“Damn…” Vanessa said aloud to herself as the door slammed behind Maddie. Vanessa turned and fell back softly against the door. She held her hands out in front of her, opening them as if cradling phantom breasts. “She was like…out to…here.” Vanessa compared the size of Maddie’s chest to her own, adjusting the distance and bringing her hands closer to her own breasts, realizing she's still somehow larger than Maddie. “Hmm.” Vanessa twisted up her face in deep thought as she refilled her mug of coffee, and then headed back to her room.
Vanessa would typically have class by now, Studio Art. She glanced at the clock and then at the half finished painting in her room. “Eh, fuck it.” Vanessa set down her coffee and went back to painting. As she began to mix colors and apply the paint, getting lost in the process, she found herself thinking about Maddie and her…changes. She imagined Maddie asleep in her bed last night, and how her shirt must have looked as it slowly began to fill with two ballooning masses. Vanessa bit her lip, her lip ring clinking against her teeth. She stepped away from the canvas and stared at it…unhappy with it, not knowing quite yet what it needed to feel “finished”. By the time she took another sip of coffee, it was cold. A couple of hours had passed, easily. “Ugh…” Vanessa let out an exasperated sigh, rubbing her eyes, and making her way to the bathroom.
Vanessa stood and looked at herself in the mirror. Unlike her painting, Vanessa didn’t feel she had anything missing to feel complete. She had gone on quite a journey to reach the point where she felt comfortable expressing herself the way she does– the piercings, the tattoos, the shaggy almost mullet-like hair. She felt confident in her “butchness”, even with her huge boobs. Vanessa lifted her tank top and unzipped her sports bra, letting her breasts reveal themselves again. “Phew… mmph…” Vanessa rubbed her breasts, tender and sensitive from being compressed almost 24/7. She had never exactly been teased for having very big boobs, but she had found them…impractical from time to time, they were heavy and difficult to hide. Over the years, she got into the rhythm of wearing sports bras or binders under t-shirts or tank tops. Vanessa continued to rub her breasts, biting her lip from arousal this time. Her fingers lightly pinched at her nipples; in spite of everything else, she does find herself enjoying having such massive tits. “Fuck, look at these...” Vanessa continued to caress her tits, thinking back to her last couple of hookups and how often those partners would dive at her tits, lapping at her nipples in the dark, making her yelp once they latched on. “Fuck.” Vanessa leaned forward, the corner of the counter tucking right between her thighs– perfect, even pressure. She cooed as she felt the firm seam of her jeans press against her clit with sweet precision. Looking up at herself in the mirror, Vanessa was met with her own blushing face, beginning to glisten with sweat. She started to push down harder against the sink counter, grinding and rocking her hips. Vanessa clutched the counter edge as she pursed her lips with focus, feeling the pressure building inside her. She flipped her shirt up and began to pinch one of her nipples, adding to the waves of pleasure that kept climbing higher until– “Ahhh…fffuck… ah… ah…” Vanessa's hips bucked as she felt her nerves firing before tumbling down to leave her a quivering mess.
Meanwhile… Maddie was making her way across campus, walking briskly to make up for any lost time from this morning. “God, I can’t believe this… People are gonna notice, everyone is going to notice.” With each quick step, Maddie’s new heaving breasts bounced and wobbled under her clothes. “Mmmm…these things are too sensitive.” She glanced down at the hoodie, watching the fabric ripple as her breasts jostled underneath. “Unf… they feel so good, but I… I don’t even know if I wanted bigger tits to begin with. What am I going to do? I should have worn a fucking– OH SHIT.” Maddie clamped her hand over her mouth in horror. “T-t-today is my turn for the presentations. Shit shit shit!” Maddie picked up the pace, squeezing her breasts against herself as she jogged briskly.
Maddie made it to the lecture hall just before class began, and made a bee line for the podium. Her professor, Dr. Lynn, a woman with a cold sneer who never seemed able to get rid of it, gave Maddie an icy stare as she stepped back to let Maddie set up. Maddie threw her backpack down and got out her laptop and papers. Internally, she was freaking out. Fuck fuck fuck fuck fuck fuck fuck. Externally, she was still freaking out, scraping her bottom lip against her teeth and glancing around wildly. Maddie was paranoid that students would notice that the oversized hoodie she threw on was hardly hiding the fact that the garment seemed to be floating several inches away from her, slightly showing off her tummy.
