THE HIKE

Steve had always been athletic. He enjoyed working out, biking and best of all 
hiking. All the activity kept him lean and muscular. His 6' frame was handsome, 
he had 16" arms and a broad, 46" chest. He was by no means a bodybuilder, 
although in his fantasies he had always wished to become a "freak". He knew at 
34 years of age, he'd probably not make the Mr. Olympia championship, but it 
never deterred him from striving to be his best.

Distraught over the breakup with his girlfriend, Steve found himself hiking in 
the woods. Lost in the thought and enjoying the time away "from it all", he had 
hiked for 2-1/2 hours. Realizing the time, he was happy to have put in a great 
workout, but at the same time was concerned that the afternoon had quickly 
turned to early evening and that he was at least 10 miles into uncharted 
territory. He hadn't seen a trail marker for some time and realized that there 
was really no evidence of human traffic of any kind. The air quickly became 
chilly and Steve's tank top wasn't going to protect him from a really miserable 
hike back. After 20 minutes of trying to retrace his steps Steve realized he was 
lost. Frustrated and concerned he realized that he'd better find some shelter 
quickly and find safety from the cold night air and the wolves howling nearby. 
Walking near a grove of old redwoods, his foot fell into a hole. As he struggled 
to pull his leg out, his motions loosened the soil around him and he fell into 
darkness. The clouded night sky provided no light from above and the complete 
darkness offered no comfort sake for his lack of injury. He dusted himself off 
and pulled a match from his backpack and started a small fire. The flame's glow 
illuminated a spectacle that caught Steve by surprise.

He stood awestruck as he looked slowly around the cavern to find ancient 
paintings on the cave walls and ceilings. Huge beasts were everywhere, immense 
frightening images of monsters which were beyond comprehension in terms of 
muscular size and apparent strength. As Steve studied the paintings he realized 
that these beasts were not animal but instead, more like "super" humans. The 
chalk drawings accurately showed freakishly huge shoulders, necks and arms. 
Pectorals appeared to be like boulders and abs like bricks. Most shocking were 
the "men's" immense members. Their cocks were beyond belief. In fact, Steve 
convinced himself that he was not witnessing an archeological treasure but 
instead graffiti by a perverted, albeit, hot juvenile artist.

Although made horny by the spectacle, Steve's sense of self-preservation got him 
on track to building a small fire and seeking some type of nourishment. The cave 
had some water dripping from above which addressed his thirst but Steve was also 
starved, having not eaten food since breakfast. Searching the cave for anything 
that resembled food, Steve found some berries in the debris near where he had 
fallen. They must have come down with him. They looked perfectly edible so he 
gathered a handful and quickly consumed them. Hardly satisfied, he continued to 
walk through the narrow cavern, again coming across berries. Their bright red 
shade was beautiful and they had been delicious, but these were apparently 
growing, no, thriving in the deep darkness of this pit he found himself in. 
Botany was hardly of concern, he had to feed his hunger and the huge growth of 
berries would satisfy Steve until morning. He quickly consumed the supply and 
felt very content, but a little dizzy. It must have been the day's excitement, 
so Steve returned to the fire and laid on the ground thinking about the day.

As he looked at the ceiling at the huge freaks all around him, Steve's vision 
began to double and blur, his heart began to pound and he felt an aching 
throughout his body. He'd never felt that way, Steve was alone, cold and in 
near-pitch darkness, he was scared for his life; when the change began.

The pounding of his heart intensified and Steve began to sweat uncontrollably. 
His limbs felt as though they were being flooded with blood. He began to whimper 
as his head pounded and his stomach felt like it was about to rip open. Keenly 
conscience of his agony, Steve realized that the berries must have been 
poisonous. He tried to stand up and find water to flush his system but his legs 
and arms were immobile. As Steve stared at the ceiling in a silent panic, tears 
ran down his cheeks He knew he was about to die. His arms and shoulders felt 
like they were being ripped about. He felt his tanktop pulling and binding into 
his flesh. His legs were flailing as an intense heat fired through every inch of 
his body. His vision turned red as sweat pours onto the cave floor. The 
intensity worsened and it seemed like an eternity when suddenly it came to an 
abrupt end. He quickly felt his body cool in the cave air and his body felt 
strangely pumped. In fact he now felt an intense sense of relaxation. But he 
also felt a stirring in his jeans, a sensation like he had never experienced, 
not even with his girlfriend, that was no longer in his thoughts.

