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 5: Mastering the Pump

Michael held up the clear plastic cylinder, the afternoon light catching its smooth surface. "Alright, so this is it," he said, his voice steady but with a hint of curiosity. "Pretty simple, really. Lube it up, slide it on, and start pumping." He glanced at Brandon, who was sitting on the edge of the couch, his hands clasped tightly. "Just don't go too hard too fast, alright? We don't want you bursting any blood vessels."

Brandon took the pump, his fingers tracing the smooth plastic as if it were some kind of forbidden artifact. "So, just like...a vacuum for my dick?" he asked, a nervous laugh escaping him, his voice cracking slightly. Michael chuckled, leaning back in his chair, his arms crossed. "Basically, yeah. It'll draw blood into the area, make it swell up." He paused, raising an eyebrow. "Some guys swear by it. Others think it's a load of crap. Guess you'll have to find out for yourself."

Brandon retreated to the bathroom, locking the door behind him with a soft click. He stared at his reflection in the mirror, his heart pounding in his chest, a mix of excitement and trepidation swirling within him. "Alright, Brandon," he muttered to himself, his voice barely above a whisper. "Let's see what this thing can do." He unzipped his jeans, pulling them down along with his boxers, his cock already half-hard from anticipation.

He followed Michael's instructions, coating his cock with a generous amount of lube, the cool gel making him shiver slightly. Carefully, he slid the cylinder over it, the fit snug, almost uncomfortably so. He gripped the pump, taking a deep breath, his hands trembling slightly. "Here goes nothing," he whispered, his voice barely audible over the sound of his own heartbeat.

With the first pump, he felt a strange sensation, a slight pressure building around his cock, like a gentle squeeze that wasn't entirely unpleasant. He pumped again, and again, watching in fascination as his cock began to swell, the head darkening, the veins becoming more prominent, pulsing with each stroke of the pump. "Holy shit," he breathed, his voice filled with awe. "This thing actually works."

He paused, his heart pounding, a wave of dizziness washing over him, his vision blurring for a moment. He glanced at the small pressure gauge on the pump, making sure he wasn't exceeding the recommended level, his fingers gripping the handle tightly. "Woah," he whispered, his voice filled with awe. "This is...intense." He continued pumping, slowly and steadily, his cock growing larger and larger with each stroke, the pressure building, almost painful, but he couldn't stop, his eyes glued to the sight of his engorged cock.

He glanced at the clock on the wall, realizing he'd been pumping for almost fifteen minutes, the time slipping away unnoticed. He decided to stop, releasing the pressure valve with a hiss, the sound sharp in the quiet bathroom. The cylinder slid off easily, revealing his cock in all its swollen glory, the veins bulging like ropes, the head engorged and dark. "Holy shit," he breathed, his voice filled with disbelief. "I'm huge."

He measured himself, his hands shaking slightly as he held the tape measure against his cock, his eyes widening as he read the numbers. Eleven inches. He was eleven inches hard, the tape measure barely able to stretch to accommodate his newfound size. He'd never been close to that before, his previous measurements paling in comparison. A surge of pride washed over him, followed by a wave of nervousness, his mind racing with thoughts of what he would even do with all this.

He heard a knock on the bathroom door, the sound jolting him out of his thoughts. "Brandon? You okay in there?" It was Michael, his voice calm but with a hint of concern. "Yeah, Dad, I'm fine," he replied, trying to keep the excitement out of his voice, his heart still pounding in his chest. "Just...experimenting." He quickly cleaned up, pulling his pants back on, his cock still throbbing, the feeling almost overwhelming.

He walked back into the living room, trying to act casual, but he could feel Michael's eyes on him, assessing him, the weight of his gaze almost palpable. He sat down on the couch, trying to avoid eye contact, his hands clasped tightly in his lap. "So," he said, clearing his throat, his voice slightly hoarse. "What's for dinner?" He glanced at Michael, who was still watching him, a small smirk playing on his lips.

