“See you in two weeks!” Jeremy called to his parents as they pulled out of the drive. The feline boy,  sporting black and white fur, was twelve years old and eager to have some semblance of freedom. His household was a strict place, and strictness was often unwelcome for a growing boy.
“What's the plan now, kiddo?”
Jeremy turned, scowling at the use of 'kiddo'. The question had come from a brown tabby in his early twenties. His uncle, Mike. “Dunno. Play video games, I guess.”
“Ah, I miss those days when I could sit for hours in my room, playing Halo.” Mike said with a wistful tone. He sighed and jerked a thumb to the door. “Go on then.”
The boy was away on his heels without a pause, eager to lose himself in his virtual world. Before long, however, he became aware of the subtle silence that had settled over the house; the routine coming and going of his parents had become so familiar that he no longer acknowledged it, but its absence created a profound, almost eerie change. He put his controller down and listened; what was Uncle Mike doing? Something outside, most likely – Uncle Mike was always outdoors when they visited him.
A pleasant tingling began in the boy's loins. Alone, with privacy. What a rarity that was...
His paw wandered to his waistband. He slipped his fingers inside, tips caressing his soft boyhood while his eyes fixed on his bedroom door and ears prickled for sounds of movement. Uncle Mike either didn't hear, or didn't care. He sighed, letting his mind drift to the task at paw; slow, careful strokes over the smooth, sensitive head of his penis sent pleasing shivers through his crotch. His teenage cock hardened swiftly at the attention, and Jeremy eased his pants down to let his cock and balls stand free. Clutching his now rigid length in paw, he began to stroke, his eyes closing as he conjured pleasing sexual fantasies to heighten the masturbation. Lost in the moment of his own gratification, he didn't hear the footsteps in the hall. The door opened, and it was far too late to hide his shame.
“Shit!” Jeremy yelped, covering himself with his paws while his uncle smirked in the doorway.
“Pretty sure that's not how games are played,” Mike said as he invited himself into the room. “I'm also sure your parents have strict rules about you not giving in to sinful urges.”
The young tom whimpered. “Please don't tell them!”
Mike's grin widened as he unfastened his belt. “I won't tell them, providing you take your punishment like a man. No-” the older male called out as Jeremy, with some reluctance, moved to roll onto his stomach. “You stay on your back. Drop those pants to the floor and keep your legs wide.”
“W-what are you going to do?” the teen whimpered, a cold shiver of dread running down his spine as he saw the hungry look in his uncle's eyes.
“I'm going to drive those vile thoughts out of you!”
The belt sang as it swung, the coil of black leather arcing down to slap across the top of Jeremy's furred sac. He shrieked as a fiery agony scoured through his tender flesh, legs clenching shut and paws flying down to protect his sensitive balls. Rapid huffs and pained whimpers filled the room as the boy struggled through the searing ache of the slap, but Uncle Mike was far from done. “Move your paws!” he barked.
Trembling, Jeremy obeyed. The belt swung again, slapping more to the side this time and knocking his nuts into one another. He let out a pained yowl, curling up protectively as hot, pulsing pain coursed through him. His feet trembled with the aftershocks of the smack. “If you can't keep position I'll tie you to the bed!” Mike barked, his voice full of a fury Jeremy had never known before.
“Please stop!” the teen wailed, tears welling up as he once more exposed his crotch to his uncle's fury.
“It stops when I'm satisfied you've learned your lesson!” With that, the belt flew once more, this time swung upwards in a swift, uncoiling strike that clipped Jeremy's sac from below. His nails drew ragged lines over his bedsheets as he fought against the bolt of pain, hot tears of agony and shame soaking his cheeks. The fourth smack came instantly, a downward return swing. The double-strike made spots flash in front of Jeremy's vision, his stomach knotting at the overwhelming, gut-wrenching pain. No matter how much he wailed for mercy, there was none to be found; by the time his uncle was satisfied the lesson had been learned, Jeremy's balls were a swollen, searing red, and he was bawling like an infant.
