Koharu's summer 7

The next day,  even though it wasn't a school day, Koharu and Hanako decided to meet up at school.

They planned to go to the beach and then a nearby hot spring, but,for some reason, Koharu was once again wearing her gym clothes.

“Eh? Why are you wearing that tracksuit again?? You are not planning on going to the beach like that, right???”
Hanako asked her, but even with Koharu’s body covered with the tracksuit, the difference since last time, even just the previous day, was evident.
On her body the fabric was tighter, showing the bigger and bulging muscles under it.

With the unmistakable smile on her face, she pushed more. “Come on, I’ve been cheering for you so much and now you don’t want to show me your progresses? This makes me sad~”

Koharu started to blush “B-But… Was really excited with my progress, but then this morning all the clothes I tried to put on were so tight they started to rip… Then I realized how embarrassing and indecent it would be to go around like that…’

Taking advantage of Koharu’s embarrassment and distraction, in a quick move, Hanako partially pulled down her tracksuit. 

Koharu’s increased muscle mass made the fabric so skin tight that she could only expose one arm, but was quite enough to show the impressive transformation her body undergo in such a short time.

The size of her arm was diminishing to just define impressive. Its circumference was now the same, maybe more, than one of Koharu's thighs were in the not so far past, with a huge vein going through all the arm, continuing in her body.

“Oh my…” Hanako started at the pure muscle mass in front of her.
“Can I touch it?”
Too embarrassed to reply, Koharu just nodded.

Then Hanako’s hand started to get closer to the arm the closer it got the more it looked like a child’s hand next to It.

She finally reached the arm and with an amazed, yet excited, look she started to caress and feel It. Once the contact was made, Koharu's body jolted.

“Incredible! It’s so big, warm and… hard~. So, that’s what happens when you Flex your muscles?”

Koharu became even redder and quietly replied.”Actually… I’m not flexing It…
Because…that’s what happens when I do that…”

Suddenly Hanako felt Koharu’s arm moving and then twitching.

With her hand still on her bicep, it suddenly became even warmer and started to increase even more in size. The vein on it became even wider, bulging over the arm.
Soon stretching noises started to come from the track suit’s fabric which was only partially covering that side of her body.
The stretching noises then transformed into ripping noises as the tracksuit partially gave up on covering her.

Koharu’s face was now so red that felt smoke could come out from her ears at any moment.

“I knew it…! Now I don't have anything to cover me anymore… So embarrassing and indecent!!!” 

Hanako looked pretty amused by the situation, but visibly turned on too.

“I think you shouldn’t hide anything. Is normal for a girl to show some skin and his strong points. And yours are… very strong~

So you can proudly show everyone the result of your hard work!

Now, no more time wasting and let’s go to the beach!”

“O-Ok!” After those works Koharu looked more reassured and confident.

Finally at the beach, Koharu could show her newest swimsuit. Since the first she got not long ago, she had to change and adjust the size to her increasing body multiple times, costing her a little fortune.

But, now she could show her entire body in her muscular glory!

And now Hanako could finally see Koharu’s body in its completeness since she saw her muscles for the first time.
It was already obvious, but now the complete transformation was clear as the sun and the difference in the Koharu she saw just a few weeks ago was incredible.
The size of her muscle mass increased more than just a couple of times, so much to make that already well muscular Koharu think compared to the present one.

“Oh my~ Can’t say I wasn’t expecting it, but you are really huge! Look, everyone is turning around and staring you, you became like the beach queen~”

Realizing that from Hanako’s words, Koharu started to blush and cover, like it was possible, her body.

“Come on, don’t be shy, there is nothing to be ashamed of! Everyone just love what they see~
If you listen, you can hear it~”

From the various people passing and watching could be heard some talking to each other on how sexy and cool she looked.

“See? They just love what they see, and the same is for me!
I have an idea, what do you think about flexing those guns just for a moment to show them in their glory~?”

“E-Eh?? Here? In front of all these people?? It’s too embarrassing!”
Koharu looked around, but all she could see was the excitement in people’s eyes, especially in Hanako’s, even though that was probably a different kind of excitement.

After a few moments of reluctance, she finally was convinced. “O-Ok… just for a moment…”

So, she started to raise her already big arms, and started to flex both. In a moment her biceps bulged, increasing in size, with the veins surrounding them getting even thicker.

Gasps of surprise and incredulity surrounded all the area. Various exclamations like “I would love to touch them” or “I wish I could be so strong too!” could be heard all around her.

Hearing all those compliments, she slowly started to gain confidence, and soon she started to smile.
After a bit that smile became even more confident, and, with that, she suddenly started to flex her arms even more.
For a brief moment, everyone had the impression her body suddenly grew. Her arms looked bigger, but not only them, all her body looked wider and her swimsuit tighter.

But soon she stopped her pose. And the people slowly scattered around the beach continuing her day.

“(What was that? For a moment, with everyone looking at me so excited, I felt stronger, more powerful… Maybe was just my impression…)”
Ignoring her strange feeling, Koharu continued her day at the beach with Hanako.

While writing more and more ideas continue to came in my mind, becoming this long part.
