Close to the witching hour the light of a bright full moon enveloped the many towers and turrets of Hogwarts in silver rays. None but the occasional flickering of candles or torches in some of the windowpanes revealed that there still were inhabitants who not yet had found peace in their sleep. One of these restless souls was Katrina. The head girl's badge pinned to her chest entitled her even at that time of night to roam the many corridors of the castle, when the call of her bed once again couldn't reach her.
Oh, she loved these walls so much! The eighteen-year-old Hufflepuff felt sorry, that she had to leave the school soon. All the things she had experience during the past seven years came to her mind! Her first crush, her first kiss, her first sex, her first heartbreak! She usually knew how to enjoy life. A good two years ago the captain of her Quidditch team had popped her cherry and since then more of those explicit encounters with the opposite sex had followed. Sometimes the young woman asked herself what her Muggle parents or the professors would say if they knew about the other games apart from chess and gobstone their protégées frequently played. Despite all well-intentioned rules and precautions, generations of young witches and wizards had consistently invented ways to secretly take part in these illicit activities. No one could stop it! Especially since the countless couples were very rarely caught. Therefore, the immoral swamp into which every adolescent teenager inevitably plunged at some point in mixed-sex cohabitation, usually remained hidden deep beneath the staid front of that prestigious educational institution.
Katrina turned a corner and followed the moonlit corridor on the first floor. When she passed the hidden passageway between McGonagalls office and the Transfiguration classroom, the thought struck her, that her boyfriend – now ex-boyfriend – had banged her behind that very tapestry precisely three weeks ago. A soft gasp escaped her in the emerging memories of that delicate adventure. Kevin might've been a jerk, but after all they had lots of fun together! In that very moment she missed him deeply and started to caress herself. Soon her fingers brought back that wonderful tingling sensation in her womb his presence always had caused. Suddenly she stopped and pulled herself together. To be caught masturbating – unthinkable! And Professor Snape of all people usually tended to show up exactly when you didn't need him at all. Only Filch would have been worse. Katrina shuddered in disgust at the mere thought of the wheezy caretaker.
To finish what she had started, the young woman needed someplace else; someplace undisturbed; someplace hidden! She considered carefully! The Astronomy tower came to mind! No! The uncomfortable and freezing conditions up there weren't very appealing. It took lots of magic to properly prepare the place during winter. Maybe the prefects' bathroom, then? Also, no! After all those times she already had used it – too boring. Besides she never liked that stupid mermaid staring at her, when she did it to herself. Suddenly she had an idea! If rumours were true, a secret tunnel existed somewhere near the Whomping Willow. Katrina looked out of the window and at the very tree standing motionless in the moonlight. She sighed and shook her head. Probably all just fairy tales! But on the other hand, a little night stroll couldn't hurt and maybe there WAS a dash of truth after all!
Suddenly it was no longer her hunger for salvation, but her thirst for adventure that made her set off. She had to satisfy her curiosity – NOW! It didn't matter that it was at dead of night! She wanted to know once and for all! Fast and unseen she descended the marble staircase, crossed the entrance hall and slipped through the large oak front doors. The cold and clear night air welcomed her. She involuntarily closed her eyes; took a deep breath. During those silent hours the world was a different one – still and almost magical. Katrina smiled as she crossed the large lawn. Her eyes wandered over the Black Lake and then up into the star-studded sky. The feeling of deep satisfaction flooded her, and she almost forgot why she was approaching the edge of the forest; almost sat down on a stone to enjoy the peace and quiet of that marvellous night. Almost! A little voice deep inside her head nagged and urged impatiently. She had to go on!
As soon as the young woman reached the Whomping Willow, the tree lived up to its name. By no means placid and tranquil anymore, the magical plant lashed around as if out of its mind. Thin branches hissed through the air and missed Katrina by only a few inches. The horrible creaking sounds from the gnarled trunk drove her several steps back. No wonder, no one ever had been particularly eager to find out the truth about the tree! That aggressive monster simply seemed insurmountable! But then the Seeker's eye by chance spotted something that made her heart skip a beat—a small, inconspicuous bump on the trunk. Hadn't every single one of these vague stories talked about a knot?
Katrina feverishly searched for a stone, aimed and hit. For a split second, her opponent froze! That brief interruption of the tree's continuous attack told the young woman everything she needed to know. If only she could touch this small bump a bit longer, then she would have had enough time to take a good look around! Again, she started to hunt for any efficient object, preferrable some sort of long and thick branch. At first it seemed the thing she needed was nowhere to be found, but then she finally struck gold. Half hidden in a leafless bush the perfect stick gazed at her!
With a firm grip around her new tool, the young woman started to poke at the small mark. Her heart pounded viciously! Like the thousand serpents of a Medusa, the whomping branches were everywhere; whipped through the air whistling; threatened to smash her only hope to pieces with a single blow. The tree very well knew how to defend the chink in its armour! Only patience and a lot of skill finally helped to outwit that relentless defence. Relieved Katrina continuously pressed the small knot, while she stepped cautiously between her opponent's frozen weapons; searched intently. Nothing! If her foot hadn't slipped a bit, she probably would have overlook the narrow and well-hidden opening covered between thick roots. She couldn't believe it! So all the rumours INDEED were true!