He was able to lift his right hand over his forehead and sighed in relief. The 
pounding heart had slowed, the stomach pains were gone and he could once again 
move his arms and legs. Still trembling, he got up and walked to the dripping 
water from the hole above. As he cupped his hands to reach for a few drops of 
water, the full moon beamed light onto his forearms. Steve's eyes nearly bugged 
out when he saw the thick and gnarly veins covering his arms. He'd always had a 
few small veins showing from years of lifting weights, but these were unlike any 
he had pumped in the gym. He slowly glanced at his biceps and saw the thick 
veins crawling all the way up to his shoulders. Fear took over again, as he 
looked at his chest and legs, his body no longer looked clean and smooth. 
Steve's entire body was covered in thick veins, he had never witnessed such a 
tortured body. As he felt the deformations under his flesh gain in size, his 
body tensed and hardened, the pounding began once again. But this time Steve 
could witness what the pain was imparting to his body. A swelling of muscles 
commenced, his legs were ballooning as he stared in disbelief, his arms exploded 
into monstrous 19 inch guns, than 20 and finally 22 inch monsters. As he gasped 
for air, his entire body was transforming into a freakish imitation of the 
painted walls. His mind was out of control, he was drowning in fear but at the 
same time, turned on beyond belief. His cock had initially shrunk as he feared 
for his life, but as he began to revel in the transformation, his meat was also 
turning into a monster of sorts. His cock head was like a grapefruit and the 
mighty shaft looked like a baseball bat as it ripped through his jeans. His tool 
was oozing pre-cum as he flexed and pounded his mighty feet into the ground.

Suddenly the change was over, Steve was no longer the man he once had been. 
Within minutes, Steve had become a 350# muscle freak. His entire body was 
trapped in a layer of veins, thick and visibly throbbing. His arms were 
frighteningly huge and connected to immense shoulders. His neck's thickness was 
greater than his head and his quads made walking a difficult new skill to 
master. Most incredible, was his cock, its immense size required an incredible 
blood supply to maintain and dominated Steve's thoughts. It was as though his 
brain's ability to reason and think were lost and his cock was now providing his 
body with thought and consciousness. The few thoughts that he had were about the 
intense desire he had for his cock. Standing in the beam of moonlight, Steve 
became acquainted with his new body, he flexed every muscle continuously and 
stroked his cock with ritualistic drive. He never thought of how he would return 
to civilization, how he would find food, or where he would sleep; his cock was 
his master and he needed to satisfy its desires. Pounding his immense tool with 
both vein-covered hands he shot a load so thick and powerful that it echoed 
through the cave. The blast pounded the cave wall and splattered back onto his 
body. Rubbing the juice back into his flesh, Steve instinctively realized that 
this would be his food source as well. Deep in the recesses of his mind, he knew 
to lick the cum from his hands and gulped what he could from the puddle near the 
wall. Never before had he craved his own man-juice, but something was 
instructing him to feed on it, he needed more cum, much more cum. The thought of 
consuming his juice would have disgusted the old Steve, but it is all he wanted 
or needed now. His cock never softened and he began the ritual again. He had 
positioned his empty water bottle near his monster dick and stroked his meat 
with his right hand, as his left pleasured his butt hole. Never a bottom, Steve 
realized the desire he had acquired, and fisted himself with no fear of injury. 
In fact he took no precautions as he tortured his nipples and cock until his cum 
exploded into the bottle. The force and intensity were stronger than before, and 
he experienced a drive he had never had. He eagerly raised the bottle to his 
eyes and witnessed the nearly gallon of white fluid that came from his new body. 
Amazed by the quantity and intoxicated by the desire, he lifted the bottle and 
enjoyed his cum as it went down his throat, eagerly sucking the bottle for every 
drop. The fluid quickly filled his insides and his limbs took on a heaviness as 
they grew slightly more. Steve felt this change immediately, it wasn't so much 
in growth as it was in power. Steve was now in possession of power beyond his 
wildest dreams. Power controlled by his cock, power that he had a hunger to use. 
Instinctively, he knew of its use, but he'd have to wait for morning before his 
cock would lead him through a journey, beyond the change.

