“Uh…wow.”
One glance around the warm, dimly lit room, and the gravity of my situation hit me all at once. I’d been talking to Rex online for years now. And it had taken years for casual horny roleplay to turn into small talk to turn into full-on conversations in which I’d actually been granted any information about this guy’s real life. And here I was, in his house. Not just his house, but in this room. The one we’d talked so much about.
“You like it?” Rex’s voice had this little hint of smugness. He knew my answer.
Slowly my gaze swept around the walls, taking it all in. Huge framed photographic prints adorned the room, images of men’s asses in tight underwear…with tails sticking out. I’d seen some of these photos before, online. And I also recognized the nicely arranged display of faux costume tails. Relics from another time. Rex didn’t really need those anymore.
One wall was filled mostly by a massive full-length mirror. There were warm lights all around, some cushions on the floor. A dark wooden dresser with a row of vials perched neatly atop.
My eyes darted back to one of the framed photos. I stared at the hole in the man’s red underwear, admiring the strong, thick leopard tail curling out behind him.
“Like it? I’m getting hard just being in here,” I confessed. Rex laughed.
“Check it out,” he said, opening one of the dresser drawers. “I’ve got any kind of fabric, any kind of shorts or underwear you could possibly wanna sprout through. Gotta keep a good stock cuz I keep rippin’ em.” He chuckled to himself as I came forward and peered inside.
Indeed, all sorts of garments were folded neatly in the drawer, multiple pairs of each type. I stared, considering the merits of all the options. My cock twitched as I imagined a thick tail busting through each variety of fabric.
Rex was already picking up vials from the top of the dresser, expertly drawing their contents into a syringe. “I think today…I’m gonna grow a dog tail. Nice thick labrador type.”
Snapping out of my fabric fantasies, I felt another twinge down below as I imagined a stiff, rudderlike dog tail sticking out from Rex’s ass, having torn a perfect hole through his underwear. “Oh…that’s gonna be so sexy…”
I scanned the row of vials. I couldn’t believe I’d really been invited here…that I really had access to this technology. Few did - and fewer shared their results online. Rex was very popular in the chats for the photos and videos he shared of himself sprouting real, actual tails. I knew I was lucky…all those other guys would kill to be here, to be as close to Rex as I was.
Despite our closeness, he was a pretty vague, secretive sort of guy. Honestly, I still didn’t have the clearest idea of what he did for a living; what allowed him the luxury of affording these drugs. Something in tech? I don’t know, it always kind of went over my head. I got the sense he didn’t want me to know. All that really mattered was we got along…and we both shared the most intense, overwhelming tail fetish.
“What about you, man? What’ll it be?” Rex sat his syringe down and stared at me, his eyes shining with eagerness.
I was sure he already knew the answer, but breathlessly, I said it anyway. “Bull.”
My greatest fantasy. Those long, strong tails, with those massive, thick tassels of hair hanging off the end…oh, to have one sticking out of my back, to feel it violently swishing behind me…
Rex laughed. He was staring at my crotch. “I see you’re excited about this.”
“Oh, fuck off!” I averted my eyes, chuckling. Yeah, I was rock hard and it was plainly obvious.
Rex kept smiling as he got to work drawing up my drugs. “Alright, so I’m gonna inject this sub-Q. Should take anywhere from fifteen to twenty minutes to start taking effect. Why don’t you pick your poison?” He gestured to the open drawer.
I’d already made up my mind: lycra. I wanted something stretchy, so I could watch my tailbulge grow as tall and tight as possible. I told Rex my decision, and he nodded approvingly, pulling out a red pair from the drawer. “Check this out,” he announced, turning the back side of the briefs towards me. I noticed a strange, sagging shape to the fabric.
“Most of the stuff in this drawer…I had ‘em modified. See this little floppy part in the back? ‘S a pouch. More room for your tail to grow. Makes it last longer…makes for some real big bulges.” My dick twitched at the thought. Rex tossed me the underwear. “Get changed and I’ll inject you.”