“Alright, that'll do,” Mike purred as he examined his handiwork. He tapped Jeremy's shin with his shoe to get the boy's attention. “I'll not tell your parents about this, so long as you agree to keep those dirty thoughts out of your head, and your paws off your parts. Deal?” Jeremy nodded urgently in response. Satisfied, Mike left the boy to clutch his aching balls and whimper out his pain.
Once the pain began to subside to a dull, but persistent ache in his crotch, Jeremy returned to his gaming. Less enjoyable now, he clung to that brief respite for as long as he was able to, though it soon became clear his uncle had other plans. This time, he was kind enough to knock on the door. “Come on out back, champ. I've got just the thing to keep your mind and hands occupied.”
Though the boy didn't like the sound of that one bit, Jeremy complied. He headed out into the garden to find the mower out and waiting, even though the grass was hardly tall enough to need it. “Cut the grass, and then grab a shovel when you're done. You know that old tree stump? You're going to move it!”
“Why? It's been there for years!”
Mike scowled at the boy. “Don't talk back! You're going to have to dig it out and uproot it. Do a good job, and there'll be a reward for you.” he finished with a slight smile.
Cursing under his breath, the young lad got to work. Cutting the grass wasn't so bad, but the mower was old and its wheels needed some attention; he'd worked up a bit of a sweat by the time he'd clipped the whole garden, and abandoned his top before setting to the second task. Digging out the stump proved a colossal struggle; the roots were thick and clung tight, forcing him to hack at them with the shovel, slamming the sharp edge of the blade into the thick wood over and over until his arms and back ached with the strain. Sweat pooled under his pits, dripped off his forehead, and trickled down his spine as each root was hacked apart, yet each time he tested the stump to see if he could lever it up, it still refused to budge.
By the time Mike returned, Jeremy was almost ready to collapse. He looked up upon hearing his uncle's shrill whistle. “Well, good to see you put the work in!” the older cat chuckled, his eyes wandering up and down the boy's bare chest. “Come on, you can call it quits now. Jump in the shower and then you can have some lunch. I ordered pizza!”
If there was a word that could make a boy's ears prick up, it was pizza. A smile formed on his face as he trotted back into the house with Mike close behind, though that smile faded as he realised he was being stalked all the way to the bathroom. “Just making sure you're not sinning,” Mike said in response to Jeremy's unspoken question.
With considerable reluctance, the boy stripped down and climbed into the shower. He tried to keep his back to Mike while in the stall, but that would have meant he had no way to wet down his front, and his chest fur was matted with sweat and dirt. “It's nothing I've not seen before!” Mike called over the hiss of water. “I've been putting you in the bath since you were six months old!”
Cursing, Jeremy turned and let the water splash over his front. He only briefly glanced Mike's way, and cursed the grin on his uncle's face. Uncle Mike, who'd always seemed so nice before, was enjoying his humiliation far too much! He did his best to keep his crotch out of sight through the ordeal, his face burning with embarrassment all the while. It was only made worse when his uncle loomed over him, damp cloth in paw, and pressed it firmly between his shoulder blades.
“Hey!”
“Oh grow up!” Mike shot back at the teen's protest. “You've got a river of sweat down your spine!”
The boy bit his tongue, accepting the rough handling by his uncle with a hot blush on his face. Mike sniffed deeply as he worked. “I do wonder if you even know how to clean yourself properly. Most teen's don't. You can't just splash warm water over your pits and bits and call it done.”
The flannel reached the base of his spine and shot down further, curling under his tail. Jeremy jumped at the touch, feeling rough fingers curl against his cheeks. Mike laughed at the youth, paying no heed to his protests. “Fond of that sweaty stain, were you? No wonder your room smells like old socks and rotten eggs!”
Jeremy bit back a curse and lowered himself back into the water. “I can wash the rest,” he mumbled, trying not to put on more of a show than he had already, but still he felt Mike's paw press firmly against his chest, fingers groping through the flannel to squeeze at his young, still forming muscles. A timid whimper slipped free of Mike's lips as the paw worked downward towards his groin...