As the sun filled the morning sky with light, Steve awoke from a sleep filled 
with images of muscle and cock. He laid in a pool of cum, his monster prick had 
been shooting all night and his dreams had made him want to grow even more. 
Standing up from where he slept, Steve realized that this new body wasn't a 
strange fantasy, the reality set in. Steve momentarily experienced some anxiety 
as he wondered what life would be like, but quickly changed his thoughts as he 
began to flex and rub the puddle of cum into his hard flesh. He leaned down into 
the puddle and eagerly drank us much of his own man juice as he could retrieve. 
His body filled with a sense of strength and power again. He knew his mind was 
not in charge. He had never spent so much time in the past thinking about sex, 
and he certainly never enjoyed cum at all. He'd been an average straight guy who 
never experimented much. But now he was driven by an incredible desire to use 
his body to achieve ultimate sexual pleasure. He realized that everything he 
wanted was gay, all he knew now was that he wanted more of it.

As he climbed up from the cave, he paused to look at himself in the daylight. 
His immense size was frightening and his cock was huge, almost 2 feet in length 
and a foot around. His vascularity made him horrible but at the same time, 
ultimately masculine. He was pure man-beast, he was beyond manhood, he loved 
every inch of himself. His body had definitely grown through the night. Steve 
would have jacked off, but he had a sense that he needed to use his cock for a 
different function. He had an incredible desire to mate. He moved quickly 
through the woods, back towards the trail. As he came across it, he positioned 
himself behind some brush, he laid there quietly for an hour, slowly stroking 
his cock and licking pre-cum. Suddenly, he heard voices, two women were walking 
down the trail. Their large breasts looked great under the T-shirts and both 
women were beautiful. But Steve saw nothing in them, as he once would have. 
Steve stayed hidden, when moments later his patience paid off. A tall guy, about 
6' came down the path, his muscular build was evident beneath his clothes. Steve 
noticed that his cock stiffened as he caught a glimpse of Ed. Momentarily, Steve 
was confused, he'd never been interested in men, but he had to admit that 
something had happened with the growth. The desires he had were not just for his 
own body, but for other men as well. Steve didn't feel queer, in fact he felt 
more masculine by his desire. He knew that this man would not get away, he 
wanted Ed and he was about to get him.

Ed was looking down the trail, as the brush moved and out of the trees launched 
a monster. He had only a split second to experience shear terror before the 
vein-covered beast trapped him in his huge arms. Ed didn't have a chance to cry 
for help as Steve ran with Ed in his arms, his cock pressed tightly against Ed's 
chest, oozing cum into his clothes. The two fell back into the cave, Ed was 
terrified and was certain of his death. As he struggled, the beast tied his arms 
and legs with scraps of clothing that remained from the change the night before. 
Ed was trapped and was finally able to witness what had grabbed him. Steve paced 
the room, his muscles preventing him from walking straight. Ed had never seen 
anything like him, he was twice the size of a Paul Dillett or Chris Duffy - type 
that Ed had seen in the Muscle Mags at the gym. He had also never seen a cock 
like the one that Steve possessed, he was disgusted by the size of it, and the 
pre-cum that constantly flowed from it. Even more gross to Ed, was the way the 
creature kept wiping it with his hands and licking the fluid. Ed stayed seated 
for hours, looking at the monster in both fear and disgust. Steve paced 
constantly, staring at Ed with hungry eyes, apparently not quite sure what to do 
with this man. Hours had passed, and Ed realized that no harm was intended, 
finally, Ed annoying said, "you got some food around here or are you planning to 
spend the day walking around?" Steve looked at Ed, waited a moment, and said, 
"I've got some berries, you want 'em". Ed responded back, "If that's the best 
you can do, I'd rather eat something than look at you all day, fuckin' freak". 
Ed had become angry by creature's constant pacing and he realized that the 
creature had no interest in harming him.

