Rae's Blueberry
by beetlebomb, jackv & others

the muscle happens later in the story, but it is hot.


Mitch cursed himself. He had the ultimate power of all known universes in his hands and he could think of nothing to do with it! All his pubertal brain could come up with involved either girls, sex, his dick or a combination of it. Annoyed he finally gave into the rumblings of his stomach and went downstairs to fetch some food with the Blueberry in his hands. He was just chomping on the sandwich he made himself and staring out of the window for some inspiration when his 16 year old sister Rae entered the room.
"Enjoying your food?" she threw at him in her usual voice that sounded partly offending but still serious enough so that you could never tell. He decided not to comment it and watched her pick stuff from the fridge, pondering what to do with the Blueberry. The only problem was that the sight of his sister's ass when she was bending down and the firm but small tits being displayed when she grabbed something from the top caused his brain to come up with the same ideas as before.
"Bad, bad thoughts." he whispered to himself and closed his eyes to focus, but there she still continued to stretch and bend.
"What'cha say?" she mumbled with a radish in her mouth laying out the content of her soon to be sandwich, but again he decided not to answer.
Rae will have a tremendous orgasm right now but won't notice it at all.
He didn't really want to type that, but once it was typed in he figured why not. At least it would be a good test for the device and it wouldn't harm anyone. So he hit the send button, and immediately realized how wrong he was...
Still standing there like nothing was happening, Rae suddenly started to moan and pant uncontrollably, her hips started to move back and forth and her knees were shaking. The orgasm was so strong, that very soon she started yelling out the pleasure she was feeling, forcing Mitch to be unable to do anything but to stare at her dazed and overwhelmed by the sexiness of the view of his cute sister cuming just like that while she was making a sandwich.
"Anything wrong?" Rae thew Mitch out of his daze in her usual partly insulting voice when she moved to the table. Mitch just stared at her and tried to keep himself from drooling. Rae just shook her head at him, sat down and started to eat her food. Mitch knew without looking that had a rock-hard erection and would be unable to get up soon without causing a scene. Except of course if he used the Blueberry to fix the situation. But his mind already had further ideas how to instead enhance it...
It's not that Mitch had a thing for his sister. Not exactly. Well, not until just a few minutes ago, anyway. Watching her experience an orgasm was downright hot, and because of that, he... sort of found him seeing Rae in a new light. Namely, he now saw her as a readily available test subject for his new toy.
Of course, Mitch was still a pervert, and so his main interests still revolved around girls, sex, his dick, or some combination of these. Being closely related to his target did not change this fact. And it wasn't like he was planning on having sex with her, he just... wanted some eye candy! Nothing wrong with looking as long as I'm not touching, right? He rationalized to himself. Sitting directly across from her, he was offered a great vantage point from which to observe something he was particularly looking forward to. He wasted no time in entering his new command into the Soothsayer app.
Rae has large, beautiful breasts.
And just like that, her tee shirt began to inflate. It wasn't exactly a rapid process, but it still happened at a noticeable pace. The small bumps that had been tenting Rae's shirt before swelled outwards, gradually sticking out farther and filling out in all directions. As her boobs grew they pulled her shirt tighter and tighter, which showed off the fact that they were become rounder. Mitch could see the outline of her bra consistently keeping up with her expanding assets, seeming to get more snug while at the same time growing along with their contents so that they could effectively contain them. When all was said and done, Rae's formerly modest chest had grown into what appeared to be a full, healthy DD-cup.
Mitch was so entranced by their apparent perfection that he was startled out of a trance when he heard a scoff. He spotted Rae rolling her eyes in disgust, and she crossed one arm over her chest and continued eating with her other. Clearly she was miffed that her brother had been checking her out, and refused to make eye contact with him. Unfazed by his sister's attitude (it was nothing new), Mitch was more concerned over the fact that he couldn't see her tits very well anymore, and sought to remedy this, killing two birds with one stone in the process.
Rae does not mind me admiring her body. She is also much nicer to me in general.
Rae's rigidness immediately softened. Her shoulders relaxed, and she returned with holding her sandwich with both hands. She rested her elbows on the table, and because she had to slouch forward slightly to do this, she adopted a posture that kind of suggested a great view of cleavage. Had the neckline of her shirt been cut a lot lower, that is. Seizing this bit of inspiration (which was, after all, what Mitch had been looking for in the first place) Mitch promptly turned his attention back to his phone. But he paused just before beginning to type. Why stop at the neckline? he questioned himself. Why not go for broke? With a new, much more ambitious idea in mind, he began typing.
Rae prefers to remain in the nude at all times, and feels completely comfortably doing so no matter who she is with.
Mitch almost gasped, because his sister was already naked by the time his focus had shifted from the screen in his lap to the figure sitting across from him at the table. To Mitch's credit, he did not immediately focus on her tits. The first thing he noticed, in fact, were her bare, slender shoulders, which conveyed an odd sense of delicacy and innocence.
Then he noticed her tits. Indeed, they were beautiful, just like he had specified. Since they were no longer confined by a bra, Rae's orbs were affected by gravity under their own weight, drooping forward slightly as she leaned forward against the table, creating a line of cleavage that looked particularly inviting. Suddenly she sighed - a very content sigh - and leaned back in her chair. Still holding what remained of her sandwich in one hand, she let her other drift down to rest against her stomach. Her breasts, then, rested atop her chest, settling to the sides slightly in a very natural way. Mitch couldn't help but admire his sister's breasts. They weren't just beautiful-- they were perfect!
