A Mad Doctor gets a surprisingly willing victim in Hooves the Zebracorn, but the myth gets more than he bargained for in the wicked Bull


Specimens

The trouble with living a really long time, is that sooner or later even things you really like begin to bore you. And if you're a quasi-immortal myth, who can regenerate almost any damage and your something of a masochist. Always looking for new experiences, well you can find yourself in all kinds of strange places. Meeting all kinds of new and strange furs, and so it was the Zebracorn found himself strolling into the lonely ruins of a power plant. Forgotten and abandon, it sat hulking on a bit of land jutting out into the great lake rusting and decaying slowly. It was not the kind of place the sylvan creature would normally ever go, it point of fact it seem to be a place no one would ever go. Unless they wished to do things... forbidden things and not be disturbed, this was just the kind of place for that.

The sleek striped Zebracorn followed the green stripe painted on the floor, just as he had been told to do. Through the courtyard and into the power plant building, there were lights here to push back the darkness. They were weak flicking lights that seemed ready to burn out at any moment, and added a creepy thrill to the atmosphere that excited the myth. Deeper and deeper he moved into the huge building, until at last he stepped out into a huge room. The lights were brighter and steadier here, looking around Hooves saw that the room had been converted into a makeshift laboratory. The huge shiny black bull stood in the center of the room, he was dressed in a white lab coat over baggy green scrubs. Looking for all the world just like any Doctor, you might meet in any hospital in all the world. "Ahaha you came..." The hefty Bull snorted with a smirk, it was plain he wasn't really surprised... he had done his homework on this creature. "I'm so very glad to see you... you can truly help millions of suffering you know. And your all ready undressed... you must be very excited to get start... come over here please."

"I'm not really sure how I can help..." The big Zebracorn grunted, as he strolled over closer to the big bovine noticing that the Doctor was already wearing a couple of pairs of rubber gloves on his huge three fingered hands. "But I will admit I'm somewhat excited..." The big equine answered with a grin, as the big Bull looked down at the myth's long black erection.

"Heh... I can see that you are... atmospheric stimuli often cause such reactions, I've noted in the past." The heavy older Bull admitted, as he examined the smiling myths sleek naked body. "Please lay on the table and we'll get started..." The Doctor watched as the handsome Zebra Unicorn hybrid lay down on his bare stainless steel morgue table. As he got into position, the Bull started pulling out straps, instructing the Zebracorn to lay in a particular place or way, strapping him down onto the table slowly and always making sure he was comfortable. The big Bull quickly placing restraints onto the myth's arms, legs, and long equine neck, chuckling at the myth's apparent fearlessness. The magical creature could escape from normal bonds at any time, if he didn't enjoy it the Zebracorn would just vanish. Turning around the big bull threw a massive old switch a few seconds later, the myth felt a strange, fuzzy sensation as the machine clicked on. Like someone was pressing against him from all directions, over every square inch of his furry body.

"There." The suddenly evil looking Bull chortled, licking his lip's like he was looking at a fine meal on his dinner table. "That should keep you from teleporting away or anything like that." He was almost giggling in glee, knowing that was one of the biggest defenses the Zebracorn depended on. "We wouldn't want to interrupt the results, after all."

"Wait what?" Hooves grunted, as the powerful energy field buffered his senses with that odd sensation making his fur stand on end. "Ammm ok no teleporting I guess." The Zebracorn breathed, feeling a thrill of fear and excitement race through him at that knowledge. He was trapped his heart was beating faster, that long black stud stick jerking and pulsing as the massive bull loomed over him. The big bovine reached up and pulled a microphone down, until it was just above his massive horned head.

"Subject number 1243, species Zebracorn... male adult, sterile but otherwise healthy. Objective; Discover the reason for subjects remarkable healing and regeneration abilities, and reproduce it in a second subject. Secondary objective: Test the absolute limits of said healing and regeneration abilities, along with furthering my research into pain management and subjective subjugation in test subjects." The big Bull grinned, as he examined the Zebracorns sleek smooth striped body. Those thick latex clad bovine fingers explored Hooves eager male organs, fondling that throbbing cock before moving lower to examine those fat orbs.

"Ammmm testicles show little to no sign of atrophy... and yet it is obvious from your bodies soft slightly feminine rounding that they are producing almost no male hormones at this point." The hefty Bull paused to stroke his chin thoughtfully, as the helpless myth lay there looking excited and pent up. "I analyzed the blood and ejaculate samples my agent took when he contacted you." The Doctor licked his thick bovine lip's, smiling faintly as the Zebracorn looked vaguely uncomfortable. "You are utterly sterile... and the production of male hormones in your body is at preteen levels. Yet your testicles appear healthy and full... your penis is certainly working... even eager one might say. You have lost your male organs hundreds if not thousands of times... and regrown them full and healthy every time. Why suddenly have they grown back nonfunctional? Let's see if we can find that out... Shall we?" The wicked Doctor pulled a tray of instruments over, picking up a glittering stainless steel scalpel up in one hand. While cradling those velvety black equine plums in his other gloved hand, those thick rolling back into a slightly deranged grin.

