Otherwise enjoy the story!

Daniel was your typical hot blooded college aged student. Thin, with light amounts of muscle, and a bit of a nerd. His friend Alex was much the same, but with red hair instead of Daniels brown. The two were best friends. They always enjoyed going to bars and hitting on girls, or at least trying to.

They didn't have much luck. They could get a girl or two to look at them, and smile, then maybe chat for a moment, but nothing ever evolved into anything. The two were still happy, if a little bit pent up.

Sure they had a lot of girls they hung out with. They were the put in the 'he's like a brother' category or were 'friend zoned'. They did get to see some of those girls in their underwear though, even though they knew the guys were not gay. There do seem to be some benefits to being friend zoned.

Daniel was getting tired of not finding anyone though. Sometimes he'd even wish Alex were a girl, so at least he had a best friend who was one.

At least until he discovered something special...

- - - -

It was late at night when Daniel got around to checking his email. Mostly random emails from Facebook and other websites he didn't care all that much about. He was about to close out of the page when an email from his cousin Faye showed up.

She was always friendly to him, and they loved hanging out when they had the chance. However, they lived across the country from each other. They did keep in touch obviously.

'Hey Daniel! I stumbled across this little program by accident and had some fun with it. I figured you may like it too so I sent you a copy!' His cousin wrote. He clicked on the link that said 'Master PC'.

It downloaded from the email to his desktop, and he quickly emailed his cousin 'Thanks! I'll see what it's all about.'

He unzipped the file and installed it. It took a short while, but he had nothing to do so he just watched the progress bar. When it finally finished it booted, and loaded into the main screen with the 'Master PC' logo, and a bar labeled 'Name'. Of course Daniel typed in his name and hit enter.

He was surprised to find a nude image of him appear. He didn't have any pictures on his computer. He glanced to his web cam and shrugged “Must be able to register shape or something.” He looked at all the options.

Height, Weight, Muscle tone, Penis size, Gender, Breast size. The list covered both sides completely. Daniel chuckled, going to height and typing in six feet tall, giving himself some muscle and of course making his penis larger just for fun. He hit enter to see what would happen.

He gasped loudly as he found himself tingling all over. His eye level raised on his screen, and his chair seemed smaller as his clothing seemed tighter. He looks down to find muscle tone where there was none before, and a bulge he'd never had between his legs.

He stared for a moment and smiled. He hit the revert option, and let himself return to normal “Okay so nothing is permanent...” He then turned back to the hunk he'd built himself into and grinned. He turned his pheromones up, and turned up his sperm production. Maybe this would all help him get women, being a hunk with muscles.

Daniel smiled, picking up his phone to text Alex. He had to show his friend what he'd found, maybe help him out with the same changes. 'Hey, you have to come over tomorrow. I have something awesome to show you.'

It's a good thing his parents were out of town for the week on vacation. His sister wouldn't be much of an issue either.

Alex arrived the next day “What do you have to show me?” Only to stumble into some big guy who kind of looked like his friend “Daniel?”

Of course Daniel couldn't help but laugh “Yep! Check this out.” he led Alex to his computer, and turned on the Master PC program. “It allows you to alter an image of you as much as you want! I think this might be our way to entice some ladies. It changed me into this big hunk dude, which hopefully isn't over the top!”

Alex stared with a smile on his face “Okay...” Still in disbelief.

Daniel rolled his eyes “It's really me, this isn't a joke.” he then typed in Alex's name, and grinned, pressing the breast size bar, giving him B cup breasts, then hitting enter.

Alex glared “Hey, not cool dude!” then blinked as he felt a warm sensation in his chest. His shirt began to push out as small breasts began to form “What the hell?” he groped them gently “holy shit!” His eyes bugged out “What all can it do?” He didn't seem mad, but he did seem curious.

Dan grinned “anything! It looks like even mind alteration. I'm not comfortable with that one yet though, not sure if it's morally right.” He shrugged “How do you like the boobs?” he snickers to himself, bringing Alex back to his condition.

Alex grabbed them again “I don't know. A little weird that a guys would have boobs. Kinda nice though.” he squeezes them again “can things be returned to normal?” He looked hopeful.

