Sarah brought a large box into an empty space in the living room. The box measured bigger than she was. She had ordered some workout equipment, and it had finally arrived. The brown haired fair skinned girl had to pull the box into her small living room. She opened up the box, and noticed a small box inside, as well as various pieces of workout equipment, weights, a mat, and various other small things. There was no large equipment, but that was because Sarah couldn't afford such giant things.

Sarah opened up the box, and she noticed a DVD of various muscular anthros working out. She had seen the picture when she ordered it online, and thought it was weird that the show would have anthros, something that didn't even exist, but she just ignored it. The reviews from the workout equipment were fantastic, but it was noted that in order to get the best results, one had to work out with the DVD while drinking the protein drink when the DVD instructed the person to do so.



Sarah wore a gray shirt with shorts and socks. She kept it fairly simple to do her workout. She didn't have any actual workout clothes per say, but she thought that those clothes were a little silly anyways.



Sarah popped in the DVD, and watched it start up. What she saw made her eyes widen as the DVD began to play the workout video. It was an anthro horse, a genuine live anthro horse, at least one that looked real. She wore a black yoga top, and black yoga pants with green stripes on the sides. Behind her were all sorts of other anthro creatures. Sarah could make out a hippo, a rhino, a surprisingly muscular pig, various fit creatures, all of whom stood in the background, with that brown furred horse up front.



"Hello viewer. In this video, we will be doing some basic exercises to help warm you up for the real tough workouts. This includes a brief five minute workout, followed by five minutes of rest, and then another five, and so on. We'll do this for half an hour, and then we'll move onto some of the harder things. Let's start with some stretches." The horse spoke, her mouth moved in a manner that definitely did not look fake.



Sarah was amazed with the horse's movements. The way the horse spoke, the way she stretched back and forth with her upper body. Sarah wanted to dismiss it as computer graphics, but if it were just graphics, then they were very realistic, and they timed it so well with the voice.



"Are you just going to watch me, or are you going to join in?" The horse said with a brief pause, before she started again. As she stretched, so did the various other anthros behind her. With her legs up straight, she bent her upper body to the left, and then to the right.



Sarah jumped a bit in surprise. She definitely didn't expect the horse to say THAT. Sure, maybe some generic workouts would say words of encouragement, but never asking if the person wasn't working out with them. "Oh, of course." She said, jokingly to the screen. She posed her arms up into the air, and stretched her body, just as the horse did on television. She could hear soothing music coming from the television, and it just made her smile. Workout videos could sometimes be so corny, especially with the music, and this definitely felt like the case with this DVD.



"There you go!" The horse said with a smile as she stretched her arms left and right. After a moment, she put her hands on her hips, and slowly raised up her legs one at a time. It looked almost as if the horse was marching, but in slow motion. "With that torso all stretched, it's time to get the blood pumping in those legs." Each time she lowered her leg, a soft 'clop' could be heard from the hooves the horse had.



Sarah smiled faintly when the horse commented on how she started exercising with her. She felt a little silly, but it was just a casual workout in her home, with nobody watching her. She performed the various stretches that the horse did in unison, focused on the beats from the television, but unable to take her eyes off of the various anthro creatures behind the horse. She noticed many of them had female shapes, and she was amazed at how lifelike they all were. For a DVD that looked cheesy and had poor quality sound, it also looked as if those anthros actually were real.



"You're doing great." The anthro horse spoke up. After about five minutes of stretching, the horse walked away from the group, and over to a counter with what looked like chocolate milk. "Now, take a short breather, and make yourself some protein mix. Just pour it into your favorite drink. It's flavorless and odorless, so you can mix it into anything!" The horse took a drink of that milk. "Just pause the video, take a drink, and then come back when you're ready. We'll get to the true workout afterwards!"



