Hannah Thompson tore open the sachet and emptied the white powder into her glass. Immediately she caught a whiff of something unpleasant and she recoiled involuntarily.

"Are you sure I can't offer you anything?" asked her friend Destiny Rapana, munching on a chocolate doughnut.

Hannah shook her head. It was typical of Destiny to try to tempt her with sugary treats just when she was about to start another diet. And it was typical of Hannah to firmly resist.

"You know you're not actually fat, right?" continued Destiny cheerily. "So what if your bum looks a little big in that dress? You normally look fine. Just don't wear stuff that's so clingy…"

"Great. Thanks for that," replied Hannah sarcastically, giving her friend a mildly annoyed look.

"Sorry," said Destiny, trying to look contrite while sucking icing off her thumb. "You know, I think it's really cool how you have so much willpower. I couldn't do it. So what's that stuff again?"

"It's a new meal-replacement shake. You can't get it here yet. I imported it from Japan," replied Hannah. "Someone linked it on Facebook."

"What's so great about it?"

"It makes you feel full, but it's got negative calories," said Hannah.

"Negative calories?" asked Destiny incredulously.

"Yeah. You're supposed to lose weight just by drinking it." Hannah felt dumber just for saying the words.

"You know that's impossible, right?" asked Destiny, using a tone of voice usually reserved for placating dangerous mental patients.

"Doesn't hurt to try." Hannah got up from Destiny's kitchen table and went over to the sink. "I think you're supposed to mix it with warm water."

Destiny picked up the packet and regarded it suspiciously. "Are you sure? This is all in Japanese."

The mixture smelt even worse with water added. Hannah stirred it with a spoon, her nose crinkled with revulsion. The thick, white concoction had the texture of mucus.

"I can't believe you're going to drink that," said Destiny, admiring her friend's dedication.

Hannah was having serious doubts herself, but she didn't want to look stupid in front of Destiny. "Bottoms up!"

She downed half the mixture in one gulp, then promptly wished she hadn't. It felt stringy and globby in her mouth, like partially-blended oysters, and the smell was truly rank. Once, twice, three times she retched, but she managed to keep it down.

"Are you okay?" asked Destiny, a concerned look on her pretty features.

"I feel violated!" choked Hannah, tears running down her face.

"So what's it taste like?" laughed Destiny.

"It's a bit salty. Do you want some?" asked Hannah, proffering the half-full glass.

Destiny demurred. "I think I'll pass. Is it working yet?"

"Well, I definitely don't feel hungry now," replied Hannah with a laugh. She tipped the rest down the sink, watching in revulsion as it slowly oozed down the plug hole. She wondered what she was going to do with the ten remaining boxes of the stuff.

"Hey, guess what?" chirped Destiny. "I went shopping this morning. Wanna come and see what I got?"

"Sure!" replied Hannah, following Destiny to her bedroom.

Hannah Thompson sat on the bed and watched while her friend Destiny Rapana modeled the proceeds of her latest shopping trip. On those occasions when they hadn't gone shopping together, these get-togethers were an opportunity to get trusted feedback about their purchases, and also show-off a little.

"That one's nice," said Hannah as Destiny spun around in a cute floral summer dress. But secretly she thought it would look better on herself.

Destiny checked herself out in the mirror. "Pretty darn cute if I say so myself!" she said chirpily, before pulling the dress up over her head and tossing it over a chair. She bent down and began rummaging around in her shopping bags for the next item. Hannah averted her eyes from the rather lewd display of Destiny's rounded arse clad in pretty silk panties and looked out the window. It was a nice day outside.

Destiny finally pulled a navy blue swimsuit out of her bag and held it up for inspection.

"Good colour choice," said Hannah.

"Yeah, I don't want a repeat of last time," giggled Destiny. Her previous swimsuit had been white and she'd only worn it once, due to it becoming completely transparent when wet. "I still haven't dared go back to that swimming pool."

"Is it hot in here?" asked Hannah, suddenly noticing that she was starting to feel flushed.

"No. Do you want the window open?"

"I'll be fine," replied Hannah. She hadn't been feeling quite right since downing the vile concoction in the kitchen, but she wasn't feeling sick exactly — just vaguely light-headed.

Destiny reached back to unclip her bra, then shrugged it off her big boobs before tugging her panties down and kicking them away. Hannah watched idly. She'd seen her friend naked many times before.

