Professor Jake walked to the lectern. “Settle down, ” his voice boomed through the microphone, silencing the crowd. “Today’s special guest lecture is on practical, applied anatomy. Our subject is Lily, who has so graciously volunteered her body for our educational benefit.”
A wave of excited whispers rolled through the auditorium. All eyes were locked on Lily, who stood frozen at the foot of the stage steps.
“Lily. The stage. Now. And strip, ” Jake commanded, his voice leaving no room for argument.
The shy part of Lily wanted to die. The slutty part was dripping. With clumsy fingers, right there in front of hundreds, she repeated the process from the office. Sweater off. Jeans and panties down. She stood naked under the harsh stage lights, her beautiful body completely exposed. A collective gasp and then hungry murmurs filled the air. Whistles and crude comments flew from the crowd.
“Look at those udders!”
“Fuck, that ass is insane!”
“I always knew she was a bitсh in heat!”
Lily’s skin burned, but her nipples were diamond hard, and her cunt was a soaked mess.
“Walk to the center of the stage, ” Jake said. Lily did, her full tits bouncing with each step, her ass cheeks clenching and releasing. The projector screen behind her flickered to life, showing a high-definition close-up of one of her heavy breasts from the office photos.
Jake picked up a long, thin wooden pointer stick from the lectern. He approached Lily, who trembled. Without warning, Jake swung the stick through the air.
THWACK!
It landed squarely on the underside of Lily’s right breast, making the fat flesh jiggle violently. Lily cried out, a sharp sound that morphed into a moan.
“Observe, ” Jake said into the microphone, his voice clinical yet dripping with perversion. The screen changed to a side view of Lily’s tit. “The subject exhibits pronounced mammary hyperplasia. These are not just breasts; they are fat udders, designed for display and for milk production.” He groped Lily’s assaulted breast roughly, squeezing the softness, making it spill from his fingers. THWACK! He hit the other one. Lily moaned again, her back arching.
“Note the elasticity, ” Jake continued, slapping one tit after the other in a rhythm, making them bounce and sway obscenely. Lily’s moans became a constant soundtrack. “When this slut is pregnant, and a hole this greedy will inevitably be bred, these udders will swell further, veins will become prominent, and they will leak milk at the slightest stimulation.” He punctuated his sentence with a particularly hard slap to Lily’s left nipple. Lily screamed, her knees buckling slightly.
“Penetration of the nipples is possible, ” Jake lectured, grabbing a handful of Lily’s tit and shaking it. The image on screen zoomed in on her nipple. “The nipple duct can be forced open with sufficient pressure, allowing for deep tit-fucking or for the injection of semen directly into the milk glands. A useful way to mark breeding property.”
The crowd roared with approval and lewd shouts. Lily was panting, tears of shame and pleasure in her eyes, her tits throbbing and red from the beating.
“Enough of the upper anatomy, ” Jake said dismissively. He pointed to the wooden chair. “On the chair. On your back. Legs over the armrests. Spread yourself for the class.”
Whimpering, Lily obeyed. She sat on the chair, then leaned back, hooking her legs over the wooden arms. It spread her thighs impossibly wide, lifting her hips and putting her sopping wet pussy on brutal display for the entire auditorium. The screen changed to a close-up of her spread cunt from the office photos.
“Now we examine the primary sexual organ, ” Jake announced. The crowd leaned forward.
“Look at it glisten!” someone yelled.
“It’s begging for a dick!”
“Fucking wreck it, Professor!”
Jake tapped Lily’s swollen clit with the tip of the pointer stick. Lily jerked and mewled. THWACK! He brought the stick down hard on her clit. Lily shrieked, her body bowing off the chair.
“The clitoris is the center of pleasure for this kind of flesh, ” Jake explained, rubbing the stick cruelly over the nub. “But its real purpose is to make the bitсh wet and ready for penetration, no matter how rough or unwanted.” The screen showed the zoomed-in image of Lily’s glistening folds.
He then put down the stick and picked up a clear plastic ruler from the lectern. “We will now measure the vaginal depth.” He pressed the cold ruler against Lily’s soaked entrance. “Relax, whore. This is for science.”
Lily sobbed, but she was too far gone to resist. Jake pushed the ruler into her tight, wet channel. It slid in easily thanks to her arousal. Lily’s moans filled the microphone as the ruler invaded her, inch by inch, until it met resistance deep inside.
Jake pulled it out and showed it to the camera. The screen displayed the ruler, slick with Lily’s juices up to a certain point. “Seven inches, ” he declared. “A shallow but serviceable hole.”
A male student near the front shouted out a question, his voice thick with excitement. “Professor! What happens if a cock bigger than seven inches rapes her?”
The question sent a violent thrill through Lily. She moaned loudly, her pussy clenching around nothing.
Jake smirked at the student. “An excellent question. For rapemeat like this, no cock is too big.” He tossed the ruler aside and picked up a cold, steel speculum from a tray. The crowd oohed.
“A large cock will simply force its way deeper.” He coated the speculum in lubricant from a bottle, though Lily was wet enough. “It will hammer against the cervical hole, the entrance to the womb, and eventually, with enough force and the bitсh’s willingness to be broken, it will force it open.”
