Lucy’s Journal

The name is Lucy. I’m your average college student. I’ve become involved in the strangest phenomenon, and I don’t know what to do about it. It all started when I woke up one morning. I was still tired after staying out the night before. I know that something happened before I went home after midnight, but I was too tired after dancing to remember any of it. I’m attending an in-state women’s college, and my apartment is downtown. Close enough to campus that I can walk there, between there and the local nightlife.

I heard my alarm telling me to get up. Classes didn’t begin until later in the day, so I had time to recover after last night’s party. I woke up, and, as I moved towards my alarm clock, I ended up accidentally pushing it off the nightstand. I hurried to pick it up, and made my way towards the shower, taking off my clothes and starting the hot water. Steam filled the bathroom, and I stepped inside. Nothing like a morning shower to help one feel refreshed. I found myself waking up and coming to my senses beneath the hot water, and grabbed the half-used bar of soap from the shower side.

My hands were lathered up, and I ran them across my body. I stopped when my hands passed underneath my boobs. I wouldn’t say I had the most impressive pair of boobs in the world, but they were a good size and shape. Perky for a girl my age. As my hands pushed underneath them, I noticed they felt bigger. I was still in the age where I could have a growth spurt, but this went beyond a minor growth spurt. I felt like I had gained an entire cup size overnight. I stopped what I was doing and turned off the running water, making my way to the condensation-covered bathroom mirror. I ran my hands across the glass, uncovering my reflection and taking a look at myself.

My boobs had gotten slightly bigger. I hadn’t measured them yet, but I knew they were bigger. My nipples, a shade of reddish-pink, had also gotten bigger. Maybe now more people would look at me. I still had to get to my shift at the department store later that day. This development had taken me by surprise. I got out of the shower, drying off and attempted to fit my biggest bra on. It still barely fit, but it felt tighter around my chest than usual. As I struggled to get my bra on, I turned to my roommate.

“Hey Lu,” said Urch from her desk. Urch had been a girl I went to high school with. She was the opposite of me in many ways. A nerdy girl with glasses and unkempt hair. I didn’t know when she used the shower, because she spent most of her time on her computer. She was into anime, games, that sort of thing. She said she attended most of her classes online and was still getting credits, along with doing some sort of job she refused to elaborate on. She was sitting in her chair wearing only her underwear and a T-shirt, the sounds of her game playing in the background. “You’re looking different.”

“Do my boobs look bigger to you?” I asked, leaning down into Urch’s face. Urch examined my cleavage, giving it that smug, bemused look that only a girl who spent as much time online as her could muster. She turned back to the game, not wanting to get distracted. I heard a sound like “kway!” coming from the speakers.

“You’ve never been the type to rub your boobs in my face, but they do look bigger,” said Urch. “Sure it’s not because you’re ovulating?”

“I’m not supposed to be ovulating right now. And ovulation wouldn’t increase them this much,” I said, holding my breasts in my hands. “Something made them bigger.”

“You were out for a long time last night. It could just be your eyes playing tricks on you,” Urch said. “Give it another few days and we’ll see if your tits are the problem or just your mind.”

“You’re the best roommate!” I said, hugging her and squishing my breasts into the side of her face. Urch blushed a little when I hugged her, and went back to her game. I made my way to my shift at the department store. It was a small, independently owned one that was flexible with its hours. I changed into my uniform, feeling the bulge of my chest pushing out my shirt a little more. My day went as usual, with people walking in and out and looking at me. I saw their eyes going towards my boobs in a way they hadn’t before.

When I made it home from my shift, before leaving for class, I took out the measuring tape from the closet. I knew what my measurements had been the last time I purchased a bra, and asked Urch if she could measure me.

I felt reluctant for her to measure me. We had seen each other naked, that came with sharing the same apartment. This felt different. I took my top off and stood in the middle of our apartment, holding my arms above my head while she wrapped the measuring tape around me. She used the chance to squeeze my tit a little, wanting to feel for herself if they had gotten any bigger. I felt it digging into my nipples. I had no idea they were so sensitive. They felt harder than before, spreading a tingling feeling across my chest.

‘Your measurements are noticeably bigger. You can get by with your old bras if you don’t mind the tightness, but this is an unusual amount of growth. I’ll keep an eye on it for you. If you get any bigger, ask me.”

