"But dad, they're my friends!" my little Adrian protested, but I wasn't going to budge on this one.
"I know son, but don't you think you have too many friends like them?"
"What do you mean?"
"Adrian, almost all of your friends are prey species..." I started, feeling the taste of the bullshit I was about to serve up on my tongue.
"What's wrong with herbivores?" he asked, making sure to use the proper word for them. A good kid, and I was proud of him, but I had my reasons for what I was doing...
"Nothing kiddo, they're fine and good, but spending too much time around them could mess up the way you think. You need to spend more time among your own kind to nurture the instincts that will guide you through life. You... you just gotta trust me on this one..." I sad, honestly unable to finish the speech, knowing it was a load of crap. I knew the words all right, because all I had to do was remember my dad saying them to me. Of course he actually believed them, or so I had thought at the time.
The pup was sullen, but not willing to fight me over this, at least not tonight. He might though, since he was pretty mature for a twelve year old. He just brushed his teeth and went to bed, and so did I. The difference was that I knew I would be up around midnight, awaiting my visit with the usual mixture of eager anticipation and barely suppressed shame.
*******
"C'mon bitch, get that tail up..." the voice behind me teased, even though my tail was already up, my shiny pucker exposed to the young ram who was even then messing with me, rubbing the tip of his cock at the shiny ring of muscle without pushing in. The same long shaft that I could still taste on my tongue. Still, I did my best to hike my tail up even further, although I was already on offer, my ass hanging over the arm-rest of the couch with my own steely cock angled downwards.
It was trapped in a heavy-duty canine condom because the place would be a mess otherwise. And it was angled down like this because Ethan liked to watch me fill it. 'Bitch milk', he called it, and not a drop of it would go to waste. If dad was looking down on me right now (or more likely up) he'd have blown a fuse. Hell, anyone would be confused to see a wolf like me bent over for a kid half my age and about two thirds my size.
But bent over I was, my muzzle shut even though I felt like panting, or even begging the ram behind me to stick that hard young shaft under my tail and give me what I need. But I was always worried about waking Adrian up. As the young ram's tip slowly spread me open and that hot, spit-slicked length began to sink into me all I could do was muffle a moan.
"Ngh, there's a tight little bitch..." Ethan groaned as he pushed more of his rod into me, his words making my pucker twitch around him.
He'd certainly gotten cockier over the months we've been doing this, but I have to admit I let him. In fact this was what I wanted - to be a willing, eager bitch to a herbivore. Which is why I gave my son that bullshit lecture earlier. He's a lot like his old man, but I don't want him following in these particular footsteps.
He looks up to me, but then again I'm his only parent. Gina and I got hitched right after graduation, and weren't really trying for a kid yet. I think I managed to talk her into keeping the baby, even though I could tell back then she wasn't ready to be a mom. Maybe she never would have been. Her motherly instincts ran out before Adrian was one year old and so did she - packing up and leaving me with a pup and a note.
I somehow never got back to serious dating, although I had a few numbers I could dial up when I managed to find an over-night sitter, women who weren't ready to tie the knot but eager to take one. I figured I still had time - I was thirty six and kept myself in great shape, which is why I'd been asked to fill in for the coach at my son's school when the coyote got into a fender-bender and had to spend two weeks in bed.
That's where I'd met Ethan. He was on the basketball team I'd been coaching and he seemed to like me, although it was hard to tell because the sixteen year old ram had been a bit nervous around me back then. One time it was just us in the locker room and he'd taken his sweet time getting changed, obviously eager for me to see him naked but desperate to make it seem casual. I don't exactly remember how I'd ended up on my knees with his cock down my throat, but that had been the start of it.
Even after that he was still a bit unsure about the pecking order. After all, I was older, bigger and stronger, and I think he was surprised that despite all that I was willing to be his bitch. Now you're probably thinking I was a closet fag the whole time and that this was the reason my wife left. But it honestly wasn't the case. I love women and the women that I have loved will attest that I love them well. In fact most of them would probably laugh at the idea that the wolf who could make their legs wobble with a low growl and rut them until they couldn't think would ever lift his tail for someone. I know for a fact that a few of them would bite their lip at the thought of me breeding a boy like Ethan, but the other way 'round?
It had only happened once in my whole life, so long ago that I thought it was just a fluke. Matthew had been my next-door neighbor, a rabbit about five years older than me. The coolest person I knew back then, because he'd let me hang out with him even though I was just a kid. I was eleven when suggested a game of 'you show me yours and I'll show you mine'. We'd been up in his room, and I figured there was no harm in it.
