angle, his flight having him rotate more towards the center of the very tall ramp. 
"Fuck!"
"Shit!"
"MARK!" Lucas shouted in fright as the teen hurtled towards the hard wood, arms extended to break the impact. 
A loud multi-crunch sound emanated from the impact, the teen wolf screaming in agony, Lucas looking away with bile in his throat as he saw bones sticking out. 

-----------------------

"...It's a very complicated set of fractures," a bored-sounding doctor said to Lucas' parents, his brother looking on bleary-eyed from his hospital bed, "right collar bone, both tibula, left elbow, right wrist, several of his fingers..." 
His voice droned on and Lucas noted how Mark began to cry softly as he was told he would be in a complicated cast for at least 3 months.

Next day, back home, Mark was sitting on the couch, watching a skateboarding competition while his mother fed him his dinner. Lucas had finished his by the dinner table and was sitting on the opposite side of the couch, eyeing his brother being fed, how his ears splayed backwards and his cheeks were reddened in humiliation. 
"Mom!" He said petulantly. "Do you have to feed me in front of Lucas?" 
"Hush dear, I fed you plenty of times when you were a babe, just as I did your brother. It's not like you can feed yourself, or do you want to eat it off your plate like a dog?" 
At that he grumbled, his upper body and arms a crisscross of casting, surgical steel buckles and nylon straps to keep it all in place. Lucas looked on as he was fed like a little baby and he grinned savagely, catching the eyes of his older brother who glowered but couldn't really say anything with their mother around. 
"Now. Before bed you need a shower. Do you want me or your dad to do it?" 
"WHAT??" Mark shouted incredulously, shifting about in the couch.
"You can't go to bed without a proper shower," she leaned in and tried to whisper, but Lucas heard it all, "you kind of stink Mark." 
"Mom! Ew! No! You can't wash me, that's to embarrassing!" 
"What, you want you brother to do it?" 
"I won't mind!" Lucas piped up, both his mom and his brother looking at him with wide eyes. Then something shifted on Mark's face.
"Deal!" 
"I'm not so sure about that..." Their mom said, her tone strange. "It doesn't seem proper. Why not have your parents do it? It's been years since I had you in that little yellow tub and washed your tushy for you." 
"MOM! Seriously! That's way too much!" The punky teen said, lips puckering as if he had tasted something sour, ring glinting in the light, a heavy blush creeping up on his face.

She took a step back, putting her paws on her hips, looking from one son to the other, Mark not meeting her gaze, Lucas smiling brightly in a cub-like manner. 
"Okay mister too-good-to-be-cared-for-by-his-mom. But if Lucas doesn't do a proper job and wash out all the nooks and crannys, then I will do it for you instead!" 
"Ewwww! F- I mean no thanks, I'm sure my brother can handle that."
At that the woman took the empty plate out to the kitchen, leaving the young wolves alone.
"Hey Lucas, come over here man." Mark sort of whispered, jerking his head in a 'come here' motion. The 10 year old scooted closer and the teen whispered even lower, eyes constantly darting towards the door where their mother had left. "Listen, my shorts got bloody and all, but haven't been put in the washer yet, or else I would know. Reason being there's a pack of smokes there. Go fetch it for me and don't forget the lighter!" 
Lucas nodded, ears flapping about as he felt naughty about complying, but he wanted to help his brother out, even if it was for a bad thing. He knew his big brother smoked and he also knew his parents would fly off the handle if they found out.   

