A Gym Rat to a Stallion

Linda had been going to the gym for two years, working hard to keep in shape and start to possibly bulk up a little. Growing up with two older brothers, she had always been compared in strength and masculinity even though she was a girl. She didn't mind, but she also knew she wasn't a guy. At least in muscle and height.

So she had been going to the gym, lifting weights and running, watching her calories and sweet intake. Linda was pretty proud of herself, able to lift 150 and run for miles without stopping. Now her family had nothing to complain about. But she still feels like it's not enough.

"Hey, Linda, good work today!" Linda looks over at her trainer, John. He's a 6'3" male with large biceps, a great workout trainer.

"Thanks, John, I'm getting close to my goal for lifting. I know just a few more weeks maybe," Linda responds, reaching down for her towel and water bottle. Sweat was pouring off her body, making her tan skin glisten in the gym lights.

John nods, picking up his gym bag. "For sure. I'll see you Friday," John says, waving as he leaves towards the door.

Raising her hand to wave goodbye, she calls out "See you then." Linda grabs her stuff and makes her way towards the showers since she likes to leave the gym clean. It's easier and doesn't stink up her car on the way home. Making her way to the back with the showers, her head is down looking at the messages on her phones so she doesn't see the person right in front of her.

"Oh, ugh watch it!" someone yells at her.

Looking up startled, Linda immediately apologizes. "I'm so sorry, I was not looking where I was going."

The guy who she ran into was short and a little chubby, a look of annoyance and disgust on his face. "Yeah you should watch it, it's rude to bump into people like that."

Linda raises her hands, "Really, so sorry," she apologizes again.

The guy scoffs, rolling his eyes. "Whatever. A girl like you shouldn't even be here, looking like that. Do you think guys want a girl so beefy and muscled? Right now you are headed on your way to look more like a man, bet you are a stallion with all the woman you get? Hahahaha," the man laughs, a mocking look on your face.

He thinks he is making fun of Linda, but Linda doesn't give a shit. "Um, who cares what I look like or who I would date? It's none of your business anyways. I apologized and now you are being rude. Goodbye sir," Linda replies, a little harshly now that this guy has gotten on her nerves. With that, she turns around and heads for the doors, ready to leave. After that interaction she just wants to head home and be alone, she'll take a shower at home.

In her car, she fumes as she thinks about the interaction. Who did that guy think he is? Such a jackass! Whatever, Linda thinks, finally making it home. Hopefully, she'll never see him again, and if she does she can complain to the gym workers. She's been going there for years and knows everyone so it shouldn't be a problem. Besides, she likes how bulky she's been getting, so his words mean nothing to her.

It was late, time for a shower, dinner, and bed. She had work tomorrow at the clothing store she's been working at for the past few months. It was barely enough to get the money she needed, but she had no idea where else she would work.

Linda climbs in the shower, rubbing down her body with her coconut-smelling shampoo. The lathers and the hot water feels so good on her skin after a hard workout. Her lavender shampoo rinses out of her brown hair, the suds running down the drain.

After she finishes, Linda gets out to dry off. Wiping away the shower fog, she takes in her appearance in the mirror. She can't help but flex her small but there muscles, proud of what she has accomplished so far. Her abs flex too, small boobs barely bobbing with her movements. Shaking her head at her silliness, she wraps a robe around her body and heads out to the kitchen to make dinner. Linda's stomach is grumbling up a storm, and she's feeling a big, healthy salad tonight. Luckily she has all the ingredients, like carrots and lettuce.

The meal is perfect but not really filling enough. But she can't snack or eat more because of her calorie counting, so she'll just have a protein-filled breakfast tomorrow. Yawning, she walks into her room and prepares for bed.

But a whiff of something awful fills her nose as she walks around her room. Checking her dirty gym clothes which are in the hamper, they just smell like her normal BO. Not knowing what else it could be, she searches around in case it's something important. But Linda can't find anything. Until she raises her arms and smells herself. Her own BO is wafting around her, smelling up her room. It's nasty and bitter, which is crazy since she just took shower. Shrugging, she heads to her bed, deciding she's too tired to do anything about it tonight. She'll just take another shower in the morning.

Walking up, Linda groans as her sore muscles move. The long stretch feels amazing, flexing her muscles and body as she presses the stop on her alarm. That odor she smelt last night is still present as she shifts, filling her nose. Right, a shower and then work.

