===

It turns out getting laid was harder than I thought it would be, my hookup apps only showed guys 100s of miles away, and it wasn't like my town was big enough for a gay bar. Hell, the bar had to double as a grocery store just to stay afloat, and it closed after 9PM.

I slowly began to remember all the many reasons I'd moved to the city.

I'd decided to stick to the front half of the farm, where there were people about after my unfortunate hole incident. I was slowly walking, the morning was a bit chilly, and I'd put on a hoodie. I had some new jeans I'd put on too, my mom had found some maternity jeans my sister had worn in an old box, and I didn't have the heart to tell her no as she pushed them onto me. The worst part was, they fit. I'd grumbled at that when I'd put them on this morning, it was better than the cuffed up pair of pants I'd been using. I swear, if they'd gotten any bigger on me, they would have been my old JNCOs. Between those, the sex dream, and the feelings of isolation, I was really starting to feel like I was in high school again.

It was still pretty early, the sky was a weird mix of purple, yellows, reds, and grays. The whole world looked like an insta-prey filter. I kicked a rock, and I watched it skid into a patch of rattle grass. The rattlesnake tail like seed pods at the end rattled, and it sent a shuddering noise into the quiet morning. They eventually calmed down, but only after a feral pygmy griffin in a nearby tree flew away. I was going to have to tell mom to keep the cats inside for a few weeks.

Dealing with kittens who could fly was always a pain.

I kept walking, and I slowly drifted to the barn where they kept the dairy goats. I walked through some of the outer rooms, where they made cheese for the farmer's market, and where they bottled it up for sale to the mass market.

I walked out of the back, and I saw a curious sight. Shane was sitting on a small stool, his massive frame dwarfing the little thing, and there was a very indifferent looking dairy goat tied up in front of him. He had a little pail under her, and I started to watch as he milked the very pregnant goat into the bucket.

"That's a good girl," he cooed as his paws slowly worked her milk into the bucket. He grabbed her teats with skill, occasionally reaching up to rub at her heavy belly, before going back to his task. "That's it, just let it all out."

"You know you won't be able to use that milk, right?" I asked as I leaned against the door frame that led into the little side yard between buildings.

He nearly jumped when he heard me, "Oh uh Miss Landing," he paused, "Oh fuck, uh, I mean Mr. Landing, I'm sorry, I didn't see you there." He said, a blush spreading across his face again. He patted the goat's side, "Yeah, I know, the bucket isn't sterile, and I do keep touching her fur. I won't pour it into the larger vats or anything." He looked embarrassed, "I'm not a fool, you know?"

"So then why are you doing that?" I asked.

"Oh! Karry here gets nervous getting milked, this is her first kid, and she's tried to break out of the milking stalls a few times. I'm hoping I can ease her into it, and get her onto the milker," he shifted, "your dad said he was going to have to cull her if she couldn't be milked."

That was weirdly sweet, normally people didn't care that much to put in that much effort. I also found myself oddly jealous as he touched her belly, I found my mind wondering and imagining his paws on my belly like the other day, holding me and my foal inside his strong arms. I huffed, my breath curling steamy tendrils in the morning chill.

"That's really cute," I found myself saying, and I enjoyed watching him squirm as I called him that. "But, doesn't that put you pretty far behind taking all that extra time with her?"

"A bit, but I want to give her the best chance, you know? After this, it adds on a little time every day, but she can't help if she's scared," he said. There was a gentle tone to his voice, and he smiled softly. He rubbed at her flank.

Before I could really think about what I was saying, I said, "Well, I could help you out, and get you caught up."

"Really?" He asked, before looking at my belly and blushing. "But with your condition, should you really be doing farm work?"

I put my paws on my hips, and I looked at him with narrow eyes. "I'll have you know, people with 'my condition' have been doing farm work for centuries." I shrugged, and decided to throw him a bone, "Besides, you'll be around if I fall in another hole. So this will be safer exercise than running."

"Okay... but I don't want you lifting heavy stuff or handling the livestock in the mornings. I had a friend whose mom lost a pup after getting kicked in the stomach by a dairy cow, and I'd never forgive myself if that happened to you..." He said, pure concern radiating from him. "And only until I can get Karry into a milking stall."

