#3 of Spreading Transformation (ARCHIVED)

I am breaking my spreading transformation series up a bit, to make them it a bit more easy to read and to get it out faster to you folks.


Sarah and James were sprinting through the school. Their bodies moving with a speed they could never have dreamed of as humans. Sarah's gait easily matched the giant horse running next to her and she was a lot quieter too. James's massive black hooves clattered and crashed against the flooring, the sound of his hooves reverberating through the hallways as the hard surfaces and metal lockers reflected and amplified the sound.

Getting out the boys bathroom was no easy feat, for only a few moments both Sarah and James had a gap in their constant orgasming and hormone fueled love making. They took the opportunity to escape the now thoroughly trashed, cum coated boys room. They were finally leaving behind its harsh flickering light and dusty cum-splattered surfaces.

Sarah was quickly defining herself as the brains of the operation. James's mind was too easily overwhelmed by his instincts and throbbing desire for pleasure. He came down out of it fairly quickly but his last tantric sex session left him no more than a sex-crazed animal seeking pleasure any way it could. Sarah had a deep empathy for James, as she had the same strong desires flowing and throbbing in her mind, its undercurrents were undeniable. The difference was that she had consciously embraced it. She wanted it and in turn it somehow gave way with her intellect when she really needed it to, keeping her at least partly in control.

Escaping the boys room was her idea, the caked and dried cum that coated the walls, ceiling and floor also coated them both. It wasn't rocket science to go to the showers, they were private and they would wash their cum soaked fur clean. The showers had the added benefit of being next to her gym locker. She knew she had an extra set of athletic clothes there for her lacrosse games. Nothing there would fit her now, her bosom alone would turn her thin lacrosse jersey into a tube-top, but maybe...maybe she could get back to normal somehow. She didn't have time to think about that right now, even her mostly functioning brain couldn't think too far into the future, keeping her overwhelming libido in check was anchoring her in the present.

As they ran their respective organs and flopped and jiggled with every bound and successive impact. Sarah's breasts were extremely firm and perky but still swayed uncontrollably as she ran, their contents jostling as the massive mammaries slapped together, small drops of milk forming on her nipple tips. James had no issues with his hard-packed muscled chest, his package was another story. As he ran his balls slapped and jiggled even more wildly than Sarah's breasts, their pendulous weight straining his impossibly heavy sack as he ran. James hadn't realized how heavy he was down there until now. It felt like somebody had tied cinderblocks onto his sheathed penis and added a couple more onto his scrotum for good measure. But still he ran, Sarah's behest was all it took to get him moving, he would follow her anywhere.

Neither one of them had a concept of how long they had been in that bathroom but the school's hallway lights were shut off, leaving only the secondary lighting to guide the way. The shadows of trophy cases and classroom doors blurred by. What few windows they passed only returned their own racing reflections, the sun having set an indeterminate amount of time ago.

Finally reaching their destination, their eyes were suddenly hit with a burst of light as they entered the large gymnasium. Unlike the rest of the school, its lights were still blazing. The showers were at the far end along with the locker rooms, they continued their run towards them, Sarah leading the way. Their feet loudly hammered against the wooden flooring as they resumed their sprint. If Sarah and James hadn't been in such a rush they may have seen the spread of three yoga matts organized in the center of the large gym floor.

They both slowed as they reached the entrance to the two locker rooms, Sarah's jiggling breasts and James's balls and sheath finally coming to a rest. Their legs ached, even though they had enormous strength and stamina, this was the first time they had run with them.

As they breathed hard, catching their respective breath, they heard faint sounds coming from both boys and girls locker rooms. The locker rooms dual entrances directly adjacent to one another. Their sensitive ears swiveled as they strained to make sense of the sounds, the maze of walls within making it difficult.

While his ears pieced together the sounds James sniffed the air with his broad and deep nose. He smelled...he smelled....everybody. Everybody that had entered that those locker rooms that day and possibly that week. It smelled like hundreds of teenagers, their sweat, dander and hormones coating almost every surface inside. He turned his head to the left smelling females, to the right, males. He snorted more loudly than he intended to as the smells began to overwhelm him.

Sarah was assaulted by the same strong olfactory sensations. Scrunching her nose as it flared open and closed, inhaling the detailed and mysterious aromas. The entrances to the locker rooms became portals to a world of sensation. Although Sarah's nose wasn't as large as James's it was still extremely sensitive. Without James noticing she entered the boys locker room as her crotch began to wetten. The smell of something strong was drawing her inside.

James remained at the entrance to the two locker rooms as the voluptuous rabbit disappeared inside. The smells having taken on another, new, stronger aroma, occupying him too deeply to notice her departure. He breathed more deeply through his sensitive nasal cavity. He smelled sex, traces of horny males and females both, their pheromones still wafted in the air and coating the locker room's surfaces. He breathed in deeply again as the scents reasserting themselves. He was starting to get a mental picture, it was like seeing with smell. His brain started to comb through them as easily as looking through a picture book. Each individual had their own unique scent and he smelled them all! There were three that kept coming to the forefront, surfacing above the noise and making themselves known, their pungent sweet aromas were intoxicating.

