Best Buddies; Justin's Origins
"Bye bye sweetie, we'll see you in a few days"
The cream colored mare said with a loving kiss to her son's forehead.
"try not too wreck the house, but if you do, don't leave any evidence"
His father added with a wink and a smirk.
"alright guys, OK just go already, you'll miss your flight!"
the young 17 year old replied to his fussing parents, trying to get them to leave him in piece.
Eventually they left and the young brown stallion was left alone in the family home. He watched and waved from the living room window as the 4X4 drove out of sight.
"finally, 3 days to myself!" Justin thought to himself as he wandered what to do with the abundance of freedom he had just gained. A movie day sounded like a good idea, but first he needed to freshen up.
Whilst turning on the shower and waiting for it to reach the ideal temperature, Justin admired his naked form in the mirror. Light brown all over and standing at a modest height of 6ft 4". A slim but toned physique meant he had visible biceps, a feint set of pecs and decent abs. As he stood there waiting, his eyes obviously drifted lower to between his thigh's, a black leathery sheath rested there, about 4 inches across, the head of his equine cock just visible in the folds, mottled pink and black. He gave his softball size balls a weigh with one hand and smiled a confident smirk, he was proud of his male hood.
And he had every right to be, he knew he was big where it counted, 14 inches long and around 5 thick when hard. These adult thoughts raced through his mind as his sheath began to stir and swell, his shaft slowly peeking out from his sheath. The long brown horse cock slowly rose to it full hard length, and Justin's hands quickly grasped at the length, stroking and caressing every inch.
As the steam from his forgotten shower slowly filled the modest bathroom he continued his self pleasure, his left hand gripping the base and the right rubbing the head and shaft. Moans and grunts filled the air as he worked himself to another euphoric high. Hands moving faster and grips getting tighter his balls rose and contracted, swelling slightly in preparation for the end result. Pre-cum dripped from the head of the flaring, steel hard horse cock onto the floor below, making a slick puddle below Justin hooves.
The young stallion staggered as his teenage lust-addled brain focused on the pleasure emanating from his pulsing flesh, his muscles flexing harder as he worshiped his manhood. He moved to aim his cock head at the sink in front of him, pushing it down ready for what he knew would be a big cumshot, having abstained for 4 days before hand. But as he moved a hoof to get a better stance, it slipped on the puddle of pre-cum he had made, losing his balance his hands flew to the bathroom shelf for a handhold, knocking off various sundries and bottles. Most of them flew to the floor as he finally got a grip and steadied himself, his rock hard cock still pulsing from his groin and leaking a steady stream of pre-cum onto the counter.
"DAMMIT" Justin grunted in annoyance, bending down to pick up the various sundries from the floor, deciding to forget about his pleasurable pursuits for the moment. After finally clearing the floor of derbies, standing and placing them back upon the shelf, he noticed a small pill bottle lying in the basin before him. The label read 'Hyperized Production Boosters' and beneath in smaller print where the words 'take 2 daily'
With a glint in his eye, he rubbed a hand along his still hard 14" horse cock and wandered if these could be the genuine article. With a grin and a new plan for the day ahead, he decided to shower for the sake of it, his cock leading the way and his hand idly stroking the flesh.
Justin decided not too finish himself off in the shower, wanting to save the experience for a place where he could watch the events unfold.
After a very quick shower he towelled himself dry, his cock still hard and swinging like a metronome between his legs, his hands occasionally wandering down to stroke the brown meat and fondle his soft ball size testicles. The young brown stallion made his way to his bedroom, the small bottle of pills in his hand, and a lustful grin on his lips. Sitting down on the end of the king size bed, he unscrewed the cap and took out two small pills, dry swallowing them quickly. Moving back up the bed and lying down, he wrapped both hands around his meat, stroking and wandering how long, if at all, these pills would take to begin.
He didn't have to wait long at all, as he stroked his 14" of horse cock, he felt a light warmth overtake his body, his muscle's clenched and his cock went harder than he'd ever known before, throbbing like a thing possessed, veins popping out all over as the blood flow increased like he was wearing a cock ring.