Suddenly she began to feel dizzy. A sensation like a thousand nervous butterflies spread quickly from the pit of her stomach, making her heart flutter. She put her hand on the mattress to steady herself. Something was seriously wrong. "Destiny…" she gasped, but her mouth was dry and her call for help was barely a whisper.

Destiny tugged the navy one-piece up her thighs, oblivious to her friend's distress. It was a tight fit. She adjusted the gusset between her legs, then yanked it tight so she could get her arms through the shoulder straps.

Hannah felt a strange tingling heat start to burn between her own legs and her heart rate seemed to increase with each beat as an inexplicable flush of arousal engulfed her. She clamped her legs together but this made things worse. "Destiny…" she panted.

"Yeah?" Destiny, now squeezed into a swimsuit that was at least a size too small, finally looked back at Hannah. "What's up? You look hot."

Hannah started fanning herself. "I don't know. I'm burning up all of a sudden."

"I'll get you a drink of water." Destiny trotted out to the kitchen, her swimsuit riding up her bum as she left.

As soon as Destiny was out of sight, Hannah slid a hand up her skirt and felt between her legs. She found her panties were soaking wet and her clitoris was harder and more sensitive than it had ever been in her life. Just brushing it through her underwear caused her to orgasm strongly. But that didn't give her any relief — it just made things worse.

By the time Destiny returned, Hannah Thompson was almost driven crazy with arousal and embarrassment. She gulped down the water and hoped Destiny didn't notice the way her stiff nipples were poking through her top like bullets.

"I don't understand it," said Destiny obliviously, looking at herself in the mirror and tugging the material out of her pussy cleft, where it insisted on forming a highly invasive cameltoe. "I'm sure this thing fit in the shop. Oh well."

Hannah didn't reply, being more concerned with what was happening to her own pussy, and her clitoris in particular. It was like it was getting bigger and harder by the second. Even more disturbing was how her feelings were changing towards her friend. Unable to keep her eyes off Destiny she felt a sudden urge to throw her on the bed and kiss her. With this image in her mind, her pussy literally drizzled a flood of girl-juice into her panties and her clitoris bulged dramatically.

Destiny Rapana extricated herself from the swimsuit and pulled a black lace bra and matching panties out of a bag. She pulled the panties on while facing away from Hannah, and so was unaware of her friend's lustful staring. The panties were semi-transparent and a seam ran up the back so that they hugged all the curves of her bottom. Then she wriggled into the bra, which was similarly sheer. Her perky nipples were clearly visible through it.

"What do you think of these? Too sexy?" Destiny asked, performing a little pirouette. Then she saw what her friend was doing and she gasped in shock, her graceful dance-move ending in a clumsy stumble. Hannah had thrown herself back on the bed with her skirt around her waist and her hand was moving very vigorously inside her soaking panties.

"Jesus fucking Christ, Hannah, what the hell are you doing?" Destiny cried.

Hannah Thompson's face was bright red with embarrassment. "Destiny … sorry… something's wrong… can't help it!" she gasped as she convulsed with another orgasm. This in turn caused her arousal to ratchet up another notch. In her delirium she tore off her panties and flung her legs wide.

Destiny stared aghast. "Hannah! Wha… What the hell is that?" she stammered, pointing at her friend's clitoris. It was now as big as a pickle, smooth and slightly curved. Before their wide eyes it swelled and lengthened, until it reached at least ten inches long. Then a bell-end formed and a slit opened up at the tip, from which a thick white fluid started dribbling.

"Is that… is that… a dick?" Destiny whispered.

"What's happening to me?" moaned Hannah in distress, before grabbing her newly-formed cock and jerking it furiously. Destiny stepped backward nervously.

"Um… yeah Hannah, do that. Maybe if you, um, finish off… maybe it will go away…"

Nothing could have stopped Hannah Thompson from doing exactly that. Her fist became a blur as she jacked off her oozing cock. She closed her eyes and found herself visualizing Destiny Rapana's naked body. She imagined her mouth on Destiny's tits, her hands on Destiny's arse… This wasn't how she was supposed to feel about her friend! She opened her eyes to get rid of the visions and was treated to the sight of the real Destiny looking super-hot in her sexy new underwear.

"Oh God, Destiny!" groaned Hannah as a powerful orgasm hit and a highly pressurized fountain of semen exploded out of her cock and showered down all over her. Her skirt and blouse were drenched and salty droplets fell into her gasping mouth. Destiny's bedcovers didn't escape either.

"Holy shit!" shouted Destiny, recoiling but unable to avert her eyes from her twitching, cum-spurting friend. The orgasm lasted about thirty seconds. At the end of it, Hannah's cock showed no sign of deflating. In fact, it looked bigger.