Steve brought over the last of the berries in his enormous hands, holding them 
near Ed's mouth. Ed quickly ate them all, and managed to thank Steve. Steve, 
replied, "no, thank you". But before Ed could ask what that meant, he felt a 
rush come over him. A dizziness filled his brain, and he could feel his head 
spinning. As he looked at Steve, it appeared that the monster was noticeably 
agitated, he began to aggressively stroke himself and began to pull off Ed's 
clothes. Laying naked, Ed looked with fear at Steve, his eyes were wide open and 
his face pale with fright. But suddenly, the change began to occur in Ed, he 
looked at Steve again, in fact he seemed transfixed by the muscles on his body. 
As Ed felt the intensity of what was happening, Steve began to shoot load after 
load of cum onto his victim's body. Steve saw the change occurring, Ed's eyes 
began to show a hunger, and as they did, Ed's mouth began to open. 
Instinctively, Steve knew this was the beginning of a mating process and that Ed 
was his chosen partner. As the berries took affect and Ed's body began to grow, 
he was untied, Ed's hands began to run over his growing body and his cock began 
to swell. Ed was terrified by the change but was also incredibly turned on by 
his and Steve's bodies. He was becoming a freak and the only reservation he had 
was that it wasn't happening fast enough. Steve commanded Ed to his knees and as 
he fell to the ground, Steve stepped forward and with both hands, caressed his 
huge organ. As he did, the head became a bright crimson, and the veins throbbed 
angrily. Just as Ed touched his lips to the cock, a huge explosion of cum filled 
his mouth and covered his face. The burst was so powerful it stung his face, but 
he eagerly kept accepting more and more. Steve leaned down next to Ed and licked 
his face and as Ed neared climax, Steve went down on his new mate. Steve 
experienced his first powerful burst of another man's cum, he enjoyed it as much 
as his own. The pair had exchanged their juice and both bodies felt the 
intoxication of the power and strength that came with it. The men laid in each 
other's arms, Steve feeling the heat emanating from Ed's body as it continued 
through the process that would turn him into a muscle monster like himself.

Within minutes, Ed's body had gone through the change and was now as terrifying 
as Steve's in appearance and size. As Ed pulled away from Steve, he surveyed his 
body, than Steve's and they both began to laugh. Both men were so turned on by 
each other that they stroked each other freely with no reservations. For Steve, 
it was wonderful to have someone to share the experience, but deep in his mind 
he realized that the mating process had yet to be completed. Unsure about the 
drive that he felt inside, he knew one thing. He had to fuck Ed, he wondered if 
Ed could receive his huge meat. But his thoughts were again quickly overwhelmed 
by the burning desire to mate. The damage he could do to Ed didn't matter, he 
knew that he had to fill Ed's insides with his cum and he had to begin right 
away. Ed was still experiencing the incredible sensations of his new body, when 
Steve whispered into his ear, "its time". Ed questioned the remark but was 
unable to fight off Steve, when Steve grabbed his tight waist and pulled him 
closer. Steve's huge cock appeared enraged, its savage vascular appearance was 
even more horrid because of its purple color. Ed protested loudly as Steve's 
huge head began to press against Ed's ass. Ed hadn't had enough time to grow and 
was still weaker than Steve. Steve plunged his member into Ed's virgin ass and 
Ed screamed in horror. As Ed struggled in utter pain he also experienced the 
warmth of being impaled by the huge rod. As the pumping became rhythmic the pain 
was quickly replaced by shear pleasure. In fact, Ed began to pulsate with Steve, 
wanting more of the huge monster dick in him. Steve knew it wouldn't be much 
longer, he was experiencing utter pleasure but still wondered why this act was 
instinctively so important. Then it happened, Steve felt his whole body stiffen, 
his cock became rock hard and he exploded cum into Ed's insides. He pumped and 
continued to pump with no end for several minutes. The cum wouldn't stop and 
Ed's ecstasy was constant, he scream than growled like an animal. As Steve 
finished his climax he pulled away from Ed and let his huge meat drop to the 
ground, absolutely satisfied, in fact it was the first time his cock had been 
satisfied since the change. He sat back on the ground and looked at his mate, Ed 
laid face down on the ground, his huge glutes were beautiful, cum dripping from 
between them. As Steve sat watching his friend's massive back he was startled by 
what he witnessed.