“Whenever you’re ready, miss Simmons.” The professor said with a hiss.
Maddie looked up with a nervous smirk, as she went to stand she lost her balance and stumbled due to the weight of her chest, clutching the podium. “Sh– uh, sorry. Ahem…” Maddie finally stood up on the podium. “He- Hello, my name is Madeline Simmons and my presentation is over–” Maddie trailed off as she looked down at her papers for the next line, but her breasts eclipsed her view. Jesus, how does Vanessa do this? Maddie thought to herself as she cleared her throat and pulled the papers out from under her bust. “...massive objects and their effect on gravity.” As Maddie went on, however, it became clear that the sensitivity wasn't going away. If anything, it seemed to intensify. The fabric of her top felt almost irritating against her delicate mounds, and she found herself unable to ignore it. “The more…massive…the object, the greater the force of gravity… ooh~” Maddie clutched her chest briefly before snatching her hand away.
Maddie continued, she felt a pressure building around her hips, the waistband of her sweatpants digging deeper into her skin. Maddie winced as she tugged and readjusted, feeling the tightness around her thighs and hips building. “Mmph… However… a strong pull of gravity is not always an indication something is very large, which leads us to density…” Maddie felt a strange tension in her already plump behind. “Density describes how –mmph– tightly matter is… ah… packed within a given volume—the amount of space an object occupies.” Suddenly, Maddie felt her underwear begin to shift, pulling deeper between her cheeks. As the tension rose in her thick rump, Maddie felt her underwear begin to rub more against her, stimulating her. “Ah~”
Maddie winced as she tried to shift her sweats around her hips again, feeling how impossible it was to move the fabric in any direction. Maddie began to panic, thinking to herself: Fuck fuck fuck…my ass? Maddie palmed around at her butt, gauging its growth by squeezing it, only to feel that the sweatpants were as tight as a drum. My ass! Another surge of pressure rocked through her lower half, causing her knees to buckle. Maddie was able to catch herself, but not without seeing a sea of confused faces staring back at her. “Ahem… sorry.” Maddie rose to her feet again, as she felt her panties ride even higher between her cheeks, putting pressure against her rim. She pursed her lips as she took a deep breath and tried to continue. “When objects get to beeeEEE–” Maddie’s nipples suddenly tingled before pulsing rhythmically. “...get to be… soooo big.” Maddie shook her head, trying to get a handle on the situation. She looked down at her papers again and again, her chest was blocking her view. Again? How? Maddie thought to herself, as her face turned to shock when she saw the zipper of her hoodie begin to sneak down her chest, the hoodie tightening even more around her breasts. Her nipples began to poke through the thick fabric somehow, prominently visible. “They… they… oh!!” Maddie had to think quickly, yanking at the zipper. “Here– here’s a video demonstrating what I… I… here’s a video!!” Maddie threw on a video as the lights in the lecture hall dimmed. She left the stage, nearly running into Dr. Lynn in the dark.
“Where do you think you’re– OOF!!” Dr. Lynn fell to the floor quickly, knocked over by Maddie's sizable bust.
“D-D-Dr. Lynn, I’m– I’ve…” Maddie offered a hand to lift up her professor, with her other hand pressed against her chest, wincing from the impact.
Dr. Lynn flapped her hands to shoo away Maddie as she stood up. “What has gotten into you, Ms. Simmons?”
Dr. Lynn’s question was answered as Maddie wobbled where she stood, catching her balance. Her hoodie had risen up more, making it appear cropped as her breasts filled any sort of excess space. Maddie’s pants had also stretched beyond belief, giving her an extreme hourglass figure if not for the slightest hint of a muffin top forming.
“Miss…Simmons…” Dr. Lynn trailed off, taking in Maddie’s figure in the dim light. “What has…gotten…into you?”
Maddie chewed her lip as she hesitated to even answer. “I… I… have to go…!!!”
