Used with permission.[/right]\n\n\n“There,” Gwendolyn said, “that should just about do it. I'm going to go ahead and get undressed. Wouldn't want to tear up my clothes when the transformation happens, now would I?” She immediately reached behind herself and started undoing the buttons down her dress – along the back, as was the elven fashion.\n\n“Of ... of course not.” Doug pursed his lips as he watched his girlfriend's dress beginning to go slack, almost ready to fall off. His friends all thought he was the luckiest bastard to have an elven girlfriend. Elves were renowned for their beauty – an elven [I]three[/I] would easily be equivalent to a normal human [I]nine[/I]. But that came at a price, one he'd learned only after getting into such a committed relationship: elves tended to have a naturally lower sex drive. Gwenny was more than passionate enough when she got into it ... but she rarely showed [I]any[/I] interest. Even just seeing her naked was a treat Doug enjoyed once every few months, at best.\n\nAnd that's why his eyes were locked on Gwenny's body when she shrugged off her dress. She wore absolutely nothing underneath, as was also apparently the elven fashion. Doug tried his best to keep his tongue from hanging out as he stared. Gwenny's slender shoulders were exposed first, followed quickly after by her [I]lovely[/I] breasts – so huge and soft! – and then the long, svelte curves of her belly, leading down to her naturally hairless pussy lips, her luscious hips, and her long, shapely legs. Just that moment made everything about dealing with an elven girlfriend worth it. Maybe his friends were right. Maybe he [I]was[/I] the luckiest bastard...\n\n“Can you go ahead and pour the final mix, dearest?” Gwenny turned and headed to the counter on the other side of her potion workroom. “I need to find the special crystal chalice to drink it from, or it's all for nothing.”\n\n“Uh... Uh-huh...” Doug licked his lips and fumbled for the bottles without looking down at them. He just [I]couldn't[/I] look away from the sight of Gwenny leaning down over the counter across the room. The way her ass stuck out made it all the more bodacious than usual, showing off her tight round cheeks and the perfect little arch of the gap between them ... even a bit of her pussy lips from behind. The potion ingredients poured from bottle to bottle, scarcely even half-noticed.\n\nShe turned around, the chalice in her hands, though Doug was far more focused on the way her tits jiggled. “There. Is the mix ready?”\n\n“Uh...”\n\n“Pay [I]attention[/I], dearest! This potion is a very ambitious and tricky one. Are you sure you got the mixture right, as it says in the instructions?”\n\nDoug looked down at what he'd been doing. “Um... Uh-huh.”\n\nAs she came over, she bent down to look closely at the bottle ... and the way her breasts hung down beneath her didn't help alleviate his distractedness.\n\nBut she seemed satisfied with what she saw. “Okay, here it goes.” She raised the small bottle and poured its contents into her chalice. “The Aliformi Equii potion. The council will [I]have[/I] to recognize me as a Master Potioneer if [I]this[/I] works!”\n\nDoug didn't ask what was so important about being a Master Potioneer or even why his girlfriend had decided to temporarily turn herself into a horse. This was, as he'd learned, just kind of par for the course when it came to elves. They tended to have rather esoteric interests and a [I]very[/I] different idea of what was practical and useful.\n\n“Well, wish me luck!”\n\n“Uh...” Her naked body was still very much a distraction. “Are you sure it's safe to—?”\n\n“Yes, yes. I measured everything out quite exactly.” She held the chalice to her lips, grimaced, and then quickly downed everything inside.\n\nThe effect was immediate. Gwenny shot upward. At first, all Doug noticed was the incredible way her big soft tits bounced after she reached her new height, but as his eyes instinctively darted down to look at her perfectly pert pussy again, he saw no such thing. Instead, the lower half of her body had taken on a quite different shape, and was now covered in short brown fur. [I]That[/I] was enough to finally shock him out of the daze that seeing her naked had put him in.\n\n“You're...” He sputtered. “You're a horse!”\n\nShe looked down at herself, twisting her torso left and right as she took it all in. “Only [I]half[/I] horse. Are you sure you mixed the ingredients [I]exactly[/I] as the instructions said?”\n\n“Uh...”\n\n“[I]You![/I]” She bent down and jabbed a finger at his face. “You messed it up, didn't you? The instructions were [I]so[/I] simple! How could you possibly—?” Her eyes glanced down to where his were looking: straight across at her tits. “Oh.” She snorted, a surprisingly horse-like sound. “Of course. Humans, always in heat.”