Hannah was now dealing with lustful feelings of an intensity rarely experienced by human females. (There are some monkeys in Borneo that get hornier, but they aren't relevant to this story.) Desperate for relief, she locked eyes with Destiny and suddenly knew what she had to do.

Something in Hannah's gaze made Destiny extremely nervous. It was like the real Hannah had stepped out of the building and a sex-crazed hermaphroditic replica had taken her place.

"Destiny, I'm sorry," said Hannah. She climbed off the bed and dropped her cum-soaked skirt and blouse to the floor. Now she was naked except for a white bra. Her fat cock pointed upward at a sixty-degree angle, steadily dripping sperm on the carpet.

"Um, that's okay. It could have happened to anyone…" said Destiny, edging towards the door.

"No Destiny, you don't understand. I'm afraid I'm going to have to use this thing on you!" said Hannah sadly as she moved to block Destiny's escape route.

"The fuck you are!" cried Destiny, then quickly attempted a sudden dash past Hannah. It didn't work. Hannah grabbed her by the elbow, swung her around and threw her on the bed where she landed with her legs in the air. Hannah leapt on top of her with frightening speed.

"You wanted my opinion? Yes, these are too sexy!" said Hannah. She dug her fingernails into the crotch of Destiny's flimsy panties and proceeded to tear them to shreds.

"They were new!" howled Destiny as Hannah rubbed her dribbling cockhead up and down her friend's unprotected pussy slit.

"I'm so sorry Destiny, I can't help it. I've gotta fuck you! Please try to enjoy it" moaned Hannah, nuzzling her face into Destiny's neck and showering her with kisses.

"Fine, just make it quick," sighed Destiny in resignation. The dick was huge, but it might not be so bad if Hannah was gentle…

Hannah Thompson rammed her enormous, oozing cock into Destiny Rapana's unprepared cunt with a grunt and a wet squelch.

"Aaiiieeeeee!" screamed Destiny. This was without doubt the biggest, fattest thing she'd ever had shoved up her. Her brain was still having difficulty processing what was happening. If someone had told her that morning that her friend was going to suddenly grow a dick and fuck her with it, she would have been extremely skeptical.

Consumed by lust, Hannah pounded Destiny relentlessly. With each wet and gooey thrust, white juice squirted out of Destiny's stretched-out pussy and pooled under her bum cheeks. Hannah marveled at how wonderful Destiny's soft body felt against her own, her perfume so sweet, her hair so soft. She felt she could fuck her friend's tight pussy for days. But Destiny clearly wasn't into it, and Hannah found this off-putting.

For the first few minutes, Destiny gritted her teeth and endured. But with no end in sight, she decided that her best chance was to bring Hannah to another orgasm as quickly as she could, then hopefully the ordeal would be over.

"Oh Hannah," she murmured, running her hands down Hannah's back and gripping her humping arse cheeks. "That's it. I love it. Fuck me Hannah, fuck me harder!"

This was music to Hannah's ears. She kissed Destiny hard in response, then slid her hand up over Destiny's bra and grabbed her big tits roughly. "Take it Destiny, you little slut!"

"Yeah Hannah, I'm your little slut," panted Destiny with feigned enthusiasm. "Fuck me with your big hard dick. Fuck me like a dirty whore." Deciding to go for broke, she reached around and rammed two fingers into Hannah's dripping pussy.

This was all that Hannah Thompson needed. Her next orgasm hit like a tsunami. She tensed up and shoved her cock as deep into Destiny Rapana as it would go. Jerking and twitching, she flooded Destiny's womb with seed, then withdrew until only the head was left inside. Three more squirts completely filled Destiny's vaginal tunnel with white goo, then Hannah plunged deep inside again with an almighty squish. High-pressure cum sprayed out of Destiny's cunt around Hannah's cock, drenching Hannah's tummy and Destiny's inner thighs.

The fog of lust started clearing from Hannah's mind. She rolled off Destiny, her cock pulling out with a wet sucking sound, and lay next to her, panting. To her relief, the giant dick was becoming flaccid. "Destiny, look, it's shrinking," she said.

"That's totally awesome for you," replied Destiny scathingly. Hannah turned to face her, suddenly cognizant of the shocking nature of what she had just done to her friend. Destiny was lying there spread-eagled, cum literally pouring out of her gaping, twitching cunt.

"Destiny, I'm so sorry!" cried Hannah, now completely lucid.