Sarah rolled her eyes, and hit the pause button on her remote. "Let me guess, you're going to be one of THOSE videos. I buy another DVD for part two, and then more protein mix. The pattern repeats, and you guys make out with a ton of money." Sarah grabbed the protein mix, as well as a cold bottle of water from her fridge in the kitchen. 

The protein mix was about as large as the bottled water, and according to the instructions, it just said one teaspoon. Sarah followed the directions. She put the mix into the water, mixed it up, and drank it. It was just as the video described, flavorless.



Sarah walked back into the living room, and pointed the remote at the television. "Now, if I don't see any big huge noticeable differences, I'm not ordering any more of that mix." She jokingly spoke to the television before she hit the play button.



"Alright, now that you've got some of that mix in your system, it's time to really get into the exercising. We'll start with some simple pushups." The horse walked back to the scene with the rest of the anthros. Each of them suddenly jumped up in the air, and bent their bodies downward. They caught themselves on their hands, and lowered their body to the ground in the pushup position. "Don't try this at home." The horse then said, with a wink to the camera.



"Yeah, I'd sprain something if I lowered myself like that." Sarah said to herself with a chuckle. She got onto her knees, and lowered herself to the floor. She put her hands on the ground, and elbows in the air. "Ready when you are, miss horsey."



As if the horse heard her, the equine nodded, and then pushed herself up. "Okay. We'll start slow. One..." she lowered herself back down, then after a brief moment, she got back up. "Two." And she repeated that pattern.



"I thought you said intense workout." Sarah chuckled as she pushed herself up, and did the workout with the video as close as she was able to match her. "A few pushups every second doesn't seem very intense to me." She had to admit, the video had a unique vibe to it. The video responded to her, and she responded back to it. Sure, when she talked to the video, it was jokingly, but it almost seemed as if the video responded to what she said and did.



The horse's ears flickered. "Oh, we're going to get more intense." The equine said, again, as if she heard what Sarah said. She continued the exercise of pushups, but as she did, she slowly increased the pace. It was first one pushup every five seconds, then one every three, then two, and then finally one pushup per second.



Sarah continued to do her workout with the horse. She fell silent as the horse increased her pace gradually. Sarah wasn't one to work out very much. She had tried to do it on her own, but when she tried pushups by herself, she often got tired after a good ten. As she worked out to the workout video though, she pushed herself past ten. With each push, the next push felt surprisingly easier than the last. She kept her eyes on the horse, unaware that her arms were growing and bulking up in size. Sarah first had fairly normal arms, with little muscle mass. After the first ten, a slight bulge in her shoulders showed. Another ten reps, and her arms looked toned. Every pushup was another half-inch in growth, and every pushup Sarah felt more energy to keep going as sweat slowly formed on her.



The five minutes of pushups felt almost like an eternity. Eventually, the horse got to another ten reps, and once she did, she paused, and stood back up. "Okay. That was a nice five minutes. Take some time to relax, get more of your drink, and we'll get right back to work!"



Sarah let out a small sigh as the exercise was finished. She felt herself sweat, but at the same time, she still felt so energized. She thought to herself that maybe the protein mix had caffeine in it. She took the moment to look down at her arms, and her eyes widened. Her hairless arms were muscular. They weren't hyper in size, but they were definitely the size of what a bodybuilder might have. "W-what..." She raised one arm in disbelief, and felt the bumps on the other arm. They looked real, they felt real, and when she flexed, she saw those muscles and veins bulge. "What happened to me?" she could feel her heart begin to pound with worry. There was no way that this was normal to gain this much muscle this quickly.



"Hey now, what's the fuss?" The equine asked towards the camera, as if she heard Sarah directly. "If you're not panicking, then I can tell you didn't have any of that protein mix. If you ARE worried, then allow me to reassure you. Those muscles on your arms are definitely real. They won't stick if you don't keep exercising though, so keep on going, and you'll keep on growing!"