The success of that nocturnal adventure had by no means gone unnoticed. Severus Snape, the master of potions by profession, observed warily the strange behaviour of the Whomping Willow. He stood motionless at the very window through which Katrina herself less than half an hour earlier had looked. A silent anger welled up in him. Whoever was poking around at the edge of the forest would deeply regret it! With billowing robes Snape hurriedly left the first floor, but his chase was abruptly interrupted by Peeves. Of all places it happened to be the marble staircase the troublemaker had chosen to practice his juggling. Metal helmets flew through the air and clattered earsplitting down the stairs. Snape would have loved to leave this little fish for Filch to make a real catch tonight, but mischief done right under his nose he simply couldn't ignore. So, for now, he had to postpone the pursuit of his actual prey and first took care of the ruddy poltergeist.
Meanwhile Katrina followed crouching a long and low passageway hewn into the hard soil. All-encompassing darkness swallowed the faint light of her wand tip; making the path in front of and behind her seem endless in equal measure. The further she went, the more uneasy she suddenly became. It seemed as if by now she already was miles away from the safety of the castle. Should she really continue? Her steps slowed down, when the path gently increased and then disappeared in a bend. The crackling of a fireplace distinctly could be heard and dancing shadows on the walls greedily stretched out there many arms to engulf the cautiously approaching woman.
Katrina irresolutely stared at the breach in the wall; tried to make out the room behind. Turn back or move on? She silently fought with herself. The fire scared her out of her wit's, but on the other hand had she come too far to run away now! The room was empty! Whoever had lit the fireplace didn't seem to be around anymore! The young woman felt a bit more sure-footed. Just one peek, then she'll be gone!
The few pieces of furniture seemed old and had been patched up in many places. Not magically, as she realized on closer inspection, but the way Muggle did it. Astonished, she let her hand rest on the back of a large wing chair. Who on earth would live here? Curious she crossed the firelit room, but she still couldn't find any clue of its inhabitant. Finally, the stairs to the upper floor attracted her attention. For a while she listened intently for a sound; anything that would have betrayed the presence of another soul; a soft scratching; a cough; the shuffling of feet. But apart from the constant crackling of burning wood, she heard nothing but complete silence above and around her. Katrina was suddenly absolutely positive that she was alone! So why not take a look upstairs?
With a reckless nosiness she climbed the steps, only to find an ajar door on the upper landing. Gently she pushed it open. The first thing she could see through the growing gap was an enormous four-poster seeming to wait just for her. Bull's eye! Grinning like a Cheshire cat Katrina crossed the threshold! Here too a blazing fire was lit but distracted by the inviting sight of the comfortable bed the young woman simply omitted that fact just as she failed to notice the two other occupants in the room! A huge black dog and a grey-brown wolf followed every single step of their unexpected guest, ears attentively cocked.
Still grinning, Katrina tested the firmness of the mattress by sitting on its edge and bouncing slightly up and down. She felt a bit like a small girl exploring her parent's bedroom for the first time. Then a sudden snuffle and the clattering of claws made her freeze on the spot. Horrified she finally had to realize, that she wasn't as alone in the room as she had believed to be. Nameless fear dripped icy-cold into her stomach; ran down her spine; made her scalp prickle. Slowly the two animals approached, while her heart was pounding and she had stopped breathing. She quailed, unable to move; to flee. Distraught she closed her eyes, even came to terms with her life. That wolf was no ordinary wolf it was a WEREWOLF! Soon it would attack; would rip her to pieces! At that thought something wet touched her hand. It was the nose of the bear-like dog. The young woman opened her eyes and found the huge animal sitting in front of her, obviously eager to be petted. When she then indeed absent-mindedly began to stroke the black fur, the werewolf lowered his head as if he also tried to convince her that he meant no harm.
Soon Katrina overcame her timidity and after a while even allowed her four-legged new friends to properly sniff her. Face, arms, armpits, breasts, belly – werewolf and dog alike greedily explored every bit of body they could reach; absorbed the delicate whiff of fertile femininity in their deep, long breaths. Her promising scent had woken animal instincts. Subtle and yet quite straightforward, the two beasts started to court the woman in their midst; asked her to pet them; catlike rubbed against her legs; nudged expectantly.
Katrina laughed exuberantly when the werewolf eventually licked her ankles, and she had no objections whatsoever when after that his muzzle disappeared completely under the hem of her robes. Of course, she had to grant the same favour to her doggish companion, so suddenly two hot rough tongues were meticulously working their way up her shins. As if in a trance, the young woman closed her eyes, leaned back and tilted her head with a blissful sound. Finally, a nose pushed almost demandingly against her knees; seduced her to let it in. Without thinking twice Katrina opened the path to her womanhood.
Soft fur brushed against the insides of her thighs, while a warm snout pressed firmly against her centre. With intense fervour, the werewolf sniffed at her briefs; eagerly inhaled the sweet and spicy aroma. Automatically Katrina opened her legs a little bit further and thereby made room for the second animal. Sheer excitement flooded her brain when hot puffs soaked through the thin fibre of her underwear and vivified the sensitive skin beneath. Soon the two creatures nudged, pushed and pulled impatiently at her panties. It was the werewolf who first managed to overcome that last, rapidly moistening frontier. Past the fabric he unerringly found her soft opening and dipped his nose in. Intoxicated by the strong odour of her juices, he avidly licked his muzzle while the dog not only pushed his nose into her but his tongue as well. Katrina moaned with pleasure and her back arched under those intense sensations the brute caused.
