Brandon is back from college, and he’s been experimenting with pumping and jelqing. Now he’s home again to visit his single dad, and gets the idea to see if he’s bigger than his old man.

Chapter 7: Brandon’s bitch

holy shit, son, you’re stretching me wide open," Michael groaned, his voice a low, guttural rumble. The intensity of the sensation was almost too much to bear, but the raw, primal connection between them was undeniable. Every nerve ending in his body came alive, every muscle tensing and relaxing in waves of pleasure and pain. Brandon, feeling his father’s body shudder beneath him, pulled back slightly before thrusting forward again, his hips slapping against Michael’s ass. "That’s it, Dad. Take every inch of me.

Show me how much of a man you are." The words were a primal challenge, a demand that set Brandon's blood on fire. He gripped his father's hips tighter, his fingers digging into the flesh, and pulled back, the head of his cock stretching the tight entrance before slamming back in. Michael's groan was low and guttural, his body shuddering with the force of Brandon's thrust.

Brandon began to move, his hips finding a punishing rhythm that had Michael gasping for breath.

Each thrust was a powerful invasion, the thick shaft driving deep into Michael’s body, stretching him like he’d never been stretched before. The sounds of their bodies slapping together filled the small bathroom, wet and obscene.

“ Fuck, ” Brandon grunted, his voice ragged with lust and exertion. “ You’re so tight, Dad. You feel so fucking good. ” His hands on Michael’s hips were brutal, his fingers digging mercilessly into the flesh, holding his father in place as he pounded into him.

Michael’s body was on fire, every nerve ending alive with sensation.

The raw, primal pleasure of being claimed by his son, of being filled and stretched like never before, was overwhelming and intoxicating. He could feel every inch of Brandon inside him, the thick cock pulsing, the heavy balls slapping against his body with each forceful thrust. He gripped the countertop tighter, his knuckles white, his muscles tensing and relaxing with each punishing invasion.

“Fuck, son!” he groaned, his voice a low, guttural rumble.

"I'm not close yet, Dad. Not even close. I want to see how much I can take, how much you can take." Brandon’s eyes were wild with determination, his body taut with the effort to control himself, to hold back from the brink. He wanted to edge himself, to test his limits, to see how long he could last before he finally let go. And he wanted to use his father's body to do it. He wanted to see how much he could make Michael take, how much he could stretch him, how much cum he could fill him with before he finally exploded.

Michael’s eyes widened at the challenge, a mix of fear and excitement swirling in their depths. He knew what Brandon was capable of, had seen his son’s size, had felt it deep inside him.

But the challenge in Brandon’s voice, the raw, brutal determination, sent a shiver of fear and excitement coursing through him. "You want to see how much I can take, son?" Michael growled, his voice a low, dangerous rumble. He could feel the heat in Brandon, the raw, primal power that radiated from him, and it thrilled him, terrified him, consumed him. He wanted it, needed it, craved it like he had never craved anything before. But he also knew that he couldn’t back down, that he had to meet Brandon’s challenge, had to prove to his son that he could handle it, could take everything that he had to give.

"Yes, Dad," Brandon whispered, his lips brushing against Michael’s ear, sending a shiver down his spine.

"I want to see how much you can take. I want to fill you completely." His pace quickened, his hips moving faster, his cock driving deeper with each thrust. Michael’s eyes widened at the sudden increase in intensity, his body tense with the effort to keep up. He could feel every inch of Brandon, the thick shaft stretching him, the heavy balls slapping against him with each punishing invasion. His grip on the countertop tightened, his knuckles turning white as he fought to hold on, to take everything that his son was giving him.

"Fuck, son," he groaned, his voice barely above a whisper. "You're going to rip me apart." The words were a mix of fear and awe, a raw, primal recognition of the power that Brandon held over him.