So we'd both stroked ourselves until we were out of our sheaths, but then Mat got a little funny. He'd tell me to do things in this strange new tone, like he was expecting me to go along. What surprised me was that I did. He told me to stroke and I stroked. He told me to lick, and I licked until my tongue was sore. He told me to lift my tail and I did, trying to keep it from wagging.
I'd sucked him off a few times before he claimed my ass. He was gentle the first time, but after I'd gotten used to it he would breed my ass like the rabbit he was, hips moving like a sewing machine while I just took it like an eager little bitch. He'd fucked me through dry cums without any of us realizing it until one day I sprayed my first load on his bed sheets as he humped my pliant little butt. That's when I learned I had to wear a condom while getting fucked, because I cum a lot and with my cock bobbing around the stuff gets everywhere.
When Mat left town to go to college some time later that marked the end of what I thought was just a weird hormonal phase. With him gone I tried to push things up there, to get the same feeling but it didn't feel all that great. But then I started noticing girls and came to the shocking discovery that I could also cum by sticking my cock in someone else. With that realization I never thought about another man's junk, until the ram's stood naked in front of me in that locker room. Naked and visibly eager.
"Fuck, you're already milking me! Well I'm glad you're in the mood tonight, 'cause I have a little surprise for you..."
I wasn't sure what he was talking about, too focused on the sensation of his hips grinding against my ass as he bottomed out. I knew I was milking his shaft, my pucker pulsing as the lack of movement combined with the sensation of something hard and hot filling me drove me wild. Nine inches of warm, steely teenage cock twitching and throbbing, the tip of it leaking somewhere deep in my body and lubing me up even more.
I was wondering if he was holding still on purpose. Sometimes he liked to just bottom out and make me beg for it or wriggle back and forth on his length. Truth is I got off on it, but he should know better with my son in the house. When I felt him start to pull out it put my mind at ease, and I just allowed myself to enjoy the sensation of the ram's shaft sliding out of me as the horny teen paced himself before starting to fuck me in earnest.
I felt one hand grip the base of my tail while the other held my hip, and braced myself for what I knew was coming. Sure enough, the moment he'd pulled all but his tip out he reversed his direction, spearing me with his young rod in one brutal thrust. Thankfully my jaw remained clenched and nothing but a muffled grunt got out of it as the thick member suddenly invaded me once again.
He did it the same way a few more times, making sure I was good and loose - pulling out teasingly slow before pushing back into my ass in a split second. He gave my cheek a good hard slap and I winced. Not at the pain which I got off on, but at how loud the sound seemed in the quiet, dimly-lit living room.
The hand stayed on my burning cheek, giving it a grope before the ram's hips began to move again, this time in a steady rhythm. The teasing was over and he was now giving me what I needed from him - a good vigorous fucking. I did my best to relax myself back there so I could more easily take the length of flesh sliding in and out of my lube-slicked ass. But every now and again my pucker would tighten up, clenching around the caprine cock, making both me and Ethan groan at the sensation.
"Don't worry bitch. You'll get what you -ngh! - need soon enough..."
His words sent a shudder through my body, the thrill of it easily overwhelming the shame. I'd learned that I needed more than just a dick up my ass. Submitting to a herbivore, listening to him tease me about what an eager bitch I was as I acted just like one... That was what really got me off and why I did everything I could to keep my son away from 'prey'. After all, if my dad had done a better job of it I never would have taken a rabbit's cock when I was a kid and wouldn't be bent over and stifling moans as a ram used me as his ewe.
Despite the fur muffling it I could hear as well as feel the slaps of Ethan's hard young body against my ass, the teen putting his all into breeding me. I wonder what he got out of it - did he get off on dominating a larger male, and a carnivore to boot, or was he just a kid happy to have an ass he could always burry his bone in. And I knew just how much he was enjoying my ass by the flood of caprine juices leaking into me. Which was just a taste of what was to come...
His sack hung low and slapped against my own, reminding me of how you'd describe a kid Ethan's age - young, dumb and full of cum. At least for now. I have to admit, his nuts were even bigger than mine - elongated and hanging low under his sheath, always on full display. I knew this would end with those nuts pulling up just as the teen reached his climax, shoving himself as deep as he could go before emptying that sack into me.
