Seducing His Slut Sister

---

Her Brother's Temptation

She didn't take much seduction, the mare on her knees before him as the stallion grunted thickly in the back of his throat, powering over her. The thick rod of Jonas' meat slapped her muzzle crudely and it was all his sister could do to not suckle the fat length into her muzzle right then and there, the head flat and begging her attention. Alanna whimpered, her season rampant, tearing through her body with such heat that it was all she could do to stay where she was. Hidden around the back of the barn at the tail end of the day, twilight wrapping around them, she licked her lips and moaned, warm breath washing over the stallion's cock as he twitched and nickered.

"Is there something you want here, sis?"

Alanna groaned. Oh, he knew, he knew so badly how much she wanted it. It was impossible for her big brother to not smell that she was in season, her marehood winking and pulsing, drooling with her own arousal. She hadn't even been filled yet as she spread her legs, panty-less and her skirt flowing down her thighs, though cutting across high enough so that access was, most certainly, not limited in the slightest.

"Mmm... Yes," she managed to force out, though it took grinding her words past the lump in her throat to do it. "Yes... Oh... Do it, come on... You know how much I need it!"

Jonas only had a smirk for her, the bay stallion, who looked so much like her, snorting heavily. His nostrils fluttered, taking in too much of her scent, but it was easy enough to say that the young stud was far more in control of himself in that moment than she was. Clad in chocolate-brown hair like him, they both boasted a spill of black hair down their necks, tails thick and communicative at all times. Even then, hers had flagged, showing off her need without any reason for words to be used. The fall of hair was lifted well out of the way, pushing up her skirt, exposing her bare folds to the open air as she nickered bobbed her head, keen and yet frustrated at the same time. Oh, her brother did know how to tease her.

"A slut like you can give it a kiss first... Show me how much you want my fucking dick in you, sis, go on..."

He knew that he was going to get what he wanted either way but the lust was there to be satisfied and there was no ignoring it, regardless of what else was happening, the tenacious need of the moment. They could have been happened upon at any moment, around the back of the barn, but he wanted nothing more than to see his sister's sweet cunt spreading open around his cock, stretching and straining to take his colossal member.

Alanna huffed and whimpered but there was nothing she could really do about it if she wanted her bro to fuck her again, to get that fat length of horse-meat back where it belonged. Her lips had parted almost before her mind had even caught up with what her body was doing, driven to such highs without thinking about it. His shaft was bare and she still slurped lustfully, lewdly, down the length, saliva slopping around his tip as she drew him tenderly into her mouth. Her tongue pressed into the soft slit right at the tip as he moaned and she knew that she had him a little more, the barn offering them some protection from prying eyes.

Yes... Yes, that was enough. Her thoughts fell hazy, the world around her soft with concealment. They would not be found, no one would see, no one was looking for them. They were out there all alone and all she had to do was take his cock deeper and deeper, pushing into the back of her throat and deeper still. It may not have been especially comfortable for her but she didn't have a gag reflex, allowing him deeper. Her tongue pressed up to the underside, trembling in raw delight as he shuddered bodily above her, her skin prickling with heat that the cool evening air did not lend her.

"Yes..." Jonas grunted, lips twitching, the nerves there conveying the depths of his desire where his words would not. "That's more fucking like it, sis... You're such a slut for my cock. Why, you should wake me up every morning sucking my dick."

That was a good thought, a very good thought, but he had to take control too, roughly twisting his fingers into the slut's hair as he yanked her up and down his breeding spire by her mane. She whimpered around him but suckled all the more fervently, loving the coarse treatment, though, to be fair, Jonas would not have done that to her if he had not known how wet it made her. Consent was at play, as much as he reduced her to the form of a hot and horny slut that only needed to fuck and be fucked, and her muffled moans around his thick length told him all that he needed to know.

Down, more and more, her lips slid back and forth over the medial ring, how it bumped her lips and tugged at them, betraying just how much of his cock she had swallowed. Alanna's eyes watered as she strained to keep her teeth away from his sensitive flesh, though her mouth was sincerely only a hole to be filled right then and there. Even the hot spill of his pre-cum, so much thicker than the other guys, not stallions, that she'd been with, was lewd and lurid, drawing her further and further into the moment.

Her brother snorted and swore above her but Jonas wasn't that close yet, not quite yet. She had more of him to tease, her paws trembling up to his balls. Some guys were funny about their nuts being touched but not her big bro: he loved it. He grunted and swayed his hips while she massaged them lightly, always careful about how far she pushed things, for the line of pleasure and pain when it came to such a tender part of his body was deviously thin. It was a matter of trust though as he fucked her mouth like a glory hole, slamming in roughly even as her lips grew sore and her heart soared to be trusted to be treated in such a crude manner.

"Fucking slut," he grunted, the words pouring over her. "Only good for sucking cock... If you don't suck my cock tomorrow morning, sis, I'm going to come right in your bedroom and slam it up your arse... That'll teach you..."

She would have liked that. She would have liked that very much. Alanna shuddered. Maybe she would "forget" to wake him up with his dick wet in her mouth the next morning, just to be treated like that.

The stallion snorted heavily, leaning over her, drawing her in closer, his cock shoving itself deep with short, sharp strokes, loathe to pull back any further than he had to. No, Jonas wanted his cock deep, secluded away in her tight throat, her muzzle so sweet that it was an addiction that he simply could not get enough of. He tipped over her, hunching down, throwing his strength into his thrusts, hamstrings begging for mercy even as his quads and glutes tensed anymore. For his body was getting him there regardless of the ache, putting himself in a position that had to be held as the pleasure mounted and mounted, all derived from her hot, wet mouth.

End preview.

Lusting for His Sister's Feet

Oh, Jason knows that it's wrong to want for her so terribly but he does it anyway, unable to restrain himself from his lewd and crude desires. There's little that could hold a man like him back but himself as he peers at her through a crack in the bedroom door, drooling over just how her feet flex and bend, wanting to tickle his tongue along them in a sensual lap.

A massage maybe... Some personal attention? Anything goes as his lusts grow, a voyeuristic thrill taken in watching from afar but, sometimes, not all that far away at all.

Lust, after all, is better spent than stored...
