Ben had his arms wrapped around my body and was lowering me rump-first into his lap. My tail _thumped_against his smooth chest - as much as I hated my new life, I couldn't deny the sensations that washed over my body every time the fourteen-year-old claimed me. He didn't make me suck him off anymore. Now that he had a soft, black-mailed fuck toy he took advantage at every opportunity. This morning, he woke me by grabbing me rudely from my sleep and pulling me into his computer chair with him.

My hind legs reached his thighs now, so I balanced tenuously there, whimpering at the now familiar feeling of his thick cock pressing up against my wet opening. More than three weeks had passed since my change, and I was still in heat. I became more and more convinced that my pussy lips would _never_shrink down and end the burning itch inside me.

Ben was the primary remedy for my trembling cunt. Sure, when he had time, he'd walk me to the railroad tracks and film me lifting my tail for every passing dog in the neighborhood, but those days became fewer and farther between, replaced by morning, afternoon and night beneath my former friend's warm body. I hiked my tail to the side, glancing over my shoulder as I lowered myself onto him.

He slid inside of me, making my voice quiver. Ben squeezed me tighter, clenching his eyes shut as he revelled in my tight pussy. Leaning forward, the heavy-set boy jabbed upward, spreading me wetly apart. I yelped, splaying my hind legs as best I could. His staff was long and firm, pinning my hindquarters in his lap. My eager spade massaged him, pulling him deeper before I lost myself in short, jabbing thrusts. Ben humped up into me in time, groaning noisily.

"Good girl."

He ran his hands up and down my belly, rubbing roughly against my teats. They seemed larger and more sore - I might still be in heat, but I knew enough about dog-breeding to recognize the first signs of pregnancy. The only question that remained in my mind was how many of them would belong to Pancakes, Beefstick, or Samson.Thank God they can't be Ben's - I don't know how I'd live with myself!

My whimpers turned to whines, which turned to howls. I slammed my hips up and down on his cock, tongue dangling from the side of my mouth. So good! I barked.

"Shush," Ben commanded, pulling me closer. I snapped my mouth shut, muffling my frantic moans. Ben didn't like it when I drew Sarah's attention, much less his own parents. The boy's sister still refused to believe that I would willingly subject myself to Ben, and she was absolutely right. But what could I do? He had pictures of my younger brother fucking a _dog!_Whatever Ben could do to me, he could do a hundred times worse to Zack with the press of a button.

Sarah got to walk me in the mornings, which I appreciated. However short, any break from Ben was a break worth having. The school week wasn't so bad, but the weekend was about to begin again and I knew that Ben probably had some new terror planned for me. And Zack? I could see it in the way Ben looked at me, whistling nonchalantly. I knew well enough that the evil in that boy wouldn't be quelled simply by my freely-offered cunt.

Ben slammed me down against his dick, poking me roughly against my innermost walls. My pussy split apart and squeezed up against his abdomen, hilted again and again by the horny teenager. I kept my mouth shut, even though Ben was groaning louder than I was. I let out a muffled whimper. It won't be long now...

"Oh, Slutpuppy!" he cried affectionately, wrapping his hands around my slender waist and pulling hard. "Beg for it!"

I knew what he wanted. Dropping my jaw, I began to whimper madly, fast and high-pitched, digging my paws into his legs to push down harder against him. I clenched hard around his cock, bucking my hips insistently. I glanced over my shoulder with my tongue dangling, whining at him.

"Okay, okay," he said smiling. "I'll give it to ya, you horny little bitch!" Holding me around the chest with one arm, Ben grabbed the base of my tail with the other, leaning forward until I was dangling out over the chair. He held me there half-suspended and hammered forward, groaning loudly as he came.

Splurt!

Ben was no dog. When he came, it was one and done, splashing me once or twice before he dissolved into weak shudders. Still, I drank him eagerly, my own rump spasming uncontrollably around his twitching cock. What Ben lacked in duration was made up for in size - his penis was thick throughout, with none of the tapering that my new species was designed for. His hard flesh had a lot more give, vibrating against the source of that inescapable, intense pleasure. Saving Zack or not, if Ben couldn't have made me cum, I don't think I could have put up with him for this long!

I rocked and roiled in the teenager's lap, howling softly through my tightly sealed lips. The itch was gone, at least for the moment, replaced by a warmth that spread less like a heater and more like an exploding grenade throughout my whole body. I flattened my ears, picking myself up and pushing myself down his trembling cock, knowing that I only had a few moments before the sensation was too much for Ben and he threw me off. I had to get what pleasure I could.

He lasted somewhat longer than normal, then pushed me off onto the floor, groaning. "That's enough," he commanded, shivering.

Still orgasming, I humped weakly against the air, feeling so empty. Curling up, I filled the void with my large, wet tongue, splaying my pussy apart in a desperate search for every drop of cum. The flavor was enough to egg me on, but the feel of my tongue pumping in and out of my cunt kept me cumming for several blissful moments before the moment passed and I was just normal old Derek again.

