Koharu's summer 4

Even after returning home, because of the shake she drank earlier, Koharu’s body continued to be way hotter than usual, even if it was the middle of the summer.
So hot that night she didn’t used her pajama to sleep and instead wore some of her lighter gym clothes.

That night her sleep was pretty agitated.
While sleeping, her body started to get even more hot, sweat started to show all around her body.
After a bit, a little pain could be seen on her sleeping face. While still sleeping, body subconsciously started to flex her muscles, which, once again like the previous afternoon, started to swell, with veins appearing on her arms.

The next morning she woke up feeling her muscle slightly sore. But she thought it was because of the previous day.

Once up, she could feel her clothes drenched in sweat.
“What happened? I never sweat so much while sleeping before… Was last night so hot?”
And, maybe because of her agitated sleep (or something else?) her shirt was visibly ripped in a few parts.

“Well… Lately I felt like sooner or later I should have changed them, since I had the feeling they started to fit a bit too tightly than before…

But… Isn’t time to think about that! I have to take a shower before going to school now!”

A bit later, Koharu finally arrived at school, but a bit late.
While she entered the classroom, something really stood. She was wearing her tracksuit jacket.


After the lessons, Hanako, curious about this unusual attire, approached Koharu.
“How unusual~ What happened to your uniform, Koharu-chan?”

At the question, Koharu was startled a bit.
“A-Ah… W-Well… Is that…”
Hanako continued to stare at her smiling.
“It’s that… This morning I noticed it was too small…
And when I forced myself to fit it, the sleeves tore apart…”


“Oh my…~” Hanako exclaimed. “Are you telling me that you already outgrew your uniform? The same one that looked oversized on you just not long ago??”

Red up to the ears, Koharu nodded.

“Amazing! So the little present I made to help you really worked~!”

“I suppose it is because of it…” Replied Koharu. “It’s true that lately I worked harder to increase my muscle mass, and it was slowly starting to pay off. But after drinking that, they suddenly grew that much…
An effect like this shouldn’t normally happen. What was that thing?!”

“Eh?? I noticed you wanted to buy some supplements for your training, so I just gave a good look at the magazine you were reading and bought some normal proteins/mass gainer mix at the black market~” Hanako replied with a smile.

“The black market?! But I heard that place is a dangerous and shady place! Are you sure this is safe?!!” Koharu started to look a bit worried.
“If you know where to go, the black market is a source of very interesting toys~” A more mischievous smile was now on Hanako’s face.
“They guaranteed me it’s 100% safe, even if it's a bit strong for a young girl (and we are starting to see what he meant), and it’s a unique product because of its rare ingredients. So we have been lucky to find it! And it’s working right?”

“But, don’t you think it is time to show those results? Come on, take that jacket off~”

Koharu started to panic.
“E-Eh? Here??
What if someone saw us?”


“Don’t worry, the other already left~”

“But… You really want to see that?
When this morning I suddenly saw my body this big, I got scared… Isn't it gross and unnatural for a girl to grow this muscular and so fast?”

Hanako looked at her with a more gentle smile this time.
“When the other day I told you that your body really looks great on you, I wasn't joking.
You know a muscular man is very attractive to many girls, right? But when I saw them on your body the other day, it was way better. The contrast between your cute face and those toned muscles, and the progress of your growth… Was really… exciting~ I had much fun the last few nights with just the memory of it~”
Suddenly her smile turned to her usual mischievous one. She suddenly grabbed Koharu’s jacket and unzipped it.


“Oh my~!”

Thanks to a partial resistance of Koharu, she only managed to expose her torso and an arm. But it was enough to see the difference from just a few days ago.

Her abs were deeper and bigger, and her torso looked a bit wider too.
What was visibly wider were her shoulders, with a perfect round shaped and muscular shoulder. Going down her shoulder, her arm was probably almost twice the size, with now the triceps and biceps very well distincted, with the last now showing a perfect round shape, making her wonder what its status while flexed could be.
A huge veins was traveling from her shoulder, down her bicep, continuing down her arm.

“D-Don’t look so much… It’s embarrassing…” Koharu tried to cover herself as much as she could.
She noticed Hanako’s excitement while watching her body, which looked genuine. And so, she asked her:
“D-Do you really like it? Doesn’t it look strange on someone like me?”

“I’m serious! They look great, I have never seen muscles so sexy before!
And seeing that it’s finally arrived Koharu-chan’s time to grow, I’m really moved~

But… It’s my impression or your chest looks a bit bigger~?”


“E-Eh?!?! Really??” Koharu immediately checked her chest area.
Maybe because of her pectorals muscles started to develop too, but inside her sports bra a way rounder shape than before could be seen.

“You’re right! They are not flat! I can definitely feel them rounder!” In a matter of seconds all Koharu’s fears and worries disappeared.

Hanako smiled at her enthusiasm and encouraged her.
“So, continue to do your best, can’t wait to see you grow more.
And take this, it is the mix I used to make you shake. Don’t forget to show me your progress. (even if I doubt it will be easy to hide them from now on~)” She passed a container to Koharu.


“Yes, I’ll work even harder!”

And so, Koharu rushed out of the classroom to go to the gym.

This could be the longer thing I have written in long time, if not ever lol
Because of my crappy english and writing skills took me two hours. And was so had to split the part in 2 too.
So, tomorrow, which I was making a rest day to have some relax time on the 15th August (holiday in italy), will post the other part instead.

So, I'm sorry if you will see the same content for 2 days, I always try to vary, but was an empty slot anyway lol