Again, the two animals changed position. Now it was the werewolf who tasted the sweet nectar hidden inside her depth. More gasps followed! The young woman had started to rub her breasts through the thick fabric of her robes. Suddenly something pointy pricked her side – her wand – and through her foggy mind wafted the thought, that she actually was a witch! Annoyed by her hindering clothes she freed the slender piece of wood to eventually get rid of them after one small swish of magic.
With unconcealed delight the dog and the werewolf accepted that gift and now conquered every little one of those delicious-tasting folds. Instinctively, Katrina bent her legs and spread them as far apart as her body would allow, so that her two lovers could reach as much of her moist cooch as possible. In gratitude, the unequal brothers licked and nibbled the offered flesh with growing devotion; penetrated deep with their tongues into the cave full of rich honey. In lechery, the young woman squirmed, moaning and trembling. She couldn't remember when she ever had felt so much pleasure.
Even when the werewolf at last followed his primal instinct and mounted her, Katrina was neither scared nor revolted! She welcomed his wild thrusts into her as an inevitable consequence of what they had started. It took the beast no more than two minutes and he pressed her pelvis hard with his front legs against his pumping rear. Almost disappointed the young woman watched her passionate gigolo empty himself into her vault, until she suddenly realized that it wasn't over yet. At first, she was irritated, but then she perfectly well understood what was happening to her. Within seconds the anatomical feature of the canine had swollen to its full potential. The two lateral bulges on the lower part of the wolf's glans had almost reached the size of two golf balls lying next to each other and they now stretched her vaginal canal as only an Infant during birth would have done. Katrina groaned in pain and instantly regretted her short-sightedness. Tears started to flow down her cheeks. Why had she been so stupid?
"Oh, dear god!" she cursed, when she found, that the werewolf was just as stuck in her as he would have been in a bitch. The moment he changed position to wait until their connection would end she groaned again. It was just a slight movement inside of her but nevertheless it caused an incredible amount of pain. The young woman whimpered in distress. Immediately the dog was at her side; comforted her; licked her hands, her arms, her breasts, her stomach. His presence helped! It calmed her; made her endure the undiminished pressure in her innermost a lot better.
Eventually the hard flesh softened enough for the werewolf to free himself. Instantly he retreated exhausted into a corner and cleaned his genitals with meticulous thoroughness from the mixture of the union that just had been ended. Meanwhile the dog took care of Katrinas battered honey pot. As if he wanted to do the same for her, he licked her clean until the taste of his companion had completely vanished. That new stimulation made the witch forget what just happened. Lustful gasps escaped her throat and again she contorted her body uncontrollably in the sheets; spread her legs invitingly; willingly presented her twitching plumbing to the bear-sized animal.
The black dog acknowledged this frivolous invitation with excited panting. The half-erect tip of his glans had long been eagerly awaiting its use and was peeking out of its foreskin. Still, the pooch first convinced his soon-to-be mating partner to turn onto her belly. Now she looked like a she-dog in heat; her cunt opening and closing rapidly in waves of pure randiness.
One last time, the brute licked over the wet opening in front of his nose, then it was his turn to satisfy his demands. Uncompromisingly deep he thrusted into her, while her pelvis served him as an anchor. Unlike the werewolf, however, that new admirer remained far more controlled in his movements; deliberately rubbed hard with his penis bone against her narrow walls; increased his pace more slowly. Katrina gasped and buried her face in the sheets. She couldn't help but feeling thrilled at the way the dog humped her.
The immoral affair between dog and woman was not only carefully observed by the werewolf. For some time now, a fourth player had been attending the intimate circle unnoticed. The voyeur hid himself in the hallway; stared randy at the copulating couple. Severus Snape didn't make a single sound; even not dared breathing! His hardened dick was painfully bound by his underpants and when the beast finally reached his climax, it began to twitch with longing.
As soon as she felt the bear-sized hound pumping his cum into her, Katrina instantly tried to escape him. But his tight grip and her disadvantageous position made it impossible for her to succeed.
"Please! Pull it out! Now! I beg you!" she pleaded. Too late! Inexorably fast, the lower part of the dog's glans had expanded. Her sudden fear was more than justified! Soon the pooches knot exceeded that of his wolfish companion distinctively. Too much for Katrina's still young rose! She screamed in horror and pain. The moment he dismounted her to place himself with his back to her, as befits his species, she reared up in agony; tried to escape the tearing sensation in her muscles; panicked. Immediately the werewolf was on the spot, jumped on Katrinas back and forced her to lie still with all his weight; forced her to endure the unalterable situation.
Her tears, her screams, her anguish; the very imagination of her utterly plugged cunt with that bulging hammer of the mutt – the potions master's chest heaved in bursts. Why exactly THAT aroused Snape so much, he did not understand. By now, his underpants hung around his knees and the midsection of his robe had become a tent. As horny as he was, he still didn't dare to lay a hand on himself. If one of the beasts noticed him, he was doomed!
It took a long time until the dog was finally able to escape his sweet prison. So long that Katrina in the meantime had resigned herself to her fate. She moved no more; cried no more! She just lay there paralyzed and waited! Waited, as the werewolf waited on her back. Her insides burned and stung, cramped and throbbed. When her four-legged nemesis had retreated at last, a stream of warm liquid flooded out of her maltreated crack and down her thighs. Katrina was convinced that this time it had to be blood. She did not dare to look; did not dare to move even an inch.