Ed began to grow again. Steve hadn't thought that the human body could carry 
more muscle than they both possessed, but as he watched, he saw the lats and 
traps thicken to an unbelievable size with incredible speed. Ed's arms were 
beyond anything he had ever seen. Ed was transforming from freak, to monster, to 
creature. As the growth continued, Ed rolled over and exposed a cock that more 
massive than Steve's. Its head was at Ed's mouth and he took full advantage by 
licking the constantly flowing pre-cum. Steve called to Ed, but there was no 
response, Ed nursed on his cock and flexed and enjoyed every body part. Ed's 
eyes were transfixed, they were empty now, he was possessed with the need for 
sex and nothing could take his attention away. Ed no longer had thoughts of any 
kind, he simply needed to fulfill his sexual desire. Steve realized the outcome 
of the mating process, he knew now that one's mind would be lost as a result. In 
fear of meeting the same end, he got onto his feet and began to back away from 
Ed. It was too late, Ed knew his role in the mating process, and it was his 
turn. As Steve attempted to flee, his mind was conflicted, he had witnessed the 
enormity of Ed's body and wanted the same, but he also wanted his mind. Luckily, 
Steve's concerns wouldn't last for long, Ed's cock head had already entered 
Steve's ass, seconds later Steve felt the rush of cum flowing through him, his 
body filled with heat, he was incredibly aroused by the sense of new growth, an 
instant later his mind went blank.

Both Ed and Steve were like zombies wanting only sex from life. Their blank eyes 
showed no thoughts except for an incessant desire for sex. Their bodies had 
grown increasingly large from the injections of each other's semen. The new 
found muscle kept them constantly hard, both flexing, posing and stroking for 
each other. There was no stopping for rest, they knew their muscles could 
continue growing if they fucked each other and filled their insides with cum. So 
they took turns throughout the night. The cave was filled with screams of 
pleasure and grunting like monstrous animals as they both climaxed over and over 
again. As the night progressed, the two beasts showed no signs of tiring, in 
fact, as they continued to become more monstrous, the sex between them became 
more savage. Each one pounding the other harder and harder. The cave stunk from 
the constant sex. Pools of cum covered the floor, both men eagerly drank as much 
as they could, but the constant eruptions filled the cave floor. The heaving 
bodies were covered in sweat and the rank smell added to the desire both animals 
had for each other.

As morning arrived, the growling continued, but the new day's light was rapidly 
filling the cave. They were truly able to witness what the cum had done to them. 
The moon's glow previously provided only a hint of what they were now witnessing 
in daylight. They had become horribly disfigured by the huge muscular growth. 
Their tiny 30 inch waists appeared to be burdened by the outrageously huge 
chests, both nearing 70 inches in diameter. Their arms stuck out as their 
enormous lats pressed them away. Their biceps were 40 inches and still growing. 
Neither man was human anymore, the beastly bodies were for sex and nothing else, 
they didn't even have the need to hunt like a primate. They seemed to thrive on 
a diet of pre-cum and a load of ejaculation in their insides. Their vocabularies 
had decreased to only the most necessary of terms, "fuck me". But also with the 
day's light, another change was revealed. What had been a night of showing off, 
fucking and pure masculinity was know taking on another shift. For the first 
time since the two had begun the change, their eyes met in the light, and the 
look of desire was now replaced with a look of love. Both men had become 
homosexual in every inclination, they only needed and wanted cock. Luckily for 
them, they had the largest, most angry cocks available to show that love.