\n\n“I, um...”\n\n“No, don't say anything. No excuses. Honestly, I should have expected as much. A Master Potioneer should know better than to rely upon inexperienced and distracted assistants.”\n\n“Gwenny, I am [I]so[/I] sorry. I just...”\n\n“No, I told you – no excuses.” She leaned down close to him and kissed him on the forehead. With her so much taller than him now, it felt almost like she was an adult and he was a little kid again. “I truly [I]should[/I] have anticipated the effect seeing me would have on a human male.” She smiled sweetly and took half a step closer. “Here, go ahead and have a little touch.”\n\nHe was [I]not[/I] about to turn down an invitation like that! Right away, he reached up and cupped two overflowing handfuls of warm, soft tits. Gwenny actually gasped a little at the feeling of being touched that way.\n\nOdd, she'd normally never do that kind of thing for him unless she was in one of the [I]very[/I] rare occasions when she was in the mood. Had turning half her body into a horse somehow increased her sex drive as well? Doug wasn't about to ask too many questions about that. He just ignored her incredibly fine tits for as long as she'd let him.\n\nUnfortunately, that wasn't very long. After just a few moments, she turned around – a much more theatrical movement now that she had four legs – and went back to rummaging through the cabinet on the other side of the room.\n\nDoug still felt like he owed her more than just a lame apology, though. He held up one of the bottles. “Uh, there's still some left here, if you want to try it again...”\n\nShe lifted her human half back up and looked over her shoulder at him. “That's all well and good, but I need to find my universal potion of undoing first, to cancel out the effects I already have. I do [I]not[/I] want to grow an additional horse body on top of this one. Nobody at the academy is going to be impressed if I end up turning myself into a six-legged horse when my upper body is transformed as well.”\n\nAs she sifted through the cabinet's disorganized drawers, Doug came up closer behind her. At first, he only intended to help her look for that potion, but the closer he came, the higher Gwenny's new tail rose. And underneath that tail...\n\nGwenny's horsey rump was [I]huge[/I]. Far larger than her elven features had once been. But he couldn't deny that there was still a certain shapeliness to her chestnut-furred curves. Big, powerful leg muscles with well-defined grooves curving up into a surprisingly prim and upturned ass ... and her horse pussy was just right [I]there[/I], tantalizingly in front of him: a smooth-skinned teardrop bulb that just looked [I]so[/I] soft and delicate... As he came closer still, her pussy actually winked open, showing a brief flash of the hot pink inside, as well as a big heart-shaped clit jutting upward from the bottom of her slit for a second. A little bit of milky-clear juices trickled down over her clit as her pussy closed back up.\n\n“What in the world was—?” Gwenny looked behind herself again, seeing Doug there. “Oh, it's you. And this horse body ... I think it's responding to your pheromones or something. Is it...? Am I [I]in heat?[/I]”\n\n[I]Now[/I] the way Gwenny gratuitously let him play with her breasts made more sense. “Well, it [I]is[/I] springtime...”\n\n“Just my luck.” She shook her head. “[I]Another[/I] thing I should have anticipated beforehand. I [I]really[/I] need to find that undoing potion.”\n\n“Uh...”\n\nShe glanced back at him again. “[I]What is it?[/I]” Her horsey pussy winked again, longer and more insistently this time.\n\n“We don't, uh... We don't have to undo it [I]right away[/I], do we?”\n\n“Huh? Of course we—” Her eyes glanced down, and she saw the bulge growing in his pants. “What? You're [I]ridiculous[/I], you know that? How could you even want...?” Her pussy winked again, in a staccato series of pulses that left her juices dripping down onto the smooth workroom floor. She let out a wordless little gasp of primal need.\n\nDoug pursed his lips together for a moment, wondering if he should dare. Of course you should, his cock told him. “I could, uh, help you with that, if you want...”\n\nHer tail rose [I]all[/I] the way up and flipped to the side. More flashes of pink winked out below it. “F-fine!” she eventually spat out. “Just remember, I'm only doing this because you're so weirdly obsessed with it. It's not as if I have even the [I]slightest[/I]—”\n\nHer words cut off into a sudden intake of breath as Doug reached out and touched her pussy. It was even nicer than he'd expected. So warm, and the skin of it was silky-smooth. It felt so wonderful to trace his fingers over that dark brown bulb of hers. And when he pressed just a little harder, he was surprised at the wonderful springy softness – it actually reminded him of his old ex-girlfriend's tits. They'd been much smaller, but also firmer than Gwenny's, and the way they yielded under his fingers was [I]just[/I] like the thick, juicy lips of Gwenny's horse pussy now.