Sarah looked at the video with wide eyes, and then back at her arms. "At least you're not talking directly to me that time." She mumbled. She stared at the muscles on her arms, and poked them again. They were firm and powerful, they were definitely muscles, and they were hers. She was tempted to stop the video then and there and go see a doctor, but at the same time, the idea of becoming muscular was tempting. "Maybe just...one more exercise." She told herself. She took a swig of her drink with the protein mix, and then stood in the living room to wait for the next set of instructions. Sarah definitely found the muscles scary, but they weren't freakishly huge. They made her look powerful, and they weren't big enough to rip her clothes. "I'm trusting you on this, horse." She said to the video after she took a deep breath.



The equine grinned. "Good girl! Alright, squat time." Various crewmen suddenly appeared behind her, and the various other anthros, and set up what looked like a Styrofoam wall behind each of them. The equine, and the other anthros, placed their backs up against the walls, and performed a squat. "Just like us, work those leg muscles!"



Sarah wasn't sure if it had been five minutes yet, but she went to her white wall, turned to the video, and performed the squats as the video instructed. During the first two, she paused briefly. "Wait...good...girl?" she raised a brow at the television. It was definitely bizarre. Sometimes it behaved as if it watched her, other times it just acted like a normal workout video. She shook her head, and rolled her eyes, and just did the squats. Whether the video watched her or not, she had to admit that it gave some impressive results to her body.



"Watch your legs while you work out, see the results for yourself." The equine said with a grin. "You don't get these kinds of muscles by drinking protein mix and sitting around, you have to get that butt of yours up and work out! The muscles you work out will get bigger the more you work them out. Become the next mister or miss universe, drop jaws at a gym, get a toned body, or just lose some weight, this exercise with this protein mix is guaranteed to make you lose fat, and gain muscle!"



Sarah did just as the equine instructed. She spread her legs a bit to get a better look at her legs as she moved her body up and down. The changes were difficult to see at first, but after the first ten reps, she could see some muscles on her legs form. The muscles were little, but after every few sets of squats Sarah did, she watched the muscles grow and spread throughout her legs bit by bit. From her thighs, down to her legs, she went from slightly flabby, to toned, to slowly getting to the bodybuilder legs. She couldn't see her feet with her shoes, but she could only imagine them getting as muscular. "This is amazing." She said quietly. A workout video that had instant results, it was impressive. She would have to work out occasionally to keep the muscles of course, but it was worth it. "I wouldn't have believed it, if I didn't see it."



"We only do these exercises enough to get you as big as a bodybuilder, but by all means, if you're in the hyper crowd, keep on going, and keep on growing." The equine encouraged with a grin as she continued the exercise. Loud beats that sounded like a dance floor beat in the background. "Just pause the video so you don't lose track of where you are and to keep you evenly built, unless you want to be hyper in only one area!" she added.



"I wonder if this works for men and masturbating, or me and squeezing my chest." She said, although jokingly. She wasn't sure if she would expect a response from the video. Sometimes it did, other times it didn't.



"And I can tell what you're thinking as you watch those muscles grow. The growth only works in areas that have muscles that CAN grow, unless you do some extra special exercises." The horse winked at the camera before she continued doing her squats for another few minutes. The exercise ended a few minutes later. "Now, give yourself five minutes, and then we'll work on that chest!"



Sarah was only half surprised when the video responded to her. She figured that maybe she was just an average person, and this show responded to the average person's thoughts. "Are there muscles in the cocks, balls, and tits? Wait..." the horse mentioned special exercises. Sarah had to wonder what that meant. She recalled the video had 'bonus features' at the end, and she assumed that it was some sort of behind the scenes to explain how the anthros in the video were as realistic as they were.



"Okay!" The equine shouted. "Five minutes are up. Now it's time to get onto that bench behind you, and lift some weights. Like before, your muscles will grow the more you work out. In this particular case though, the weights on the barbell will also grow when you work out, gradually increasing with the more muscle you get on your chest. Feel free to take off your shirt for this one to watch yourself get large and powerful!"



