Lisa shuddered, her body tingling with all sorts of sensations. Her gaze met with her brother’s, the horny fox growling sultrily at her with their cock grazing against her entrance, both foxes shuddering with lust, anticipation, desire for one another. The siblings had never thought such a thing would happen between the two, both lusting for one another from afar, from behind each other’s backs. Sephie always dreamed of this moment, getting to fuck their busty, sexy sister. Lisa always found her brother to be very attractive in so many ways.

And now here they both were, grinding into one another, Sephie’s tip grazing, prodding Lisa’s swollen, soaked entrance. “C-Come on!” Lisa moaned out for the male to stop teasing her. Her body was on fire, her heat was driving her crazy! She’d just sucked the fox boy off and drank a fat load, all that did was get her even hornier for a pounding. Now she was being teased, poked by that fat cock as if Sephie were waiting for something. Did they want her to beg? Plead for it? What more could they want?

“Beg~” That three letter word. That cursed word she hoped not to hear. The fox kept prodding her, never penetrating, only grinding. Their hold on her hips kept the female from thrusting herself forward onto him, too. She groaned audibly. Were they really about to do this to her? She’d just sucked and titfucked them and now they’re gonna tease her? What a jerk!

It was turning her on like crazy.

“Nnhff y-you’re the worst!” She moaned to him, her face flushed with embarrassment and arousal. She’d never begged to anyone before to get fucked. She was always a ‘take what I want’ kinda gal, always on top! Now here she was, pinned under this cute femboy, her own brother, and forced to beg for what she wanted. Her body couldn’t take any more of this teasing… she’d just have to swallow her pride and submit. “G-give it to me! C’mon, I need your cock in my pussy, I need it in my [i]womb![/i] I wanna feel those throbs, every twitch, every slam hitting my cervix, plunging through, pumping and breeding me to the brim!” She shuddered, trying her damnedest to at least grind herself against that girthy fox cock continuing to tease her slick and leaky entrance. Sephie smirked, watching their sister squirm and plead to be fucked out of her mind. There was no way they could deny her the dick she so desperately craved now.

“Hmm… if you insist~” The fox boy drove their hips forward, unceremoniously burying themselves balls deep into the steaming depths of their sister’s soaked snatch. Both of their backs arched, Lisa letting out an orgasmic cry as she immediately came on her brother while Sephie shuddered hard, feeling the intense ripples of their sister’s drenched cunt wrapping snugly around their fat cock. All but the knot filled that hot pussy, throbbing strong with the tip of the fox’s hard cock kissed against the heated fox girl’s loosened cervix. With just a few thrusts, Sephie would easily be able to penetrate deeper into their sister’s depths and let her really feel it.

Without skipping a beat, Sephie began to slam away into their sister, a slow starting pace that would ease out of her gripping canal before burying it all back to the hilt, listening to the fox girl’s pleasured gasps and loud cries of bliss. Lisa’s moans were music to the horny male’s ears, growling sultrily while they pummeled and bred. Every thrust sent them pressing and prodding Lisa’s cervix open more and more, threatening to enter her womb and really bury it good and deep. The female didn’t put up any resistance to her brother’s advances either, her body aching for it, needing to feel that fat, tapered girth enter her deepest depths and really fill her up. And that’s just what she’d get as Sephie’s next plunge into her cavern sent their dick even deeper as they’d successfully penetrate through into her heated womb.

“Fffuuck! Yes! G-get it in there [i]deep![/i]” Lisa cried in happy ecstasy, another gush of nectar splashing her brother’s dick in a second climax. Her walls rippled strongly, milking the tip of the male’s cock snug in her womb. She could feel the spurts of precum feeding her insides, eyes rolling up in euphoria as that alone felt like heaven to her. She could only imagine what the actual orgasm would feel like, the rush of rich, fertile fox cum feeding her depths, those virile sperms swimming deep into her core to assault her eggs, knocking her up in a heartbeat. Ohhh and she could imagine her brother still fucking her senseless long after that initial impregnation, rocking her world, rutting through her pregnant depths, taking sloppy seconds at the pussy they’d just finished creaming full of cubs.

“Kn-knock me up! I wanna feel it… I wanna feel you throbbing, cumming… [b]I wanna feel myself get pregnant![/b]” She cried out to the horny male rutting away inside her cunt, legs wrapping around the femboy’s waist to encourage them to fuck her deeper, harder, wilder! She shook beneath the fox’s roughness, listening to the gushing squelches of her drenched cunt getting ravaged, the squirting and splattering nectar all over both of their crotches with each hump, every thrust. The sounds really did make half the sex. “My pussy feels so good, doesn’t it? My womb’s so warm, so snug around your tip every time you bury that dick~ Bet you wanna cum in me so bad, don’tcha? Slam it all in, pop that knot in me and give our family a plus one~”

“Yeessss...ffuuck… Gods, yes~” Sephie growled deeply between gritted teeth. Her dirty talk was too hot for them, her constant going ons about feeding her fertile womb, getting her pregnant, breeding her senseless… fuck! It’s too good! “Grrhhh..so..damn good! Gonna flood your womb until your gut swells… knock you up and fuck you two times over! You want cubs so bad, sis? I’ll give you a full litter!” The fox boy howled, their knot throbbing angrily, pummeling and rutting, plunging their way into the heated depths of their wanton sister. Lisa’s eyes widened when she felt her tight cunt stretched open around that engorged, bulbous flesh, then rolling up in pure bliss as waves of pleasure overcame her body and an intense warmth began to fill her up deep in the core of her gut. She could feel it, the throbs, the pulses, the twitches… ohh Gods, the spurts! She could feel all of that hot, rich cum filling her up, so fresh, so virile, so pent up!