It was kind of amazing they hadn't found the pack, as it bulged out the pocket of the blood-stained shorts that were in a little plastic bag, Mark's t-shirt too torn up to salvage, the washer running even now with a heavy load of towels and sheets.
"Just in time..." Lucas whispered to himself, ears splaying back and forth, listening to any sounds of his parents getting near.
As he got back, Mark's eyes lighted up in a happy smile, his teeth showing as the smaller wolf waved the pack of cigs about, before he looked quickly to the door, mouthing "put them away" as footsteps approached. 
"Now boys, it's getting close to bedtime, and you really need that shower Mark." She looked over at her younger son. "This first time I will show you how to put the protective plastic over his body so the water doesn't mess up his casts. Yes that means you will have to strip to your undies for me Mark!" Her tone boded no reprieve and the wolf would have slumped his shoulders if he was able to. Still, his eyes were mainly on his little brother and how his back pocket bulged from the pack of cigarettes, a little extra bulge on top showing the indentation of the lighter. 

"So you get it over his head like this, and tie this strip and that strip here..." The instructions were fairly complex, due to the vastness of the teen wolf's injuries and he stood there, shivering a little almost nude as his mom walked from side to side, adjusting the massive piece of plastic that would keep his casts safe from going soddy and moldy with water. 
"Okay, I will leave you boys to it, and remember Mark, Lucas has to clean out all the nook and crannies. If you become stinky, either I or your dad will have to do it instead!"
"Fine mom, jeez, you don't have to spell it out!" 
"remember to pull the foreskin back!" She called out in a singsong voice as she shut the door, and Mark's tail went under his legs in embarrassment, a heavy blush on his cheeks. 
"Of course I will. Everyone know you have to do that.." Lucas said, cocking his head quizzically, the young cub not at all surprised. He had heard 'every nook and cranny' and fully understood it, merely wanting to help his big bro out as a favour. 
"Seriously! You're all just... UGH!" Mark shook his head, then looked at the door. "Hey, Lucas, lock the door will ya?"  
Somewhat understanding his big brother's mood, the small wolf headed over and the lock clacked as he operated it, turning back to face the teen wolf. 
"Gotta get undressed as well I guess.." He muttered, quickly putting away his dirty clothes, then heading over to Mark fully nude, grabbing at his underwear.
"Hey, get your paws off me, twerp!" The teen took a stumbling step backwards and almost tripped, yelping as his back hit the tile wall with a thud. He whimpered, not wanting to cry out in front of his brother, but the cast on his shoulder took some of the impact and he shivered from the pain resonating through his broken bones. 
"Gotta get your undies off, dumbass!" Lucas demanded, growing annoyed by his big brother's antics. "Can't shower with your undies on now can you? Might as well keep your socks on too!" 
At that he looked down at the teen wolf's pretty dirty socks and almost cringed, knowing he would have to pull them off by himself. 
"I guess you're right." Mark said, finally coming around, wincing as he stepped forward and the cast shifted about. 

When the socks were off and Lucas pulled at the underwear a second time, he was surprised by the soft length that plopped out. 
"Wow Mark, you've gotten really big down there!" He said, almost reaching out like a curious cub, before the older wolf shuffled backwards, managing to shimmy out of the undies by the power of his legs. "And all that hair wow!"
"Don't stare at it like that. Seriously." He said with a scowl as he entered the shower stall, shaking his head. 
The sound of water filled the cramped space and soon little Lucas was working on his brother's pelt, lathering it in with soap, not even hesitating to grasp the soft length that jutted from his crotch. 
"H-Hey!" Mark yelped, stepping back, hitting tile.
"Gotta get under the foreskin, you know that!" Lucas said, a determined look to his face as he grasped the humanoid cock, pulling the skin back, Mark just standing there mortified as the exploring and soap-covered fingers rubbed all over his glans and down his shaft. He gulped as he hardened up, feeling shivers in his stomach from the wrongness of it all. 
Then again, at least it wasn't his mom doing this! 
"Wow, you are even bigger when you're hard. This is so cool!" Lucas said excitedly, pumping it a few times before an angry shout from the teen stopped him. 
"Stop that. You know that's a private place!" Mark said with a heavy blush, his cock throbbing in the air, some 5 inches of humanoid meat pulsing with his heartbeat.
"Okay... Still need to rinse it though." The 10-year-old said mischievously, taking the shower head and directing at his brother's crotch, the hot water impacting his member making it wobble and spasm in the air. The teen tried turning his body, but Lucas just laughed and pointed the stream under his tail, making him squeal and turn about, only for his erection to get another involuntary rinse. Lucas laughed, his high-pitched laughter filling the room as he made his older brother squirm and turn about for a while until he turned the nozzle away and put it into place.
"Okay okay, I'm done teasing you, still need to clean your headfur and all that. As well as your butt!" 