As James sniffed and snorted his nose, the pure volume of sexually viable teenagers that had passed through these doors made his male-hood throb. It didn't take much, his already sensitive balls and sheath were extremely sensitive from their run to the locker room. He hadn't realized it at the time, but the insides of his thighs were causing great deal of friction on his nuts as they ground and slapped their way against his hammering rock-hard leg muscles on the run. This only exacerbating the situation as his heavy scrotum was already so erogenous.

James tried in vain to keep it together. He desperately wanted to take that shower Sarah had promised him. Patches of cum had clumped his fur, causing it to pull uncomfortably as he shifted and moved. Dried pre and Sarah's lubricants matted down what wasn't covered in his congealed seed. It better revealed his massive frame but was also massively uncomfortable.

Since they had begun racing to their goal James had still been fighting this thing he had become, still fighting the heat rising from deep in his belly. He wouldn't accept it, couldn't. Despite that and all his best efforts his brain began to imagine all the vaginas associated with each distinct female smell. Their perky clits peeking above increasingly massive mounds of woman flesh. He began to imagine them dripping wet, their folds opening just for him, beckoning him to join with them. He would fill them, he would feel their immense throbbing tightness as he would fill them with his seed. He would sire many, many foals.

James's mouth began leaking a small stream of drool as his crotch began throbbing harder. "NO!" he suddenly screamed in his mind, breaking up the harem of throbbing wet pussies his brain had concocted. He had to fight it! He shook his head as he tried to clear his thoughts. Where was Sarah?!?! He needed her help, he needed her to help him calm down. He was panicking, his eyes darting around the cavernous empty gym.

As he panickedly looked around the gym his huge hands covered his crotch as best they could trying to ebb his growing heat. He could only get them over his growing sheath, his huge black balls were beyond his ability to cover. Hot flesh was beginning to push out of him and he didn't want it to happen. He was as in control, him! His crotch throbbing as he repeated this over to himself in his mind, his grip tightened. He crossed his thighs over his hands for added support. He remembered Sarah doing the same not too long ago, the thick lubrication leaking out of her luscious deep mound... Gahh! NO! He had to concentrate he could beat it this time, Sarah was strong, he would be too.

"Eeeeeerrrghrhhhhhhghh" gurgled out of his mouth as his hips began thrusting back and forth. His body betraying him as it pushed its temporarily stunted growth hard into his hands. His thighs clenched hard in rebuttal, reinforcing his hands position. To any onlooker it would appear as if the giant horse had to pee, really, really badly. His legs continued to cross as his hands pushed against the throbbing heat below. Hot slick liquid began to find its way through his tightly clenched fingers as he felt his heart push a massive amount of blood to his crotch. His body wasn't going to give up so easily.

"I can... I cannnn.... control.... Ahhhhnnnmnn" he managed to gasp as he ground his wide flat teeth. His massive jaw clenched as another massive spurt of pre found its way through his fingers. His balls ached and throbbed.

"Uuuuuughhhhh.....won't let it, won't let it win....hauuuughhh oh god.... I won't...I..I.." he moaned out of his now tightly clenched teeth. He pressed even harder against himself with his hands and thighs. Head craning downward, he fought the lust inside and out. His hips' thrusts sped up in return. His body was throwing its full weight against his hands and crossing legs now, his whole torso rocking like a sex-powered metronome.

"I won't....give...in. I can't ....*snort*.....give..innnnnaaayyyyhhhhhhhh!!!'" he bellowed as his voice transitioned into an long animalistic neigh. James was unable to rein himself in, his tenuous grasp on his faculties slipping through his pre coated fingers.

"Huuuuuguhhhhhh...I.....I....want....Sarah...Sarahhhh....I want to... to.. to.. .fuuuuuuuuckkkkkkkk" he screamed as he threw his head back. His protests became a mere whisper as images of rutting with thick pussies filling his head once more. His heavy cock penetrating each one in turn, it's broad, flat head thrusting greedily and deeply between thick labia as he deposited rope after rope of his seed.

While James's mind was once again lost in crazed animal lust, his hands were starting to travel. However, they did so without the assistance of his bulging furry arms as they were given a ride courtesy of his throbbing and rapidly extending column of meat. Inch after inch it grew below his thick digits. His cock pushing his now masturbating hands further and further away from his torso with each beat of his heart and throb of his swollen balls.

Thick hands kneaded and massaged his massive pink throbbing cock head. In their fury his hands did something unexpected, unintentional. His massive frame shuddered as one of his thickly nailed fingers pierced the opening into his wide convulsing urethra. His cumslit responded by pushing out a massive glob of pre around his finger like it was barely there. He thrust his hips harder as the finger slowly inched down into his slick pulsing wetness. He could feel his cock massaging and throbbing at his digit's broad rough surface. The feeling of being penetrated sent electricity into his balls and spine. James couldn't hold it in anymore as the images of him penetrating so many sopping wet pussies intensified, they smelt so real, so close.

Unbeknownst to James in his rutting, convulsing state, at least two of those pussies were not just in his mind.
