#1 of The Host

So, it's been a long time since I've been active anywhere outside of my RP circle. Many of my Watchers probably will be confused to see me post anything Hah!

Well, this is the starting of a transformation story. Filled with a lot of exposition into a pornry adventure that -will- include a-lot of cock and ball growth, strange cum. And maybe a bit of pregnancy. Hell, even some m/f action. Though I don't intend for that to be the main focus. No, this will be mainly homoerotic in nature.

Keep in mind, it'll be a slow burn. Nothing will get to outrageous in the coming chapter. But we'll start to see the more furry elements there. For now, this is pretty tame and human.


All It wanted was a Host

Thomas stepped into his apartment, sighing heavily. The not-yet middle-aged man was down In the dumps. Nothing had been going for him for a while now. His currently ex-lover, Jason, had made it clear their feelings should be kept strictly 'business'. He felt he was currently hanging on by a thread at his management position in that lousy retail-store. Regional management was looking to downsize, and promote at the same time. So he was sure regional would probably set roots down in his branch. Thus taking on a one shift for the day management style and promote the senior manager of the store. Either letting him go completely or demoting him and in-turn, letting another undeserving employee under him go. Likely he'd have to them too as his last responsibility.

It had become a bit much for the tall, mid-weight man. Pushing his arms out on either side of the thin wall-hung mirror. He didn't like what looked back at him. Though he rationalized unless his darkest fantasies ever came true he never would. Truthfully what stared back at him was nothing shameful at all. Trim, dusty brown hair, kept neat and short at his neck and the sides of his face, let to grow grow out near the top of his skull so his bangs could curl over his forehead.

Calming blue eyes that looked a bit sunken due to his lack of a healthy diet. Dark rungs forming around them, getting darker day-by day. He had a rather long rounded nose, usually took a certain person to find it one of his attractive qualities, he was one of them. Regrettably thin lips, and smooth cheekbones that you couldn't really tell even existed. Tom sighed heavily, resting his forehead against the mirror. Fogging it with his breath.

He had no time to pity himself though. A loud shaking crash nearly knocking him off his feet jostled him to his senses. Grunting and looking around ,the tremble not even continuing past the initial shock. The firealarm pulled and the ringing started to deafen him. He could already hear people outside heading down the hallway. The tremble felt like it came from 'up', not down. He was on the second-to-top floor. Had been some sort of explosive device he was sure it would've made more of an impact to him.

Well, he wasn't -sure- but he thought he was logical in his thinking at least. He moved out into the hallway, dropping his bag to the floor. The residents around him already heading down, "702! C'mon, the firealarm man!" One of his neighbors yelled. Thomas grunted, moving out into the hallway to the stairs, staring at the people shuffling from the floor above. He was staring to the few people coming down, and knew the number of them was probably right. It looked like Ten for the four large suite apartments above him. All of them looked to be fine and without injury.

Thomas didn't like this, he moved up the stairs and quickly came to roof access, pushing the door open, he saw something smoldering. Almost like a water vapor raising off something. His eyes widened. A meteor!? He laughed a bit, rushing out near the unremarkable piece of space-rock.


Minutes before the door had opened, and it had seen it's first sign of life. It was rather... annoyed with it's predicament. The atmosphere from above felt like it would be easy to retain it's shape, but here it was, practically stuck underneath it's husk of a craft. It wouldn't have another chance at that in centuries in the least. Though it's choice was still valid, It appeared to have landed on a type-zero planet, organic life was growing up to it's apex before it's downfall. This would be a good time for it. Perhaps it could save the life and make it it's own, to repair and remake it's craft to find the planet it needed once more.

It rejoiced, it could feel another living organism close, sensing it's surroundings, it could feel the drum beat of life below it. It was currently more interested in the erratic movements of something that was absorb it though. Aha! The thing had landed on it! It moved the best it could to adsorb the information of one of the.... lower class inhabitants of the planet. IT felt pity that it's first encounter was not with the type-zero civilization, it wanted them, it would assimilate the knowledge the once-alive creature had, but it wouldn't absorb it's form, that would counter-productive.

It already knew how to look for food and feed anyway, it seemed that's all the interesting knowledge the being possessed. The vibrations f a heavy creaking nose caught it's attention. The ground below it was trembling as something approached fast. IT became excited, something -much- larger was interest in it.

It waited patiently for the being to get closer, and closer... so close. He could sense the form of the creature now, and knew for sure this bi-pedal apex predator was the among the class-zero civilization it was interested in.