Thankfully, the doorbell saved Jeremy any further torment. With Mike called away by its song he was able to hastily finish washing, drying and dressing himself in private. As he headed downstairs, the welcome smell of pizza wafted towards him. Mike was already sat at the dining table with the pizza box open and two slices taken. “Take all you want!” he called to the boy. “I shouldn't even be having this much. Enjoy the greasy junk food while you can; the salads arrive before you know it!” he added with a sigh, glancing at the greenery on his plate.
By the time he'd ate his fill, which was half the pizza, the twelve year old was smiling again with all previous hurts forgotten. Uncle Mike was smiling too, albeit for reasons Jeremy had yet to discover. While the youth had been hard at work in the garden, the older tom had gone shopping for 'performance enhancing' drugs, buying large amounts from several stores. The bulk of the pizza pie was laced with the stuff, and he knew there wouldn't be much of a wait for the effects to kick in.
They settled on the sofa to watch some TV, but Jeremy was squirming within minutes. He kept shifting himself and adjusting his shorts, which sported a prominent bulge.
Though he'd noticed straight away, Mike kept his glances sidelong for a good while, enjoying the boy's discomfort and growing distress. When he suspected Jeremy might try to slink away, he 'happened' to notice.
“Hold it!” Jeremy flinched at his uncle's shout. The boy kept his back to Mike as the older male stepped over. He let out a yelp of shock as Mike's paw came round his hips and gripped his bulging member. “I knew it, you're still full of filthy thoughts!”
“G-get off!” Jeremy pulled away, trembling and confused by both what was happening in his groin and the groping of his uncle.
“We need to get those dirty thoughts out of you.” The words drew a shiver down the boy's spine as he recalled the earlier belting. “You sit right there until I get back.”
Stewing in his fear, Jeremy was left with nothing to do but fret what punishment might be coming, and focus on his rigid cock. He'd never been this hard in his life, and the blood flowing to his groin was making him light headed.
Mike's return was sudden and fierce. Before Jeremy knew what was happening, his uncle had him by the wrist and was twisting his arm back behind his back. Mike squealed and tried to pull away, only to trip and land awkwardly on the sofa. Uncle Mike pinned him down and wrestled the boy's other arm behind his back and binding his wrists with a zip tie.
“We're going to need drastic measures to cure you of these sinful thoughts!” Mike announced as he pulled the boy up off the seat and yanked down his shorts. The boy squealed in shock and almost fell again, but Mike caught him. With one arm locked around the boy's chest, the other reached down past the youth's over-hardened cock and closed around his young sac. Jeremy let out a squeal of pain as the older cat began to squeeze the defenceless boy's nuts in a hard, vice-like grip. Long yowls of agony bounced off the walls as Jeremy's testicles were ground together like medicine balls, the older male's claws digging into the tender skin adding a sharper, urgent pain to the crushing sensations that left Jeremy struggling to stand.
“Don't tell me you're enjoying this!” Mike barked, playing dumb to further torment the boy. He knew all too well why Jeremy's cock wasn't softening under this torment.
He released the boy's balls, but only to give Jeremy a moment to catch his breath. Then he curled his paw into a fist and punched down as hard as he could, smacking the lad's abused and vulnerable sac with all his might. Jeremy doubled over, and Mike let him, taking the chance to circle round for a better position. “This is going to hurt me more than it hurts you,” he said with a mocking tone of concern. As Jeremy raised his teary eyes, Mike struck again. The blow landed squarely, causing Jeremy to crumble to the floor, dry heaving at the intense waves of pain the low strike had caused.
“There we are, that hit the spot.” Jeremy blinked away the tears from his eyes, seeing his erection easing down to half-hardness. A shameful dribble of precum leaked from his tip, bubbling up into a fat droplet before trickling down his length. “You should call it a night. A bit of rest will do you good.”
