#5 of Changing Christy


(The following is a work of fiction, based off of multiple events and role-plays. This story includes transformation, bondage and anal sex.)

Christy laid on the couch, watching the television for the moment. She shifted as she watched, her mind actually on other matters for the most part. The canine that had taken her in was up to something. She was not entirely sure what it was just yet but it was something.

He had been acting slightly odd ever since the night she had been transformed into a cow. Not that she could say for certain, she had not known him that long and he never really talked about himself most of the time to her. He had seemed to be acting different though. There were times when we would bring packages home, but not let her know what. He also seemed to be watching her backside quite a bit.

Christy stretched out then stood up, shifting to keep her balance. One of the few things she did know, whatever was pending, she was going to have hooves. It had not been a constant matter, but he has been making her spend time with such, trying to get used to finding her sense of balance and walk with them. She figured that after hooves, high heels would be incredibly easy to do.

The hooves clopped on the floor some as she walked around, feeling the pulls on her calves, thighs, rear and even lower back. It felt like it would start to build and tone the muscles in her body. It was starting to get tiresome all the same. Whatever he had in mind, he damn well better do it soon.

There was a small coughing noise coming from behind her, causing the girl to jump slightly in surprise and turn to see the canine that had taken her in and started doing some unusual, though admittedly fun, experiments with her. Making physical changes to her body, then filling her sex or mouth with the shaft until he unleashes his fluids.

"Uhm...hi," Christy said in a sheepish voice, "I didn't see you there. I didn't know you were back already either. She shifted some, one hand pressing against her thigh as the other reached behind her, grabbing at where a tail would have been.

"From the way you're talking," he teased with a smirk, "I would think that I caught you doing something you weren't supposed to instead of just stretching out. Maybe if I had stayed quiet and watched you would have. Maybe play with yourself or something?" He raised an eyebrow some as he looked at her.

The girl shifted, her face turning red as she blushed at the thought. She was already naked, had stopped wearing clothes since she was turned into a cow. Her legs shifted, thighs pressing together as her sex started to get wet at the idea of playing with herself, more so with him watching her do it.

"S-s-so, what are we doing tonight?" She asked with nervous excitement. A part of her fought a little though. As much as she did, she did not want him to know that she not only enjoyed, but actually wanted more of what he had been doing to her.

"Same thing we do every night Pinky," the male said, trying to alter the sound of his voice. He shook his head some, laughing to himself at the look on confusion that crossed the girl's face.

"Some people have no sense for the classics," He teased her again. "In all seriousness though, you will find out tonight. I have been working and planning this for quite a while." He grinned and licked his lips, tail wagging excitedly.

The two went through the basic part of the night, dinner. They sat at the table, eating. Christy actually started to ask questions and catch herself actually telling about some of her own life before she ran away from home. The canine started to open up slightly as well. He did not give much, but some information of himself slipped out. Nothing of interest yet to pass between the two however.

Once the meal was over, the male canine stood up, stretched out and walked around some. He looked down at Christy with a smile and patted her shoulder.

"Well now," he said gently, "do you want to find out what I've been up to the last week and a half?" He leaned closed, muzzle almost touching her, then stood up and walked away, heading toward his room.

The girl's curiosity and excitement motivated her. She started toward where he went, the hooves clopping slightly audibly on the floor beneath her. She stopped as she reached the doorway, looking at it a moment. It looked as though she were taller then it, which she was.

She had gotten so used to the sensation, she was unaware that the male that had taken her in had started to transform her further. Christy's height grew to a total of seven feet. Her body swelled and thickened as muscles built up on her form, shoulders and hips growing wider. Short, thick hair started to grow up from the top of her hooves and down from around her hair line.

The canine watched with a smile as the changes took to affecting the human girl's body. He looked at the thick tone thighs and broad hips. The tongue flicked out, licking his lips as he thought of what her butt must look like now. His shaft swelled some in the sheath at the thought as well as his eyes going up to her breasts. What were normally a nice pair of c-cup breasts had grown in proportion to her size. He smiled some tail wagging.

Her own tail sprouting was what made Christy realize that she was changing already. The tailbone popped and shifted, turning around then growing a short length. The hairs for the tail grew longer, stopping as it reached the back of her knees. As her face started to push out, forming the snout, she looked around the room.