Brandon’s eyes rolled back in his head, a primal, feral look consuming his features. He grabbed his poppers from the counter, the small bottle shaking in his hand. With a wild grin, he took a massive hit, the vapors filling his lungs, his brain buzzing with the chemical rush. His tongue lolled out, drool dripping from the corner of his mouth as he lost himself in the high. He was going deep, going goon, his mind losing focus, his body driven by pure, primal instinct. He gripped Michael’s hips tighter, his fingers digging into the flesh as he began to move, his hips finding a steady, punishing rhythm. He was using his father now, using him as a fucksleeve, a vessel for his pleasure, a tool to satisfy his raw, primal needs.

The poppers had taken him deep, had stripped away his inhibitions, had reduced him to a primal beast, driven by instinct and hunger. Brandon’s cock swelled even more, the thick shaft stretching Michael’s ass wider, the heat and the pleasure overwhelming in their intensity. Michael groaned, his body shuddering as he felt his son’s cock growing, felt himself being stretched even wider, felt his body being claimed even more thoroughly. He could feel the raw, primal power radiating from Brandon, could feel the heat and the hunger that consumed him, and it was terrifying and thrilling and intoxicating all at once.

He wanted to come, wanted to let go, wanted to surrender to the pleasure that consumed him, but he couldn’t, not yet.

He had to push himself, had to go further, had to see how much he could take, how much he could make his father take. He looked down at the thick, veiny shaft that dripped a constant stream of pre-cum, the sight sending a fresh wave of lust coursing through him. He couldn’t believe how big he was, how much he had grown, and he wanted to use every inch of it, wanted to see what his body was capable of, wanted to see how much his father could take.

He gripped Michael’s hips tighter, his fingers digging into the flesh, his body driven by pure, primal instinct. He felt a surge of power, of dominance, as he used his two-foot cock to rearrange his father’s guts, to stretch him wider than anyone had ever gone before.

The room was foggy with sweat and sex, the stink of pure lust, ass, and cock soaking every surface. The sound of his heavy, massive balls slapping against Michael’s flesh permeated the room, a primal rhythm that echoed his thrusts and his need.

“You’re mine now, Dad,” Brandon grunted, his voice thick with lust and power. “All mine. Your body, your hole, they’re all for me.”

Michael groaned, his body trembling with the effort to take it all, to meet his son’s challenge. “Fuck, Brandon,” he breathed out, his voice a ragged gasp. “You’re so big. Too big.”

Brandon’s eyes gleamed with a feral light, his lips curling into a wicked grin.

"You're doing so well, Dad. So fucking well," he praised, his voice a low, guttural rumble. Michael's body tightened around Brandon's cock, his muscles clenching as he came, his cock glazing both men with cum, the hot liquid spilling out, coating their stomachs, their thighs, their balls. Brandon moaned in pleasure, the sensation of his father's hole gripping his massive pole driving him wild. He could feel every pulse, every squeeze, every shudder of Michael's body as he came, and it was almost too much to bear. But he didn't stop, didn't even slow down. He kept fucking, kept pounding into his father, unphased by his orgasm, his grin only growing wider, his eyes gleaming with a mix of lust and pride.

Michael looked back at him, his body still trembling with the aftershocks of his orgasm, his eyes wide with disbelief.

“Brandon… you’re… you’re still hard?” he panted, his voice filled with both awe and exhaustion.

Brandon’s eyes rolled back, his tongue lolling out of his mouth as he lost himself in the primal, beastly high of the poppers. He was driven by pure, raw instinct now, his body moving on autopilot, his cock throbbing with a life of its own. “Fuck… yes…” he grunted, his voice a low, guttural growl. He was going to ride this high until it was gone, until he had wrung every last drop out of it. He needed to, needed to see how far he could go, how much he could take.

He pulled out of his father, his cock glistening with sweat and cum, the sight alone sending a fresh wave of lust through him. Michael, his body still trembling from the force of their fucking, turned to look at him, his eyes filled with a mix of awe and exhaustion. Brandon checked his reflection in the foggy mirror, his eyes wide with primal hunger. The sight of his massive, throbbing cock, the veins pulsing with need, the head glistening with pre-cum, sent a fresh surge of power coursing through him. He looked like a beast, a primal, feral creature driven by pure, raw instinct, and he loved it. He loved the sight of his body, of his cock, of the desire that radiated from him like a palpable force.