"Don't talk to me," came the icy reply. "This has severely tested our friendship!"

The two friends lay side by side on the bed, catching their breath. Hannah's cock had now completely disappeared, leaving her with a clitoris that, while not quite as small as before, was still within normal proportions. Destiny's pussy gradually closed up and stopped leaking.

"It seems like it's over now" ventured Hannah eventually.

Destiny Rapana cast a disgusted eye over her cum-stained bed covers. Thick puddles of semen were starting to soak through.

"Help me clean this mess up Hannah. And can you unhook my bra? It feels like it's shrinking…"

Hannah Thompson inspected her friend's chest and blinked in disbelief. "Umm, Destiny… I don't think it's the bra that's shrinking…"

Destiny looked down in horror. Before her wide eyes, her already big breasts were visibly swelling up. Her bra was getting uncomfortably tight, unable to contain her expanding bosom. The straps started digging painfully into her shoulders.

"Get it off me!" Destiny shrieked. Hannah fumbled with the catch and the bra practically flew off as Destiny's tits burst out. They were now at least three cup sizes bigger with nipples that were spectacularly big and fat.

"What have you done to me?" howled Destiny. "How am I going to explain these?" By way of illustration, she squeezed her now enormous boobs in Hannah's direction. To their surprise a jet of milk hit Hannah square in the face.

"Oh, this just fucking keeps getting better and better!" sighed Destiny, unable to stop the streams of milk that were now pumping out of her engorged nipples and running down the sides of her breasts.

Hannah wiped the white fluid out of her eyes, then noticed that Destiny's belly was now swelling up too. She couldn't bring herself to say anything. Instead she just gaped.

Destiny noticed soon enough. "What the hell?" Then realization dawned. "Hannah, you've fucking knocked me up!"

"I'll call an ambulance," said Hannah in a panic.

"Ugh… too late!" groaned Destiny as a flood of clear, thick fluid gushed out of her pussy. She laid back on the bed with her legs spread wide and her eyes rolled back as a series of contractions rippled through her birth canal. Each contraction was inexplicably accompanied by an intense orgasm. "This… isn't… too bad!" she panted.

Suddenly two green tentacles shot out of Destiny's cunt and wrapped tightly around her calves just below the knees. The tentacles then contracted, hauling the rest of the creature out of Destiny in the process, until it flopped out wetly between her thighs. It was squid-like, glistening with slime, with numerous tendrils, pseudopods and other appendages flapping around wildly in the air.

Hannah Thompson screamed. This was just like that awful Prometheus movie, only better written.

Destiny Rapana watched frozen in horror as the thing slowly slithered its way up on top of her. An eyeball on a stalk waved in front of her face, inspecting her. Meanwhile two tentacles with gaping mouths at the ends slithered and slobbered around her chest before finally attaching themselves to her engorged, leaking nipples. Then the creature started suckling loudly at her swollen teats with the force of an industrial vacuum cleaner.

"Get it off me!" cried Destiny as the creature milked her furiously. Hannah stepped forward hesitantly. Mustering all her courage she gripped one of the sucking tentacles and tugged. It didn't release its grip — if anything it increased the suction on Destiny's breast.

"Yeow! Let it go! Let it go!" wailed Destiny, and Hannah happily obliged. As Hannah watched helplessly, Destiny's breasts seemed to be shrinking as the milk was pumped out of them. Her belly was now back to normal and her pussy could actually be seen to be tightening back up.

It was concerning, however, that the creature was rapidly increasing in size.

Finally Destiny's milk ran out and the thing's mouths released themselves from her tortured breasts, leaving her with bright red rings around her nipples. Its various appendages had stopped flailing around and it seemed content. In fact, it might actually have fallen asleep. It was hard to tell.

Destiny struggled ineffectually to get out from underneath the creature, but it was now at least ten times bigger and a dead weight on her stomach. Hannah grabbed her friend's hands and helped to pull her free.

The two women hugged each other in relief, their bodies squishing together with a squelch of slime and semen. Both felt remarkably well, considering what they had just been through. Destiny's giant boobs were a little ungainly, but at least they weren't saggy. Their attention quickly turned to the dozing monster on the bed.

"Is that a baby or did the afterbirth come out first?" asked Hannah.

"That's our kid you're talking about!" remonstrated Destiny, feeling maternal for some strange reason.

"Do we keep it as a pet? Or ring the zoo?" asked Hannah.

Destiny ignored her. "The other kids are going to tease it. That's a given."

