Her fingers trailed gently along his firm erection, the sensation of his skin sending a shudder down her body, from the roots of her ears to the tip of her tail, ending in a warm pulse between her legs. She wrapped her hand around his shaft, slit eyes burrowing into his. "You realize, once you do this, there's no going back. Are you sure?"
He swallowed, his own eyes never wavering. "I'm sure."
She had to close her eyes and take a deep breath, steadying herself against the rush of pleasure that swept across her body. She felt his warmth under her hand as she squeezed, gently, drawing another shudder out of him. "Then..." She pulled along him, watching the flesh bunch up slightly under the motion. "We continue, and you surrender that humanity."
He reached out, his own warm hand caressing the side of her face, and she turned her head to nip gently at the fingers. She opened her eyes, gazing into his. The lust was there in his eyes, the desire that he'd so clearly had for months. "Such an eager one."
She trailed lowered her hand, claws trailing gently across his balls as little prickles aside of her sharp claws teased at his skin. He knew he was entering something larger than a fun evening, something larger than just a night. She had to wonder if he really knew what he was doing. And then she smiled to herself as his hands found the sides of her breasts and caressed her nipples, and her tail lashed and she murred at the sensation.
Did it matter? She nuzzled into his neck, tossing aside those heavy thoughts. The warmth in her chest and between her legs was telling her to get on with the show. To enjoy him, as she had so often over these last few months. He was a fine playmate. "You aren't going in, my stud." She brought her hand, teasing with the very furry tips along his pole. "Not tonight. Not until after."
His hands stroked down her belly, fingers teasing between her thighs. Her ears perked, her eyes widening. "No, my dear. Not yet." Her claws danced along his shaft as she made more room. "Tonight is all about you, mmm, sweet thing. Every moment. Let me worship you." Her hands slid down his thighs as she nuzzled his chest, her lips and whiskers kissing along the firm musculature of his body.
His scent was rich in her nose, a hint of soap and musk and sweat from the day's exertions. "You're not a bad looker, for a human."
"I can be more." He thrust his hips up against her hands. "I'll be whatever you want."
"Don't make those kinds of promises!" Her tailtip teased along his cock as her hands found the inside of his thighs. "I'm not some innocent young girl. I'm a demon." Her tongue trailed up his belly, her eyes twinkling. "And you're giving me too much power. It's intoxicating." Her tongue trailed higher. "And I'm not a lightweight." She grinned as her hands slipped behind him, caressing his ass. "You should know this about me, my pet." Her tongue trailed across the hollow of his neck, her hot breath making his skin glisten.
He tried to grab her, to do something with her, but she was deceptively strong, easily rebuffing his attempts. "No. Not tonight." Her hands kneaded his ass. "Tonight, I'm the only one who gets to do anything. You're mine." She nipped at his collarbone, then ran her rough tongue over the red spot. "Relax, except that part. That part can keep being nice and tense, all the way to the end." Her tongue trailed lower, and the warmth of it flickered against the base of his cock, and her eyes looked up at him. She was teasing, but her eyes were filled with an earnest love that was nearly overwhelming.
He had surrendered to her, entirely. She knew it, and felt sure he did too. She just had to take what he was presenting to her. It was not a gift that she intended to squander. She would take this night and make it a night to remember, a moment that he would look back on as the night when everything changed.
Her furry hand pulled along his length. "Feel that first little squirt?" He was leaking a thin line of prefluids. "Your weakness is already coming free of you." Her lips pursed in a kiss, her tongue snaking out and flickering across his tip, sending a shudder down his body. "I love how responsive you are, my dear." She stroked along the top of his shaft as her tongue trailed lower.
"This, the spigot." She kissed the side of his shaft. "The first to change." Her hand slid up and down his shaft as it started to stiffen further, the blood throbbing under his skin. She felt the heat of his shaft on her cheek, his scent rich in her nose. His hips bucked, and her fingers tightened on the back of his balls. "Come on, my sweet thing."
The hair in the area began to grow thicker, becoming a proper pelt that spread across his sack. "Good boy, that's it." She could feel the changes as they spread through his flesh. "Let that happen." She grinned up at him, her eyes twinkling. "Don't resist, my dear."
Her eyes gleamed as a smile spread, watching as the fur bunched up near the base of his shaft, drawing his foreskin down away from the tip to form a sheath. The change was spreading faster, now. "Good, good boy. You're getting there, aren't you." The fur on his balls had spread up along the base of his shaft to connect with the sheath. "That feels good, doesn't it." Her claws teased at the base of his sack, then drew up the shaft as it became covered with the fur.
"Last chance." She teased with slow circular rubs over his excited pole. "We could stop. You'll wake up tomorrow, can just pretend this was a freaky dream." Her hand slid down and gave his sack a tug. "Or we can go the rest of the way. I promise, though..." Her tongue flickered across his tip again, and his cock twitched. "You'll be mine. Forever."