Not that it did her much good. The room was dark, dimly lit for the moment. She could make out the basic shapes of things, but could not entirely make out what they actually were, with the exception of the bed. The pointed and upright ears shifted, trying to pick up something for some reason. They shifted toward the canine, hearing him walk around in the shadowy room.

"Close your eyes Christy," the male voice came as he walked toward a large shadow. Christy shifted, then did as she was told to, making the canine smile.

He went to the closet and opened it, getting several items out. He approached the human girl turned into a mare, licking his lips. The canine walked around her once, taking in her thick toned body. He reached up and grabbed her rump, squeezing the cheek. He let out a satisfied noise at the feel and smiled as he watched her jump in surprise. He moved back to in front of her, starting to put the bridle around her equine head.

Christy felt the leather straps being put on her head, being adjusted to fit better. There was something that felt metallic against her lips and she opened her mouth, letting it slip past her teeth and into the back of her mouth. It was metal, but something had been coated to it, covering up the taste of the metal and giving it a sweet flavor instead. Something like syrup or jelly.

The male took a hold of her reins and gave a tug, watching her. He shifted as he watched her jerk forward from the tug in confusion, then started to follow his lead, tail wagging. He glanced down between her legs, looking at the hair around her pubic area and the wet nether lips, the canine shaft emerging from the sheath more. He stopped, bringing her to stand in front of a mirror.

"Okay, open your eyes," He commanded as he clicked the overhead light on. The formerly human girl did as she was told, seeing herself in all her naked equine glory in front of a full sized mirror. She chomped down at the bit as she looked at herself in a bridle, the reins just hanging down at her stomach for the moment. She shifted, noticing that to the left and right was blackness. She moved closer, seeing the blinders on the side of her head. Were she claustrophobic, it would have been scary. The mirror did give her some extra sight though.

The male moved behind her, his tail wagging. He reached out, gripping her butt. He stroked over the rump, across the hips, then up along the sides of her stomach and chest. He moved to her shoulders and squeezed, stroking down her arms to the hands where fingers ended in thick tapered hoof like tips. The male gripped the wrists and pulled them back behind her.

Christy gasped out in surprised. She turned her head to see what he was doing, but the blinders kept him hidden. Her thick legs shifted nervously, but she did not try to get away, despite the fact that she could have easily. In this form, she was actually stronger then he by quite a bit.

The canine smiled as she did not try to escape. He knew she was stronger, especially since it was his doing. He pulled her arms back behind them, then slipped the bondage sleeve up over her arms. He zipped it up, locking her arms together behind her back. He watched the large mare tug at them slightly, the reinforced vinyl holding them in place.

"Face forward," he said, letting his voice growl. Christy did as she was told, closing her eyes again as she felt nervous. Her jaw started to work unconsciously, chomping on the bit in her mouth. She felt him reaching up, putting something around her neck. She shifted again, feeling fear, curiosity and especially excitement. The sensation was odd as there was some adjustment made. Before she could open her eyes to see the new look, the reins were pulled on again.

The equine girl checked some. She could tilt her head up, but not down and she could not turn her neck left or right. She looked ahead, having little other choice. Her eyes locked onto what looked like a steel bar. It was a horizontal bar, supported on two vertical ones, set about four feet high. It looked like a newer version of the kind people used to...tie...horses...to... And she was currently a horse. A horse who had a bridle, bit, blinders, bondage sleeve and posture collar on.

The male felt her pause and looked at her. He gave a hard tug on the reins, catching her off guard so she was pulled forward and down some, making it so either she had to walk forward or fall. He smiled as she moved, leading her to the bar once more.

"Bend over," he said calmly. Christy did as she was told, bending down so her head was near the bar, her legs adjusting to support her weight and balance more in this position. She watched as he moved closer, his shaft coming into view, half erect and swelling up more. She chewed on her bit more, not sure what else to do for the moment. She felt a small tug and moved forward. The metal was cold as it pressed against her, the thick equine legs relaxing some as she let the bar take some of her weight.