When Maddie got home Vanessa was on the couch, enjoying a mid morning snack. “Hm? Hey Mads, you're back early– Oh my god!” When she saw Maddie this morning, she knew that she had grown, but now...her breasts completely filled the hoodie. What was once an oversized, roomy garment was now stretched to its limits. Maddie stumbled in, looking exhausted and flushed a dark pink. Her breasts wobbled side to side with each uneasy step.
Maddie kept fidgeting with the zipper, yanking it up as it fought against her to inch down from the force of massive jugs yearning to be free. “I don’t wanna talk about it,” Maddie choked out, her face broadcasting how uncomfortable she was. She looked at Vanessa, legs crossed and hunched over in a thin tank top, revealing quite a bit of her breasts. Maddie huffed and stormed off to her room.
Vanessa gawked as Maddie walked away, and saw the shimmying wedgie that followed her. Maddie’s ass was practically swallowing the sweatpants she was wearing. How the fuck? “Maddie wait!” Vanessa sprang up and followed Maddie into her room. Vanessa pushed open the cracked door just as Maddie yanked the zipper down, allowing her breasts to drop slightly while still tightly held close by her tank top. Maddie stood frozen, her eyes wide, wincing as the cool air rushed to her warm skin. “I was uh… I was gonna ask if you needed any help. But…” Vanessa swallowed hard. “Have you seen the rest of you?” Vanessa gestured an hourglass shape in the air and nodded towards Maddie’s wall mirror.
Maddie turned slowly, almost scared to look. She gathered as much of her breasts as she could in her arms, peering into the mirror. Vanessa could see that Maddie’s hips seemed to have grown as well, plumping up her ass and thickening her thighs. Maddie whimpered as she turned to Vanessa. “I don’t know what’s happening anymore, I’m getting scared.”
Vanessa hugged Maddie from the side. “Hey, it’s okay. Do you want to call them?”
Maddie sniffled pitifully. “I-- I logged everything in the app earlier… I haven’t heard back--”
Just as Maddie was about to sob, her phone dinged. Maddie opened her phone, reading aloud a message from the app, apparently from the busty nurse:
Hello Maddie! We’re sorry to hear that you seem to be having an extreme reaction. However, at this point in time it’s nothing to worry about. Any swelling should go down in a few days, if there're any other concerns please let us know! Could you send us your measurements so we can keep track of your fluctuations in size?
“Well, that’s hopefully comforting in some way.” Vanessa tried to sympathize as she rubbed Maddie’s back to comfort her.
Maddie sniffled and wiped away her frustrated tears. “Will you… will you help me?”
“Of-- of course!” Vanessa ran out of the room and quickly returned with a tape measure. “I…hope this will do.” Vanessa lightly touched Maddie’s shoulder, gesturing that she turn around. She wrapped her arms around Maddie’s waist from behind her and brought the flexible metal tape around her butt. She folded the tape together and held it close. “Alright…” Vanessa shimmied the tape up and got Maddie’s waist. “Huh. Alright, turn around.” Maddie turned around and faced Vanessa, her face flushed pink and big, doe eyes looking right at Vanessa. Vanessa went in with an awkward sort of hug, pressing their breasts together before bringing the tape across Maddie’s chest. As she did so, her fingers ran lightly over Maddie’s soft skin.
Maddie moaned slightly, clearing her throat after. “Ahem...sorry.”
Vanessa was blushing a bit. “It’s alright. Okay… Maddie, you’re...bust is pushing 40”, your waist is 32”, and your hips are…52”!”
Maddie said nothing, looking even more flustered. “Um… okay. Vanessa, do you think I could have some uh… privacy?”
Vanessa immediately understood. “Oh-- oh yeah, of course!” Vanessa gently closed the door behind her, leaving Maddie to it.
With Vanessa out of the room, Maddie turned back towards the mirror. This time, she seemed to be admiring her figure. She poked her plush hips, squeezed her butt and felt how firm it was. She untied her joggers and tried to shimmy them off, but even the soft fabric wouldn’t stretch around her hips. She laid back on her bed, kicking her legs in the air wildly. “Come on…mmph!!” Maddie's tits nearly covered her face entirely, eclipsing her view save for her feet if she kicked high enough. Maddie sat up with a frustrated huff, and admitted defeat. “V… Vanessa?” She softly called out.