Of course, as spectacular as his sister's boobs were, he couldn't very well do anything but stare at them all day long. After some amount of time, his gaze began to wander. His cheeks burned with embarrassment when he realized Rae had been watching him ogle her. She giggled, though, and continued eating the remaining bits of her sandwich with a smile on her face.
Now that he was over the novelty of his sister having giant breasts... Okay, so maybe he wasn't. But maybe he had ADD or something and he couldn't focus on JUST her breasts for such a long period of uninterrupted time. Well, whatever the reason, he began to take in the rest of the naked upper half of her body. And what he noticed was that her big, perfect, very adult-looking breasts seemed somewhat out of place on her teenage body. Sure, her slender shoulders and arms were cute in their own way, but they simply didn't match her tits. Fortunately, Mitch thought of a simple command that would fix that.
However, he first needed to make sure Rae would stay in the same room as him long enough for him to witness her transformation. Already she was carrying her plate to the sink with the intent on washing it, her somewhat narrow hips shimmying away. It certainly wouldn't take her long to finish, and then she'd be gone. Quickly, he typed out a command that would keep her there longer.
The dishwasher is full of clean dishes, and Rae will take her time putting them away.
She did just that, and Mitch took the opportunity to type out his next command.
Rae has a mature, sexy body that better suits her breasts.
Again, Mitch found himself with the perfect vantage point to watch his sister's transformation unfold. Watching her from behind, he was presented with the view of her hips widening, and her ass enlarging. Her waist remained slim, which served to accentuate her figure to an increasingly alluring degree. It wasn't long before her hips were what one might describe as "rolling", and her shapely posterior was rounder and more plush, while clearly still being firm and toned. Her thighs thickened to a certain degree, developing a sexy amount of muscle tone covered by a smooth layer of fatty tissue that, as the seconds ticked by, begged more and more to be caressed. Her calves, too, received a similar treatment, becoming toned and diamond-like.
As Rae moved around, occasionally bending over to put away some pots and pans in the lower cabinets, Mitch gawked at the sight of her shapely ass flexing and rippling with her movements. And then she'd straighten up, and he saw how much longer her legs seemed. She was taller, actually, perhaps 5'8" by this point. And then when she reached up to put something away on a high shelf, Mitch saw that her arms were slightly thicker with muscle tone, as well as a bit softer. Her shoulders were a little broader, too, but not too much. All in all she definitely looked stronger, and certainly much sexier. In fact, from behind she didn't even look like a teenager! She quite literally looked like a gorgeous young woman! A naked young woman. It wasn't until she turned around to give a Mitch a knowing, mischievous grin - a declaration that she knew damn well he was ogling her - that he saw how youthful and downright angelic her face was. It was sexier, yes, but still obviously that of a sixteen-year-old, and therefore made her seem all the more sexier. She then turned back to her task, taking her sweet time in order to allow Mitch to drink in her beauty as long as possible.
Mitch couldn't help himself. His fingers trembling slightly, he typed in another quick command.
Rae is even sexier.

His mouth suddenly went dry as Rae continued to develop. Her hips widened to an even more devastating shape, to the point where every move she made produced a sexy rolling or a sway. Her legs toned even further, becoming rounder and more luscious. Her arms, too, looked more shapely and sexy. Her back was smooth and beautiful. Her hair, even looked fuller and certainly longer, falling halfway down her back in thick, dark, lustrous locks. Rae pivoted to the side slightly, and Mitch could see that her boobs were growing as well, becoming fuller and rounder while still remaining impeccably firm and buoyant on her chest, jiggling as she bent over to retrieve something from the dishwasher.
And then Mitch nearly choked when she turned around and started sauntering towards him, her over-ripe breasts bouncing with every step, her hips swaying majestically from side to side. She stepped right up to the table he was sitting at, and bent over, giving him an eye-popping display of cleavage. "Want me to get that for you?" she asked.
God, even her voice is sexy, Mitch thought as he gazed into his sister's piercing blue eyes. He gulped. She looked big - taller. "Uh-- N-no, I got it," he stammered, grabbing his plate before Rae could take it from him. He scrambled to his feet, completely forgetting about his raging erection and making no attempts to hide it. The first thing he noticed was that Rae was looking him dead in the eye. They were the same height now, more of it now in her long, sexy legs. Swallowing nervously, Mitch shuffled over to the sink and starting washing his plate, keeping an eye on his sister out of the corner of his eye.
She walked up next to him, where the dishwasher was. She bent over to pull the door up, but didn't leave. She stayed next to him and behind him slightly, and Mitch nearly jumped when he felt a set of insistent fingers grip his shoulder. "It's such a nice day out, I think I'll go for a swim," she practically purred. Without a need for a bathing suit, she made straight for the back door, and Mitch couldn't help but ogle her fantastic backside as she sashayed out the door. He could swear that she added an extra sway to her hips (not that she needed it) for his benefit.
A shiver ran down his spine. Why was she acting so... sexual? He wondered about this. He had specified that she would be nicer to him in general but that itself didn't explain this new behavior. She's outright flirting with me! he realized. Certainly she was expecting him to join her in the pool, and he couldn't deny that he was planning to do just that. In fact, he had already decided that as soon as he was finished washing his plate he'd be running upstairs to find his trunks. But the question still remained. Her body is making her more confident, he surmised, and because she's supposed to be nicer to me... His mind practically reeled, theorizing that the combined elements produced an unforseen side effect to his commands.

Obviously, he saw the potential ramifications of this turn of events, but whether or not this was good or bad, he couldn't say just yet.