It was complete and utter submission that did it for me - not only letting a male mount you but actually allowing him to leave his spunk inside the pussy he'd just spent half an hour fucking. He never stuck around after we've finished our thing but he did make sure to admire and comment on my pucker straining to close and keep a fresh load of ram-milk inside.
Fuck, just thinking about it had gotten me steamed up. I felt my insides tensing, and after a few lucky pokes of Ethan's tip against my prostrate I went over the edge. Whimpering noises were escaping my clenched muzzle as I came, my tail-hole pulsing around the ram's still pistoning shaft. 
It always felt different - cumming from getting it in the ass. It wasn't the wild surge that made my cock go off like a fire hose. It seemed to last longer, stoked by the fucking the teen was giving me as my rear-end milked his naked length. My own cock was twitching feebly underneath me and drooling cum rather than sending out powerful jets of it. I knew for a fact that it was deceptive and that I would wind up cumming way more than I did even when I knotted someone, and that the rubber I was wearing would look like a water-balloon by the time this was over.
"Fuck, did you cum already you slut?" Ethan asked, although I could tell by his voice that he was a little out of breath. Either he was winded from the pounding he was giving me or the sensation of my pucker twitching around his cock had him close to the edge.
But if the kid was close to nutting he didn't show it, ramming into me at a steady pace that gave the impression that he could keep going all night. And at that age I knew it wasn't far from the truth. He kept fucking me right through my orgasm and I could feel the condom wrapping my cock swinging with a heavy load of canine spunk, my swollen knot keeping it secure. It never really went down when I had something in my ass.
"Oh, wait a second, I gotta take this..." the ram said, and I could briefly hear a rhythmic buzzing. He kept gripping my tail with one hand, but he'd let go of my hip and I realized he was reaching for his phone. Fucking kids and their smartphones!
"Hey, you here? Yeah, that's the house. Just come in, the door's unlocked, but remember to keep quiet." He said, and my lust fogged mind began to spin. What the fuck was that about? Did he invite someone here? Now?
"Tonight's your lucky night bitch! Remember that fantasy you had about taking a stallion?" he asked, and my ears perked up. A few weeks ago he'd been fucking me in the equipment room in the school gym and had been teasing me and asking me about the cocks I'd taken. A rabbit didn't impress him and he somehow got me talking (well, babbling at that point) about stallions and what I'd like to do with one. He'd been pounding my ass for ten minutes when I started and I guess I got kinda graphic in the heat of the moment. In truth, I had fantasized about horse cocks, but now it seemed Ethan had taken it upon himself to make that fantasy a reality. I winced at the sound of the door opening, but I have to admit my heart skipped a beat at the (thankfully) soft tread of hooves.
"Whoa, I guess you started without me..." same a voice, quiet enough but still louder than I'd like it. Sounded deep but by the tone I guessed it was someone Ethan's age. Considering which part of me was pointed towards the door, I couldn't really tell.
"Well, I gotta get this bitch loose and sloppy if he's going to take what you're packing..." the ram replied, once again pounding into me.
"Yeah, damn if he isn't a proper bitch..." the colt said, walking in front of me. He looked familiar - a sixteen year old palomino with a cream coat and white mane, smirking as he took in the sight of me. He was bigger than Ethan, almost my size, and was obviously wondering at how easy it would be for him to handle me if I was this submissive for someone smaller than I am.
"Now, here's the deal..." he said, looking down at me while I tried to keep my eyes of the swelling in the front of his pants. "I gave Ethan my word to keep this secret no matter what. If you've got cold feet I'll leave, but I'd do a better job of keeping this little secret if I had a personal reason to. After all, I wouldn't want everyone to know I was fucking some faggy daddy-wolf, just like I'm sure you wouldn't like it known you've been raising your tail for horny teens like us right?"
I just gave him a quick nod, since Ethan was really pounding me now. I'm not sure if he was close or just showing off in front of his friend. The colt didn't seem to need more encouragement and he immediately started taking his clothes off. He wasn't wearing much - just shorts and a t-shirt and a few seconds later I was drinking in the sight of the young stallion as his pink length began to drop.
He placed one knee on the couch and the moment I saw him nudging his crotch closer to me my mouth opened wide, longue lolling out while my eyes took in the sight of the biggest cock I'd seen in my life. I was expecting to get my first taste as well, but the colt just lifted the still floppy length and dropped it on top of my head.