He could feel his heart thumping in his chest. The sensation of the changes was like a thousand little touches across his skin. He grunted, thrusting against her touch once. "I." He thought of his life, and what it could be, with her. "Let's keep going, please."
Her tail lashed with excitement. "So be it." She wrapped her hand around his shaft, squeezing. "Now." Her tongue trailed across the tip of his length. "You're a man." She sank her mouth over the tip of his cock, her lips closing around the sheath. Her tongue slid along his shaft, and he moaned at the sensation. His balls were tight, and the warmth of her mouth was intoxicating. She bobbed her head slowly, letting him feel the way her tongue trailed across him, the sensation like electricity, and it was the center and entirety of his existence in that moment.
And the change swept over him. His cock began to shift, and she sucked harder as the shape of his tip shifted, becoming thicker and flatter. She could feel the blood rushing through him, the pressure of the growth against her mouth and tongue. His balls were shifting inside, growing larger and firmer, and her hand kneaded them through the changes, making the sensations sharper.
He was panting. The changes were so intense, he felt like he could explode at any moment, the sensations were so intense. Despite feeling like he was right at that line, release didn't come to him, only more changes that kept him pressed almost painfully against that line.
She drew free, licking his altered tip as her fingers teased a thick ridge that had developed near the center of his still growing shaft. "The dream of many a man, to have a real stud of a cock." She stroked the base as it thickened. "The core of his humanity." Her tongue flickered across the tip again. "Becoming what he thinks he wants it to be." She drew her hand up, and the sheath tightened as she slid it up the growing shaft.
"Just imagine, when we're done, maybe I'll let you use this massive thing on me." She grinned as he shuddered, and she stroked him. "You like that idea." She licked his tip, savoring the taste. "Maybe you've wanted this for a long time." He had, but she knew that already. "Wicked thing."
She played where his sheath met his still growing balls. "You know, the larger these grow, the more you've been desperately hoping for this day." Her tongue teased the tip of his shaft. "It's a bit like a dream come true, isn't it." His balls were continuing to grow in her hand. "I'm a little surprised." She tapped at them. "I didn't think they'd get quite _this_ large. I'm impressed." His cock was thickening, his balls growing heavier and rounder.
His shaft was growing in her hand, the skin feeling tight as the fur stretched. He could feel his pulse in it. She gave a firm pull at the shaft. "Mmm, I wonder if the rest of you will be a horse, or something else? I can't wait to see, sweet thing." She licked his tip, her hand stroking. "You're so close to your first release, aren't you?" Her tongue slid down to the base. "You've been waiting for this, the whole time, haven't you."
With a new sensation, raw power, his balls settled into their new size, like wielding bowling balls between his legs. Every motion of his thighs made them jostle around, and every motion of them set him on fire. She licked the shaft, her tongue trailing the length of it, and he shuddered. "No, not yet." She grinned up at him, her tongue sliding along his cock. "You don't get to until the rest of you finishes. Let me help."
She nursed on him. The sensation was so intense, it felt like he could burst at any moment, but that moment never came. He felt the pressure of her tongue on his tip, the warmth of her mouth on the base of his shaft. Each firm suckle drew something precious from him, replacing it with more of the wild beast she had promised him.
His hands clenched at the sheets as her tongue slid along him, her hand working his balls. His toes curled as she teased a line from base to tip, her hand working the sheath. She knew exactly how to play his body. Even if that body was changing. The fur at his groin was inching up and down, spreading across his thighs. His hips and legs were aching as they began to change.
"Your knees will reverse. The legs of the animal, to handle your power." Her hands squeezed his thighs. "To hold your new form, not this weak thing."
They also bulged, his muscles redoubling, reshaping, to the powerful limbs of a beast. He could feel the power of them. The power of a horse, to run, to kick. He could feel himself growing, as if his bones were growing, his whole body becoming larger to support the changes. It was still in his powerful thighs, but he could imagine the rest of him soon matching.
Her lips pursed around his tip and sucked, pulling his mind back from the sensations in his body to her. Her hand stroked along the top of his shaft as it continued to grow. "So much of your humanity is in your mind. And so much of that? Down here."
She nursed, coaxing him along as that change worked in waves of delightful tingles down his legs. His toes fused, and the fur wrapped them up as his ankles reversed and his legs became those of a stallion. Thick, powerful, and long. He could feel it, and he could see them, and his mind rebelled a little at the sight of them. This wasn't possible. And yet, here he was.
He kicked his new hooves, but she was still stronger, holding him so easily in place. "We're not done." He could feel a prickling in the small of his back. It was the fur, spreading across his flesh. It crept up his back as she worked his shaft.
It was like a cool, prickly blanket. "Time for you to get something no human gets to have." The tingling gathering at the base of his spine. It grew into an intense ache that filled his hips and back. A powerful shudder ran up his back, and he felt the eruption as a new limb began to grow. The bones were rapidly growing muscles and skin, becoming the short tail of a horse even as it grew longer hairs that would form the bulk of it behind him. She gave it a little tug, making him yelp.