One humiliating and very thorough shower later, the two boys were toweling off when the door handle creaked, lock holding firm. 
Mark instantly turned away, wet tail bushing underneath to hide himself, while Lucas stood with his paws at his hips, unabashed by his nudity. 
"Boys, mom and I are heading to the bridge club as usual," their dad said, the usual Friday-evening pastime forgotten by the cubs in all the hubbub, "don't make any trouble. I know that you would normally be watching Lucas, but this time I guess it's Mark who has to be babysat!"
"I'm fine!"
"I'll take care of him!" 
"Alright kids, love ya." 
"Bye.."
"See you dad!" 

At that, Lucas turned, towel in paw, and brusquely pushed it into his teen brother's crotch, the older wolf grunting as the firm toweling soon made him hard again. 
"S-Stop it!" 
"Nu-uh!" At that Lucas' paw flew out, smacking the throbbing cock, the teen shouting as he jumped back.
"What was that for??" 
"The skateboard at the park. Although I really owe you more for that.."
"Fuck off twerp!" 
"I think I have to punch your nuts to get even.." Lucas said, suddenly pensive, reliving all the recent times his brother had bullied him. 
"Fuck. Off." Mark said, taking a step back as if to kick him.
"DAD! HEY DAD!!!" Lucas screamed at the top of his lungs, reaching down to rummage at his shorts, pulling out the cigarettes he had procured for his brother. 
"Fuck. No. Don't do that. Don't say it." Mark whispered hoarsely. 
"Then let me punch you in the nuts!" 
Footsteps came near, the door rattled as it was knocked and the handle was rattled a few times.
"Boys?" 
"Okay okay okay!" Mark was all hunched over, whispering through his teeth. Lucas turned away with a chipper smile.
"We just wanted to say we love you, dad! Have a good evening!" 
There was a pause outside the door, then a mutter, then the man's voice came through the wood. "You too, guys, love you too!" 
"Love you dad..." Mark said, trying his best to sound like he meant it as he listened to the footsteps going away.

Then Lucas turned to face the teen. "Spread your legs!" 
The teen wolf mouthed the word 'fuck' and then did as ordered, swaying a little as he didn't have his arms for balance. 
"Don't go so harhhhhhhOOOOOOFFFFFFFFFFFFFF!" 
A solid uppercut impacted his stones, the younger wolf hitting with surprising precision and power, causing the teen the collapse to his knees and hunch over, the casts and straps holding it creaking as he tried to reach for his bruised nutsack. 
He hurked, spit flowing from his open mouth as he tried to catch his breath, the immense pain almost making him vomit, breaths hard to take. 
"Now we're even!" Lucas said, the boycub feeling a bit more powerful, thinking back to all the other times his brother had treated him cruelly. Mark's vision was blurry, but as he got back to reality, his eyes narrowed dangerously as they focused in on his little brother. He vowed to get payback, but first he needed his help.
"Hey Lucas, now that they are gone, I need you to help me light up a cig in the backyard..." He said, grimacing as he got to his legs, frizzy-haired pouch aching as it dangled. 

