Sister Futa Mares

---

Kink with Her Sister

Mira sighed, a towel wrapped around the mare's body, her lightly coloured fur coat gleaming faintly with good health - naturally a golden shade, like the coat of a palomino. Yet the mare was set apart with a chocolatey brown mane and tail. It was not typical of natural colouration and yet alluring, all the same, the kind of mane that one wanted to run their fingers through, all to see if it was as soft as it appeared.

"I've really got to get going..."

Yet she was slow to hasten into the bathroom of her family home, casting a longing glance back down the hallway behind her. She'd held off for a few years on going off to college, but the time had come, after working to help pay for it, and she was most certainly going to miss the world where she had grown up. Especially her sister, Karly, one of few anthros she'd ever met that could understand her and what she went through.

For the sisters, even though Karly was white coated with a startling, blue mane (that one she'd definitely gotten from their father's side of the family), were not quite as they appeared, even if Mira had made fewer efforts to hide her body over the years and what she was. Although they appeared, at first glance, to be normal, anthro equines, they were not wholly mares, even if they identified as females, what fit them most naturally. Naturally, however, they bragged a shaft and balls rather than a female slit between their legs, the breasts on their chests deceiving the eye.

It had been difficult for them, but Mira had been able to protect her sister more as they'd grown older, when the truth had come out, fiercely protective of her nineteen-year-old sister, even though she was only a few years older than her. Yet such difficulties would never be faced alone, Mira thought, as she stepped into the bathroom and turned on the shower for a rush of heat and searing water.

"Ahhh..."

The towel dropped around the mare's hooves as she stepped into the large shower cubicle, letting her bare body be revealed, though in the privacy of the bathroom that was not so much of a bad thing. As the water soaked her mane, slickening it down to her neck and darkening her coat of short hair, she moaned lightly, letting the worries of the day slip away.

Everything would be okay. And she would always be on the end of the phone line for Karly. It was not as if her college was all that far away, after all, and she would be around to visit plenty, even on the weekends. She was fortunate to have her own car, in that regard: one thing she had worked at saving up for before going away.

Little did she know that her shyer, quieter sister had been watching her, the white mare stepping into the hallway, right outside the bathroom door, with a flutter to her nostrils. Wearing only a pair of shorts and a crop top, she fiddled with herself, adjusting her clothing, though, if all went to plan, she would have it off and on the floor soon enough.

"Come on..."

She pushed herself to do it, natural lust and desire pushing her on while the fear of putting herself out there, especially to her sister, held her back. How was she, after all, supposed to know how her sister was to react? Karly dithered, shifting her weight from hoof to hoof, but her nervousness could not be put first when her lust swelled so fervently, shaft pushing up, swelling with desire.

She could be quiet and promiscuous - probably more of the latter as she grew up and into herself, though that remained to be seen. There was plenty of time for Karly to work out exactly who she was, but only so much time for her before Mira headed off to college. And who knew how long it was going to be before she saw her older sister? Biting her lip, Karly let out a soft moan. She had to try... Had to see if the connection was there, desire twisting and roiling in the pit of her stomach, her fingers tracing over the spot lightly as if there was a fire, literally, burning inside her.

She slipped inside, the steam clouding the shower cubicle, filling the air.

"Karly?" Mira called from inside the shower. "If you're using the toilet, be quick!"

Karly didn't answer, instead pulling her crop top off, her heart pounding, shorts following swiftly to leave her bare in her white fur. Droplets of moisture clung to the hair of her mane and she ignored Mira's startled cry as she swung open the shower door, a small smile on her lips, eyes smokier and sultrier than even Karly knew how to make them. Somehow, something like that just came naturally to her, which was nothing of a bad thing.

"Karly!" Mira laughed, shaking her head, though it was not unusual for her to see her younger sister in the nude, being comfortable with nudity as they were. "What are you doing? Can't you wait for me to be done? Wait..."

Her eyes dropped to Karly's shaft and her eyes widened, the younger mare before her pressing in close, letting her length rub against Mira's all too rapidly hardening one. Mira gasped, sucking in breath, but then Karly's lips were on hers, tongue invading her muzzle, capturing her in a kiss so passionate that it made her dizzy.

"Karly..." She breathed, sliding her paws down Karly's sides as they broke, panting, from the kiss. "What are you... Why now? Ohhh..."

Karly's paw grasped Mira's throbbing shaft, thickening up with pulse after pulse of blood, the mare nickering keenly.

"I wanted to give you a proper send-off," she breathed, emboldened to her lust by her sister's quick reaction. "But I didn't know how to thank you properly, to show you how much everything you've done means to me..."

Mira nickered, stroking her fingers down Karly's slenderer body, the younger mare's abdominal muscles showing, a little slimmer than Mira, who was curvier with wider hips and a larger chest. Whyever would she have turned down such a thing, though the "naughtiness" (hell, she hated that word!) of it sent a tingling prickle down her spine that could not be denied.