Walking towards the bathroom, Linda scratches behind her. Right above her ass itches badly, and so do her arms. Maybe she's allergic to her new detergent?

When she is in the shower she makes sure to scrub down all of her body with her soap, wanting that smell to go. Linda also notices she is due for a shave on her legs and privates but she doesn't have time to deal with that today. Her job requires her to wear pants anyway so she can cover her legs.

Speaking of her pants, none seem to be fitting. Linda is having trouble pulling them up over her thighs and ass. Her assets look thick and muscly, like normal but she doesn't understand why her pants aren't fitting at all. They were fine yesterday. Maybe she's just swollen from yesterday's workout, yeah that makes sense.

Finally, she finds a stretchy pair of black pants that barely pull over her butt and thighs, the elastic top stretching over her abs. A white blouse for her shirt and a small pair of black heels for the rest of her outfit. Lifting her arms she jerks back as the strong odor reaches her nose again. Linda has no idea what is going on with her body but she can't shower again. Deciding to just lather on more deodorant and perfume, Linda leaves for work.

Her commute isn't far, the drive relaxing since she can avoid most of the traffic on the way there. Home on the other hand is another deal. But with Weezer playing on the radio and the window in her hair she feels good. Her body feels like it's pulsing, her blood running quickly through her. Linda realizes though with a grumble in her stomach she forgot to eat this morning. Luckily her work has a back room where she can grab a snack before she starts.

Once she gets there the store is already open and running by her two coworkers and manager on duty with her today. Liz and Jessie were fun to work with, but her manager Kathy was super strict. Linda isn't late so she didn't have to worry about that but her boss still scares her sometimes.

Walking in, Linda clocks her time and grabs a quick granola bar in the back. It doesn't sound good at all, nor stop the grumbling in her stomach but it will have to do. Walking into the front towards the cash registers, Linda waves hi to her fellow coworkers.

"Hey guys, any customers yet?" Linda asks, signing in to her register.

They smile and wave back, shaking their head in denial. "Nope, been quiet this morning luckily. Hopefully, it will stay like that all day," Jessie replies.

Linda smiles, itching her stomach. "Yeah me too, not ready for another long day of work."

Liz nods in agreement. "Yeah, last weekend was roughhhh! But we did get something new-- oh, wow what is that smell?" Liz complains, moving her hand in front of her nose.

Jessie sniffs and quickly covers her too. "Oh yeah, it smells rancid like a barn or something?"

Linda laughs and rubs her head. "Oh man, I drove past a dead animal on the side of the street on the way here. You know how sometimes those things stink up your car. Sorry, does anyone have any perfume?" Linda replies, a little worried and sheepish. Her weird smell was permeating the room, her earlier deodorant doing nothing. Hopefully, her cover story will work until she figures out what is going on.

Liz nods and pulls out a bottle. Grateful Linda sprays the bottle on her skin, hoping and praying it will work.

The first half of the morning goes by smoothly, barely any customers come in which is good. It gives them time to chat and talk, gossip, and whatever. Their boss hasn't arrived yet which is a relief since she hates when they are slacking off, even when nobody is in the store. Their little clothing store for older women is super cute and chic, definitely not Linda's style at all. But it pays well.

Linda does have to subtly shift and pull her pants a few times, the stretchy black pants feeling tight around her crotch like it's riding up. They are itchy too on her thighs, distracting her a couple of times throughout the morning.

It wasn't until about lunchtime where Linda really felt something off in her stomach. The rumbles were loud enough to be heard across the room, but it was the cramping that really made her grunt out loud. She could feel herself needing to use the bathroom but she hated doing that in the store. They only had one bathroom which was for customers and employees. But her stomach wasn't giving any room for her to hold it. She could feel the rumbles moving lower towards her asshole. Clinching, she excused herself and wobbled awkwardly towards the bathroom. Farts escaped as she went, another awful smell following behind her.

Finally, she made it in and ripped down her pants, squatting over the toilet. With a grunt she pushed out her shit, large splats landing in the toilet behind her. Loud, wet farts escaped while she went, but Linda's just glad she made it to the toilet on time. The logs just kept coming and coming, filling the toilet behind her. When she was finally done, Linda took a breath of relief but soon came the piss that usually followed a massive shit. The pee stung slightly as it came out, but it was a relief too. Wiping as much as she could, Linda finished and stood up. Again struggling with her pants, her thighs looking much larger, her abs a little less noticeable, she turns to flush. The amount she went was crazy, she didn't think she had it in her since she barely ate breakfast.

