The Beasts seizes them both...

“TITS! Want TITS! Want Cunts!”

Before either of them could move the Beast seized its monumental Beasthood in one massive paw and shot a thick ropy burst of pre-cum at them. It looped through the air like a mortal round before splattering across their upturned pretty faces, slender necks and acres of exposed cleavage. The immediate effect it had on the two barely legal beauties was electrifying.

"Wha- Oooh~ fuck!"

Sonya fell to her knees gasping as a dense line of sticky seed dripped from her temples to her chin and a bolt of ecstasy ran through her. Not the narcotic bliss she had usually felt in the past but an almost painful roaring pleasure that ran roughshod through every muscle in her body.

Beside her Bianca dropped to her knees and Sonya could make out the busty goths body spasming and swelling as she felt her own doing the same.

The pale white flesh of Bianca’s already sizable breasts was expanding and the laces that held the corset closed began to fray then snap under the building stress. Her slender hips spread as if to accommodate a litter of young and her slim thighs broadened with firm muscle, laddering her fishnets and causing the zip on the side of the leather skirt to burst.

Sonya could feel the same happening to herself and gasped with relief as the tightening cheerleader's outfit finally tore apart under the strain of her rapidly swelling mounds. It has been getting difficult to breathe…

“Pussy… want fuck…” growled the monster in its broken language causing Sonya to look up in both surprise and no small amount of shock. Surely it couldn’t still be erect after shooting that mega-load!

"You want pussy?" She panted, grabbing her obscenely over-stuffed breasts and thrusting them up towards him. "C'mon big boy. Come ruin my little cheerleader pussy with that giant fuck-stick of yours!"

Almost in response the Beast that was once Dr Turner knelt over her and tore off the tattered remains of the uniform. It exposed her wet aching pussy then unceremoniously grabbed its girthy shaft in a meaty fist then slid the angry head of its colossal cock into her soaked cunt.

"Ooohmaagaawf~ yes!"

Sonya gaped as she felt her channel stretch to take it all in, and then moaned as it pushed even more of its immense length into her warm slick depths.

Beside her Bianca had freed herself of the remains of her own ruined clothing and pulled her super-stacked self up beside the bulging muscular form of the Beast.

"Don't forget about me, Mister. You said you wanted tits? Mine are some of the biggest in the school!"

Its beady eyes took her in at a glance then it wrapped an arm the size of a young tree trunk about her hourglass waist and lifted her immense dripping melons to its face. Bianca squealed in delight as it latched its thick lips hungrily about an engorged nipple and began feeding ravenously.

“Oh Fuck!” Bianca cried as she trembled with an immediate and wracking breast-gasm “Not so rough… Oh fuck!”

Sonya was not about to be ignored though, breathing in heavy panting breaths the beautiful blonde cheerleader bucked her bubbly ass downward forcing another pussy-stretching inch of the monster's throbbing tool inside her.

The Beast growled around its mouthful of milky tit-flesh and grabbing Sonya’s maturing hips with its one free hand, sank its full length into her snug spasming cunt . Sonya cried out in both pain and ecstasy as she felt herself stretched to her limits;

“Oh God! Too big… Oh God… please… fuck me, Fuck Me, FUCK ME!!”

She was almost babbling as The Beast moved its arm from her waist, reached behind her back and lifted her as it sat back into a kneeling position. Then it dragged Sonya down onto its lap, impaling her on its massive manmeat in a single brutal thrust.

"Aaaayyeeeess~!"

She wailed and thrashed, cumming ecstatically as the creature still held Bianca held up in one arm, her curling toes suspended off of the ground as it hungrily fed on her massive milk-laden melons. The two cock-hungry XXX-sluts were helpless as dolls against the size and strength of the creature.

With a bestial grunt it began to roll its hips forward and back, sawing its length in and out of the bodacious young blonde. Began slowly but like a growing avalanche it gathered speed and momentum.

"Ooohnnff~ f-fuck… so big… mmmnph~ g-gonna split me w-wide open…"

Sonya stuttered as she felt her contorted pussy squeeze convulsively about the monster-meat inside of her. Stars danced behind her eyes and she began to meet The Beasts movements with her own **** hip thrusts down onto its cock, drawing its magnitude in deep. Her little fists hammered uselessly at its burly chest as her body screamed with pleasure, her long muscular legs locked as far around its trunk of a waist as they could reach, digging her heels into its back and pulling herself into each of the creature's rampant penetrations.

“ple… please.. slow down… I, I, I… can’t bare it anymo…” Bianca pleaded somewhere beside Sonya but the bucking blonde barely heard the stacked raven-haired stunner as she rode the Beast with lip-biting intensity.

Sonya braced her out-flung hands against the monster's immense shoulders, looking down past her hefty heaving tits at her pussy and watched the creature's hugely engorged cock stretch her lower lips as it pistoned in and out of her furiously. Her platinum blonde hair clung to her golden sweat-slick skin as she rolled her hips and ground her crotch into the Beast's lap.

"Yes, fuck me! Yes yesyesyesyes~!"

There wasn’t any pain anymore, her transformation was done and she took the creature’s rampaging immensity inside her new self eagerly, her enormous breasts bouncing heavily and gleeful giggles escaping her lips.

The Beast was still ravaging Bianca’s full fleshy orbs as it came without warning, blasting its torrential load into Sonya’s waiting womb.

"Oh faaaark~! Mmmhmmm, give it all to meeee~!"

Sonya cried out as the wave of euphoria followed slammed into her with all the **** of a freight train and every one of her powerful new muscles seized in a paroxysm of carnal gratification. Every cell in her body seemed to sing with it and as she passed into blissful darkness her head lolled to one side and she saw Bianca…

The huge titted young goth had gone limp in the creature's iron grip and a line of spittle fell from her chin to land in her billowing cleavage as the monster sent her through breast-gasm after crashing breast-gasm with its endless rough feeding on her overstimulated nipples.

Bianca looked like an entirely different woman… her newly swollen breasts sat high and impossibly full, her waist was still waspish but her sleek young hips had thickened as had her ass, more rounded and packed with muscle. Her thighs were thicker too but her limbs remained long and the new lines of her body screamed of a ripening fertility and promiscuous promise.

Sonya wondered how she must have looked as she too had felt the changes come upon her. Right after that first burst of cum had hit her and blasted her into sweet oblivion…