While it was now up to the dog to rest and clean himself from all traces of his amorous adventure, the werewolf slowly jumped off the bed and approached the still over the bed's edge hanging behind. A clear mixture of sperm and her own secretions was still seeping out of Katrinas reddened opening. The beast's nose twitched, it intensely sniffed the air, then it began to lick. The young witch whimpered in exhaustion but no longer had the strength to defend herself against it. She just let it happen; closed her eyes; breathed heavily. Merciless the werewolf's long tongue again and again ran over the sore skin or drilled as deep as possible into her overflowing cup.
Even though Katrina's head was now numb from all the pain she had experienced, her body and nerves still reacted to the continuous stimulation. Soon she could be heard moaning again! Soon she was writhing in new excitement! Soon her labia were as firm and as juicy as an overripe plum!
Suddenly, the dog raised his head in alarm, listened for a moment and got up. Ears and nose working incessantly, it quickly became clear that that faint sound coming from the hallway had not been caused by the wind funnel down a crack in the old wood. Someone was loitering outside! And the dog perfectly well knew who this someone was! Growling, he left the room. Immediately, the salty-spicy musk of another man hit his senses. He searched the almost dark landing, then he discovered the hated wizard pressed into a niche. The rumble from the dog's throat deepened; got more aggressive. He licked his front incisors angrily; pulled the flews back a little further. Caught in the act, Snape raised his hands in silent capitulation and stepped out of his hiding place. For a long moment, the two archenemies looked into each other's eyes – one more than ready to attack, the other trying to defend himself.
"I want to join in!" the potion's master finally murmured with his hands still raised. In honest surprise the hound cocked his ears but was not yet convinced. Still suspicious, he eyed his counterpart; couldn't believe what he had just heard. "Please!" Snape reiterated his request and crossed his arms protectively in front of his chest. The bear-sized dog dropped onto its hind legs with its head tilted; seemed to weigh up. His nostrils flared as he smelled damp fabric and drying cum. A last look at the waiting man in front of him, then he cleared the way. Why not? Shall old Snivels enjoy himself! At least then he also was involved in their doing and couldn't betray them when this was over!
Just as Snape followed the black mutt into the room, the werewolf was ready to mate a second time that evening. Drooling with excitement, he mounted the panting woman; rammed her in wild ecstasy. Again, the impetuous act was over in just a few minutes! Again, the werewolf, pressed deep into her, savoured every second of his outpouring! Again, his knot inside of her swelled up to its full size! Again, within seconds he was inseparably bound! Again, she cried out in pain as he moved into his waiting position!
Breathing just as heavily as Katrina, Snape now inspected that forbidden connection at close range; fascinated by the pulsation and twitching of the shaft visible under the tail held sideways. He could not help it; just had to touch; feel what could only be guessed at from the outside. Inquisitively, his fingers ran through the dark blonde triangle full of curled hair, explored for a moment the almost pea-sized pearl in the middle of her moist lips and then curiously felt the hard lumps stuck inside Katrina's tunnel.
The werewolf let out a soft growl, which made Snape constrain himself to just watching again. As if spellbound, he stared at the two so different rumps facing each other. Then suddenly the object of his burning interest reappeared. For a fraction of a second, he was granted a clear view of the creature's significantly shrunken privates, before they almost completely disappeared into their protective fold of skin. A short, questioning look between the two friends, which the dog answered with the inconspicuous arching of his brows, and the werewolf withdrew exhausted into a corner without even a single hint of objection concerning the newcomer in the bunch.
In a state of arousal, Snape let out an almost animal-like grunt. He couldn't wait to also enjoy that little Hufflepuff; to fuck her hard; to show those two bastards how it was done properly! Neither guilt nor sympathy! If his student willingly agreed to such disreputable practices, why shouldn't it be reasonable to take advantage of her depravity? Nevertheless, he couldn't just screw her and hope for the best! He had to consider his options; had to cautiously prepare. While their animal form protected the true identity of the other two wizards, HIS on the other hand immediately would be revealed if he wasn't careful enough. There was but one solution to protect himself from being recognized – to blindfold her!
When Katrina still recovered from the last painful encounter with the werewolf, suddenly a thin cloth covered her eyes like a second skin. Frightened, she tried to free herself; tried to pull it off. In vain! The flimsy fabric remained where it was and blinded her completely! Still fighting, her panicky brain realized in a flash that this had to be a spell! That thought cleared her mind! Her wand! She just had to find her wand! Awkwardly she felt for the so much needed piece of wood! The black dog, however, was faster! Before Katrina could even come close to her forgotten on the mattress laying saviour, he had already grabbed it in silence and brought it out of her reach.
Snape gave his student a couple of minutes to accept the changed circumstances. Naked and ready he waited for her to calm down. Finally, she indeed stopped her fruitless search; resignedly knelt on the bed. One last look and the potion's master began. With a determined push he manoeuvred her onto her back, pulled her body close to the edge of the mattress and then spread her legs.
