“Open it!”

Sitting before the fireplace in the home she shared with her partner, Richard, the chocolate-brown mare pushed the present towards the cross-legged man, even as she rocked up onto her knees. Richard frowned and shook his head, eyeing the innocuously wrapped, square box, which had a tag on it that he had not yet read. The warmth of the embers in the fireplace warmed his skin as he leaned back comfortably in just a pair of soft, grey pyjama bottoms, Sierra somewhat more erotically dressed in a black lingerie teddy that set off the hue of her coat.

Swallowing his desire, Richard wagged a shaky finger at her, trying to look at her eyes and not her breasts swelling through the sheer front of the fabric. It was more difficult than expected and he ran his trembling fingers back through his blonde hair, pale skin standing out in stark contrast to her dark, glorious equine coat.

“It’s Christmas Eve, you’re not supposed to be opening them yet, you know,” he tried to say, although his words came out with little true conviction.

Blowing her scarlet forelock out of her eyes, Sierra spread her paws apart and shrugged, eyes far too widely innocent to be genuine.

“This one isn’t for me... It’s for you. And that’s why you should open it – now!”

He knew that look in her eye and it meant he wasn’t getting away with sliding the gift back under the tree for the real opening of it on Christmas morning, as had always been tradition in his family. Tucking his finger under the flap of paper, carefully taped down onto the present, he ripped it open, the mare watching his every move with her ears rigidly pricked. Even his curiosity was roused and it was with more than a little shiver of excitement that he slid a small, glass bottle out of the packaging, an eyebrow raised.

Just what could it be? Not understanding immediately, he turned it over in his hands to read the label on the back. And what he found there made his heart leap into his throat, the reason behind Sierra’s stunning state of dress – or undress – suddenly blatantly obvious, everything tying together like the last thread of a masterly crafted tapestry.

“A...” He blinked, jaw slightly dropping in sheer shock alone. “A fertility potion? Really? Wherever did you find this?”

Sierra waved a paw, sitting back on her rump, shapely legs drawn up together, as a cheeky smile pulled at her lips.

“Oh, I have my ways... These things do exist and, you know, in our land...”

She tipped forward, a paw trailing up his thigh; Richard shivered, licking his lips.

“Anything is possible. It’s as likely to be real as it is not. And it’s always worth taking that chance, that leap, dear...”

Richard’s breath caught in his chest.

“It could help you...help us...”

He didn’t need to struggle through the sentence for his lover to understand what he was getting at and the mare’s lips crashed warmly into his as she drew him into her voluptuous bosom. The mare’s eyes sparkled as she drew him in close, a paw sliding down from between his shoulder blades to the small of his back, fingertips pressing in as if to massage the muscles on either side of his spine.

Moaning, Richard relaxed into her embrace, finally allowing his hands to wander around her body and cup each full breast in turn, grazing her nipples with the most fleeting of touches if only to tease his dominant mare as much as she teased him. It was due payback, after all. Shuddering beneath his hands, Sierra groaned and broke the kiss lustfully, nearly sitting on his lap as a string of saliva connecting their lips for a brief heartbeat of a moment.

“Put a foal in me, darling.”

Richard didn’t need to be told twice as he unstopped the vial and shook it lightly, letting the contents swirl around inside as Sierra pressed her lips into his neck, teasing his Adam’s apple with warm kisses. He held it out to her, a near delirious chuckle breaking his lips as giddy joy combined with lust came to a head, senses overwhelmed by the possibility, one that they had thought, as a human and equine couple, was long, long lost to them.

Dropping a tender kiss on her lips, he pressed the bottle into her paw and folded her fingers in around it with his own.

“Will you?”

She didn’t need to be asked twice and tipped back the vial, swallowing the contents in one go, throat working as she gulped it down rapidly. When she finished, she set it aside and he wordlessly pushed the stopper back in, nose scrunching up at the faintest scent of blueberries: how strange. Sierra looked between him and the bottle, an eyebrow uncertainly raised, concern showing through her usually coy and confident demeanour.

“I don’t feel any different.”

“I can change that.”

He pressed her back, letting his body move over hers, although the mare was too strong and solid before him for the man to even contemplate having the strength to pin her down. No – he knew his place and the mare would have him soon enough, but that didn’t mean he couldn’t appreciate the lingerie she’d put on just to fire up his lusts and the potion that couldn’t wait until Christmas morning, if only for the hope that it could help them.

And it was so, all as he’d expected and everything he loved to. Bearing him back against the sofa, Sierra chuckled warmly as her legs slipped either side of his hips, straddling the human who looked so much smaller against her and yet still matched her for height, even with her hooves. 

“Sweetheart... I’ve wanted to have you like this beneath me for a long, long time,” she rumbled softly, lifting her hips to skilfully wriggle his pyjama trousers down his legs even as she knelt over him. “Not just sex and not just fucking... Not even making love to my man. But having you inside me with the possibility of a little one oh so very soon!”

Richard gasped, cock springing up against her soft sex – well, clearly the teddy lingerie hadn’t stretched to any kind of panties! It was all he could do to contain himself and not moan out with raw, unadulterated lust as she teased his nipples with her lips, catching each in turn with a dominant, loving bite that sent shivers down his spine.