Just Derek, trapped in a body he was never meant for. Trapped at Ben's beck and call, with absolutely no hope for escape. My cheeks burned, realizing that the best part of my day - the moment I looked forward to - was when Ben ordered me to fuck him. It was Saturday morning, and I would spend it waiting desperately for the boy I hated more than anyone in the world to recover and fuck me again. When I whimpered again, it had nothing to do with my tongue in my heat-swollen mound.

"Good girl," he repeated, knowing that the false praise didn't get to me anymore. I could watch the gears moving in his head, until he settled upon, "I saw your brother yesterday, in the backyard. He was playing with Brian...Markley, I think? He seemed happy, moving on. Getting back to a normal life."

I glared at Ben, seeing right through him. The threat was clear enough, but Ben Hendricks was never a very subtle person. "You keep being such an obedient dog, and it'll stay that way."

I nodded slowly, pulling my tongue free with a wet_slorp!_ Ben smiled, took a deep breath, and said, "Damn, I gotta take a shower after that." He got up, grabbed a towel, and left the room, leaving me alone on the floor.

_What did I do to deserve this life?_Thinking like that was pointless - I'd done nothing. I was just the boy unlucky enough to fall in Ben's crosshairs. I'd thought that calling me a "dog-fucker" in front of the entire school was bad enough, but I had no idea the depths he would sink to when he had absolute power and no consequences. He was going to sink lower today, I just knew it. All I could do was hope that Ben's plans didn't involve Zack.

And that's when I saw it lying on the bed.

Ben's phone...!

He kept it close at all times, not wanting the phone to fall into his sister's hands. Sarah was actively looking for ways to sabotage her brother now - she'd said as much to Tinkerbell on their walks. If I could just bring this phone to Sarah, she'd have all the evidence she needs to convince her parents that Ben was abusing me - though not in the way she expects.

But she'd find evidence of Zack abusing me, too. That damned video! Blinking, I rushed over to the iPhone. Concentrating, I placed the very edge of my middle claw on the power button. It better be charged! To my relief, the phone sprang to life with a bright glow. Claws couldn't activate the touch screen, so I had to press my paw pads to the buttons, but with the large icons, it wasn't as hard as I expected.

Camera, to Video, to Recordings. There I saw it, all the evidence of my shame. There were over 50 videos now, mostly of me getting reamed by stray dogs in the yard. Most of those videos were online now, according to Ben. He even read me some of the digusting comments people left on his page. But two of the videos featured only me, Zack, and Ben. I shook my head sadly to see the still frame of Zack approaching me as Ben held me down on my back. I had to remember that my brother was drunk, and Ben had egged him on.

I could easily hear the shower running in the distance. I had plenty of time. Carefully selecting my brother's image, I tapped "delete". I tapped confirm, and thankfully, the phone didn't ask me for Ben's password. I panted in relief watching the phone think as it deleting the incriminating evidence forever. I sure hope Ben was too stupid to make any backups.

It's done. He can't control me anymore. I'll run to Sarah, and she'll protect me. I'll never have to suffer by Ben's hand or cock again. I'm free!

Adrenaline rushed through me, so excited I didn't even notice Ben entering the room behind me. He didn't have to take too long to piece together what had happened, 'his' dog dancing around the iPhone. But what did it matter? He couldn't hurt Zack anymore!

"GET AWAY FROM THAT!" he shrieked, shoving me aside and crouching next to the phone. "Bad dog!" Ben cradled the phone in his hands, quickly scanning the videos. Turning toward me with eyes burning, he said, "You deleted it!"

I backed up to the open door, knowing that Sarah was still in the house in case Ben got nasty. I didn't run - not yet - because if ever there was a time to gloat, it was now. The only thing Ben's videos could show now was that he was a huge pervert. I was done cooperating - cooperating is what got Zack into this mess in the first place! I gave the fourteen-year-old a toothy grin, wagging my tail.

Ben didn't chase me down. He didn't attack me. He didn't even scream at me.

What he _did_do made my tail and ears droop, and I felt a shiver straight to the bone.

He smiled.

* * * * *

That fucking bitch! I thought, trying my best not to show my shaking hands. I'd been so sure I'd turned Derek into my very own, submissive little cock-warmer that I'd slipped up and lost Zack's video. At least the other recordings were intact. I hadn't uploaded them yet, despite what I'd told Slutpuppy, but I sure as hell was going to_now_. Tinker_bitch_needed to be punished, and I needed some more leverage. How could she do this to me!?

I smiled at Tinkerbell, not willing to show my anger. She was a pretty cocky dog for someone with no cock! I walked over to the mini-fridge, still looking straight at the bitch, speaking softly and clearly. "I may not have that video anymore, but _Zack_doesn't know that. I think him and me'll take a little walk, whether he wants to or not." I emphasized my point by pulling the little bottle of Love Potion #10 from the false back of my fridge. There was still more than half a bottle.

The dog's eyes went wide. "Yes, I think it might be time for your brother to 'run away' from home."

I'll admit it, I was surprised by her reaction. The small German Shepherd charged me, baring her teeth. Now that's the kind of reaction I was looking for! Setting my legs, I closed my hands around her head, stepping aside to pin her against the bed. Reaching out to my nightstand, I grabbed something I never thought I'd have to use - a muzzle. Tinkerbell struggled as I held her mouth shut with one hand, wrapping the muzzle around her with the other.

