Light footsteps echo down the hall, a hall that's just a little quieter than it should be, a little less populated. Adrian smiles contently to himself as he makes his way to his next class: Biology.

It's not a long walk from his last massacre, but even so he gets to hear the sweet, beautiful song of his deeds cascading upon others.

"Ugh, you gotta be kidding me," a girl standing by her locker says to no one in particular, "I can maybe understand during class, but the bell just rung! Check your messages, girl."

"Huh?" an otter passing by prompts, overhearing.

"I think Alyssa is ghosting me. She won't answer my damn texts," she explains.

"That's rough," the passerby says over her shoulder as she continues on her way to class. She stops at a classroom door and enters. It's the same as Adrian's destination. Unfortunate for her.

The mouse arrives just as the bell rings, flipping his forged card to activate the silent lockdown as he enters. He perks up and rubs his hands together when he gets a look at the biology teacher. She's a cougar in multiple senses, a mountain lion on the older side of things, and she's quite obviously pregnant.

The teacher gives him a look, more exhaustion in her eyes than contempt. She doesn't say anything, but Adrian can tell she doesn't like being oogled and slobbered over like a juicy ham. He makes direct eye contact with the meeting point between her breasts and baby bump for the next few seconds regardless as he makes his way to his seat at the back of the room. It's one of the smaller classes all things considered with only a few rows of desks.

Adrian doesn't bother listening as the cougar gets up to talk. "I am Mrs. Sibeil" goes in one ear and out the other, as does "I'm aware it's the first day of the year. Since none of you are settled in and comfortable yet anyway and I'd really prefer to just get this over with, we'll be covering our reproductive unit today in its entirety."

His attention is instead on a mongoose in the seat next to him. She sits staring blankly ahead, tapping her pencil idly on the desk. The predatory misfit can't help but be appetized by her, eyeing her long hair and admittedly small breasts but ones that are well-developed for a thirteen-year-old.

Adrian finds himself thinking about how nice she'd feel to devour, to melt, to break. It isn't hard for him to work himself up over her and become aroused enough for his three-foot cock to escape his pants on its own. It smacks against the bottom of his desk with a small thud, but fortunately nobody seems to pay it any mind. It brushes against the hair of the girl in front of him where it drapes over the back of her chair, but she only gives him a quick glance over her shoulder before turning back around and trying not to draw attention to herself.

Mrs. Sibeil is currently occupied reading the day's lesson plan. Intentionally or not, all eyes are turned away from the mouse, so Adrian, ever lacking in the inhibition department, decides it's the perfect time to help himself to his classmate.

SCHLLLLRK

It all happens so quickly for Kayla. One moment she's in her seat, paying attention to nothing in particular. The next, a small hand is covering her mouth and pulling her from her chair, and before she can make a sound, her head has been stuffed somewhere warm and slick.

Adrian lets out the quietest moan he can as he slides the girl into his cock. He reaches beneath his desk to grip under her arms with his hands while guiding her lower body with his feet. Kayla is forced deeper inside as she begins too late to struggle, not yet realizing what's even happening to her.

SHHLLLK ULK

The cruel mouse is quick and efficient in devouring the mongoose. She's halfway inside in only a short couple seconds. Though she manages to kick the chair ahead of Adrian's desk with one leg, she's been pulled all the way inside by the time anyone turns to look. Adrian uses his legs to tuck his shaft closer to himself so it doesn't poke out much from under the desk. He has no worries of facing consequences for his actions himself, but he doesn't want to alarm his prey and allow them to escape.

SLOSH GLRRRG

The mouse's squirming, churning nuts aren't the quietest or most subtle, but it's evident that of the girls closeby who notice their absent classmate, none want to be the one to speak out against the pred.

In fact, Adrian doesn't stir from his pleasure-driven stupor until he overhears a particular exchange.

"For an introduction, as if kids your age haven't learned it one way or another these days, sexual reproduction primarily relies on a pair with respective male and female genitalia copulating- Yes, Samantha?" the teacher looks to an otter who raises her hand.