Washing her hands Linda looked in the mirror. Her face was red and flush from her almost exercise of using the bathroom. Wait, do her nostrils look wider to her? She must be imagining.

Leaving the bathroom there is a customer waiting outside. She looks annoyed, tapping her foot as she waits.

"Sorry about that, it's free now," Linda comments, a little embarrassed as she leaves.

The woman rolls her eyes and walks in.

"Oh ew! What is that smell?" the lady comments, plugging her nose.

Linda flushes and turns even redder. "Oh, it smelled like that when I went in. Here, let me spray it for you." Linda quickly sprays the room and leaves back towards the counter. Walking back, she notices her manager was finally back.

"There you are Linda, I was just telling the girls someone needs to check in the new clothes that just arrived," Kathy comments, tapping her pen on the counter.

Linda smiles, not noticing her teeth are a little larger than usual. "Oh, I can do that. My shift is almost over but I can do that before I leave."

Kathy nods and writes something down. "Good, it's in the back. See that it's finished before you go. Oh and Linda, you need to dress according to the policy of the store next time. We don't allow any stomach to be revealed here, you know that."

Confused, Linda looks down and notices her shift is riding up. Her stomach is swollen, pushing up against her blouse and revealing a little skin. She also has some hair lining under her belly button, which definitely wasn't there this morning. Awkwardly tugging her shirt down, Linda smiles and nods.

Walking towards the back in a small little break room she notices a huge box for check-in. Opening it up and plopping down on her ass, a little more cushiony than before, she gets to work. The clothes are cute, really in style and good for the upcoming fall season. On one shirt there is a llama, which is really funny but not really fitting for the customer types they have. But she likes llamas, their long necks make her laugh. But not her favorite animals, she loves cows! Cows give milk, which helps strengthen bones which she needs while she works out.

Thinking about barn animals, she can't help it as her mind shifts to other animals. Like pigs or donkeys.. Or horses. The thought of a horse makes heat rush down her body. Why... why was thinking of a horse getting her this bothered? Big horses are sure strong and powerful, everything she's always wanted to be. Those huge thighs, strong forearms, big ass...

Linda comes back to herself and notices she's rocking forward, grinding her pussy into her shoe. It feels good, but she can't be doing that here! Ashamed she leans back to stop. But looking down she can see a bump in the front of her tight, very tight now, leggings. Is that here clit? It's so engorged, she must be so turned on for some reason. And because of a horse?

She needs to finish this work quickly and leave. Maybe a good workout will clear her mind.

It doesn't. Her mind keeps drifting as she does some sit-ups. Weirdly it's her mind towards the one thing that she never thought she would ever think about. How do horses mate? Those heavy, powerful stallions mounting a mare, those meaty stallion thighs thrusting. Her mind is running wild with the thought, she's so turned on and Linda can feel her clit throbbing in her pants.

Sweat pours down the face and skin as she finishes for the day. She feels itchy and sweaty, hungry, and tired. And mostly horny. Luckily Linda didn't run into that annoying guy from yesterday, which was a relief.

On the drive home, she didn't even notice how her ass filled her seat more than usual, nor how she didn't take a shower like usual. Linda's mind was on dinner.

Dinner consisted of a salad and carrots again. The meal went down quickly. It was not enough so she ate more, finished off the rest of her veggies in her fridge.

"Man, I'm going to need to go to the store tomorrow."

Exhausted, she gets ready for bed, ready to watch a show and relax. Linda picks some random cooking show, but her mind again travels. Her body feels hot, tight. Automatically she rubs up and down her thick thighs and stomach, noticing how bloated it feels. Her abs are gone, replaced by... Is that a layer of fat? How is that possible?

But more concerning is the layer of dark hair that covers her body. "Oh man, I really need to shave," she mutters to herself, rubbing her hands through the coarse hair on her stomach and arms. The action gets her going through, that pulse in her crotch starting again. Moaning Linda reaches down to rub her clit, little circles as she starts up. It feels so good, heavenly. Her clit is hard, feels bigger than normal. She looks down and pulls down her PJ pants, looks at her crotch which is covered in thick, black hair. Peeking up is her straining clit, glistening wet. It's never gotten this big, her body doesn't react like this when she's turned on.