"Don't worry bitch, I'm gonna feed you eventually..." he said, obviously enjoying and hardly believing that a grown man like me would take this so willingly.
I couldn't help it. I could feel the weight of the stiffening shaft on top of my head, while the thick base and the stallion's massive sack filled my vision. His balls were handing low and heavy, full of equine spunk that would end up inside me by the time these two left. Just the thought of it made my pucker twitch and I stifled a moan as my ring contracting around the ramming ram made his own smooth shaft seem all the thicker.
The colt in front of me let his shaft slide from the top of my head and I could feel the massive length stroking against my cheek, almost but not quite hard as the equine male grinned down at me. Holding the pink shaft by the base he gave me a slap with the meaty rod before putting his hand on my head and guiding the tip to my muzzle.
My mouth opened on reflex, wide at first and then wider still as I realized just how girthy the colt's member was. My nostrils were flaring, my breath already rapid from the fierce fucking the ram was giving me was now becoming labored, every huff of air filled with the scent of a horny young stallion. I did my best to keep my teeth out of the way as I stuck my tongue out, trying to make room in my muzzle for the mammoth cock being slowly pushed in. I could feel the colt slowly pushing me down, more and more of the fleshy rod sliding along my tongue until the flared tip was hitting the back of my throat. I could usually deep throat Ethan, at least for a while, but it soon became apparent I wouldn't be able to take this beast down my gullet. Instead I gripped the rest of his shaft, my hand barely closing around the thick base as I began to stroke and squeeze the fleshy length.
I moaned as I suckled and slurped messily around the equine shaft as the ram continued to rut me. He was pumping away with such speed that I could no longer tell when he was sliding in or out. There was just the friction of his slick length as it pistoned my pucker and the sensation of the teen's cock battering away at my prostate.
I could tell he was close by the way he kept grunting, yanking on my tail and digging the thumb of his other hand into my cheek, spreading me wide as he savored the sight of my pucker straining around his cock. I'd lost track of how long it had lasted, coming to only when I could no longer feel his sack hitting mine with every thrust.
I could imagine those heavy nuts pulling up tight against the ram's crotch as the rutting teen prepared to shoot his load into the canine bitch wrapped around his cock. Without even thinking my hand slid along the colt's length until it reached his own pouch. A shudder ran through my body as I felt the weight of those orbs in my paw, and the fact that a hand that could easily palm a basketball could barely cup the stallion's sack.
"Ung, here it comes, bitch..." Ethan growled out just before giving one last thrust, sharp enough to push the colt's flare against the back of my throat.
He kept violently grinding his hips into my ass just as the caprine shaft hilted inside me came to life. The first few twitches were dry, the muscles in the young ram's body straining to pump out what I knew would be a massive load. I flicked my ears back on instinct, my eyes loosing focus as all of my attention shifted to what was about to happen inside me.
The equine cock stuffed into my muzzle failed to mask just how whorish my moan was when I felt the first swell of heat in my well-stuffed ass, my pucker pulsing and flexing, milking the young ram as dutifully as any bitch would. I could feel jet after jet blasting into me, my boy eagerly accepting the teen's load until the rush of ram-cum became too much for me to handle. I could hear it squirting out around the shaft sheathed in me, thick, hot trickles running down to soak the soft fuzz covering my own sack. 
I hadn't noticed when Ethan's hand had left my cheek, my mind swimming in the almost drunken haze that being bred always brought on. I did feel it when it landed with a smack back on my ass, the ram chuckling as he groped the stinging cheek. I didn't care. My eyes had focused again, and with the colt's massive sack filling both my vision and my paw, I could only imagine the soft of mess he would leave inside me.
"Finally!" the colt said as a panting Ethan slowly pulled his till stiff cock from my ass. "I was sure the bitch would suck me dry by the time you blew your wad..."
I clenched mu pucker as the ram's tip slipped out, straining to keep the mess he'd pumped inside me on instinct. I released the colt's sack when he began to pull his steely tight from my muzzle, the ache in my jaw making me realize just how wide I'd been forced to open my mouth to take the beast. The knowledge that soon an altogether different part of me would be stretched around it filled me with some trepidation, but I was too far gone to even consider backing out. I had been close to another orgasm when Ethan had pulled out, and felt desperate to once again feel a male forcing his throbbing length under my tail.
"All right, your turn big guy..." the ram said and I could feel him wiping his no doubt messy shaft on one of my furry cheeks. I didn't pay it too much attention, my eyes focused on the steely length the colt was sporting, wondering if I might have bitten off more than I could chew.