The door opened almost immediately, Vanessa looking panicked but eager. “Y-yeah? What’s up?” Vanessa was met with the vision of a pair of massive melons smothering Maddie’s face as her legs limply hanged over the edge of the bed.
“I need help… my pants won’t come off!” Maddie kicked her legs one last time, showing the futility in all of her tugging and wiggling.
“Do… do we cut them off? Vanessa asked sheepishly.
Maddie huffed, sitting up slowly as she shifted the weight of her breasts to the side. “I… oof… I suppose we can. It’s not like I’ll shrink by tomorrow.”
“We’ll get answers soon but for now, I’ll grab some scissors.” Vanessa left briefly before returning, snipping playfully.
Maddie rolled over, resting on her elbows so she wouldn’t press all the way down onto her chest. “Just…be careful.” She sheepishly stood bent over the bed, her ass pointed towards Vanessa.
Vanessa hooked her fingers into the waistband of Maddie’s sweatpants, pulling them as much as she could from Maddie’s hips. Very carefully, she began to make small cuts into the fabric. The first cut quickly popped downward, causing Maddie’s ass to suddenly BLOOMPH outward, finally free of the compression. “Whoa!”
Maddie winced, blushing and trying to swallow down her embarrassment. “Vanessa?”
“Yeah?” Vanessa came to Maddie’s side. “What’s up?”
Maddie’s face twisted in a combination of discomfort and burgeoning arousal. “Just…rip them off. I can’t take it anymore, just rip these off of me!”
Vanessa’s eyes went wide as she sprung back up, standing behind Maddie. Her hands hovered around the perfectly round ass pointed at her. Vanessa reached for where she cut and began to pull on either side. Almost instantly, the fabric began to give, small pops and tears hissed their way down and across Maddie’s left ass cheek. The more Vanessa yanked and tore away at the pants, the more flesh began to bubble up and out from the sweats. Maddie’s bubble ass helped the process by pushing from the inside, reducing the sweatpants to ribbons as Vanessa made her way to Maddie’s thighs. She kept grabbing at the fabric and tearing it apart, all while brushing her knuckles up against Maddie’s soft skin. Vanessa glanced all around Maddie’s thickened thighs, taking in the change that her roommate had undergone. Maddie had an ass and wide hips before, but now… she was really big. Vanessa shook her head, dismissing the thought as she finally made her way to Maddie’s ankles, grabbing the scissors one more time to snip through the thicker seams. “There! All done.” The remnants of the joggers fell away from Maddie as her ass was nearly on full nude display, if not for the underwear that had wedged itself deep between her plump ass cheeks.
Maddie stood and turned towards Vanessa, plopping down onto the bed. Her breasts made the tanktop look like a joke of a garment as she cradled them in her arms. “Th– thanks, Vanessa.”
“Anytime!” Vanessa smiled wide, trying to both feel sorry for Maddie while ignoring how hot that was. “Need a few minutes?”
Maddie nodded her head affirmatively, her eyes squinting as she bit her lip.
With Vanessa out of the room again, Maddie let out an exasperated and long sigh. She looked at the closed door and considered…calling Vanessa back. Maddie’s hand crept down between her thighs again. Due to their new thickness, she spread her legs further than she was used to. Maddie grabbed the panties that were stretched narrow over her crotch, and pulled them to the side– which took some doing, given how much they’ve been pulled taut. Maddie began twirling circles around her clit as she felt how sensitive she was– more than usual. With her free hand, she began to squeeze and massage her breasts. Maddie needed to lay down, but knew she would hardly be able to lay on her back due to her new size. Maddie turned onto her stomach as she laid on her bed, burying one of her arms under her breasts so she could pinch and play with her nipples. Her other hand continued to massage circles, with slow but firm pressure. After a few minutes, she slipped a couple of fingers inside. “Mmm… more.” Maddie huffed out as she slipped in a third finger, feeling some slight pressure. Another minute or two of hooking her fingers inside, but she still wasn’t feeling what she knew she wanted. “Ugh… I need more.” Maddie’s pinky joined the effort as she sharply inhaled, feeling that sweet stretching feeling. “Yes…” Maddie’s four fingers pistoned in and out of her, with her thumb tucked against her palm so it would just barely graze her clit. Maddie kept going, deeper and harder…
In the living room, Vanessa turned up the TV to try and drown out the loud moans coming from Maddie’s bedroom. I guess I’m lucky I got the placebo, she thought to herself. But then a small shred of doubt started to grow in her mind: She already had big tits, bigger than most other women she met. But Maddie just-- and overnight! I mean if it’s possible then why not…maybe…go bigger? No, she couldn’t be jealous of Maddie, that would be ridiculous. Maddie seemed miserable….well, at least she did a moment ago.