\n\nAnd when her pussy winked open again, he took that as an invitation, touching the slick and smooth inner walls of her pussy as they winked open for him. Gwenny gasped at the touch, even whimpered a little, but she didn't actually say anything.\n\nNot that she needed to. The syrupy juices coating his fingers were more than message enough for Doug. Even though her pussy closed back up again around his fingertips, he had no problem sliding two fingers deeper into her pussy. And the next time her clit winked out at him, he quickly bent down and licked it, which only triggered more and stronger winks, not to mention a little waterfall of hot juices trickling down on him.\n\nWith his free hand he reached down and started touching himself, already wondering what it would feel like to have those wonderful horsey pussy lips winking around his shaft.\n\nGwenny must have noticed him doing that because she said, “Ugh, [I]fine[/I]. Go ahead. I know you won't be happy until you've done it.” Her hind legs spread apart a little wider, and the entrance of her pussy winked feverishly around his fingers.\n\nAs much fun as it might have been to tease her about it, Doug knew better than to second-guess an invitation from his elven – now centaur? – girlfriend. Right away, he unbuttoned his pants and pulled them down along with his underwear. He stepped out of them hastily, and...\n\nAnd he was [I]way[/I] too short. Laughably so. Even if he stood up on tip-toes, he'd barely reach high enough to touch the very base of Gwenny's ass cheeks with his tip. “Um...”\n\nGwenny rolled her eyes at him. “There's a stool on the other side of the workbench.”\n\nDoug had never moved so fast while sporting a boner before. It bounced in front of him as he dashed around, grabbed the stool, and returned. And now that he stood up on the stool, things were at [I]just[/I] the right height. Grabbing his cock, he rubbed the tip of it up and down over Gwenny's horsey slit.\n\nHe could tell she was stifling a moan, holding it back by sheer force of will. But rather than letting [I]that[/I] out, she gave a frustrated-sounding huff. “What are you waiting for? Let's get this over with! [I]Please![/I]”\n\nWhen her pussy winked open, it all but swallowed his cock without him doing anything. One moment, his tip was up against her slit, and the next, it was pressing against her hot, slick inner walls. And before he even realized that, her pussy lips closed around him again, surrounding his tip with warmth and softness. Well, why not? He pushed a bit more, sliding his cock into her. It slid up easily deeper inside, all the way until he hilted himself inside her.\n\nHe had more than enough room to spare. Even at his very deepest, he could Just barely feel her inner walls coming to some kind of deeper barrier inside her, a little warm ring that he could only touch, not penetrate. But that hardly mattered. What mattered was the feeling of being completely surrounded by Gwenny's sumptuous warmth, the feeling of her pussy lips winking and pulsing around his base, and the feeling of her clit thrusting outward to kiss wetly against the front of his balls.\n\nAfter that, it was [I]on[/I]. He grabbed her big horsey ass with both hands and began thrusting into her freely, enjoying her new body to the utmost. She [I]was[/I] surprisingly good like this. Not very tight, of course, but [I]very[/I] soft and warm and inviting.\n\nEven as he [I]really[/I] started getting into it, though, Gwenny rarely made anything more than a soft, half-satisfied coo. Her tail flicked against his belly, and she kept bracing as if expecting something more, but he was already giving her everything he possibly could. \n\nWell, [I]he[/I] could enjoy it, though! He rubbed the big firm curves of her ass as he pounded his cock recklessly into her. Normally with Gwenny, he had to be very careful and slow – elves notoriously tend to be small and delicate down below, and Gwenny was no exception. His human cock could easily be too much for her to handle if he wasn't as gentle with her as he possibly could be. But [I]now[/I]... Now he could [I]slam[/I] his cock into Gwenny's horse pussy without even the slightest concern that he might hurt her. If anything, the little sounds she made suggested that she wanted [I]more[/I].\n\nHe only had so much to give, though, and thanks to being pent up for quite a while due to her lower libido, he could already feel himself working up to a climax.\n\n“I'm...” He huffed, leaning down low over her rump as he pushed as deeply as he could, actually beginning to penetrate that deeper ring of hers now that his cock had swollen to its utmost. “I'm gonna...”