Nor did she want to...

"Oh, Karly, I would have done it all for you," she breathed, snorting softly, her shaft rubbing up against Karly's smaller one, which was about half the size of hers. "Mmmm... But you don't have to thank you..."

"There's no risk," Karly nickered, eyes half-lidded with desire. "We can do this... Mmm... You feel so good against me..."

Her aroused shaft thickened up further, stimulating Mira, though neither mare was by any means fully hard. It was a journey to get there, pre-cum spilling lightly from the tip of Karly's cock, the mares grunting, groaning, letting the natural roll and grind of their bodies press together, a rhythm that inherent breeding instinct understood.

Mira nipped at her lip, hiding a smirk, turning the water off only so that it would not wash away the pre-cum slickening hotly on her shaft, the tip wanting to flare, though it was thick enough already as it was. As it throbbed to full hardness, Mira ground against her, snorting hotly, leaning over her sister as if to dominate her. Paws on her older sister's chest, Karly nickered and groped, rubbing the mare's nipples, adoring her and her body, thrilled that she was finally able to get what she had been fantasising about for so long.

But, of course, it was Mira who led her from the bathroom, knowing that they had the house to themselves, their cocks hard and throbbing, balls aching with raw, unbridled need. Karly tugged her towards her bedroom, wanting to show her something.

The bedroom, in fact, was filled with numerous sex toys, all set up on the shelves of her bookcase (which was suspiciously devoid of books) and across the shelves, a dildo even dangling from the overhead light. Mira could not stop a bubble of laughter from bursting forth, clapping a paw over her mouth, even as Karly excitedly pointed her towards the chastity devices, suited for equine anthros, and other toys, including e-stim and butt plugs.

"Look! Bet you didn't know I had a collection like this!"

"Karly!" Mira laughed, shaking her head. "Oh, you wicked mare... Did you decorate all of it like this just for me?"

Although she blushed, Karly nodded, cocking a hip out with one paw on it, a smirk on her lips.

"Yeah, sis... I thought you might like it. Maybe then you'll come back to see me more readily."

Of course, Mira would be back more often than ever to make sure her little sister was okay, her cock throbbing, glistening with the pre-cum that Karly had dripped onto her in the bathroom. Almost lazily, Mira leaned back, letting her throbbing cock take full precedence with a lick of her lips, her paw sliding over her shaft, showing Karly, very obviously, how she smeared the pre-cum over her length. It clung to her fingers, spreading out between them, a slick trail left in the wake of her fingers as she used every drop that had been left there to lubricate her aching length.

"See something you like, Karly?" She groaned, ears splayed, presenting her shaft invitingly as her heavy balls hung beneath, churning and practically overproducing cum in her need. "Oh..."

Karly took over, her paw replacing Mira's, though she could not resist dropping to her knees, taking the head into her mouth and suckling faintly. It was crude and quick to take her own sister's cock into her mouth, suckling around the head, the thick flesh, the spongy fleshiness straining against her tongue. Against herself, Karly moaned, though the mare would not have changed anything about the moment, all for the lust that she wanted to lean into, more and more, with her sister.

The Filly Maker: Bound and Dominated by a Futa Mare

There are females in our world that are not true to kind, although they look to be as natural as any woman. One would have to look closely, or be fortunate enough to see them in the boudoir, to tell that they are not all female but know more of what makes a male a male than any female has a true right to know.

And why is that? Because they are both genders at the same time, always wanton and always seeking out new partners to lure back to their stables of pleasure.

The filly makers are out to take what those beneath them crave, two-legged mares with human intelligence and especially bred to be lustful and skilled in the raw art of love-making. But they are not what they seem, mere mares, packing extra equipment where it counts in the stables.

The only question now as to which filly will come by their special brand of treatment next...

But there's always more to take in as a new friend of Fyr's takes a liking to a stud of her dragon brother, keen to get something, well... A little something, to say the least. And Fyr can't resist taking her inclinations a little further, teasing and wanting, letting her friend get in closer and closer while she watches, her brother waiting to snap up his kinky piece when her guard drops.

Cuckolded? Well, his sister loves it...

The Unicorn Siblings: Satisfying His Pure Sister's First Season

Sapphire, a young, adult unicorn, is experiencing her first season and, oof - it's a doozy! The heat, the need... She's never before felt anything like it, to that extent, trying to cool her marehood in the river, if only to find some tiny modicum of relief.

But her brother is there, as pure as she is and desperate for something he cannot put a name to, Albion studly and everything a mare in need could possibly desire. She spreads her legs for him, bracing - and the rest is history as he pushes over her back, taking her for the very first time.

Nothing will ever be the same again...

Note: this story contains consensual intercourse between two non-anthro unicorns that are related to one another and are adult characters.