——
Rex and I sat on the floor across from one another, reclining against the cushions. To my right was the massive mirror, promising an excellent view of our impending tail growth. The injection had been essentially painless, and now, with me clad in my red lycra briefs, and Rex in a white cotton pair, all that was left was to wait.
Considering what a bizarre - and hot - situation we were in, I was surprised at how natural it felt to just lay back and shoot the shit as we relaxed. I lost track of time as we talked about mutual friends we’d known online over the years. A little bit of work stuff. Porn we’d both jerked off to. That kind of thing. We reminisced about one really annoying guy we’d needed to kick out of a group chat, and soon we were just about keeling over laughing as we recounted some of the stuff he’d done.
Suddenly, there was a pause in the raucous laughter; a sort of knowing look coming over Rex’s face. He grunted, turning to look behind himself.
“Oh…. OHHH! ‘ere it comes… ohhh man…” Rex groaned, bending low and stretching his briefs over his ass. I could see it - a tiny lump swelling to life under the fabric. “Ohh man, every time…it feels so damn good!”
My cock was absolutely throbbing. I couldn’t believe what I was seeing. Right before my eyes, my greatest fantasies were coming true. Rex was doubled over in sheer ecstasy, wiggling his ass and convulsing in pleasure, the lump in his underwear steadily pushing out further and further.
“Ohhh GOD… my tail…I’m….I’m growin’ a big ole dog tail! AHHH fuck! I got a tail!” Rex shoved his expanding bulge into the air. The fabric outlined it perfectly, revealing every little throb and twitch.
“Oh Rex…oh my god, man, it’s so sexy…look at it bobbin’ around when you move…aw fuck, aw FUCK!” I felt like I might cum just looking at it! I remembered the first time I’d seen one of Rex’s videos…I just about did cream myself.
Just as I was peering down and noticing the wet spot of pre seeping into my red underwear, I felt an erotic swelling of pleasure at the small of my back. My jaw fell open, my breathing grew heavy. It was happening. Oh my god, it was really happening.
“I feel it, man! It’s coming, oh fuck!” I kneeled down low, turning to peer into the wall mirror. I could see it, pushing into the little pouch in the back of the underwear. A tiny, twitching nub, growing steadily longer.
Suddenly it throbbed hard and surged forward, pressing into the fabric with full force. “AUUGHH! Oh FUCK, dude!” My cock pulsed, shooting precum. “It just had a fuckin’ growth spurt or something! OHHH, GOD, that feels awesome!” I bent as low as I could, stretching the fabric over my tail-nub.
Rex had been hard at work bending and moaning just like me, lost in the pleasure. His growing dog tail had created a huge tent behind him, and through the white fabric, I could plainly see it twitching from side to side. He managed to snap out of it and look over, a broad smile sweeping across his face. “Fuck yeah, man! Grow that tail! Gonna be a long, sexy bull’s tail stickin’ out of those underwear!”
I moaned again at his words, savoring the erotic pulsations of my growing tail. Its growth was slow but steady, the pouch in my underwear filling up little by little, the fabric tightening increasingly. There were no words to describe how good it felt, how stiff my cock was. I had my eyes shut, taking it all in.
Then, I felt something collide with my tailbulge and my eyes shot open. “AUUUGHH! FUCK! FUUUUuuCCKK!” My gaze went to the full-length mirror. Rex, still on his knees, had backed up and shoved his tailbulge right into mine. He was whining and moaning, wiggling his butt so that his thick, stiff dog tail-tent was rubbing right up against my own expanding bulge! I’d never felt anything close to this before.
Groaning, I shoved my ass back into his, our twitching bulges grinding forcefully into each other. “Ahhh fuck, man…my tail feels so good rubbin’ on yours like that! Fuck, don’t stop!”
