"MARRY ME!" he asked with joy.
Sister Lily closed her eyes in annoyance.
*WHAT? I haven't seen him in months and this is the FIRST thing he asks me? When is he going to understand that no means no?*
"Asta, listen, you know very well that..." said Sister Lily by turning around but she was cut off when she saw the boy she had taken in a while ago. The little boy had changed, changed a lot. She didn't imagine for a moment that it was that much. if his head had not changed much, his body on the other hand it was quite another story! He was muscular, and not just a little bit, he was EXTREMELY muscular, his clothes looked even too small! Sister Lily was disconcerted, it was really him? The little Asta? He seemed so different, so...
"A-Asta? W-W-What the...?" she stuttered. She was doubly surprised by the fact of seeing him here but also by his change. For some unknown reason, she was shaking and also getting hotter and hotter.
*What happened to you Lily? It's Asta, the same one you knew but... but how could he change so much? And why am I suddenly hot? why does my heart beat so fast? Lily, don't tell me you're attracted to him? He's just a teenager but... but... my god, he doesn't look like a teenager anymore! ... No Lily! Pull yourself together, for God's sake! It's Asta, you can't be attracted to him, you're a nun but... but he is so... so...*
Asta noticed Sister Lily was panting faster and faster and seemed to tremble. and then she was sweating too... she was not well, that was for sure!
"Sister? Are you sure you're okay?" asked Asta, worried.
"Asta... I... I..." panted Sister Lily having more and more difficulty to contain herself.
*What happens to her? Is she sick?* he thought. "Sister, what is happening to you? Are you sick?" he asked.
*Lily! You have no right to fantasize about him, you are a nun! But damn, I can't help it, he is so... so...*
Asta posed his hands on Sister Lily's shoulders.
*Oh my god! Calm down Lily, for God's sake calm down!!!*
Asta moved his hand on her chest.
*Holy crap, her heart beat so fast! And her skin is so hot. Really, what's going on with her? It's not her normal state ... Wait! To be warm, the heart beats fast... it seems to me that this is what we feels like to be... in love? What? Is Sister in love with me?* Asta thought.
Asta calmly took her arm and brought it to his chest. Sister Lily began to moan louder.
*God damn Lily! You should be angry by what he is doing then why do you feel more and more horny about him?*
Asta smiled. Yes, she seemed to enjoy it!
*You like it, right?* asked Asta. He took Sister Lily's hand again and slowly lowered it, caressing his pecs and passing over his incredible muscle brick wall. Again, Sister Lily moaned louder.
"P-p-please Asta! S-s-stop it!" she said.
But he had no intention of stopping, especially not now that he could see that Sister Lily appreciated more and more. Besides, he too was very hot and his heart was racing too and... what? Asta was surprised when he felt his muscles automatically flex.
*I didn't know that being in love did that also* he thought, astonished by the situation.
But the contraction continued to intensify and his body began to boil.
*What the hell? My muscles? T-They are growing again? But... I didn't take any other pills though? What is happening? ... OH GOD! It's fucking intense!*
His face began to tense up and he started to make little grunts.
From her side, Sister Lily felt Asta's abs flexing and she was amazed by their hardness.
*Oh my god, they are so hard! And so big and ripped and... what?*
Sister Lily noticed that it seemed to "move" under the shirt! She felt once again and and it was as if Asta's muscles were... growing??? It was then that she noticed that he was extremely tense, his face became more and more red and his veins were exorbitant.
"A-Asta? A-Are you okay?" asked Sister Lily but on Asta's side, no, it really wasn't okay.
*D-D-Damn! It's getting un-unbearable! W-Why is it so intense? And... ??? FUCK! It's still increasing! How is it possible? I didn't swallow any other pills though? Shit... SHIT! OH GOD! I can't hold on much longer like this!!!*
"GGGNNNNNNNHHHHH!!!!!" moaned painfully Asta.
Sister Lily didn't understand what was happening, especially since she noticed something that disturbed her: Asta seemed to be getting growing, getting more muscular... no, he didn't SEEM to be: he WAS really getting more muscular! She could see his clothes stretching, he was also becoming taller, which made his shirt too small, revealing an incredible pair of abs. But how was it possible? Growing like that, It's pure magic but... Asta doesn't have any so how is it possible?
"ASTA? ANSWER ME!" shouted Sister Lily, worried but also stunned by the amazing show.
Suddenly, Asta eyes widened. Like a volcano, he felt an internal pressure surge: he was about to "erupt".
*Oh god! I can't hold on, I can't hold on anymore! Oh god! OH GOD! OH MY FUCKING GOD! I'M GOING TO EXPLODE!!!*
There was a second of silence and then...
"AAAAAAAAAAAAAAARRRRRRRRRRRRRGGGGGGGGGGGGGHHHHHHHHHHHHHH!!!!!!!" yelled Asta.
His whole body exploded in muscle: his traps engulfed his neck even more, his shoulders became cannonballs, his biceps became enormous, gaining several inches, his pecs were so big, his abs exploded and looked like six huge boulders implanted under his skin, quads became so big that his pants tore in many places, the same thing had happened to his shirt which was covered with tears, no longer able to contain his muscle mass. He was also taller, reaching a height of 5 feet 7 and surpassing Sister Lily.
And it was over. Asta was here, panting, trying to recover after his incredible muscle growth.
*God! I don't know what just happened or why I grew again but... I FUCKING LOVE IT!!!* smiled Asta.
Sister Lily had her eyes and mouth wide open. She couldn't believe her eyes. Asta was hot before, but now... now he was as hot as lava!!! She could not contain herself at all, it was much too hot. May god forgive her...
Asta looked Sister Lily and notices the extreme state of excitement in which she was. He smiled broadly.
*Hehehe, in the end, maybe this muscle growth came at the right time. I think it's time to ask her again!* he thought.
"Well Sister, do you want to marry me?" asked Asta, in a deeper voice than before.