I was going to hold her to that.

It had been a few more days since Urch measured me. I tried to ask her about measuring me again, but after a while I forgot about it. My breasts hadn’t changed size in a few days, and I was getting used to my new endowments. Big boobs were something that every girl wished they could easily have, and I had come into them on my own. I was walking towards my lecture hall. It was a large one, and I would just be one of many students in the crowd. I had never talked to the professor, just took the notes I needed and went on my way.

I entered the classroom with my book and notebook in hand. I was walking up the stairs to my seat, and heard a few students talking among themselves. People were asking if I had gotten a boob job. I thought the change wasn’t that noticeable, but my breasts were undeniably bigger. When I was halfway between steps, I felt it for the first time while I was awake. When my breasts had expanded before, I was sleeping. The only thing I remembered was a strangely erotic dream I’d been having, dreaming of myself topless.

The sensation only lasted for a brief moment, but those few seconds felt like they lasted for an hour. It started with my nipples. I felt them rubbing up against the underside of my bra, going from flat and soft to rock hard in an instant. Though faint, the outline of my nipples could be seen beneath my shirt. My breasts grew hot. The heat started at my hard nipples, spreading outward across the rest of my breasts. I remembered what Urch had told me when she measured me last.

“You went up a whole cup size. That’s normal. Unless you start getting really big, I wouldn’t worry about it. You’re still growing,” she said. I wondered if that was something she had looked up on her computer or if she knew that going in. She spent all day in front of that computer, I wouldn’t be surprised if she picked up all sorts of trivia that an active student like myself is unaware of. As the heat spread across my breasts, the books I was carrying were pushed forward slightly, almost falling out of my hands from being displaced. I caught them at the last second, not wanting an expensive and heavy used textbook to drop on my foot.

I sat down in my chair and waited for the projector to fire up. It was a biology class, and we were expected to know everything for a midterm test that was coming up in a few weeks. I looked down at my notebook. As I stretched my arms, I heard something snap inside. My breasts had gotten too tight for my bra to hold on. My shirt was still barely holding in there. If I flashed the class by accident, that would put my academic career in jeopardy. I hurriedly excused myself before class began, and ran out into the hallway, finding a spot where no one would see me.

Reaching into my shirt, I pulled out my bra. The clasp was still intact, but the bra was too small to be of any use. I would have to go without one for the rest of the class period. I tucked my bra inside my bag, and returned to my seat, acting as if nothing was wrong. The lecture began, and I half-paid attention. I knew that my bust had gone up another cup size. While I adjusted to my new breasts, hanging freely inside my shirt, the girl next to me was taking notes far more intently than I was. She didn’t notice what she was doing.

The eraser tip of her pencil poked against my boobs. It was annoying me, preventing me from taking notes. The boring lecture was already doing that, and I couldn’t focus. She wasn’t trying to hit me with her pencil. My tits had gotten big enough that there was no way to avoid it. I put a smile on my face, and tried to endure it. As her pencil got further down the page, taking more notes with more scribbling, the eraser reached something even more sensitive. My nipples were rubbing against the fabric on the underside of my sweaty shirt, their reddish color faintly visible underneath the bright lights of the classroom.

My face was hot, and beads of sweat were dripping down my forehead. I wanted to let out a little moan, to gasp from the spot she had hit. One of the most sensitive spots on a girl, and mine were even more sensitive after this recent expansion. Her pencil’s eraser had poked me in the nipple. She was one of those students who was so studious that she didn’t notice. I kept up a pleasant, smiling face, despite her repeated poking and rubbing against my tip. The small electric buzz from it transferred over to my other breast, making my other nipple stiffen underneath my shirt.

The lecture finally came to an end, and it was time for us to complete the work given and study in the remaining time. The girl sitting next to me finally took her pencil away from my breast. My nipple was so hot and hard I felt like it was going to tear through my shirt. I held my hand to my mouth, letting out a muffled moan as a wet, sticky feeling filled my panties. The buzz of orgasm rushed through my lower body. She had accidentally made me cream myself, not knowing that she was teasing my nipple. My boobs were too big for her hand to stay away.

I returned to our shared apartment, and put my panties into the hamper to prepare for doing laundry. I needed an entirely new pair of underwear before our next class, and all of my bras were feeling tighter. Urch looked up from her computer at me. “You must’ve had a very pleasant lecture,” she said. “You’ve grown again.”