Rex let out a doglike whine. “Hell no, I ain’t stopping…feels too damn good…mm, your tail’s so stiff! Feels awesome against mine! Ahh fuck, I love growin’ a big…thick…sexy tail! Can’t wait to feel this thing…mmmff…bust outta my briefs!”
I moaned uncontrollably. “I-I…I’m really…sproutin’ a big long bull tail! And it feels so good! So FUCKING good! Aww man, I’m so hard! My cock’s rock hard!”
Rex’s tail-tent was incredibly thick now, and a good six inches long. It was filling up the pouch in his briefs, and hesitantly rocking from side-to-side. Seeing it in the mirror, pressed up against my own bulge…it was the hottest thing imaginable! Rex’s tail jerked and he groaned. “Ahh fuck man, my tail…it’s tryna wag…aww fuck, gonna wag this thing so damn hard when it bursts…gotta…WAG! Ohh, fuck, man, I gotta WAG! Gotta wag my big…thick…TAIL! AUUUGHH!”
His tail grew longer, straining the fabric, jutting out obscenely as he bent lower and kept grinding into mine. The thought of that labrador tail busting out and wagging made my cock twitch and squirt pre.
Rex shoved his bulge into mine one last time, then crawled forward and reached his hand back. He began to rub and squeeze his tail, huffing and moaning as he did so. “Ya gotta try this,” he urged me. “Just…try rubbin’ it all over. See where it feels best. Mmm…fuuuck…”
It was hard to peel my eyes away from Rex’s hand caressing his big, bobbing tail-tent…but I switched focus to my own stiff, erect tail. It was pushing the limits of the lycra fabric, but still contained entirely within the tail-pouch. It stood straight up in the air, easily seven inches long. I reached my hand back and squeezed, then began to stroke my tail as though it was my cock. “Awww god..oh, fuck, that’s good! OH!” I kept stroking, then tried wrapping my hand around the base of my tail and giving it a little tug. It felt amazing. I stroked upwards, stopping at the tip of my growing tail, and used a couple fingers to tease and rub the very end that was pressing into the fabric.
“AUUUGH! OH! FUCK!” Wow. Yeah, that felt REALLY good. I kept playing with my tailtip, squirting pre and causing my tail-bulge to jerk in pleasure. “Ahhhh…ohhh, man, it’s…it’s the tailtip for me,” I moaned to Rex. “My tail is so sensitive right there…” I kept rubbing and my tail seemed to respond, surging forward, the already taut tent straining harder. It felt so tight, and it was incredible. I could feel the pressure from the fabric against my tailtip, all the way down to my thick tailbase. I stared in the mirror, taking in the incredible sight of my rigid, long tail pushing the limits of the red lycra.
“Ahh yeah…keep rubbin’, it’ll make your tail push harder…ohhhHHH!” Rex was hard at work squeezing his tailbase, his massive tail-tent visibly jerking from side to side. “Doesn’t it feel…mmm…awesome? Feelin’ your tail..throb…and get longer? Mine feels fuckin’ HUGE…got such a big fuckin’ tail…”
“Ohh god…are you kiddin’ me? Feels…feels SO good!” I moaned, playing with my long, stiff tent. “I…I’m really growin’ a TAIL! Makes my cock twitch just sayin’ that! A TAIL! I have a TAIL! I’m growin’ a TAIL!” I was drenching myself in pre. I couldn’t resist anymore. I had to start rubbing my cock through my briefs.
Rex gave a joyous laugh. “That’s right!” He gave his tail a few more strokes before planting both hands on the ground and bending steeply, ass high in the air. His now massive tailbulge was jerking back and forth furiously, trying with all its might to wag, but finding its fluidity of motion was hindered by the friction of the painfully tight fabric. He panted and moaned, fabric creaking as he grew even more tail. “Ahh…it’s getting so tight…there’s so much pressure! My tail’s gettin’ too huge for my briefs! Ohh god!” The waistband of his briefs was beginning to be pulled away from his body, so long was his tail. “Ohhh fuck…I think…it’s gonna split the fabric soon! Think I’m close…to sprouting! Ohhh fuck! Agghh! My… tail…”
“C’mon Rex! Sprout it! SPROUT it!” My heart was beating rapidfire, my sight fixated on the tented underwear. I couldn’t stop absentmindedly rubbing my stiff and leaky cock through the fabric. More than I’d ever needed anything, I needed to see Rex unleash his tail. In front of me, in the flesh…a real guy sprouting a real tail!
