iVortex - Chapter 9

The heat of Lisa’s body moved over Cameron like a warm blanket, she had laid him on the bed and slowly dragged her body over his. He had no idea what to do, this Lisa had the bubbly joking nature of the sister he knew and loved- but everything else was different. She was so huge and so close, and god why could his dick not stop throbbing. Her voluptuous skin poured over him like weighty satin, only an overmatched bra between them. The heat between her thighs brushed his toes and her red hair fell over his eyes, tickling his cheeks.

“I dyed my hair,” Lisa said softly, “Do you like it?”

Lisa’s pale skin made the red hair seem extravagant, or maybe it was just that her size made everything extravagant. She could have given Erina a run for her money in more ways than one. “I l-like your natural color,” Cameron managed. 

Lisa pouted, her full lips close enough that Cameron could see the tiny lines where they were dry at one corner of her mouth- a minor imperfection that made her beauty and her proximity somehow more real. As if sensing his attention she ran the tip of her tongue over the dry spot, smearing it away with a fresh coat of saliva, her breath smelled of spearmint. Lisa pushed closer. “Oomf,” Cameron groaned as her breasts compressed against his chest. Their weight was incredible, making it difficult to breathe. He looked down and saw that there was not enough room on his chest to support her massive orbs, they spilled over the sides of his ribs and rested on his arms, pinning them to the bed.

“Mmm, that’s nice,” Lisa said with relief. “They get so heavy sometimes, you don’t mind holding them for a bit, do you?” Her voice was ernest, her smile coy. Firm pegs of flesh stabbed into his chest and hardened until they they hurt a little. “I wish you could hold them all the time, wouldn’t that be nice?” Lisa said with a dreamy smile. “I could sit at my desk writing code and you could stand in my lap, holding up my titties.” Lisa giggled at the mental picture she had painted. Cameron’s mouth was suddenly too dry for words.

“That is not what you want though, is it?” Lisa sounded disappointed. “You wanted to come to school, be your own man, live your own life. You don’t need big sis crowding you with her big boobs.” Lisa sighed dramatically. “But, school has not been going so well..”  Cameron tried and failed to swallow the lump in his throat. Lisa’s voice became more and more babying, “Your grades are not very good, you’ve even been missing classes lately. You know I will only pay your tuition if you kept your grades up, but you’ve still been a naughty little boy with those big bad college girls, haven’t you?”

“I d-didn’t, I m-mean-” Cameron stammered. He was not sure what he meant.

Lisa pressed a finger gently over his lips, “Shh. Its okay, I’m not going to punish you. I’m going to quiz you.”

“Huh?”

Lisa grinned. “I want to make sure you’ve been keeping up with your studies.” Her nipples hardened even further and Cameron winced, they were stabbing painfully into his chest now and making cork-shaped indentations in his skin. Her lacy bra offered him very little protection and Cameron watched, mesmerized, as her cleavage welled over the inadequate cups until Lisa’s finger tilted his head up. “Focus lil’ bro,” she said with a knowing smile. “Mmm, I suppose I could quiz you about something you’re interested in. Like… boobies,” Lisa’s tone was equal parts patronizing and playful. 

Cameron felt the color drain from his face, his breaths came in quick short gasps. “You want to know exactly how heavy these are?” Lisa asked, a smug half smile tugging at the corner of her lips. “Lets see, one cubic inch of my boob weighs…” She did some quick mental calculation then said, “about ten grams. ”And lets say I have a cup diameter of twenty two inches.” Cameron nodded, barely able to focus on her words with her hot breath caressing his neck and her turgid nipples grinding into his chest. Lisa on the other hand, was relentless. She said, “So with that information, how much would you say my tits weigh lil bro?”

Cameron tried to concentrate, cubic inches to ounces no he didn’t need to make the conversion oh her nipples were getting even bigger, they were really starting to hurt. Lisa noted his pained expression and said, “Oh are they too heavy for you? I’m sorry.” 