“I know,” I told her.

Urch returned to her clicking, and I went looking for a new set of underwear.

Journal 3

It had been a week since my breasts were poked in class. I was uncertain how long it would last between each expansion. I felt like I couldn’t get complacent, or they’d grow again. I was heading out to work at Russel’s, the boutique department store where I had been hired. It paid well, and the customers were easy to deal with. The shop sold lots of everyday necessities, with a focus on higher quality stuff that couldn’t be found in the average store. I had always liked window shopping there as a kid, and now that I had enough disposable income from my job, I could afford to purchase some of the things there.

The uniform was feeling tighter around my chest. It had taken some effort to get that last button to connect. My bra was feeling tighter too, but my breasts hadn’t grown any further this morning. The store was a quaint kind of place. I had first been exposed to it as a mall outlet, but the one closer to campus was located in a strip mall. It meant I could take a break and go outside when the air of the store, which smelled like the scented candles sold along the wall, got too intense for me. When I checked in for the day, I saw my boss Ms. Barrett. She was like an older sister to me, and had helped me find an apartment when I started college.

Barrett was a woman four years my senior. She was an alumnus of the same college I was attending, and wore her brownish-blonde hair tied up into a ponytail. She was the owner and manager of the store. Though she was only in her early 20s, people thought she was older than she was. Not in a bad way, but in a MILFy kind of way. She had large, G-cup breasts and a pair of birthing hips, a body that drew people to the store even when she wasn’t trying to advertise it. She had been my guide while I was here, and I couldn’t imagine I would be in the position I was in without her.

“Lucy! You’re looking sharp this morning,” said Barrett. “Are your classes getting you down?”

“I have midterms coming up soon,” I told her, stretching. I linked my fingers together and lifted my arms above my head, working out my joints. Sitting in the car was taking some adjusting to. I couldn’t see my feet and legs as well with my new bust size, and adjusting to their growth was something I was learning one step at a time. I was lucky it was a short drive. “It’s a lot to memorize.”

“Take it one class at a time. That’s how I handle it,” said Barrett. “You look like something’s bothering you.”

I situated myself behind the counter. The store was fully stocked, and we were waiting for our first customer to come in. Until the bell rang, I had time to make free talk. “Do you know of anything strange happening with the nightlife around here?”

“The only thing the news has been talking about is the upcoming bar crawl,” said Barrett. “We’re one of those cities that people drive through, not drive to. I can see what people are saying on the web if you’re that concerned.”

“Maybe I was imagining things,” I responded.

“If something’s bothering you, say it with your whole chest,” she said, placing a hand on my shoulder and giving a knowing grin. There was no way she couldn’t have noticed. I sat behind the retail counter, and waited for the customers to come in.

After working a job like this for months, one eventually gets a handle on the routine. Scanning the items, printing out the receipts, and thanking the customer. Most of our customers were students and teachers who lived at the nearby campus. Someone from one of my classes coming in was common. A lot of them made small talk with me, using the chance to vent about classes or ask about something they were looking for. If it was in stock, I was to direct them to the proper section. My breasts had gotten even bigger since the last time I was here, and the eyes of the people had a tendency to wander downward.

While I was minding my business at the counter, I walked back into the break room. The store was doing alright, but there was a risk of going out of business if we didn’t find something that could bring in a profit. We were just barely succeeding on a narrow margin. Our goods were high quality, but people weren’t looking for high quality. They were looking for cheap and effective, and the other big box stores in the same strip mall could handle things. As I walked into the back room, Barrett turned around with her hands outstretched.

She was reaching for something on a shelf in the break room, and her hands made direct contact with my boobs. When she touched me, I felt another surge of heat inside my breasts. It lasted for only a second, and my shirt stretched slightly more. My breasts had grown again, expanding to a slightly bigger size than before. They plumped out inside Barrett’s hands. She looked at me with a grin, and answered honestly.

“Be honest with me, Lucy. Are your boobs getting bigger?” she asked. I told her everything that had been happening over the past few days.

“That’s normal with a girl your age. They’re still growing,” she said. “You don’t have anything to worry about.” I hoped she was right. I finished my shift at the store, and returned to the apartment. My bra was feeling tight again. I had just purchased this one, too.