Rex seemed to have lost any ability to form coherent words, instead letting loose an endless stream of erotic grunts and moans and wails as he wagged his ass and pushed his twitching tailbulge out with all his might. I could hear seams splitting. He shoved his ass violently skyward. “Ahhh…. aaauuughh…”
SHRRRPP
A small tear formed at the tip of his tailbulge, shiny black fur poking through. The whole throbbing mass wagged harder as Rex bent steeply and pushed again. “OhhhHHH!! AAAAUU GOD!!”
SHRRRRPPPP
Another set of seams popped, more fur revealing itself. It was evident the briefs couldn’t hold on. I could see threads being pulled apart, fabric being stretched to its limit. Rex’s pleasured groans were defeaning as he convulsed, his ass bobbing about frantically. And then, in a flash, it happened. He shoved his ass out, and an immense POP echoed through the room as his briefs pratically exploded, shreds of fabric scattering like shrapnel in all directions, a tall, thick, rudderlike labrador tail now standing erect behind him. It was only for a split second that I was even able to admire the size and shape of that strong black tail, because instantaneously, it erupted into a crazed fit of wagging. Rex had already long ago lost his mind with pleasure, but it was evident his wagging had increased it tenfold as almost horrifically loud and inhuman howls and moans exploded from his throat, finally giving way to English speech once again.
“I HAVE A TAIL! I HAVE A TAIL!” His screams were crazed, feral. “WAGGIN’ my FUCKIN’ tail! I GOTTA WAG! I NEED IT! Oh, FUCK, oh GOD! Lemme WAG! Feels so FUCKING GOOD!”
I was breathless. And with all my focus directed at that stiff, hairy tail of his, I hadn’t even noticed Rex’s cock. His rigid member was spasming, squirting cum like a firehose handsfree across the room, puddles visibly beginning to pool on the cool floor. It seemed endless - each mighty thrash of his tail triggered another ejection, and finally he managed to wrap a trembling hand around his turgid cock, desperately jerking himself.
I was beet red, my heart beating out of my chest, my eyes unblinking as I watched. My pulsing cock strained urgently against my underwear, soaking them with spurts of pre. I felt the deepest, most carnal arousal of my life, my cock practically begging to be rubbed, to be allowed to shoot hot cum like Rex’s. And my tail…it was straining violently, twitching, pulling the fabric tight against my erection. I knew it was going to give out soon. The pressure was unbelievable. I took a deep breath and gave my desperate cock a squeeze through the red lycra, then bent down, wagging my ass.
I groaned deeply, sweat pouring down my skin. I grunted, shutting my eyes, and shoved my ass as high as I could. My compressed tail was beginning to jerk violently from side to side, stretching the lycra to its limits. It felt so good, but I wanted more. I wanted to feel my tail burst! I wanted it more than anything!
“Come ON…” I whined, “Sprout already! Bust outta there! Need to feel my long…sexy bull tail…whippin’ around back there…mmmmfff…come ONNN…”
The fabric creaked, the pleasure building. I was moaning shamefully loud, my big tailbulge stretching tall as I rocked from side to side, writhing my body in desperation. Finally, I felt the first stitch give out. Time seemed to stand still as the seams creaked and stretched. And then, so fast I could barely register it…
shhRRRRRPPPPP!
PSSHHHHEWWWW!
A perfect hole was busted through the red lycra as my bull tail shot violently into the world, standing up stiffly behind me and rapidly gaining feet of length. My eyes darted to the mirror, and I saw it - a long, muscular, ropey brown tail sticking straight out behind me, a dark and long tuft of wiry, wavy hair sprouting from its tip. And then, just as quickly as it had burst, it began to swish, and then full-on swat.