Michael chuckled, shaking his head, his eyes twinkling with amusement. "You seem...taller," he said, his voice teasing, the smirk widening. Brandon blushed, shifting uncomfortably on the couch, his hands gripping the edge of the cushion. "It's just the shoes," he mumbled, trying to deflect the attention, his voice barely above a whisper. He glanced down at his feet, as if the shoes could somehow explain the sudden change in his posture.

Michael chuckled again, leaning back in his chair, his arms crossed over his chest. "Alright, alright," he said, his voice light but with a hint of curiosity. "Let's eat. But after dinner, I want to hear all about this 'experiment' of yours." Brandon swallowed hard, a mix of anticipation and dread churning in his stomach, his heart pounding in his chest. This was going to be an interesting night.

Brandon shoveled forkfuls of spaghetti into his mouth, barely chewing before swallowing, the noodles sliding down his throat in a messy rush. "Gotta...tell you...something...after," he mumbled between bites, his voice muffled by the food, his eyes fixed on his plate as if it held all the answers. His heart raced, the anticipation of what he was about to reveal making his hands tremble slightly. He twirled another forkful, the sauce dripping onto the table, oblivious to the mess he was making.

Michael watched him with a bemused expression, twirling his own fork lazily, the noodles winding around it in a perfect spiral. "Easy there, son," he chuckled, his voice low and steady, a contrast to Brandon's frantic energy. "It's not going anywhere. Though, I'm definitely intrigued by this 'experiment' of yours. Sounds like you had a breakthrough." He winked, the corners of his eyes crinkling with amusement, and Brandon felt his cheeks flush, the heat spreading down his neck.

The front door swung open, and Sarah breezed in, her presence filling the room with a sudden burst of energy. "Hey boys! Smells delicious. Mind if I join you?" she asked, though she was already pulling up a chair and reaching for the extra plate Michael had instinctively set out. She twirled a forkful of spaghetti, the noodles winding around it effortlessly, her eyes darting between Brandon and Michael. "So, what's all this about experiments?" she asked, her voice light but laced with curiosity, her gaze lingering on Brandon.

Brandon choked on his water, the liquid spilling down his chin as he coughed, his face turning a deep shade of red. He shot Michael a panicked look, his eyes wide with desperation, silently pleading for him to change the subject. Michael just grinned, leaning back in his chair, his arms crossed over his chest, clearly enjoying Brandon's discomfort. "Oh, just a little something Brandon's been working on in the bathroom," he said, his voice teasing, the words dripping with innuendo. "Seems he's discovered a new way to...enhance his physique."

Sarah raised an eyebrow, her gaze shifting between Brandon and Michael, a knowing smile spreading across her face. "Oh really?" she purred, her voice low and sultry, her eyes sparkling with intrigue. She leaned closer to Brandon, her elbow resting on the table, her chin propped up on her hand. "And what exactly does this enhancement entail? Bigger muscles? Better stamina?" Her gaze dropped to his lap for a brief moment, her smile widening, and Brandon felt his stomach twist.

Brandon pushed his plate away, the half-eaten spaghetti suddenly unappetizing, his hands clammy as he reached for his water glass again. "It's...complicated," he stammered, his voice cracking slightly, his mind racing for a way to escape the conversation. He glanced at Michael, hoping for some kind of intervention, but Michael just shrugged, his smirk deepening. "Well, why don't you show us, son?" he suggested, his tone casual, but his eyes held a glint of challenge. "After all, a picture is worth a thousand words, right?"

Brandon's eyes widened, his heart leaping into his throat, the room suddenly feeling too small, too hot. Show them? Now? He hadn't planned on this, hadn't even considered it. But the challenge in Michael's eyes, the curiosity in Sarah's gaze, was too much to resist. He stood up abruptly, the chair scraping loudly against the floor, his voice trembling slightly. "Okay, fine," he said, his voice barely above a whisper, the words catching in his throat. "But you have to promise not to laugh." He turned and headed towards the bathroom, his mind racing with a mixture of fear and excitement.

Michael and Sarah exchanged glances, a silent understanding passing between them, the air thick with anticipation. Michael leaned back in his chair, his arms crossed, a smirk playing on his lips. Sarah twirled another forkful of spaghetti, her eyes sparkling with amusement, her smile widening. Neither of them said a word, but the tension in the room was palpable, the silence heavy with unspoken thoughts.