"Just like that, huh?" the young stallion said, looking eager as he circled around and took Ethan's position behind me. A second or two later I felt two strong thumbs digging between my cheeks before forcefully stretching them apart. "Hot damn, look at this bitch! Well, at least I'm not gonna need any lube..." he remarked as a dribble of hot caprine spunk leaked from my stretched pucker and down my heavy sack. There was no way I could clench my ass shut with the colt stretching it open, and I felt a familiar shameful thrill as the teen examined my well-bred behind.
I hadn't even noticed when one of the thumbs was removed, and failed to stifle a gasp when I felt what could only be the colt's blunt cockhead prodding against my dripping orifice. My eyes were blank as I focused on the sensation of the silky yet rock hard member pushing under my tail, the trumpet-like head slipping in the ram's mess even while the colt tried to guide it under my tail. I could imagine a strong hand wrapped around the shaft just under the flare, trying to push the blunt tip in through the mess leaking out of me now that my pucker was being spread.
"Hey, can you help me out?" the colt said, and I wasn't sure what he meant or who he was talking to. Ethan seemed quicker on the uptake, and I could soon feel the ram's hand on my other cheek, the two teens prying me open as wide as they could so that the stallion cold push himself inside me. I did my best tor relax, taking deep and shaky breaths as I felt my hole stretch around the biggest thing that had ever tried to force its way into my ass. It hurt even more than losing my virginity did all those years ago and I was starting to think this was a really bad idea. And then the flare slipped inside me.
"Ungghhh, fuck!" the colt grunted out, too loud for my liking, but I didn't dare open my mouth to silence him. My cock was twitching along with my pucker and it was all I could do to keep myself from moaning. My ring still stung as the equine rod kept it pried open, but the mere tip of the colt's cock already had me feeling stuffed, and there was about another foot of equine flesh still to come.
"Why'd you stop?" I heard Ethan ask from behind me, giving my cheek one more squeeze before releasing it now that the stallion's tip was securely lodged within me.
"Need a- ngh!- moment..."
"Holy shit, don't tell me it's your first time getting some ass!?"
"Hey, if you had a cock like mine you'd know how hard it is to get a girl to spread her cheeks..." the young horse replied, and I could feel him push another inch or so into me.
I failed to suppress a groan as the rim of his flare pushed against my prostate and almost pushed me over. I panted out my nose, my jaw still clenched shut as the colt began to claim my rear. His throbbing length was snaking its way inside me, sliding in easily thanks to the mess the ram had made of my ass. Part of Ethan's load was being pushed deeper inside me but some of it managed to leak out around the equine shaft despite how tightly my pucker clung to the mottled length. I could feel some of it soaking into the sparse fur covering my sack while the rest dripped down as the stallion made room in me for what those hefty nuts of his were preparing to unload.
It was all I could do not to moan out loud as the stallion's sock continued to conquer me, pushing slowly but going deeper than even the ram's impressive length ever managed to reach. I'd never felt so full in my life and the amount of equine flesh being pushed under my tail seemed endless, inch after throbbing inch rubbing every sensitive spot inside me and finding a few I never knew I had. I actually whined when I felt the medial ring pushing and then popping past my ring, and almost came when the same ridge rubbed against my prostate.
"Ungh, there we go!" the colt behind me almost growled when his hips pressed against my ass, the equine fucker buried to the hilt under my tail. He squeezed my cheek with one hand, and as his fingers dug in I could feel my pucker squeezing the monstrous shaft penetrating it in return. One large hand stayed on my ass while the other one tightened around the base of my tail, the firm mating grip enough to make my heart flutter and my sack twitch. Just having the stallion's cock inside me was keeping me on the edge, my body wrapped so tight around the equine member that I could feel the colt's heartbeat inside me.
"Did I miss anything?" Ethan asked, coming out of the bathroom and I only then realized I hadn't even noticed he'd been gone. My eyes had stared blankly while my mind focused entirely on the stallion's conquest of my rear.
"Nah, the fun's only starting..." he said, and I felt my eyes actually roll up as he began to pull out. I could feel every ridge and vein on the steely length as my pucker clung to its velvety surface, my mind conjuring the vision of my ring spread taut around the mottled spire of horse-meat now glistening under a thin milky layer of the ram's spunk.