I slowly began to realize he'd thought I'd meant I'd help him every day, and not just for the next few hours. I opened my mouth to correct him, but I stopped as the idea played through my mind. It was going to be better exercise, and it wasn't like I didn't know how to disinfect the milk room or the other equipment. I mean, it was only until he could train the goat, right?

Deep inside I knew training a goat to do anything was like trying to pull a screw out of a board with a hammer, but the thought of spending more time with Shane had a certain appeal to it. So I decided to go along with it, "Okay, deal."

As we worked that morning, I got the feeling he wasn't really sure how to act around me. He knew I was his boss's son, but I was pregnant, had a penis, and breasts. The change didn't change the way I talked or the way I acted, so I was still a guy... I just had some extra bits and a little higher of a voice. I'd catch him going to swear, and he'd quickly correct it to things like "Darn" or "Sugar". Like he would if he was around a lady. I felt a little weird about it, but I guess deep down I understood. Parts of his brain were screaming "Woman" while other parts screamed "Man". And it wasn't like I'd sat him down and told him exactly how to treat me. I'm sure I was the only boy like this he'd ever met. Marebois are rare after all.

As I was hosing down the milking shed and I was alone with my thoughts, my mind began to wonder. What exactly was my gender now? I wasn't exactly a guy, and I wasn't exactly a girl. Technically I was es-gendered, a term someone came up with in the 60s, the "es" being short for "estrus". But it wasn't like it had exact terms that went with it. I knew of a few people in the support group who had decided to go by female pronouns after their first pregnancy and become more women-like. Some didn't get on the heat blockers, but just kept a close eye on their heat cycles and stayed inside during it.

Others would just get their extra reproductive organs removed, and the heat cycle would just stay away forever, but it crashed your sex drive completely. I didn't recall exactly what it was, but something about the way their magical glands interacted with their biology caused a short circuit and it all to shut down. Going on testosterone or estrogen didn't recover it, it would just be gone forever.

Also... a lot of surgeries had been forced on guys from the 30s to the 70s. They'd get raped, have their rapist's baby, and then the judge would sentence them to have a hysterectomy even if they didn't want one. That wasn't even half of it, for longer than that and into the 70s, the person who knocked you up could claim you as their "wife", and you were forced to stay with them and were considered their property. For a lot of years, when you were a mareboi, your gender wasn't exactly your choice in a lot of places. A lot of times you just did what you could to live your best life, and hoped for the best.

So where was I? I'd always fought so hard to stay a pure masculine stallion. Is that the path I still wanted to go down? Was I still that same person now that I was carrying a foal inside of me? I'd never put much thought into my gender before.

I looked like a dude.

I felt like a dude.

I did dude things.

But now my body had other ideas. I was more feminine every day. Did I want to lean into that? Did I want to become someone's mom or was I still going to be their dad? I began to realize that this whole existential crisis was forced onto me by one asshole who decided he had dominion over my body just because he fucked me. He'd called me his mare, and that had angered me so much. I knew in my core then; I was a stallion. That was forever going to be a trauma I was going to have to deal with, for now I was just trying to get through day-by-day.

I wish that answer was that simple now. As my body changed, it was hard to feel like a stallion. It didn't help that I couldn't get it up anymore, and my balls were so small now. They weren't that impressive man-sac they'd been just a few months ago.

So... I had to ask myself. Who is Lucas Landing now?

I was brought out of my thoughts when Shane popped his head in, he smiled at me and said. "I don't think I've ever seen that floor so clean."

"What?" I said, before looking down. Apparently, I'd been washing the same spot on the floor for several minutes. The cement looked almost new. I blushed, and nodded, "I think I spaced out."

"Sounds like I came at the right time," he said, "want to grab some lunch? My treat, it's the least I can do for having you help me out."

"Yeah, I'd like that," I said with a smile.

===

I grew closer to Shane over the next few days. We had lunch a few times, and he even took me to the Chinese buffet two towns away that I'd dreamed about since I'd moved away. We chatted as we worked, finding out what movies we liked, music, and other things. I'd usually be so tired by the time I was done, that I'd end up passing out as soon as I got home.