"Ammm how... how are you going to do that?" The striped myth asked, as a faint tremor raced down his strong spine making those hefty orbs tug at the bulls grip. The hefty black Bull smiled, if it was meant to be a reassuring smile it failed horribly. It spread far too wide, making the bovine appear part reptilian or simply mad.

"Why by dissecting them of course..." The Doctor said it, like the idea of cutting someone's jewels up was just a common sense measure. He drove the razor sharp blade of the scalpel through the soft, loose skin of Hooves pouch drawing a sharp intake of breath from the myth.

"Ahuhuuu... That hurts." Hooves moaned out, as the skilled bovine opened his sack up so that both organ's dangled naked. Zebracorn blood sparkled a deep crimson, thick and oily as it clung to the blade and the bulls gloves. The sleeks myths body trembling and tugging at the restraints, but can do nothing to resist and is forced to just endure the pain.

"Yes I'll wager that it does..." The Doctor smirking, as he held Hooves fat right ball in one gloved fist slowly looking it over before speaking into the microphone over head. "Subjects right testicle appears whole and undamaged, blood flow unrestricted, no deformations, growths or tumors. There is a odd softness to them, as if they're under inflated toy balls in a way. Let's have a peek inside..." And with that, he slid the edge of the scalpel along the base of that fat nut, with the tough outer skin pierced. The pink inner flesh seeming to jump out slightly, funny looking little pink coils of meat. Hooves had never seen the inside of his own nuts before, at least not up close like this anyway. They were normally being mangled between some predators fangs when he saw them, this was both more shocking and oddly fascinating.

"I'll need to collect samples of seminiferous tubules, they make up the bulk of the testis and are lined with a layer of epithelial cells from which the spermatozoa are produced." The Bull explained, as if he were merely lecturing some student about the organ's being dissected. The sleek striped Zebracorn lay there groaning in pain, his fur covered in a frothy sweat like he was running flat out. "Fascinating isn't it?" The big Bull turned his head to look down at the helpless equine, a odd kind of gloating smirk of that nasty bovine muzzle. His smile it anything wider and even more demented than before, as he leaned closer to examine the flesh he'd just cut into. "I can always tell when someone is interested in the work... I'm glad to have so willing a partner in this endeavor." One big gloved hand teasingly stroked the myth's long black stud stick, which was jutting up rock hard and leaking pre-cum onto Hooves chest. The big Bull clearly understood how to use pleasure to mute the pain, or at least distract from it with the promise of orgasm.

"It's nice to have someone to converse with while I work... my other vict... volunteers are either unconscious or in shock by this time. This regeneration power of yours keeps you delightfully aware, I really wished I'd worked with someone like you sooner. But then you are something of a rarity... processing the traits you do and willing to stroll so eagerly into my trap... procession... Errr... so eagerly coming to my assistance." The big Bull corrected himself as he sliced out samples of tissue, placing the flesh between glass slides. "The epithelium of the tubule consists of a type of sustentacular cells known as Sertoli cells, which are tall, columnar type cells that line the tubule." Hooves strong body had began to shake, as the myth pulled on his restraints futilely. The myth's magically healing powers seemingly keeping him on the edge of shock, allowing the Bull to enjoy explaining things. "In between the Sertoli cells are sermatogenic cells, which differentiate through meiosis to sperm calls. Sertoli cells function to nourish the developing sperm cells, they secrete androgen-binding protein, a binding protein which increases the concentration of testosterone inside the seminiferous tubules."

"Ohooo gods I can feel it up in my guts..." Hooves moaned out passionately, as he couldn't stop watching as the Bull filleted his left testicle as well. Taking numerous tissue samples, labeling each one before setting them aside for the moment.

