The room looked very much like an ordinary classroom. One wall covered in cubs paintings, happy pictures in bright colors. But the air was filled with scared cries and sobbs. There were six chairs arranged so all had a good view on a small platform, placed, where the teachers desk would normally be. On each chair sat a young cub, their arms and legs secured with thick leather straps. Each one a different species, but all looked equally terrified. A click echoed through the room. Someone opened the door. Faint voices became audible. "... here it is mam. All has been arranged as you requested. I hope you are pleased with the selection of the specimen, we tried to supply an interesting mix." "Thank you! You can leave now." The second voice belonged to a sergal woman, her fur white as snow. She entered the room, a polar bear girl following her, closing the door behind them and locking it. She pulled the keys from the lock and handed it to the woman. "Good morning class. I'm Lucy and I'm your teacher for today." The woman waited for a response from the gathered cubs. "First lecture of today: It's rude not to greet your teacher. So again. I’m Lucy.” “Hello Lucy!” The cubs responded in union, their voices shaking with fear. Her gaze wandered over the cubs in front of her. On the most left chair sat an armadillo boy, about 7 or 8 years old. He wore short brown pants and a white t-shirt, so the thick scales covering most of his body were visible on his arms, legs and his tail. Next to him sat a green scaled lizard, roughly the same age. His clothes in a color matching his scales, making it appear like he was fully nude, on the first glimpse. Her gaze lingered a bit over his cute, slender body, following the sleek, sexy curves of the reptile. The next cub was a cute canary, the yellow feathers of his face soaked in tears, as he looked at Lucy with watered eyes. He was a bit smaller as the others, but he had the same, fearful look as them. The fourth was a furred dragon, his fur the same innocent white as Lucys (even if the sergal wasn’t by any means, innocent). The last cub was a shark. In addition to the straps, he had been gagged with a muzzle, preventing the cub from putting it’s sharp teeth to use. “Who wants to go first?”


The fox girl squirmed, as Lucy pressed her down on the hard surface of the plattform. None of the kids had shown initiative. But Lucy had decided to start with something vanilla. The girl struggled, as the sergal pulled down her pants and underwear, revealing her cute little cunny. "This is what people call a vagina, or pussy." She explained to the kids. The fox girl gasped as the sergal pushed two fingers inside her, spreading her cunt. “But the term actually describes the tunnel connecting the outer parts, called the vulva, with her uterus.” She pushed deeper into the girl, until her fingers had reached her cervix. “At its end is a muscular ring, normally blocking access to the uterus.” Lucy pulled her, now slime covered, fingers back. She opened the zipper on her pants and pulled out her already stiff cock. It was stunning, 20 inches long and shaped similar to that of a dolphin. She couldn’t help herself but smile at the sight of the cub's surprised looks. She enjoyed the attention, especially from the boys, making sure all had a good view, as she aligned herself with the foxes tiny slit. "Let's continue with the practical demonstration!” She started pushing into the young vulpines body. At first it was only the thin tip of her cock, sliding into that tight, virgin depths. She tried to take it slow, so the girl could adjust to her size, at least for now. The fox squeaked, when the herms cock hit her cervix. "I have now reached the end of her vagina." She stopped pushing. "I could now stimulate her by pulling back and pushing in again, rubbing against the sensitive inside of her vagina, but the easier way is to directly stimulate her clitoris." She reached down, rubbing her thumb over the tiny bump at the top of the girls pussy. The vixen squirmed harder, as Lucy continued to rub her, until she let out a loud scream, as the sergal had pinched her tiny clit. "As demonstrated, the clitoris is a very sensitive body part." She pressed harder and the fox girl screamed again, this time even louder. "But it's not the only part that's sensitive and should be handled with care." She pulled her hips back a bit and hit girls bottom with her full strength, easily tearing through her cervix, slamming into her womb. The third scream was ear shattering, as the fox girls body started convulsing. But Lucy's iron grip kept her in place, as she pushed further into the fox. "I have now ripped through her cervix and am currently inside her uterus." She pushed again, breaking through the top of the vixens womb into her intestines. Pushing further and further, ripping and tearing her insides in the process. The girls whole body was now spasming, foam forming