Kazusa's heat control, day 5

The next day was a day off from school so you thought you would find Kazusa hanging out with the others, but they told you she went to the gym hours ago and they still haven't saw her since than.

You went to check and she was indeed still there.
When you arrived she was facing the other side, and even if still a bit far away from you, was impossible to not see that her frame became even bigger. That back you admired just yesterday was way larger with the top she was wearing at the limit of it's stretchiness.
And wasn't that different for her pants, she was squatting with an impressive big barbell and the view of her butt while squatting didn't left room for imagination.

So, before you could get too excited, you approached her. But the view from the front wasn't less stimulating.

"Ah, Sensei, is already this late?"

"Stange? Ah! No no. Actually, today I'm feeling great. So, since was a day off, decided to use this time to push a bit more with the weights... (afterall, Sensei like it...)"

You couldn't hear the last part she murmured. But stiil, you could see today her training was way more intense of the past days. Her arms were huge, probably 2 times bigger than yesterday, with veins popping all around them.
Her abs were now a compelte brick wall, you had to resist to not touch them,

Her growth in the last day was impressive, probably connected to the her apparent mitigated heat.

"Sensei? You seems a bit distracted... and red too, could be that you like what you see?"
She flexed her arm a bit with a little smirk, she was starting the be a bit more pushy.

"Well, than... it's time to go I suppose"

This time she totally took the initiative, but you let her before yuo could do something inappropriate outside.


When you arrived, Kazusa seemed less impatient than the other times, such that she took a shower before doing anything. Another sign she wasn't just driven by heat and instinct.

She came back from the shower, with her muscles having a more relaxed look, but not less impressive.

But today she had a request that took you a bit off guard.

"Sensei... Yesterday was really fun and good when I took the initiative, so... today I would be the one making you feel good..."

Before you could say yes or no, she pinned you down and in no time she was on top.
Wasn't your intention to resist, but watching her seductive smile in that moment would have made it hard to do that.


And so, she started to move and for the first time you did sex with Kazusa totally on controll.

Her movement was a little "intense", probably her rapid growth made hard to her to controll her fast increasing strenght.




The cure indeed worked, but the growth part was "bigger" than you expected.
Two day still remained to the end of the cure circle, but probably I could be considered a success already.
But... for some reason you decided to continue until than.
You didn't wanted to admint, but deep inside you, you wanted to see how much bigger she could became.