"You'll get used to that." She grinned. "But not today. Today is all about you being my toy." She stroked him in a few slow motions, not sucking. "I'm feeling generous. Want to stop? You'll be a strange half-way freak if you do, but you won't be owned by me." Her eyes twinkled. "If you don't, I promise. We're going to the end, and you're going to love it, my pet."
Her tongue slid across the head of his cock, teasing him, making him ache. "Decide. Most don't give two chances. Thank me either way."
He had to grit his teeth. It was a hard decision. But the sensations of his body were intoxicating. The warmth of her hand and mouth on him was incredible. The aching in his body was almost unbearable. "Let's finish! I'll be yours, without a complaint."
She grinned. "That was what I was waiting to hear." She licked the head of his shaft, and the changes swept back over him. The fur spread up his body, washing over his belly as it trimmed with new muscles that were forming to support his new body. His hips ached as they reshaped to hold his new form. He could feel the changes altering the way he sat and stood. He would be a hell beast. Hers.
She brushed a hand up along his new fur. "So much fun to stroke a good pelt, isn't it?" Every touch of her fingers sent a little shiver across his skin. His body felt so sensitive, every tiny brush of her fur on his flesh felt electric. The fur was still spreading, covering his chest and belly.
His chest firmed with power as his muscles grew and reshaped. He imagined what he could do with them, starting with holding his lover and mistress. He reached for her, only to be gently swatted away. "You're not done." She grinned, then drew her mouth over his cock, nursing on him anew.
Her fingers trailed along his chest. "You've got some work to do. You're still a man in there." The nursing coaxed things along, the fur creeping up over his shoulders. His arms were itching and aching as the changes swept over him. His arms firmed, his biceps and triceps growing more solid and powerful as his shoulders broadened.
She drew off him, her hands stroking him. "You can't get much more human than your hands." She brushed over them, still naked as they were. "One of man's greatest gifts. I'm taking it." Her hand slid up his shaft. "And replacing them with something I like more." She squeezed him. "Do you want that?"
"Yes." His voice was husky, raw, like he'd been yelling. "Yes!"
She stroked more firmly, as if to finish him, but no finish came. When her lips met his flattened tip, the fur swept over his hands. His palms became leathery as he grew toe beans like an animal. Fur covered his hand where the new beans weren't, leaving him with still dexterous hands, but nothing that could be confused for a human's.
Her tongue drew across him again, and the changes continued. His head began to tingle as the fur spread up his neck, to his chin. His ears itched, and he reached to scratch, finding them larger, and at the wrong angle. "Time for you to give up the last little bits. Throne of the soul, give up your brain. You don't need it. You only need to be thinking of me, and the delightful life we have ahead of us."
She teased her tongue across his shaft. "You could have stopped. Any time before this, you could have stopped. Now? Now you're mine, and we both know it." She sucked on him, and the changes swept over his body, the fur reaching up over his face as his jaw ached, his teeth growing flatter and his face reshaping. The world seemed to change as his vision altered. The colors weren't as bright, but he could see more clearly in the dim light of the evening.
He gasped, his tongue running over his changing teeth as the changes finished sweeping over him. His new tail lashed behind him, his heavy balls and sheathed cock hanging between his thighs. The room felt cool in his fur. "Almost. Almost." She kissed the very end of him. "Almost. Savor how close we are."
She let her tongue trail along him, savoring the taste and power in her hand. "You're so ready to be mine, aren't you." Her eyes gleamed. "You've always wanted it, haven't you."
"Y-yes!" He barely got out as his ears erupted into fur and began reshape, growing inches steadily with every excited beat of his heart. She drew her mouth down to the base of his shaft, and the changes swept up to the last of him, the changes of his face finishing as his ears slid to the top of his new head, reshaping to those of his new equine nature.
His vision was blocked with the new snout he had, but with his humanity drained away, he was quickly forgetting to look there. It was just part of him, to be ignored.
But he didn't want to ignore it! He grabbed his new snout and felt his face, realizing it was all him, all real, that he was no longer human, no longer a man. He had become the creature she wanted him to be.
She let him go, and he collapsed, panting. "You look so cute, holding your face like that. My stud, you should be holding something far more important, don't you think?"
He nodded. He didn't know what else to do, his heart was racing. "It's so different." His voice was hoarse, husky. "I'm not me." His heart was thumping in his chest.
"Oh, but it is!" she got out in a seductive purr. "But 'me' has changed. This is you. You are mine, and now, dear stud, I expect you to do as the name implies, hm? You'll satisfy my itches, and help convert those who'd prefer to get plowed by a thick and ready horse instead of have a sleek little me pressed against them."
His hands slid down to his sheath, feeling it, feeling his new balls. It was all real. He couldn't put it in words, the feeling of the changes that had swept over his whole body. All he could boil it down to was, "Thank you." He took her cheeks in his altered hands and drew her in for a kiss that they both enjoyed.
It had been an evening for them both to remember.