"No! Please! Don't!" she whined desperately, and tears welled up in her eyes. Of course, he just could have done what she believed he would do to her; he just could have raped her. Alas, that brute act of force wasn't the kind of game Snape was into. What would be the fun in hearing her cry the whole time? Yes, he normally liked to do it hard, but the pleasurable way; the way BOTH could enjoy.
The vertical line between his eyebrows deepened, when he examined the mess dog and werewolf had caused. Her usually pink flesh was now red, sore and bruised from all the previous licking and humping. No way Snape could possibly make her play along as long as her cunt looked like that! So, he grabbed his wand and first cured her injuries, before he started to rekindle that lecherous fire her ordeal had eventually kicked out.
Snape had to be patient! It took ages for Katrina to feel aroused again. His mere presence made her anxious and even though the pain in her sanctum was gone by now, she still didn't like to be touched. Nevertheless, his fingers were as merciless and continuous as the beast's tongues had been. He massaged her; stimulated her, until at long last his efforts were successful and prurient moans of sweet pleasure echoed through the room once more. Her expectantly convulsing twadge was dripping wet and glistened magnificently in the fading light of the slowly dying fire. His time finally had come!
Like a Neanderthal, Snape pulled her slim hips towards him to sink deep into that eagerly waiting flower. He closed his eyes, panting, as he thrusted. Hard and harder! Fast and faster! Her tight pussy felt so good! He fucked her with all his might; grunted like a breeding boar. The slapping of his balls and her choppy moans fused together in synchronized harmony.
The moment he had started to take her, Katrina had immediately surrendered to his irresistible dominance; became a willing concubine to that sheer force of nature! Werewolf and dog were amazed at the hidden talents of their detested ally. The two friends had to admit without envy that the potion's master obviously knew what he was doing. It seemed, he hit precisely the right spot! Katrina's orgiastic screams were striking proof! Again and again, she climaxed in wild convulsions; writhed and stretched in unbridled lust, until he finally discharged himself with a deep, predatory rumble into her rhythmically around his hard dick contracting cooch.
Dazed, the young woman gasped for air and desperately tried to think straight again. Never before she had had sex like that – uncompromising but not brutal at all, fierce but by no means unpleasant. And he had been so persistent! Nothing she had experienced with her classmates so far could be compared to THAT! Katrina listened intently! A vague feeling told her, that she knew that man. It was how he moved, his grunts, even his smell. All that seemed somehow familiar and yet she couldn't put her finger on it. Suddenly she stopped dead in her thoughts! She wasn't blindfolded for no reason! What would happen, if she identified him and he found out that she had? Another terrifying thought came to her mind. What about the werewolf? What about the dog?
With a deep breath she tried to fight the emerging fear; steadied herself! The one thing she wanted most, was to get out of here. But as if he could read her mind, the werewolf suddenly reappeared and pushed his muzzle demandingly between her thighs.
"No! Not again! Stop it!" Katrina desperately tried to push his head away. Nevertheless, she had nothing to oppose him. Once the devilish beast had managed to reach her centre, it started his fervent licking. Against her will, she had to capitulate. The objections from her brain were instantly overruled when her body reacted exactly as nature had created it to. The one-oh-one of mating repeated itself. Seduction, arousal, readiness and action. Soon Katrina couldn't help anymore but to voluntarily offer her wide-open crack to the animal between her legs.
While the werewolf continued his submission, dog and man suddenly began to argue in silence. Snape had recovered surprisingly fast from his encounter with the Hufflepuff and now demanded a second go, before she was in pain again and had to be healed. The efforts to renew her appetite afterwords had been painstaking and annoying. The black canine, however, was unwilling to agree to Snapes unspoken wish. He just jerked his head sternly in the direction of his four-legged companion. It was HIS turn now! The potion's master though wasn't about to give in that easy. Angrily the dog bared its teeth, but Snape showed not a single sign of intimidation at all. As cool as ice he first pointed to the furious hound, then tapped his own chest and finally included the woman by holding up three fingers. Immediately the exposed fangs disappeared and within seconds the bear-sized dog transformed into a thin, dark-haired man – Sirius Black.
Just a few moments later the werewolf also got inspired by Snapes idea and agreed to take the back seat. He stepped aside to make room for the two wizards. Without much introduction the Animagus lifted Katrina off the bed, carried her to a nearby chair, sat her onto his lap and let gravity do its duty. The young woman let out a relieved moan when she felt the erect human penis slide in deeper and deeper until it completely filled her. No werewolf this time! Instinctively, she began to ride that new cock. It was different! Another man! Katrina didn't care! As long as the damn beast stayed away from her! Her muscles contracted around his phallus, and she came; closed her eyes beneath her blindfold; whimpered in ecstasy.
Sirius nearly got carried away but at the last possible moment he got a grip on himself and stopped her from proceeding. He spread his legs wide and pulled his pelvis a bit back, so that her arse now dropped an inch between his thighs. In that new position he held her tight and waited for Snape to do his part.
While Katrina now was firmly pressed against the body she was sitting on, behind her, the potion's master knelt down in a swift move and gently squeezed one of the round cheeks in front of him. Then his fingers began their work. Casually, yet determined, they ran along her butt crack, until they got to her occupied pussy. For a split-second Snape touched the hard flesh, before he returned to her second opening. A trail of fluid followed his fingers, which he now distributed in circular motions around the small hole. One last look into Sirius' eyes and he carefully pushed his thumb through that tightly closed muscle ring. At once Katrina wailed in horror and started to struggle. Another look between the two wizards, this time consultative! Evidently their young playmate was still an anal virgin. Should they stop? No! They consented to continue their game. There always was a first time at some point! So, why shouldn't it be today?