\n\nSmiling, she twisted her elven upper body sideways and reached back to run a hand through his hair. With her other hand, she held and kneaded her own breast, right where she could be sure he'd see it.\n\nThat was all it took. Doug locked himself tightly in place against Gwenny's horsey rump and pushed his cock as deep as he could possibly go. Her pussy lips pulsed and squeezed around his base, helping milk every last bit out of him as he came.\n\nAnd did he ever! Few orgasms in his life had been so satisfying as this one. Something about being able to jam inside her as deeply as he pleased triggered a primal drive inside him, and he truly emptied himself into her, releasing spurt after spurt.\n\nWhen he'd finally spent himself completely and fell down against Gwenny's broad, warm, furry back, she reached behind herself and patted him on the head. “Oh my... You are just [I]so[/I] cute when you're like that.”\n\nHe looked up at her and grinned dumbly.\n\n“But you [I]are[/I] going to make sure I enjoy it just as much, aren't you?”\n\nSlowly, he slid off her back. His cock plopped out of her pussy, and he stepped down off the stool. “But ... I thought you didn't want any and you were just doing it for me?”\n\nHer still-winking pussy and the way it dripped juices – now slightly milkier – already told him everything. But Gwenny herself disagreed: “It's not as if I [I]need[/I] it or anything, but I won't go instilling bad habits in any boyfriend of mine. You've had your fun, and now it's your responsibility to make sure I enjoy it just as much as you did.”\n\nWell, okay. Close enough for him. Doug scooted the stool out of the way with his foot. He wasn't about to lick her again, not with his own cum still dripping from her pussy, but he had no problem touching her.\n\nThis time, it was even easier to slip his fingers inside her, with plenty of slick, gooey warmth to go around. He made a swirling motion just inside her entrance, just how he knew she liked.\n\nThat [I]did[/I] get a few little appreciative sounds from her, and her hind legs shifted a bit to spread even more ... but it wasn't quite the reaction he was used to getting from her when he used his fingers.\n\nOf course! Well, her pussy was quite a bit bigger now. Maybe she just needed a bit more. Doug paused his motions for a moment to slip two more fingers inside her, enveloping all four fingers of one hand into her horsey slit. \n\nA little better – she moaned slightly, but it still seemed like she wanted more.\n\nHe pushed a little deeper, even getting a little bit of his thumb inside, too.\n\nGwenny leaned back against him, but he let her push him backward. He was already almost fisting her – he had almost his entire hand inside! – and he could feel that puffy little ring her pussy narrowed into at its very deepest. He didn't want to hurt her, after all!\n\nWhen she twisted her upper body around to look at him, though, there was genuine need in her eyes. “Stop teasing me already and [I]do it![/I]”\n\nDo it? Do [I]what?[/I] She wanted more than he was already doing? Well, if she asked for it, he'd try.\n\nThis time when she pressed back against his hand, he held himself firmly in place. He slid a little deeper in. His middle finger teased that innermost ring and found a little hole in the middle.\n\nThe moment he touched [I]that[/I], Gwenny let out a horse-like huff and pushed back [I]hard[/I]. Doug was already poised to push back against her. He didn't have time to switch his mindset to giving way.\n\nIt turned out, though, that he didn't really [I]need [/I]to give way. Though that little ring had seemed [I]quite[/I] small when he touched it, the force of Gwenny's push against him [I]easily[/I] forced all four of his fingers into it, stretching tightly. It was [I]barely[/I] enough room to squeeze his hand through, but his hand [I]did[/I] go through.\n\nGwenny let out a deeply satisfied sigh as the thickest part of his hand squeezed deeper into her. His wrist was already enveloped, and his forearm seemed sure to follow. But [I]inside[/I]...\n\nDoug had never felt anything like it. Beyond what he'd [I]thought[/I] was Gwenny's innermost barrier, his hand slipped into a wide, sumptuously soft and warm place that surrounded and molded around him on all sides. That tight, squeezing pressure was gone, now around his wrist instead, and all that was left was ... [I]wow[/I]. “[I]Gwenny[/I]...” he said in soft disbelief.\n\n“[I]Deeper[/I],” she moaned.\n\nEven deeper than [I]this?[/I] “Uh ... are you sure?”\n\n“Deeper!”\n\n“Okay...” He pushed a little more. His forearm slipped between her pussy lips, and his hand glided through that incredible wet warmth deep inside her pussy.\n\nHe could even spread his fingers apart in there. And when he did, Gwenny moaned again.