Daniel nodded and pressed the revert button, and Alex's breasts diminished back into his normal chest “Whew. Okay so whatever we do is safe” Alex said, grinning “I have always wondered...” he stopped himself short.

“What? Wondered what?” Daniel poked him in the arm.

Alex got quiet “I've wondered what it would be like to be a woman...” he blushed brightly. Explains why the growing of breasts didn't bother him.

Dan smiled “Do you want me to do that to you?” To which Alex thought about for a moment, then nodded slowly. “Right! Then... We'll make you a dream girl.” He went to work on the image. First he swapped Alex's gender, smirking at the boyish girl on the screen “Well that needs work...” He tweaked on the sliders, widening her hips, plumping up her butt, making her waist narrower, as well as giving her strong thighs, and graceful looking arms. He played with her face a little, making her lips juicy and red, with rosy cheeks and deep green eyes with a small nose to top off the cute and sexy. Next her slid her hair down to her mid back, long and deep red. Of course he saved the best for last, the breasts. He slowly raised the slider, watching the image go from flat chested to A’s, B’s and C’s He stopped at a nice plump DD bosom, with thick inch long nipples and appropriate aureola. Before he let Alex see what he'd done he hit accept.

Alex felt the tingling all over his body immediately. The changes happened in the order of Daniel's decisions, starting with gender. Alex felt his penis and balls pull up into him, forming a perfectly shaped vagina, with a sexy, sensitive little pleasure node at the top under its hood. She gasped as her hips stretched, thighs thickened with her ass, and her waist narrowed gently. Being that Alex had a tight tummy, her belly only became a tight feminine belly, with a cute little belly button she could show off. Her arms thinned a bit, skin becoming softer and beautiful. Her face pulled and pushed in various places, her cheek bones moving to give her those rosy cheeks, and her lips plumping up as if stung by bee's. She raised her arms to feel her hair grow and darken even more from her previous almost orange red hair to her mid back. She smiled at those changes, then moaned as what had been light pecs began to expand, and push outward in her transformers shirt, stretching out the autobot symbol in the front to a faded red and blue. Her breasts seemed to swell forever for her as they pushed through the beginning portion of the alphabet, as if filling with water as they sagged ever so lightly with their new weight.

Alex looked like a girl packed into her boyfriends old clothes. Her shorts that used to go down to her knees had pulled super tight, almost looking painted on down to her mid thigh, button sliding from its hole to make way for the hips that had formed. Her shirt pulled very tight to her chest, the shape of her nipples defined in the white red and blue cloth. Her belly was exposed as the shirt had pulled up, stopping mere inches from the bottom of her now large bust.

Daniel watched all this with fascination, hiding his erection as his dream girl came to life in his best friend “H-How is it Alex...er...Alexis?” he stuttered nervously.

Alex blushed as she ran her hands over her curves, hefting her breasts lightly, before standing and feeling her beautiful ass. “It's different...” she gasped, her voice soft and a little sultry, cute and sexy. “I like it. May want to stay this way for a little bit to see what it's like.” she giggled, stopped in shock, then giggled again “I have a cute giggle!” she grinned “Alexis? I think I like that name for this form.” Daniel watched, fighting his erection, and saving the settings on the program as 'Alexis1' just in case.

“You look... Breathtaking. At first I was just having fun but... Damn.” Daniel looked on in fascination and desire. He was half tempted to alter Alexis' mind to make her think he was her boyfriend. He decided against it of course, on moral grounds. “I didn't think you'd like being big and curvy.” he smiled.

Alexis grinned back “To be honest it feels very nice! It's like I'm meant to be this way.” she giggled, hand on her hip “Seems you like it too.” Pointing to Daniels erection.

Daniel blushed “Um I uh...” he sighed “Well I just watched my best friend become the sexiest thing I've ever seen. Hell I wish you'd always been a girl now that I look at it. It'd be nice to have a girlfriend who could be my best friend.” He looked down, not knowing why he'd let that slip.

Alexis only giggled “Well I wouldn't go that far just yet! But I know I'd have a boner from seeing you become a babe like me. Maybe we'll play with that sometime... But let's not jump ahead of ourselves. We should see how it's worked...”