When I wasn't with Shane, my mind kept wandering back to what I'd been thinking about since that first day since I'd started helping him.

Just who was I now?

I'd look at myself when I got out of the shower, and I felt like a stranger to myself. My body had lost all the definition I'd worked so hard on. I wasn't exactly petite, but I wasn't huge either. I'd gained an hourglass shape... well, it would have been hourglass shaped if it wasn't for the massive pouch of foal on my stomach.

But my breasts had grown, and they'd keep doing so. I'd find myself playing with them sometimes, just kind of in shock at how feminine they'd looked. Even when I was on the Gen-2 heat blockers, and I'd leaked milk, they'd never looked like this. My blond mane had grown softer too. I used to keep it really short, but I hadn't had the energy to keep it trimmed now. It'd grown nearly to my shoulders, and down my back. All of my fur was softer now, which no longer felt like rough wool, but like a fluffy blanket. I'd watched the new fur come in over the course of a week when I shed like crazy. I was picking fur out of everywhere for days after it finally came all the way in. I was even still finding little fur balls in places. My hips and rump had grown too, they were something that would have filled up a pair of "Juicy" yoga pants and made every man in the gym drool.

So how was I still a stallion? I kept wondering to myself.

I still felt like one, sometimes. But other times, I found myself thinking differently, I'd refer to myself as a mare in my head or I'd do something I'd never do as a stallion. Like when I whinnied like a little filly when Shane had gotten me pizza from my favorite pizza place. I found myself connecting with my emotions more, and caring more deeply about them than I had in the past.

But I also still found myself performing those male gendered things. I'd always take up a lot of space, with my baby belly, I never really felt like closing my legs, I'd always sprawl out. I also would find myself always trying to offer a solution, even when I knew someone was only looking for someone to listen to them.

I'd started to get bigger on eye contact though, I found myself wanting to get lost into Shane's emerald eyes, and I'd forget sometimes that someone didn't have to look at me to actually hear me.

Ugh... It was all so confusing. I buried my head in my pillow one night and just screamed as all those thoughts raced through my head.

Being horny as ever loving hell wasn't helping at fucking all... ever since that weird dream about my dad... I'd been even more pent up. I felt a need deep inside of me, just begging to be bred, and I kept wanting to make a move on Shane, but I was worried about scaring him off. He always seemed to shy away from his personal life, I was the boss's daughter... er, well, the son, whatever, so I could understand why he'd be a little shy.

It wasn't stopping me from daydreaming about that shy farm boy just wrecking me though. I would find myself constantly picturing myself sliding up and down on that cock as he filled my ass, my new tits bouncing as the cock between my legs flopped around as I got ready to be filled with his seed. I wanted him to just pin me down in the barn, and just fuck me into the dusty floor until I was walking funny and I was filled with his cum.

I could tell something about me aroused him, occasionally we'd be talking and I could sense a change in his scent as he got aroused. I would find him looking at me longingly sometimes. I kept wondering why he did that. Was it because I looked like a girl sometimes? Was it because I looked like a boy in other instances? Or was it just because he liked me? Was all of this too confusing to him to even think of me in any way other than an acquaintance? I got the feeling he at least liked girls a bit, he'd mentioned a few times that he had ex-girlfriends, but he'd never mention anything about ex-boyfriends. But that might just be due to the size of the town we were in.

I started to think long and hard about how I felt. It wasn't like I would always consider myself as somewhere in between a gender, I always strongly felt one way or the other depending on the day and situation. I just felt like both. I'd begun to slowly figure out that it was fluid, it would seem to move from one to the other. That's when a term popped in my head.

Genderfluid.

I'd heard about it in passing, but I'd never actually looked into it. My vague understanding of the concept made me feel like that might be the label that I could put on this new phase in my life, but I still wasn't sure.

Fuck. Maybe I was something else even. Maybe mareboi was a gender of its own. And I should really lean into the es-gendered term, whatever that meant. Something that I had to learn to become, and figure out what it meant to be one in the world.