Sarah raised a brow when she heard the video mention a bench. "A bench, like, a workout bench? I don't even have..." she paused as she turned around, and saw a workout bench just positioned right behind her. Sarah KNEW she didn't have any workout equipment like that, and while it was true that the video came with some equipment, it definitely did not come with a workout bench. Even if it had, it wouldn't have been set up behind her back. "Okay, seriously, what is going on?" she looked at the video, and then back at the bench. She wasn't going to complain about the muscle growth, who would have? She had the legs and arms of a bodybuilder. To have workout equipment suddenly appear in her room was definitely weird, and almost scary.



"This video provides you ALL of the equipment you need to grow big and strong. Hop on that bench, and start lifting with me!" The equine said happily. She moved to her own bench that just sort of suddenly appeared next to her in the video as well, and the other anthros followed to their own benches. Each of them laid down on their bench, and then waited. "Just waiting on you newbie!"



Sarah slowly walked over to the bench, and she felt the black padding on top. It felt real, and as she inspected the weights, she noticed it was 20 pounds each. She still couldn't believe it, but she shook her head, and laid down on the bench. "Just don't get any weirder on me." She said quietly. She grabbed onto the bar, and waited.



"Good, now begin!" in the DVD, the horse took the weights, and lifted them up and down. She went at a fairly slow pace. The weights on her barbell simply couldn't be read, but the sizes were much larger than what Sarah had.



Sarah watched the horse lift her weights, and she lifted in unison. She didn't pay too much attention to the barbell, or her body, she simply focused on that equine. The weights felt a bit heavy at first, yet every time she lifted them up into the air, the weights felt a bit lighter than before. She lowered the weights down to her chest, and then the weights felt slightly heavier. It was a repeating pattern of the weights getting lighter, then heavier. She could feel her chest tighten, and then loosen up a bit. She glanced down briefly, and noticed bulges coming from underneath her top. "Muscles." She said quietly, with a small smile. She glanced back at the screen, and continued her workout.



"You might have asked yourself at one point why none of us have changed with you." The equine said while she lifted weights. "We didn't drink the mix! If you really want to see more changes though, you'll just have to watch the special features." The equine grinned at the camera while she lifted weights. Beads of sweat could be seen dripping down from her body as the lights from above shined on her body.



Sarah continued to watch the equine speak. The detail from the horse's sweat, the lighting, and even the hide she could make out almost made her think of those anthros actually were real. Sarah also kept lifting the weights up and down, but she didn't pay much attention to how much she was lifting. She was unaware that the barbells indeed gained more weight the more she lifted, though even when the barbells grew heavier, it still felt largely the same. She lifted up the barbell easily, and it came down a bit heavier, but still manageable, especially for her muscles as they grew toned, and then slowly to the size of a bodybuilder. Her top began to strain, and her bra snapped as the muscles packed onto her. She didn't grow big enough to rip the top off, but her newly grown muscles were easily shown.



"Five more, four, three, two, one, and stop!" The equine called out. "Well, unless you want more muscles, in which case, just pause the video and keep lifting."



Sarah paused when the equine told her to do so. She looked down at her chest, and smiled. Her breast was still visible on top of her muscles, though she looked like a muscular sexy bodybuilder. Her legs, her arms, her chest, all of them were muscular, and she got that way so quickly too. She shifted down, and then sat up on the bench. She checked the dumbbells, and her eyes widened when she noticed the weights were no longer 20 pounds each, but a total of 100 pounds each. "Unbelievable..." she said quietly. She wasn't sure how the DVD was doing all it was doing, but then again, she had no idea how the protein mix even worked, yet it gave amazing results.



"Now, that concludes this portion of the workout. Make sure to work out regularly if you want to keep those muscles. If you want to do the SPECIAL workout though, just select part two in the DVD. Until next time, enjoy your new body!" The equine waved, as did all of the other anthros behind her. The DVD then went back to the main menu, and music that resembled that of disco music played.