She kept struggling, but it was useless. She couldn't even make enough noise to draw Sarah's attention now. Panting a little, I said, "Don't worry, I know just the place. And you can watch!"

She finally stopped struggle and just whimpered. I clipped the leash to her collar. "If you don't think I'll go through with it just because I can't control you without Zack, think again. I've got plenty of potion. I'm sure your mom really misses you - perhaps she'd like to be tied up at the train yard with you? Or maybe I'd keep her all to myself, to keep her dog cunt nice and tight."

That shut her up. Tinkerbell was trembling now, no less than she deserved for betraying me like this. I got dressed quickly enough, tucking my iPhone in my pocket before grabbing her leash. "Ready for walkies!?" I asked.

She followed me easily enough, not even trying to scrape off the muzzle. She knew when she was beaten. If she didn't obey, I could systematically destroy her whole family. Still, the thought of fucking Tinkerbell's mom right in front of her was pretty appealing. Maybe next weekend...?

I headed downstairs, grabbing the phone and dialing Zack. He picked up, sounding groggy. "Hey, Zack! I think you'd better meet me out back. If you know what's good for you."

Tinkerbell whined, but I pulled her along roughly, heading into the backyard.

Zack said, "Wha -"

"Outside - now!" I yelled, pressing "end call" with a flourish. I only had to wait in the chilly air for three minutes before Zack came tumbling out the back of his house, hair still a mess and in baggy clothes.

He couldn't see Tinkerbell at my side thanks to the large, wooden fence, but that was just as well. He raised an eyebrow at my smile. Might as well get right to the point: "You know last weekend when you came over?"

Zack gulped. "Uh...yeah?"

"Well, I had a certain...video recording on my phone that I've got sitting, ready to upload to Facebook. That is, unless I stop it in...3 hours or so. So I was thinking you and me and Tinkerbell might go for a little walk together."

Zack's mouth gaped open stupidly. I'd always thought the younger brother was smarter than the older - he certainly had more friends at school - but maybe I was wrong. "Get moving!"

The twelve-year-old blinked. "Okay, okay!" he said, following me as I opened the gate to the train tracks. He ran to catch up, while Tinkerbell looked up at her brother and whimpered. Zack asked, "You - you wouldn't really..."

I glanced at him, walking at a brisk pace. "I don't_want_ to, Zack, but I won't have to if you cooperate with me. Okay?"

"But...but you _told_me to! I was drunk, Ben, I didn't know what I was doing..."

I laughed. "Only _I_get to fuck Slutpuppy. But don't worry, I only want one, simple thing, and then I promise I'll delete that video forever, okay?"

Zack nodded, looking down at his transformed brother. "Why's she wearing a muzzle?"

I turned the corner, dragging Tinkerbell along beside me. Not far, now."She's been a bad girl. Now come on and hurry - the three hour clock is ticking!"

I jogged the rest of the distance, Zack easily keeping up. He was a lot more fit than his 'brother' used to be. Finally, there, along the railroad tracks - Zack's final destination. A three-railed wooden fence separated 15 enormous horses from the tracks. I used to come here when I was younger, an equine stud farm within walking distance. The summer was the best time, when all the mares went into heat. The breeders either didn't notice or mind that I was watching from the tracks. It was too cold now for most mares to be in season, but I had a little bottle in my pocket that said the stallions here were about to discover a tight and warm (if unwilling) piece of tail.

"What are we doing here?" Zack asked, still shaking.

Tinkerbell started to struggle again, knowing exactly_what I had in mind. I tied her leash around one of the fence posts. "_You are going to squeeze through that fence," I said simply.

"With that horse in there!?" Zack exclaimed, looking the creature over. A big, black stallion with a slightly warped diamond on his forehead; I knew him well. He was old now, but the breeders still brought him out to stud more than any other stallion. I think his name is "Blackie" but I called him "Reamer" on account of what he did to the mares they gave him. I couldn't have asked for a better, larger, stronger stud to introduce Zack to his new life.

"He won't hurt you. Get inside." Tinkerbell was trembling, frozen in place, knowing what she was about to watch. She's mine now; she'll never cross me again after this.

Zack thought over his options, but he really didn't have any. He couldn't know that Slutpuppy had deleted the video. How could he? The twelve-year-old cautiously slid through the top and middle rails, keeping an eye on Reamer. The stallion wasn't interested. Yet.

I took out the bottle. I hadn't bothered to mix the potion in with Gatorade this time, since he'd have_to drink it. The glass bottle was still more than half-way full. The label said, "Love Potion #10", but Zack would have no clue what it _really did. I offered it to the boy, saying, "Drink a gulp of this, then look at that horse or the _whole world_will know that you're a dogfucker."

Zack reached out to grab the bottle, miserable as a beaten dog, but it never reached his hands. The German Shepherd had too much give on her leash. She darted beneath the lowest railing, smashing straight into Zack's legs. "Hey!" the boy yelped, dropping the bottle of potion.

I watched in horror as the old bottle fell, as if time were slowing down. It spun two times in the air before landing in the mud and horse manure with a thud. My heart was racing. It didn't break!