“Then why don’t you have me?” He eventually forced out, the heat of her sex making him want to thrust up into her right then and there – but that was for her to decide the when of, not him. “I’m right here...ready to be taken.” His eyes smouldered. “And I’ll only ever be taken by you.”

“Oh, I intend to.”

And then her fingers wrapped around his shaft, positioning him just so, the tip of his shaft nuzzling between her lips in as intimate an embrace as a lover’s first kiss. Richard barely had time to gasp before she sank down with a low nicker, claiming his shaft for her own as the full length stretched her open. Her warmth welcomed him and the man groaned, clenching his teeth as his hands squeezed her soft buttocks of their own accord, pressing down to the firm, shapely muscle beneath the layer of soft flesh.

The mare moaned lustfully, letting her head roll back and expose a throat that he’d never dare to do more than kiss and nibble with oh so much adoration. He tucked his face down into her shoulder and muffled his moans the best he could, hips rocking up to meet her with as much lust as he could manage, being as trapped as he was in place.

But Sierra was after something different that night, her control lingering in alternative directions. Rising up onto her knees so that he had just a little more freedom to move, she moaned and pressed her heavy breasts into his face, letting their warmth squeeze in around his cheeks so that his world became nothing but mare, her scent enveloping his senses in a haze of lust.

“We’re going to have a foal,” she murmured, eyes half-lidded with mare-ish desire. “Fuck me like you mean it, Rich, I know you want me...”

She gasped breathily and fluttered her eyelashes in that way that made his heart sing, every move of her own calculated to make herself absolutely irresistible to him. Richard groaned. Oh yes, Sierra knew exactly how to play him.

And he’d only give her just what she asked for, each and every time. Exhaling in a rush, the man gripped his mare’s hips and rocked up into her with as much force as he could manage, a grunt passing his lips. She shuddered against him, arms tight around his shoulders, but he didn’t stop there – couldn’t stop. Thrusting up into the equine, Richard groaned and huffed into her breasts, capturing a nipple with his lips through the fabric of the teddy to a chorus of lustful moans.

She rocked her hips with his thrusts, groaning and egging him on to fuck her harder, Richard’s feet finding purchase in the plush carpet and using that leverage to slam up into her. There was no pretence that she was not the one really in control, but the brutal thrusts made her quiver, yearning for more, and she pushed her breasts into his face, demanding exactly what she wanted from him as he swirled a tongue around each of her nipples in turn, lavishing attention on them that only he and he alone could deliver.

But, being a male, he could not resist creeping closer to his climax as the mare’s cunny twitched and squeezed around him, demonstrating such expert control that he wondered, not for the first time, if she was trying to trap his cock inside her. 

“Sierra...”

That was the only word he managed to get out before orgasm rushed upon him, swamping his senses before he even had the chance to react. Her pussy rippled around him at precisely the wrong moment and Richard climaxed with a strangled groan, suckling on her nipple as if his life depended on it. Although he could not produce as much as a stallion, he certainly gave it his best shot, balls tightening up between his thighs to deliver spurt after spurt of virile cum, seed searching out the egg within her that he knew would be there, waiting to be fertilised.

And that was all the mare needed to climax too, her man beneath her doing what he did best. Sierra squealed like a feral mare in season as she reached her peak, tail flagging and pussy drooling with her climax, juices soaking his thighs with far more fluid than his poor balls could have ever hoped to produce. But her rippling, clenching sex drew more weak spurts from him as his orgasm stretched out, stars dancing before his eyes, and Richard huffed into her breasts as he clung to her as if for some sense of stability in a storm.

All orgasms, however, had to end at some point. Relaxing into one another in the afterglow, Richard murmured sweet nothings into her neck, speaking to her of the life they would have with their foal and how wonderful everything would be once she was pregnant. And, chest heaving, Sierra believed him, a smile on her lips as she nipped his neck playfully, tired eyes alight with promise and, above all, hope.

As, truly, they could only hope that the potion was real.

The next morning, Sierra groaned as she rolled over in bed, something ungainly about her waking pushing her back to the realm of full consciousness a little quicker than she would have liked on Christmas morning. But things were not all as they had been and, as she ran her paws down from her strangely sore breasts, the rise of her belly demanded her attention.

That wasn’t right!

Squealing, she leapt out of bed and stood snorting and trembling before the full length mirror in the bedroom as Richard rubbed his eyes and sat up.

“Look!” She shrieked, running her paws down her bare front. “Look, honey, look!”

And it could not be denied. Her stomach swelled with child, the mare appearing as if she’d been made eight months pregnant overnight, yet it was no illness and the baby within her squirmed and kicked anxiously, eager to be out. Her breasts too were larger, fuller, the nipples begging attention as they enlarged for her foal’s hungry lips. But it was the curve of her heavily pregnant belly that drew the majority of their attention. And for good reason too, for it held the life they’d been craving to bear for years on end.

And it was finally happening.

Throwing her arms around her husband, Sierra let him cry tears of happiness into her mane as her own heart brimmed over with joy.

They were going to have a foal!