===

I'd managed to make it until one hot steamy night a month later. The fyre-flies were bursting into red cold flames as they hopped about. There were a few patches of taller grass that looked like little campfires as the small beetles ate their fill. This all happened outside my window as I stirred inside. It'd been a bad night, I felt so horny, but without being able to jackoff there'd been nothing I could do about it. I was currently whimpering as I shoved a slick werewolf toy in and out of my ass, my cock leaking pre like crazy inside of my sheath, but not able to get close. I bit my lower lip, and I cried out in frustration as I pulled the silicone from me, and tossed it on the pile with the others.

The horse, unicorn horn, the dragon all sat in a pile- seeming to taunt me.

My mane was draped over my face, and I had an exhausted scowl on my face. The fire inside of me begged to be filled, it wasn't as bad as being in heat, but it was pretty damn close. I pushed the fur out of my eyes, and tucked it back behind my ear.

I grumbled and sat up on the towel I'd been laying on. I sighed, and rubbed my forehead, before my eyes traced over my small round home, and they fell on the box.

I gulped as I looked at it.

I needed the real thing... and an idea had been forming on how to do it. I sat up and took a breath. I stood up and used the towel to clean out the inside of my sheath, not as easy with my bigger belly getting in the way. It seemed to grow more difficult with each inch I lost for my cock and each inch I gained in my belly. The doctor said it still might shrink down even more, if that was even possible, and my mind brought up the memory of the pamphlet he'd given me about the benefits of having my sheath removed now that I was a mareboi. I'd balked at the idea a month ago, but as I'd only grown hornier and pre had pretty much constantly filled my sheath, I was starting to see the appeal.

It was just hard to let it go, when I saw myself in the mirror it let me pretend sometimes that I hadn't lost as much of my manhood as I had. If I did that though... what remained of my cock would constantly be on display. Constantly in the open, that limp bit of muscle always reminding me of my new place in life. I bit my lower lip, and I blushed as I realized how much that thought was turning me on. But that was a conversation with myself for another day.

I turned my attention towards the box again. The thing I'd tried to keep my eyes off of the box since it'd arrived, but it kept coming back to my thoughts since I'd started to question my place as a stallion. I shuddered as I opened it and looked down to the note inside.

"To help you decide who you want to be,

Love,

B."

I lifted up the note, and instantly I saw the red lace underneath. I held it up, the moon light filtering through its lacy patterns. It was small, revealing, just a little less cloth than a pair of briefs would be. I took a deep breath, lowered them, and gingerly put one hoof through one opening and then the other. I felt the silky material as it slowly slid up my legs. It came to rest against my new larger rump and hips, before perfectly cupping my new smaller package. I looked down, and I was impressed, it seemed to highlight both my masculine and feminine qualities, hugging every part of me. It was a bit small, but I didn't mind.

I picked up the second part of the set, it was the bra that matched. That same crimson red would have made me stiff in my pants as a teenage stallion from just a peek of it under a shirt. I slipped it on, aware this was a little small now for how large my breasts had become. What was I now? I was too big for a B-cup, so I had to be at least a C, but maybe I was verging on D... I didn't know. I just know they seemed so big now, and they were so sensitive. My bubblegum pink nipples brushed against the silky fabric, and I whimpered as a little tingling pleasure rushed through me.

I struggled with the clasp behind my back, the sports bra had just had Velcro on the side, but this took some figuring out. I'd never done it from this angle... well, I'd not done it from many angles, normally when I got this far with a girl some part of fate would conspire against me and I'd get stopped in my tracks. When I finally got it into place, I looked down at the last item in the box. I picked it up and carried it to the bathroom. I flicked on the lights and looked at myself in the mirror. I blushed. I looked like someone in a Victoria Secret catalog. Everything was a bit tight, but my body looked so feminine now. My adams apple was barely there, I had curves in all the right places, and other than my sheath, I barely had a bulge in the front.

I grabbed out the last item from the box, and I held the sun dress out in front of me. The white cloth had some sunflowers patterned across it. I felt my face redden even more as I slipped it on over my head, and then adjusted my hair and blond mane. I looked at myself, and it felt like... acceptance, maybe? It didn't look like I had for years, but somehow, I knew this was me too. Yes, it wasn't a stallion looking back at me, but that was okay. Despite everything, it was still me. It's just who I was now, and I looked forward to seeing who exactly that was. I put my hand on my belly, and gave it a little rub. I took a deep breath to settle my nerves, then slipped on a pair of shoes over my hooves, and then walked out into the warm night.