And then, just like that, it twitched. A sudden, involuntary movement that had him gasping, his body tensing, his cock pulsing with need. It was a visceral, primal response to the sight of his father's quivering hole, to the memory of the raw, intense pleasure he had given and received. "Fuck," he groaned, his hips jerking forward, his cock twitching again as if trying to find its way back into Michael's body. His father turned to look at him, their eyes meeting in the mirror, a silent understanding passing between them. Despite the exhaustion and the ache in his body, Michael's cock was starting to stir, the sight of his son's primal hunger rekindling his own desire.

Brandon's cock twitched again, a clear sign that he was nowhere near finished, that he still craved more, demanded more. Michael's eyes widened as he felt his own body respond, his cock swelling, the need for his son's touch, for his dominance, consuming him. The room was thick with their combined scent, a heady mix of sweat, cum, and raw, primal need that was almost overwhelming.

“Fuck, Dad,” Brandon groaned, his voice a low, guttural rumble, his eyes locked onto Michael’s reflection in the mirror. “Your hole, it’s still so fucking tight. So perfect. I need to feel it again. I need to make you mine again.”

Michael’s breath hitched, his body tensing as he felt a fresh wave of desire course through him.

“Fuck, Brandon,” he breathed out, his voice barely above a whisper, surprise and arousal coloring his words. “You can’t be serious. You can’t possibly want more already.”

Brandon’s eyes gleamed with a mix of lust and possessiveness as he stepped closer, his massive, glistening cock swinging heavily between his legs. “I thought you knew me better than that, Dad,” he growled, his voice a low, dangerous rumble that sent a fresh shiver of excitement down Michael’s spine. “I always want more. Especially when it comes to you.”

Michael’s eyes widened with surprise, his body aching with the memory of the raw, intense pleasure his son had just given and taken from him. He couldn’t believe that Brandon was already hard again, already hungry for more.

His son’s massive cock, glistening with sweat and cum, was already standing at attention, the tip already leaking pre-cum. Michael’s eyes widened in disbelief. “You’ve got to be kidding me,” he panted, his voice shaking with a mix of exhaustion and awe. “How are you still so hard? How are you still so… insatiable?”

Brandon’s lips curled into a wicked grin as he stepped closer, his massive body blocking out the light, his cock swaying slightly with each step. “I’ve been working out, Dad,” he said, his voice low and teasing. “I’ve been training. I’ve been... conditioning. And now I’m ready to use every ounce of that training on you.

Brandon’s shaft throbbed in front of both men, lurching out another two inches in length, both of them gasping, Michael in fear, Brandon in lust. The shock of seeing his son’s cock grow even larger, the sheer impossibility of it, made Michael take a stumbling step back, his eyes wide with disbelief.

“Brandon,” he stammered, his voice filled with a mix of awe and trepidation. “How... how is this possible?”

Brandon’s eyes were wild, his hunger for his father undeniable. “I told you, Dad,” he growled, his voice thick with lust. Pushing my limits.

Showing you what I can do. What I can make you take," and with that, his cock twitched again, the sight sending a fresh shiver of both fear and arousal down Michael’s spine. He couldn’t believe what he was seeing, what he was feeling. It was as if his son's body was no longer his own, driven by some primal, insatiable force that defied all reason and logic.

"Brandon, wait," Michael pleaded, his voice barely a whisper, his body tensing with a mix of desire and apprehension. "You're too much, son. You're going to hurt me."

Brandon's eyes blazed with a wild, untamed hunger, his body trembling with the effort to contain his lust. "No, Dad," he growled, his voice a low, primal rumble. "I won't hurt you.

Not unless you want me to," Brandon growled, his voice a low, primal rumble. His cock twitched again, growing by millimeters with every heartbeat, lengthening and thickening before their very eyes. Michael gasped, his eyes widening in shock and disbelief as he watched his son's cock continue to grow, to swell, to become something almost monstrous.

"Brandon, no, please," he begged, his voice shaking with a mix of fear and arousal. "It's too much. You're... you're too big."