in her mouth. Lucy closed her hands around the cubs fragile neck, placing her thumbs on her windpipe, pressing violently into it. With an audible crack the hard gristle gave in and her fingers sank into the girl's neck. The foxes body thrashed on the plattform, but Lucy's strong gripp kept her in place until the spasms calmed down. "And that kids, is what a person being strangled looks like. You may pay special attention to her tongue, as it will quickly turn blue, as her body is lacking oxygen." After about two or three minutes it was over. The vixen wasn't moving anymore. Her eyes open and dead. "Thank you for your participation in this demonstration." Lucy pulled her cock from the girls depths and a rush of blood splattered from her used cunt to the floor. "Nicoletta!" She turned to the polar bear cub, still waiting in the corner of the room. "Could you please get her off the demonstration area?" The girl didn't say a word, just nodded. She moved over to the dead fox, grabbed it by its ankles and dragged it to a corner of the room. Leaving a long, bloody trail on the floor. "Thank you… who's next?"


The armadillo boy was visibly shaking, being pushed down on the same spot, the fox girl had met her cruel end only minutes ago. Lucy had pulled him to his knees, his upper body resting on the floor, his butt lifted into the air. "The next I want to show you is what is called anal sex." She slid a finger down the boy's back, passt his swaying tail, until it had reached his little pucker. "In contrast to the vagina, the anus by nature is not intended to be penetrated." The sergal poked around inside the armadillo’s back until she found the right spot. "But men and women can still get pleasure from it.” She started rubbing against the thin fabric above the boy's prostate, causing the boy to moan from the stimulation. But she quickly pulled her fingers out, aligning her, cock, still covered in the fox girls blood, with the boy's pucker. “Normally you should use lots of lubrication.” The boy clenched his teeth, as he felt her pressing against his sphincter, increasing steadily, until tearing into him. He screamed, as the Sergal’s cock continued to rip him open further and further. Blood ran down his crack, over his balls and cock, dripping from it’s tip to the ground. But Lucy kept pushing deeper and deeper, feeling the boy squirm, his guts twitching, as they tried to push back the unwanted intruder. Tears ran down the armadillos cheeks, as he was overwhelmed by the pain, but at the same time he felt something else. Lucy had slid one hand between the boy’s legs and found, to her own surprise, the armadillo’s hard cock. She grabbed it and started stroking it, the blood still running down from his ass, acting as lubrication. The mixture of sensations was too much for the young boy's brain. He didn't try to escape, he didn't try to fight her. He only lay there, trembling in pain, fear and lust. The boy convulsed, when she hit the first turn of his bowels. He tip poking against the soft wall. Lucy looked down on the 10 inches of her cock still outside the armadillo's body. "You have to be careful not to damage the fragile walls, or even tear through them." She pushed forward, breaking through the boys bowels, stabbing into his innards. The boy screeched like banshee, but Lucy didn't really care. To her the Armadillo was just another toy to play with and throw away after it was broken. The boy quickly lost his voice, coughing, as he tried to get air again. But Lucy gave Nicoletta a sign and the bear cub brought over a thin wire and carefully wrapped it around the boys neck, before handing the Sergal the handles attached to the ends. Lucy checked that the wire was positioned correctly, running through the thin gap between the armadillo's armor plates and around his soft throat. The boy whimpered, but it quickly turned into gagging, as Lucy pulled on the handles. The wire cutting into his skin, slowly compressing his windpipe and carotid arteries. The other kids watched in shock, as their classmate's mouth opened to gasp for air, but couldn't get any, his jaw snapping on the air. He threw his head around in panik, trying to bite the wire, but Lucy made sure to keep it out of range of the boy. Quickly his struggles got weaker. "On more dangerous specimens, like this one, it's recommended to use a garotte for strangling, as it minimizes the risk of getting hurt." The boy was in his death throes, his whole body convulsing on the plattform. The certainty, that this boy will soon be gone by her hands and his sphincter spasming around her cock pushed the sergal to her second orgasm of the day. As she filled the boy's destroyed ass with her cum, she yanked the wires hard resulting in a crunch from the boy's neck, as it was crushed by the steel. She let go of the garotte and the armadillo's head fell forward, hitting the floor. His dead eyes staring at the remaining cubs.