"Ahaha yes, well it all comes down to biology you see." The smirking Bull explained in delight, as he removed the remains of Hooves right testicle completely. While leaving the left one filleted, but still attached to the Zebracorn's body wanting to see how thing would right themselves. "Your testicles actually developed in your abdomen... near your kidneys. From there, they descended toward the scrotum, pulling the sensory nerves along with them as they go." The mad Doctor chuckled, as he began to look at the samples he'd just collected under his microscope. "That means you have sensitive nerves, that stretch from your stomach all the way down into your scrotum." The big bovine 'Tsktsktsked' softly under his breath, as he look at slide after slide slowly. "So when the goodies are bashed or squeezed, the nerve endings send a signal to the upper part of the belly, which is why it hurts in the stomach when you're damaged down there." The hefty Doctor began to chortle, softly at first but it soon grew into a kind of maniacal belly laugh. "Your Sertoli cells have withered and are producing no new sperm cells, in fact they appeal to have converted into fatty cells. This should enhance the flavor of the meat, it appears that your body has adapted it's self to your hobby of being prey. That hints at some mental control, most likely subconscious on your part. I have been told that you are a submissive pleaser... your body is actually making its self more tasty for the predators you court. Or perhaps it's because a ruptured testicle exposed your immune system to your sperm. As a result, your immune system may consider your sperm as something foreign so it attacked your testicles to try to keep you safe." The hefty Bull chuckled as he strolled back over towards the helpless myth, pausing to stroke Hooves forehead with one bloody gloved hand.

"It also appears that your brain is secreting very little gonadotropin releasing hormone, which explained your low testosterone levels. We know this because of the lack of follicule stimulating hormone and luteinzing hormone in your tissues. When the FSH and LH reach the testicles, they tell them to do two different things. FSH kicks off sperm production, while LH stimulates the Leydig cells in your testicles to create more testosterone. And plainly your Leydig cells have atrophied to less than half what is normal, which no doubt explains your softer more feminine appearance. But that leaves us with the mystery, of why your brain has stopped secreting gonadotropin releasing hormone." A look of shocking glee spread across the mad bovines muzzle, making the helpless Zebracorn shudder in fear and dread. Hooves was use to hungry predators and cruel tops, but those took their pleasure and quickly left. This Bull on the other hand would not be easily nor swiftly satisfied, and unlike those pred and tops he felt that this mad bull had no limits. "This is going to be so much fun... there are so many experiments we can do together." The mad Doctor examined the severed cord, discovering that a new testicle had already formed on the vine. While the filleted orb had reassembled it's self and sealed back up almost completely. "Excellent... let us see how damage from a thermal burn does." He chuckled merrily, as that fat healing orb was sliced open once more. Making the helpless Zebracorn moan in pain again, smirking the big Bull reached over and picked up a propane torch. It 'clicked' and then a short blue flame became visible at the end of the nozzle, Hooves eyes opened wide in shock and horror.

"No... No wait..." The myth squealed, as he watched the big Bull shove that nozzle down into his split open nut. "No nononoOHOHOO!" Hooves screamed as the air filled with the scent of roasting nut meat, and the sounds of popping and cracking as the fatty tissue melted and cooking. The myth watch as the insides of his testicle blacken and burn, tears of pain from the agony soon blurry his vision.

"Perhaps a bit too well done..." The fat black Bull joked glibly as he sat the torch aside, while the sweaty Zebracorn bucked and withered in agony. "My... my... your new testicle is almost fully grown..." The Doctor observed as he split it open and took some samples, before pulling it back together watching the two half's heal together. "It really is an amazing power... I hope we can preserve it... if not in you than perhaps another test subject." Turning he left the agonizing myth on the table, to examine the new tissue samples while those damaged organs healed up. "Same trouble as your former organs... it seems something in your head is keeping you from returning to the studly Stallion you once were..." Strolling back over he looked at that new organ, it had sealed together but its growth had slowed down considerably. 'So the healing process was retarding the regeneration process... interesting because it hinted at limits to the Zebracorns so call magical powers.' "We will be having a look inside of your head... before we are done of course. Perhaps you have a brain tumor... or some other defect... of course it could all be an entirely psychological situation." The fat bovine smirked as he watched the scab flaked off, and the new testicle was whole once more. Taking down a large glass vessel he lay the newly forming orb inside, and then took out a dark brown glass bottle. "Either way we I do have ideas for combating it... not that restoring your abilities to sire offspring is a objective. In point of fact it would be much more entertaining to make you utterly impotent, unable to even get this big useless organ of yours erect. Predators would still enjoy eating it... even if you can't get hard after all. Heheh."

"Let's try chemical burn next... a bit of acid should make things interesting." Unstoppering the bottle, the heavy bull poured the clear fluid over that exposed flesh making the tied up Zebracorn squeal and buck within his restraints. The clear acid began to yellow almost at once, as did the meat of that growing gonad. It actually felt more like fire on that quivering flesh, than the open flame from the torch had. The mad Doctor moved over to observe the torch charred left nut, poking at it with his scalpel as he noted that burned flesh took longer to regenerate.