Swallowing the remnants of his pride Cameron said, “Your nipples h-hurt.”

“Aww,” Lisa said and lifted her breasts off his chest. Cameron sucked in a deep breath and was about to thank her when Lisa’s torso plunged forward and his head was buried between her jiggling orbs. “Is that better?” her voice rumbled from her chest. A slender gap in her cleavage was his only source of air and every breath was saturated with Lisa’s smell- a light, but not unpleasant sweat mixed with the faint aroma of cinnamon. Caught between her swollen tits his head heated rapidly until sweat beaded on his brow. He tried to speak but all that came out was an unintelligible mumble.

“You figure it out yet?” Lisa asked over the curve of her massive breasts. His head was so buried in bosom that only a narrow gap allowed light to reach Cameron’s eyes. He could not focus at all. “Can you r-repeat the question?” he stuttered.  

Lisa giggled, sending tremors rippling through her bust. “How much do my tits weigh bro?” A lot! Cameron thought desperately, but he could not say that his sister- no- step-sister wanted a specific answer. Cubic inches, no centimeters... ten grams or had she said twelve… carry the one? “Come on,” Lisa urged, her breath stirring the hair resting on his forehead.

“I don’t know,” Cameron admitted in a rush. “Let me use a calculator.

“Nu uh,” Lisa tutted. “Wrong answer. Next question. I’ll make it an easy one just for you bro,” Lisa’s face scrunched up in thought before she said, “To keep an equal change from your perspective how many inches would I have to grow to equal you shrinking one inch?” The obvious answer that would come to many people was that an inch of growth on Lisa was equal to an inch of shrinking from Cameron, but he knew that was not the case. To use an extreme example if he lost two feet in height Lisa would be nearly twice as tall, but if she grew two feet she would only be around twenty percent taller from his perspective. However, knowing that his shrinking would have a greater impact than her growth- he still had no idea how tall they were and he was more than a little afraid to find out.

“I’d have to measure you,” Cameron said softly. “And myself.”

Lisa clapped her hands together. “That sounds like fun!” she exclaimed and produced a tape measure so quickly it was like she had been anticipating that request all along. Of course she had, Cameron thought grimly. Did he even have to go along with this? He was going to be changing dimensions soon, but was it really a good idea to bring her along? On one hand this Lisa, even though she was not his original sister, was much nicer to him than any of the other girls he had encountered. On the other hand… Lisa shifted and her cleavage surged up over Cameron’s face obliterating his train of thought. Maybe it would not be so bad to have her come along. Especially if she was willing to protect him until they got back to his reality. 

Lisa startled Cameron out of his thoughts by rolling onto her back and hoisting Cameron overhead. “Get that mopey look off your face,” she said. Cameron flailed for a moment until he got his footing. Lisa’s smile widened and she thrust the tape measure into his hand. “Measure me,” she demanded.

“Okay, okay,” Cameron griped. He was trying to be stoic but felt ridiculous with his dick standing at attention bobbing up and down. Lisa surrounded him- her scent, her luscious curves, her mischievous smile, even the rhythmic thud of her heartbeat added to her hypnotic appeal. He pulled the tape even with the crown of her head and muttered, “Hold this please.” Lisa obliged, pressing her thumb over the end of the tape so that it compressed slightly into the mattress. Her legs stuck out well past the end of his bed so Cameron was forced to hop down and measure her from across the room. “Lift your feet please,” he said softly, then had to repeat himself more loudly when Lisa did not respond. Helpfully, she raised her legs. 

Her trunklike thighs stretched before him, thick pillars swollen with enough power to snap his body like a twig. Cameron shuddered involuntarily and moved down to the twin bulges of her calves. Lisa was not an especially athletic girl, but the amount of muscle packed into even one of her calves seemed greater than everything in Cameron’s body put together. Lisa’s feet twitched impatiently and he swiftly stretched the tape measure down to her heel. Cameron’s heart leapt into his throat.