Sarah looked at the cheesy menu. The screen looked more as if it belonged on an old website rather than a current day DVD. She then looked down at herself, and how strong she was. "I guess there's no harm in seeing what the special workout is." With a casual shrug, she pressed the buttons on her remote to see what the special workout contained.



The video began with the equine once more, however the room she was in was different. The room was dark around her, with a single lone light focused on her. She was also completely naked, and she revealed an equine cock between her crossed legs. "Hello there." She said, in a calm voice. "If you're watching this part of the video, I bet you're big and muscular. You're still human at the end of the day though. You're completely normal by any human standards out there. This workout will change that. If you choose to continue, you will become an anthro. Which animal is hard to say, ideally it will be the one you choose, but you'll still be the same height, and just as muscular. If you wish to keep going, pause the video, drink all of the protein mix, and then resume the video, and we shall begin."



Sarah paused the video, and stared at the naked anthro horse. "Become an anthro?" she found it hard to believe, but this was the same video that gave her a bodybuilder build. She wasn't entirely sure if she should become an anthro. She can't say she had seen any of them outside of her house. "If it's like the other exercises though," she looked at the drink. "It should be reversible." She took a swig of her drink, and then another. After a moment, she emptied out her bottle, and tossed it aside. "I guess I'll try it for a moment. If I'm uncomfortable, I'll just turn it off." She hit the resume button on her remote, and watched.



"We will start simple" The equine stated as the DVD resumed. "You must first undress. This should not be a problem for you if you are in your own house. I'll wait for you, so you don't have to keep pausing the video."



Sarah definitely was alone in her house, but she was still uncertain about undressing. The DVD had done so many strange things with her, whether it was causing things to appear in her house, or speak to her in a manner that felt more direct than a video should have been able to speak. "I guess..." she was hesitant, but she took off her exercise outfit and revealed her naked body. Underneath, she showed off just how muscular she had become thanks to the video. Her skin was smooth below her head, and her breast was still very much visible, just poked out on top of all of that muscle she had grown. Sarah took this time to smile down at the muscles she had, and she couldn't help but flex. She had to put trust into this DVD. It had already given her so much, far more than any workout DVD she had ever known.



"Now, sit down and cross your legs, just like how I'm sitting." The equine said calmly, only moments after Sarah undressed. "Take deep breaths, close your eyes, and think of your favorite animal."



Sarah didn't question how the equine seemingly knew that Sarah was now naked. She sat down on the floor, and positioned herself like the equine. She reached out her arms, and folded her thumb and index finger together. "Favorite animal..." she said quietly. She closed her eyes, and pictured a cat. She was a cat person, but her place didn't allow for cats unfortunately. She smiled at the thought of a cat in her bed, in her lap, and just so many moments of doing dumb things, like climbing into boxes.



"As you imagine your favorite animal, picture the ears and the tail of that animal only, if any. Now, picture them on yourself. If those ears can twitch, imagine them twitching. If that tail moves, imagine it moving. Imagine it being, not just on you, but an extension of yourself." As the equine spoke, quiet music played with the sound of a distant waterfall, as if to help relax the viewer.



Sarah did as the video instructed. She pictured herself with a black cat tail and ears, and she imagined them twitching. As she imagined those animal parts, she felt her ears twitch, and she could feel her spine move at the end. Her ears shifted upwards and became pointed, while her spine extended out from just above her rear. As her ears pointed upwards, they took on a triangular shape and pointed up above her head. Skin grew out with her spine, though it left her with a slim tail. Black fur covered her ears and tail to give her feline ears and a slim furry tail with short fur. Sarah could feel her ears twitch atop her head. She reached up to feel those ears, and took a deep breath. She was speechless. She didn't want to open her eyes, but she could just tell that those ears of hers were now feline, and she could feel her spine shift behind her with the tail she now had.