"You can't be serious, why'd you force me out here in the nude?"
"Relax Mark, no one can see due to the fences." Lucas said, looking about the lush backyard, well-mowed grass and flowerbeds and shrubbery. 
They were on the patio, and the cub had given the teen a cigarette. 
"Hurry up and light it, got mad cravings bro!" Mark said, leaning down, but Lucas stepped back, dangling the lighter in front of his helpless brother. 
"Spread your legs again. I owe you a bunch of nutpunches!" 
"What??" 
"Can't remember? Last Sunday you hit my arm so that it hurt for an hour, Saturday you kicked my crotch from behind in front of your stupid friends, Friday it was at school and you kneed me, Wednesday on the way home from school where you reached and punched me there while mom and dad where busy ordering at the drivethru.,," Lucas used the lighter to count on his fingers. 
"Fuck, okay okay okay," Mark said, spreading his legs a little. 
"Bend over the table there, spread your legs properly! You'll just hunch up and then I won't be able to hit!" 
The teen wolf grumbled as he did as ordered, laying his body over the wooden table, spreading his legs out, opening himself up to his brother's attack.
*WHAMP!* 
A kick! Right on the balls. Mark collapsed, wheezing and coughing, tears falling from his eyes. He wanted to roll around but all the casts and straps prevented him from doing so, instead curling up his legs like a helpless tortoise. 
"Here," Lucas said, bending down to light the cigarette which was somehow still in the teen's mouth, Mark drawing in the smoke but not really getting much out of it due to the pain in his gonads. 
"I'll fucking murder you..." The teen growled weakly, but Lucas just chittered, knowing his big brother would be helpless for months.

A week later, several showers later, many punches and kicks and knees to his crotch later, Mark was on the couch daydreaming about Sandra with the big rack from his class. He imagined her sucking his dick and he hardened fully, the member throbbing against his shorts pitching an obvious tent. 
Lucas was sitting next to him, eyes glued to the show they were watching, but he noticed the pulsing in his brother's shorts and turned to face him with a grin. "You're hard Mark." He said in a teasing tone, rummaging with his pocket, fetching out his phone which his punk brother had unlocked the parental control on. 
The cub had went to PawHub a few times out of curiosity, feeling a few tingles, but nothing more, and he just picked a vid at random, showing it to the teen, horny moans filling the room. 
Their parents were out, so there was no reason to be subtle about it, and he pushed the volume button up and then showed the scene to his brother. 
Mark blushed and gulped, his hardness throbbing as he watched the pornstar being railed, then meep'd out Lucas put a finger on the developing wet stain on his shorts. 
"Are you peeing yourself?" He asked quizzically, sniffing his finger before wiping it on Mark's right cast.
"I-It's called precum.." The teen said, huffing as his eyes were focused on the wet pussy taking the big cock on repeat, his own member throbbing hard, but untended to. He hadn't been able to jerk off obviously, and had tried humping his pillow like a cub to no avail, the casts and all the straps making it impossible for him to get a good angle, and especially not allowing him to pick up speed.
"Precum?" Lucas turned the phone away and tapped at the screen, his eyes lighting up as he searched for the word. "Oh that means you're super horny!" He tapped around on the screen and played another video. 
Mark cringed as his little brother showed him a hardcore threesome, "Barely Legal Wolfress Railed", the young woman gurgling around a cock down her throat, her ass being destroyed by an older man twice her age. His cock liked it though, throbbing under his shorts, more pre staining through. 
Meanwhile Lucas just sat there, observing it all, feeling a little tingle in his stomach but nothing more, eyes simply curiously swallowing up how his brother's breathing became more staggered, how he blushed, how he throbbed. 

Finally Mark snapped. He needed release so bad he almost wanted to cry. 
"Lucas, i really need you to help me out. Can you like.. Jerk me off?" 
"What you mean touch you? You said that wasn't proper, that it was private!" The 10-year-old cocked his head.
"Yeah. Well. Uhh. I can't do it myself you know and..." 
"Oh look, he's peeing all over her! Wait, why is it white?" 
"Dude that's cum. Semen you know? That's what I want you to help me get out?" 
"Ohh! That's stored in the testicles, we learned that in school!" 
"Yeah... Lucas, seriously, won't you please help me out?" Mark gulped as a new vid began to autoplay, his cock feeling harder and harder.
"If you wanna pee white stuff we are going to the bathroom!" 