"What the hell is wrong with my body?" She groans out, rubbing hard on her throbbing clit. The action sends tingles down her body. Arching her mind flashes back to horses again for some reason, the thought of a humongous ass and powerful muscles. She would be so strong, muscles bulging as she ran through fields. Her cock too, bulging and huge, is normal for her type of breed. The thought makes her come, back arches and eyes crossed. Her orgasm is strong, making her tense and shake.

When she finishes, Linda gasps and lays on her back taking huge breaths. She can't believe she came that hard. With a sigh she looks at her clit, it's throbbing from her organism, and is it even more swollen? With a shrug and a yawn, she turns off her lights and goes to sleep.

In the morning she wakes to something itching her ass, her back arches weirdly while she lays on her back. Groaning, she turns and gets off her bed, muscles aching again. Eyes barely open she walks to the bathroom, itching above her now frankly huge ass though she doesn't realize yet. When she gets in the bathroom and flicks on the lights, Linda lets out a huge gasp as she takes in her appearance.

Her nose is swollen, nostrils are definitely wider than normal. Her ears look longer too, hair peeking out from within. Her stomach is definitely wide now, barreling in shape instead of the flat abs she uses to have. Thighs now loaded with large muscles, so wide and big they touch as she stands feet wide apart.

"What the fuck is wrong with my body?!" Linda shrieks, concerned and worried. Looking down she notices a little tent on her PJ pants too. With shaky hands, she pulls them down and takes in her swollen clit. It's about two inches long now, definitely not normal. It's red, throbbing slightly. But something tickling behind her makes her turn around.

Linda's heart stops as she notices something long and hairy sticking out above her ass. Speaking of her ass, why is it so big? But the long thing, it's swishing behind her, tickling her lower cheeks. A tail, she has a tail!

"Oh please, no!" She cries, gripping the thing behind her. With a pull, it's definitely attached to her, the skin tight and a little darker around where it's connected. The tail is covered in long, black hair too. Rubbing her other hand on the curve of her huge ass, she takes deep breaths to control her racing heart.

There must be an explanation. Maybe she's still dreaming, or... she's been kidnapped and placed in a virtual simulator! Yes, that must be the explanation.

But an unexpected fart rips out of her ass, blowing back some of the hair on her tail. "Oh, ugh!" Linda grunts, back arching as she feels more farts being let out behind her. In the closed bathroom, the smell surrounds her. The enlarged nostrils are not helping block out the smell. It smells like.. manure, like a barn.

"Why? Why me?" She speaks into the empty ass, head back as she lets out another wet fart, the action jiggling her cheeks. Head turned away now she doesn't notice that her asshole is now black and swollen like a donut. Her cheeks slowly spreading apart behind her too.

With a rumble, Linda feels another thing in her stomach that she knows isn't a fart. Eyes wide, she races to the toilet beside her and barely sits in time for her stomach to release. Tail unconsciously up, she pushes the logs out behind her, splashes as it lands in the toilet. The action comes fast, her pushing and tail up natural. With her hand's braces on her hairy thighs, she grunts as she finishes her load.

When she's done, she turns to wipe, but it barely does anything. Her shit in the toilet is large, almost like horse or cow manure instead of a human. Standing up she tries to flush but the toilet gets clogged, just her luck. Too in shock and annoyed to do anything, she leaves it be for now.

Walking naked to the kitchen her stomach rumbles again, this time for food. Oh yeah, she's out of anything good. Deciding she needs to go to the store, despite this weird new appearance, she walks to her room to get dressed.

Linda finds some sweat pants that pull over her widening lower half. The clothes stretch tight, almost revealing the darker growing hair underneath. Her asshole rubs on the back of her pants, as she notices her cheeks are spreading apart. The tail falls between her spread cheeks, tickling her asshole. Her clit is no longer hard but still longer than usual, creating a tiny bulge in her pants.

Throwing on a sweatshirt too, her bulging arms make the sleeves tight. She can't help but admit the sight in the mirror since muscles like these are what she's been working towards forever. Her feet are a little swollen too, but they fit in her regular jogging shoes.

Heading out to the store, she doesn't even remember to check for her scent, she's used to the rancid smell by now. But her stomach is hungry, rumbles ring as she drives to the store. The seat belt is tight around her body, but not because she's fatter. Its muscle, she can't tell as her swollen arms flex.