It had arrived!


Thomas grunted in disgust, that vapor seemed to be coming from whatever it was it had just stepped in! Ew! Kinda gnarly, Thomas lifted his shoe to see whatever it was he stepped in. He couldn't really tell, but it made him feel incredibly unclean, and Thomas wasn't okay with that. Turning he took off his shoe and headed inside before the fire-department arrived, it was just a weird rock, nothing to evacuate for.

Back in his apartment, he threw the shoe against the wall, and took off the other. Letting it haphazardly knock against the other. Distracted by the knock to his door. Thomas moved to answer it, looking at the man in hazard-ware standing outside of his door.

"Sir, have you seen any smoke? Is anyone injured?"

"Uh, no, not at all sir. I believe the disturbance came from the roof though." He admitted.

"No smoke? No heat from your apartment?"

"None at all." Thomas leaned against the frame, looking outside. "Should I be leaving sir?"

"It doesn't look like it, but stay prepared, we've still got one more floor to go."

"Alright, well, good luck!"

Thomas rather quickly finished up with the check-in and closed the door, he still felt rather dirty since that encounter with the weird stuff on the roof. He didn't really notice his shoes had moved, and looked perfectly clean, or that an odd, white, almost milky substance was on the floor just inches from his feet. He simply stepped past it, and walked towards the bathroom. He needed a good shower.

Thomas moved into the bathroom, leaving the door to his bathroom ajar. Out in the hallway, a certain rolling fluid seemed to be creeping in Thomas' direction.

He started to strip his work clothes off and hang them up. Grumbling with a bit of anger at the futility, even the brief excitement brought him.

Leaning over the rim of the bathtub shower combination he moved to turn on the water. The slight gurgling of the water readily moving up the seven flights of pipes to start steaming out of his shower head. Thomas lifted himself over the rim to step inside of the shower. Starting to wet himself down in the warm water that soothed him. Showers had a habit of washing away his problems for the briefest of times.


This being was avoiding it too well! It was aggravated, using it's frustrations to move after the life before him that was eluding himself so well. It could feel another sweet nector dropping down onto him, only so many planet had this liquid on it. It craved it much of the time. Feeling almost revitalized by the water's microbiological organisms. But it paled in comparison to the life here.

Though it gave It the power it needed now to scale the cold dead surface that separated It and It's prey. Moving up the cold surface, It felt It's prey reach for something next to him, and suddenly rest it down. Taking It's chanced, it moved to envelop the smooth wet block of what it could now determine as a cleaning agent.

These being bathed in this liquid!? Preposterous! Though it was clear now to It that that clearly did. Suddenly, it's prey had grasp It! Success, It could now feel the texture of the beings flesh against It. It had won! Though, how to assimilate with the being? It's surface was too tough to absorb from here... It'd have to find a new place.


Thomas reached for the soap. It felt odd in his hands, thicker and like it had been sitting under a warm stream of water for a lot longer than he had to lather it up. Almost as if it was sticking to his hands. He shrugged his shoulder, head leaning back while he brought the soap to his chest and started smear the soap to lather and clean himself off. He grunted in a bit of surprise, it felt much more... heavy on his chest. He pushed it away, just playing it off to the rather 'used' feeling of the soap. Lathering down his chest and trim stomach.

He was wide and bulky, but he barely tried to make sure his form was muscular or 'fit'. His stomach was slim and flat against his hands. Sighing he stepped against the downpour of water. Rubbing his hands over the lather. Grunting, it felt -sticky- that wasn't right at all! He stepped back and looked down over himself, and was met to his surprise, covered in a thick white film of off-white slime!

He suddenly felt a cooling sensation where the thin film covered his front and chest. He was dumb-founded and shocked, almost staggering back onto his ass. He paused, body almost locking up but completely relaxed. His muscles weren't tense. Though he felt like he didn't have control. The film started to almost 'wash' down his front while it practically slid down his stomach. He shivered, his back tensing as the slim seemed to press around his groin. His cheeks reddening with blush. He couldn't help this, his length, modest in size, no more than a few inches of soft flesh in it's current state was getting harder.

He could barely focus let alone stop this. The slime seemed to covering his groin, sliding down and moving to cover his raised balls. Shivering as he almost shrunk at the cold feeling of the slime. Enveloping him for reasons he couldn't comprehend in this state. He wanted desperately to move his hands, but he couldn't figure out how to. His body was frozen to his own will.