"EEHEHEEHEE..." The myth was screaming and squealing, as both of them watched that clear acid darkened to a smoky brown. Gummy strands of flesh looking like melted cheese began to peel off, floating up to the surface as that acid darkened more and more. Slowly the caustic fluid burned away that tender male flesh, oddly even as his testicles were repeatedly destroyed the Zebracorn's long black stud stick bounced and flexed excitedly. Clear sparkling pre oozing and dripping from the myth's prostate gland, the fat Bull's latex clad fingers rubbing that slick slime all over the big blunt tip of that cock. The air already thick with pain and fear sweat, soon grew rank with the smell of acidic fumes as that nut meat was slowly destroyed. The Zebracorn's body fighting to regenerate that flesh, even as the acid burned and destroyed it.

"So it seems your powers of regeneration aren't limitless... things are slowing down, as your body struggles to repair the damage being done." Taking down a second glass vessel, the Doctor placed that torch burned orb into it. The charred flesh was just beginning to fall away, as healthy pink nut meat began to regrow in its place. "Let's see just how much you can manage..." The huge black Bull snickered, pouring the rest of the acid over that second wounded orb. Making the weakly struggling myth bounce and scream once again, as fresh pain blossomed within his groin as the acid went to work on his other jewel. The Doctor then examined the edges of the myth's ruined sack, which had been regrowing at a rapid rate. But was now only very... very slowly pulling its self back together around those exposed tubes and cords. "Hmmm... fascinating really the regrowth process takes a great deal of energy... I wonder how much greater damage will slow things. Shall we see?"

"No... no please, no more." The sleek handsome black and white striped myth denied, shaking his long narrow equine head negatively. His tear filled eyes looking up at the older bovine pleadingly, while the doctor moved down the table to the Zebracorn's knees. Pulling the tray of none to clean instruments over within easy reach, pulling the heavy leather restraints even tighter on the myth's thigh's.

"I've been wanting to see if a large part of your body would grow into a new Zebracorn if cut off..." The big Bull admitted with a maniacal grin, was the helpless handsome equine begged and pleaded. "And then... if that doesn't happen we can move on to cutting you in half, to see if you're like certain worms... that if you will grow into two Zebracorns." The helpless equine was trembling as he listened to the big Bull giggle insanely, and then he was wincing as that sharp blade was driven into the flesh of his right knee. Big strong hands sawing that blade through tough flesh, as the myth screamed and whinnied in agony. Bright rubies of crimson blood staining that white and black striped fur, dripping down on to the shiny stainless steel table top. It took quite a bit of effort to cut through that point, the Zebracorn's testicles had completely dissolved in the acid. By the time that lower leg came free, smiling the big Bull set it aside on a nearby table. The dangling tips of the myth's cords and tubes... slowly growing down until they touched the liquid, only to smoke and sizzle. Hooves body stubbornly trying to regrow that lost flesh, even as the acid ate away any new flesh. "You know I detest the asymmetrical..." The fat Bull snorted with a frown, as he looked down at the Zebracorn's slowly bleeding leg stump.

"Wha... wha..." Hooves head was dangling weakly to one side... the handsome equine clearly only semi conscious. His handsome stripped muzzle wet with tears and pain sweat, drool spilling out over his thick equine lip's as the bull reached up and smacked his cheek gently. Clearly the levels of pain had over loaded his mind, and his body was pumping out endorphins to deal with it.

"I'm going to cut off your other leg..." The Bull explained with a oddly aroused sounding voice, as his gloved fingers gently toyed with that furry knee. And with that he jabbed that razor sharp blade into the back of Hooves left knee, and began cutting through muscle and tendons. As a hoarse squeal of pain escaped the myths throat, as he watched bleary eyed as what scared a equine more than anything happened. His leg's being removed at the knee, the pain muted by the rush of natural pain deadener.

"Let's try an experiment - or maybe more like a challenge? Let's see which is faster - your regeneration, or my acid? It'll be like a race." The hirsute Doctor reached under the table to pull out a medium sized plastic bin, lifting the small glass acid containers away from the loose nut cords. "Don't worry, it's polytetrafluoroethylene, the acid won't melt through it and ruin my floor. I know that's your main concern." The big Bull sarcastically chuckled to himself as he sat those beakers aside, and then began pouring the rest of the acid on hand into the bin, opening up a second volume once the first had run out. When the bin was finally a full two feet deep, the Doctor reached underneath the cold slab to unlock the tilt mechanism, standing the struggling Zebracorn upwards. The bovine grasped the myth's waist to slide the acid bin into place, Hooves' mangled leg stumps submerged in the quick dissolving formula. "If you're able to touch the bottom of the bin with your Hooves, you win. If you can't, you're still my favorite loser... either way, we'll get some valuable data on the rate of your abilities."