"Don't lose focus when you feel your body changing." The equine instructed. "Just continue to imagine the changes. Imagine the creature's eyes, their paws, their scales or fur. Picture the creature's features growing on your body. Clear your mind of everything else, except that creature you want to be."

 

Sarah continued to follow the instructions of the equine. She briefly thought of the horse in her head, but she quickly got rid of that image. She imagined that equine cock between the horse's legs though, and she couldn't get it out of her head. She wondered if the equine used to be human too, and what gender that equine used to be. Sarah tried to picture the other cat features, but the equine cock stuck in her mind firmly. Black fur sprouted all over her body and grew out only a few inches, but with still enough fur to cover her from head to toe. Her fingernails and toenails shrank underneath her hands and feet, while pink paw pads appeared on every digit, as well as on the palms of her hands, as well as arches of her feet. She could also feel something between her legs pulse and throb to life, though she didn't want to open her eyes to see what it was. She had a feeling, as she couldn't get the picture of the shaft from her head, but she wanted to mentally deny it.



"Continue to focus. If you feel something is off, try to think of it as something else. If the animal has whiskers, imagine the whiskers, the nose, every detail that animal has, put on you. When you think you are finished, open your eyes, and look at the new you."



Sarah imagined the finer details on her body, and she felt a slight tingling sensation as her nose shifted. Whiskers poked out of her shrinking, pinking, nose. Her eyes, while closed, became yellow cat slit eyes, while the previous colors faded away. The hair on her head stuck, but other than that, the rest of her body had changed into that of an anthro. She still couldn't get the idea of that equine cock out of her head, and she felt a throbbing pulsing sensation between her legs. The new addition felt incredibly sensitive between her legs. She couldn't help but reach down and feel it, and the moment she felt that new addition, she gasped and opened her eyes. She looked down at her naked buff body, and she saw herself covered in black cat fur from head to her new pawed feet. Her paw feet had an arch on the back, and while she couldn't see her nails, she could still feel them underneath the fur. She focused for a moment, and revealed white claws underneath she could take back and forth at will. It wasn't her paws she was entirely focused on though, it was that equine cock between her legs.



While the equine shaft wasn't as big as the one the horse had in the video, it was still a good foot long, molted with a flat head, and two large equine balls to go with it. Sarah reached down past the cock, and felt her feline cunt beyond it. She was a herm, a muscular cat girl herm with an equine shaft. She made her way to a mirror to get a better look at herself, and her eyes widened.



Sarah's ears were at the top of her head, just as she felt earlier. They were triangular, black, furry feline ears. Her face was still in the shape of a human's own, but her teeth were sharp, her tongue had the texture of sandpaper, and her eyes, and nose, were that of a feline's. Her chest, arms, and legs were covered with black fur, but still muscular. She still had that shape of the bodybuilder. Her hands had hidden claws underneath her fingers, while her feet were far more like feline paws than human legs. They stood at an angle. She also still had that feline tail, and equine cock that throbbed in front of her with arousal. She wasn't sure if she could orgasm with it, but deep down, something told her that she could.



Sarah turned back to the DVD, and noticed it went back to the main menu. She looked back at herself, and she remembered what the video said about the protein mix. She reached down with her fuzzy hand, and grabbed that new cock of hers. A few quick strokes was enough to make her shudder, purr, and orgasm into the mirror with a lewd meow. Even she was amazed with how sensitive she was, but at the same time, how GOOD it felt to have her shaft touched. Her equine balls pulsed and emptied their seed all over the front of the mirror, while Sarah stood there with her body stiff, and mind hazy during the orgasm. She came at least twice the amount of that of what a normal human could have.



Once Sarah was done with her orgasm, the equine cock grew flaccid, and retreated back into the sheath it had grown. Sarah looked down at the cock, and then at the messy mirror. With a purr, she grinned.

"I got to get myself more of that protein mix."
