Kazusa's heat control, day 3

Yesterday you made Kazusa promise to not leave school early and that will be you to meet her and than go home together.

But when you arrive you found only the rest of the After School Sweets Club without any trace of Kazusa.

So, when you asked them they told you she went to the Trinity's gym.
This was quite unexpected for you, especially since you didn't even knew a rich leadies school like Trinity had a gym.

Than you went to this gym, which was, as expected, pretty empty. That's why didn't took you long to find Kazusa.

But, after few steps you stopped.
You started to stare at her speechless. Not because she was lifting those weights with what looked an incredible ease, but because you immediately noticed that in that short time her body changed again.
While she was too absorbed in her training to notice your arrive, you couldn't stop to stare her.

She has already been a very pretty girl, but now she looked even more a work of beauty.
Her body, from just fit, became more muscular.  You could see the muscles in her body have grown enough to became visible, with the shape her biceps very clear, thanks to the training too.
The abs, which yesterday were slightly visible, now were a well defined six-pack, with obliques starting to develop.


After not so long she finally noticed you.

"Ah, Sensei, why are you here?"

| Well, I came to pick you up, but you weren't with the other girls of the club.   |

"Ah! Sorry, Sensei!
Is that today I woke up feeling like a big amount of energy.
But, in exchange, my heat instinct seemed a bit weaker.

I managed to resist during the classes, but when the other girls noticed and touched my abs I almost lost control, so I tought wss a good idea to unload this energy in the gym.

Seems it worked tho, since I started to do exercises I had nothing else in mind."

Soon she noticed you staring at her body.

!Sensei? Why are you staring at my body so much?

Ah... You noticed my muscles grew? 

So, as I thought is pretty evident afterall... It's gross when a girl became more muscular, right?"

But you stopped her.

___________________________________________
| No, no!  Isn't anything like that...                                         |
|Actually... They looks great on you, you're really pretty.  |
|___________________________________________|

Hearing those words, she started to blush and all the resistance to her instincts she had crumbled and could barely resist anymore.

"S-Sensei... If you talk like that... I can't..."


Undertanding the situation you made her change to her normal clothes and took her home.



As soon as you arrived home she immediately took off her clothes sitting on the bed.

"Than, Sensei... quick..."


______________________________________________________________________ 
| Whoa, wait a moment, I still have to put away my bag and the other stuff, I'll return soon  | |______________________________________________________________________|

"Ok..."


When you returned, you didn't had the time to open the door that she was behind it, waiting like a cat.

But, probably at her limit, she tossed you on the ground.

"So, now we can do it right?"

______________
| Eh? This isn't...  |
|_____________|

But you hadn't the time to finish that she was already on top on you.
So without any other option, the two of you did sex on the floor.


You noticed that today Kazusa was more aggressive and took more the initiative.
Meybe something was really changing, not only physically.


After the sex on the floor your back hurt for a while.