Instead he could clearly feel his length stiffen around the cool gel. A whine escaped his lips. The water still raining down on his toes. He could feel his feet, his skin still fully responsive, but the muscles just didn't move! Thomas watched helplessly as the slime worked his modest length up to a full erection, the tip being washed with the spray from the shower-head. He closed his eyes tight feeling the heavy goop climb up his cock. Gasping as it all seemed to form around the shaft. Even though it was shapeless, it still felt like he was being sucked at.

Thomas shuddered. His body started to move on it's own accord. His hand lurched to his length and squeezed around it hard, warming the goo underneath his palm. Panting heavily. Knees weakening. He slowly moved down to sit on the floor of his tub. His head falling back to moan loudly. His eyes widened. His groin tensing as the pit in his stomach fell. He could feel his seed being sucked out of him. Hidden by the obstructing goo, he couldn't see how much he was releasing, but it felt like loads. More than he knew he could let loose in one sitting, especially one as strange as this was.

Panting heavily. His length warmed by the goo, instead of feeling chilled by it. Looking over his still covered length, he tried to tear away the squishy substance. Groaning as each slightly movement sent a jolt of pleasure up his spine. Breath hitching in the back of his throat, he suddenly felt an intense pressure at the head of his cock.

"F-fuuuck.. .w-what's happening, this has gotta -stop-." He called out, hips jerking forward. A slight twinge of pain broke through the veil of unusual pleasure. His length felt heavy suddenly. The goo beneath his fingers suddenly felt thinner and thinner. Eyes drifting down to his groin. He gasped, the goo was going -somewhere-. He couldn't tell though. Suddenly feeling in-control, he lurched up to look over his cock. The goo wasn't slipping into the tub, but there was less and less of it by the second!

He gasped, his length jerking against his groin. Thomas was suddenly aware of what was happening. He cried out in horror as the slime slipped from underneath his fingers, all of it forming at the crown of his cock. His length looked so much thicker. Almost as much as a beer-can. That goo was sliding down into his cock! Thomas' fingers reached to try and grip at the slim and pull it from the head of his member, but the substance was so slick, his fingers couldn't get any purchase!

The man cried with a defeated groan as his length swelled and thickened that much more to allow the slime it's home. Gasping as he felt the control of his legs and body once away. Immediately he sat up, moving to turn the water off. Turning to slide from the tub, tumbling onto the smooth linoleum floor. He groaned as he landed on his front, ever-stiff cock filled with that goop pressed tight between him and the floor. The pressure on his cock eased as that goo seemed to go somewhere else!

Thomas pushed himself up onto his knees and looked down. Not a trace of anything on the floor or from his cock, but it was indeed thinner, no longer bloated with the goo. He groaned, an intense pressure in his bladder. He held his stomach, panting. An almost screaming down seemed to blast against the inside of his skull. Yelling only one thing. 'Squeeze your cock!'. Desperate for options, he assumed the voice was his instinct, and he immediately squeezed his hands down on his shaft.

The pressure seemed to move inward. And he gasped, hands locked, he was too confused, with fear mixed with pleasure to remove his hands, feeling the pressure move through his bladder. And then further down. Thomas gasping and in awe, the pressure reaching an end and abating, but his sac, almost deflated in his fear, started to balloon out suddenly. Groaning hard, he could feel the added weight to his balls. The sensation making his cock throb between his finger, lurching out rockets of unused seed to paint the floor. Even as he came, his sac only seemed to get plumper and plumper.

The sensations all suddenly past, Thomas fell onto his palms to marvel again, the most cum he'd ever manage to shoot in a single load messing the smooth floor of his bathroom. Panting heavily, wet from the shower and sweat of fear. Choking on nothing for a time before he could fully acclimate to his situation. He stood up with shaky knees, running into his bedroom. Planting shaky arms against either side of a full-body mirror. Staring at himself- namely his sac, intently.

Part of him was mortified and confused. The other turned on by the impressive, and startlingly normal shape of the bloated sac. Usually, if he'd pumped, or if seen someone pump, they didn't quite keep the same shape. Now they were perfectly normal, but large looking. Hanging nicely against his thighs. "W-what, what in the hell just -happened-."

A voice chimed into his thoughts. 'I'm joining you... Thomas. I need you to lie down, and relax.'

Thomas nearly fainted, the voice wasn't his own, it hardly sounded like a voice! More like... a feeling. Staggering backwards from the mirror looking mortified at himself, he slowly trudged backwards. The back of his knees meeting the side of his bed and he slipped back onto the bouncy surface. Gasping as he was melt with a wash of relief. "T-that's not right, I shouldn't feel this good."