Sure, that his ally would hold her tight, Snape intensified his doing after that brief pause. The woman screamed and cursed, yet the well lubricated thumb broke her resistance over and over again, until it finally slipped in and out with ease. She was ready for him and the potion's master was ready for her! For the last time he spat onto his penis glans and rubbed the fluid over his stiff cock, then he replaced his thumb. When her professor bit by bit conquered the hot tightness of her arse, Katrina buckled like a bronco.
Snape took it slow; gave his student time to get used to that new feeling. He wanted her to enjoy it; wanted her to relax. Nevertheless, the moment he felt Sirius' dick through the thin wall that separated these two openings, he couldn't help but to thrust the last inch into her in one go. She groaned and tried to escape him, so he gave her a short break before he really moved.
Katrina was in tears when the two men eventually started their amazingly well-choreographed dance inside of her. One forward, the other backwards, then vice versa! After beginning slowly, they picked up speed; adjusted their rhythm after every single thrust. Regardless of their enmity, this cooperation between Snape and Sirius surprisingly went like clockwork! The young woman on the other hand still struggled with being fucked by two men at once. Had somebody told her about such practices, she would have considered them anatomically impossible and if she had had the choice, she rather would've refrained from finding out, that it actually worked.
After a few minutes though, the witch suddenly changed her opinion. The intense sensations caused by her to the brim filled holes overwhelmed her and at long last made her appreciate those relentless lovers. The moment she gasped in lechery Sirius loosened his grip. After Katrina now loudly proclaimed, that she took a liking to that exquisite game of theirs, binding her was no longer necessary. By the way, Sirius knew much better things to do with his hands. Apparently, the potion's master thought so, too. Soon their fingers not only met on those firm breasts but also started fighting for the prerogative over the Hufflepuff's swollen clit in growing ecstasy.
The next, all-encompassing orgasm shook Katrina, and this time she dragged the Animagus with her. Passionately sighing, he welcomed the feeling of being milked by her pulsating narrowness 'til the very last drop. While Sirius already threw his head back in deep satisfaction, it took a few more thrusts for Snape to also climax. As soon as the two men withdrew their now nearly flaccid dicks, milky-white cum started to seep out of both openings.
Too much for the werewolf! Aroused beyond measure by the previous spectacle, he couldn't restrain himself any longer. With a furious growl he approached his friend and the woman on his lap. Sirius reacted in a blink of an eye. He pushed his pelvis forward, closed his legs and offered Katrina's still slightly contracting pussy to the sex-crazed animal. As if out of his mind, the werewolf tried to mount; thrust into that glistening temptation. Alas, due to her position, he missed several times, until Snape grabbed the tip of his glans and directed the penis bone upwards at the right angle. Only then, the drooling creature succeeded in penetrating the student's cunt. Immediately he humped her uncontrollably but still couldn't find a proper grip. The moment she moved to shake him off, he slipped out again and in that very moment spread his semen onto the aged floor. It was over!
The werewolf stood frozen to the spot, panting, while small amounts of clear liquid squirted incessantly from his now fully visible glans. Then, he suddenly fled into a corner and started to lick that almost entirely erect dilemma between his hint legs. Curious Snape followed and watched as the creature ran his tongue over the thick knots again and again, almost frantically. In an instant the sensitive flesh looked sore, and the soft whimpering turned into a heartbreaking whine.
"Stop licking!" Snape murmured, but these words went unnoticed. As if possessed, the werewolf continued to massacre his privates; yes, he even began to bite them. The potion's master had seen enough. He ended the beast's suffering with a silent decongestion spell and afterwards healed the by now bleeding skin. The werewolf welcomed this act of unexpected mercy with grateful astonishment. Exhausted, he laid his head onto his paws, closed his eyes and allowed himself to catch his breath.
Unnoticed, Katrina and Sirius had returned to the bed by now. After Snape and his friend being occupied by the aftermath of the werewolf's failed mating attempt, the Animagus had taken the opportunity to claim the witch all for himself. To his huge disappointment she wasn't very fond of him shagging her again. The threesome had been exhausting for her, so her body ignored his tender kisses and gentle caressing. At least for a while! Sirius relentlessly continued his fondling until he finally got her to the point of reacting again.
The moment Snape turned away from the werewolf he found Katrina trembling once more with pleasure. He didn't complain, neither did the witch. Bedazzled by her new awoken lust she stopped thinking about how often something had thrusted or cummed into her during the past hours. With a voluptuous sound she rolled onto her stomach and stretched her wet, expectantly twitching middle into the air. It took less than two seconds, and her obvious wish was granted. Sirius grabbed her hips and then he screwed her the way he earlier had screwed her as a dog.
Once more Snape enjoyed the role as a voyeur. Wanking he knelt next to the fornicating pair; shamelessly enjoying the intoxicating scene. The potion's master absorbed every detail! The sound of skin slapping onto skin mixed together with all the other sounds of ecstatic lovemaking into a polyphonic canon, the way Black's fingers dug deep into the pale flesh, the small waves running through her butt with each thrust, the bobbing of her small, firm breasts, the face distorted in lust.