"But what about lesbians? I'm one of those, and my girlfriend and I want to have a baby one day," she says surprisingly plainly. She seems unaware of the eyes falling upon her of her classmates who have had more time on the internet and learned a lot more about certain things than she has.

"Artificial insemination is a viable alternative," Mrs. Sibeil replies, an informative answer if not delivered in a dry tone.

"You have a girlfriend?" one of her classmates asks quietly.

"Yeah! Kayla is my girlfriend. She's right over-" Samantha notices the distinct lack of a mongoose seated in the conspicuously empty seat right beside Adrian.

The girl she was talking to opens her mouth to say something, but with an intimidating glare from Adrian holds her tongue. Samantha is rather slow on the uptake as she walks over near the mouse's desk, realizing too late that he has squirming, gurgling nuts large enough for a person to be trapped inside and is rock solid.

"Have you- Oh, uh-... O-Oh my-" Samantha's eyes go wide as her gaze lands firmly on Adrian's oversized genitals.

"Yeah, sure 'ave," Adrian kicks his pants the rest of the way off and stands up, letting his shaft swing up at full mast out in the open. Lust has overtaken any notion of subtlety, not that he was doing spectacularly on that front. "Lemme just giv'er backt'ya~"

The mouse pounces on her, quickly bringing her to the floor. He doesn't hesitate with any foreplay or further teasing, entirely unrestrained. He forces his battering ram cock inside of her as soon as he has a grip on the unfortunate girl's body.

PLAP PLAP PLAP SLRRRSH GLRRRPH

Samantha screams as she feels Adrian's three-foot monster ravage her body. Just the tip is already tearing her pussy open just to fit inside, and with only the first thrust when she's brought to the ground, he forces far more than just the tip inside.

PLAP PLAP PLAP SLOSH CHURRRNNN

The swinging of Adrian's balls as he slams into Samantha creates a tidal force inside of them that ravages her equally unfortunate girlfriend. Kayla's body rapidly loses cohesion as she's tossed around inside, waves of cum crashing over head again and again.

"Lesbos like you always 'ave the tightest cunts. Almos' loikya dun' stretch 'em out much~" the mouse taunts as he slams into her again and again. The helpless victim can feel her insides being torn apart by the giant shaft.

The rest of the class, meanwhile, is in shock, some panicking, some picking up their phones to call 911, some just staring in disbelief. The teacher, however, looks more disappointed and irritated than distressed.

"Sit down," Mrs. Sibeil says, "Ignore them." She's had plenty of her own life experience, and she knows a hornet's nest not to poke when she sees one. Judging by how hard Adrian is raping her, it'll be up to fate if she survives no matter what they try to do. Best to not interfere and grab his attention when he's occupying himself with a victim already.

"But, Mrs. Sibeil-" a terrified girl begins to protest.

"None of it. I can and will send you to the office if you don't sit down and pay attention. You don't want that boy's attention anyway," the cougar responds, "There's a video you'll be watching today that will be lecture enough for this chapter. I'll turn the volume up so you can hear it over Samantha being torn open."

"HELP- DEAR GOD HELP ME- I THINK MY UTERUS IS IN MY CHEST-" the otter shouts with as much of her lungs as are still functional.

The class reluctantly and uncomfortably avert their collective gazes. The teacher looks over at Adrian, "And Adrian, silence her, if you could. The rest of us are trying to learn."

The mouse lets out a deep, horrifying chuckle and stares down into Samantha's horrified eyes. 

RIIIIIP

He reaches into her mouth and wraps his fingers around her tongue. With a horrible tearing sound, he rips it out, giving himself a small spray of blood along with it. He stuffs it into the back of her throat, and Samantha's screams and pleas are reduced to a horrible gurgling as all her efforts move to not choking to death on her own tongue and the blood pooling in her maw.

PLAP PLAP PLAP

The mouse pays no attention to the video, and frankly few others do, either. "Your girlfriend's nottin' but cum now. Nice an' mulched up~ Hope you're excited ta gettir back~" Kayla is long gone.