She giggled, deciding to tease Daniel, who was still bowing his head. She peeled her shorts off, tugging them from her hips and wiggling out of them. Her boxers pulled tight, almost ripping at the elastic waist band. She then pulled her shirt up, revealing first her under boob, then sliding the fabric across her flesh, exposing her nipples, and soon her entire bust. She sat down with a gentle wobble. “You get to see at least. It's your handy work!”

Daniel looked up and his eyes went very wide as he gulped. Anyone else and he would have looked away. He ogled her body, taking in the radiant beauty coming from her. He looked into her pretty green eyes, taking in her striking face. He then traced down to those perfect breasts heaving on her chest. He lingered on her nipples a while before looking to her cute belly and thin waist, then to her hips and thighs, pulling on the fabric of her boxers to near shreds. He was speechless.

She spread her thighs, pulling the fabric to her sex, which was obviously moist, her lips pressing out against the blue boxers “I see that you like it.” she beamed, reaching down to rub at her sex. She gasped softly as she bumped her clit “oh!” she pulled her fingers away “I'll... try that later” she blushed brightly.

Daniel stopped fighting his boner as he watched her. Her hands began to wander over her body, mostly focusing on her breasts. She kneaded them, and hefted them. Her fingers pinched and rolled and tugged on her nipples and aureola “Mmmm...” she wasn't showing off, she was just finding out what it was like “Now I know why girls like their breasts...”

Daniel swallowed “Can... Can I feel them?” He looked hopeful, looking to only cup them, and feel how heavy they were, maybe fondle a little. She looked him in the eye and nodded with a smile. He reached up, hefting those wonderful orbs in his hands. He felt their weight, and blushed “Wow they're really heavy aren't they?”

“Well yeah! You made them huge. Maybe when you get the chance you could make me a little stronger so I can carry them more easilOH!” she gasped as Daniel thumbed across her nipples “That's way better when someone else does it” she panted out. Daniel of course did it again, enjoying the cute moans that his friend was making.

“I may want to keep you this way if you keep sounding so sexy like that.” He Chuckled, tugging on those nipples before returning to squeezing and fondling those wonderful breasts. Alexis only bit her lip, blushing as she enjoyed the sensations coursing through her body.

She spread her thighs “Well obviously I'm enjoying it too...” the boxers creaking at her inner thigh and crotch. The fabric soaking wet as she reaches down to rub her hot puffy lips. She gently pushed Daniel away as she stood, and spinning around she bent over, wiggling her huge sexy rear at her friend. “Care to do the honors? I mean... it is your design...” she giggled “Always wondered how it would feel as a woman.” She winked over her shoulder.

Daniel glanced to the computer, seeing that the mind alteration was not activated. He smiled and shrugged. Who was he to deny a very sexy woman, who happened to be his best friend some sex? He reached out, tugging on the creaking boxers as Alexis leaned on the bed. He pulled them down slowly to reveal her soft, supple ass, and revealing her sopping pussy, and cute little pucker. Her gulped as he dropped the boxers to her ankles, where she stepped out of them.

Daniel licked his lips and leaned in, taking a long lick of her hot, dripping sex. Alexis gasped in surprise. Her legs going weak, falling to the bed with a light creak. He Chuckled, gently licking again, tasting those sweet juices she made, flicking his tongue across her clit. He had no control over his erection while listening to her moans of need.

“Take me Dan...” she wiggled. He stood up behind her, pulling his shorts and boxers off, letting his erection free. He looked into her eyes as she looked over her shoulder, smiling with begging eyes. He positioned himself behind her, about to take his friends feminine virginity, and give her his own.

He slid in, moaning at the heat emanating from her pussy. He slid further in slowly, bumping into her hymen, and before giving her a chance to realize it, he thrust through it, causing her to gasp in pain and pleasure. She moaned loudly, ass flexing, pussy pulsing around his cock. She pushed back against him, taking what was left of his cock inside of her.

Dan gripped her hips, pulling out and starting to thrust into her, feeling her ass squish against his belly as his balls hung free and slapped against her thick thighs. She moaned and squirmed, before stopping him, lifting a leg and in a smooth, careful motion she lifting her leg over his body, rolling onto her back without removing his cock from her pussy. She pulled him up on top of her, squashing her breasts into his chest, pulling him into a deep kiss.