"EEEHEHEE!" Hooves screamed out loudly once more, as the bloody stumps of his legs began to burn within the acid. It was obvious from the acid on his nuts, that the myth's body wasn't able to outpace the destructive power of that caustic liquid. The big Bull stepped back watching for a moment, as those stumps wiggled and jerking. Splashing dribbles of that slowly yellowing fluids up onto his sleek black and white striped fur, which began to curl up and darken at once. "Gods... please...You... you know I can't..." The handsome myth protested weakly, his head flopping down limply onto his chest. As the big Bull strolled over to examine those severed leg's, disappointed but unsurprised to see that they didn't appear to be regenerating removed from the Zebracorn's body. He glanced over at those loose dangling cords which had began to develop tiny little bumps, knots of flesh that would grow into testicles. And yet they showed almost no growth, unlike before when that had been regrowing quickly. As the screaming, moaning Zebracorn's stumps blackened and charred in the slowly thickening acid. The hefty bovine moved slowly back over to his patient, reaching over to wrap a gloved hand around Hooves cock. And slowly pushed it down, until the blunt equine cock head was just above the now dark yellow acid. "Nnn Nna... No. No please..." The handsome myth simpered pleadingly, as the sneer Bull slowly submerged that cock flare in the caustic acid. That tip was full of highly sensitive nerve ending, that instantly began to sing with pain as that male flesh began to burn. If the myth had thought he'd felt agony before, having the head of his cock consumed was ten time... twenty times as painful as having his testicles dissolved. Hooves at last slipped into unconsciousness, as the acid burned his big blunt cock flare away slowly.

**

The myth awoke perhaps half an hour later, the tilting operating table was back laying down flat once again. The tub of acid had been removed, even if the air in the room still stank of it and the Zebracorn's burning, melting flesh. "Aha... awake again are we?" The huge Bull asked cheerfully, as he strolled back over to the helpless myth who was still strapped to the cold metal table. "Well our experiments have answered more than a few questions, so that is good. Of course... there are many more experiments we will need to carry out, so many unanswered question remain where you're bodies abilities are concerned." The huge bovine flashed a demented smile down at Hooves, who was looking around in shock.

"Wha... what... why can't..." The big Zebracorn's eyes rolled around in his head, or at least his left eye did. His right eye had been popped out of its socket and was dangling down on his cheek, the difference in vision confusing the sleek equine.

"What... oh you're wondering why things look so odd..." The smirking Bull grunted, moving up beside Hoove's head as he spoke to his helpless subject. "I plucked your right eye out." The Doctor explained, reaching one gloved hand out to cupped the eye ball in his thick fingers. Making the Myth moan in pain as his naked eye ball was fondled for a moment, and then there was a burning pain as the smiling Bull sliced through the nerves and muscles holding the eye in place. "I need to have a look at your brain..." The mad Doctor explained in a eager lust filled voice, that made the helpless Zebracorn shudder in fear. He'd heard that tone in males voices before, normally that lead to some brutal tail hole or throat raping for the myth. And yet Hooves got the feeling, that the Doctor wasn't all that interested in fucking his throat or butt hole. "So I'm going to drill a little hole through the back of your eye socket, just so I can take a little peek inside your head." The tone in the big Bull's voice, left little doubt that he was wanting to do a lot more than just take a peek.

"Oh Gods... Oho Fuck." Hooves moaned as the big Bull lifted the drill, that had a huge core bit in its chuck. The air powered drill made a high pitched scream, as the big Bull pulled the trigger for a second. Sending a thrill of terror and panic racing down the helpless Zebracorn's strong spine, as the grinning bovine waddled forwards.

"Heh... yes... this is going to be so interesting... just the thought of it is making me very excited." The Doctor confessed as he reached out and gripped the Myth's muzzle, pushing the drill bit against Hoove's empty eye socket. And then as the helpless Zebracorn begged and pleaded, the grinning Bull triggered the pneumatic drill.

"WWWEEEHEHEEE!" Hooves squealed out louder, as the sharp teeth chewed into his flesh and bone. The air soon choked with the bitter reek of burning bone, as that bit heated up as it swiftly cut through the bone of his skull. The big Bull chortling softly at first, but as the Zebracorn's screams and struggles grew wilder... it turned into loud guffaws. And then there was a sudden jerk, and the laboring drill raced as it cut through completely. Tugging the bit out, the Doctor pulled the bone core out of the bit examining it for a second. Before sitting it aside along with the drill, the big Bull took a flashlight and peered into the hole at the Myth's wrinkly gray brain.