He could feel the heat rolling off of her, almost as much as he could feel it around his hand inside of her.\n\nOkay. [I]Maybe[/I] he'd overdone it a little.\n\nSlowly and gingerly, he drew his hand out of her horsey pussy.

Then her eyes locked onto his. “I ... I need [I]more![/I]”\n\n[I]That[/I] was a side of her he'd never seen before! “More? I don't know if there's any more I can—”\n\n“No!

“There,” Gwendolyn said, “that should just about do it. I'm going to go ahead and get undressed. Wouldn't want to tear up my clothes when the transformation happens, now would I?” She immediately reached behind herself and started undoing the buttons down her dress – along the back, as was the elven fashion.

“Of ... of course not.” Doug pursed his lips as he watched his girlfriend's dress beginning to go slack, almost ready to fall off. His friends all thought he was the luckiest bastard to have an elven girlfriend. Elves were renowned for their beauty – an elven three would easily be equivalent to a normal human nine. But that came at a price, one he'd learned only after getting into such a committed relationship: elves tended to have a naturally lower sex drive. Gwenny was more than passionate enough when she got into it ... but she rarely showed any interest. Even just seeing her naked was a treat Doug enjoyed once every few months, at best.

And that's why his eyes were locked on Gwenny's body when she shrugged off her dress. She wore absolutely nothing underneath, as was also apparently the elven fashion. Doug tried his best to keep his tongue from hanging out as he stared. Gwenny's slender shoulders were exposed first, followed quickly after by her lovely breasts – so huge and soft! – and then the long, svelte curves of her belly, leading down to her naturally hairless pussy lips, her luscious hips, and her long, shapely legs. Just that moment made everything about dealing with an elven girlfriend worth it. Maybe his friends were right. Maybe he was the luckiest bastard...

“Can you go ahead and pour the final mix, dearest?” Gwenny turned and headed to the counter on the other side of her potion workroom. “I need to find the special crystal chalice to drink it from, or it's all for nothing.”

“Uh... Uh-huh...” Doug licked his lips and fumbled for the bottles without looking down at them. He just couldn't look away from the sight of Gwenny leaning down over the counter across the room. The way her ass stuck out made it all the more bodacious than usual, showing off her tight round cheeks and the perfect little arch of the gap between them ... even a bit of her pussy lips from behind. The potion ingredients poured from bottle to bottle, scarcely even half-noticed.

She turned around, the chalice in her hands, though Doug was far more focused on the way her tits jiggled. “There. Is the mix ready?”

“Uh...”

“Pay attention, dearest! This potion is a very ambitious and tricky one. Are you sure you got the mixture right, as it says in the instructions?”

Doug looked down at what he'd been doing. “Um... Uh-huh.”

As she came over, she bent down to look closely at the bottle ... and the way her breasts hung down beneath her didn't help alleviate his distractedness.

But she seemed satisfied with what she saw. “Okay, here it goes.” She raised the small bottle and poured its contents into her chalice. “The Aliformi Equii potion. The council will have to recognize me as a Master Potioneer if this works!”

Doug didn't ask what was so important about being a Master Potioneer or even why his girlfriend had decided to temporarily turn herself into a horse. This was, as he'd learned, just kind of par for the course when it came to elves. They tended to have rather esoteric interests and a very different idea of what was practical and useful.

“Well, wish me luck!”

“Uh...” Her naked body was still very much a distraction. “Are you sure it's safe to—?”

“Yes, yes. I measured everything out quite exactly.” She held the chalice to her lips, grimaced, and then quickly downed everything inside.

The effect was immediate. Gwenny shot upward. At first, all Doug noticed was the incredible way her big soft tits bounced after she reached her new height, but as his eyes instinctively darted down to look at her perfectly pert pussy again, he saw no such thing. Instead, the lower half of her body had taken on a quite different shape, and was now covered in short brown fur. That was enough to finally shock him out of the daze that seeing her naked had put him in.

“You're...” He sputtered. “You're a horse!”

She looked down at herself, twisting her torso left and right as she took it all in. “Only half horse. Are you sure you mixed the ingredients exactly as the instructions said?”

“Uh...”

“You!” She bent down and jabbed a finger at his face. “You messed it up, didn't you? The instructions were so simple! How could you possibly—?” Her eyes glanced down to where his were looking: straight across at her tits. “Oh.” She snorted, a surprisingly horse-like sound. “Of course. Humans, always in heat.”

“I, um...”

“No, don't say anything. No excuses. Honestly, I should have expected as much. A Master Potioneer should know better than to rely upon inexperienced and distracted assistants.”

“Gwenny, I am so sorry. I just...”

“No, I told you – no excuses.” She leaned down close to him and kissed him on the forehead. With her so much taller than him now, it felt almost like she was an adult and he was a little kid again. “I truly should have anticipated the effect seeing me would have on a human male.” She smiled sweetly and took half a step closer. “Here, go ahead and have a little touch.”

He was not about to turn down an invitation like that! Right away, he reached up and cupped two overflowing handfuls of warm, soft tits. Gwenny actually gasped a little at the feeling of being touched that way.

Odd, she'd normally never do that kind of thing for him unless she was in one of the very rare occasions when she was in the mood. Had turning half her body into a horse somehow increased her sex drive as well? Doug wasn't about to ask too many questions about that. He just ignored her incredibly fine tits for as long as she'd let him.

Unfortunately, that wasn't very long. After just a few moments, she turned around – a much more theatrical movement now that she had four legs – and went back to rummaging through the cabinet on the other side of the room.

Doug still felt like he owed her more than just a lame apology, though. He held up one of the bottles. “Uh, there's still some left here, if you want to try it again...”