Zack looked down in confusion, only for Tinkerbell to leap onto the bottle. The muzzle stopped her from grabbing it, but she placed her little paws on the bottle, growling up at Zack.

"What's going on with her?" Zack asked, quickly checking to make sure Reamer wasn't up to anything dangerous.

"Thinks it's a chew toy or something. Get it!" I yelled.

"She'll bite me!" Zack said, looking down at the bristling dog.

"She's got a muzzle on, idiot!"

Zack looked sheepish, but knelt down gingerly nonetheless. I underestimated Tinkerbell again, though. As the boy knelt, the dog spun the bottle, then pointed with a single claw at the label. Zack read it out loud, "Love Potion #10 - Madame Ruth's Magic Shop, 1135 Broa -"

"Just shut up and drink it!" I shouted. When Zack didn't make any moves, I knew I had to take matters into my own hands. I slid through the fence, ready to grab the bottle and stuff it down Zack's throat.

"Why? What is this all about? Why is Tinkerbell acting so strange?" Zack said, taking a big step backward, warily.

I kicked her hard in the ribs, making the seventy-pound shepherd _yelp_and cringe away.

"What are you doing!?" Zack yelled, agasp.

I grabbed the bottle, eyes flashing as I reached out to grab Zack by the collar of his shirt, pulling the smaller boy close. Popping the cork with my other hand, I said, "Drink this, you fucking queer."

I heard feet padding in the mud and glanced down to see Tinkerbell launching herself toward my legs, only to be _jerked_back like a rag doll when she reached the end of her leash. She couldn't save him now. Grinning at her, I turned back to Zack and -

Zack was spinning, lifting his arm in a wide circle until he wrapped his arm around mine. He kept turning until my grip on his collar couldn't hold anymore, and I let go against the pressure on my arm. He was still spinning, back turned to me, so I never saw his elbow coming until it _smacked_me in the side of the head. I staggered backward, desperately gripping the potion so I didn't drop it.

Cute move. I guess they actually taught something at those karate classes. I still had forty pounds on the little fucker, and I wouldn't underestimate him again. I stepped forward, arms up to protect my face. It might have worked, too, if I hadn't backed up into Tinkerbell's range. The German Shepherd grabbed my leg and pulled in a very undoglike way, pushing me off-balance. Spinning, I grabbed the nearby fence to slow my fall, but when I tried to stabilize my other foot, it slipped in the manure and I went falling down with my back to the fence, hitting my head against the fence post.

Everything seemed foggy for a few seconds, the pen a blur of brown and black. Was that Reamer? I lifted my right hand to see the bottle of potion, panting heavily. It hadn't spilled. Oh, thank God -

Zack was next to me, his hand under mine. Before I could react, he pushed the bottle to my lips, tipping it into my open mouth. I felt the cool gush of liquid on my tongue before I could pull it away. Sputtering, I spat out everything I could, tossing the bottle aside. Don't swallow, don't swallow!

"What did you do!?" I yelled, looking up. But it wasn't Zack I saw - it was Reamer, watching warily from the back of the stables. I shut my eyes tight.I didn't drink enough, and I didn't see anything, I thought to myself _I just have to get out of here and come up with another plan._I kept salivating, trying to wash my mouth out as I spat on the ground.

"I don't know what the hell is going on," Zack said, standing a few feet to my side. "or what you put in that drink, but I'm not_drinking it." The preteen's voice quavered, and he continued, "But you are _not_keeping Tinkerbell. You can't just _kick_a dog! I don't care what you do with that video; as far as I'm concerned, you can go _fuck yourself."

He still has no fucking clue. Even after all the strange shit 'Slutpuppy' has done, he still thinks she's just a dog. I'd laugh if I weren't trembling in fear. It is fear, isn't it?_Eyes clenched, I felt like throwing up right in the mud. _Was trembling how it started?

"Well...? What do you have to say for yourself?" Zack asked in a huff.

Nothing happened. I let out a huge gasp, starting to breathe again. Absentmindedly scratching my arm, I looked up at Zack, relief fading into anger. "You little mother-fucker!" I yelled, driving my fingernails into my arm. Why did it itch so badly? I glanced down only to see bright, white hairs growing out of my arm. Eyes wide, I said, "No, no, no, no, no! Not this...! This isn't happening!"

Zack could hardly understand the sudden change in tone, saying, "Wait, what?"

Sure enough, it was all over. I watched the hair - no,fur - spreading up my arm. I'd only tasted a few drops, and drunk even fewer, but that was enough. I'd been getting up, but I sank back to my knees, a dull ache in my stomach. I glanced over at Tinkerbell, who watched, seated in silence. She wasn't gloating - it was far worse. I wasn't imagining it, the look on the damned dog's face was pity.

"Fuck you," I said, staring straight at her. "This is all your fault, you know that?"

"What the hell is going on?" Zack cried, alarmed now as he watched my hands start to clam up, fingers visibly shifting.

I didn't fight it. I was turning into a horse and there was only one person who could save me. I spoke quickly, but my voice lasted long enough anyway. "Zack, please, you've got to help me. Go to Ruth's...the magic shop!" I yelled, mind rushing for the fewest words with the most effect. "On Broadway. Tell her to change me back!"

