I sighed and looked down at my large breasts. My very large breasts, thanks mom. Even in a world where modification to your dimensions was getting easier and easier, I hadn’t been able to bring myself to do anything to ‘my girls’ and so here I was, boobs nearly twice the size of my head, each.





And then there was my roommate, Amanda. My wonderfully open, exhibitionist and energetic cheerleader roommate with the light, brown hair.





A cheerleader without... any boobs. Sure, she had a rocking butt, the kind that would make most of any competing team rubber neck rather than pay attention to the game, whenever she would get her shake on. She just didn’t have the ‘sweater stretchers’ that the rest of her squad tended to sport. Well, I didn’t have sweater stretchers, I had sweater destroyers and... well... A girl’s gotta help her roommate. Sista’s foreva, right?





“Hey, Manda?”





“Queen of Snuggles! Carrrrrrrie!” Why she called me that, I don’t know. “Call me Mandi! Then we match!”





I tried to hold back my laughter. Here I was, all of five foot nothing, dumpy sweats and probably more curves than was really necessary on a frame like mine, my messy blonde hair tucked behind my ears, barely. And then there was ‘Mandi’, Five foot eight, in a workout top that managed to show off what little she had, less than an A if you were being generous, and a set of leggings, in our school colors of course, that were so tight I could see her panties through them thanks to her incredible ass. We couldn’t match less.





“How does that make us match?” I ask with a bit of a laugh. I couldn’t help it, Manda, Mandi, was just too energetic and happy for it to not be contagious.





“Because we both end in E!”





My tits were twice the size of simple ‘E’ cups, so I had to ask and Mandi wasn’t anywhere close. “E?”





“Yah! As in-” She scooped me up in both arms and swung me around, me giving off a startled laugh as she shouted, “EEEEEEEEEEE!!!!!”





“Ok, ok!” I laughed, clinging to her, “put me down!”





“So what did you need?” Mandi tilted her head to the side, giving me a quizzical look reminding me of a dopey golden retriever I’d had as a girl.





“OH! Right.” I blush as Mandi lets me slide down her front, my breasts dragging against her ‘board’. “I teamed up with Karina,” a programming friend of ours, “and made a new app.”

“Ooooh! Like that wizardy one from before?”





I blushed at that. It was supposed to double your intelligence. Instead it had given me two heads. My roommate, rather than let me deal with it on my own, had promptly used it on herself.





Two Mandi’s had almost been too much, but also a lot of fun, and the gesture had meant a lot to ‘us’.





“UH, no, this one lets you move attributes around.”





“Like?” I could see the gears turning in her head. I really hoped it wasn’t her trying to figure out the word ‘attributes’ but I’d seen her puzzle over other large words before. “You can give me your brains?”





I hadn’t thought of that, but I didn’t think so. And I really didn’t want to mess with brains after the last time. “I meant more like our boobs.”





Mandi blinked. “Like you could put my boobs on my back?”





“I... what?” I blinked. How Mandi got from beginning to end on that one I wasn’t sure, but I knew she was going to enlighten me.





“You know, you said move our abbilitbooties around. Like move my boobies to my backies?”





“Mandi...”





“Yes?”





“I love you.”





“YAY!” She scooped me up in another hug and spun me around while I shrieked and laughed, begging her to put me back down. “OK, so how does it work?”





“Just download the app I cloud sent to you and install it.”





A lot of clicking... a lot of questions... and a lot of frustration with someone that I almost... ‘how can I love someone this stupid with technology’ Woah, what? No no, just roommates. Just... yeah…





And as I struggled with that, Mandi finally got it installed. I knew this because she gave a bounce into the air that nearly reached the ceiling, like most of her jumps. If this worked, she could knock a person out with what I was about to give her.





I closed and opened my app again, it quickly finding another phone with the app on in the area and connected to it. What appeared on my phone was paper dolls, sort of, representing me and Mandi. I took a deep breath, gave one last glance at my cleavage, and dragged a finger from my chest area to Mandi’s, and then clicked confirm on the transfer screen.





Before my eyes, the pale wobbly wonders I’d carried around since I was... Well, I was a D-cup at twelve so feel free to do the math on that. Anyway, so yeah, my mountains were becoming hills when I heard the shriek beside me and I realized I’d been missing an equally amazing, if much more magical scene.





Mandi’s breasts... were growing.





I watched with wide eyes as her tight top went from nicely showing off her cute little mounds, straining against her growing breasts.