Urch’s Journal

If you’re reading this, “Urch” is just a nickname. My hair was frizzy and I tended to cling to the walls during my school years, so I got the name, short for Urchin. I started using it as my screenname around middle school when I first got onto the internet, and I’ve stuck with it since. Nobody calls me by my real name. The only people who see it are the people who cash me my checks. Not even my roommate can remember it. She’s had other things on her mind lately.

I don’t have anything against Lucy personally. There was an incident back in high school where a bunch of seniors chose to play a prank and get the nerdy kids involved. It ended with me having my underwear exposed, and when I turned around to get away, they ended up ripping. If there was any incident that made me want to stay inside, it was that. She who controls the flow of information controls the world, and the internet is the source of all information. All that computer usage means I had to get glasses, which only contributed to the Urchin nickname, but I’m the kind of person who looks better in them.

Lucy’s bed and mine are in separate rooms, with a common room for the two of us. That’s where my PC setup is located. It’s got a high end graphics card and runs up to date. When I’m not logging onto FF14 to play along with my Free Company, I have a side job as a music producer. I started doing remixes for fun before the internet drastically changed, and I was noticed by the right people at the right time. Now I’m composing and arranging music for big stars on the internet and outside it. Nets me a big check each month that fuels my interests and keeps us in this apartment. Not that I’m going to tell Lucy what I do. The kind of music she listens to isn’t all that exciting.

How does my day go? I stay up later at night and wake up later in the morning. By the time I’m up, Lucy’s already gone. In between attending classes online, I have a lot of downtime. Our apartment is well stocked with junk food, and it gives me the energy I need to keep going through the day. Lucy tells me that she’s grocery shopping more often for me than for herself.

When you’re online, no one can tell you’re not wearing panties. I’ve always been somewhat proud of my butt despite the incident. It’s a nice, wide pair of hips that have worn themselves a groove into my chair, a comfortable fit for my ass and no one else’s. I like to tab over to some porn and move my hands between my legs. As long as nobody comes to the door and interrupts me, shlicking is one of my favorite things in the world. The first time I discovered what my fingers could do was a memory that sticks with me. Not a day goes by that I don’t masturbate.

Closing my eyes, letting my fingers wander into my wet slit, and letting them slip inside. Feeling them rubbing against my inner folds and teasing my hard clit. When my clit throbs, I can feel my asshole opening up. I’ve learned the secret to making myself feel good. It starts with a small buzz around my pussy, and keeps growing in size until it reaches my ass, making my entire lower body convulse with pleasure until I’m squirting into my hand. It’s something that should be done multiple times a day. I had finished masturbating for the last time that day when the empty water bottle on my desk rolled off. I accidentally hit it with my hand, sending it between my legs.

I got up to stretch. It was good to get my legs moving every once in a while. This was one of those water bottles that was designed to crumple. I adjusted its position on my chair, and raised my hips into the air. My butt cheeks dripped with beads of sweat, built up from hours of gaming and remixing music. The shadow of my ass was cast across the bottle, and, with a single motion, I moved down to crush it with my butt. The top of the bottle made contact with my ass cheeks, sliding into my rear cleavage. The plastic was smashed down by the force of my hips, becoming a fraction of the height it used to be.

The impact of the once solid bottle against my ass made me cum. Crushing it like that feels so good. Swinging my hips around like a wrecking ball.

I heard a sucking sound coming from beneath me. I looked around the indents in my chair, wondering where the plastic bottle had gone. I spent the next few hours returning to my gaming, feeling a sense of fullness in my ass. It wasn’t until I got up to take a break that I noticed the clear plastic end sticking out of my ass. I bent over and looked into the mirror. I had done it again. I reached my hand into my sweaty ass cheeks, pulling out the crushed bottle and tossing it into the recycle bin. I lightly came again as I pulled the bottle out. The bottle had gotten stuck inside my ass for the past few hours.

This is something I haven’t told Lucy. I have a tendency to lose things up my ass from masturbating with it so much. I like to think of it as another pocket that I can use to keep things safe and warm. Nothing of hers has gone up there yet, but if she keeps dropping things around the apartment, it might happen. It would be her fault for leaving it in the path of my ass.