As slow as the colt's withdrawal had been, his thrust was anything but. He'd only pulled half his cock from my ass before reversing direction and once again spearing me on his twitching member, forcing a yelp from my throat. My cheeks burned as I heard the sound I'd last let out the first time a rabbit had started pumping my behind, giving me the first fucking of my life. And despite the fact that I was older and bigger than the teen now breeding my rear, at that moment I felt entirely owned by the colt, a willing slut lifting his tail and whimpering as he gave me the fucking I was obviously desperate for.
"Now who's making too much noise?" Ethan chided me before kneeling on the couch just in front of my face. I could see a few inches of pink poking out of his sheath, the young ram obviously enjoying the sight of me taking my first ever horse-cock. Even before he put his hand on the back of my head my muzzle was already parting as I took his member into my mouth. The familiar taste and smell of the young caprine filled my nose once it came to rest against the pale fur of his crotch, my lips brushing against his sheath as he began to hump into my muzzle.
I was glad for the ram's length slowly filling my mouth, since I wasn't sure if I could have kept quiet without it. The colt behind me had settled into a steady rhythm, and I could imagine his hips moving as the lengthy equine member pistoned in and out of me, my ears filled with the squelching noises of my ass being speared over and over, the stallion's firm grip on my tail keeping me exposed. Being young he didn't have much of a technique, but he was fucking me with that vigor that made me feel that if I passed out he'd still be rutting me by the time I came to.
"So - ugh! - this is the guy that's talking all that shit about 'prey' species?" the colt asked, a smirk evident in his tone and justifiably so, since I was letting myself get fucked by prey and obviously enjoying every second of it.
"Yeah, but that's just some BS he feeds his kid. He's worried about junior ending up like this..."
"Fuck man, that's messed up!" the colt chortled, and I could only imagine how he saw it - a man raising his tail and moaning as another male fucked his ass worried his son might end up doing the same...
"I thought so too, but I think he's got good reason to be worried..." the ram replied and my eyes shot up, struggling to focus on his face as the colt continued to breed my ass. "Oh yeah, I guess I haven't told you about that..." Ethan began once his eyes met mine, his hand never leaving the top of my head as he pushed me down on his emerging length even as he spoke. "Turns out your little Adrian and my cousin Matt are classmates. I only made the connection last week when I was over there and he complained how he's got this wolf friend whose dad has a problem with him being friends with 'prey'."
"Heh, small world huh?"
"Yeah, he told me the two of them had been getting kinda curious - seeing whose is bigger and even stroking each other once." The ram said, never once slowing down as he fucked my muzzle. I tensed up at his words and the image of my son going down the same path that led me here, but that only made the feeling of the equine shaft pummeling my ass all the more intense.
"Guess the apple doesn't fall far from the three, huh?" the colt behind me said, panting as he continued to rut me with everything he had.
"Well we'll see about that. I gave Matt a little hint that his friend might give him a little more if he asked. I figure the next time they meet the pup will get his first taste of ram-spunk and probably give up his cherry in a month's time."
Despite the fact that my worst fears were being confirmed it was getting harder for me to care. My word seemed to narrow down to the heat coming from underneath my tail and the rock-hard length of stallion meat causing it, as well as the taste of the ram's cock leaking in my muzzle. I could feel my own shaft swimming in my spunk, the condom hanging from my knot as the mess that Ethan had left in me dripped down my sack.
The young stallion had shortened his thrusts and as a result his medial ring was pummeling my prostate as he bred me like a jackhammer. I was doing my best to relax to accommodate the savage pace, but try as I might I was stretched to my limits around the colt's girth, my moans and grunts muffled by the caprine cock now reaching the back of my throat every time Ethan pressed my muzzle to his furry sheath.
The sensations were intense, but it was the knowledge that I was letting myself be used like a sex-toy by these two teens that pushed me over the edge. I could feel my ass slowly tighten just as my balls pulled up and then begin to clench like mad when the tip of my cock finally erupted, filling the condom with my second load.
"Ugghh, fuck! I think the bitch just came!" the colt behind me grunted, obviously close to his own climax, especially with my ass milking him as shamelessly as any mare would.
Ethan had said something back to him but I didn't catch it. With my ass pulsing around the horsecock pistoning in and out of it, the already massive tool felt twice as thick. My nostrils were flaring as I tried to breathe around the cock the young ram was pushing deeper down my gullet, but I didn't dare try and pull off, not trusting myself to muffle noises I definitely didn't want Adrian to hear.