After Nicoletta had removed the armadillo's corpse, the canary was next. He tried to fight Lucy's strong grip, but it was a lost cause. He ended up on his back, laying on the same spot, the other two cubs had died, knowing it was his fate too. He had been crying the whole time, the feathers on his face soaked with tears. "Stop. Why are you doing this?" He whimpered. "Have I allowed you to talk?" Lucy lifted her hand, slapping the sobbing boy. She felt the boy's soft feathers on her skin, as her hand collided with the bird's cheek, the force of the hit throwing his head around. "N...n...no" "Good. Now keep still, or this will hurt even more." She quickly got rid of the cubs clothes, pulling and tearing them from his body, until he was butt naked. Her fingers roamed the fragile body, crawling deeper to his private area. The pink ring of his cloaca was barely visible under his feathers, but the sergal plunged her fingers into the virgin depths, resulting in a loud squeak from the boy, as she invaded this part of his body. He never had anything in there, never even thought about that, but he knew, that it was not a place for the sergals long fingers with the sharp claws. They ran over the soft sensitive tissue of the boys cloaca, causing great discomfort for the young bird. "Most male birds don't possess a penis. They just have this cute little hole, they press up against the woman's hole, and squirt their cum out of." Lucy pushed in even deeper, until she had reached the back of the cavity. She pulled her finger back, scratching along the sensitive inside, cutting into the warm, quivering walls. "Let's see how deep I can go this time." She leaned over the boy, staring into his fear filled eyes, an evil grin on her face. Once more, she aligned her cock, pointing the tip at the bird's twitching hole, thinking about which way to end the kid's life. They all could see the birds face tense up, as Lucy pushed into him. The boy's eyes snapped open and he let out a high pitched scream, as the sergals cock drilled into his insides, breaking the thin walls of his cloaca. "As you all can clearly see, our little friend is in great pain and distress. That's because his little hole is only a few inches deep and not meant to be penetrated." The boys voice cracked, as she tore into his insides. He flailed his feathered arms, but there was no way he could overcome Lucy's strong gripp, pressing him onto the bloody floor. His hands grabbed her Arm, the birds talons digging into her skin. The sergal hissed and pulled her arm back, thin streams of red blood soaking her snow white fur. Feeling her grip loosen, the boy made an attempt to crawl away from her, her cock slipping from his torn, bleeding depths. But only fractions of an inch before he was free, her hands gripped the feathers on his chest, her claws digging into the skin and flesh beneath them, pulling him back, spearing him on her murder cock. Everyone in the room could hear his insides rip and tear, as his off tone screams turned into bloody gurgles. "I have now broken deep into his intestines, probably damaged his lounges in the process." His body convulsed, as he coughed out blood, soaking his own chest. "Let's see what we have done to our little friend. Nicoletta sweety, would you please hand me my tools." The polar bear girl had watched everything from her corner of the room, but now came over, handing Lucy a sharp knife. The boy was already very weak, but his eyes still gazed at the large shining blade, slowly descending towards his light blue feathered belly. She made one long cut, from his chest to his crotch. His body was trembling. Blood spilled out of the bird's belly, tinting his blue and green feathers in a dark red. And between all the blood and gore, the remaining, terrified cubs could see Lucy's cock rise from the boys destroyed innards, spurting white cum over his blood soaked, now still, body. It was by far the messiest kill, but also the most spectacular. "That's what you get for causing trouble!"