Too tired, hurt, and scared to argue, Jeremy simply nodded and followed, head bowed, as his uncle lead him upstairs. The young cat winced at every step as each movement of his hips caused his tortured balls to rub against each other or bounce against his thigh, sending out new pulses of pain. He hadn't the will to protest when Mike watched him undress, but was glad that his uncle chose only to observe – at least until he climbed into bed. “Paws up to the headboard!” Mike barked, making the lad jump in shock. “You've been far too feisty today, so I'm taking steps to make sure you don't play with yourself!” Jeremy meekly complied and found his paws bound above his head, leaving him defenceless against whatever predations his Uncle might have planned. The fear of further cruelty subsided, briefly, when Mike left the room, only to be replaced with a new concern; left now to try and rest, the boy's focus returned to his still swollen member. Despite the abuse his fragile balls had suffered through, his cock had hardened again. Each little twitch stroked against the thin, silken sheets, sending a pulse of pleasure through his body. Each time he shifted to try and get comfortable he would tease himself further, and so he tried to squirm onto his side to avoid this.  With his arms bound spread, that left his spine in an unpleasant twist that soon began to ache, forcing him to lie on his back again and, in the process, resume the torment. In time he surrendered to his building lust and began humping the sheets on purpose, eager for what little friction they could grant, but it served only to tease and edge him all the more. The darkness of the room filled with his soft whimpers of frustration, and the musky scent of his sweat.
At some point, the mercy of sleep took hold. Jeremy woke to aching arms and heavy balls, and though his morning wood faded the weight of his sac did not. Even when soft, his need to cum was bordering on painful. His Uncle unbound him and let the boy stretch, rub some feeling back into his wrists, and tend to his bathroom needs before breakfast. As Jeremy finished his morning meal he felt his cock swell once more, and he let out a frightened whimper at this unwanted arousal. Why now? Why was it happening so much? The answer lay in the drugs his uncle had once more laced his food with, bringing him to painful hardness once more.
In the privacy of the bathroom, the boy examined himself. His cock was an angry red, bulging to the point of painful. Beneath the fur of his sac, his well-punished balls had hints of yellows and the purplish spots of bruises from the beatings they'd received the day before. He had no wish to suffer through all that again, but he had no idea how to stop this maddening arousal!
His paws closed around his rigid length. He'd be in real trouble when Mike found out how horny he was, so was it better to just get rid of it? He was scared of how much worse the punishment would be if he masturbated, but he couldn't stand to hold back either.
As if sensing the boy's turmoil, a harsh banging on the bathroom door came to shatter his peace. “You had best not be playing with yourself in there!”
It was then that Jeremy's will shattered. Thick, shameful tears streaked down his face, a mixture of pain, fear, and shame at his body's betrayal. The door banged again. “Open the door, Jeremy. Open it up right now!” His paws shook as he reached for the lock and fumbled it, only managing to twist the little knob on the third attempt. He stepped back as the door swung in to reveal his stern Uncle. the motion made him trip on his own tail and stagger against the sink, banging an elbow hard against the porcelain. He saw nothing warm and loving in Uncle Mike now, even if the older feline shifted his face into a mask of sympathy.
“Still full of urges, huh?” He gave a theatrical shrug. “I guess we're past the point of just punishing the sin out of you.”
“Don't!” the teen squeaked, his voice weakened and pathetic.
“Relax, kid. I'm going to give you what you want.” Mike flicked a paw towards Jeremy's crotch in a lazy gesture. “We both know the only way that's going down is for you to jerk off. Get to it, lad! Before I change my mind. Or do you not know how?”
Mike stepped up and grabbed at the waistband of Jeremy's pants. A brief, futile struggle followed, ending with the older feline's paw shoved down the boy's briefs, clutching his twitching, leaking cock. Jeremy was left frozen in place, both by the shock of the touch and the deep, primal lust the contact left in him. “There you are, see?” Mike purred as his paw began to make long, lazy strokes of the teen's cock. He pulled his paw free and grinned. “Go on, you can do the rest.”