I didn't know if it was possible. The instructions had said the potion was permanent, but maybe with such a small dose... I didn't know whether Zack would even try. How soon before he realized what I was planning to do to him? How soon before he realized who Tinkerbell really was? I slumped down, knowing it was hopeless. I closed my eyes, waiting for the change to finish. There was nothing more to live for, the worst that could happen to me had already happened.

I don't deserve this!

Snort! The rich, deep grunt caught my attention. Looking over my shoulder, I saw Reamer and realized that the worst was yet to come! Like with Derek, the potion was changing me into the most appealing form for Reamer. What was I doing!? I had to get out of the pen, now!_On my hands and knees in the manure, I scrambled for the fence. I was _not about to let myself get stuck in the pen with that fucking monster!

Zack took a step back, watching me crawl pitifully through the mud. The idiot said, "What are you talking about!?" My hands were already shrinking and molding together into hooves, and my legs weren't far off. Combined with the sticky manure, I barely made any progress. The fence was just a few feet away, but it seemed like a mile.

I might have made it anyway except for another oversight on my part. I'd forgotten about my clothes! My chest began to expand and change shape, stretching my shirt into a wide bulge. The shirt was nothing compared to my blue jeans, though. The strong fabric creaked, holding in my thickening legs. My feet were getting wider, thicker and shorter, tearing holes in the seams of my shoes. Every part of me hurt!

"Oh, God, oh God!" I whined, reaching down with my hands to try to unbutton my pants. Not an easy feat when your fingers were curled into a fist and wouldn't open. I could see my fingertips merging with my palms, leaving me with big, useless clubs. I felt the fabric tear, my ass getting fat and wide. Desperately, I fumbled with my shirt, trying to kick off my shoes. I managed to toss the t-shirt over my head, but my misshapen feet were locked inside the bulging sneakers.

"Oh my God, Ben! What do I do? What do I do?" Zack gasped, watching the unbelievable. Tinkerbell watched quietly from behind the fence, knowing there was nothing any of us _could_do.

"Madam...Ruth!" I grunted, finally feeling my jaw begin to shift. My teeth were growing, my nose pushing forward. The change itself didn't hurt, but my jeans were like a special kind of torture. But the denim couldn't hold me back forever. My hips still had a lot of growing to do. I had to admit I was grateful when the pants finally ripped, rolling down my legs in tatters. There was almost nothing left of my underwear.

Now only my lower legs and feet were covered, so Zack could see everything that was happening to me. I tried to crawl forward, but the tight remains of my pants tripped up my back legs. My arms were growing thicker and longer, barely responding to my demand to flee. If there'd ever been any doubt about my transformation, it was now gone.

"You're turning into a horse!" Zack cried. Well thanks, Captain Fucking Obvious! My chest was growing in every direction into a thick, white barrel, but that wasn't what concerned me the most. I'd known it would happen from the moment I began to itch, but I still couldn't rip my eyes away. Trembling, I looked down my body to watch my growing legs, and what was happening between them.

"No-o-o-o!" I bleated, my throat constricting. There it was, my pride and joy, still sore from fucking Slutpuppy, but my fat cock wasn't growing. Why couldn't Reamer have been gay? Instead, I watched my dick shrinking. Zack was watching too, jaw dropped. I shrank away like I was dipping in cold water, but it kept going. At the same time, my balls pulled up and out of sight, and two soft mounds began to sprout from my abs. I yelled again, but my stretching snout only let me whinny.

"Hey, help! Help! Someone!" Zack called, looking around. But it was Saturday, and no one worked at the yard. What could they do, anyway? I reached down with a glossy, black hoof to poke mournfully between my now empty legs. While my rump grew in all directions, I felt the remnants of my cock splitting apart, something stirring deep inside me. I was halfway there, now, almost a filly.

Now Reamer was interested. I heard heavy footfalls in the mud behind me, the stallion knickering as he watched my changing hindquarters. While one shaft fell away, and another sprouted just above that. A thick nub of flesh poked out from my spine, brilliant white hair spilling off of it into a long, wiry tail. I glanced over my shoulder, trembling. I knew that look from many years of watching Reamer do his work. He was hungry, and I was his meal ticket.

I have to get out of here!_Shivering, I leaped forward toward the fence, tripping on my torn jeans and falling face first in the mud. I must have fucking looked like an Almond Joy, my fat, white body covered in brown horse shit._Mounds, I corrected myself. I didn't have any nuts.

My shoulders had shifted, locking together so that I could only move my arms forward and back. My elbow was swollen and white, and I struggled to stand uselessly. How do horses get up? I kicked and kicked, squirming in the mud, until _finally_my jeans came off. My shoes were torn apart nearby, leaving me completely naked. I might have been cold, except for the thick layer of pure-white fur even now spreading up my neck.

My neck itself_was spreading! As if crawling forward wasn't hard enough, I felt my neck thicken and _stretch, curving as it lengthened. For a moment, it appeared as though the fence was getting closer, and my heart leapt - but it was just my head and face growing outward, eyes pushing further apart. Straining, I looked down, trying to gasp when I saw that my barrel was too thick to go through the fence slats now. The only sound that came out was a snort.