"Do you think it's dangerous?"

"How could it be? It's just an iddle widdle baby," replied Destiny, obviously under the influence of pregnancy hormones or something.

Hannah shook her head in disbelief and took Destiny by the hand. "Let's get out of here," she said, reaching for the door handle…

The beast on the bed sprang back into life. Two tentacles shot out and grabbed Hannah Thompson around the ankles, causing her to face-plant on the floor. Her fingernails dug into the carpet as she was dragged back towards the creature. Another pair of tentacles wrapped around her thighs, pulling her legs apart as her lower half was raised into the air, leaving only her face, hands and breasts pressed against the floor. Her pussy and arse couldn't have been more exposed and vulnerable.

The creature remained on the bed, having pulled Hannah's bum up level with it. Short, whip-like tendrils flicked wetly across her bottom and pussy leaving little red welts. The eyestalk leaned in to inspect its prey, and the mouth-tentacles from earlier now sprouted penis-like helmets from the ends and loomed ominously.

"What's it doing?" called out Hannah frantically, unable to see behind her.

"Don't worry Hannah," replied Destiny Rapana helpfully. "I think it only wants to fuck you…"

"But I'm its father…" objected Hannah as she felt a thick drizzle of warm fluid run over her crotch and down her arse crack. The beast was lubing her up. How considerate of it.

It quickly became apparent that the creature's secretions contained a powerful aphrodisiac. Hannah felt her clitoris buzz and her pussy juices start to flow again. Against all logic and reason she found herself desperate for the horrible monster to have its way with her.

She didn't have to wait long. The tip of a penis tentacle started wriggling up and down Hannah's pussy slit, working her lips apart as it fumbled for the entrance. Then it gently eased its way inside. It was fat, with a ridged and lumpy surface that felt quite pleasurable as it slowly pumped in and out of her.

Hannah moaned in ecstasy. This really wasn't so bad — the monster wasn't ravaging her, it was making love to her. But then, without warning, the second penis tentacle suddenly dived between her spread bum-cheeks and rammed its way deep into her tight little arsehole.

Eyes bulging and shocked speechless, Hannah could only dangle and quiver as the two invading cocks pumped her pussy and arse with an alternating rhythm. The pace increased tenfold, her nether regions now a blur of pounding monster dicks. Under the onslaught she was pushed away from the bed as the tentacles around her legs began to lose grip. Another tentacle shot out and wrapped around her bra strap in an attempt to stop her escaping. After a few painful seconds her bra broke and her tits burst free. Hannah managed to crawl a short distance away before the tentacles regained purchase and started dragging her back again.

"A little help here…" she suggested.

Destiny leapt into action. "Okay, I know we're its parents and we're supposed to love it unconditionally, but seriously, fuck this thing!" she yelled, reaching under the bed. She pulled out a baseball bat and started raining down a series of brutal blows at the base of the creature's eyestalk. With all major tentacles wrapped around Hannah, the monster was unable to defend itself in time.

After receiving ten good whacks with the bat, the creature started its death-throes. Hannah was jerked around violently in its grip, the tentacles inside her quivering epileptically. Then it collapsed, the bulk of its body deflating with a soft pfft-sound.

"Thanks Destiny," said Hannah, pulling a still-twitching tentacle out of her arse while staggering away from the corpse.

"Not a problem, babe," panted Destiny, grabbing Hannah by the arm and pulling her through the doorway. They slammed the door behind them and collapsed in the hallway.

The two friends slumped side-by-side against the wall. Holding hands, they stared into space while several minutes passed.

"Again, Destiny, I'm just so sorry" said Hannah Thompson eventually.

"What for?" Destiny Rapana replied vacantly.

"You know. The whole forced-impregnation thing," mumbled Hannah. "And for destroying your new panties. And your bedspread."

"Oh yeah, that." Destiny paused for a moment. "I'm sorry too."

"What for?" asked Hannah.

"You know. That you got tentacle-raped in both holes by our unholy demon spawn."

Hannah pondered for a moment. "Actually, that part was quite nice at first."

"Oh."

More time passed.

"Do you think that your dick-sprouting thing was a one-time deal?" asked Destiny.

Hannah certainly had no plans to drink any more of that vile Japanese concoction. "I hope so. I feel normal now."

"Did you get any monster sperm inside you?" pressed Destiny.

Hannah looked down at her pussy, which was leaking thick white goo into a large puddle on the floor between her legs.

"Um… Maybe a little bit…" she replied nervously.

Destiny started inching away…

The End