Walking into the store, she doesn't notice her walk is a little wobbly nor how hunched over she is. Linda's back is stretching and flexing, her huge ass making her walk with it sticking out a little.

The grocery store was packed on this nice morning, with many shoppers getting produce and food. Grabbing a cart Linda walks over towards the produce section. Her mouth waters, lips jiggling as she sees all the produce. Carrots and apples... but her mind wanders to something else as well. Hay... Grass... that sounds good as well. She doesn't think they sell that in the grocery store though. Does she need to go to a barn or farm?

"Um, excuse me sir as you are done with the lettuce?" someone asks Linda.

Looking over she notices a young woman, smiling and pointing towards the greens Linda is standing in front of.

"Hm, oh sorry. Yes, I'm fini-AYY!" Linda blurts out. Surprised she covers her mouth, eyes wide towards the lady.

The other lady looks surprised too. "Oh! Um, excuse you sir?" she says, a little hesitant.

Linda blushes and looks at the woman in confusion. "No, excuse me. But sir?" she asks. Why is this lady calling her a sir?

The woman's eyes flicker down for a second, barely noticeable if Linda wasn't watching her. Looking down to follow her eyes, she looks at the front of her pants. There is a bulge, an actual bulge pushing out the front of her pants. Is that her clit? It looks so much bigger than this morning, more than a couple of itches now. What the actual fuck is going on with her? But looking down at her clit, looking at it gets her a little bothered. Oh fuck, is she growing a dick? The thought actually doesn't bother her as much as it should. It actually is really hot. She has always wondered what it's like to have a dick. A big, huge, heavy dick. The bulge in her pants rises, pushing up the front of her pants more. Her sweatpants are already tight from her ass but the front now is tight too.

"Oh! Um..." the lady says, backing away slowly. Linda raises her eyes, face hot and embarrassed.

"I'm so sorry, I don-AYY" Another one of those unexpected noises! It sounds like a bray or neighs!

"Nevermind, I'm fine," the lady says, backing fully away now.

Linda watches her go in shame. What is wrong with her? She was truly transforming into something else.

Finished with the produce, Linda walks around the rest of the story quickly making sure she isn't forgetting anything else she needs. Nothing really sounds appealing, besides hay for some reason. Everything else makes her feel sick to her stomach. No, wait... That's something else.

"Oh no! Please not here!" Linda pleads out loud to herself. Stomach grumbling, But she can't help break wind behind her. The manure smell spreads around her, almost covering her in a layer of its smell. More wet farts escape, pushing up her tail in her pants. Grunting, she leans over the cart and arches her back. Without her consent, her asshole pulses before opening, pushing out more shit somehow. It fills the back of her pants, covering her tail and ass since it's all just down the back of her pants.

"Oh my God! Are you using the restroom?!" someone shouts near here. Looking over, Linda notices someone else on the aisle, eyes wide in disgust. With a cry Linda continues to push, the shit sliding down her pants. It smells so bad.

Tears escaping her eyes, Linda looks around frantically. She can't believe she just did that, shit in a store in front of people. It's like she lost control of her own body. Linda runs out of the store, grabbing her stuff and leaving a flock of people gossiping behind her. Stealing was the least of her problems right now. The manure slides down the leg of her pant, leaving a stain on the outside too. Crying full out she gets in the car and drives home. The ride is uncomfortable, as sitting in her own waste is the worst thing ever.

Finally, back home she jumps in the shower and takes off her tight clothes. She uses what she can of her clothes to wipe away the mess, rinsing the rest down the shower. It's nasty, smelly, horrible. In the middle of wiping down, Linda cries out and arches, feeling her ass physically grow this time. It's like a sharp warmth in her ass, making her bottom-heavy. Looking backward through tears she watches as her thighs and ass grow even bigger, her black, dirty asshole out and visible.

When the warmth leaves, Linda turns off the shower and slowly gets out, her back aching and tight. The mirror reveals her changed features, her large teeth, and her swollen nose. Her body is not even her anymore, big and bulky, covered in black hair. Her pussy was no longer a pussy, her clit was more like a dick at this point. It was long, about 5 inches, and reddish black. Linda could even see a flared head starting to grow at the end.

"Am I even a girl anymore? Am I a he?" she asks herself.