She lifted her human half back up and looked over her shoulder at him. “That's all well and good, but I need to find my universal potion of undoing first, to cancel out the effects I already have. I do not want to grow an additional horse body on top of this one. Nobody at the academy is going to be impressed if I end up turning myself into a six-legged horse when my upper body is transformed as well.”

As she sifted through the cabinet's disorganized drawers, Doug came up closer behind her. At first, he only intended to help her look for that potion, but the closer he came, the higher Gwenny's new tail rose. And underneath that tail...

Gwenny's horsey rump was huge. Far larger than her elven features had once been. But he couldn't deny that there was still a certain shapeliness to her chestnut-furred curves. Big, powerful leg muscles with well-defined grooves curving up into a surprisingly prim and upturned ass ... and her horse pussy was just right there, tantalizingly in front of him: a smooth-skinned teardrop bulb that just looked so soft and delicate... As he came closer still, her pussy actually winked open, showing a brief flash of the hot pink inside, as well as a big heart-shaped clit jutting upward from the bottom of her slit for a second. A little bit of milky-clear juices trickled down over her clit as her pussy closed back up.

“What in the world was—?” Gwenny looked behind herself again, seeing Doug there. “Oh, it's you. And this horse body ... I think it's responding to your pheromones or something. Is it...? Am I in heat?”

Now the way Gwenny gratuitously let him play with her breasts made more sense. “Well, it is springtime...”

“Just my luck.” She shook her head. “Another thing I should have anticipated beforehand. I really need to find that undoing potion.”

“Uh...”

She glanced back at him again. “What is it?” Her horsey pussy winked again, longer and more insistently this time.

“We don't, uh... We don't have to undo it right away, do we?”

“Huh? Of course we—” Her eyes glanced down, and she saw the bulge growing in his pants. “What? You're ridiculous, you know that? How could you even want...?” Her pussy winked again, in a staccato series of pulses that left her juices dripping down onto the smooth workroom floor. She let out a wordless little gasp of primal need.

Doug pursed his lips together for a moment, wondering if he should dare. Of course you should, his cock told him. “I could, uh, help you with that, if you want...”

Her tail rose all the way up and flipped to the side. More flashes of pink winked out below it. “F-fine!” she eventually spat out. “Just remember, I'm only doing this because you're so weirdly obsessed with it. It's not as if I have even the slightest—”

Her words cut off into a sudden intake of breath as Doug reached out and touched her pussy. It was even nicer than he'd expected. So warm, and the skin of it was silky-smooth. It felt so wonderful to trace his fingers over that dark brown bulb of hers. And when he pressed just a little harder, he was surprised at the wonderful springy softness – it actually reminded him of his old ex-girlfriend's tits. They'd been much smaller, but also firmer than Gwenny's, and the way they yielded under his fingers was just like the thick, juicy lips of Gwenny's horse pussy now.

And when her pussy winked open again, he took that as an invitation, touching the slick and smooth inner walls of her pussy as they winked open for him. Gwenny gasped at the touch, even whimpered a little, but she didn't actually say anything.

Not that she needed to. The syrupy juices coating his fingers were more than message enough for Doug. Even though her pussy closed back up again around his fingertips, he had no problem sliding two fingers deeper into her pussy. And the next time her clit winked out at him, he quickly bent down and licked it, which only triggered more and stronger winks, not to mention a little waterfall of hot juices trickling down on him.

With his free hand he reached down and started touching himself, already wondering what it would feel like to have those wonderful horsey pussy lips winking around his shaft.

Gwenny must have noticed him doing that because she said, “Ugh, fine. Go ahead. I know you won't be happy until you've done it.” Her hind legs spread apart a little wider, and the entrance of her pussy winked feverishly around his fingers.

As much fun as it might have been to tease her about it, Doug knew better than to second-guess an invitation from his elven – now centaur? – girlfriend. Right away, he unbuttoned his pants and pulled them down along with his underwear. He stepped out of them hastily, and...

And he was way too short. Laughably so. Even if he stood up on tip-toes, he'd barely reach high enough to touch the very base of Gwenny's ass cheeks with his tip. “Um...”

Gwenny rolled her eyes at him. “There's a stool on the other side of the workbench.”

Doug had never moved so fast while sporting a boner before. It bounced in front of him as he dashed around, grabbed the stool, and returned. And now that he stood up on the stool, things were at just the right height. Grabbing his cock, he rubbed the tip of it up and down over Gwenny's horsey slit.

He could tell she was stifling a moan, holding it back by sheer force of will. But rather than letting that out, she gave a frustrated-sounding huff. “What are you waiting for? Let's get this over with! Please!”