In his room, Mitch eagerly stripped out of his clothes, and let his erection hang free in the open air. He paused for a minute, enjoying the sensation of openness, as opposed the constricting feeling he'd had all throughout his episode with Rae.
He eyed his new phone, sitting so innocently on his desk. It's amazing what that thing is capable of! he thought to himself. The things it did to his sister... The things I could do with it. I could do anything to anyone I wanted, to myself if I wanted to... He froze, an idea suddenly forming in his mind. Myself! He literally smacked himself on the forehead, as if the notion of improving his own body was a brilliant realization. He immediately thought of his dick, of course. What perverted young man wouldn't? He looked down at himself, at his six-inch erection sticking out from between his legs. Granted he'd always heard six inches was considered 'average', but really, what bearing did that ever have on a young perverts fantasies to see it bigger? His decision already made, Mitch stepped over to his desk, grabbed his BlueBerry, and booted up the Soothsayer app.
I have a very large dick.

[mondo]

A simple request, but then again his commands about his sister had been simple as well and they turned out great.
Almost immediately his entire groin was awash with a soothing warmth, and Mitch couldn't help but let out a moan of pleasure. Intially he closed his eyes, and he could actually feel his dick stretching, similar to the feeling of getting a strong boner in the first place except that he already had one to begin with. He forced his eyes open, and couldn't help but grin as he witnessed his shaft creeping outward, slowly elongating and thickening. As the fractions of inches piled on, his cock began to droop more and more under its own increasing weight, and the feeling of it being so affected by gravity turned him on even more.
Jeez, how big is this going to get? he began to wonder. But as if that was the cue, his dick stopped growing, extending from his groin nearly twice as much as it used to. Gingerly, he wrapped his fingers around the underside of his shaft, and started sliding his hand up and down its generous length. He was delighted to discover that he was only barely able to wrap his fingers around his own girth. Curious, he grabbed a measuring stick off his desk and measured his new member. True to his command, the BlueBerry had given him a ten-inch penis. 'Very large' indeed, without obscene.
Mitch felt a sudden urge to jerk off. Needless to say having a such an impressive cock was making him horny. But not only that, visions of his sexified sister danced in his hand, touching him in places...
A splashing sound suddenly flitted through his open window, breaking Mitch out of his trance.
Fishing through his dresser, Mitch quickly located his swim trunks and stepped into them. With a little fenagling, he was able to trap the head of his new, impressive (and still erect) pecker under the elastic waistband, so that it wasn't too visible. However, the combination of having his dick grow and the thoughts of his naked, sexy sister meant that his boner was still going strong even after the time it took to walk through the house to the backdoor, and it had slipped loose and was now tenting his shorts obscenely. Before heading outside, he readjusted his junk, hoping that it would stay discrete long enough for him to at least get into the pool. His BlueBerry was clasped tightly in his right hand, available in case he needed to use it.
Outside, he spotted Rae floating on her back in the water - still naked - her new impressive tits breaking the surface and standing out in the sun. Her eyes were closed, and hadn't noticed her brother yet.
Almost immediately Mitch's dick twitched and fell forward again. Impulsively, he made a dash for the pool, hoping to get in before Rae noticed him and saw his massive boner.
But then he slipped. His BlueBerry clattered onto the patio near the edge of the pool and he tumbled into the water face-first, and came up sputtering a moment later, coughing and rubbing the water out of his eyes.
"You all right there, Mitch?" a sexy voice permeated the air. Mitch was surprised to see Rae standing right in front of him, slowly moving towards him with a mischievous grin on her sexy lips. He couldn't help but gaze at her large, perfect breasts, naked and glistening with moisture. She walked right up to him, her mouth-watering orbs a scant six inches from his own chest. He shiver ran down Mitch's spine as he gazed straight ahead into his sister's eyes. He still wasn't used to her being the same height as him, but it made her seem all the more sexier.
Staring into Rae's eyes, Mitch couldn't help but feel a little unnerved by what he had done to her. Not that he was having second thoughts about making her so unbelievably sexy-- no, he was completely satisfied with the way that turned out! The problem he was having was that she still looked so young in the face, and it simply didn't match her otherwise adult body. Chuckling nervously, he started towards the side of his pool. "Dropped my phone," he mumbled. "Gotta make sure I didn't break it." Standing with his back to his sister, he reached over the patio and grabbed his phone, and started typing a quick fix.
Rae is older--
But he paused before he finished. He erased the command, a better idea coming to mind. An idea that was a little bit... kinkier.
Rae is my fraternal twin.
Before sending the command, he turned around, wanting to witness this change as it progressed. He nearly jumped in surprise when he found Rae once more standing just a foot away from him. She had a sly grin on her face, and moved in closer. She snaked her arms over his shoulders, and Mitch nearly came in his shorts when she pressed her large, ripe boobs against his chest. Without taking his eyes off of her, he pressed his thumb over the 'confirm' button and let the phone slip out of his hand and back onto the patio.
And then something extraordinary happened: Rae grew.
He had only expected her face to change. Well, it did. Her cheekbones became more defined, her eyes more mature, her lips a little fuller... Generally her face became more elegant. But Mitch quickly understood that making his sister so sexy at only sixteen years old did not exclude her from the rest of her puberty. And so in aging the five years between sixteen and twenty-one, Rae finished puberty.
She grew.
Mitch's jaw slowly drop as Rae's eyes gradually rose above his line of sight. She was a half-inch taller than him. And then a full inch. And then another. Her body rose as her face matured, and not only that, but the rest of her seemed to join in. Her breasts plumped up a little more, remaining firm and round. Her thighs became a little more muscular, more luscious. Her ass plumped up a little, become heart-achingly sexy and round.