“Eleven feet, one inch,” he croaked. That was bad. From his perspective Lisa was three times his size. That could only mean he had shrunk considerably. 

“Ooo, I grew an inch,” Lisa boomed happily. “Your turn, little bro.” Before Cameron could protest Lisa sat up, snatched away the tape measure and hastily stretched it the length of his body. “Three feet, eleven inches.” Lisa declared. “Same as always.” Always? No, that was could not be right. Had he really lost a foot and a half of height? Cameron could not believe it but at the same time he could not deny the tape measure. He had assumed everything around him was growing to suit the larger than average height of females, but all along he had been shrinking. “So, how much many inches would I have to grow to be equivalent to you losing one inch?” Lisa repeated her quiz question.

Cameron was too startled to think straight, it was basic math but every time he tried to make the calculation the numbers slipped away from him and were replaced with thoughts like ‘How can this be?’ and ‘What am I going to do?”. “Beep!” Lisa declared, making the sound of a game show buzzer. “Time’s up, shorty.”

“Three?” Cameron blurted out.

“Hmm,” Lisa said. “Close, but not exact. Buuut, since you look so cute when you’re nervous I’ll give you half credit,” she declared magnanimously and hoisted Cameron back onto the mattress. Even with the bed beneath him he only reached as high as Lisa’s stomach. He could tell by her arms and legs that Lisa was not fat, but the way her tits stretched her shirt out so far it was difficult to judge her physique by looking at her stomach. Instead his gaze was drawn to the hem of her skirt which was pulled down slightly to reveal the bright pink band of her panties.

“Whatcha lookin’ at?” Lisa said innocently. Cameron’s head jerked up and he saw a smile that was anything but innocent painting Lisa’s lips. “Gosh bro,” Lisa went on coyly. “If I didn’t know any better I would think you were interested in more than tuition money.”

“Of course,” Cameron snapped defensively and felt immediately embarrassed. Lisa was only teasing but he had reacted sincerely. There was nothing to do now but explain himself. “My sister has always been important to me. We are… Were, very close.”

“Hmm?” Lisa said, scooching closer to the bed and forcing Cameron to take a nervous step backwards. “We seem pretty close right now…”

“Th-that’s not what I mean. I mean my real sister, I always looked after her,” Cameron said with as much force as he could muster.

Lisa frowned. “I am her,” she said then looked down at her towering body. “Well, mostly like her. Anyway, it would make me happy if you would think of me the same way as you did her. You can trust me, I promise.” Rather than talking sweetly or using her body to tempt him Lisa said this with a hopeful, almost pleading look. 

No matter how big it was Cameron could not bear to disappoint his sister’s sweet face and so he sighed and said, “Alright...” A second later he was wrapped in a smothering hug, squashed into Lisa’s gargantuan tits and spun in circles until she collapsed back onto the bed, which promptly cracked loudly under their combined weight.

“Oops,” she said. “I’ll get you a new bed. Actually, why don’t you stay with me?”

“Huh?” Cameron gasped as Lisa finally released him from her crushing arms. 

“We’re opening recruitment here so I rented an apartment close to campus.”

“I-I dunno,” Cameron said uncertainly. “Let me think about it?” All of reality was changing so quickly something as basic as moving should not have bothered him, but his room was his sanctuary. Even as reality had shifted dramatically Cameron’s room had remained unchanged. His computer and desk sat in the corner atop a tangled nest of cables, his dresser stood with various drawers opened slightly to allow clothes to spill out like strangely colored tongues, and his bed and its modest twin size mattress- now sagging beneath Lisa’s massive body- had been constant companions. Deliberate or not Lisa was offering to destroy the only consistency left in his life.

Lisa pouted. “Fine, but don’t take too long. Now, where were we?” Cameron was too absorbed in his thoughts to reply and noticing this Lisa went on, “Final question: What triggers the vortex?”