He brought the instrument to Lily’s spread pussy. “Now, we visualize the cervix.” He pushed the speculum inside Lily’s stretched hole. Lily cried out at the cold, invasive feeling of being pried open. With a few twists, Jake opened the speculum’s jaws, spreading Lily’s inner walls wide apart.
A small camera was attached to the speculum. On the giant screen, a live feed appeared: the pink, mushy walls of Lily’s vagina, leading to a small, tight dimple at the end, her cervix.
“Observe the virgin womb entrance, ” Jake said, his voice husky with fascination. “The hymen is irrelevant; it’s a trivial membrane. The real prize is this.” He used a thin probe attached to the speculum to tap the cervical hole. Lily jolted, a new, deeper kind of sensation shooting through her. “This is the gatekeeper. When this is penetrated, the slut is truly claimed. The womb is flooded, eggs are coated in seed, and breeding is guaranteed.”
He put down the probe and picked up a long, clear test tube, about half an inch in diameter. He smeared it with lube.
“We will now measure the uterine depth.”
Lily’s eyes went wide. “N-no... please... not there...” she begged, but her body was shaking with need.
“Silence, ” Jake hissed. He guided the tip of the test tube through the speculum, right up to the tiny opening of Lily’s cervix on the screen. He pressed.
Lily screamed. It was a blinding, white-hot pain mixed with shocking pleasure. The tube was forcing its way through a ring of muscle never meant to be entered. Jake twisted it slowly, applying relentless pressure. On screen, the class watched as the tip of the tube began to disappear into the tiny hole, stretching it obscenely open.
With a final, wet pop, it slid inside Lily’s cervix. Lily let out a broken wail, her body seizing. Clear fluid, not piss, gushed from her urethra, soaking her ass and the chair beneath her. She’d squirted from the cervical invasion.
Jake pushed the tube further, inch by agonizing inch, into Lily’s womb. Lily trembled and writhed, but ropes that had been hidden on the chair were quickly fastened around her ankles and wrists, holding her down in the spread-eagle position. She was trapped, impaled on display.
The test tube went in nearly to its full length before meeting the far wall of her womb. Jake pulled it out slightly and checked markings on its side.
“Uterine depth is approximately six inches, ” he announced to the rapt audience.
Another student yelled out, voice trembling with lust, “What if... what if a dick is bigger than thirteen inches total, Professor? What then?”
Jake looked at the student, then down at Lily’s ruined, trembling body bound to the chair. His smirk was devilish. He leaned into the microphone, his eyes locked on Lily’s tear-streaked face.
“An even better question, ” he purred. “That will be the practical demonstration... after this presentation is concluded.”
He pushed the test tube back to be buried deep in Lily’s womb, the end of it protruding from her violated pussy, and walked back to the lectern as Lily sobbed and shuddered on stage. A hush fell over the auditorium, broken only by Lily’s wet, ragged sobs and the low hum of the projector.
“The anterior anatomy has been catalogued, ” Jake announced, his voice slicing through the heavy air. “Now, we examine the posterior. The true utility hole.”
He moved behind the chair where Lily was tied. With quick, practiced motions, he unfastened the ropes from Lily’s ankles and wrists. Lily slumped, boneless and trembling. “On your hands and knees, whore. Present that celebrated ass for the class.”
Whimpering, Lily obeyed. She pushed herself off the chair, the test tube shifting inside her with a sickening sensation. She got on all fours on the hard stage floor, her head hanging low. This position lifted her fat, round ass high in the air, the cheeks perfectly parted to reveal her tight, pink pucker, winking nervously just above her slick, used cunt.
The screen changed to a high-definition image of Lily’s asshole from the office photos, zoomed in until every wrinkle was visible.
“Observe the anal sphincter, ” Jake began, tapping the hole with the tip of his pointer stick. Lily flinched. “Unlike the vaginal canal, this is a true tunnel. No cervix, no womb to block the path. Just endless, hot, tight gut waiting to be stuffed.”
He pressed the stick harder, and the tip began to sink into the tight ring. Lily gasped, her back arching. “It’s a cocksleeve with no end. A dumpster for any seed or waste a man wants to leave in his property.”
He worked the stick in an inch, then two, twisting it. Lily moaned, a broken sound. “With proper training and enough force, this hole can accommodate objects far beyond the limits of the front cunt.”
A bold male student near the front, his face flushed with excitement, shouted out. “Bullshit, Professor! That tiny rosebud? It can’t take anything huge!”
Jake slowly pulled the stick out of Lily’s ass, making her whine at the loss. A cruel smile played on the professor’s lips. “A challenge? Excellent.” He looked at an assistant lingering in the wings. “Bring out Subject Delta.”
The assistant wheeled out a cart. On it lay a monstrous silicone dildo. It was a terrifying thing. Twenty inches long. It tapered to a point at the tip, but the base flared out to a brutal five-inch diameter. It was a glossy black, and along its length were clear numeric markings, 1, 2, 3, all the way to 20. A collective, hungry gasp rose from the audience.
Lily’s eyes went wide with genuine terror. She shook her head frantically. “N-no... no, Professor, please... I can’t... that’s too big... it’ll rip me...”
“Your opinion is irrelevant, rapemeat, ” Jake said coldly. He took a large bottle of thick lubricant and squeezed a generous amount over the terrifying toy, coating it until it shone under the lights. More lube was poured directly onto Lily’s trembling asshole, dripping down her perineum.