'You'd be right Thomas, we are making you feel complacent, you have the right mix of chemicals, other species I've encountered, would call this relief... if your thoughts, I see this feeling as 'afterglow' from an intense sexual experience. While, our meeting not directly sexual, I see the space I have chosen as my home within you will make our experiences together largely... sexual. I only ask that you accept, so I can form the bond required to completely my transition into... the "man you wish to be". At least, that is the best way I can position this to you currently. If you refuse, I promise to leave, and make the sensations more pleasurable to you in thanks, for providing me at least the knowledge I require to continue my time here on "Earth".'

Thomas was overwhelmed, but incredibly calmed by... something soothing tone. "You're not... from Earth?" Was the only thing he could manage to say, even underneath the mountains of questions he felt needed to be asked. His sac gurgled, and Thomas arched, groaning. Gasping as he felt the weight increase between his thighs. "W-what are you doing?"

'Thomas, I do not come from this planet, no. In your terms, I am a... parasite. Unable to exist on my own, I use other organic species to sustain myself and reproduce. I am... very old, from the knowledge you hold, I am older than your civilization. From your comprehension of 'Time' I believe I could be billions of years old. Perhaps, even one of the first beings of sentient life known to the 'Milky way' as you Humans have named this formations of stars. I am currently... reproducing. This part of your body houses all of the organic material I require to be more. I seem to be getting larger in the process. For I am no longer a main part of myself, but a mere piece of a 'slime' you stepped in when traversing across the roof of this 'building'. Your way of language is very... raw and primitive. I am enjoying it."

Thomas listened, rather intently at that. His arms felt tired and at rest, he didn't want to move them. Unlike before, he was comfortable. And with this euphoria washing over him, he felt strangely at ease with this parasite invading. "What did you mean... making me the Man I wish to be?" He asked. Another gurgle, louder than before was the onset of of another feeling. One of pleasure Thomas wasn't quite to familiar with. Letting out a shuddered gasp. He couldn't help but pushed himself up, a hand moving to his groin. The other stretching back to keep himself up.

His sac was gurgling quietly now. The pleasure making Thomas' again-modest cock start at attention. The sudden rush of feeling as the skin around his sac stretched around his expanding balls. He bit his lip, feeling his cock almost... harden? Feeling the turgid length stiffen and grow more pronounced to match his now positively hefty sac. His knees spreading to let the orbs slip and weight between his thighs. Almost reaching the bed between his knees.

'I meant if you accept me, you will change. Though, I see there is much skepticism around race in your planet. Do the animals in your kind fight? No... you've dominated them. You're warring still between each other? This Earth is much less advanced than my last home. Though, I apologies Thomas, that is besides the point. You will no longer be... human. You will be... us? We would have no name. And I would use your mind to define what we shall become. For that image will spread across the world. With you... as... Please, I see again this isn't an honoring statement to your... culture. But you shall be a breeder... a queen of sorts. Starting, you shall produce more of myself, so I can in-turn, spread your image across the world. It may bring unity, as your species helps me forge across the stars.'

'From your knowledge I gather... there are billions of humans. The most of one race I've ever encountered upon a planet. You could be at the forefront of a new face for your humanity. My reasons for doing this, offering this, are purely for survival of my own kind. Time shall pass, and I will soon look for more hosts. But judging by my impression of your... I could make Humanity stretch across the Galaxies.'

Thomas had hardly been listening at that time. He heard breed, and being at the fore front of a new human civilization. He was more interest in his cock. It had... grown, before, a modest Five inches give or take, he was now standing proud at a good six. With a sac that looked like it could produce a load that would cover a mans chest in one-sitting. He let out the faintest of moans. Hand squeezing his cock. "H-how much would I change if I accepted you?" He asked, leaning back on the bed.

'Within the span of twenty-four Earth hours? Completely, as you change, by feeling what you want, I will provide, and you will change accordingly. I ask that we work with haste in-order to achieve a form that would help me reproduce the fastest. For I plan to spread and calm all within the next few... Earth revolutions around the sun... or Years, as you perceive them."

"On one condition will I accept you." Thomas spoke. "All must be able to enjoy the change. It will let people be more into changing. I intend to enjoy this..."

'Thomas, I would not ask this if I didn't intend for this to be mutually beneficial relationship. Or... symbiotic in your terms.'

"I accept you."
