Your breath is hot on his ear, his buns hotdogging your enormous stallionhood. Your right hand is set on your hip, while you rest your other on the damp tile wall to your left. Steam from the warm water rises around your; the scent of a dominant, virile stallion suffusing the air with the moisture, as thick as the tension.
Huffing in the fog of your masculine aroma, you feel drunk on your own heady virility. Powerful. The mighty flexing of equine muscles across your body; the swish of your tail against your legs, the feeling of your thick mane plastered across your muscular neck and the broadness of your upper back; even the solidity of your hooves. And of course the weight between your legs and the thickness of your iron rod as you slowly grind into your room-mate, making you huff softly into his damp hair.
It's so fucking good! And now, you've decided it's time to share this gift with Sean as well, and bring him fully into the furry club. To make him a hot animal babe to complement your stallionhood, and indulge in this primal lust for life together. But you want this to be the best it can be for him, so you ask:
"What's your favourite animal?"
"Uh?" For a second Sean cannot process your words; his mind so muddled by your carnal closeness, the smokey tang of your voice and the press of your hard cock on his back -- by his need for you; by the rapid change in his feelings and your relationship. By your thick, enhanced pheromones stirring the human's blood and clouding his mind.
"The, uh, th-the fox," he finally manages to stammer. "B-b-but--?"
"Good," you croon. Yeah! this should be really good. You shift your hips in anticipation, drawing your massive cock along his back and between his asscheeks. A real vixen for me to fuck! You can hardly contain your excitement as you continue to whisper huskily in his ear.
"I'm so glad you love foxes... Because Sean, you are a fox woman. It's what you really want; what you really are deep down. And now, your love for me, the hot scent of my stallionhood, and your need to fuck me unashamed, is making that desire manifest. You ARE a beautiful, luscious, horny fox woman. A real vixen, and proud of it."
You feel Sean tremble against you. Since your words are true as you speak them, he -- or rather, she -- is thrilled, happy beyond words to finally become her true self. Her mind becomes clear as she embraces your words; everything clicking into place for her. She was confused by her feelings because she thought she was a man; now she knows she's a woman. Not just a woman -- a hot fox woman. It's natural for her to be horny, to be aroused at the sight of a big hunky stallion.
"Ohhhh...!"
The mental realignment swiftly flows out into her body in a wave of sexual heat. Sam groans as her clarity is submerged in the euphora of her brilliant pelage sprouting and erasing her humanity; her masculine flesh melting into a truly foxy lady.
You stare greedily as Sean's arms thin and her shoulders pull in; her waist tighten and hips flare out into a womanly hourglass; her back gain feminine definition as red-orange fur covers it. Her human hair also grows out, dark brown becoming a fiery red cascade spilling down her furry back. Your lust surges as her voice cracks into a sultry feminine moan.
"...Fu-uck!" The bliss is so overwhelming that she has to lean forward and brace herself with both hands on the wall. The water rains down, wetting her hair and fur as she feels her naked butt push into and inflate against your cock, and her chest grow heavy with her breasts ballooning with fat and milk glands.
She begins to grind that ass back against you even as it grows. Her former male shyness is forgotten; her identity as a horny vixen growing ever stronger as more mass flows into her chest, ass and thighs. Making her supple and deliciously curvy even as muscle subtly forms, giving her a tight sexy core, vulpine agility and the strength to carry her new assets. Her massive, round F-cups; which you can see overflowing her athletic chest, making her pant and gasp as they lewdly jiggle and tug at her while she works her hips -- as she feels her swollen ass engulfing your hard thick cock.
You yourself are so overwhelmed for the moment that you can only toss your head with a snorted "Fuck!" and grind back. From above her ass her brush -- big and luxuriant, brilliant orange tipped with bright white -- fluffs up against your chest and teases against your muzzle before curling aside, growing heavy with water. More white fur covers her front, adding satiny softness to her boobs and her smooth, sexy stomach.