Brandon's lips curled into a cruel smile, his eyes gleaming with a wild, untamed hunger. "You think so, Dad?" he taunted, his voice thick with lust. "You think you can't take it?

You think it's too much?" Brandon taunted, his voice thick and raw with desire. His cock pulsed, growing even larger, the sight making Michael's eyes widen with a mix of fear and arousal. Brandon's cock now stood massive and proud, veins throbbing, the thick shaft seeming to defy the laws of physics as it continued to grow. "You think I can't make you take every fucking inch?"

Michael's breathing quickened, his body tense as he watched his son's cock stretch and grow, the sight both terrifying and arousing. "Brandon, please," he begged, his voice shaking with a mix of fear and need. You'll hurt me."

Brandon's eyes flashed with a wild, primal hunger. "I hurt you, Dad?

Fuck, no," Brandon snarled, his voice a deep, primal growl that resonated in his chest. He lined his massive cock back up to his father's now impossibly tight hole, the new size definitely going to stretch out his dad's ass even more. He thrust forward, his cock bulging out his father's abdomen obscenely, able to trace the outline of his enormous cockhead through the thin skin. Michael grunted, his hands slapping against the wall as he tried to brace himself, his body tensing as he felt the massive intrusion.

"Fuck, son, you're... you're too much," he panted, his voice shaking with a mix of pain and pleasure, his body struggling to accommodate the sheer size of his son's cock. Brandon's eyes were wild, his body driven by pure, unadulterated lust.

As he watched his father's hole stretch and yield to his immense cock, his shaft twitched, growing even larger, as if his body was responding to the challenge, the need to claim Michael completely. He felt a surge of power, of dominance, as his cock stretched his father's ass wider, the veins throbbing with every pulse. The sight of his massive cock, glistening with sweat and pre-cum, sent a fresh wave of desire coursing through him, his hips moving faster, his body driven by pure, primal instinct.

Michael grunted, his body trembling with the effort to take it all, to meet his son's challenge. He could feel every inch of Brandon, the thick shaft stretching him, the heavy balls slapping against him with each punishing thrust.

But suddenly, impossibly, Brandon’s cock grew even larger, the girth and length swelling to unimaginable proportions. Michael’s eyes widened in shock and disbelief, a gasp escaping his lips as he felt the sheer size of his son’s cock threaten to split him apart.

“Brandon, no!” Michael cried out, his voice a mix of fear and pain. “You’re… you’re too big! You’re going to tear me apart!”

Brandon’s eyes were wild with lust and madness, his body driven by a primal force that he could no longer control. He felt his cock throb and pulse, the veins standing out like ropes as it continued to grow, to swell, to become something monstrous and inhuman.

The sight of his father's wide, terrified eyes, the feel of his body struggling to take him, sent a fresh surge of power and desire coursing through him. Brandon's lips curled into a cruel, primal snarl, his body driven by an insatiable, uncontrollable hunger. "You think you can't take it, Dad?" he growled, his voice a deep, guttural rumble. "You think it's too much?" His cock twitched again, the length and girth growing even more, defying all logic and reason.

Michael's eyes widened even further, his breath coming in short, ragged gasps as he felt his body being stretched to the absolute limit. He could feel every inch of his son's cock, the veins pulsing against his inner walls, the thick shaft throbbing with each heartbeat.

The sensation was overwhelming, borderline excruciating, but there was something primal, something raw and animalistic about it that sent shivers down his spine, that had him pushing back against the invading length, meeting Brandon’s thrusts with desperate, desperate need.

Brandon's eyes flashed with wild hunger, his body driven by a primal, insatiable lust that was beyond his control. The sight of his father's body, stretched and filled with his massive cock, was intoxicating, the knowledge that he was pushing him to the edge of his limits sending a fresh surge of power and desire coursing through him.

"You want it, Dad, don't you?" Brandon growled, his voice a low, guttural rumble, barely recognizable as his own. "You want to see how much you can take.