After thirty seconds had gone by Mitch was speechless. His cock ached underwater, pressing against her leg. She looked down at him with a confident, hungry expression, causing Mitch to shiver with arousal. She must've grown at least four inches! Mitch had never really been into tall women before, but he couldn't deny that his sister, at twenty-one years old, carried her six feet and two inches extremely well. Everything about her screamed and oozed sexuality. And her confidence and sense of superiority were such that Mitch began to wonder if he had perhaps made a mistake.
But before he could really consider this, Rae did something that took Mitch by surprise: she kissed him. And not just a tender peck on the forehead, either. She bent down and kissed him on the lips. With tongue. A hot, lustful kiss that stunned Mitch so much that he couldn't bring himself to kiss her back. Nevertheless, Rae continued to kiss him passionately, running her fingers through the back of his hair. By the time she let him up for air, Mitch was completely flustered and gasping for breath. "Wha--? What just...? Why...?"
"Oooh, Mitch..." Rae cooed down to him. She took his hands in hers and guided one of them to her breast, and the other around her waist. "Mmm, little brother," she moaned, "I don't know what it is, but I feel... mmm, really good, you know?"
My sister just kissed me, Mitch thought to himself. Oh god, my sister just kissed me. He couldn't stop himself. His hands were already there, ready to go. Dazed, and looking down into her naked breasts, he sunk his fingers into her ample flesh, appraising their soft firmness. His other hand slid from the small of her back down to her stupendous ass, caressing her womanly posterior.
"Mm, and you know what, bro? I'm really... really in the mood..." She lifted her leg slightly, sliding it between Mitch's thighs so that it rubbed against his erection. "God, I'm so fucking horny today..." she whispered down to him. "Ooh, Mitch? Little brother?" She emphasized the word 'brother', playing off the sense of wrongdoing she could tell was turning Mitch on. "Do you think we could, you know...?"
It was a rhetorical question, as Rae wasn't planning on taking 'no' for an answer anyway. "Mmm, but I think it doesn't matter what you say anyway, because Little Mitch," she whispered harshly, reaching down and gripping Mitch's cock through his shorts, "speaks for himself."
Mitch's mouth opened and then shut, unable to find any words. With a wicked grin and a glint of hunger in her eyes, Rae bent at the knees, sliding her burgeoning boobs along Mitch's torso, and yanked down his shorts. He grunted, his aching erection springing free underwater. Rae stood back up to her full height, looming over him by a good four inches. Mitch tried to speak again, but his sister immediately silenced him with another lustful kiss on the lips.
"I need big brother inside me, Mitch," she whispered huskily into his ear, licking his earlobe. Mitch nearly came right then and there. Suddenly, with a strength that surprised him, Rae gripped Mitch by the waist and lifted him, plopping him back down on the pool's edge with his feet dangling into the water.
His cock now chilled by the open air, Mitch shuddered with arousal. She's so strong! he immediately thought, but then realized that the weightlessness offered by being in the water probably helped her out. Still, though, her newfound size was made evident, and it turned Mitch on even more.
He was completely bewildered as she climbed out of the pool after him. He scooted backwards on reflex, but she quickly caught up to him as she crawled towards him on her knees. She quickly straddled him, bracing herself with her hands on his shoulders as she pushed herself up on her knees, hovering her slick, hairless pussy over his cock.
"Ooooohhh," Rae sighed as she lowered herself down over his cock. Mitch grunted as inch after inch slid into his sister's eager cunt. As the last of Mitch's shaft remained, Rae wiggled her hips, easing in those last couple inches until all ten inches of her brother's cock was inside of her. She settled into his lap, remaining still to relish the sensation of being so filled. Looking down with an expression of accomplishment, she pulled Mitch's head into her cleavage. She held him there and didn't let go, but Mitch didn't seem to want to struggle. "Mmm, you're so big, little brother...!" she exclaimed breathlessly, wiggling her hips a little in his lap as she squeezed her thighs tighter around his waist.
Mitch, for his part, felt like he was heaven, while at the same time knew that he was certainly going to hell. He could only focus on the pleasant feel of her slick, wet breasts against his face and her thick, strong thighs around his waist. She's so big... he thought as he slid his hands around her waist, over her hips, and to her firm, plush ass. A far cry from the bratty, slender teen he used to know.
Rae felt her brother give a reflexive buck of the hips, and gasped at the pleasure. "Oohh, fuck me, Mitch..." she breathed. But the meaning of her words were lost as she began to take matters into her own hands. She pistoned on top of him, seeing stars every time his thick, turgid length penetrated her needy folds. "Fuck me. Fuck me, little brother," she repeated under breath, though still loud enough for Mitch to hear everything.
I can't believe this is happening. I can't believe I'm fucking my own sister, he thought. He continued to bury his face between his breasts, not that he had much of a choice with Rae holding his head there, and never stopped gripping her fantastic rump. Meanwhile, Rae's mantra continued, fueling his arousal by repeatedly referring to him as her 'little brother'. "Rae..." he groaned into her chest.
"Yeah... mmm... little brother?"
"I don't know... I don't know how much longer..."
The knowledge that she was having such an effect on her brother drove Rae wild. She was surprised that she hadn't cum yet already, but she could feel one coming on nonetheless. A big one. "I know, Mitch... Me too... Not long..."
"I'm gonna..."
"I know you are... I want you to..." Sensing her own climax was impending, Rae wrapped her arms around her brother's back ever tighter, aiming to hold him close throughout the experience. "Cum in me, little brother, cum in me..."