When her pussy winked open, it all but swallowed his cock without him doing anything. One moment, his tip was up against her slit, and the next, it was pressing against her hot, slick inner walls. And before he even realized that, her pussy lips closed around him again, surrounding his tip with warmth and softness. Well, why not? He pushed a bit more, sliding his cock into her. It slid up easily deeper inside, all the way until he hilted himself inside her.

He had more than enough room to spare. Even at his very deepest, he could Just barely feel her inner walls coming to some kind of deeper barrier inside her, a little warm ring that he could only touch, not penetrate. But that hardly mattered. What mattered was the feeling of being completely surrounded by Gwenny's sumptuous warmth, the feeling of her pussy lips winking and pulsing around his base, and the feeling of her clit thrusting outward to kiss wetly against the front of his balls.

After that, it was on. He grabbed her big horsey ass with both hands and began thrusting into her freely, enjoying her new body to the utmost. She was surprisingly good like this. Not very tight, of course, but very soft and warm and inviting.

Even as he really started getting into it, though, Gwenny rarely made anything more than a soft, half-satisfied coo. Her tail flicked against his belly, and she kept bracing as if expecting something more, but he was already giving her everything he possibly could.

Well, he could enjoy it, though! He rubbed the big firm curves of her ass as he pounded his cock recklessly into her. Normally with Gwenny, he had to be very careful and slow – elves notoriously tend to be small and delicate down below, and Gwenny was no exception. His human cock could easily be too much for her to handle if he wasn't as gentle with her as he possibly could be. But now... Now he could slam his cock into Gwenny's horse pussy without even the slightest concern that he might hurt her. If anything, the little sounds she made suggested that she wanted more.

He only had so much to give, though, and thanks to being pent up for quite a while due to her lower libido, he could already feel himself working up to a climax.

“I'm...” He huffed, leaning down low over her rump as he pushed as deeply as he could, actually beginning to penetrate that deeper ring of hers now that his cock had swollen to its utmost. “I'm gonna...”

Smiling, she twisted her elven upper body sideways and reached back to run a hand through his hair. With her other hand, she held and kneaded her own breast, right where she could be sure he'd see it.

That was all it took. Doug locked himself tightly in place against Gwenny's horsey rump and pushed his cock as deep as he could possibly go. Her pussy lips pulsed and squeezed around his base, helping milk every last bit out of him as he came.

And did he ever! Few orgasms in his life had been so satisfying as this one. Something about being able to jam inside her as deeply as he pleased triggered a primal drive inside him, and he truly emptied himself into her, releasing spurt after spurt.

When he'd finally spent himself completely and fell down against Gwenny's broad, warm, furry back, she reached behind herself and patted him on the head. “Oh my... You are just so cute when you're like that.”

He looked up at her and grinned dumbly.

“But you are going to make sure I enjoy it just as much, aren't you?”

Slowly, he slid off her back. His cock plopped out of her pussy, and he stepped down off the stool. “But ... I thought you didn't want any and you were just doing it for me?”

Her still-winking pussy and the way it dripped juices – now slightly milkier – already told him everything. But Gwenny herself disagreed: “It's not as if I need it or anything, but I won't go instilling bad habits in any boyfriend of mine. You've had your fun, and now it's your responsibility to make sure I enjoy it just as much as you did.”

Well, okay. Close enough for him. Doug scooted the stool out of the way with his foot. He wasn't about to lick her again, not with his own cum still dripping from her pussy, but he had no problem touching her.

This time, it was even easier to slip his fingers inside her, with plenty of slick, gooey warmth to go around. He made a swirling motion just inside her entrance, just how he knew she liked.

That did get a few little appreciative sounds from her, and her hind legs shifted a bit to spread even more ... but it wasn't quite the reaction he was used to getting from her when he used his fingers.

Of course! Well, her pussy was quite a bit bigger now. Maybe she just needed a bit more. Doug paused his motions for a moment to slip two more fingers inside her, enveloping all four fingers of one hand into her horsey slit.

A little better – she moaned slightly, but it still seemed like she wanted more.

He pushed a little deeper, even getting a little bit of his thumb inside, too.

Gwenny leaned back against him, but he let her push him backward. He was already almost fisting her – he had almost his entire hand inside! – and he could feel that puffy little ring her pussy narrowed into at its very deepest. He didn't want to hurt her, after all!

When she twisted her upper body around to look at him, though, there was genuine need in her eyes. “Stop teasing me already and do it!”

Do it? Do what? She wanted more than he was already doing? Well, if she asked for it, he'd try.

This time when she pressed back against his hand, he held himself firmly in place. He slid a little deeper in. His middle finger teased that innermost ring and found a little hole in the middle.