His cock throbbed, growing even larger, a surge of pure, animalistic power coursing through him. "You want to feel every fucking inch of me, don't you?" Michael's eyes widened in shock and disbelief as he watched his son's cock continue to swell, defying all logic and reason, the sight making him gasp out loud. "Brandon, please," Michael begged, his voice shaking with fear and arousal, his body tense as he braced himself against the wall, his hands slapping against the cool tile. "You're too much. Brandon's eyes flashed with wild, untamed lust, his body trembling with the effort to contain his hunger. "Hurt you, Dad?" he growled, his voice a deep, primal rumble.

"Then take it, Dad. Take every fucking inch. Show me what you're made of."

Michael’s body trembled, his muscles straining and quivering as he struggled to accommodate the sheer size of his son’s cock. Sweat beaded on his forehead, his arms shaking as he tried to push back against the unyielding force of Brandon’s thrusts. His breath came in short, ragged gasps, his body aching and burning with the effort to take it all, to meet his son’s challenge.

The sound of their flesh slapping together filled the room, a primal rhythm that echoed the intensity of their fucking. Brandon’s balls slapped heavily against Michael’s ass, the sound obscene and raw, a testament to the ferocity of their coupling.

His cock throbbed again, a sudden, violent pulse that sent a fresh surge of pre-cum spilling out, coating his father’s insides with its slick, hot fluid. Michael groaned, his body shuddering as he felt the renewed girth, the intense heat that radiated from Brandon’s massive organ. “Fuck, Brandon,” he breathed out, his voice a low, ragged gasp. “Your cock… it’s… it’s growing again.” His fingers dug into the tile, his knuckles white as he tried to brace himself, to hold on as his son’s cock swelled even more, stretching him wider, filling him more completely than he ever thought possible.

Brandon’s eyes were wild, his body driven by an insatiable, primal hunger. “Take it, Dad,” he growled, his voice thick with lust and power.

“Take every fucking inch.” Brandon’s thrusts became more intense, his massive three-foot cock shoving its way through his father’s intestines, each powerful stroke pushing deeper, wider, demanding more. Michael’s body shook violently with each thrust, his hands slapping desperately against the wall as he struggled to maintain his balance.

The sudden increase in size and force was almost too much for him to bear. His body felt like it was being torn apart, the intense pain and pleasure mixing together in a confusing, overwhelming sensation. “Fuck, Brandon!” he gasped, his voice a ragged cry. “You’re too big! You’re hurting me!”

Brandon’s eyes were wild, his face a mask of primal, uncontrollable hunger. “You can take it, Dad,” he snarled, his voice a deep, guttural rumble.

“You can take everything I give you.” Michael’s body trembled, his muscles straining, his breath coming in short, ragged gasps. Brandon’s cock throbbed and surged, the heat and the power radiating from him like an unstoppable force. Michael could feel the walls of his ass stretching to their limit, his body aching and burning with the effort to accommodate his son’s monstrous cock.

Suddenly, Brandon’s body stiffened, his eyes widening with shock and disbelief. “Dad, your body…” he trailed off, his voice shaking with a mix of fear and awe. Michael’s body seemed to shudder and pulse around Brandon’s cock, the walls clamping down on him, the muscles rippling and contracting in ways that were both pleasurable and terrifying.

Brandon felt a rush of power, a surge of dominance as he continued to saw his massive organ in and out of his father, the sound of flesh slapping against flesh filling the room like a primal drumbeat. Despite the heat and the slickness, despite the sheer size of his cock, it seemed as if Michael’s body was changing, adapting to accommodate him, to take everything he had to give.

The sensation was unlike anything he had ever experienced, a raw, primal power that coursed through him like an unstoppable force. He could feel every inch of his father’s body, every ripple and pulse, every desperate, desperate need. It was intoxicating, a drug that drove him on, that made him push harder, fuck faster, demand more. He wanted every inch of his father, wanted to fill him completely, to claim him utterly.

The sun was beginning to rise, casting a soft, golden light over the two of them, their bodies slick with sweat and cum. Michael was exhausted, his body aching and trembling with the effort of taking his son's immense cock, but there was awe and admiration in his eyes as he looked back at Brandon. Seven hours they had been going at it, and his son's stamina was astonishing, his cock as hard and enormous as it had been when they started.