Inside the white-tiled space, Lucas helped the teen get undressed, curiously eyeing the throbbing cock which hadn't gone down and how slick and shiny it looked. Mark looked away as the cub reached for his member, then gasped as the cub squeezed it and stroked it a few times, more precum oozing out, making the foreskin slide even better.
"Ohhh, you are really horny!" The cub said in his high-pitched voice, feeling how his brother's cock surged in his grasp, then he got a devious idea and put his other paw on the testicles, pulling them down rather harshly.
"Ow! Fuck Luca-" Mark then yelped as the cub let go and instead hammered a punch in, keeping his grip on the teen's five-inch member. He then let go, allowing Mark to bend over and wheeze from the impact. 
"Bend over the sink. I think I owe you at least 10 punches to your balls and I don't want you to cover up!" 
Mark just shook his head, but his horny mind overcame his hesitation, his needy cock spasming even as surges of pain radiated from his nutsack. He did as ordered, shivering as his stomach touched the cool porcelain.
"Spread your legs!" 

Lucas smiled grimly as his older brother shivered and let his footpaws slide over the floor, his tail bushing up, creeping low on its own accord. Still, it left the teen exposed, and the cub grabbed the tail, bending it upwards, focusing in on his brother's heavy-hanging nutsack.
*WHAMP!*
*WHOMP!*
"One. Two. Three." At the fourth strike Mark wailed, howling like he was scalded, but he kept his position. "Five. Six. Seven." The teen sobbed, his legs splaying further apart as he weakened. "Eight. Nine. TEN!"
Lucas shouted the last number, hitting his big brother as hard as he could, and the teen croaked and collapsed to the floor, wiggling about like a worm, casts creaking as he tried in vain to reach down and touch his swollen nuts. The cub noticed that his brother's cock was still hard, the head swollen and purplish with arousal, even more precum dribbling down the shaft. He cocked his head curiously, wondering how the teen could still be horny when hurting so much, but his smile was all teeth as he re-lived the many, many times his brother had bullied him, the payback sweet. 
Mark was crying openly, sobbing from the deep pain radiating from his gonads, eyes closed, but then he gasped as he felt his brother's soft paw on his cock, stroking his meat gently, the pleasure soon overcoming the pain and his crying stopped, replaced by low moans. 
"If you are going to pee semen like the man in the video, you need to do it into the toilet!" Lucas said then, and Mark grumbled as the paw was removed from his needy prick. He shuffled around awkwardly, managing to get on his knees, and he crawled over to the toilet, cock spasming just above the seat.
Lucas stepped in then and grabbed his member again, stroking it.
"Grab it a bit harder..." Mark instructed, and the cub did so, noting how the teen's face became blissful, eyes closing in pleasure as the strokes became more firm. 
"Rub it a bit faster..." Mark whispered, ears splaying back as he fought against the wrong-bad incestous feeling of his baby brother touching his junk. He then whined out as the cub stroked him almost like he himself would, long and hard and fast strokes that had his precum-slickened foreskin slide over his dickhead again and again. 

Lucas noted how his brother's breathing grew more laboured, how he squirmed, how he gasped, his eyes scrunched up in pleasure and then he got a most horrible, cruel idea. 
He looked at the lid of the toilet, then at the height of his brother's crotch, and in a dual motion he let off the cock, grabbed the swollen testicles, lifted them up on the seat and brought the lid down, putting a firm paw on it and jumping up on it, sitting his butt down with a *clang* as porcelain almost met porcelain, Mark's nutsack trapped.
The teen howled in pain from the agonizing pressure of his brother's full weight compressing his stones, knees weakly sliding on tile, but the skin just stretched painfully and he had to lean forward to avoid tearing his pouch off. 
Lucas then grabbed the cock, which had spurted several thick globs of precum from the heavy pressure, and he began masturbating his brother again, doing it properly with hard and fast strokes, Mark crying and begging for him to get off the seat which his was crushing his gonads to the point where he thought they would pop. 