Brandon locked himself in the bathroom again, the door clicking shut behind him, his hands shaking as he reached for the pump. He stared at his reflection in the mirror, his face flushed, his breathing shallow. "Alright," he muttered to himself, his voice barely audible, the words more for his own reassurance than anything else. "Let's do this." He lubed up again, the cool gel sending a shiver down his spine, the cylinder sliding over his already throbbing cock, the fit even tighter than before, the pressure almost unbearable.

He gripped the pump, his knuckles white, his breathing ragged, his eyes fixed on the pressure gauge. He started pumping, slowly at first, the sensation strange but not unpleasant, the pressure building around his cock. His eyes widened as he watched his cock swell, the head darkening, the veins becoming more prominent, throbbing with each stroke of the pump. "Holy shit," he breathed, his voice filled with awe, the disbelief evident in his tone. He pumped harder, faster, the pressure increasing, the sensation almost overwhelming, his vision blurring for a moment.

As he pumped, his thoughts drifted to Michael's cock, the memory of its size and power fueling his determination. He wanted to surpass him, to prove that he could be just as big, just as dominant. He pumped harder, faster, pushing himself to the limit, his body trembling with effort, the veins on his cock bulging like ropes, the head throbbing with a life of its own. Finally, he reached a point where he couldn't pump anymore, his cock stretched to its absolute maximum, the pressure almost unbearable.

He released the valve, the cylinder sliding off with a wet slap, revealing his cock in all its monstrous glory, the size of it almost comical. He looked at himself in the mirror, his eyes wide with disbelief, a triumphant grin spreading across his face. He was ready to show them, ready to unleash the beast. He took a deep breath, his heart pounding in his chest, the anticipation almost unbearable. He unlocked the bathroom door, stepping out into the hallway, his cock throbbing with every step, the weight of it almost too much to bear.

Michael and Sarah turned to look at him as he entered the room, their eyes widening as they took in the sight of his engorged cock, the sheer size of it almost unbelievable. Michael let out a low whistle, his eyes gleaming with approval, a smirk playing on his lips. Sarah's mouth fell open, her eyes wide with shock, her hand flying to her mouth to stifle a gasp. "Holy shit, Brandon," she whispered, her voice trembling slightly, the awe evident in her tone. "You weren't kidding."

Brandon stood there, his chest heaving, his cock throbbing, the weight of their gazes almost too much to bear. He felt a surge of pride, of power, the triumph of surpassing his father, of proving himself. He looked at Michael, his eyes locking with his, a silent challenge passing between them. Michael's smirk widened, his eyes gleaming with approval, and Brandon felt a surge of confidence, of dominance. He was ready to take control, to show them what he was made of. The night was just beginning.

The room was heavy with the scent of sweat and sex, the air thick with unspoken tension. Brandon stood there, his cock still throbbing in his hand, a mix of pride and defiance in his eyes. Michael’s gaze was locked on him, the measuring tape dangling from his fingers, his expression unreadable but intense. “Let’s see what you’ve got,” Michael said, his voice low and steady, a challenge simmering beneath the surface.

Brandon’s chest rose and fell as he stepped closer, his cock glistening in the dim light, the veins pulsing with every heartbeat. He felt a surge of anticipation, the weight of Michael’s scrutiny both unnerving and electrifying. “You sure you’re ready for this?” Brandon asked, a smirk tugging at his lips, his voice dripping with confidence. He knew he’d surpassed his father’s size, and the thrill of that knowledge was intoxicating.

Michael’s eyes narrowed, a flicker of amusement in his gaze as he knelt down, the measuring tape in hand. “Don’t get cocky, kid,” he muttered, his tone casual but edged with something darker. He wrapped the tape around the base of Brandon’s shaft, his fingers brushing against the sensitive skin, sending a jolt of electricity through Brandon’s body. “Twelve inches,” Michael announced, his voice calm but with a hint of something unspoken, his eyes flicking up to meet Brandon’s.

