Erep
The rain poured hard, though the miners knew little of the conditions a mile underground. In the hot, humid and dusty mine another explosion rocked the very earth around them, setting loose more particulates. The machines tasked with collecting the ore swooped in like vultures, scooping up material by the ton to be smelted into precious jewelry. As the rock reached the refinery by conveyor belt, it went through machine after machine, breaking it down into tiny bits. The supervisor stood in a control room overlooking the facility, all of a sudden a flashing red light lit up, accompanied by an urgent beeping.
"Oh, dammit", the large equine said before commanding one of the workers to check it out.
"Something's jammed in there, shut off the grinder so I can get it", a small mouse said through the radio.
A moment later he emerged with what seem like an egg-shaped rock in his hands. The small mouse could barely hold it's incredibly dense mass. It was thrown into a container destined for the land fill.
A creature, about 4 feet high stood over a dead seagull, it picked it up and let it slide down its throat to be digested, the flexible tissue barely noticing the avian. The creature was a raptor, unknown to science; it was far superior to other raptors in strength, speed, and versatility. Its one curse was a horrible genophage that destroyed its female population over millions of years. Surprisingly, it adapted to this, gaining an ability to mate with any animal of sufficient size to carry its eggs. The resulting eggs were nigh indestructible, and could lay dormant until conditions were right. For now, we'll name this raptor Erep.
Erep managed to stay hidden at the dump for months by digging dens in the nearby woods, only venturing out at night to feed on refuse and any animals he could find. He was only a child, about 9 months old; at a year old he'd be able to mate. For now he just had to survive. Although he was the only one of his kind, his instincts told him to maintain his territory and prospect the animals therein, calculating their yield and ease of capture. This included the nearby town, where he often hid in the shadows at public places like parks and schools. His species didn't even require the victim to be sexually mature as the mating process changed the womb's anatomy to that of a mature raptor.
It had been a year since he hatched on a pile of garbage and he was ready to repopulate. He crept in the shadows of night, being careful to not make a sound as he got into a position to ambush a farmer's horse. The horse bucked as the 6 foot tall frame slammed on top of her, his 3 foot long penis immediately engorged with hot blood, its pointed tip easily parting the mare's labia. Her height made it awkward to mount her, but he was designed to mate much larger prey, his sharp long claws dug into the hide while his member hilted into the horse vagina. His 2 inch girth spreading the horse, her sheer size kept him from holding her down so he could enjoy it so he just held on tight as he pumped her womb with a chemical that slowly transformed her womb into a raptor's, it started releasing egg after microscopic egg, each awaiting fertilization. When the change was complete Erep pumped jet after jet of hot seed into her womb, calling out in pleasure. When her womb was filled he plugged her cervix with a plug of gel to keep the eggs safe from other raptors and animals. His member receded into his body and he dismounted her, running off into the night.
A month later, the farmer noticed his mare was behaving strangely, almost like she was pregnant, he decided to put her in the stall to rest, she started bellowing as juices trickled out or her vagina, she laid down and started to squeeze egg after egg out of her, each about the size of an ostrich egg, but speckled brown and grey. The eggs plopped down onto the ground with as loud thud. The farmer came running to check on the horse to find she had laid a dozen eggs.
"What the hell...
Two years later and the population had exploded, numbering in the hundreds with amazing diversity. The townspeople had only caught glimpses of the raptors moving in squads across the land. Erep had since become the alpha male in a tribe of about 16 raptors, each varying in color, from solid black to a rainbow of colors, and ability. Each one performed a specific task; stronger ones took down large victims to be raped by multiple members, while faster ones performed alone and hunted small targets like deer, dogs, and anthros.
As the population grew, more anthros were caught, resulting in uncannily smart raptors, able to coordinate attacks on rivals and strategize the capture of victims. Erep had taken a liking to anthros, as they were easy to catch and provided excellent pleasure. He waited by a street were middle school students walked home. He waited until a female fox, about 12, walked in front of his hiding spot in the woods. He pounced, clamping down on her throat to keep her from alerting anyone and quickly dragging her far enough away to not be disturbed. He tore her clothes off to reveal his prize, an untouched labia waiting to receive him. His cock extended to full size, pinning her, he thrust into her, making her squeal in pain, tears streaming in her eyes from both pain and fear. He shoved as much in as possible before pulling out till the tip, then slamming in again building speed, tongue hanging out the side of his mouth from bliss. His special chemicals poured into her small womb, making her feel a warm tingling sensation accompany the excruciating pain, it didn't take long for her uterus to change. He bellowed in pleasure as he nearly hilted himself inside her, pumping cum into her by the quart, filling her uterus and spilling out onto the ground. The girl cried uncontrollably as he filled her. When he stopped pumping seed, she felt a mass move up his penis and lodge itself into her cervix, sealing in the cocktail of fluids inside her. His ember retreated into him and he let her go, running off into the night. The girl walked home, naked and bloated with cum.
The next morning the bloating was gone, the cum and chemicals absorbed by her uterus, she didn't bother to tell her parents because of her embarrassment. She went to school sore and aching, with teeth marks on her neck. When she got home she felt a squeezing force in her abdomen, she went to the bathroom and sat on the toilet, she cried as searing pain coursed through. Finally, a single egg plopped in the bowl, the weight cracking the porcelain. She took the egg and put it in her closet, afraid of what it meant.