Her legs also get longer, pushing her butt higher against your mottled rod: Sexy thighs leading into strong calves melding into foxy black-furred hocks and paws. Black velvet gloves form on her forearms, together with pads and claws on her hands. And -- unseen by either of you, but very much felt by her -- her sex sucks inward, her ballsack splitting open into a thick-lipped slit that drips pungent vixen honey into the potpourri of the bathtub, her cock compressing into a throbbing little pleasure button.
"Oh ye-ess!"
She tilts her head up, crying out as a small orgasm ripples through her, signaling the end of her transformation into her true form. She straightens, still unconsciously grinding against you, breathing deeply as she recollects herself.
"Oh my God, Darryl, that was... oh my God, they're so heavy..." She puts her hands to her breasts, feeling the water splash against her nipples. "...Sensitive...! Oh God Darryl is that your... against my... ohhhhh!" She presses her ass harder into your crotch as she becomes aware again of what that hot hardness she's been feeling is, and how fat and firm her new ass is.
"Oh God!" you grunt in response. "Oh yeeaahh..."
You grab at her hips, marveling as your fingers sink into the softness of her fur-clad flesh. She moans and leans her weight back into you, still shifting her hips as she gropes her luscious melons -- gasping as her fingers brush her stiff nipples as your look hungrily over her shoulder. As water falls across her front and mingles with the juices running from her pussy, her hot vixen scent emerges fully, making you flare your nostrils to suck in as much of the natural perfume as you can.
"Oh-ohhh, Darryl...!" she moans. "Why is it so good, ahhh -- I have... my tits...! unh my nipples! And God Darryl your cock...! so big and hard and hot against my... my... ass! Mmmmnnnnph!"
She leans forward again a bit and turns her head to look back at you, her eyes half-lidded, framed by long lashes; the formerly brown irises now liquid gold, her elliptic pupils wide with desire. Her long, narrow muzzle is boldly marked with black, the black pad of her nose quivers as your heady musk pours into her together with her own sweet scent. Her lips are parted with desire; her upper one more animalistic, her lower one fuller and more human; the tips of her pearly fangs just visible.
"Wow," you gasp, smitten. "You're... you're beautiful... babe."
The word feels right. Sean isn't a plain guy any more; she is a furry sex goddess and your pride rages with your boner, because you made her this way. And her pointed teeth flash in a smile both beatific and deeply sexual.
"'Babe'... ohhh yess..." She rocks her hips, running your hard, hot dick through her plump asscheeks, then standing to press her whole body back against your muscular chest. "I'm your foxy babe... This... this feels... so right. Mmmm..." She squeezes her breasts, still awed by their size, but rightfully proud. Feeling so hot, so beautiful, so sexy. So lucky to have a hot hunky stallion like you.
She lifts her arms for a moment, folding her hands behind her head, thrusting her bust into the water and inviting you to feel her up -- which you gladly do, running your hands up and down her sides. "Ohhh you're so strong, Darryl... make me feel so... good!" She looks back at you again, putting her hands back on her breasts as you settle yours back on her hips.
"Not sure how you did it, big boy, but thanks for... ohh... bringing out the vixen in me."
"Glad you like it, babe," you rumble, and give her ass a squeeze. She yips deliciously and her butt clenches around your cock. God her ass is so... fat! So... thick and firm, yet soft. Your stallion meat is sinking so deeply between her cheeks now, it's driving you crazy.
"Nnnngh... Oh girl...! Your tight bod and hot scent -- I can't hold back much longer!" You bend forward over her, sliding your massive pillar along her back, squeezing out a copious amount of pre onto her. It's hard to think, but you manage a husky whisper. "Want me to put it in?"
"Yes," she whispers back breathlessly. "Oh yes, Darryl... I feel... so weird down there; so wet... so empty... I need that big horse dick. Oh God, I need it so bad -- I need you."
You chuckle at her sluttiness as you loins clench. Reluctantly moving back a bit, you take a hand from her soft flank to line up your ponderous tool with her tight, virginal opening. As your head meets her lips she gasps again and wriggles her hips.