===

The air was hot and sticky, the smell of fresh cut wood and pine filled my nose, mixing with the scents of the forest floor that crunched under my hooves. I could see the light on in his cabin, shining out like a lighthouse in the night calling me closer to rocks rather than pushing me away. The closer I got, the more my heart pounded, and my arousal rose. I wondered if this was a good idea, but I'd already come so far. I knew I couldn't stop now.

I made it into the clearing, and I walked up to his door. My slip on shoes didn't make much noise, as I reached up and knocked softly. It was the knock of someone who almost hoped the person inside wouldn't hear them. From inside I could hear the sound of a guitar playing, I couldn't quite make out the tune, but it reminded me of barns and summer nights just like this one. I heard the music stop, and I leaned up against one of the posts on the porch. I crossed my arms in front of my chest, and put on a cocky grin.

I started to realize this was the wrong pose for who I was now. It wasn't right in this moment, and in this place. I changed my posture, I stood up, and I put my paws on my full belly. I turned the cocky look into a hopeful soft one, and I tilted my muzzle down demurely. I could smell his scent now, it was being pushed out of the window by the fan he had there. It was strong, musky, and earthy. It made my mouth water and my throat tingle as it danced across my nose. The pheromones tickled the mare-ish part in my brain.

The door cracked open and the stallion who had haunted my dreams was now standing there. He was mostly naked, his well-defined chest and arm muscles were outlined by his short fur which had a sheen to it from the dim yellow lamp light coming from inside. His shaggy white mane hung down over his forehead a bit, and it was just long enough to make him look rugged and sexy. He was a good four paws taller than me now, so I had to tilt my head to look up at him and his emerald eyes that assessed me. The white on his muzzle was slightly pink, and I wondered if he was blushing or if he was just hot from the night.

"Good evening, Lucas," He said, but when he called me by my name it almost seemed to question it. Like he could tell it didn't fit with the person standing before him.

And it didn't, did it? I wasn't the Lucas I was a few months ago, I'd changed so much, and I no longer fit that purely masculine name.

"Uh, call me Lou," I said.

"Okay, Lou," he said simply, "so what are you doing here?"

"I..." I started, and I squirmed in the heat of his stare. "I need a stallion..."

He didn't instantly respond, he seemed a little shocked, and he looked me over. I could see things flicking through his mind, questions seeming to be answered, and decisions being made. I could smell his scent getting stronger, and I thought I saw his sheath twitch in his shorts.

"Well," he pondered, "every mare does need a stallion. So if I'm your stallion, does that make you my mare?"

I could feel my sheath twitching at that question, and I felt hotter under that dress than I thought I could.

"For tonight?" I asked before looking up at him with a soft hopeful smile, "I could be."

He stepped aside and gestured for me to come inside.

I walked through the door to the cabin, it was a simple one bedroom, with a bathroom off to one side. The bathroom was a bit bougee, since it'd been designed for people who came here on vacation. But the room on the other paw was simple. Exposed whole logs made up the walls, with a large king-sized bed in the center. There was a small writing desk off to one side, a dresser, and there was a closet off to one side.

The door clicked shut behind me, and I turned back to look at Shane. For all the bravado of his statement, I could see some nervousness in him. It was clear that this was new. To be fair it was sort of new for me too, I wasn't too sure how a girl would act in a situation like this. I'd never made it this far with one before striking out, I had porn but that probably wasn't the best place to draw from. I moved in close to him, and I shyly reached out a paw and put it on his bare chest, and I looked up at him.

"If this is too weird for you, I can just..." I began to say, before he gently closed his paw over mine.

"No don't," he said, "I want you here. I've wanted you here for a while, but... I didn't know how to ask." He started, "My gut was telling me that I wanted you with every ounce of who I was, but my head kept telling me you were a stallion, and that I wasn't into guys. I didn't really know who I was anymore, I felt like everything I knew to be true had been wrong."

"Trust me," I said, "I can relate." Which was true. Who I am now isn't the person I was, and I don't think I'd ever be that person again. But that wasn't a bad thing, was it? Life was about changes, and now I was beginning to feel like a piece of a puzzle that had always been missing was starting to click into place.