“Carrrie?” She gave me a look that utterly melted my heart.





“Mandi, are you ok?” I reached a hand out to her, tears were brimming her big blue eyes and I just wanted to pull her to my... reduced chest... and give the best snuggles I could. Instead I put a hand to her upper arm, as usual having to reach UP a bit to do it, as she gave me the biggest smile she could, the tears beginning to fall.





“I... I’ve always wanted... You...” She reached up and with one motion ripped her shirt open, reminding me just how much my roomie worked out... and bought her clothes from BoxMart.

Her newly grown, and growing, tiddehs bounced into view. Unlike my pale, soft, wobbly wonders, Mandi’s were fit and perky, tightly packed and dense with cute peaks of dark nipples. Wow they looked cute. I wanted to reach out and give them a tweak, knowing it’d be a cute ‘Eeep!’ from Mandi. Instead I took a step back and watched as she went from a rather Grand pair of Firm C’s, and graduated into a pair of incredibly firm DDs.





I really lost track of cup size from here. It’s such an arbitrary thing, really, based on rib cage size rather than how big and full the cups really were. Mandi gathered them up in both arms, she had armfuls! And gave them a light bounce. Wow that was cute.





“I’ve got enough to jiggle...” She looked up to me again, back to her breasts, then back to me. “I’ve... I’ve got cleavage... and I’ve got enough to jiggle!”





I laughed as her nipples reached a point that were past her folded arms. “You’ve got more than that, Mandi.”





“I’m a big girl.” If possible, her smile got even bigger. She let go and watched as the gave a light bounce. It was amazing how perky they still were. Mandi definitely had a bit more slope away from her collarbone than she’d had previously, gravity just demanding that she obey some part of the laws of Newton. The bottoms of her breasts were a gentle curve but for the most part they projected forward, perfect and fit for play.





Which was exactly what she was doing. Swinging them around and giggling. “I’m so big, I’m so big!”





I glanced down at my own top. It’d always been baggy but now I was practically swimming in it. I gave a wry smile at my own C-cups. “And a bit to go yet.”





“I... what?” Mandi looked up from her own large pair to see my own dimensioning. I looked very pear like now. A few well-placed genetic markers and a lifetime of chips and Dr. Pepper had left me with plump thighs, wide hips and a pretty plump booty that made it quite comfortable to sit all day and game, and a tummy that frequently made me tug on shirts to make sure they melt my belt loops instead of leaving a self-consciously large amount of pale crescent of skin. I knew what it looked like because I’d seen Mandi pull of that exact thing with her midriffs on purpose. It looked smashing on her, and just reminded everyone else I was fat.





And now, as I became truly flat as a board, I looked up at Mandi with tears in my eyes. I’d given her something that really defined me as me. I was fine with it. Really, I was. It was just... They looked so different on her. They were just these heavy things on me, and on her, they were these perfect, sexy things. Attractive and becoming. Maybe I should just transfer my ass to her too, donate all my best attributes to someone who could really use it and make it look good.





I bet my inches would be happier on her anyw-





“Hey Carrie!”





I looked up and watched as Mandi took a heavy breast in each hand and face planted into her own tits.





For a second there was just silence and then a loud raspberry filled the room as she motorboated her own, large, firm tits.





I couldn’t help but laugh. It was just so... Finally given her desire, boobies, the first thing she does with them is break me out of the funk I was falling into by making me laugh. I... I loved her so much.





“So how about this.” Mandi looked up from her tits, her eyes a bit spinny. “Woah, wait a sec. Light headed after that. Woo!”





I waited patiently for her, handing her a bottle of water from our mini fridge. A few drinks later, a tantalizing drizzle of water running down her chest. She really did look good with boobs.

“Ok, so my idea is this, da bewbs stay with you unless I have a game or a practice.”





“Or a date?” I knew just how much she got around.





“I uh...” Mandi blushed and for I think the first time I’d ever seen, looked bashful. “Nope. Just me on dates.”





“Ok but I’d like to make a provision to that.” I shook my head. How could she turn down those bouncy tits for a hot date?





“Sure?” Mandi tilted her head to the side.





“When it’s just you and me, how about we even things out between us?” I gestured between her heavy chest to my flat one. She gave an emphatic nod and I was just happy to... well.. Ah…





To have... part of me... be part of her. Even diminished.





Like a weight was off my shoulders, off my heart, in more ways than one.