As he was pulled into the lips of his goddess he hesitated, but figured he'd gone this far, so why not? He moaned as she pushed her tongue into his mouth, which he happily sucked on as they ground and bucked against each other. Her mammaries wobbling between them as her nipples pressed against his own. He bucked harder as he approached his orgasm.

He pushed in deep as his nuts clenched and released their pent up spunk. As he released Alexis did too. Her juices coated his cock, balls and thighs as she had her first female orgasm, rocking her body as it rumbled through her form.

The two kissed as they rode their orgasms to completion, and Dan collapsed into her panting as they finished “Th-That was amazing...” Dan moaned, nuzzling her cheek “Does this... make us gay?”

Alexis giggled “Of course not. I'm a woman, and it's as if I never had a penis the way the programmed worked.” she grinned “I don't think I want to be a guy again if this is how it feels to be a woman.”

Dan smiled “Well... you're my best friend. And now you're a beautiful woman, who acts like one. Are you... sure you're okay with this?”

“I am! I've always felt like a feminine boy anyway. I feel more natural like this strangely... With a cock buried in my pussy. I'm glad you didn't need to alter my mind. This feels natural.”

Daniel grinned, tugging her nipple “Good! Then we're a couple now huh?” as he hopped up, his cock slurping from her pussy. He sat at the computer “Looks like there's a little item alteration here...” he fiddles with it, making Alexis' clothing change as it she had always been a girl.

Alexis blushed “I guess that helps up fix the wardrobe issue. I doubt my male clothes would fit anymore. She watched as her shorts and boxers became womens shorts and a pair of purple panties. She giggled, pulling them on with her too tight transformers shirt.

Daniel watched with a smirk “They look great on you. I bet you have a nice sexy panty collection too.”

Alexis thought about it a moment “Oh I do, Boy shorts, Bikini cut, thongs, and a few lacy pieces.” she giggled “Of course I keep boxers too.” she winked. “So... what do you say you... grow me some real boobs?” Hefting her DD's, grinning.

Dan beamed “Oh yeah, they're a little tiny aren't they?” he chuckled, turning to the computer, ramping her breasts up to G's, turning back as he hit the apply button. He began to get hard again as he watched that already tight shirt begin to stretch to translucent, ripping down the middle to expose deep, delicious cleavage. Alexis moaned out as her hands groped at her expanding tits, tugging at her nipples as they grew a little as well. The shirt was on its last leg by the time those orbs reached full size, ripping loudly as they flopped from their confines.

Daniel's eyes nearly popped out of his head as he watched. He got an idea, turning back to Master PC, and turning on medium lactation. He got up, pushing her back onto the bed and latched onto a nipple. He began to suck as he cuddled up to her supple form, drinking down her delicious milk.

“Mm you like breast milk huh? Kinky boy...” She grinned, running her fingers through his hair “So what do you say we go have fun with this program? Maybe get some other girls in on this, or maybe make you one so you can try...” She grinned, rubbing his back as he drank, nodding his head.

He sat up once her got his fill, pulling on his clothing. He sat back at his computer again. Fiddling with the clothing options, grinning as he put Alexis into a bright pink bikini. He hit apply and turned to watch her top pull together, pushing her breasts together as it mended then shrank into a sexy top, tied in the front in a cute bow. Her shorts and panties seemed to melt into the pink bottoms, pulling tight to her large rear.

She wiggled on the bed, sitting up, jumping as a feminine voice spoke “Got a girl finally huh?” Dan's sister giggled as she entered the room “A sexy one at that.” she smiled “I'm Jean” the cute blonde girl said. Jean was sexy, with C cup breasts, and a heart shaped butt. She wore a yellow shirt and tight jeans on this particular day.

Alexis blushed “Alexis...” taking Jeans offered hand.

“Alexis? Did he tell you his best friends name is Alex? Now he'll never forget either name!” she giggled.

Alexis smiled a little “Because I am Alex” she winked, nodding to Dan “Thanks to his little program... and I love it.”

Jean blushed “Funny...”

“I pushed a cake against your boobs on your last birthday. We also shared an event when Daniel got hurt in an accident. We drove to get him together, sharing some personal things I haven't even told Dan...” Of course Dan wasn't hurt bad in the accident.