Not only Snape was watching! The overstimulating crescendo on the bed yet again drove the werewolf out of his mind. With foaming muzzle, he panted fast; followed every movement, no matter how small. His foreskin, the extended tip of his glans, his whole abdomen twitched. In extreme distress, he finally let out an almost human whimper. Breathing heavily, Sirius paused and looked around. Just as his companion had voluntarily made room for him earlier that night, he now stepped aside for the werewolf.
Before Katrina really understood what had just happened, the animal was already inside of her; rammed her with all his might; stepped from one hind leg to the other in a wild frenzy. The sheer force of this act made Snape's and Sirius' balls twitch in equal measure. Faster and faster the two wizards jerked their hard cocks and at the same time fingered Katrina's highly sensitive pleasure button with their free hands.
When the werewolf finally discharged the main portion of his semen in a last vicious thrust, Snape and Sirius also found salvation. Panting and grunting, they spread their white cum almost simultaneously in a wild web of thin lines and individual dots on the body lying between them. For a brief moment, they proudly examined their work, then sank down next to the hoarsely whimpering woman in exhaustion.
Neither for Katrina nor for her four-legged admirer an option! Woman and beast remained trapped in their uncomfortable positions, waiting for the aftermath of their merging to fade away — he almost impatient, she desperately sobbing. Not only was the increasing pain in her abdomen causing Katrina serious nausea by now, the slowly drying sperm on her back also made her feel dirty; unclean; used! She longed to be able to wash it off; longed to be able to wash off the whole NIGHT! She just wanted all that to stop; wanted to get away! The young woman thought of her cozy bed, orphaned somewhere in the bowels of the castle, waiting for her in vain. If only she had never come!
A new crying fit shook her and suddenly everything began to spin in her head. At that very moment, the werewolf decided that it was enough! His penis had stopped pumping, and the blood gradually drained away. The knot on the lower part of his glans already had softened and was smaller, but still too big to pull it out. In growing impatience, he turned to his rear; licked the visible bit of his shaft. He didn't want to wait any longer! With a single, violent jerk he eventually freed himself from her vagina! Instantly, a stabbing pain flashed through Katrina's genitals, as if something glowing red had been thrusted into her. She shrieked in uncomparable anguish; pressed her hands against her bleeding minge. The next moment she slumped like a puppet whose strings had been cut and fainted.
Angrily, Snape and Sirius glared at the guilty-looking werewolf. For almost a minute no one said a word, but the unspoken accusation remained clearly visible in their eyes. That damn idiot would have had to endure his imprisonment only for a few more moments!
"So much for that!" Snape finally hissed and looked at the unconscious woman. "We have to think carefully about what we do now! If Dumbledore ever finds out...!" He broke off with a distinct shudder and folded his arms over his bare chest.
"How should he? WE won't tell!" Sirius growled threateningly, mirroring the posture of his counterpart. The potion's masters mouth curled in provocative sarcasm.
"Are you so sure about that?" he shot. "Not that the four-legged flea bag over there suddenly feels the need to confess when he is human again!" Those words made Sirius remember why he hated that man so much. He grinded his teeth angrily.
"Don't worry about Moony! He won't say a word! I rather believe that YOU will stab us in the back as soon as it's to your advantage!" the Animagus growled. Snape let out a joyless laugh.
"Is that so?" He shook his head disapprovingly. "I thought your plan was to let me join the game so that I could NOT betray you!" Again, he shook his head, this time amused. "In retrospect, not that a good idea, was it? But don't mind! Your brain obviously was stuck somewhere else!" Snape raised his hand in conciliation, as Sirius was about to react rudely to that open provocation. "It's okay! Calm down!" snapped the potion's master. In fact, the Animagus abandoned his biting retort and instead only snorted in disgust.
"So!" he finally barked aggressively and took a threatening step closer.
"So what?" repeated Snape stoically and held the hateful glaze. "That you don't trust me, Black, is YOUR problem, not mine! Deal with it!" He turned away. Just as Sirius was about to grab the black-haired opponent by the shoulder to continue the finished discussion in a more physical way, a horrible howl came from the corner where the werewolf was lying. Suddenly the animal began to contort in unspeakable agony – morning dawned. As if rooted to the spot, the two wizards stared side by side at the beast during it changed back into a human being.
A few minutes later, an exhausted-looking Remus Lupin knelt on the ground. He watched his company vigilantly, then his gaze fell on the bed. Regret flickered in his brown eyes.
"I'm so sorry!" he croaked hoarsely, stood up and looked at the damage he had just caused, when the fading moon had made the werewolf impatient. As he gently touched the still with blood and his secretion stained skin, he at once started to pant, while the limp piece of flesh dangling between his legs began to stiffen. Snape laughed out with a predatory grin.
"So much for conscience and morals!" He looked at his colleague with amusement, then suddenly raised his eyebrows. "Do you also want to fuck her?" he asked plainly. Lupin stared in shock at the potion's master's suggestion. Although, his body was already giving the unmistakable answer. "I'll take that as a yes!" Snape noted with a business-like voice and pushed the professor for Defence against the Dark Arts aside. "Wait!" he muttered. Then he took care of Katrina's injuries. Soon the blood had disappeared, and the skin of her pussy looked rose red again. When Snape was done, the young woman was draped on her back, her legs spread wide open and her cooch fully exposed. Lupin gasped excitedly and his sword was ready for battle. "Wait!" repeated the potion's master. "You don't wanna screw an unconscious woman, or do you?" Lupin somehow ashamed shook his head. Another spell and Katrina began to stir.