My cock pulsed. I moaned ecstastically. “Ohhh FUCK! OH GOD!” Wildly, my tail was swatting away imaginary flies. The torn fabric hugged the thick tailbase, and waves of almost torturously divine pleasure radiated from each muscle of my new appendage as it moved violently, sweeping from side to side and whacking my legs and ribs as it swung heavily. I watched in the mirror, my eyes wide as dinner plates as I took it in. The shape of my tail, its motions, the weight of the switch at the end of my tail and the way that long hair felt grazing my skin…
“Ohh god…got…a tail! Rex! Rex, I’ve got a bull tail! I’m waggin’ my fuckin’ tail! My LONG tail! Oh god, it’s so long…OHHH!”
I thrusted my hips, my cock throbbed, and I felt my inevitable orgasm coming rapidly closer. With a mighty thwack of my tail and an earsplitting moan, my cock began to squirt, drenching the red lycra with hot cum!
Desperately, I fumbled with the underwear, forcing them as far down as my knees and shuddering at the feeling of my tail slipping free from the hole it had created. Now my rigid cock was free, and it was STILL spurting! It bobbed and jerked as ropes of white cum shot across the room. Breathing hard, I brought my hand to my member and began pulling at myself, milking more and more. I shuddered, taking a deep breath. I needed to stroke my cock more than anything, and it felt so good. So, so good. My cock felt so big and so hard, and my endless orgasm continued. Rope after rope, pooling on the floor.
Rex was just beginning to snap out of his own ecstasy. Breathing hard, he managed to turn towards me and see my long tail for himself. “Lookit that sexy bull’s tail sticking outta you! Mmm, god, lookit that thing whip around…god damn, that’s hot…” His tail was still wagging, and his long orgasm had ended, yet his cock remained completely erect. “Yeah, man, keep cummin’…”
I moaned, jerking myself furiously, still shooting thick ropes and forming some impressive puddles. “H…how am I… STILL cumming?” I groaned.
“‘S the injections,” Rex huffed, breathless. “Makes your orgasms real long. And you can have a lot of ‘em. You’ll see.”
I don’t know how long I kneeled there, jerking off and moaning and lashing my tail and flooding the floor with my cum, but eventually, ropes reduced to dribbles and I finished with a couple firm, slow strokes. My ears were ringing, heart beating fast, chest heaving for breath. My tail slowed, but still swayed like a serpent. And indeed, my cock was still rock hard.
I looked up at Rex. “Wow.”
He laughed. “Right? Now, come on…” In a sitting position, he slowly spun around so that his back was facing me. His thick tail stuck out proudly, grazing the floor as it casually wagged. “Come stroke this.”
I gulped, and my cock pulsed. I crawled forward, taking in the appearance of his dog tail. It was gorgeous. I didn’t need any convincing. I reached out and groped the appendage greedily, huffing. Rex moaned ecstatically, and his tail wagged harder. Sloppily I stroked it, massaged its powerful base, touched and squeezed it in every way I could. Rex bent low and shoved his ass out as he whined in pleasure, clearly loving the sensations.
“Ahh yeah, keep touchin’ it… just do anything you want, feels so fuckin’ good! Makin’ me wag again!”
I moaned at his words, deeply aroused by the feeling of his tail and the way it kept escaping my grasp with its powerful motions. “Ah fuck, it really turns me on when it wags so hard,” I confessed, feeling my own tail lash behind me. “Think it’s makin’ me wag too! And it feels awesome!” For awhile, the room was silent save for our mutual breaths and moans as I massaged, unable to keep my hands off the rigid labrador tail. My cock was at full mast and visibly throbbing, as if I hadn’t just pumped a veritable lake of cum all over the floor!