"Surprisingly normal... except for the fact that your horn base seems to connect into the center of your brain. Isn't that interesting... first we'll get some tissue samples and then we'll have some fun." The hefty bovine snickered darkly, as he lifted a oddly tube like instrument. Shoving it through that gaping eye hole, deep into the helpless Zebracorn's head. The big Bull used it to take a number of samples, both from the horn base and the brain tissue that it connected to. "Now that is done... it is time for a more pleasurable experiment." The big Bull snickered lewdly as he sat them aside, and then shoving his scrubs bottoms down. The huge bovine stepped out of them, his long red bovine cock jutting out lustfully in front of him. "I have to say... your brain is very appealing... one might go so far as to say arousing." The wicked Doctor chuckled as he stroked his long red bovine erection, moving back up beside the table. Guiding the bulbous round cock head into that freshly made hole, as the weak myth nickered feebly as that bulbous head rubbed over the velvety fur of his cheek. Before sliding in a bit deeper into that gaping eye socket, finding the intense body heat and slimy wetness of Hooves brain fluid.

"NNNNAAAHA." The myth's breath catches in his throat, as the Bull places one gloved hand on his muzzle and the other on the far side of that striped head. The rounded tip of the Bull's big cock, slowly pressing into that gaping eye hole. "Please be gentle... as you dirty my mind." The helpless Zebracorn begged weakly up at his evil bovine molester... even as Hooves feels a hot oozing trickle burn inside his ruined eye socket. The mad Doctor's salty pre-cum easing the way for his throbbing fucker, and that long rut muscle rubbed over the hot quivering mass of the Zebracorn's brain.

"Sssh now... we both know there is no way to dirty your mind any farther than it already is..." The hefty older Bull Doctor grunted, slowly beginning to push his long sleek fucker into the helpless myth's eye socket. It's almost impossible to fit that big pulsing cock in there, but the Bull slammed forewords hard driving that stiff dick until it bent almost double. Making the Zebracorn's big three fingered hands grip the sides of the table hard, even as his head was held immobile. The mad Doctor's gloved hand gripped that spiral magical horn and it glows brightly for a moment, as it does that thick organ slides in deeper. The myth's soft hot flesh glove tight around that throbbing member, while the big Bull lets out a snickering moan of pleasure. As he Suddenly feels the soft ripples of flesh rub against the tip of his throbbing fucker and a gush of hot brain fluids seem to coat that stiff organ.

"Wha... Wha..." The helpless Zebracorn stammered out weakly, as the snorting, grunting Bull drew his hip's back. And then slammed forwards again, driving his hard on into that quivering gray matter. That magical lube is just what the Bull needed as his cock penetrates into his helpless victim's brain, a soft squeak accompanying it from the helpless myth. The big Bull felt the Zebracorn's whole body spasm, as his throbbing cock pierces into that soft brain. "Ummm... Ummm... Errr..."

"Ahahaha... Yes." The horny Bull moans weakly, as he humped and thrust against the side of that long, narrow, stripped head... His hard fucker rubbing and stroking into the hot depths of the helpless mythical beasts head, rolling his strong hip's and fucking that quivering brain. Slimy pre-cum spurting over those soft tissues... while the Zebracorn babbled as the cruel bovine balled his brain roughly. The mad Doctor moaned louder as he begins to fuck that quivering brain mass, violating his captive in the dirtiest most depraved way possible. "You have no idea how good this feels..." The lustful Bull moaned, pulling that stripped head against his crouch hard with each deep, slow thrust.

"Gods..." Hooves mouth gaped open wide and the handsome Zebracorn began to drool... as that lusty organ pulses and quivers against his spongy gray matter... "Uhuhuuu..." The myth groans, those bright blue eyes looking far away as the Doctor takes him in a away he's never been taken before.

"Amazing... it's tighter than any pussy or ass, but so much softer..." The horny Bull growled and groaned, holding that handsome stripped head in place... as he began to fuck even faster. The Doctor saw those eyes roll and part of him thinks it is because the helpless Zebracorn is enjoying yourself. Of course the clinically part of him knows, that his hard organ is scrambling Hooves brain. Pounding it into shreds of quivering pudding, for his own deviant pleasure. After all it would be an interesting experiment, would the myth's brain regenerate just as it was before. Or would knowledge and information be lost, it was a question that would be very enjoyable to answer... at least for the mad Doctor.

The Zebracorn was smiling vaguely as stars and bright lights flash in front of his eyes... that slender striped equine body trembling violently. His slowly regenerating black cock jerking up stiffly for a moment and then falling limp only to stiff again a few seconds later. "Hhhuhuuuu fffuuccckk.." Hooves giggles as that huge bovine cock spears deep into his soft spongy gray matter... the grinning Zebracorn unable to protest... as his body quivers in pain and pleasure.