"Fuck, Dad," Brandon grunted, his voice thick with lust and determination. "I'm going to take you on a wild ride. I want to see how much you can take, how much you can handle." He reached for the poppers, his fingers fumbling slightly with exhaustion, but his eyes were wild with lust and determination.

He couldn’t stop, wouldn’t stop, not until he had wrung every last drop out of this primal, insatiable hunger. He took a deep hit, the vapors filling his lungs, his brain buzzing with the chemical rush. But he needed more, wanted more, craved more. He reached for the lube, the cool slickness against his fingers a welcome contrast to the heat of his cock. He sprayed it liberally, coating his massive length, the sight of his glistening shaft sending a fresh surge of desire coursing through him. He grinned wickedly, his eyes locked onto Michael, a predatory gleam in his gaze. "Fuck, Dad," he growled, his voice thick with lust. "Your body's being so good to me. So fucking good. But I want to make it better. I want to make it perfect.

I want to see your body take me so deep, so completely, that you'll never be the same again." Brandon's cock throbbed again, a fierce, insistent pulse that sent a fresh wave of pre-cum spilling out, the sight making Michael's eyes widen with a mix of awe and trepidation. He could feel the renewed girth, the intense heat that radiated from his son's massive organ, and he knew that he was in for something even more intense and overwhelming than before. But there was no turning back now, no escape from the raw, primal power that consumed them both.

"Fuck, Brandon," Michael gasped, his voice a low, ragged whisper. "Your cock... it's... it's growing again. I don't know if I can take it, son.

Brandon's cock pulsed, growing even larger, the veins standing out like ropes as it strained to fit inside Michael's stretched and battered hole. Michael's eyes widened in shock and disbelief, a low moan escaping his lips as he felt the sheer size of his son's cock threaten to split him apart.

Brandon, too, looked down, his eyes widening at the sight of his massive, throbbing member. "Fuck, Dad," he breathed out, his voice filled with a mix of awe and disbelief. "It's... it's getting bigger. I don't know if I can control it." Michael's body trembled, his muscles contracting and clenching around Brandon's cock, the raw, primal sensation of being filled so completely sending shivers of both pleasure and pain down his spine.

Brandon's eyes glazed over, his pupils dilating as he surrendered his brain to his cock, his body just a vessel for his cock to fuck endlessly with. Over 40 inches of cock now ruining his dad's insides, Brandon's brain was dead, his only thought, his only existence, to fuck.

The world around him faded to a blur, his vision narrowing to the sight of his father's body, the sound of flesh slapping against flesh filling his ears like a primal drumbeat. He was lost to it, lost to the heat and the slickness, to the raw, unbridled power that coursed through him like an unstoppable force.

He felt a distant, detached awareness of the pain in his father's voice, the desperation in his plea, but it was only a faint, irrelevant echo.

The world had narrowed down to the raw, primal sensation of his cock, the insatiable need to fuck, to claim, to conquer. His massive, throbbing member was a living thing, a beast with a mind of its own, and it demanded satiation. It didn't matter if his father couldn't take it, if he was in pain. The only thing that mattered was the relentless, driving rhythm of his hips, the erotic symphony of flesh against flesh, the raw, primal power that radiated from him like a physical force.

The world faded away, the pain in his father's voice becoming a distant, insignificant thing, as Brandon's body moved on autopilot, his massive cock plunging in and out of Michael's battered, stretched hole with a brutal, relentless force.

Brandon's brain had surrendered to the needs of his cock, all higher thought and reason drowned out by the primal, insatiable hunger that consumed him. He was a beast, driven by pure, raw instinct, his body reduced to a vehicle for the relentless, mindless fucking of his father's body.

Brandon's vision narrowed, the details of the room blurring into a hazy, irrelevant background as his world shrank down to the sight of his massive, glistening cock, the sound of flesh slapping against flesh, the raw, primal power that coursed through him like an electric current. He felt no remorse, no pity, no concern for the pain and desperation in his father's voice.