Of everyone in the room, Samantha is certainly the one paying the least attention to the video explaining the reproductive process, but a particular few sentences make her eyes widen.

"The male ejaculates inside the female. This allows the male to inject his sperm, fertilizing the female's eggs. Fertilization is the first step in the reproductive process; from here the entire baby will form," the monotone voice coming from the screen says.

"Mms at gmm appmm t' mmm?" her struggles to breathe pause for long enough to try to choke out a question, not that most of the class can even hear it. One person picks up on it, though.

"Y'hear that? She's askin' ifat's goinna happenta her~!" Adrian repeats her question more audibly, "Canya believe 'er? Bless 'er little heart~"

Mrs. Sibeil looks over at the crime scene in the making on the floor of her class room. There's a look almost like pity behind her apathetic stare. "On the off chance that you survive and your reproductive organs aren't rendered entirely destroyed, yes."

The teacher's response further arouses and invigorates Adrian, as does the terror it brings to Samantha's teary eyes. He begins to ram harder and harder, faster and faster inside of her. The innocent otter is given the feeling of a particularly tough piece of meat that someone is trying their hardest to make into a kebab.

PLAP PLAP PLAP PLAP SPLRRLRFRT

The raw force unleashed inside of Samantha allows her to finally spit up her severed tongue and cough up the blood that was pooling in her maw. A slue of the mouse's cum follows the crimson fluid out. The thought of what parts of her must've been entirely demolished to allow this to happen terrifies her.

Adrian pulls his shaft out of Samantha's body. The enormous cock had crushed many of her organs against her more distal tissues, but when it's removed, they're all unsettled again, hanging limply inside her partially hollowed body.

The otter begins to twitch on the floor, her eyes rolling back in her head. Adrian slaps his bloodied cock on top of her and watches her uncontrollably flail with a sadistic grin. "Howsyer girlfriend taste spittin' er up? Oh roight~ You don't 'avva tongue, now do ya? Guess you're lacking plenty of yer guts after what I didt'ya. Feels nice watchin'ya twitch~"

A few hands go up toward the back of the class.

"Yes?" the teacher addresses them.

"Can we, uhm, go to the bathroom?" one girl asks.

"It's, like, an emergency," another adds.

"For all of us, yeah," says a third.

Mrs. Sibeil rolls her eyes. They could hardly be less subtle about wanting to skip class, but for once she really can't much blame them. Adrian is still rubbing his cock against and salivating over a ravaged girl who's only distinguishable from a corpse by her violent twitching. "Yes, you may, but you'll have to read the reproductive chapter from your textbooks if you're missing the video. Or don't. There's not going to be a test for this either way."

Adrian is brought to attention by a sound he did not expect. The door handle turns, and it slides open. He passes a glance toward the teacher who is glancing over at him in turn. She must've caught on to what he was trying to do.

The video meanwhile progresses through the stages of pregnancy. When it reaches a section on the late stages of pregnancy, a student asks Mrs. Sibeil an innocent question. "Are you that far along, Mrs. Sibeil?"

The teacher stifles a sigh and answers the question, preferring not to show weakness by hesitating. "Yes. The baby is due quite soon."

As if Adrian's raging desire to rape and kill the cougar weren't intense enough before, hearing this makes his need to demolish her reach a critical mass.

Adrian watches Mrs. Sibeil's cold, apathetic stare turn to an expression of dread then panic as he approaches and she realizes what she's in for. It's a delicious sight. She gets up from her seat and attempts to move for the door, but the mouse is upon her before she can get out from behind her desk.

He pushes her over onto it and clambers onto her. With his short stature he does need to climb up her a little to reach her snatch.

"Adrian, you menace- Get off-" Mrs. Sibeil's protests are cut off by an agonized yelp forced out of her by Adrian forcing his cock inside of her.

PLAP PLAP PLAP

"Oh I'll be gettin' off alroight~" he says with a sadistic twinge to his voice. On the first thrust he can already feel the shape of her unborn over his cock. The infant's small, developing limbs sprawling out in four directions over the head of his cock, its soft body pressed between the tip of his shaft and the wall of the teacher's womb, it's a feeling he can't get enough of.