Jean blushed “oh my god... You got your wish!” she walked closer to Alexis, grabbing a breast “You must be so happy!”

Dan just looked confused. Alexis looked over “I've always felt like I should be a woman. I like both men and women. That's why this feels natural to me...”

Jean leaned in “how does it feel?” Alexis just grinned, before Jean kissed her full on the lips, groping her breasts as she pushed her over on her back. Dan did nothing to stop this. Much to his embarrassment, he thought his sister was a sexy thing, and had some taboo fantasies. He chuckled, watching them run their fingers across each others bodies.

Dan turned to his computer, typing in Jean's name. He glanced over his shoulder to look at her ass, then back to the computer, ramping it up, widening her hips, giving her a bigger firmer rear. He moved to her breasts, pushing them from cute C's up to sexy H's, then his apply.

He turned to watch her clothing begin to pull tight, hips widening to match Alexis'. His eyes wouldn't leave the chest regions of the two babes in front of him as Jean's breasts began to expand and push against the other womans breasts, spreading across them, stretching out the yellow shirt to its limits as her breasts spread across Alexis' G's, stopping at the destined H's.

Jean broke her lip lock with Alexis as she heard the ripping shirt, sitting up to find cleavage consuming her view. The shirt stopped tearing just above and below her nipples. It truly was an amazing sight to see with under cleavage and all. She raised an eyebrow to her brother, who was had a shit eating grin 'Sorry sis. Couldn't help myself. You were sexy, now you're very sexy.” he winked to her, Alexis reaching up and grabbing Jeans breasts.

“Oh!” she gasped, her nipples swelling up “this I could enjoy.” Her smile becoming naughty as she crawled down Alex's body, licking her cleavage, then down to her belly. Jean felt her breasts dragging across the new females body, before dangling free between her legs as she gently tugged on Alexis' bikini bottoms. Jean tenderly flicked her tongue out to taste Alex. She moaned “oooh it's sweet...” she pushed her tongue into her, scooping at her inner walls and pulling her flavor back into her mouth. She blushed “You two fucked didn't you?” Her taste buds lighting up at the flavor of her brothers seed. “I shouldn't. But I like the taste of your cum.” she giggled, wiggling her rear at Daniel as she went back in for more. She licked deep inside Alex's hot sex, tasting her fluids as well as Jeans brothers.

Dan stood up, groping his sisters ass as he got close “Mm fuck me brother...” He looked a little shocked, even as he fondled her rear. He reached around her wide hips to the front of her pants, unfastening them before tugging them down to expose her light blue panties wedging between her cheeks.

Alexis ran her fingers through Jeans hair as she ate her out, moaning and gasping in bliss. Jean was good, nibbling on her lips and clit. Jean pulled back “I've always... had a thing for both of you.” she licked some more “But I couldn't have my brother.” she flicked her tongue across Alexis' clit “And I was too afraid I'd scare you off Alex...” she shuddered as Dan rubbed her pussy through her panties “Now I get you both.” she giggled, sucking on Alex's clit.

Dan grinned, looking into Alexis' eyes, then poking at the computer, pulling up her profile. He prodded at the penis size, and ramped it up to ten inches. Jean gasped as she felt the clit in her mouth begin to expand, first flaring into a cock head, then pushing deeper into her mouth, thick and pulsing. She felt motions behind her as well. Daniel pulling her panties to the side and pressing his cock head against her plump pussy lips, slowly sliding into her.

Jean moaned loudly as she felt her brother penetrating her pussy as Alex's huge cock swelled deeper into her, beginning to push into her throat. She lightly gagged before getting used to it. She began to thrust back and forth between the herm and the male. Her brothers large cock filling her to the brim as she went back, and his best friend turned woman with huge cock filling her throat in the other direction. She whimpered in pleasure, fingers finding Alexis' pussy, sliding into her and wiggling around.

Alexis groaned “Oooh god she's good at giving head.” She shuddered “I won't last long!” Dan meanwhile had his hands on Jeans hips, thrusting into her, balls slapping her thighs. Dan watched his sisters breasts sway beneath her, then up to Alexis and her wobbling bosom bounce with every thrust of his hips transferring through his sister's body into Alexis.