Brandon was completely lost in the moment, his body and mind surrendered to the raw, primal power that consumed him. His massive cock throbbed and pulsed, the veins standing out like ropes as he continued to fuck his father with a brutal, relentless force. Suddenly, he felt a surge of pleasure so intense, so overwhelming, that it consumed him entirely. His vision blurred, his body tensing as a wave of heat and light exploded through him, his cock throbbing and jerking with a force that seemed to tear him apart. He let out a guttural roar, his body shaking and convulsing as he came with a force that left him breathless, his vision swimming with spots of light. For a moment, he was lost, adrift in a sea of pleasure and pain, his body consumed by the raw, primal power that coursed through him.

But then, suddenly, he felt it—a slight, almost imperceptible change in the rhythm of his father's body. Michael's body trembles, his muscles clenching and unclenching around Brandon's cock, the sensation sending a fresh shiver of both arousal and concern down his spine. He paused, his breathing ragged and harsh, his senses suddenly sharpened. "Dad?" he gasped, his voice barely above a whisper, his eyes searching his father's face for some sign, some clue.

Michael's eyes were squeezed shut, his face a mask of pain and desperation, his body trembling and shaking with the effort to accommodate his son's monstrous cock. He opened his mouth to speak, but all that came out was a ragged, choking gasp, his body convulsing as if he were being electrocuted.

His cock, now a monstrous, vein-ridden beast of over 45 inches, surged with a life of its own, the momentum taking over as Brandon lost the last remnants of self-control. He threw his head back and let out a primal, guttural roar, his hips moving at a speed that defied human capability. His cock, dripping with sweat and pre-cum, slammed into his father's gut with a force that was almost obscene, the sound of flesh meeting flesh echoing through the bathroom like thunder.

Michael's body convulsed with each punishing thrust, his internal organs feeling like they were being rearranged, his body struggling to keep up with the relentless, brutal fucking.

But just as it seemed like he might be able to endure this savage assault, Brandon's cock swelled even further, the already immense girth stretching his father's insides to the point of agonizing pain. Michael's eyes flew open, his breath catching in his throat as he felt the sheer size of his son's cock, the heat and the power that radiated from it like a physical force.

"No, Brandon, please," he gasped, his voice a ragged plea, his body trembling with pain and exhaustion. "You're... you're too big, son. I can't... I can't take anymore." Brandon's eyes were wild, his body driven by a primal, insatiable hunger that was beyond his control.

As he looked back at his father, he felt a sudden, overwhelming surge of possessiveness, of territorial dominance. His grip on his father's hips tightened, his fingers digging into the slick, sweaty skin, his nails leaving small, half-moon marks that were quickly filled with blood. He pulled Michael closer, his body aching with the need to claim, to conquer, to make him his own. "You're mine, Dad," he growled, his voice a low, primal rumble. "All mine. No one else can have you. No one else can fuck you like this, can make you feel like this."

Michael's eyes widened in shock and pain, his body tensing as he felt his son's grip tighten, the pressure of his fingers almost unbearable. "Brandon, please," he gasped, his voice a low, desperate plea.

But Brandon had already pulled out, his massive, angry cock standing tall and proud between them, glistening with lube and his father's juices. It was a monstrous sight, over four feet long and thick enough to make even the most seasoned of size queens weep.

Without a moment's hesitation, Brandon shoved his father to the ground, sending him face-first to the cold, hard tile of the bathroom floor. He fell with a grunt, his limbs splayed out awkwardly, his ass raised high in the air, a perfect target for his son's imposing member. Brandon knelt behind him, his eyes wild with lust and possessiveness, his massive cock throbbing and pulsing with an almost animalistic hunger.

"Dad," he growled, his voice thick with desire and dominance. "You're mine. Every inch of you is mine."

Michael moaned loud as Brandon slid his balls deep, knocking the air from his body as he began to jackhammer his cock into his dad's destroyed guts. The sheer force of the impact sent a fresh wave of pain and pleasure coursing through Michael, his body trembling and shaking with the effort to take it, to accommodate the relentless, brutal fucking.