PLAP PLAP PLAP CRUNCH

While he's starting to consolidate all of her organs inside of her chest cavity, in the first few seconds of his brutal rape, Adrian feels something break with a sickening crunch. Light spasms of tiny limbs over his tip inform him that Mrs. Sibeil's would-be child isn't dead yet, though. This brings a smile to Adrian's face. He hopes it's developed enough to feel pain.

PLAP PLAP PLAP

Mrs. Sibeil wretches and vomits blood and viscera onto the floor in front of her desk. The stunned students are all lined up as the perfect audience for Adrian's fun. One girl in the front even feels some of it splatter onto her. She joins Mrs. Sibeil and many of her classmates in a growing choir of screams.

PLAP PLAP PLAP

Adrian looks up at the remaining students with the same hungry look he would give a buffet. The cougar will not be his last victim today. Not even his last victim this hour.

Mrs. Sibeil leaks tears from her eyes, her body too ravaged for her to expend the energy to properly weep. Her screams have turned to gurgling noises as she continually spits up her own blood. Inside her body, her own unborn is being rammed through the tangle of her intestines into her lungs. 

She and Adrian can both feel it being torn apart from the violent rape. Its chubby, developing body splits nearly in two in the middle where the brunt of the force is going. The mouse's cock forces the unborn's tiny spaghetti guts out through its torn open back. Tiny, shattered vertebrae lodge themselves in Mrs. Sibeil's vital organs.

PLAP PLAP PLAP

There's been a silent debate among the girls remaining in the room on if they should flee and draw attention to themselves or stay and hope he doesn't come for them next. A small handful more have left already, but many remain glued to their seats.

"Birth is the process by which the fully formed infant exits the womb. Though it is a painful process that requires special attention and care, it is the child's introduction to the world, and there is beauty in that. Birth is the miracle of life." The narrator of the video speaks in the background, a bit more philosophically than throughout most of the prior sections; it's not uncommon for schools to have such undertones in their learning material.

SPLRRRPRT SPLATTLRRTLT

The mouse has finally collapsed the teacher's lungs with her child ornamenting his battering ram when he climaxes. The cougar doesn't get the chance to asphyxiate.

High-pressure cum forces dismembered infant parts upward past Mrs. Sibeil's thoracic cavity and through her neck. The cougar's cranium explodes open as they impact the top of her skull along with the mouse's load. Brutalized pieces of the recently deceased teacher's bundle of joy rain down on the class in a spray of Adrian's cum and Mrs. Sibeil's viscera and grey matter.

Nobody remains seated following the shower. One girl has a tiny hand land open-palmed on her face. Another finds the dead, glazed over eyes of a feline infant staring up at her from her desk. It's more than enough to send them toward the door.

It's a chaotic stampede as the girls all run for the exit. Screams overwhelm all other sound, and girls injure each other through sheer force as they try to shove through the tiny doorway. Meanwhile, Adrian watches it like his own personal show to enjoy while taking in the afterglow of his fresh double kill and slowly working his cock out of the teacher's still-warm corpse.

When he finally gets up, the last of the girls are filtering out into the hall. He catches the last two by their collars. Their screams turned to terrified babbling and sobs as they're dragged away from the door.

His next victims are a falcon and a cat. Adrian throws the cat to the floor and slams his ass down onto her face. He pulls the other girl to the ground and lays his blood-soaked cock on top of her. "Really lookin' forward to eatin' and snuffin' allo those girls who ran away. Roight buffet they're goinna be~" he says as the girls attempt to struggle free, "Oh, an' oi guess you two oughtta make fer an appetizer at least."

SCHLRK

He rubs his ass on the girl whose face he's seated on, and her muzzle slips inside, followed shortly by the rest of her head. She finds her face steadily covered in more shit the deeper he pulls her in as any residual amount of it lining his colon is picked up by her head scraping all sides of it at once. Adrian begins to scoot forward a little at a time to pull her deeper.