Maddie was practically in a trance. God… I’m so big. Everything feels amazing. I love it. She sat up, grabbed a pillow and folded it, and straddled it between her thighs. Maddie started to grind against the pillow, riding it as she played with her nipples. “OOOooohhh FUCK!”
Another pleasure filled wail cut through the volume of the TV. Well maybe not that miserable. Vanessa apprehensively picked up the remote again, slowly turning the TV back down, listening to Maddie get herself off. I’m sure her tits are big enough she could suck on them. Vanessa spread her legs and reached under her shorts, imagining Maddie sucking on her own massive tits. She could envision it almost perfectly, and then pictured Maddie hanging her breasts over Vanessa’s face. Vanessa could only imagine how amazing Maddie’s skin would feel brushing up against hers, or how good it would feel to fit her mouth around those growing nipples. Vanessa, now pulling the opening of her shorts aside, started to finger herself as she kept playing with her clit. She wanted Maddie to smother her with those beautiful boobs, and she wanted to suck on them for hours. Vanessa tried to pick up the pace to match Maddie, to see if–
Vanessa heard the click and turn of Maddie’s bedroom door and scrambled for a blanket. Maddie came out of her room, cheeks flushed pink and now resigned to wearing the largest shirt she had and only some booty shorts with it. “Uh, hey. You hungry?”
“Ah I-- I already ate.” Vanessa stammered, hoping that it wasn’t obvious she was just masturbating too. Maddie began to make herself dinner, and Vanessa couldn’t help but feel her eyes drawn to her roommate and that gargantuan chest of hers. She kept looking away so that Maddie couldn’t notice. Once Maddie prepared herself a plate, she plunked herself down on her usual couch spot...next to Vanessa.
“So, uh, how was your day? You want to talk about what happened?” Vanessa cautiously asked.
Maddie rolled her eyes. “It was awful. Everyone was staring at me during my presentation, it just… ah, it sucked.”
“I’m sorry.”
Maddie shoved her breasts together like they were in the way, making them sway under her shirt. “They’re seriously still growing. Like, I had my presentation this morning, right? And I --god this was so embarrassing-- but I could feel these things swelling, and I… I could even feel my ass filling my joggers as I stood up on stage! Which gave me the weirdest yet best wedgie of my life. There was a huge mess and I ran out as soon as I could, it was so humiliating. I knocked my professor over!”
“Oh wow.” Vanessa tried to ignore it the best she could, but she couldn’t help but get turned on by picturing Maddie and her giant breasts growing larger and larger as the day went on. Maddie’s massive boobs wreaking havoc throughout her day, and all those people staring at her–
“Then I– unf…oooh~” Maddie broke Vanessa’s train of thought as she set down her plate and turned towards her on the couch.
“What was that?” Vanessa blinked, trying to focus.
Maddie bit her lip nervously. “It… it’s…nothing.” Maddie’s face twisted in a way Vanessa had only seen just this morning in the mirror.
“You sure it’s nothing?” Vanessa reassured her.
Maddie shifted in her seat. The fabric of her extra large shirt looked strained. “Well the thing is, these things won’t stop tingling. They’re so sensitive, and it's been making me ridiculously...horny. Like, unbelievably horny.”
Vanessa was already picturing Maddie, her panties around her ankles, her huge tits heaving as she got herself off. Vanessa could feel how wet she was getting again.
Maddie rambled on. “And well, I mean you probably heard me so obviously I just... I gotta be very honest with you, I’m already feeling it again. It sucks. What are these things doing to me??”
“I– I don't know, that does sound like it really sucks, I’m sorry.” Vanessa nodded, staring just over Maddie’s shoulder so she wouldn’t catch herself staring at Maddie’s melons.