Dan bit his lip, moaning “oooh! I love you sis!” he slammed into her, filling her completely, which caused her to push forward, shoving the herms cock down her throat. Both male, herm, and female came from this. Jeans throat and pussy tensed and squirmed around the cocks as she was filled by their cum.

Jeans belly actually pouched out a bit at the combination of Daniels increased sperm production and Alexis' addition to that count in her stomach. Dan sat in his computer chair, panting. Jeans hips never seemed to want to leave his as she pushed back, letting Alexis' cock free with a loudly slurp, cum dribbling from her lips. She sat back against Dan, feeling his cock deflate inside her slowly “And all those times I almost sneaked in to seduce you two...” she giggled, wiggling her hips and moaning.

Dan reached up to fondle her huge breasts, which had freed themselves from their confines in the fucking she'd just received. “No offense... but I think you look better with just a pussy...” he reached over to remove Alexis' cock and smiled as it became the sexy little pussy it was moments ago. His cock beginning to swell back up into Jeans own hot sex, causing her to moan.

Jean shivered “I think we'll have a much different relationship from now on huh?” looking to her brother as she tightened around his cock, feeling him flex it inside of her. She grinned over her shoulder as she wiggled her hips “How much can this program do?”

Dan groped her breasts as she looked to Alexis and moaned “Anything really. Just have to tweak things in the program.”

Jean licked her lips at that and looked to Alexis, winking “I think I may have an idea...” Spinning the chair with her and her brother in it. She went to town on the program, altering various things across the board. She found what she was looking for and hit apply with a giggle.

“What was that?” Alexis asked, blushing as she feels a tingling in her womb.

Jean just grinned “I'm going to try something fresh...” leaning forward she began licking at Alexis' sex, pushing her tongue deep inside “Fuck me again brother... Fuck me hard as you can.” Dan of course needed no more than that as he began to slide in and out of her.

Jean moans, pushing against Alexis' sex, lapping at her lips as she begins to push in with each of Daniels thrusts. Both Dan and Alexis gasped at the sight of Jean pushing into Alexis, but it only pushed them both into a lustful frenzy. Dan began to fuck her harder, feeling her tighten on his cock. He watched as she began to shrink around his dick, allowing her to slide into Alexis easier. He panted as he grabbed her breasts, feeling them shrink in proportion to her body. Her legs spreading as his cock became larger and larger inside of her shrinking body.

His cock began to bulge her belly as she sped up in her shrinking, only a mere foot tall, only with the cock head inside of her. Her body slurping into Alexis's pussy with one last thrust from her brother as she hit six inches tall.

He forced her into Alexis' womb, and began to fuck Alexis directly now, causing her to buck and moan with her belly rounded out with the foot tall Jean inside her womb, curling up and giggling.

Dan couldn't take it anymore, slamming into Alexis with one mighty moan, sending her and himself into titanic orgasms. Alexis writhed in bliss as Dan gushed into her, soaking his sister inside with his hot seed, filling Alexis to the brim. Her belly bloated out into a dome as he came.

He lay down next to Alexis, panting for breath. He reached out to rub her domed belly, feeling Jean wiggle around inside. Within the womb Jean was absorbing her brothers cum, growing bigger, filling the womb on her own now. She could be heard giggling “oh this is fun!”

Alexis blushed as she rubbed her tight domed belly “You feel good in there Jean... but... how long will you be in there?”

Jean could be heard giggling “Once you've changed me into your dream girl. I'm curious to see what you change me into... It's by thought, not by the program!” she chuckles, wiggling around a little.

Alexis moaned at the wiggling around, squirming on the bed. Her juices were leaking out with some of Daniels cum, soaking the sheets. “Mmm I think I know what I want...” She giggled, winking over to Dan and rubbing her belly, feeling Jean change and shift inside her body. Jean could be heard moaning and felt squirming as she grew and shrank in all the places Alexis wanted. Then Alexis' belly shrank to almost flat as she moaned, pushing.

Dan jumped up “More warning!” he got between Alexis' legs, watching as Alexis pushed harder. He watched her pussy lips part as she orgasmed, a wet little Jean falling into his hands, purring.