"So what now?" The shire stallion asked, his fingers lacing through mine as they rubbed through his chest fur.

"Like I said, I am your mare tonight, and in the morning maybe we can figure out together what exactly that means," I said, before leaning up, standing on my tippy-hooves, and nuzzling under his chin. "But tonight," I whispered, "just treat me like you'd treat any mare who came to you with need in her eyes."

He leaned his long head down, and our lips met in a kiss after I said that. I could feel his paws start to roam over my body. He squeezed my soft ass, and he pulled my body into his. I could feel his strong arms wrapped around my soft frame, and I let out a needy little whimper as I felt his sheath start to stir against me. His paws slid up my back, until one of his paws came around and grabbed one of my breasts. I felt my whole body tense as he squeezed it, the nerve endings lighting up in ways I never knew was possible. It made the need just rise in me, and I smelled his scent getting stronger. It made parts of my brain flick on and just cry out in desire. I felt my insides begging for this stallion in front of me with the most primal feeling I'd ever felt. He slid his paw up from my breast to my shoulder, and he slowly worked off the strap of my dress; it fell to puddle on the floor around my hooves.

Shane took a step back, and I saw the desire in his eyes light up as he saw how I was dressed before him. I blushed, and I ran my paws down my sides, and did a little twirl for him, flicking my tail to the side as he saw my rump, and then coming back to face him. I blew a stray lock of hair from my eyes, and I smiled at him.

"Do you like it?" I asked.

"It looks like you were made for it," he said in awe, and I could see his cock pressing against the inside of his shorts now, "It's almost a shame to take it off..."

I giggled, which surprised me, but I continued, and gave a little shake of my hips. "Well, I can always put them back on later."

"And then I just get to take them off again," he said with a lustful tone as he closed the distance between us. He picked me up with ease, my new smaller frame an easy lift for a shire horse like him- even with extra fat I'd gained. He carefully laid me down on his bed, and then he crawled over me. My blond mane draped over the bed beside me, and I looked up at the big strong stallion above me. He leaned down and kissed me again, letting his body press into mine, and being careful of my rounded belly. I felt his cock pulsing hard just like mine used to do, and it was rubbing against the front of my pantie clad bulge. I whimpered with hunger for him. I was sure I was leaking enough to seep right through that silky lace fabric. I squeezed onto him tight, feeling his strong muscles under my touch, feeling them flex and move as he moved above me. He started to kiss his way down my neck, and when he came to my bra strap, he playfully tugged on it with his teeth, letting it snap back into place. Which got a surprised nicker form me, which made him chuckle. He slipped a paw under me, and with a skill I'd never had, he undid the clasp on the bra with one easy movement. He pulled it off, and tossed it to the side.

He lifted his head up, and just looked at my chest in wonder. He hadn't seen it since the day he'd rescued me from that hole, and it'd grown so much since then. He leaned down and grabbed one of the pink caps on those white globes with his flat teeth and he gently teased it. I cried out in pure pleasure. The new nerve endings there making fire explode inside of me. I squeezed onto him tight, my fingers digging into his fur as I tried to hold on. He caressed my nipple with his tongue, making me whimper. His paw stroked my over stretched belly, and then he started to move down. He kissed me along the way, he was so tender and loving towards my stomach as my little foal stirred inside. The stretched fur looked a little pink under the white and chestnut patches as he worked his way down along my body. He slipped off the end of the bed, his hooves resting on the floor now. His paws slid down my sides, and then they rested on the silky panties I'd worn just for him.

I saw him as he paused, and looked down, taking in the sight. I hadn't been able to see under my belly without a mirror in weeks, but I could just imagine him looking at my undefined bulge. He could probably see the wet spot on it, and I watched in amazement as he leaned down and started to nuzzle at it. It tingled, and felt good, but not as much as it would have a few months ago. My cock stirred in my sheath, but it failed to rise. He slowly pulled them off, letting the fabric slide down my soft legs, before tossing them onto the pile with my bra. I stood up on my elbows, and I watched as he slipped off the shorts he'd been wearing and that dappled horse cock came into view. The thick throbbing maleness facing me down, as if it was daring me to not beg for it.