"Oh god, Rae..." And so he did. His muscles gave out as the first load of cum erupted from his ten-inch cock into his sister's hungry snatch, adn then only thing keeping him from falling backwards onto the hard patio was her hold around him. Pulse after pulse of cum blasted into her, sending wave after wave of pleasure up and down his spine, and a thought kept repeated in his mind: I'm cumming inside my sister. I'm cumming inside my fucking hot, sexy, twin sister.
"Oh, that feels so good, Mitch..." she whispered breathlessly, referring to both her own orgasm and the sensation of being flooded with her brother's cum. She stopped pistoning on top of him, but took up a light rocking motion, as if coaxing him to feel more relaxed.
The two spent the next several minutes in silence, with Rae holding her brother in a comforting way, and Mitch basking in the warmth and sexiness of his sister's body. Finally, Rae released her grip around Mitch's head, allowing him to withdraw his face from her cleavage. He leaned back a little, allowing the upper half of his body to breathe. He looked up to see the mischievous, naughty smile on her face, looking down with an air of extreme satisfaction for having fucked her own brother. Coyly, she caressed his chest with her palms and fingertips, but did not let him withdraw his member from her sex.
Mitch's thoughts wandered. He looked over to his side and spotted his prized BlueBerry lying on the patio only a foot away. He smirked at the device, and picked it up. He held it in front of his face, between his and his sister's bodies, and grazed his thumb over the shiny screen.
"You did good a job, little brother."
Mitch replied with a small "hm", only half paying attention to what his sister was saying. He assumed she was referring to the sex.
Rae let out a content sigh. "But... I think I'd like to have my phone back now." And with that, she snatched the BlueBerry directly out of Mitch's hands.
Mitch was too stunned to react. She's not supposed to be able to do that! he screamed inwardly. The phone had security features which prevented anybody from stealing it from its owner! So how...? "G-give that back! That's mine!"
Rae simply chuckled. "No, it isn't."
"Yes, it is! It belongs to me! I'm the only who can use it! Now give it back!" Strangely, he couldn't actually bring himself to put forth any physical effort to snatch it back from her.
Rae smiled wickedly, and stroked her brother's cheek with her soft fingertips. "No, you don't understand, Mitch. It really is my phone. I was just letting you borrow it for a little while, to see what you'd do with it!"
"Wait... What? No!"
"I mean, you did a great job! Look at me! You turned me into a fucking goddess, Mitch! I really feel great! I just think you've had your fill, that's all." Rae giggled, and ran her free hand over her body. "Hehehe... Twins. Now that's kinky and clever, little brother."
"But... How...?"
"What, you don't believe me? Here, see for yourself." She held the phone out in front of Mitch, so that he could see the screen.
Mitch squinted, and then groaned in despair. The sceen was a mess! The menu was completely disorganized, the icons were unrecognizable, and the text was undecipherable! "Ugh, I can't believe this..." he groaned, and then fell backwards onto the patio in a fit of depression. But then a thought struck him, and he lifted his head up and peered questioningly up at his transformed sister. "You let me have sex with you?"
Rae's lips curled into a sort of evil grin. "Well, don't be so shocked. It's not the first time we've done it, you know."
"But..."
"I've had this thing for a few weeks now, Mitch. There isn't much we haven't done. You just had your memory wiped after each change, that's all."
Frustrated, Mitch let his head fall back again, but he ignored the sharp sting when it connected with the patio.
Rae smirked, and then pushed herself up. There was a loud 'shlurp' as Mitch's large, limp penis exited her love tunnel, landing with a wet slap against his own thigh. She bent over him, and despite everything, Mitch couldn't help but drink in her amazing curves. She smiled playfully, and extended her hand for her to take. He hesitated, but eventually relented and allowed her to pull him up. "But don't worry, little brother. I won't let your memories reset anymore."
Mitch sulked as his sexy sister wrapped her arm around his shoulders and jostled him. He couldn't help but be reminded of how much bigger than him she was now. A four-inch advantage may not sound like much, but coupled with her outrageous curves and the extra mass that accompanied them, those four inches made a huge difference. And now that he no longer possessed the BlueBerry - more specifically, now that she had the power literally right in her hands - Mitch no longer felt like the in-charge older brother. Indeed, even though he and Rae were technically the same age now, he truly did feel 'little' in comparison.
"And trust me," she continued, withdrawing her arm. Mitch looked up at her, noting with dread her excited expression and the devilish glint in her eye. "We're still going to be having a lot more fun."
Mitch followed her gaze, down her mouth-watering figure to the BlueBerry in her hands. She was typing. "What... Wh-what are you going to do?" he asked nervously.
Rae raised her eyebrows, and grinned wickedly. "Oh, you'll see..."

Mitch felt like his own heart was going to crack his ribcage, it was beating so hard. He couldn't imagine what Rae was going to do with all that power at her disposal. Power he had thought belonged to him... Was she going to do something to him? To herself? Was she going to change some other detail about reality that was going to drastically change things? Mostly he was met with nervousness, but with it came a certain undeniable thrill, deep-seated within his loins.
That thrill intensified when he realized that Rae seemed to be rising. It was the same disorienting shift in perspective from when she had matured right in front of him. On relfex Mitch glanced down at her feet, confirming that they were both still planted firmly and flatly on the ground. And then back up - up further than before - to her steadily rising face. An almost drunken grin was plastered on her heart-achingly beautiful face, her bright blue eyes half-closed and glazed over. Clearly the growth process was a thoroughly pleasurable experience for her.