He blushed as he held her slowly swelling form. She opened her eyes to reveal that they're a deep purple now, her ears unfurling from under her hair, revealing them to be cute purple cat ears. Behind her the tail she'd grown sprouted. Her wide hips, ass and large breasts begin to swell faster than the rest of her as she moves towards her finished form.

Dan set her on the bed, blushing as she gre to five feet tall, with huge M cup breasts, capped with large thumb sized nipples. She sat up, purring and giggling as she inspected her body “I'm a catgirl! This is cool...” she pet her tail as it dried, becoming fluffy. She looked to Dan and smiled “You like it?” she heft a breast as he watched and nodded. She then crawled over to Alexis with surprising swiftness, kissing her on the cheek “I like what you made me into” she licked Alexis' nose, giggling again, tail scooping across Alexis' sex.

Jean blinked as she felt a tingling in her chest. She sat back on the edge of the bed, watching as milk beaded on the tips of her nipples “oooh am I part cowgirl?” she giggled. Her brother got closer and licked her nipple. She gasped as he began sucking on her breast.

“It's delicious! Alex you need to try this!” Dan grinned.

Alexis sat up and pulling a breast to herself, suckling on the nipple. “Oooh it's very good...” she took it into her mouth again, moaning around Jean's nipple as she moaned along with her. Alexis pulled Jean into her lap, sucking harder on her tit while Dan scooted away to allow for some space.

Jean ran her fingers through her friends hair, moaning softly “have as much as you like.” She then blinked as she felt something wrap around her neck with a jingle. She looked over at her brother who chuckled. She looked down and grabbed at it, finding a cute collar with a bell on it “oooh It's cute!” she giggled.

Alexis pulled back from Jean “Give her a sexy bikini like mine or something.” Dan nodded and went to work. Moments later Jean gulped as she felt fabric spread across her bosom, ass and crotch. She looked down to fine a light purple bikini top and matching bottoms cupping her rear.

“You have to dress with these from now on” Dan grinned, patting her huge breast.

“Yes master...” she giggled, the kitty girl wiggling affectionately against the two. She hopped up and mewed “I Think Dan needs to change.” she grinned, slinking up to her brother, pressing her form against his beefcake one. She pulled him in for a deep kiss, pulling him to the bed to allow Alexis to hop into his chair and pull up his profile.

Alexis giggled as she fiddled with his changes in between glances to watch the heavy petting session between the two siblings behind her. She smirked as she found the anthropomorphic options. Her pussy grew moist as she put the option to bull, beefing up his muscles, and of course making his cock and balls much larger. She added sperm production beyond what Dan had previously set it to, and set down time to minimum.

Alexis giggled madly as she played with his cum, adding side affects to those who ingest it and those who take it into their womb. She hit 'apply' and spun around to watch.

Dan was busy groping his sisters ass as he pushed his tongue into her mouth, cock swelling against her sex through the bikini bottoms he'd given her. Jean moaned deeply when she felt his tongue grow wider, and thicker in her mouth, then feeling his cock thicken against her sex. She purring as she felt his muscles bulge out against her bulging breasts. Her hand traveled atop his head to find small horns forming on his head. He snorted a little at the pleasure of someone rubbing his horn, his thickened fingers reaching down to pull her bikini bottom off her snatch, before thrusting his huge foot and a half long cock into her tight kitty sex.

He moaned out at the tightness, while she moaned out at his thickness. She lost herself in pleasure, moaning out as she tried to take as much into her as she could. Her belly bulging larger as his cock pushed deep into her body, leaving heavy globs of pre seed inside of her.

He grabbed her hips, beginning to pound into her, suckling on her tongue as he manages to push his entire cock into her pussy. He listens to her hips slapping into his own, his balls swinging.

Alexis crawled onto the bed, making Jean sit up on that cock. Alexis settled her face on Daniels face, feeling his tongue quickly start lapping at her sex, pushing in deep, tasting her inner walls. Jean leaned in and began kissing and fondling each other while Dan fucked them both. The two wrestled with each others tongues, their breasts squashing into each others.

Jeans tail teased Dans balls as he fucked her, getting closer to his orgasm, pre making Jeans breasts tingle as they grew from Alexis' changes. He bucked, nibbling on Alexis' clit as he forced his cock entirely into Jean.

