The Stallion and The Mare
#1 of Realistic
It's been a long time since I've had any activity here, and this story isn't normally what I write, but I was thinking of doing something new with the time I had to write this one.
After an hour of searching for her, the black stallion found the as yet barren mare that had joined his fold but a month earlier in the search for a mate, but the stallion's history with the female was left unremembered and insignificant in his simple mind as he approached and would have been the final thing therein even if he bothered to keep track of each specific mare that travelled with him on the plains, for the fragrance of heat had gone straight to his heads, both the one above his shoulders and the one between his legs; and he soon took to sniffing her body to catch more of the intoxicating aroma.
From its sheath, his member unfurled swinging, and she did nothing to stop his advances as his head lowered to her hooves and back up to her midriff, an admission that also practically admitted she was in season and willing to carry out the mission which came with that season. She started an exchange of whickers that continued until the young mare watched her new mate intently as he continued to taking in her hindquarters when he first saw her winking vulva and felt his shaft bounce under him in anticipation for its caress.
The stallion's lips curled back, and he lifted his head into the air as he swung his neck away from the mare, making sure to huff the arid atmosphere of the grasslands that was marked by her estrus. Her musk drove his member wild, and he was soon watching her wink from behind as fluids seeped from her passage and it waited for him to embark. Then a nervous instinct hit her, and she lifted her tail slightly to urinate before the stallion. Without a thought to speak of, almost before the yellowish flow of this new fluid was over, he took to the glistening grass beneath her hips to lap it up.
As soon as that work was done, he lifted his head up to make his first contact the vagina, chewing the base of her tail and panting into her tightening walls as both mare and stallion anxiously awaited what came next. The signs of her estrus had driven him mad with lust through a mix of all possible types of sensation from the scent of her body to the sound of her sweet whicker and the sight her desperate winking, and it was time for him to mate her.
Taking another huff of the newly empowered musk the temptations nature placed before him and his anticipation for rutting his new mate became too much, and he could no longer passively observe the signs before him. Instinct took over the animal's mind and muscular hind legs lifted his frame, rearing up as his penis trembled and flooded with an extra burst of blood, making the final preparation for the ultimate part of nature's operation. Then the stallion stumbled forward on two legs and grunted hard as the mare whinnied while his chest met her hindquarters and his forelegs slipped past them to grip her hips to aid his motions forward.
For her part, the mare took a step back, sensing that the alleviation of her heat was coming and growing more and more ready for him to enter her; but the stallion would unfortunately take some time to find her entrance with his shaft after his hips shifted to aim at the slippery folds around it. His fetlocks danced beneath them as he made his attempts to finish mounting her. He bucked hard, but the dumb, desperate strikes of the taller, heavier animal only bent his erection around her plot and his sent his now slightly flaring head slipping around her vulva in and out, sometimes rubbing the tight puckering ring of flesh that was the mare's anus as he thrust blindly at it. The stallion had almost lost the volition to deliver the package he was sending while the mare began to shift under his weight and try to help, but fortune had it that they would mate now, for his head eventually nestled into her still-winking, still-oozing vulva as he took a step forward; and he was inside the mare to his medial ring within a second, stimulating the mare and making her lubricate his length even more.
In another second, he was in to his testicles and pumping into her body, head poking deeper and deeper as it continued to flair, growing in diameter awaiting his climax. The mare could feel his hot breath against her withers, and she shifted once more to accommodate his greater girth, even having to spread her legs further apart as he continued thrust back and forward while her vagina clenched tightly around the vigorous member within it.
Since the time he'd reared up to complete their coital dance, the stallion had been letting off precum, but whereas those drops outside the mare's vulva were now lost and useless, each new drop aided in his movement and helped to magnify the maddening pleasures that were now running through him unstoppably. He could feel that he was close, yet the feral lust of the animal could not let him slow down or stop to make it last longer. Nature demanded an immediate pay off to the stallion and the mare for following it like foals on their mothers' teats in the weeks immediately before weening, knowing somehow that the end of the line was near.
Finally, the stallion's flair reached its full size as it slammed into the mare's cervix with each slightly upward pounding of the animals rippling hip muscles, and as it caught, he snorted hot huffs of air over her neck and began biting down on the roots of her mane while any thought that might have occupied his mind was chased away at a full gallop or devoured by its apex predator: the lust the heating mare had instilled in him. His hind-hooves stopped stammering in the wet earth beneath them, and his tail began to flag as both lost their breath for a time. Her nethers suckled him welcomingly for their chance at his foal as he slammed harder into her cervix and her very womb. Both were climaxing.
He ceased thrusting for a few seconds as the first massive stampede flooded the crevices at the entrance of her uterus, mind clouding with the euphoric narcolepsy that always followed that first wave of seed when he plowed the fields and held his pulsating stallionhood still and extremely sensitive inside their mate. As the flood continued, the foals had nowhere to go except deeper inside their mother whose own orgasming body took them eagerly as it seemed to collapse around them and push them encouragingly deeper. Meanwhile, their father's thick, trembling head blocked their only way out of her warm, safe depths and failing to complete the task nature bestowed on them the moment they were released. When those few seconds were over and the first wave of pleasure had passed the stallion's mind, he pushed his hips hard into his mate and forced their foals to slip into the now gaping entrance to their mother's womb where one was destined to take its hold. She was left clenching her walls around him, feeling the new sensation of stallion seed within her body and shuddering as she felt utterly paralyzed by it.
The phase of their coitus following the stallion's ejaculation lasted about half as long as the episode preceding it. After about thirty seconds of slowing thrusts, the stallion left his forelegs to go limp in shear exhaustion on either side of the mare's barrel; and his erection, once something of some impressive stature and capable of driving his mates to whinnying gasps beneath him, shrank within her after it finished sewing all but the slowest foals in her field, and those lame stragglers accompanied him when he left with a splash on the already-wet dirt.
As soon as he'd dismounted her, all concern for the other specimen seemed to leave both animals' minds, and it took but one whiff of her well-mated rear for the stallion to tell that the work was done. She returned to grazing as she had been before the mating started and he went to recharge before searching for other mares in his harem to mate before they all fell too far out of season, but both were unaware that the stallion's foal, merely a cell now, was preparing to implant itself or of the processes they'd set in motion to cause it nor did they know that the stallion's lust, the mare's heat or the movement they'd taken part in were merely the means to nature's ends.