Rae continued to gain fractions of inches as the seconds ticked by, but she wasn't just getting taller. She was enlarging. As before, figure slowly enhanced to magnitudes of sexiness that Mitch had never imagined possible. Her legs lengthened, and thickened with even more muscle tone and soft, supple fatty tissue. Her hips widened even more, rolling as Rae began to rock them in a slight gyration. Her ass rounded out even more yet still retained its firmness, and the same was happening to her breasts, which were nearly approaching the size of her head while still riding high and buoyant on her chest, her nipples thick and rosy. Her hair cascaded in full, luscious locks, slowly crawling down ever closer to the small of her back.
And the all the while she continued typing, the grin on her lips remaining satisfied, excited, and devilish all at the same time.
Watching this figure of pure sex appeal - who happened his sister - continue to ripen was not without its effect on Mitch. Despite the amazing sex he'd just had, his dick rapidly re-inflated with blood, achieving full ten-inch mast by the time Rae's head had stopped rising. He briefly lowered his gaze to peer straight ahead (into her collar bone) before looking back up to behold her dazed, lustful expression. He estimated her new height to be around 6'8", but that did nothing to convey how massive - and massively sexy - she was becoming.
And still she continued typing. What more could she possibly want to do? Mitch wondered, but he was so enthralled with her beauty that he couldn't help but take the opportunity to drink in her figure. Something about her arms in particular caught his eye. The muscle tone she had accumulated earlier made them look particularly sexy - from the smooth curve of her shoulders and down the sleek surface of her upper arms. As he stared, though, Mitch was shocked to discover that that muscle tone was becoming increasingly noticeable. He heard a sigh from above him, and looked up to see Rae's eyes finally fully closed, and her fingers were no longer working at the device's keypad. She was definitely concentrated on something, though - enjoying something. Again Mitch was drawn to her arms... They were growing! Slowly but steadily, there was increasingly prominent swelling beneath the smooth surface of her flawless skin, becoming thicker and rounder. There was something oddly sexy about the way Rae was gaining muscle mass. Mitch had never been into muscled chicks before, but he couldn't deny that Rae wore her growing strength very well.
When it all stopped, Mitch was practically drooling. Her biceps bulged prominently with the swelling of muscle - not enough to make her look freakish, but enough so that she'd at least rival a fitness model - yet they didn't appear out of place or in the least bit unfeminine. Her skin was still ultra-smooth and silky-looking, and there was enough supple fatty tissue to gloss over the muscle so that there were sloping curves instead of jagged edges. Mitch's eyes roamed over the rest of her body. Rae's shoulders had broadened a little, but still were beautiful. Her breasts actually projected ever further from her chest, due to the extra muscle mass that had accumulated beneath them. Her waist had thickened a little, but it went well with her flat stomach and wide hips. Her abs were noticeably more well-defined, but they weren't too rigged or otherwise offensive to her femininity. Her legs were simply marvels to behold. Long and well-muscled, she looked like she could run a marathon and not break a sweat. Her thighs in particular caught Mitch's eye, as they were thick and round with both fat and muscle, a pair that gave him the urge to bury his face between. And her ass... As perfect as it already had been, it was ever firmer, its roundness now sculpted and emphasized.
By the time Mitch's eyes had returned up to her heart-stoppingly beautiful face, he was practically trembling from arousal. Everything about her now - her curves, her height, her strength, her flawless feminity, and even the way she smiled down at him with pure confidence and satisfaction - all of it served to make him feel inferior, yet still aroused him to no end. His enlarged cock strained with need.
Slowly, Rae licked her lips, her eyes twinkling with her own needs and wants. "Here," she said in a low volume, her voice oozing with sex. She pushed the BlueBerry into Mitch's hands. He accepted it, but looked down at it questioningly. Why is she giving me this? he wondered. His question, though, was answered when she grabbed him by the armpits and lifted him - effortlessly - so they could see eye-to-eye. She held his gaze for a full two second before plunged her tongue into his mouth. His feet dangling below, Mitch's cock strained even harder, poking his enlarged sister in the stomach. Out of the corner of his eyes he could see her biceps swelling with power, flexing from the exertion of holding him aloft.
Despite being confronted with his (apparently) twin sister's overwhelming new size and strength, he couldn't deny that he was thoroughly eager to let things proceed in the direction they were (again) heading, even if in the back of his mind he knew how so very wrong all of it was. I want to fuck my sister, he thought to himself. The thought was as much a warning as it was a statement of desire. Nevertheless, he couldn't help but get lost in the feeling of her big, plush lips against his own. And since his feet weren't touching the ground, he was only partially aware that he was moving, that Rae was taking him somewhere, and so he was disoriented when he suddenly found himself being dropped onto the bench that was attached to their picnic table. The weathered wood scratched against his bare ass, but he didn't care, not while his ten-inch erection was pointing straight up into the air... and his massive sister was descending towards it...
She kneeled in front of him, and Mitch kept his gaze locked into her sparkling blue eyes. "You know, I feel like I need to properly thank you." Mitch watched her pretty lips move as she spoke, mesmerizing in their own way.
"For what?"
"For making me feel so good."
He didn't realize at first that she was leaning closer to him, until he felt the silky soft flesh of her melon-sized breasts brushing against his sensitive shaft. He gasped, causing the grin on her full, soft lips to widen. She didn't fully surround his cock with her titflesh, though. Indeed, she even backed up slightly when Mitch instinctively tried to make his cock slide into her cleavage. She was teasing him, and even let her soft fingertips dance along his shaft without actually taking it in her hands. The last straw came when she pursed her lips and gently blew on the head of his cock, which was mere inches from her mouth. Mitch literally whimpered with desire, and gripped the edges of the BlueBerry tighter. "Please..." he found himself saying breathlessly, despite the strong desire to stay in control of his own actions, especially in dealing with his sister.