Brandon’s breath hitched, his cock twitching in Michael’s grip, the validation sending a rush of heat through him. He straightened his back, his chest puffing out slightly, a mix of pride and arousal coursing through his veins. “Told you I’ve been working on it,” Brandon said, his voice steady but with a hint of smugness, his eyes locked with Michael’s. He could feel the power in his size, the way it commanded attention, and it thrilled him.

Michael stood slowly, his eyes never leaving Brandon’s, the measuring tape still in his hand. He stepped closer, his chest brushing against Brandon’s, the heat between them palpable. “Impressive,” Michael said, his voice low and gravelly, his breath hot against Brandon’s skin. “But let’s see if you can back it up.” He reached out, his hand wrapping around Brandon’s cock, his grip firm but teasing, his thumb brushing over the sensitive head.

Brandon’s knees nearly buckled, a low groan escaping his lips as Michael’s hand moved with practiced precision. He could feel the roughness of his father’s calloused fingers against his sensitive skin, the sensation both overwhelming and intoxicating. “Fuck,” Brandon muttered, his voice strained, his hips thrusting forward involuntarily, his body responding to Michael’s touch. He could feel the tension building, the pressure coiling in his gut, his breath coming in short, ragged gasps.

Michael’s grip tightened, his fingers moving faster, his thumb pressing against the slit, sending sparks of pleasure shooting through Brandon’s body. “You like that, don’t you?” Michael asked, his voice a low growl, his eyes dark with desire. He leaned in, his lips brushing against Brandon’s ear, his breath hot and heavy. “Show me how much you want it.” His hand moved with a rhythm that was both punishing and exhilarating, his fingers teasing and taunting, driving Brandon closer to the edge.

Brandon’s head fell back, a guttural moan tearing from his throat as his body tensed, his cock pulsing in Michael’s hand. He could feel the pressure building, the heat pooling in his gut, his entire body trembling with the intensity of it. “Fuck, Dad,” Brandon gasped, his voice breaking, his hips thrusting forward, his cock throbbing with every stroke. He could feel himself teetering on the edge, the pleasure overwhelming, his mind consumed by the raw, primal sensation.

Michael’s grip tightened, his fingers moving with a relentless rhythm, his thumb pressing against the slit, sending Brandon over the edge. “Come on, son,” Michael growled, his voice rough and demanding, his eyes locked with Brandon’s. “Show me what you’ve got.” Brandon’s body tensed, his cock pulsing as he came, his cum shooting out in thick, hot spurts, his entire body shuddering with the force of his release.

The room was silent save for the sound of Brandon’s ragged breathing, his body trembling as he came down from the high, his cock still throbbing in Michael’s hand. Michael stepped back, his eyes dark with satisfaction, a smirk tugging at his lips. “Not bad,” he said, his voice low and teasing, his gaze lingering on Brandon’s flushed face. “But you’ve still got a lot to learn.”

Brandon’s chest rose and fell as he caught his breath, his eyes locking with Michael’s, a mix of pride and defiance in his gaze. He could feel the power in his size, the way it commanded attention, and it thrilled him. “I’m just getting started,” Brandon said, his voice steady but with a hint of challenge, his cock still throbbing in his hand. He could feel the tension between them, the unspoken competition, and he knew this was far from over.

Michael’s eyes narrowed, a flicker of amusement in his gaze as he stepped closer, his chest brushing against Brandon’s, the heat between them palpable. “We’ll see about that,” Michael said, his voice low and gravelly, his breath hot against Brandon’s skin. He reached out, his hand wrapping around Brandon’s cock, his grip firm but teasing, his thumb brushing over the sensitive head. “Let’s see if you can keep up.”

Brandon’s breath hitched, a low groan escaping his lips as Michael’s hand moved with practiced precision. He could feel the roughness of his father’s calloused fingers against his sensitive skin, the sensation both overwhelming and intoxicating. “Fuck,” Brandon muttered, his voice strained, his hips thrusting forward involuntarily, his body responding to Michael’s touch. He could feel the tension building, the pressure coiling in his gut, his breath coming in short, ragged gasps.