"How's this for a mind fuck." The big wicked Bull snickered as he kept fucking the myth nice and slow, his hard cock going deeper and deeper into the Zebracorn's head. "The rumors about you are now right... you have cock on the brain. Hahaha." The mad Doctor moaned loudly as his hard pounding fucker breaks into that grey matter, causes the myth to see an explosion of lights and pretty colors.

"Ahaha gods please." The suffering myth squealed weakly... as that throbbing cock head pounded against the inside of his head. Even while that stiff shaft drives into his scrambled gray matter, harder and deeper as the Bull's pleasure grows. That big soft belly draping over Hooves striped muzzle, as the horny Bull bred his brain savagely. "Cock my brain... fuck my skull..." The helpless Zebracorn squealed out harder and louder even while the Doctor fucks what's left of his brain, even as those huge bovine balls slapped against the side of that long equine muzzle.

"Heh, it's not like you need one anyway..." The mad Bull Doctor grinned, when he saw the sparkling pre-cum leaking from the Zebracorn's cock as it lay twitching in time with his fuck thrusts. The myth's balls still not having regenerated enough to produce any seed, so that it's only the clear sparkling juices of the prostate gland.

"Ahahh... Ooop." Hooves whimpers weakly as those furry balls smacked against the side of his striped muzzle, splattering Bull sweat and musk all over that handsome head. Moans and giggles as that soft mouth hangs open drooling hard, that long black cock hanging there dripping and jerking wildly. "Wha... wha... who." Begins to shake and shiver in pleasure. as a sparkling sperm less load of magical seed spills out onto examination table.

"They were right, it's more fun when you're brain isn't switched on." The fat Bull laughed, as the most lewd sounds come from those scrambled brains, although he doubts the myth is even aware of them. That wide, flat equine tongue rubs against the Bull's balls eagerly, causing his cock to twitch inside the Zrbracorn head, making Hooves see more pretty colors. "Hope you're enjoying this as much as I am... you brain dead slut." The wicked Doctor taunts, thrusting and driving into Hooves ruined eye socket harder and faster still.

"MMMMMMIMIII..." The sleek striped equine moaned plainly excitedly as each thrust of that hard organ into his brain... causes another wave of pleasure to run through the helpless slut. Triggering a gush of sparkling mythic juices to be wasted on the cold metal table, while that fawning mouth licks wildly at those swinging balls... as the horny bovine gets ready to fertilize the Zebracorn's brain. "Feeel... feellsss sssoooo... Ohoooo look at the pretty colors..." Hooves squeals louder, as that pounding cock goes into over drive churning his gray matter into chunks.

"Hahah..." The mad Doctor fucks that eye socket harder and faster now, spurting pre-cum into the myth's cranium, loving the feel of that marshmallow like gray matter on his pulsing male hood. His huge balls smack hard into Hooves furry cheek, even as that furry sheath smashed into the Zebracorn muzzle... while the Bull gets closer and closer. "Almost there..."

"Weehehee... sooooo many stars." The now plainly brain damaged Zebracorn calls out crazily, as those sweaty balls spread musky sweaty all over the side of his head. The myth's body can't seem to stop trembling and quivering, as surge after surge of pain and pleasure runs through him as the big Bull fucks him.

The mad Doctor's fat body gave a powerful shudder, ragged moans escaping as he filled what's left of the myth's cranium with his hot, sticky and thick Bull cum. Some of it shoots out of the drooling Zebracorn's ruined eye socket, but the rest leaks out of Hooves nose and mouth. "Sooooo...gooood..." The hefty bovine moans, leaning over the helpless myth's head sweating in exhaustion as he smirked down at his moaning victim.

"IIEIEIEEE." Hooves half giggled, half screamed in confusion and pain... as that hot Bull spoo filled the myth's head. Letting those scrambled brains swimming around in a ocean of creamy calf batter. what's left of his mind suddenly filled with the naughtiest, lusty thoughts. Until a curtain of utter blackness drops over his senses, as the damage that had been done at last caught up with him.

Even as the mad Doctor moaned and groaned as the last of his stud milk flowed into the handsome Zebracorn's brain. One latex gloved hand patted his helpless captives stripped head as the fat Bull let his cock go soft inside the myth's head before pulling out. "If you can still hear me, thank you for doing this with me. This was just so hot... we're going to be enjoying each other a lot I think... Heheh."