Raw horniness overcame the mountain of shame Jeremy felt at the idea. Lowering his gaze and trying to blot out the thought any thought of his uncle's presence, the boy's paws closed on his painfully hard cock, the mere act of holding it sending pleasing pulses through his body. His head swam as he began to stroke himself, curling his fingers around his sensitive helmet and letting his thumb smear the bubbling pre from the tip down and over his glans. More fluid bubbled up to replace what had been wiped away by the downstroke, smoothing and soothing his personal exploration. A whimper of pleasure slipped out, turned suddenly to a sharp rasp as the side of his paw pressed against the top of his sac and inflamed yesterday's bruises. He used his left paw to cradle his tortured balls, supporting and shielding them so they would not bounce or grind as he sought to pleasure himself. A few more strokes let him find a rhythm that maximised his own pleasure with minimal aches and twinges from his testes, each upstroke gathering more leaking pre to smear along his reddened, swollen manhood, his paw jerking down but coming to a halt just before he would smack his own sac again. As the pressure of his impending orgasm built, even the aches and pains he'd earned the day before became a perverse kind of stimulation, each sore ache and tender sting another crack in the dam that was about to break. Lost to his own lust, he forgot his watching Uncle; he barely remembered that his climax was going to make a mess until it was almost too late. Throwing his paw over the tip of his cock, Jeremy gasped and grunted through a powerful, painful climax, coating his paw in shameful seed. A stray spurt found a gap in his fingers and flicked across his knuckles, while another rogue spurt trickled towards his wrist before spattering onto the bathroom floor. As post-nut clarity came to the boy, he swung the shameful, wobbling clump of spunk over to the sink and washed it away, using hefty dollops of hand soap to stop it sticking to his paw or the plughole.
“Feel better?” Mike asked, and Jeremy nodded urgently at the question without turning around. If he had, he might have had some warning as to what his uncle had planned; a sudden spike of agony shot through him as a fierce kick from behind slammed into his dangling sac.
Jeremy's breath shot from his lungs in a choking gasp. His legs buckled and he fell, trying to catch the sink as he dropped, unprepared for such a cruel ambush. As he hit the tiled floor and sprawled out he caught a fleeting glimpse of his uncle, the older man's cock out on full display. Before the teen could react, Mike raised his booted foot and stomped down hard on Jeremy's crotch, crushing his tender balls and slowly shrinking cock in a fierce, ruthless strike. In desperate panic, the howling boy tried to claw at Mike's leg, but that only made him grind his heel down all the harder.
“I wish I had a kid of my own. I love how you kittens squeal!” Mike snarled as he popped his slacks open, freeing his rigid cock from its cage. He shamelessly began to stroke himself as the boy beneath him squirmed and howled. He raised his boot, giving Jeremy just a moment to breathe before throwing a full-force kick into the helpless teen's groin, doubling the pace of his own masturbation as Jeremy's shrieks shook the room.
A final, devastating blow smacked into the boy's tortured balls, a hooking kick that lifted his hips off the ground with its force. He almost blacked out from the pain, curling up as Mike finally released his ankle, and dry heaving in a foetal ball. He heard a harsh, lurid grunt from above, and felt the patter of warm droplets on his side. His nose wrinkled at the unmistakable scent of spunk now gluing clumps of his fur together. With a final, satisfied huff, Mike stepped over the prone boy, eased the door open as much as the teen's sprawled body would allow, and left him.
He lay where he'd been left, trembling, sobbing. Gingerly, his paw cupped his tortured balls, but even this tender touch drew shuddering yelps from his lips. He inspected himself as best he could, terrified he'd suffered some permanent damage. All he found was swelling and bruising, for what little mercy that was.
As he struggled to his feet, legs barely able to support him, head reeling from the waves of pain surging from his crotch, a sickening realisation slammed its way into his mind with such force he had to grab the sink for balance. His parents still wouldn't be back for another twelve days.
He fought back a childish sob, gritting his teeth against whatever Hell might follow, and slunk his way out of the bathroom.