The canine pushed the reins back behind her then patted her on the head with a smirk. He moved around, vanishing from sight as he moved behind her prone female form. He gripped her hip and stroked down, letting his fingers run over her rump once more before moving elsewhere. He grabbed a bottle of lubricant, shaking it slightly as he headed back toward her.

Christy shifted again, wondering what was going on somewhat. She adjusted herself to get comfortable, wishing the bar had some soft padding on it. She shivered slightly feeling his paw stroking up her sex then over the crack of her rump to the tail, stroking through the long thick horse hair. She shuddered, moaning out as she felt a finger start pushing into her female sex. She then tensed and gasped out in shock as some cold thick fluid suddenly poured onto the puckered ring of her backside.

The dominant male smiled to himself, the canine tail wagging. He pushed the finger in more, sinking his way deeper into the warm wet femhood. He gripped the bottle in his paw and reached down. A finger pressed against the ring of her tailhole. He started to rub, covering the ring in the lubricant, then started pushing forward to start sinking the tip of into her backside.

The submissive female tensed, clenching down on the fingers penetrating both of her openings. She closed her eyes, trying to relax and enjoy the feeling. This was something new to her. Her backside was virginal, no male having even touched it, much less penetrated it. The sensation of having the finger work into her rump was different to her. Not unpleasant, just something she had never felt before.

He smiled, tail wagging more. He squeezed the bottle of lubricant, applying more to the tight ring. He shifted, pulling back slightly then pushing forward to sink deeper into her rump still. The finger slipped out of the warm wetness of her feminine depths, slipping down slightly. The female juice covered finger slid down, pressing against her clit and starting to rub around the sensitive nub.

Christy snorted, then moaned out as pleasure jolted through her body. She pushed back, rocking her hips to try and grind herself against the finger more. The finger in her backside sank deeper, her body adjusting to the odd sensation of the penetration and starting to give her pleasure.

He watched her reaction, enjoying the excitement he was building up in her. The canine finger twists slightly, pulls back, then pushes forward, sinking his way deeper into her backside. He licked his lips, anxious to feel her backside around his length. He shook himself slightly, trying to keep himself in control so as not to do it too fast. He moved his other paw, sinking his thumb into her vaginal depths as he rubbed at the sensitive flesh between her thighs.

She moaned out, snorting through the massive nostrils. She wanted to beg for it, for his shaft, but the building pleasure made it hard to speak, and the bit in her mouth made it harder for her to talk. She shifted her body more, pushing back to pump against the fingers penetrating her body.

The canine licked his lips, the shaft twitching as it started to leak pre. He pulled his finger back, slipping from her backside some. He then applied more of the lubricant to her ring. He started pushing back in, working to sink a second finger into her depths, stretching her backside wider and getting her ready for his shaft.

Christy's body tensed and shuddered as she felt a mix of pain and pleasure coursing throughout her body. She was a little scared, but very excited and just could not wait for something to happen. Her body was building rapidly, her mind clouding as she wanted to be filled by him.

He grinned at her, watching her reaction. He pushed the fingers forward then pulled back, sliding his way from her sex and backside. The tube of lubricant in his paw was squeezed, the thick fluid pouring out onto his shaft. He dropped the container, giving his length a stroke, then shifted, pressing the tip against her tight little ring.

She moaned out, trying to keep herself from tensing up as she felt her backside start to spread as it was pushed open around the length that was working to sink into her body. She shifted her body more, biting on the bit as she both tried to push back against it to sink him deeper in pleasure, and pull away to keep him from entering her.

The male held still as he was partially inside her bodies, trying to keep from going any further for a moment to let her adjust to the sensation. He gripped her cheeks and squeezed, spreading them further. The eyes closed, head tilting back. The male hips started pushing forward, working to sink his way deeper into her ass.

Christy closed her eyes, feeling the slight pain and pleasure of her virgin pucker being spread open and taken by the male behind her. She gripped her hands, feeling the sleeve shift as the muscles flexed. Her tail flicked slightly, unable to move much. Her female sex was dripping wet, some of her juices flowing down along the inside of her thighs.

The canine sank in until he was halfway into her backside. He shifted, starting to pull back and slide out. The eyes closed, a growl of pleasure escaping his chest and muzzle as the hardened shaft pulled out, then started pushing forward once more to thrust into her and sink deeper into her bowels.

