Sarah?! What are you doing? “Nothing. Just enjoying myself and trying to attract some cute boys like you hehe~” she replied back after I found her with her breasts out, barely being censored by the thin bikini top that didn’t just break but absolutely destroyed the college’s dress code. Speaking of breaking, it seemed like it was at a high risk of doing her as her giant mammaries were straining it to its limit!

Normally, if I found my friend Sarah like this, she would’ve blushed hard and be insanely ashamed of being found like that, but she had changed quite a bit ever since she tried out a little experiment she made. The two of us teamed up about two weeks ago for an assignment, deciding to delve deep into researching how intelligence is defined, how it works on humans and other animals, and even how to alter it for better or for worse.

I was doing my thing, typing on my keyboard as I compiled sources and added relevant information. Sarah was doing more than just mashing a keyboard though, she’s hella nerdy so I wasn’t too surprised to find her doing who the hell knows what with a bunch fluids and containers at her dormitory room. I was just here to get a degree and get a good paying job while Sarah seemed to genuinely love these topics.

Once the day of the assignment arrived, we did a presentation on everything we found. I just talked a bunch about the topic but this brunette was ready to show off her latest experiment. She showed a small container with a blue fluid in it, explaining how upon drinking it, it would boost her intelligence within the next few days. It was a wild claim, and even I didn’t believe it, but I didn’t want to crush her dream nor did it seem deadly, so I wasn’t too concerned with her gulping that fluid down in front of the whole class.

Everything seemed fine and dandy on the first three days or so. At the time, she had a modest but very cute body. She had a nice pair of C-cups, some decent hips and booty, with the star of the show being her thick thighs and gorgeous face. She wasn’t necessarily my kind of girl personality-wise but I would be lying if I said she ain’t pretty!

On the fourth day though, I noticed she tried to dissimulate adjusting her clothes. Sarah was quite embarrassed and didn’t say anything about the matter, understandable considering that whatever uncomfortable sensation she had focused a lot on her womanly bits. I saw her very quickly trying to adjust her bra and blouse and seemed to be fidgeting a lot with her skirt for some reason.

The next day, she continued with the discomfort, still not saying anything about it but what was going on was a lot more obvious now. I’m mentioning this because it’s relevant, not because I’m a pervert! Anyways, I glanced at her modest bosom and it was definitely bigger now, her breasts becoming more prominent even with the modest clothes she wore. Her already thick thighs had thickened even further, being quite impressed as I already considered them to be top-tier.

The nerd’s movement throughout the day also became more awkward, she seemed to try very hard to conceal her expanded curves, her embarrassment being notable as she was constantly blushing whenever anyone talked to her. I wasn’t really concerned at all by this point, attributing all this to hormones, a little growth spurt and other mundane things; however, things quickly got much stranger.

The next day, I noticed that yet again, Sarah looked much thicker. Her boobs had grown yet another cup, causing her to express even more discomfort as she fought her bra, her hips were much wider, causing her skirt to cover less of her squishy thighs and her ass was a lot more prominent, the silhouette of her expanded cheeks starting to show through her skirt.

Appearance-wise, it was very obvious that this was not a regular growth spurt or anything hormonal, this was abnormal. What made things truly concerning though was her lowered ability to focus and general disinterest in the class. Knowing well the massive nerd that she was, I knew something was wrong with Sarah.

I approached her during the lunch break, asking directly if something was wrong or if she needed help. My friend just shrugged off all of these observations, jokingly calling me a pervert for noticing her bouncier curves and she explained her behavior from earlier as just her being exhausted. These explanations were kind of reasonable, but I was certain there was way more to it, having no clue if she was genuinely unaware or if she was hiding something from me.

My investigation continued throughout the next week, noticing how rapidly her tits were growing to porn star levels of huge, her usual skirt now looking insanely slutty as a light breeze was more than enough to reveal her inflated buttocks and her panties. From those brief up skirts, I could even tell that she was embracing that sluttiness as she went from having safety shorts on to now having a string bikini that barely covered her most private bits.

My friend’s behavior only grew more concerning as well, losing even more interest in the classes and talking more frequently about cute boys, her type and all that. This was something that she would usually be super shy to talk about, her face would become a tomato from blushing so hard and yet here she was talking about men very casually, more akin to the dumb cock-sucking cheerleaders she frequently mocked for their lack of intelligence.

Speaking of intelligence, that was another huge factor, one that made me realize that all this may have to do with that experimental liquid she had created. Her speech was very strange, becoming more incoherent, any questions she would respond with certainty about complex topics was met with a lot of ‘hmmm’, accompanied with her fidgeting with her hair and placing her finger on her lips that were also much thicker.

I also noticed she was putting a lot more effort into her makeup, something I would be happy for her to do, but seeing her go from the nerdy girl who didn’t care at all about her looks to now being irresponsible with her studies while putting a ton of effort into makeup was highly concerning.

Throughout these last two weeks, I confronted her about everything multiple times, from her abnormal expansion to her seemingly deteriorating intelligence. I kept getting increasingly more frustrated as Sarah didn’t seem to care at all about these concerns! I was very blunt about them too, and even then, she shrugged it off, saying that I was being silly and that I should just appreciate her becoming eye candy and even offering me to fuck her, not being concerned at all!

Sarah’s curves are still expanding. Today, she’s teh bustiest she has ever been! Her modest breasts, comparable to small stress balls were now larger than ripe watermelons, bouncy and jiggly like jelly, and from what she has told me, heavier than bowling balls. I have no clue how her back hasn’t snapped in half with such monstrous mammaries!

Although her giant boobs had far outshone her lower half, it was still very impressive. Her ass cheeks were like built-in cushions for her, her hips made her look as if she had experienced giving birth and her meaty thighs were as thick as tree trunks, all while simultaneously being softer and more jiggly than ever before!

Her behavior had only worsened too, aside from her literally undressing right in front of me and wanting me to fuck her massive tits, she also hanged out with those dumbass women that, again, she previously mocked. Her grades had fallen off a cliff and she didn’t care at all, a complete one-eighty compared to her previous self where a B grade would’ve made her stressed and anxious, now she just giggled like dumb bimbo whenever she saw a D and even occasional F grades.

Right now, I have no clue what to do to revert what happened to Sarah. She’s enjoying her new hourglass body and seems like she wasn’t missing being the cute shy nerd she was prior, but as her friend, I felt the need to do something about this! I had no clue if she was going to get dumber and curvier, but I had to find or do something ASAP!