At first only her hand twitched, then her breaths deepened and finally she moved her entire body in a daze. The potion's master warningly put a finger to his lips. Lupin acknowledged that gesture with an understanding nod, while his gaze remained fixedly on the woman who now was slowly sitting up. He hesitated; swallowed; suddenly seemed insecure. How much he wanted her could be seen in the demanding pulse of his hard dick and yet he just stood there; panted softly and stared. Snape decided to give his colleague some more help and flicked his wand again.
Out of the blue a deep desire for sex took a hold of Katrina and she started to moan fervently. Blinded by lust, she masturbated feverishly; tried to satisfy herself with her fingers, where only a man could help. And the saving angel already was on the spot! Gasping hornily, Lupin seized her legs, threw them over his shoulders and then her sweet tightness embraced him; massaged him. He enjoyed the feeling of her muscles convulsing around him; enjoyed her lust. Unlike the werewolf, the man took his time; played in and with her; squeezed her breasts; pressed her little pearl.
Once more, cries of pleasure echoed through the Shrieking Shack. Even Snape and Sirius let themselves get carried away again by the highly erotic situation. Their fingers literally flew over the velvety hardness of their newly awoken dicks, while Lupin thrusted harder and faster. The quartet of heavy panting grew louder; grew more intense. Four bodies writhed ecstatically in the faint light of the glowing ash from the fireplace, until they all together fell into a world of a thousand stars.
Trembling and breathing heavily, Katrina lay flat on the mattress, her pussy still twitching uncontrollably from her orgasm she just had experienced. She no longer understood the world! What was happening to her? Vaguely she felt the narrow trickle of milky-white fluid slowly running down the insides of her thighs. So, it wasn't a dream! She indeed had had sex again! How on earth could she suddenly have behaved like a bitch in heat, after what previously had happened to her? Tears soaked the black fabric still covering her eyes and deeply ashamed of herself, she curled into a fetal position. Only then she noticed the sticky liquid on her stomach and on her breasts. That was too much for her! In desperate sobs the young woman began to shake violently.
"Now that's enough!" Snape growled, after he had finally sent his student back into a well-deserved fainting. "We have to stop!" As if to reinforce his words, the woman on the bed and her three lovers in front of it were dressed the next moment. A last look at the now calmly breathing Hufflepuff and the professor for Potions turned to his accomplices. Before he could say anything, however, Sirius beat him to it.
"Nice little tricks, you have up your sleeve! Where did you learn something like that?" he poked with a mixture of recognition and the mere desire to simply provoke. Snape answered with a superior curl of his lips.
"You have to join the Deatheaters, if you really wanna know! I am surprised, Black! For the first time you seem to understand, that sometimes the other side also holds useful knowledge worth acquiring!" The potion's master folded his arms in front of his chest. "Considering the fact that time is breathing down our necks right now, let's postpone THAT talk until later! We rather shall think about what should happen to HER!" He jerked his head in Katrina's direction.
"I'd say it all depends on whether she enjoyed the night with us!" Sirius grinned lightly. Lupin rolled his eyes.
"Don't you dare suggesting that we just ask her!" Due to his best friend's words Sirius shrugged incomprehensible.
"And why not? If things go well, we could have lots of fun for the rest of the school year!" The Animagus winked with a grin, then shrugged again. "Otherwise, we still can come up with something else!" Lupin's eyes widened and he grimaced thoughtfully. For a split second, what his buddy had just suggested made perfect sense. His weighing of pros and cons was abruptly interrupted by a deeply disapproving snort.
"Are you completely out of your mind, Black?" Snape snarled stunned. "First you insinuate that I would use the first opportunity to blackmail you and the werewolf with something I am also up to my neck and now you propose to put our fate into the hands of a traumatized eighteen-year-old?! What's wrong with you? Do you tick-infested bed rug occasionally think, or do you have that big head of yours just to show off?!" Lupin courageously grabbed Sirius' arm before he could leap at his former schoolmate.
"You think you're so clever, Snivellus, aren't you? But luckily you ugly slimeball don't rule! The majority decides!" the Animagus growled, then turned to his best friend. "Don't worry, Remus! I will control myself for now! He's an utter annoyance, but I can bear his insufferable presence!" Sirius closed his eyes for a moment and took a deep breath, then he also crossed his arms in front of his chest. "Let's vote! I say we'll ask her! It's up to you! What do we do?" A waiting look followed in Lupin's direction, which he suddenly returned almost apologetically.
"Severus is partially right! She IS traumatized! The things, we have done to her were ... " The professor searched for the right words. "Near the knuckle! Sorry old friend! But the risk that she'll just say what we wanna hear to get away as quickly as possible, is simply too high. My gut tells me we've overegged the pudding! If she tells anyone what a black dog, a werewolf and a couple of men did to her in the Shrieking Shag, we are DONE! From our own experience, we know how well the rumour mill at Hogwarts is lubricated! It would be only a matter of time and that story finds ears, who know what to do with it!" Lupin now also crossed his arms in front of his chest. "I say we'll make sure she doesn't remember US or the night AT ALL!"