Rae's smile went from ear to ear.
Mitch was startled when Rae suddenly snapped the BlueBerry out of his hands. He'd actually forgot that he was holding it, having been lost in her sexy allure. He was suddenly regretting that he hadn't even tried to use it when he had the chance... not that he would've been able to do anything with it, or even had an idea what to do with it.
Rae began typing, but Mitch wasn't paying attention to that. He was too busy being mesmerized by her engelic face, contrasting erotically with her devilish grin. He briefly forgot that he was staring at his sister, because she was so radically different, more mature, from her former teenage self. But the resemblance was still there, and Mitch shuddered as he again realized who this was - his sister, likely the sexiest woman on Earth, and Mitch wanted nothing more than to be ravaged by her. He lowered his gaze away from her face, hoping to distract himself from the notion of familial sex with her huge tits. They were still just inches from his cock, and again he tried to ease it into her cleavage. They'd feel soooo nice... But again she pulled away, her grin widening slightly. At the very least, Mitch felt like jerking off, but Rae's big, strong arms were in the way, busy typing away at the all-powerful device he'd only had a brief taste of.
"There!" she suddenly exclaimed, and set the BlueBerry aside.
Mitch's heart leapt in his chest. He looked around frantically at himself, at his sister, trying to figure out what it was that she changed, but nothing seemed different. "What...? What did you-- Ahhh...!"
His words were cut off as pleasured relief suddenly overcame his aching, straining manhood. It came in the form of heavenly, pillowy warmth - Rae's big, comforting breasts - finally surrounding his cock. He gripped the edges of the bench he was sitting on as she began massaging him with her womanly charms, closing his eyes as he felt his orgasm build... Slowly. Too slowly, in fact. Even when Rae switched to taking his cock into her mouth, using her sexy, pluch lips and talented tongue to massage his needy phallus... Considering how badly he wanted relief, Mitch knew that something like this would've sent him over the edge within a matter of seconds! But no. He tried to let go, but his orgasm was building at a steady pace, almost as if...
As if I have no control over it whatsoever! he suddenly realized. "Rae... Please let me cum..." he coraked. He pried his eyes open just long enough to see the look of naughty satisfaction on her face, confirming his theory on what commands she had just entered. The only thing he could do now was sit back and relish in the wonderful feelings that came with his amazonian sister's alternating tactics. She even took his shaft in her fingers and jerked him off a couple of times.
A combined blowjob, titfuck, and handjob: the trifecta of outercourse.
Although he desperately wanted to cum, to empty the tremendous load that was accumulating in his loins, he couldn't deny how amazing this felt! The prolonged pleasure was definitely enjoyable, and Mitch couldn't help but revel in the waves of pleasure emanating from his loins.
When he finally came - that is, when Rae finally allowed to cum - she moved off to his side, taking his long, hard meat in her strong but feminine fingers, and began to pump him, encouraging him to release pulse after pulse of hot, sticky semen onto the patio in front of them. To him, his orgasm seemed to last a lifetime as he expelled what felt like a liter of cum. Even after there was no more left to give, Rae continued to pump him, slowly, sending shivers of pleasure up and down his spine.
Mitch eventually found the strength to open his eyes, instinctively turning his head to the side he knew Rae was at. She was smiling mischievously at him, still pumping his satiated but still erect cock... He quickly looked down, and boggled at the fact that he was indeed still erect. And not only that, but he felt like he could go again! "Wha...?!" he gasped. "What did you do to me?!"
"Shhhh..." she whispered into his ear. Rae's hot breath on his ear, followed by a flick of her tongue on his earlobe, caused him to shudder. "Just enjoy yourself, little brother. It'll be so much easier if you do..."
Mitch looked at her questioningly, and then shivered again in arousal. He was torn between feeling nervous and belittled, and being utterly turned on by her extreme beauty and... well, her size! Even just sitting, her physical advantage over him was abundantly clear. She was taller, she was stronger, and her sheer sexiness was downright intimidating. And it thrilled him! But that mischievous glint in her bright blue eyes... that was something else. She had plans, for sure. But as to what they were... Mitch could only wait and see...

"Come on," Rae exclaimed, "follow me!"
Mitch found his arm being tugged on as his sister rushed him inside. Her breasts jiggled and bounced from the heightened pace. Small droplets of water from the pool cascaded down her back and flew sporadically through the air as their bare feet thomped down on the rug.
Rae typed away on the Blueberry as they quickly ascended the stairs. Her ass seemed to sway in opposition to the staircase, yet miraculously retained its heart shaped form.
Despite the enticing view, a sense of uneasiness had recently begun to churn in his throat whenever he caught sight of his sibling dabbling away at the phone. He could only hope something good would come out of it.
Mitch could feel the cold wind hit his still wet skin as Rae pushed open her bedroom door, setting the blueberry on the cabinet.
"Sit!" She chirped, throwing him between the bed and her.
Mitch gave her a baffled look, still standing. "Wha-- I-I.."
Rae smacked her lips and rolled her eyes from impatience and promptly shoved her brother down onto the bed.
Before he could react, Rae had swiftly tugged off his swim trunks with one quick, fluid motion. Now with both of them naked and eyes locked upon one another, the result of this situation became very obvious. She wanted to fuck him!
With her knees against the bed, she leaned in to his semi-erect cock and blew air onto it. That alone brought him to full salute.