“Mmnhh [b]YES!![/b]” She screamed, back arched and mouth agape, drooling on herself as yet another orgasm violated her body and splashed down the male’s dick filling her to the brim with seemingly endless ribbons of spunk. Lisa’s tail grabbed hold of her brother’s, coiling around it and entwining their bodies in yet another way, connected hips, connected tails, and now connected lips as Sephie leaned down to meet her moaning mouth with their own. Tongues wrestled one another while the fox male kept grinding up against her, stirring that throbbing, cumming dick around in her clenched insides. Her womb was so fucking snug, so damn hot around their tip, the way her insides rippled and milked, it was like she was trying to empty Sephie’s balls entirely! But Sephie was still far from done. Even after painting her throat, coating her womb, knocking her up and sating her heat, neither of them were finished. They were still much too horny for each other and the strong stench of sex, musky male, and bitch in heat still permeated every breath they took.

Sephie tugged hard on their sister, practically ripping his fat knot free of that freshly abused pussy. Immediately after pulling away, they’d slam right back home and resume a wild rut, grabbing hold of their sister and flipping her around from laying on her back to on her front, pulling her plump ass up high and going to town on her juicy pussy doggystyle. Lisa’s moans only got louder as she was fucked silly all over again, the slosh of her cum filled, swollen gut adding to the many sounds of rough, wild sex. She could barely speak under the pleasure of such raw sex, her mind going blank, head empty, no thoughts but that of her near feral brother fucking her with such passionate vigor, such a burning desire to breed, impregnate, give her more kids, more, [i][b]more!![/b][/i]

“Harder… HARDER! [b]Fuck me up~![/b]” She squealed, cumming on Sephie’s cock again. She’d lost count of how many times she’d came and squirted at this point, numb to everything but sex and pleasure. She’d throw her ass back into the male’s thrusts as much as possible, wanting to feel every hump into her body penetrate through her tender womb over and over again. She ached for it, needed it, she wanted that cock to violate her deepest sanctuary nonstop. She wanted them buried in, throbbing and nutting in that snug baby chamber, but those thrusts were just too damn good to make them stop! Her plump ass jiggled and wobbled with each of Sephie’s thrusts inside her, cheeks glowing red from the constant plapping and spanking of hips to butt, her swollen cunt just as red from the euphoric abuse of such amazing sex.

She wasn’t sure she’d be able to think of anything but constantly having her brother’s kids just to get fucked pregnant over and over again. The life of a brood mother to her sexy femboy brother… her womb trembled at the thought.

“F-feed my pussy… breed it, fill it, fuck it! Knock me up more! G-give me twins! Triplets! I-I want it all!” Lisa pleaded, begged, bounced her ass, anything she could do to encourage Sephie to give her more dick, more cum, more womb loving! Tears rolled down her cheeks, the pleasure so good it almost stung. It shouldn’t be possible to feel this good yet here she was, broken into nothing more than a slave to this amazing cock, her darling brother’s rough love, the constant stabbing of dick through her cervix, and that fat knot pummeling and spanking her fat pussy lips! How were they able to hit every spot of hers just right like this? She was so broken on pleasure she could no longer feel herself constantly cumming on Sephie’s dick—every single instance of their sex and lovemaking felt like an orgasm. A nonstop climax coursing through her very blood flow, her veins throbbing with ecstasy. She was swimming in the clouds, flirting on the edge of nirvana and she never wanted it to end.

Sephie was in just as much a primal state. Their poor cock ached with euphoric happiness, every plunge into that squeezing, steamy cave aching of the most raw pleasures that they couldn’t take any longer. Both of their bodies had become so tenderized, so sensitive, they’d both likely continue to feel the tingling sting of sex long after they’d finally end. And they were coming very close to that instance as heavy throbs surged through Sephie’s dick once more. They’d plunge powerfully inside Lisa’s hot pussy, back into her cum flooded womb oozing that hot liquid out all over their crotches, drooling down Lisa’s inner thighs, dripping heavily onto the bed sheets below, mixing into the flow of pussy juice drenching and matting down the fur on their bottom halves.

“Lisaaa… GRRRHH!! LISAAAA!” Sephie roared out to their sister as their knot dug back inside her and the second rush of hot cum fed inside Lisa’s tunnels. Her eyes rolled up, drooling on the bed, tongue drooped out, shaking and moaning, squealing, milking that dick feeding her, rounding her belly out bigger and bigger with more creamy fox cum.

“S-SEPHIIIIE~! BREED ME, BIG BOY~!” She managed to scream out to the male knocking her up twice over, ensuring she’d be very swollen with cubs in due time. One last, explosive orgasm washed over her body as the two of them howled to each other, their bodies giving in to the overwhelming bliss that only two siblings could give one another. They would collapse into one another, panting and huffing, both barely conscious as the fox continued to dump the occasional spurt of cum inside their sister while keeping tied to her this time, letting that excessive orgasm slowly flow into Lisa’s depths and further assault her fertilized eggs. Sephie would pepper their sister with light kisses to her cheeks while snuggling up on her from behind, rolling themselves over to be laying on the sides together, spooning the busty fox girl and rubbing on her big, rounded belly as the two slowly succumbed to sleep. It was still the middle of the night after all.

“Haah...hope that… takes care of your heat problem..~” Sephie spoke between huffs and moans, nuzzling at their twin’s neck affectionately. Lisa let out a small giggle, wiggling her fat butt a bit and purring deeply with a devious smirk.

“Maybe… what if I’m still horny later~?” Now it was Sephie’s turn to smirk as they’d pat the well fucked girl’s belly and growl into her ear dominantly.

“Then I’ll give you a proper wake up call in the morning~”