***

The heavy steel door shrieked as it open on rusty hinges, making the small frightened fur cower in the darkest corner. As the big Bull pushed the wheel chair, with the unconscious Zebracorn slumped in it soundlessly into the holding cell. The mad Doctor shoved Hooves into the center of the room, and then turned strolling back out and locking the door. Slowly the odd creature crept out of the corner, moving over to look the unconscious myth over slowly. Unsurprised to see all the damage to the Zebracorn's body, the Doctor had dozens of other captives before the myth. None of them had survived the Doctors experiments very long, this one seemed to be in pretty bad sharp at the moment. Which was strange because the Bull normally worked slower, trying to keep his captives alive as long as possible.

As the sleek smaller male watched, the Zebracorn's horn begins to glow faintly in the dim light of the locked room. Slowly those leg stumps begin to heal, bones reforming as the myth's amputated limp's start to regenerate. Suddenly Hartley understood why the Bull had went so quickly with this one, plainly the Zebracorn had special abilities. And could heal the damage being done to him, it didn't bode well for the striped myth at all. The Doctor plainly felt that this meant he had no limits, the things he would do to the Zebracorn would be truly horrific.

"Whaaaaa..." The drooling myth moaned out weakly, as his eye lids fluttered and half opened. That single bright blue eye looking glassy and far away, while the other eye socket was a gaping black pit. Hartley shuddered as he peeked into that hole, seeing the metal ring the Bull had fitted into that sawed hole to keep it from healing closed. The Zebracorn's flesh seemed to pull back away from the metal, there was something strange about it a faint glow perhaps. The drooling myth's single eye focused in his cellmate with a dazed look to it, one big three fingered hand reached out weakly. Hooves gently stroked that silky fur, with one clumsy hand as his new cell mate trembled violently the Zebracorn moaning weakly again.

"It's ok... It'll be ok." Hartley whispered weakly, squirming in his tightly buckled straitjacket... while nuzzling at the Zebracorn's sweaty neck. The now mostly conscious myth plucked at the buckles, but they are pulled far too tight for his slowly regrowing stumps to work.

"Yes... I'll get you out of here..." Hooves promised with a soft lisp, his front teeth had been removed making his words sound funny. "I have... Ahem powers... I think..." Hooves rambled trying to remember, but his head hurt so bad and he can't seem to recall much... Just the flash of pain as his body convulsed, and the smiling muzzle of the huge Bull looming over him. He was here to help... a part of him knew that to be a fact, and yet there was something darker and more nasty going on. Yet he couldn't seem to remember and was having a very hard time thinking at all in that moment.

As the smaller fur huff's and nuzzles closer, wanting to comfort his new friend as best he could, licking and kissing his cheek. The big Zebracorn winced slightly at the kiss... his head hurts so much from his long pointed Zebra ears, to his soft equine chin. While his empty eye socket stared at his new friend, slowly weeping blood and slimy Bull cum down that striped cheek. Milky pink tears crawled slowly over that black and white striped fur, the myth seemed unaware that they were there.

"I know he hurt you... soooooo much." Hartley whimpered, nuzzling under the Zebracorn's chin, to reassure him that everything would be alright. The Myth wrapped a arm around that slight body and pulled it in close to his side. Seemingly unaware that his new friend was trying to comfort him, the myth's lisping slurred voice uttering comforting comments of his own.

"Yes..." He admitted very softly, that big striped body quivering and trembling harder for a moment at the memories of the pain. "No doubt about it things are going to be fine really... just look at the dappled sunlight streaming through the tree's. Doesn't it feel good on your fur... things are looking up already." The brain shattered Myth gestured to the dark barren room they were locked in, with its single naked light bulb flickering weakly over head. The smaller fur moaned in despair at his companions delusion, hugging and snuggling while sniffling softly as tears ran down his cheeks.

"Yes..." He repeated as soothingly as he was able, struggling hard to match the Zebracorn's wide if vague smile. As his new friend's head slumped and the mighty myth was unconscious once again, they were still cuddled together a few hours later. When the cell door opened, instantly Hartley retreated to his dark corner in fear. As the fat grinning bovine strolled over, gripping the wheel chair handles he wheeled the slowly recovering Zebracorn towards the door. "Errr... Wha..." Hooves grunted, his head snapping up as they left the near dark room behind wheeling back into the Doctors laboratory.

"Ahah awake again are you... ready to help me with some more experiments?" The grinning Bull asked in a bright cheerful tone, as the helpless myth looked up at him in confusion.

"Wha... what are we... Who are you... I can't seem to remember what we were doing last..." The still brain injured Zebracorn stammers weakly, as the big bovine Doctor lifts him onto the table and beings strapping him down.

"Not to worry... that is why we keep notes after all." Reaching up the Bull's huge gloved hand pulls the microphone down and begins to speak into it. "Second session with subject number 1243..."