I adjusted my posture in such a way that the furry tip of Rex’s wagging tail grazed the head of my dick. I shuddered, leaking a bead of pre. I gulped, heart racing, overcome with desire…and forcefully I grabbed his tail, scooted closer, and bucked my hips so that my cock slid right up against it. My cock jerked and I let loose a boisterous moan, and I just about lost control. I was frotting with Rex’s tail, rubbing myself all over it, spurting little ropes of pre into the shiny black fur, feeling it up and grinding into it with total abandon.
Rex was letting loose raucous moans of his own as he shoved his tail further into my grip. “God damn,” he breathed, a little chuckle passing his lips. “Hot as hell. Fuckin’ my tail like that. Mmm…think I need a turn with yours!”
Before I knew it, Rex had spun around and torn his tail away from my eager cock, and was crawling over towards my hind end. I saw his erection, sticking out like a flagpole and leaking a line of pre. He crept around me on all fours, his dog tail held aloft and sweeping from side to side sensually. Then, I shuddered as I felt his strong hands grasp my tail. He worked it expertly, stroking and massaging its length, and then he recalled its most sensitive spot. His fingertips dug into the thick switch at the end and caressed my blunt tailtip. “Oh-OHHHH!!!” My cock jumped and shot pre as he went to work. I glanced in the mirror, seeing my long dark tail in his hands, watching his own powerful tail jauntily wag. The sensations were unbelievable; almost too much, and I could only moan in response and shove my ass out closer to him. My cock was screaming with need, and I had to stroke it. I began jerking furiously, my pleasured huffs and groans mingling with the wet smacks of my hand pulling at my engorged member.
I heard Rex chuckle in my ear as he pulled on my tail and massaged its root. “Need to cum again, huh? Why don’t you get a little personal with this tail of yours?”
He let my bull tail loose, and it whipped wildly behind me, smacking the floor. He grabbed it by the tip and brought it around to the front of my body, positioning himself in front of me. “Quit jerking for a second.”
I forced myself to pull my hand away, breathing heavily. My stiff cock protested, twitching and drooling. I watched intently as Rex brought my tail closer and closer to my dick. It was swishing crazily in his grasp, and soon the switch was smacking into my cock. “Oh FUCK!!!” My cock squirted pre as the long wiry hairs of my tail’s switch delicately grazed it. Rex held it there, and I kept uncontrollably thwapping the end of my tail against my own erection. I couldn’t believe how good it felt…the two sensitive appendages meeting, each offering the other a world of sensory pleasure.
“Oh god, Rex, it feels so good…” I couldn’t look away; the image of my tail and cock colliding was so sexy! Rex grinned and brought more of my tail’s length into my lap. Gently, he pressed my tail up against the underside of my dick, holding it there. “Okay,” Rex instructed, “Jerk like that.”
He guided my hand to my cock, placing it so that I grasped my member while holding my tail in place. I shuddered at the feeling; at the sight of the end of my tail whipping around just past the head of my cock. I began to stroke…slowly, and then faster, and faster. The feeling was superb…I had to imagine this was what jerking off with two cocks would feel like. I was huffing and moaning, frotting wildly with my tail, thrusting my hips, my balls swinging. Rex was sitting there and admiring his handiwork, going to town on his own massive erection.
“R…Rex?” I gasped, not pausing my masturbation for a second. “If I could just…watch your tail wag…”
His eyes lit up. Not another word needed. He spun around and stuck his ass out, and that thick, sexy tail was flying back and forth at hypersonic speed. I moaned at the sight, shooting pre.
“Ahhh fuck, Rex! Yeah, keep waggin’ it! Wag HARDER! Fuck, I’m so hard! Feels so fucking good! My tail! Jerking my fuckin’ tail!! I have a TAIL! Fuck, man, we sprouted sexy fuckin’ tails right through our briefs! I grew a goddamn TAIL…”
Now Rex was beating off furiously, too, his tail picking up the pace as he pushed his ass out closer to me. “Damn right,” he groaned, “Feels so fucking good…I can’t stop…ohhh FUCK! I love to fuckin’ WAG!” He paused for breath, and I heard the rapidfire, slick sounds of his hand rocketing up and down his rigid shaft. I sped up my own hand, feeling my next orgasm rapidly approaching. I panted as I stared at his tail, its every thrash bringing me closer, turning me on more.