Simultaneously, he takes the falcon and puts her head up against the tip of his cock. He can't quite reach her head with his hands due to his own length, but with a little doing he manages to use his tip to force her beak open. No girl's mouth can open wide enough to handle his giant shaft, but an avian with a solid beak like hers is going to have an even worse time with it.

CRACK

He instantly pries her beak open wider than it should go, and moments later has successfully, violently separated its upper and lower portions. He stretches out her face grotesquely as he forces his shaft inside.

SQULCH SGLRRFK

The cat meanwhile, is halfway inside of Adrian's body being bowel baked into mouse manure. Though she hasn't had her lower half stuffed in yet, her face is already burning as her flesh is rendered into shit. The falcon can feel very firmly inside of her every throb of Adrian's cock spurred on by the mouse's pulses of increased arousal at the cat's desperate struggles against his prostate.

Adrian forces his cock deeper into the avian's body, finally able to reach her head now that it's impaled on his shaft, though it's a bit tricky with his gut full of half a cat in the way. He tugs her further onto it. The flesh of her throat is warped and begins to tear as the mouse's size pushes it well beyond its limits.

His bitch breaker does its job easily enough when rammed through a girl from the bottom, but when entering through her mouth, its time to kill is reduced even further. By the time Adrian has started pulverizing all the organs in her chest, she's already in her death throes.

GLRRGGLGFFF SCHGLRRK

The cat meanwhile has grown still, the flesh around her head dissolved into filth and her brain replaced with mouse shit. Her lower body is working its way inside of Adrian now; currently, her hips are being worked into his ass.

Adrian continues to indulge himself and desecrate the girls' remains, working his cock into the falcon and continuing to tear her apart into a shape resembling a fleshlight while the rest of the cat disappears into him.

PLAT PLP SPLRRFT SPLATLRLRTRTRT

After a while, his shaft all the way inside the falcon and the entirety of the cat's body pressing on his prostate, he has his third orgasm of the hour. The falcon's intestines are forced out of her cloaca in a tangled, pulped mass, along with bits of tissue too damaged to tell what organ they were a part of. A long spray of blood and cum lands on the ground behind the dead bird of prey.

When Adrian pulls her off his cock, her head has been entirely separated from her body due to her throat being shredded by his girth, and he has to take a moment to push it off of him as well. With the cat inside of him fully digested and the bell about to ring, he makes his way over to Mrs. Sibeil's corpse to finish off the hour.

The mouse finds the largest patch of the cougar's fur he can that hasn't been soaked in bodily fluids and wipes his cock clean on it before pushing the teacher's corpse off the desk and leaving it slumped against the side. He then climbs onto the desktop and hangs his ass over the edge. "Think you'll make a betta latrine than a mother, teach~" the mouse says as he grips the sides of her head with both hands to hold it in place.

FBLRBFLRRRLT BRLRFPRT SPLRRLTT

A hundred pounds of shittified cat pours out of Adrian's ass and into the gaping hole in the teacher's skull. Her corpse bloats out with the mess of scat and bones to a size similar to that which she had before half of her innards were blasted out of her along with the remains of her child. The mass of the shit dumped in more or less equates to that of the organs blown out.

BRBLRTRT SPLRTFT

When the last of the cat's remains have been vacated of Adrian's bowels, he gets up off the desk and reaches for Mrs. Sibeil's family photos. She has a dozen of them framed on her desk, quite a beautiful family of at least six distinct people he can count in them.

They make for suitable enough toilet paper for the mouse who pulls them each out of their frame, wipes with them, and tosses them away. He even has one left over of a younger Mrs. Sibeil holding her first child. With nothing better to do with it, he tosses it into the teacher's open, shit-filled head, collects his pants, and makes for the door.

The bell rings to signal the end of the hour, and all the girls who hadn't been driven from their classes by a murderous mouse join Adrian in the halls, keeping their distance as usual.

"Lunch up next," he comments to himself, "and 'bout time, too. I'm starvin' ova here."