Zack watched, frozen. I guess I couldn't blame him - I wouldn't have left until the show was over, either.

The gate was tied shut with a heavy, metal lock. There was only one way out now - over. How could I think to jump the five foot fence when I couldn't even _stand?_Still, I had to try. If I stayed in the pen with Reamer, he _would_have me. I'd seen personally how he treated fillies that fought him. Gritting my thick, white teeth, I concentrated on the first step.

Squirming forward, I planted my front hooves on the ground. My shifting hind legs were stretched out awkwardly, so they'd be of no use. Struggling with my new muscles, tried to push myself up with just two legs. My elbows wobbled, but my front half was too heavy for that, and still getting heavier. All remnants of my humanity were gone now - all that was left was growing into my new body. I must have been three-fourth's full-size now, like a pony compared to Reamer, who was a full-sized thoroughbred.

Like a lightning bolt, I suddenly remembered how horses get up. Was my _brain_transforming too? I didn't question the newfound memory any further, I just sprung into action, rolling over onto my right side. As quickly as I could, I whinnied and tucked my back legs to the side, swivelling my upper body back into an upright position. _Now_I could do it. Tossing my front hooves out in front of me, I tensed my muscles, pushing upward just as hard as before...

But _this_time, my back legs were ready. With a leap, I got my left leg beneath me, wobbling as I pushed with all three limbs. For a moment, I seemed set to topple over, but I finally found my fourth foot. I was up! I whinnied triumphantly.

"My God, Ben...Ben, you're a horse."

I gave the twelve-year-old a look, though I don't know if he could recognize a cross quarter horse. The transformation was complete, and one way or another, probably permanent. I was significantly shorter than Reamer, almost a foot at the shoulders, and my pure white fur might have been beautiful if my belly and right flank weren't caked in manure. I'd always suspected that the stallion took a certain pleasure in ramming his cock into the tight little snatches of small fillies; now, as his ideal mate, I _knew_it.

"Are...are you still in there?" Zack asked like a moron.

I wanted to kick the bratty little bastard, but I didn't have enough time. Instead, I tossed my head up and down. But I had a fence to jump, and I could hear Reamer's heavy footsteps approaching from across the pen. Tossing my head, I tested my legs. I built up a pretty good speed, though I stumbled a bit at the canter. How do horses remember all these different ways to run?

Knowing Reamer was coming for me, I ran with my right flank to the edge of the pen, running in a wide circle. Sure enough, I could see the large, black thoroughbred trotting toward me. Snorting, I picked up the pace, giving the horse a wide berth.

In fact, I could see both him and the wall at the same time, but I couldn't see anything in front of me without tilting my head. I got dizzy looking through my wide spaced eyes, but I knew I only had one chance at the jump - Reamer wouldn't give me distance for long - and I could already smell the sharp scent that I knew must be wafting out of my cunt.

I sprinted past Reamer, rounding about to face the five foot fence. Tilting my head to watch both the stallion and the fence at the same time, I kicked my hind legs off the muddy ground, and pounded forward. I felt confident in my feet - I could get the speed to clear the bar, but could I get the height?

Zack backed up, realizing now what I was doing. He gasped, "Ben, wait, no! You'll never make it! Just stay there - I'll find Madam Ruth and bring her here!"

The little fag had no idea what fate awaited me if I stayed here. I ran faster.

"You'll get yourself killed!" the boy exclaimed, stepping out of the muddy pen through the gate.

Would that be so bad? I pictured it, leaping but not clearing the fence, my heavy body crashing into the metal posts. My legs would shatter for sure and maybe my back. Still, I don't think Reamer would manage to fuck my dying corpse, so it wouldn't be all bad. I was galloping now, and the fence would be there in just a few seconds. I tensed my legs to jump, bracing myself for the sickening impact...

My front hooves dug into the dirt, followed shortly by the back two. I balked, skidding as I turned to the side, smashing sideways into the fence. _No, no, no, no!_I was supposed to jump! That was my only chance! My ribs stung from the impact, but my legs were spared the brunt. Trembling, I turned to face Reamer, who grunted and flicked his tail. I swear I could tell that the horse was annoyed at my escape attempt, and I knew exactly how he'd get back at me for that!

I could try to build up speed and jump one of the other walls to the enclosure, but that would just put me in a pen with one of the other studs on the farm. Maybe if I kept my rump up against the fence until Zack got that scatter-brained witch bitch? I'd seen frightened mares try that before with no success, but I only needed to last ten minutes, and there weren't any men leading me around with a rope. I faced the stallion, flattening my ears, and raising my thick, upper lip to show my menacing teeth. He just snorted, unafraid.

"You're a girl!?" Zack cried, standing just behind me on the other side of the fence.

I jumped forward, suddenly realizing that with my ass pressed up against the fence, the perverted dog-fucker would have a perfect, unimpeded view of my newfound pussy. I couldn't see it for myself, but I'd seen enough horse-cunt to know what it must look like - a pink, swollen tear-drop, with a touch of deeper red peeking through the thick lips, squeezing closed only to open again to release another acrid puff of musk.