Despite the pain, the pleasure radiating from his cock had him close to climax again, and he whimpered and moaned as he finally shot his load, the eruption of semen delayed by the heavy crush, before it spurted out with immense pressure, painting the 10-year-old with his brother's seed. 
"Ewwwww!" Lucas shouted, hurriedly getting off, porcelain clanging as he shifted his weight, Mark howling in pain before his nuts were released and he dropped to the floor, more ropes of cum flying everywhere as the pressure was finally let off.
The cub looked at the cum all over his body and paw, even feeling a wet splotch on his face, and he threw off his clothes, heading to the shover, letting his big brother writhe in agony on the tiled floor. 

-------------------------------------

Lucas was surprised that his brother asked for another jerk-off session only a few days later, the 14-year-old wolf full of hormones and horniness, even braving the pain of the 10 knees to the balls the preteen demanded in return. 

This time he didn't trap him under the toilet seat, although 3 weeks later he did, bouncing his butt on the porcelain while Mark screamed in agony even as he climaxed, the cub smart enough to angle the cock towards his older brother so that he didn't get painted white. This also gave him a chance to properly wash the front of his belt afterwards, groping the slightly-deformed nuts, Mark whining in the shower as his little brother massaged some blood back into them again. 
It became common for the teen to give his little brother a certain look, and they would head off into different places in the house or yard, even when their parents were home. 

Lucas kind of dreaded when it was time for the cast to come off, his older brother would surely take a hefty revenge for all his antics. When it was time to go to the hospital he was sort of shivering, when they got home the weird silence between the two was awkward, when the weekend came and his parents would go to their bridge club, the young wolf had a stone in his stomach, wondering in which ways his brother would torment him. 
They were sitting on the couch, watching some action movie, Lucas constantly looking at his older brother, worried how the punky teen would treat him once he was sure their parents had left, but nothing happened. 
The teen was snarky and demanding, lording over his little brother as usual, but not physically bothering him except for tickling him a little, enjoying how his fingers could move about again, Lucas squealing at the gentle play. 

After the movie finished, his brother squirmed a bit in his seat, looking at Lucas in a strange way, his shorts tenting up. 
"Time for bed!" He said, getting Lucas to brush his teeth and all that, shutting the door to the  cub's room and heading to his own. 
An hour passed and the young wolf was quite confused, although he simply passed some time playing on his handheld console, before his door was knocked on. Mark came in, looking strangely sheepish, fully naked, uncut cock hard. 
"Lucas, uhhh...." The older wolf got on his knees, putting his paws behind his back. "Please jerk me off. It doesn't feel right when I do it myself." 
The young cub got off his bed, looking at his brother's engorged member, a bead of precum dribbling out. He cocked his head quizzically, not really knowing what to do. 
"I-It's okay if you want to kick my balls first!" Mark said with a needy whine, blushing heavily, spreading his knees out, paws still behind his back. 
"How many times is fair?" Lucas said, stepping close, then sending his foot away, the impact hard enough to shove the junk around but not damage it, something he had gotten a supreme feel for. 
Mark grunted, barely bending forward, cock shooting a string of pre out. 
"Ah, ah, as many you want!" He gasped, ears splaying backwards, cock throbbing harder than ever. 

Lucas gave him another kick, with the other foot, letting it be extended, pushing up against his brother's body, feeling how the nutsack felt plump and his brother's cock throbbed. 

"20 seems like a good number. These don't count, they  were just for warming up!" 

Loud smacks and masochistic whines filled the cub's bedroom as Lucas went to town on his brother's  balls.