"Ohhh Fuck" moaned Justin.
His hands gripped tighter and moved faster as the flow of precum turned into a steady stream, flowing down the throbbing meat and onto his taught balls below. Then he felt it, his cock throbbed and his hands were forced wider apart, no longer able to touch, his cock rose slowly further away from his groin. Adding inches per minute to the thick brown meat, he stared wide eyed as he came to the realization that his cock was actually growing before him, stretching to 16 inches then 17, 18 and still throbbing larger.
When the warmth finally left his body and the throbbing growth stopped Justin was left panting and groaning on his bed, staring at a 20 inch monster cock, and best of all it was his monster cock. He sat up, his hands still working his meat slowly, not even able to meet around the 7 inch girth. Then his eyes fell upon his balls, each one had swelled from soft ball size to near grapefruit size, his production of precum more than he'd ever felt before. He could feel it being pumped through his rock hard cock, sliding down over his hands and massive ball sack and onto the bed sheets below, thoroughly soaking them.
This was fucking awesome he decided, and he quickly threw all caution to the wind, grabbed the bottle and downed another 5 pills dry. He wanted more of this, he wanted to be the biggest horse of them all, to cum more than anyone thought possible. The heat struck quicker this time, but it was everywhere, not just in his cock, for a second before the pleasure of growth hit him, Justin worried he might have over done it.
But that thought was quickly silenced as the throbbing returned, his cock shot up past 22 inches in under a minute, soon reaching 24, his hands being pushed ever wider apart. He could see his balls rising from behind his pillar of meat, getting steadily larger, rising higher and higher, until they looked to be the size of basketballs. The thought of how much cum was stored in his huge testicles only drove his hands faster over his growing flesh.
The throbbing monster of a horse cock now rose from his groin like a monolithic pillar of masculinity, 26 inches long and a massive 9 around, Justin writhed and moaned as the pleasure from his ministrations flooded his teenage brain. The warmth in his meat soon subsided from a furnace to a steady fire, only fueling the lust he felt, the growth slowed as his cock reached a staggering size of 28 inches long and 12 around. The flow of precum now a river as it spat and ran from his flaring cock head.
His hands worked faster, his hooves dug into his massive beach ball size testicles and massaged them, the feeling of the cum sloshing and churning too much to bear for the overloaded teenage horses brain. With a ear shattering Whinny and a final thrust into his over taxed grip, his cock exploded in a torrent of white. It shot from the flared head, and ricocheted off the ceiling above, splashing and coating everything in sight in a thick film of hot steaming horse cum. The cum cannon continued to fire as the attached horse writhed and moaned, almost blacking out from the sheer pleasure of such a massive cum shot.
As cum continued to shoot from his cock, somewhere in Justin's overloaded brain he registered the fact that his body was heating up. However in the midst of such a titanic orgasm this was quickly and figuratively washed away. But he did heat up, his muscles clenched and throbbed, growing bigger with every spurt of cum that left the still firing cock. His biceps grew from slightly noticeable to shredded in seconds, as did his pecs, his decent set of abs grew to a set of brick wall abdominal's, and his leg muscles throbbed to tree trunk thick power houses. None of this could be seen of course as the cum continued to rain down on the now muscle ridden 17 year old stallion.
The mind shattering orgasm finally came to a close ten minutes after it had began, ten minutes of pure unadulterated bliss. The cum level in his small room had rose to be level with the bed, and sloshed warmly at his sides. Justin noticed the warm feeling tickling on his now shredded body and with a dumbstruck grin on his face, promptly passed out.
The small bottle of pills floated next to his side in the lake of cum that was his room, rolling over and displaying a large triangle with an exclamation mark in the middle, it revealed some fine printed text; 'overdose may result in permanent and undesired muscle growth as-well as permanent penile and testicular enhancement.'
Justin awoke the next morning to find a log of horse cock draped over his leg and a lake of cum in his room , and after a day of pouring cum down the toilet, cleaning carpets and generally doing a monster size deep clean. He came to the realization that you should always read the fine print.