How long before he realizes the full extent of my plans for him? He was meant to be the horse, he was meant to be the filly, _he_was meant to service Reamer? Why wouldn't he just go and get the witch!? I'd be sore-pressed to hold the massive stallion off even if the boy left right now, but at this rate, I didn't expect him to remember he needed to get help until after Reamer was on my back!

The black thoroughbred didn't waste any time! No sooner had I stepped away from the fence than Reamer had swooped in alongside me, curling his head around behind. I should have stayed back and ignored Zack, but it was too late now, with the stallion's body pressing against mine. His neck muscles alone were enough to keep me from pushing him away.

Worse, he'd tucked his head below my tail for a_reason_. Before I could even whinny in protest, Reamer had nuzzled his way in, pressing his fleshy lips up against mine, and plunged_his tongue inside me. I didn't like it - how could I? - but I dropped my jaw and _neighed, tail launching straight up. I was only a foot from the fence, Zack and Tinkerbell could see everything from the other side.

Every nerve trembled as I felt him sliiiiide_his thick, wet tongue inside my cunt, warm breath washing over my thick, black pucker. _Schlurp!_rang out when he drew his tongue up, tugging and pulling my pussy lips, saliva slickening the dark pink tunnel. More than drool stained my hole though. Grunting, I tensed my cunt, gushing juices onto his tongue. Reamer pushed his jaw forward, up between my folds, teeth grating against me as he began to _gulp, drinking it all up.

I knew I should just run forward and find another wall to hide in front of, and I sure as hell wasn't a faggot like the two dumbasses watching in silent shock, but I couldn't move. I felt like my four hooves were rooted to the wet ground. The best I could do was lower my tail, the coarse hair flopping into Reamer's eyes.

I should have known better. Reamer didn't take kindly to resistance. Snorting loudly, he lowered his snout and clamped his flat teeth down onto my fat, white ass. It _hurt!_I hopped forward, letting out a sound that was half whinny, half whimper, looking over my shoulder at the big stallion.

I'd been trying not to look at him, but now I couldn't look away. His huge, muscular body I knew well from years of watching him work, but never from this perspective. This time those dark, insistent eyes were on_me_, and the thick, pink and black cock swinging beneath his stomach was meant for me. I watched the thick organ sway, taking in all the veins and ridges. Reamer tossed his head and flagged his tail, and I lost control of my body.

Lifting my tail, I spread my legs and relaxed my body, only realizing too late what I was about to do. A cascade of yellow piss drained out of me into a puddle on the ground. I watched Reamer, frozen, as he lowered his snout to the growing pool, lifted his upper lip, and then whinnied into the chilly air. I flatted my ears, recognizing that sound. He was ready.

I might have stayed frozen there like a retard if Zack hadn't brought me back to reality. He said, "Holy shit, Ben!"

I shook my head clear and jumped forward, but Reamer was bigger and faster. I only made it three steps before the black horse had not only caught up to me, but launched himself onto my back. I squealed as his enormous weight landed on my rump, making my hind legs buckle. I barely managed to keep my footing, though perhaps it would have been better to fall into the mud.

It was over, and I knew it. I was his, but I wasn't about to go down easy. I bucked and kicked, neighing frantically in my effort to dislodge him. Reamer dug his sharp hooves into my hips, easily hanging on while I tired myself out. He could have just waited for a minute, but he was in a hurry. Pulling himself forward, he drew his strong, flat teeth to the back of my neck, clenching down around my white mane and sensitive neck. Tugging back, he forced my head up until I was squealing into the air, unable to move beneath him. That was all he needed from me.

I heard the faint _slapping_of his cock against his belly as he lifting it, humping forward every few seconds to test his aim. Reamer was an old hand by now - I braced myself, knowing that the blow would come, and come soon. At least I'd lost my virginity in Tinkerbell! I couldn't have lived with myself if, like Derek, my first time had been as a whimpering bitch. Shivering, I spread my legs, biting my lip.

Sure enough, only _now_did Zack process what was going on. I watched with one eye over my shoulder as the boy stood transfixed by Reamer's thick cock flapping up and down, getting closer and closer to my unprotected cunt. His eyes widened and he said, "I've got to get help!"

Too late for me, I knew. But it didn't even get that far; before the boy took two steps, Slutpuppy reached over and grabbed Zack's white pants awkwardly with her paws. He looked down at the dog and exclaimed, "Tinkerbell!?" as confused as ever. I thought maybe I'd lucked out, and the boy was just a complete moron, but then I heard the words that sealed my fate. "No, no, you're_Derek_, aren't you!?"

She nodded, letting go of his pant leg, before looking straight at me with cold, dead eyes. The message was clear - she wanted to watch. Zack said, "Oh my God," as the full realization took effect: I'd changed his brother into a horny cockslut, bred her to every dog in the neighborhood, and then fucked her myself, right in front of Zack. Bad enough, but then I'd enticed Zack to do it too. Now the boy knew. Now he realized what I meant to do to him with the potion. He stood beside his former brother, both queers watching to see me get reamed.