"Oh God Darryl -- I feel you on my... my pussy!" She trembles and bends forward, instinctively giving you access. She braces one hand on the wall for the pounding to come, squeezing a breast with the other.
"Oh yeah babe... you're gonna feel me all right... Nnnnrggh..." You lean forward again, reaching around to wrap your arms around her waist as slowly you push in; your blunt, flanged head forcing her engorged lips wide apart.
"Ahhhh ohhhhh goooood!"
Sean tosses her head back in ecstasy, tongue lolling out of the side of her parted jaws. You grunt as her tight tunnel squeezes around you. Teeth grit, you keep it slow, deliberate, both to draw out her first penetration and to make it easier on her. She has to put her other hand on the wall as well, barely able to stand under the assault of the massive beast pushing into her sensitive new passage.
"God babe you're so tight!" You huff deeply, feeling yourself throbbing and pumping out precum into her in response to her frantic contractions.
"You're sooo... big!" She pants, managing a lust-filled look over her shoulder. "Inside me...!"
You snort in satisfaction. "Yeah babe... and I'm not gonna hold back...! But you can take it! You are... made... for sex!"
"Yessssss..." She hisses, the compliment affirming her and making her love tunnel feel even better as your massive cock stretches it. "Ohhghh... give it to me Darryl... I want all of you..."
"All of me is... quite a lot," you snort as you push even deeper. "But you can take it, baby! take all of me, down to the hilt, and love every minute of it..."
"Yessss!" Trusting your strong hands to hold her up, she reaches back to her crotch, as your massive dick continues to impossibly slide in. "I feel you... so deep inside me...!"
"Balls deep," you rumble back, just as your hips meet hers, you over-filled balls pushing against her thighs. Her cervix flexes as your head caresses it, making her yowl in pleasure.
"Oh my God! Darryl... I can't... you're amazing...!" She shudders, reveling in the feelings of her pussy rippling along your unyielding length, already on the verge of orgasm again from the strangeness of the hot, wet embrace. She hadn't had much sex as a man, apart from masturbation -- but this is better than anything she could have imagined possible!
"I know I am," you acknoledge, before bending down and kissing her neck. "And so are -- nnngh -- you, my sexy vixen."
"Ahhhh... oh Darryl..." She takes your hands; both of you marvel at how much they different in size now, before she guides them up to her boobs. She whimpers as you gently squeeze them. Then she grinds her fat ass into your crotch, your cock spasming as she squeezes over it. "More," she begs. "Fuck me, Darryl. I need... I want you to take me like an animal."
"Guess you like furries after all, hmm?" you tease, and start to pull out. "Ohhh yeeaahhh... get ready for me to fucking breed you!"
Further speech was lost as you rapidly began to pick up the pace. There was nothing more but for both of you give into your bestial instincts, to be a rutting stallion and a vixen in heat. To revel in the feel of your balls slapping into her, the pliant fullness of her breasts as you roughly knead them. She keeps up gamely, her lithe body pushing back into your thrusts, her lusty moans and yips spurring you to piston your rod into her harder and harder. Little orgasms keep rocking through her as your cock rubs her g-spot, you pinch her nipples, and brush her clit; but it just builds her lust, always pushing towards another peak, until...
Finally you come, neighing in triumph as her voice rises in a mix of vixen and human scream. The feel of your first thick torrent of cum gushing against her womb throws her over the edge into an ecstatic free-fall through golden clouds and bursting stars, her whole female body reverberating with her pleasure and your mighty ejaculations.
Her boobs squish into your hands as her shuddering body goes limp. You cradle her to you, your massive phallus continuing to pump wave after wave of stallion seed into her fertile depths, until its flooding back out and running hotly over your balls and her thighs. You feel hot pride mingling with the pleasure of release; of a stallion claiming a woman; of a god who made a nervous, nerdy man into a sultry fox woman.