Mitch was frightened with lust and apprehension. This was his sister! He couldn't just have sex with her, could he?
"Rae, I don't think we shou--" A pillow was shoved in his face.
"Oh shut up, we both know you want it." Rae snapped teasingly at him, and leaned over to press the confirm button on the phone.
Mitch's eyes dashed around the room, to his body, and then his sister, scouting for any changes. There were none. However, Rae was already positioning herself atop her brother.
Her face was drowned in pleasure as Mitch entered inside her.
"I'm gonna c-c-cummm!!!~~" Mitch screamed while involuntarily thrusting inside of her!
"ALREADY?!" Rae barked, "You have to give me some time!"
"I....C-Cant......RR-Rae!!
"Look, just give me two minu-- YAHH!!!"
Rae felt a gush fill her insides as Mitch's body beneath her fell limp.
"I told you I couldn't hold it..."
There was a moments pause from Rae before she spoke.
"It's ok. That was the plan anyways." she grinned down at him while leaning forward to kiss Mitch.
"P-Plan?" Mitch said nervously.
A sudden wave of warm hit Mitch's body.

Mitch's head swam as his entire body started to tingle. The sensation wasn't overpowering, though, not enough to mask everything else he was feeling. His vision blurred, and though he was feeling somewhat lightheaded he could still make out the image of his overtly sexy twin sister slowly growing above him!
Or... On the other hand, the distinctive sensation of Rae's bedsheets sliding against his body was rather suspicious. And that sinking feeling he was experiencing in his very bones... Rae wasn't growing! I'm shrinking! The realization struck him hard, and he couldn't help but groan in frustration. And... well, pleasure. The sensation itself was rather pleasant, and the fact that his sister was gyrating her muscular hips against his still-rock-hard member wasn't helping things.
And Rae was certainly enjoying herself as well. The pleasure she was experiencing herself was evident by the glassy look in her eyes and the grin on her sexy pouting lips. Mitch knew that look. It was the same look she had on her face the last time she grew.
Yup, Rae was growing.
Once the shrinking sensation vanished – which didn't take long, thankfully for him – Mitch rolled out from underneath his sister and scrambled to his feet. He looked around himself, at Rae's belongings, trying to determine exactly how much height he lost. But he just couldn't tell...
The soft giggling made him refocus his attention back to his sister. She was sitting up in bed now, massaging one of her impossibly perfect breasts while lightly caressing her dripping sex with her other hand. Despite his nervousness, his fear, Mitch couldn't help but drink in Rae's out-of-this-world sexiness. He knew it was wrong – for more reasons now than just five minutes earlier – but he couldn't help but feel it: he wanted to fuck his sister again.
With a satisfied sigh, and a proud, almost arrogant smile on her lips, Rae pulled herself out of bed and rose to her feet. Mitch's jaw literally dropped as she stood. He was unable to move, paralyzed with shock, awe, and lust as she stepped towards him. She's so tall... he thought to himself. So fucking sexy... She walked right up to him, so close that his face was literally lost in her cleavage. Mitch had been eye-level with her collar bone after her previous growth spurt. Now he was mouth-level with her nipple. A nipple which she was now pressing into his lips...
All at once Mitch came to his senses. He stepped back, thumping against the closed door behind him. Rae simple smiled. Sweetly, actually, which Mitch responded to surprisingly well. He was still nervous, but at least he was thinking clearly now.
"Don't worry, little bro," she said softly as she stepped towards him again. Mitch's gaze was instinctively drawn to the slight jiggling of her impressive chest as her feet connected with the floor, and he was keenly aware of how forceful his erection was straining in front of him. However, it never occurred to him to think it strange that he still had a boner after such a recent orgasm – and one so strong that it literally drained him of body mass, no less. "You didn't shrink much. Only a couple of inches." She stepped up to him again, once more pressing her body against his.
Now that he was a little bit calmer, he accepted the feel of his twin sister's soft skin against his own with a little less reluctance. She pressed her nipple against his lips again, and this time... well, he didn't feel like fighting just now. So he accepted her nipple and started nibbling at it.
Rae smiled down at him, both pride for her own accomplishments and adoration for her horny 'little' brother backing her smile. "If it makes you feel any better," she continued, stroking his hair, "I grew a bit more than you shrunk."
Mitch looked up to her, his voice nearly catching in his throat: "But why?"
"Think of it like a gift you can give me whenever you want. You cum inside me, I grow more beautiful! Doesn't that sound good?"
Make Rae even hotter? Well, yeah, that did sound appealing, in a twisted sort of way... But still, there was that cost that Mitch wasn't happy about. "But... I don't want to shrink..."
Rae simply chuckled. In a rather demeaning tone, in fact. She smirked down at him, and started backing away from her brother. She couldn't help but smile when she recognized the hurt look on his face. The look that told her he wanted to be close to her. "Come on now, Mitch," she said. She turned around when she got closer to her bed, and looked down at him over her shoulder. She then bent forward, resting her elbows on her bed while she stuck her ass in the air.
Mitch's eyes boggled at the sight before him: Rae's spectacular ass, pointing directly at him. Those wide, alluring hips and her firm, fleshy cheeks beckoned to him. It was literally the sexiest ass Mitch had ever seen, and it was there specifically for him to fuck.
"Don't you want to fuck me, little bro?" she cooed at him. She wiggled her hips, and then spread her legs slightly, presenting her eager sex to him... "Don't you want to make me grow? Don't you want... mm, don't you want to make me a goddess?"
Mitch swallowed hard.