The equine girl gasped out around the bit in her mouth as she felt being thrust into again, hips slapping the cheeks as the knot hit the ring. Her body tensed, squeezing down on the length, trying to keep it in place and push it back out at the same time it seemed. It was a new sensation having herself filled like this, a mix of pain and pleasure.

He continued to move his body, pulling back then thrusting his way forward, sinking deeper into the tight pucker until the hips slapped against the cheeks, the knot pressing against the opening firmly. He grunts out and growls in pleasure, grinding the bulge against the tight ring.

Christy cried out as she felt the bulge smack against her opening, her body pushing back despite the sense of being stretch as she wanted inside her. She moaned out around the bit as the sensation of having her backside stretched got stronger.

The canine closed his eyes, trying to keep in control. His grip on her body tightened, the nails digging into the fur and skin as he fought the urge to speed up his thrusting, or just thrust hard once and sink the knot into her, tying them already. He tried to keep his pace, pressing his knot against her ring more firmly each time to stretch it a little more before pulling back.

The human turned horse girl shuddered, moaning, almost screaming out in pleasure. Her stomach clenched as waves of pleasure shot through her body. Fluids dripped down her thighs and onto the floor from her sex, making the puddle beneath her larger as she went through her orgasm.

The male gave one last long push, sinking back into her rear, and pushed the knot past the ring to tie with her backside. His hips pressed against the thick cheeks of the equine rump as he stopped, holding still with himself as deep into her as he could reach. His hips rocked slightly, grinding against the inner walls of her depths.

Christy moaned and shivered, feeling new sensations of pain and sexual pleasure then she had before. She rocked her hips back against his, clenching and unclenching as best she could as she moved to squeeze and stroke his length inside her, trying to get him to cum.

She did not have to work long. The canine finally reached his limit, releasing his fluid into her. The knot swelled, stretching the inside of her rump further. He clenched, snarling out as he unleashed the thick white fluid into her. With all the work and teasing to build up to this point, there was plenty of it filling her.

She shivered and shuddered, almost feeling like another orgasm went through her body. She snorted through the horse nose and chewed on the bit as she felt the thick warm fluid flooding her gut.

The two held still as the orgasm coursed then finally subsided, the two of them still tied together as the last of the fluid dripped into her bowels. He held still for a little longer, not moving. Christy shifted, trying to look back at him, despite the posture collar keeping her neck in place and the blinders. She felt him give her rump a playful swat, making her squirm slightly.

"Good girl Christy," he said softly, pleasure thickening his voice slightly, "We can take this off now." He stroked up her butt to and hips to her arms, starting to undo and remove the bondage sleeve, letting her arms go.

Christy reached around, stretching her shoulder and rubbing her arms. They ached from the blades in her back that were held still being pulled back to the fingers on each hand that had been pressed together. She did not feel anything when they were held in place, but now they burned and tingled.

He reached up further, taking off the posture collar as well as working to remove the bride and bit. As he worked the knot started to slowly deflate, easing the pressure on his male hood and the insider of her rear.

When all the equipment was pulled off, Christy took a hold of the bar in front of her, leaning on it for support as she waited for him to deflate the rest of the way. She tilted her head back and turned, looking up at her as she breathed heavily, smiling at him some.

"Very well done Christy," He grinned, tail wagging, "that was very nice and I enjoyed it, just like I can see you did too." He gave her legs a squeeze.

"Yes sir," She said happily, "I enjoyed it very much. I hope we can do it again sometime." She moved up, rocking her hips as she pressed herself against him.

"We will," He responded as he reached to stroke down along her stomach, "but not for a while. As for now, when we pull apart, we need to shower to clean up from this." He rubbed her toned body gently, feeling the hard muscles under the hair covering her.

Christy felt a small twinge of disappointment but did not argue with him. She wanted to some though. She enjoyed this and wanted to keep the feeling for a while. The equine girl shifted once more, feeling his hardness shift inside her backside.

The knot deflated further, then slowly pulled against the ring as he slid out of her. As he let her go, she went to the bathroom, shutting the door behind her as she got ready to clean up from her latest experience.