The moment he touched that, Gwenny let out a horse-like huff and pushed back hard. Doug was already poised to push back against her. He didn't have time to switch his mindset to giving way.

It turned out, though, that he didn't really need to give way. Though that little ring had seemed quite small when he touched it, the force of Gwenny's push against him easily forced all four of his fingers into it, stretching tightly. It was barely enough room to squeeze his hand through, but his hand did go through.

Gwenny let out a deeply satisfied sigh as the thickest part of his hand squeezed deeper into her. His wrist was already enveloped, and his forearm seemed sure to follow. But inside...

Doug had never felt anything like it. Beyond what he'd thought was Gwenny's innermost barrier, his hand slipped into a wide, sumptuously soft and warm place that surrounded and molded around him on all sides. That tight, squeezing pressure was gone, now around his wrist instead, and all that was left was ... wow. “Gwenny...” he said in soft disbelief.

“Deeper,” she moaned.

Even deeper than this? “Uh ... are you sure?”

“Deeper!”

“Okay...” He pushed a little more. His forearm slipped between her pussy lips, and his hand glided through that incredible wet warmth deep inside her pussy.

He could even spread his fingers apart in there. And when he did, Gwenny moaned again. All along the bottom and the sides, it was just softness, softness, and more softness, but if he pressed upward, he could feel the round shape of the inside of her ass ... but Gwenny didn't seem to like that, so he focused on just slipping his hand in deeper.

He almost had his elbow inside her pussy when he finally found the limit to Gwenny's depths. And as his fingers pressed there, he felt an odd little nub sticking up from the bottom ... almost like a little shark fin shape. Curious about what that was, he touched it some more, rubbing his fingers along it.

Gwenny stiffened instantly. At first, he thought he'd hurt her, but when she let out a louder, less inhibited moan, he recognized the tone in her voice. That sounded just like the times he'd played with her extra-sensitive elven clit on the few occasions they'd made love before!

Could that be what she needed so badly? Gently at first, but then more firmly, he started deliberately rubbing that little nub.

It got a reaction out of her much more quickly than he expected. Right away, she started breathing more heavily – both her elven chest and her horsey flanks heaved with every motion his fingers made. Her pussy began to squeeze a little tighter around his arm.

He didn't let up. And just to enhance it a bit more, he began moving his whole arm in and out of her pussy as he rubbed that little bump of hers more and more.

When Gwenny came, it was a little anticlimactic at first. She gasped and her tail jerked upright. Her pussy clenched down hard around his arm, and her hind legs trembled... And then she relaxed, panting a little bit.

That was it? Surely he could do better than that! So he started right up again as soon as her pussy relaxed around his arm, giving it to her even harder, twisting that little nub between his fingers.

Almost immediately, Gwenny came again. This time, when her pussy clenched around him, it pushed up harder from below, and a hot stream of milky-yellow marecum sprayed from her pussy – all over his favorite shirt!

But he wasn't about to stop now. This was getting fun! Again and again he drove her to orgasm. It was so easy! And he just loved the little wheezing moans she gave each time as her pussy squeezed and squeezed. He ran his other hand up and down her horsey ass cheek, and...

And she was soaking with sweat!

Finally, he stopped, actually taking a look at her instead of mindlessly driving on to her next orgasm. Her elven upper body dropped flat against the countertop in front of her, and the chestnut sides of her horsey body literally streamed with sweat. He could feel the heat rolling off of her, almost as much as he could feel it around his hand inside of her.

Okay. Maybe he'd overdone it a little.

Slowly and gingerly, he drew his hand out of her horsey pussy. He winced when the widest part of his hand had to stretch that ring just inside her entrance again, making her whine a bit.

When he finally got his hand out, it was soaked. With a silent apology to his – formerly – favorite shirt, he wiped his arm on it, promising to do his best to wash it later. Then he slowly walked over to the countertop where Gwenny's elven upper half was lying.

“Uh, Gwenny?” he said quietly, almost afraid to disturb her. “Are you ... okay?”

She popped up immediately, making her big breasts jiggle in a mesmerizing way. Then her eyes locked onto his. “I ... I need more!”

That was a side of her he'd never seen before! “More? I don't know if there's any more I can—”

“No! I can feel it!” She suddenly turned and grabbed his shoulders, shaking him a little. “It's like, like this thirst deep inside of me! There's something missing! The heat isn't going away yet!”

“Uh...”

She crossed the room in one galloping leap. “Yes! There's still enough left!”

Doug looked at the transformation potion ingredients in her hands ... which she quickly mixed together and poured into the chalice.

“Come on!” she said, holding the chalice out toward him. “Don't make me wait for it!”