My cock was still spurting when I felt the strange new sensation of the colt's cock growing inside me. Even though I knew what was coming I wasn't prepared for the pain as the bell-like tip mushroomed up deeper in me than anything had ever been, stopping just short of splitting me open. The young stallion was still hammering away at my ass, his hand a vise around my tail while he rode me like a cheap whore. A second or two later and I could no longer feel those heavy equine nuts slapping against my own whenever he hilted himself up my slick pucker.
He kept pumping me for a few more second until he finally drove his cock as deep inside me as he could, pulling back on my tail as the monster buried up my ass began to swell. The first pulse was so strong I could actually feel it inside me as it shot out, a surge of equine essence forcing its way deeper into my body. The colt kept grinding against me as he hosed my insides, my ass clenching hard around him and forcing my prostate up against the throbbing rod.
I was apparently too focused on what was happening behind me to realize Ethan was at the end of his rope as well. He startled me by pushing himself as deep as he could, until the tip of his cock was in my throat and my lips were pressed against his sheath. I almost sputtered when he blasted his own load down my gullet, feeling the ram's hand stroking my throat and getting me to swallow. I soon started doing just that and I heard him hiss as my throat tightened around his erupting tip, massaging his cock as he unloaded his nuts down my gullet.
Even though the stallion had blown first, he was still shooting by the time Ethan began to pull his slimy length from my muzzle, but that might have been because the ram had just left a load up my ass minutes before. My pucker was wrapped so tight around the colt's cock that not a drop escaped, the teen staying buried to the hilt until that monster between his legs began to soften.
"There's a good mare..." he almost growled as he pulled his sensitive cock form my straining rear.
I would feel my pucker cling to the veiny length, my eyes almost rolling back in my head as more than a foot of equine flesh was slowly pulled from my body. I could feel myself being stretched little further as the colt struggled to pull a still swollen flare from my ass, and I flicked my ears back at the sound of his cum pouring from my well-bred opening one he finally managed to pop it out. Fuck, that towel I'd put down could handle one or two of Ethan's loads, but the river of stallion milk dripping from my tail-hole would soak through it...
"Fuck man, just look at this mess..." I heard him mutter, and wondered what he was seeing. I'd been a mess even before he'd emptied his nuts in my ass and I still couldn't clench my pucker shut after the drilling he'd given me.
"Yeah, but check this out..."
That was Ethan's voice, and I realized the ram was no longer in front of me. Soon I felt him fiddling with the condom I'd filled up, and a good thing too because after cumming twice and nothing up my ass my knot was finally starting to go down. I felt him careful pull the thick rim over the swollen bulb and pull the well filled rubber of my cock.
"Will you look at that! And I figured since he was lifting his tail for us that his junk was just for show..."
"Nah, here's the show..." Ethan replied and I could see him walking up to me with the condom that looked more like a water-balloon. 
I was still panting like a bitch in heat, which I don't doubt is how I looked to the two teens, when Ethan put his hand under my muzzle and tilted my head up. I knew what he wanted even before he dangled the thing over me and brought the nipple-like tip to my lips. I let it slip between my saw-like front teeth and started to move them side to side, tearing at the silicone until it gave way and I felt a torrent of my own still warm cum fill my mouth. 
It was slimy and bitter and doing this for a crowd was demeaning as hell, but in my present state it was just what I needed. I struggled to keep up with the flood of puppy-juice, and when the rubber was finally drained I found myself gasping for breath, panting like a bitch with my ass up in the air and my tail still hiked away from the mess under it. Since the show was over the two quickly got dressed and I groggily waved them goodbye, waiting for feeling to return to my legs before I got up and cleaned everyth...
"D-Dad?"
The words hit me like a taser and the moment I whipped my head up my eyes met my son's. I've always dreaded the thought of him seeing me like this - naked and obviously used. It might sound crazy, but I wished there was revulsion, shock or fear in his eyes. But as he took in the sight of me, the expression was of a strange sort of awe, one I imagine I must have worn as the first time I parted my muzzle and prepared to take a rabbit's cock in my mouth.
My hopes sank entirely at the sight of the slight tent in his pajama bottoms. The apple didn't fall far enough from the tree for my liking, and I knew from personal experience there was no fighting nature. It was only a matter of time before my son lifted his tail for his little friend, and after he'd seen me like this what could I possibly say to make him think he shouldn't?