He could feel every inch of his son's monstrous cock, the thick shaft splitting him open, the heavy balls slapping against him with each punishing thrust. The sound of flesh meeting flesh echoed through the room like thunder, a primal, feral sound that sent shivers of both pleasure and pain down his spine.

With each punishing thrust, Michael's body convulsed, his internal organs feeling like they were being rearranged, his body struggling to keep up with the relentless, brutal fucking. Michael's eyes rolled back, a low, guttural moan escaping his lips as his vision swam with waves of white-hot agony and ecstasy. The intensity of the sensation was overwhelming, his body trembling and shaking with the effort to accommodate his son's monstrous cock.

"Brandon... too much..." he gasped, his voice a low, ragged plea, his body wracked with pain and pleasure.

Brandon's cock throbbed, hungry for more, the relentless rhythm of his hips never ceasing. He could feel the heat of his father's body, the slickness of the lube, and the raw, primal power that coursed through him like an electric current. He was lost to it, driven by a hunger that was beyond his control, beyond his understanding. He needed more. He wanted more.

Brandon’s lips curled into a feral smile, his eyes glinting with a wicked excitement. "Good," he growled. "Because I’m not going to stop until I’ve filled every inch of you, until I’ve marked you as mine." His hand trailed down Michael’s back, the touch both gentle and demanding, before gripping his hip tighter, his fingers digging into the flesh as he thrust forward with renewed force.

Michael’s body tensed, his muscles stretching to accommodate the relentless invasion.

Brandon’s grip on his hips tightened, his nails digging into flesh, leaving bloody crescent-shaped marks. “You’re mine, Dad. All fucking mine,” Brandon snarled, his voice raw and primal, each word punctuated with a punishing thrust.

Michael could feel every vein on Brandon’s cock as it slid in and out of him, the massive shaft stretching him wider than he ever thought possible. His body was a ragdoll, completely at the mercy of his son’s insatiable desire. Every inch of him ached, burned, and trembled with the effort to contain the sheer force of Brandon’s cock.

His vision swam with wave after wave of agony and ecstasy, the lines between pain and pleasure blurring until they became one and the same. Michael’s body was a wreck, his muscles taut and quivering, his breath coming in ragged, desperate gasps. But he couldn’t stop, couldn’t give in to the exhaustion that threatened to consume him. Not yet. Because Brandon was still fucking him, still driving his massive, monstrous cock into his guts with a force that was almost superhuman.

Brandon’s grip on his hips tightened, his fingers digging deeper into the flesh, leaving bloody crescent-shaped marks in their wake.

He was lost to the raw, primal power that consumed him, his body moving with a relentless, brutal force that was almost inhuman. The sound of flesh slapping against flesh filled the room like the rhythmic beat of a war drum, each punishing thrust sending a fresh wave of pain and pleasure through Michael’s body.

“Fuck, Dad,” Brandon grunted, his voice thick with lust and dominance. “You’re so fucking tight. So fucking perfect.” He looked down at the massive length of his cock sliding in and out of his father’s guts, the sight sending a fresh surge of heat and power coursing through him.

He felt like a god, a primal, insatiable force that consumed everything in its path. His cock throbbed, the veins standing out like ropes, the massive head stretching his father's hole to its absolute limit.

He reached down, his fingers tapping gently against the base of his enormous organ, feeling the heat and the power that radiated from it. The sight of his cock, the heat and the throb, sent a fresh wave of desire coursing through him, his hips moving faster, his body driven by a raw, primal instinct that was beyond his control.

He felt a surge of power, of dominance, as he claimed his father’s body, as he stretched him wider, filled him deeper than anyone else ever had. His fingers trailed down the length of his cock, the veins standing out like cords against the thick, glistening shaft. He felt the weight of his massive balls, the heavy orbs slapping against his father’s flesh with each punishing thrust. He could feel the heat of his father’s body, the slickness of the lube, the raw, primal power that consumed him like a wildfire.

“Fuck, Dad,” he growled, his voice a raw, guttural rumble.