“You’re so lucky you got the placebo.” Maddie huffed, looking at the nearly silent TV.
Vanessa just nodded. The two were silent for a few moments, watching whatever was on. “I could... help you,” Vanessa said softly.
“Hm? What?” Maddie looked genuinely confused.
Vanessa was instantly worried she had gone too far but she couldn’t exactly turn back now. “If you’re that horny, I could maybe... help? If you think that would give you more...relief.”
“Maybe.” Maddie sounded unsure.
Vanessa sat up and moved towards Maddie on the couch.
Maddie bit her lip. She made eye contact with Vanessa for a surprisingly long time. “Okay,” she murmured as she moved her hands to start untying the knot of her shorts.
“H-- Here, let me.” Vanessa got on her knees in front of the couch where Maddie sat, trying her best not to seem too eager. Vanessa could hear the pulse pounding in her ears, when she reached for the knot that kept Maddie’s shorts tight around her hips her fingers were shaking. She made quick little fists and clamped her lips together to keep her lips from trembling. As she loosened the knot she tucked her fingers under the waist of Maddie’s shorts. Maddie lifted her thickly-padded ass and let Vanessa pull them down and off her legs. “Maddie… wow. You’re getting really thick.” Vanessa started to kiss and caress Maddie’s thighs, the soft skin brushing against the shell of Vanessa’s ears. Her kisses began to trail closer and closer to Maddie’s waist when Vanessa felt something bump her head. Vanessa looked up and Maddie’s head was completely eclipsed by her swollen breasts, still stretching out her shirt. Without saying anything, Vanessa stood up and straddled Maddie.
Maddie yelped. “Vanessa! Wha-- what are you?” Maddie could just see Vanessa’s head crane over her breasts as she got comfortable.
“I told you I wanted to help you.” Vanessa replied with a coy smirk.
Maddie lifted the shirt over her head and her massive breasts, now nearly surpassing J cups. Vanessa was transfixed in awe. Maddie’s skin looked so soft and perfect, and her breasts were so full and swollen. Her nipples were puffy, light pink and standing at full attention. Maddie leaned back and closed her eyes as Vanessa brought her mouth to Maddie’s nipple.
Vanessa made small circles with her tongue. While she sucked, licked, and teased Maddie’s nipple, she reached down between Maddie’s legs. Vanessa’s fingers gracefully maneuvered around and under Maddie’s underwear, her fingers instantly finding her clit.
“Be careful,” Maddie yelped. “Sensitive.”
With her fingers still circling Maddie’s clit, Vanessa took the other tit in her hand and started squeezing, taking in every inch of it. Her hand covered Maddie’s areola and not much else, and Vanessa started thinking about how Maddie could possibly get bigger. Unable to stop herself, Vanessa unlatched from Maddie’s nipple and traveled to the other, swirling it around with her tongue.
Maddie was far away just moaning now, reaching up and playing with Vanessa’s hair. As Maddie gripped Vanessa’s hair, thick locks spilling out from between her fingers, Maddie began to scream, her shrieks of pleasure echoing off the walls of the living room. Vanessa’s fingers around her clit with her mouth latched onto her nipple and sucking away were all too much. She screamed into an orgasm more powerful than she’d ever experienced in her life. “Mmmm oooh my god! Vanessa!! Don’t stop! Don’t stop! Don’t--” Maddie trailed off to catch her breath, nearly blacking out from the waterfall of pleasure.
As Maddie climaxed, Vanessa felt her mouth suddenly fill up with a sweet liquid, and simultaneously felt drops of something splatter the hand that was clutching Maddie’s other breast. She swallowed and looked up. The drops were a clearish white. Vanessa sat up and swallowed what was in her mouth as she inspected the liquid on her hand. “Hey…Maddie?”
“Yeah…?” Maddie said meekly, still panting from the aftershocks of her orgasm.
“Did the doctor say anything about lactating?” Vanessa wiped some of the liquid from her face, chin, and lips– licking her fingers too.
Maddie’s eyes went wide. “I don’t think. Maybe… why?” Maddie peered over her massive rack at Vanessa’s glowing face, milk dripping from her lips. “Oh, I guess I’m... lactating now. Great.”