At this Cameron’s head snapped up as if he had been slapped. The vortex, the theoretical hole between dimensions through which he had been falling, was the key to everything. “Tell me, please!” he begged, foregoing any attempt to answer the question. He needed to know. Attempting to deconstruct the alien code left him more confused than when he had begun but if Lisa understood it maybe he could develop some way of reversing the effects. 

Lisa snorted. “I’m nice, but not that nice. You have to at least try before I give you the answer.”

“I don’t know!” Cameron wailed.

“You should know, you’re the one that programmed it,” she scolded.

“Huh?”

“Jeez bro, were you drunk or something when you were working on the machine?”

Cameron felt his face grow hot with shame and looked away from Lisa’s laughing eyes. “A little,” he admitted.

“You… You irresponsible little brat!” Lisa boomed, her good humor evaporated. “I lend you valuable company property and you get drunk and use it like a toy?” Suddenly her proximity and size made Cameron feel very vulnerable.

“It wasn’t like that!” he squeaked. “It was my machine, I built it myself! Things were different!”

Lisa outstretched hand stalled halfway to his collar and she said, “Is that true?”

“Yes!”

“Hmm,” Lisa pursed her lips thoughtfully. “I guess it’s possible given what you did to your mind.”

“What do you mean?”

“Everytime you fall deeper into the vortex you lose a little of your smarts. I don’t know why you would program it that way, but you did.”

“Th-that can’t be!” Cameron said, a wave of panic rising in his chest. 

“Its true,” Lisa boomed confidently. “And do you know what triggers it?” she leaned forward as she spoke, dwarfing him with her titanic, curvaceous body. Cameron shook his head, denying both her claim and the answer to her question. Lisa leaned in until her hair swung forward and brushed Cameron’s lips, her breath was hot against his ear. “Humiliation,” she said. “When a certain someone humiliates you, you get smaller. And you know what else?” Cameron was stunned speechless, unable to move as Lisa’s massive hand wrapped his shoulder. “I think you wanted it that way. I think you like being dominated.” 

The vortex of Lisa’s narrative swallowed Cameron’s soul, was he really the architect of his own suffering? Before he could consider the implications Lisa’s hand pressed down on his shoulder, forcing him to lie upon the bed. “And there’s more,” she added. “You made sure I would be bigger, and stronger, and more successful. You brought yourself here and now you’re afraid you’ve gone too far.” Her final words resonated and Cameron found himself nodding numbly. “I don’t think you’ve gone far enough,” she said softly and the hand on his shoulder slid delicately down to his chest then pinned him forcefully to the mattress. “I made my own little addition to the code,” Lisa said with a smile. Cameron opened his mouth to protest but Lisa was quick to place a finger over his mouth. “I’m not like those other girls Cameron, I’m not going to be mean to you. All you have to do is be a good little brother, don’t disappoint me and everything will be fine.” 

Lisa shifted her body so that Cameron’s legs were forced aside to make room for her stomach. Her bust rested heavily on his torso, making it difficult to breath. “The problem is, dear little bro,” Lisa went on, her tone a strange mixture of regret and anticipation. “I asked you three questions, and you only got half of one right. That was really, really disappointing.” She frowned and a familiar sensation settled in the pit of Cameron’s stomach. The ceiling of his room, warped and twisted as though it were wet paint that a giant, invisible brush was stirring.

Beneath the nauseating flow of the ceiling, Lisa began to grow.

Lisa’s body was suddenly in an island in sea of warped reality, her body was the only constant as Cameron slid through universes. “It’s happening,” she groaned sensually, sucking her lower lip with her teeth. Her voice vibrated through him as her already massive breasts spread across torso. A wall of cleavage rose towards his nose- Cameron’s warm breath was reflected back into his face by the burgeoning swells of breast that swallowed his chin. Soft flesh rolled over his cheeks and he sucked a gasp of air through his lips before Lisa’s cleavage swallowed them.   