He released, holding her hips to his as his spunk forced its way into her womb, bloating her belly up like a balloon. She shivers, cumming around her brothers dick. Alexis giggled into her mouth as she held Jean close, cumming from their cue. Her juices soaking Daniels face as she grinds against him.

He moaned as his huge deposit finishes inside his sister. The two girls pulling off of him to let him breathe. He moans “Oooh I like what you did...” he chuckles, looking to his sister as her tits began to double in size. Her belly having pushed out to nine months pregnant, before absorbing all the cum in her belly into her huge breasts.

He moaned, cumming at the sight, coating everyone on the bed in his seed “Ah!” he blushed. He rubbed his cock “Does this thing ever come down?”

Alexis grinned, licking the cum from her lips “Not until we reverse it on Master PC. I made it so you have a minimal recovery time and cum heaps!” she leaned in, kissing his cock head gently “We won't leave it on all the time of course...”

Jean sat there licking up everything she could reach on herself, then climbed onto Alexis to lick at her cum covered body. The two moan and squirm against each other as they licked at Daniels seed all over their bodies. Alexis parted from Jean to turn off the permanent raging boner while Jean went to lick her brother off, getting as much sweet and salty spunk off of him as she could. He let her, moaning as he relaxed. His body slowly becoming less seed covered by the second. Jean was leaving his chest for last, then gasped as she looked up to see his chest sprouting in breasts.

Daniel looked up and blushed as his body began to feminize. His thighs plumping, face softening, and chest swelling. He moaned as his cock dwindled into his body, leaving a wet little slit where it used to reside. She whimpered a little, mooing softly as she became a rather busty cowgirl. Her breasts full of milk for the kitten and human.

She looked up at Alexis, who smiled down at her “It's your turn Danni.” she giggled, latching onto an H cup breast, sucking on her nipple for some delicious milk. Danni moaned, squirming underneath them as Jean began to suck at the other nipple. The purring was sending Danni wild as it vibrated through her bosom.

Alexis slid her hand down between Danni's thighs, then slipped a finger inside of her. Danni pushed her hips forward in surprise pleasure. She moaned out “Now I know what you were talking about.” she shivered in bliss, mooing softly.

“Now we'll need to get you some cock to enjoy.” Alexis grinned, bouncing to the computer and pulling up Jean, giving her a massive foot long cock, and hitting 'apply'.

Jean moaned as she felt her new member forming. It had the same sperm production as her brother had moments before. Meaning this was going to be a lot of fun as she climbed on top of her brother turned milky cowgirl, pressing her cock head to her nethers and gently pushing in.

Danni gladly spread her thighs. She groaned at the sudden invasion. “That's something to get used to” she moaned out. Her sister giggled, leaning in to kiss Danni as she began to push into her, past her hymen and into her depths. Her pussy stretched around that massive cock her sister carried.

Danni couldn't help but moan deep into her sister as Alexis returned to suck at a free breast. Jean began to fuck Danni with more urgency. All breasts involved jiggled with each thrust. Milk leaked between the sisters and their friend as Danni was pleasured in a way no man could ever enjoy.

Even Danni was having second guesses about being a male again as her sister pushed that huge cock deep into her young body over and over. She couldn't last long as she orgasmed, soaking her sisters cock and lubricating the passage further.

Jean didn't take long to take advantage of this as she began to thrust harder and faster. Her breasts squashed firmly into Danni's. Alexis pulled one away just enough to suckle at the cowgirls milk. Jean was not trying to last long as she approached her first masculine release.

Danni screamed out as she came again, feeling her sisters hot cum pushing up into her body and filling her womb. Her belly began to push out from the volume of cum, but having the same properties as her male sides seed it began to absorb and cause her breasts to expand.

Jean collapsed onto Danni, nuzzling her breast. “Wow that was amazing. No wonder men feel sleepy after sex. It's a lot of work!” She giggled softly as she kissed her sibling, rolling onto her side and resting her head on Danni's right breast. Alexis put hers on Danni's Left.

“I think tomorrow will be another big day don't you?” Alexis giggled as she pulled a dry comforter from the floor and covered the three of them as they snuggled in for the night.

“And in a few days our cousin is coming over to visit from Florida.” Danni grinned.

Thank you for reading part one! I hope you enjoyed it. I am already starting part two!