It twitched in the dim lamplight, casting a shadow on those wooden walls. I could smell it now, it drove something in my head wild, that powerful manly scent filled me with a deep-down desire that I knew it would be impossible to resist. "Please," I panted, "breed your mare..."

His nostrils flared, and I could tell he was getting my own scent to course through his system. It wouldn't be as strong as I was when I was in heat, but I'm sure it was still doing something to the stallion. He helped me to the edge of the bed, my rump hanging off it, my tail swishing below us. He ran a paw over my pregnant belly again, leaning down to give it a soft kiss. I wrapped my legs around his waist, and he reached down to rub the head of his unflared stallion cock against my needy hole. It was like a jolt through me as it touched my skin.

"Mmm already nice and wet, such a needy mare," he cooed. "You came to me just in time." He said with a lustful growl, before he slowly pushed forward and he popped into me with ease.

I gasped, my fingers gripping the bed sheets, as sensations I'd never felt before washed over me. This was nothing like the toys, it was like my body was trying to reward me for being the good little brood-mareboi I had become. He was bigger than my toys, so I felt myself stretch in new ways around him. It wasn't like with the doctor's arm, my body seemed to crave him, tightening around that shaft. My ringed muscle ached around him as that hot throbbing stud cock pushed into me, and I adjusted to his girth. I sucked in a breath between my teeth, and I clenched around him. He mumbled something to reassure me, and I let out a deep breath and felt my ring give into him once again.

I bit my lower lip and closed my eyes tight. I felt him grab the backs of my knees, and hold them as he gave a little grunt and thrusted the last few inches of his powerful stallion cock inside of me. I felt those powerful fertile balls slap against my round ass, and I yelped in pure ecstasy.

"You," he panted, "okay?"

"Yes," I squeaked, "please... please... just breed me. Don't hold back. I can take it. I need it." I whimpered, squirming more as I felt my body pulse around that thick shaft inside of me. The toys had never felt like this. The smell he was giving off was driving me crazy. It was the part of the equation I was missing. My body was a machine designed to be bred now. To carry foal after foal. It needed that key... no, that boot, to kick open the door I'd been holding shut and let all of myself finally come rushing out.

Shane snorted and he started to fuck me now. His hips moved back and forth, that thick stallion cock spreading open my warm velvety smooth insides, smashing against that extra sensitive pleasure button. He stroked all those new nerves I had yet to feel. While he bred me, the more he sweated, the more it turned me on. I kept arching my back, and squirming below him as my body tried to cope with all these new sensations. Like the feeling of the medial ring on his stallion cock popping in and out of me as his cock started to flare within me.

I was being bred properly for the first time.

Getting to feel what it was really like to be a mareboi and be used like I was supposed to be.

My belly and breasts shook, bouncing with his every trust. My whole soft body trembled under his onslaught. The more he bred me, the more I could smell my own scent filling the room and seeming to only push him further. I could just imagine how his muscular ass must be flexing, that short shorn fur glistening, as his tail lashed above it and those heavy foal makers swung between his powerful thighs.

That's when I felt it. It slammed into me like a ton of bricks. I shouted out, and I started to cum. Mareboi cream started to gush from my nearly empty sheath, pulse after pulse pushing out over my crotch like a wave. It was so intense. The most powerful orgasm I'd had in my entire life. It was like my body was trying to expel every ounce of cum I had inside of me. I felt it spill over my crotch and onto the sheets. I saw stars, whimpering as he kept riding me, slamming again and again into that sensitive pleasure spot while my insides wrapped tightly around him and squeezed.

He whinnied above me, and he leaned over me. He nickered, and then he bit along the side of my neck. I gasped as that sudden surge of pain mixed with the pleasure, making my whole body tingle as I felt his seed start to flood into me. That virial seed pumping into me from the flared head of his dick, and making me feel whole for the first time. My body shuddered as my belly was pumped even fuller than it already was.

Shane came up and kissed me deeply again, our bodies intertwined, my foal kicking against the inside of my belly, as this stallion made me feel in a way I never thought I could. Yes, I felt euphoric, but... but I also felt right. For the first time in months, I felt truly myself. Who I was supposed to be. It was a feeling I didn't want to go away...