“Mmmmmmmmmm.” Lisa’s moan vibrated Cameron’s body as she swelled larger and larger. The weight of her bust was too much! The inflating blimps of her tits crushed the air from his lungs and Cameron panicked, flailing against the underside of her breasts like a squashed bug. Lisa’s laughter rumbled through her tits, sending waves rippling through the cleavage that was swelling closer and closer to Cameron’s eyes. His nose disappeared into the shadowy crevasse between her breasts- he tried to scream but the sound was muffled by a hundred pounds of boob. 

Suddenly he could breathe again. 

Cameron’s eyes opened and saw Lisa leaned back, her monumental assets hanging over him like zeppelins. They wobbled, her nipples tracing playful arcs through the air in response to Lisa’s laughter. “Jeez bro, don’t be so dramatic!” she said when the giggling subsided. “I’m not going to actually crush you.” Her growth seemed to have stopped.

“I couldn’t breathe!” Cameron exclaimed, and tried to scoot away from her monumental tits but there was nowhere to escape, her body trapped him against the bed.

“Aww,” Lisa said mockingly, “Are big sis’ boobies too much for you?”

“You’re heavy!” he accused.

Lisa pursed her plush lips. Her mouth was big enough to swallow his head like a lollipop. “If you’re gonna be big baby I’m not going to play with you,” she pouted.

“I’m not a baby,” Cameron said defensively.

“Then why are you acting like one?” Cameron almost said ‘I’m not’ but realized how childish that would sound. He would only be proving Lisa’s point. Unfortunately Lisa took his momentary silence for agreement. “Oh I know,” she breathed huskily. “You want to be treated like a baby, is that it?” Cameron shook his head vigorously. “No?” Lisa frowned then reached up and pulled the overburdened cups of her bra away from her chest allowing her enormous tits to spring free. Their soft weight bounced onto Cameron’s stomach and Lisa grabbed one huge breast and aimed its fat nipple towards Cameron’s open mouth. “Are you suuuure you don’t want me to baby you?” she cooed. 

Cameron’s mouth worked soundlessly while Lisa’s teat pushed forward and pressed into his lips. He had to open his mouth wider to accept the thick, crinkled nub into his mouth. Almost the size of a soda can it stretched his lips and flattened his tongue. “Mmmmrfffff!” he exclaimed, voice muffled by her huge nipple.

“There there,” Lisa cooed. “Suck.”

With the warm weight of her tits pinning him to the bed he had no choice, Cameron sucked. Lisa moaned softly in pleasure and her hand cradled the back of his head. The next thing he knew Cameron was being lifted up as Lisa flipped over and positioned him in her lap. He tried to break away but her hand held his head in place. “Shhhh,” Lisa said. “It’s okay. I’m not going to punish you little bro. You’ve been a naughty boy but you didn’t know the rules yet did you?” she said, speaking to him like a baby. “From now on you’re gonna do exactly what I tell you, won’t you.” Lisa brushed her fingers through his hair.

She reached down and unzipped his pants, pulling his turgid penis delicately with her huge fingers. Cameron whined and struggled, completely helpless in her arms. “Shhhhh,” Lisa hushed. “I’m gonna make you feel really good now, okay?” She began to stroke his shaft and her already huge nipple swelled even larger, forcing his jaw apart. Cameron breathed frantically through his nose and seeing this Lisa grinned and shoved his entire face into her boob. For a moment everything went dark- he couldn’t breathe. Panicking he struggled but she was too strong. 

The moment before he ran out of oxygen Lisa let him breathe and Cameron gasped around the swollen circumference of her teat. Before he regained his breath jizz splattered all over her hand and he slumped into her arms. “There there,” Lisa smiled. “All better.” She pulled his head back and her nipple came free with an audible pop.

“Now,” she said, suddenly serious. “This is what you’re going to do.”