“Rrrrex… ohh god, oh fuck…Rex, I’m close,” I whined, not peeling my gaze away from that dog tail for even a moment.
He let loose a moan, his arm flying up and down as he began stroking himself faster. “C’mon man, shoot! Cum all over my fuckin’ tail! Fuck!”
“AhhhHHHHH! OHHHHHH!!! UUUHHHHNNNggghh GOD!” Pleasure crashed down over me as I humped the air and my cock exploded, thick ropes of white cum shooting forth and splattering across the floor, across Rex’s wagging tail, across the tuft of my own tail that I still was squeezing against my spasming rod. I groaned deeply as shot after shot sprayed from my tip.
I let my tail go and it swatted wildly. Cock still shooting, I crawled closer to that wagging labrador tail and aimed my member at it, unleashing rivers of cum like a gardenhose. I grabbed his tail forcefully, kneading greedily with one hand while my other hand aimed my endless ejections into the shiny black fur. I was completely drenching Rex’s tail with my cum, hot white pools forming in the hairs, dripping to the floor.
Feeling the force of my ejaculation against his sensitive tail was enough to send Rex over the edge. “I’M ‘ONNA SHOOT!! AW FUCK!”
Fapping furiously, he unleashed a howl of ecstasy as his own cock began spurting like a fountain, sending ropes clear across the room, their splatters clapping loudly against the smooth walls and floor. I moaned and bit my lip as I squeezed my cock, grinding my tip deep into his fur and creaming the fleshy tail beneath. I had utterly soaked the top half of his tail, and lifting it up, I began to hump into the sensitive underside of his tail root, still shooting my endless load.
“Aw GOD,” he groaned, spouting cum onto the floor. “FUCK yes! Ohhh my god…empty your fuckin’ balls…ALL over my tail! Mmmff…DRENCH that thing! Fuck!”
He didn’t need to ask. My heart beat out of my chest, my face reddened, and I let loose a scandalizing moan as I caressed the thick dog tail and milked my cock for all it was worth, squirting all over Rex’s hairy new appendage. He was still jerking off, too, and I could hear the spatters of cum collecting on the shiny flooring. My stroking slowed and became more forceful as I felt the seemingly endless wave of orgasmic pleasure gently ebb away, depositing a few final white beads of ejaculate into Rex’s fur. Exhausted, I sat back, taking big heaving breaths as my stiff member jerked and expelled its last little dribbles. Weighed down by my cum, Rex’s tail was swaying slowly and heavily, absolutely drenched and dripping in my seed, its dark coloration nearly masked by a layer of translucent white. I took in the scene with amazement, absentmindedly kneading the tip of my long tail.
With a few animalistic moans, Rex’s jerking slowed. His cock had been shooting ropes several feet into the air, but slowly his ejections were becoming more modest, until he too reached the end of his incredible climax, coaxing out the final drops with a tremendous sigh. He sat there for awhile, chest heaving, his tail drooping to the floor. It brushed across the ground and left a slimy trail of cum in its wake.
With great effort, he turned to me, his facial expression both tired and exhilirated. We locked eyes, mouths agape as we caught our breaths, and wordlessly exchanged feelings of wonder. Then we both looked around, smelling the thick scent of cum, taking in the shocking sight of the floor and walls totally drenched in our ejaculate. Both our cocks were throbbing and stiff, stretching towards the sky, seemingly ready and eager to do it all over again.
A long pause, and then Rex smacked his lips, mouth bone-dry from all his moaning.
“So…the tails will last a few hours or so. Then maybe we can go again. Sprout some new ones. I think I’ll grow a rat one. You?”||