Journal 4

I was having omelets for breakfast when I felt my breasts expand again. It had been another few days since my last expansion, and I felt my breasts going up another cup size. The bras I had were already starting to be unable to hold me, and I had already purchased a lot of new ones. The bras I brought with me when I moved into the apartment no longer fit. I really liked the designs on some of those, too. I was taking a sip of my morning tea when that familiar hot feeling surged across my breasts, and I felt them plumping out. Each time my breasts swelled, it felt like a miniature orgasm running through my chest. I sort of wanted it to happen, even if it was annoying for my clothes when they got bigger.

Urch was out of the apartment for today. She was the kind of person who refused to go out unless something absolutely forced her to. I had tried to get her to come with me to the party the night that my breasts started expanding. She said there was a time limited event going on inside the game she was playing, and absolutely had to stay behind to make sure she completed it. I let her stay, and now I wondered what would have happened to her if she came along. She had left her computer on while she was out. It was working on something in the background, and she had let it idle off into sleep mode.

Once I had put everything in the sink, I went over to her computer. I was curious what sorts of things Urch got up to all day. Maybe she had a secret porn stash that she was keeping from me. Urch is the kind of person who would encrypt her naughty stuff, and I don’t know what her password would be. She’s very hesitant to tell me much about herself. I let my finger slip towards her mouse, and the screen came alight. It was open to a music folder, full of the kinds of music she had been producing. As I looked at the file names, my chest was feeling tight.

I opened up my top, letting my breasts bounce out. They had gotten a lot bigger since I moved in here. The difference was noticeable. I wonder what my parents would think if they saw me like this. The first thing they’d ask is if I was spending my college money on breast enhancement surgery. Mom, dad, this isn’t surgery. I can verify from rubbing them that my boobs are 100% natural right now. I saw Urch’s headphones. They were still hooked up to the computer. I clicked over to one of her music files, and opened it up. It had a strong bass line, enough that it felt like it would shake the apartment if I played it too loud.

With the weight of my breasts weighing on me, I thought about what I should do. I needed something to soothe my tits. They were still heavy from this morning’s growth. That feeling lasted a few hours. Not quite an itch, but something I couldn’t get rid of. I needed to massage my breasts, to rub them, give them something to help them calm down as my body adjusted to its new proportions. That was when I got an idea. Urch wasn’t here. She wouldn’t mind if I borrowed her headphones and used them as an impromptu massager.

I opened her headphones as wide as I could. Wide enough that they wouldn’t snap. I placed them on either side of my breasts, with the speakers sinking into my titflesh. The soft cushions of her headphones felt really good against my breasts. Better than a bra. I adjusted them on my boobs until they were around the middle. Enough to comfortably hold on, before they slipped off. They were about to get really sweaty, and I knew I was going to make them shake. I clicked over to one of the music files she had been composing, and opened it up.

A steady, bassy beat came through the speakers. It vibrated into my breasts, making them shake and jiggle. They shook like a pair of slightly tanned pudding cups, wobbling as the vibrations spread through them. I could feel it in the entirety of my boobs. The sound waves made my titflesh ripple, going all the way to my nipples. This was the first time I had noticed it. I had my girls out while I was listening to Urch’s music in an unorthodox way, and it wasn’t just my boobs that had been getting bigger.

Every time they expanded, so did my nipples. The tips were rock hard from the vibrations, as big as they could get at their current size. The areola were the size of a quarter, far bigger than they had been the last time I saw them. The steady and repeated vibrations against my boobs were spreading. A burst of pleasure that began at my nipples traveled down the rest of my body, going from my tits down to my belly button, and then all the way to my pussy. The headphones were soaked in my sweat as I rode the vibrations all the way to orgasm.

I moved my fingers around to my nipples, pinching and rolling on those hard reddish-pink tips while the vibrations continued to play through my boobs. I lightly came from the repeated pounding of the bass against my boobs, and fell back from the desk onto my butt. The force of my breasts yanked Urch’s headphones out of the computer. The cable fell down between my boobs, and the headphones slipped off onto the floor. I could still feel those vibrations in my tits. It kept me cumming over and over. I quickly plugged in Urch’s headphones once again, trying to leave the computer the same as it had been when I found it.

Urch asked me why the inside of her headphones smelled like my boobs, but she wasn’t angry about it.