I only felt Reamer's tip against my quivering pussy for a tenth of a second before it happened. Grunting, he tugged back with his teeth and launched himself forward, ramming straight into me like a freight train. My undersized cunt _ripped_open against his onslaught, and I thought my huge rump would tear in two! Arching my neck, I let loose a high-pitched, helpless squeal, legs buckling as more and more of his weight shifted forward, onto my back.

Behind, at their angle, the two siblings could see how much my pussy had to bulge to fit Reamer's giant sausage. I swear, by the time his skidding to a stop inside me, he was spreading me half a foot. My eyes shot open when I felt Reamer's heavy balls smack against my butt, every inch of my tight, filly cunt trembling full. How could he possibly fit!? His fleshy tip poked and massaged the entrance to my womb, apparently _exactly_the right size to claim me completely.

Reamer let go with his teeth, whinnying loudly in my ear as he leaned forward, dug his front hooves into my thighs, and pulled back a foot or two. Just enough to slam forward again, forcing my slick hole to engulf him again. The force of his thrust picked my back legs all the way off the ground, wobbling when I finally landed back in the manure. I bugled pitifully into the air - it hurt, yes, but there was so much more. I wanted_him. My pussy strained and squeezed around his giant dick. I even dug my front hooves into the mud and pushed _back, rocking my hips up and down. Heat rushed to my face, but I didn't care - I was nothing more than a cumbucket to the thoroughbred, a vagina at a convenient height, and for the moment, that was okay by me.

I even forgot about my audience, biting my lip and moaning into the crisp air. The only thing that existed was Reamer's throbbing, pink-and-black cock pumping back and forth into my battered cunt. Ears flat and jaw dangling open, I squealed again, bucking beneath Reamer just to feel his swollen shaft shift inside me. I could hear and feel the thick, slimy pre-cum gushing out into my vagina, but that only made the pain dull, replaced by a slippery warmth. I'd watched Reamer at work dozens of times, but I'd always pictured myself as him, not as his whinnying conquests.

He bit down on my neck again, straining humps speeding up. I suddenly felt the pressure building inside of me, Reamer's tail flagging as his cocktip flared, swelling up against my last line of defenses. My fertile womb was nestled up against the barrel of his gun, and I knew for a fact he wasn't shooting blanks. Could I really get pregnant? Slutpuppy had fucked two dozen dogs at least, but it was too early to tell if any of them had taken. Reamer slammed forward, hilting himself inside of me so that his thick, black balls quivered against my teats. One thing was certain - if I_could_ get knocked up, I was definitely going to.

Letting go of my neck one last time, Reamer tossed his head in the air and neighed, signaling his total domination of me. I joined him, my piercing whinny echoing throughout the empty stables. Flagging his tail, his hole pressed firmly against the tight opening to my egg chamber, Reamer let loose. A thick jet of thick, greasy cum shot straight into my womb, every quivering pulse of his balls signaling another sticky load. I dissolved into a whimpering bitch around him, just like Tinkerbell had for Pancakes and Beefstick, bucking and squeezing and moaning every second I was bred. My legs trembled at the glug, glug of Reamer's firehose trying to put out the fire in my uterus, heavy cream splattering my insides before settling wetly in the bottom of my belly. My eyes rolled back in my head, and I knew for a fact that this was it - I was coming away from this with a foal...or two!

Zack and Tinkerbell watched quietly as the next, grunting rush of cum backwashed out of my full cunt, spraying Reamer's thighs. That was it, I was completely bulging and bloated with horse cum. Zack just shook as head as if to say, "How could you?" He would never help me out of this situation now. I was going to be a filly forever - _Reamer's_filly. I shivered, realizing I had better get used to being brimming with cum. Tinkerbell was still in heat almost a week after she should have cooled down; I would be in season as permanently as I would be a mare. And Reamer wasn't the kind of stallion to leave a filly wanting.

I was still moaning, chest heaving for air, when Reamer finally backed off of me, slippery cum dragged out by his flared tip. Cum gushed down my hips like a waterfall, leaving no doubt as to what transpired. I kept my tail in the air, not wanting it to get stained and matted in cum. Sure, that meant that Zack and Tinkerbell could see every last drop bubbling out of me, but what did it matter? Covered in mud, shit, and cum, I had no dignity left.

Reamer just left me quivering there, walking over to his hay-trough to eat as if nothing had just happened. I'd been fucked by a horse, and if I couldn't manage to jump out of here, it would happen again and again. The farm employees wouldn't be back in full number until Monday. What would they do when they saw me in here? I could only hope that they transfer me somewhere else. Most likely they'd be puzzled, but wouldn't look a gift filly in the cunt. They were in the business of breeding horses, and as far as I could tell, I was perfectly made for that!

How many times would I be panting underneath Reamer in the next two days? Turned out to be a moot question. I barely moved two feet before I heard a loud THWHUMP!_All eyes turned to the newcomer, a draft horse who'd managed to jump the neighboring fence. I knew him, of course. I'd always called the shaggy brown stallion The Beast. Whinnying, I shied away from him, looking to Reamer. Stallions weren't known to share, but the thoroughbred knew better than to pick a fight with The Beast. The draft horse was a foot taller than _Reamer, and his cock was already as big and still swelling.

I was in for a long,hard weekend...