Going naked she leaves the bathroom and heads towards the counter where she left the produce she stole. Scarfing down the food leaves her unsatisfied and hungry, but it's all she has. Today has been a long day, and she's ready for bed. Once in bed, the sheets twisted and sweaty, Linda settles down for sleep, but as her mind wanders and she almost drifts off, her stomach twists like a cramp.

"Oh, owAYYY," she grunts, hands moving to her lower stomach. The cramp worsens, a ball of sickness almost making her way up her throat from the pain. Grunting, she feels like she needs to push for some reason. Pushing with all her might, Linda groans in pain into her pillow. Legs pulled up, toes curled, it feels like something is sliding out of her. Each push is moving that thing down until it reaches the edge of her vagina hole. With one more grunt, the thing comes out, laying underneath her.

Exhausted Linda leans her head back breathing hard. Whatever that was, it wore her out, and with that, her eyes close.

All night her dreams are filled with glimpses of a big, brown, and white ass in front of her. Fields and grass stretching for miles. The smell of something musty and delicious. She thrust into something wet and tight before her, a body similar to hers underneath her.

With a gasp, Linda woke up, a little disoriented from things around her. Her body felt even bigger, heavier. Rolling out of bed she ran her feet through the carpet. She could barely feel anything. Looking down she noticed most of her toes had molded together, her feet darkening.

"Oh, hooves..." she mutters. A little out of it Linda stands to head to the kitchen. But when she stands she is shocked to feel something hanging underneath her. Glancing down her bigger eyes take in her dick. It's way longer now, about 9 inches and thick. The color is brown and black, the head is huge. But underneath is a pair of balls, as big as kiwis. They sit in a low-hanging sack, covered in the same black fur the rest of her body seems to be covered in. Heavy, full, the tug on her taint. Walking experimentally, her dick and balls swing and slap against her leg as she walks. "Oh fuck!" Linda exclaims the feeling is so good.

"I have a dick and balls!" She exclaims, reaching down to touch the thing. Her hands seem to be changing too, but she can still grip her new equipment. The first touch is lightning, heat traveling through her body.

"Neigh! Neigh!" She calls out, her head thrown back in pleasure as she moves her hands up and down her cock. As she rubs she can feel it growing, hardening but also growing longer. Eyes blurry as she watches moans leave her constantly. Her balls don't want to be left out either. They swell, becoming apple size. Cum fills them, making them hang lower towards the ground. The whole process is so hot, so erotic, and mind-numbingly good! With a bray she comes hard, cum spurting out her now 14-inch dick. Her balls are tight, emptying gratefully.

It takes a few minutes for her to finish, or is she now fully a he? Balls empty, cum staining the floor, Linda takes a deep breath. Her lungs expanding and her chest barrelling more and more.

Good, it was so good. Like a horse, a big stallion, he thinks to himself. Turning towards the door to the outside, Linda walks/wobbles towards the door. All he can think about is food. Grass would be nice. Once outside he falls to his hands and knees. Linda shoves his face into the ground, ripping up a large portion of the yellow meal. It's yummy, filling, and the dried-up grass is a perfect meal.

During his time on the ground, his changes finish up. His body continues to bulk up, arms lengthening with a crack, his knees following. Hands and feet quickly turn to hooves, hardening and turning a dark color. He can no longer feel them, but his body automatically adjusts so his legs fold out so he is standing on his back hooves now. Ass in the air out for everyone to see.

Next is his spine, lengthening and cracking behind him. His tail whips behind him as he starts to properly shape into a real horse. A real stallion. Chest growing larger and larger, muscles continuing to build on top of each other in order for the stallion to be able to hold themselves up.

Leaning up to chew, Linda looks blankly ahead as his face pushes forward into a snout. His face was already close to it, but it was finally taking the right shape. Ears lengthened and covered in hair, moving painlessly to the top of his head.

Balls grew heavier, pulling up closer under his asshole. His cock lengthened and widened, a ring of flash in the middle. More flesh pulled up around the 20-inch cock, becoming a sheath to hold up the massive thing. It's sweaty, smelly musk being wrapped in a hairy layer pressed up against his stomach.

Mind blanking Linda continues to graze as the changes turn final. Long brown hair turns black and rough, a mane complementing his short black hair all over his body.

He, once a gym lifting she, is now a large, virile stallion ready to mate with mares. The only thought in his brain is running in fields to become stronger and thrusting his large cock in a warm mare pussy. His life on a farm breeding mares is his only concern now.
