Hearing my sentence, which she didn't seem to expect at all, a blank look appeared on her face, followed by a look of confusion.
"W-What do you mean by that? I don't understand." She looked at me weirdly.
"Do you really not understand?" I asked and held up two fingers.
"What is supposed to be two..." I added two more fingers, and held up four fingers in front of her, and said
"...Is actually four."
She still didn't seem to understand what I was saying. But the moment I glanced at her chest as I held up four fingers, her grey eyes immediately widened in shock, and her mouth parted open.
She looked at me with utter belief. And as her face slowly turned red, she covered her chest, like she was protecting a treasure from me.
But this time, she was moving her hand around all over her chest, as if she wanted to cover every inch of her breasts, which was obviously not possible.
"Y-You...You really know about it?"
Astrid said with a look of incredulity on her face while placing her hands back down on her lap, understanding that no matter how she hid her chest, her secret was already exposed in front of me, and decided to accept her fate.
"Didn't I already say so earlier?"
"I thought you were joking at that time. I didn't think you would actually know about something that I've kept a secret my whole life." She said in a daze.
She then looked at me and asked in a confused manner
"How did you find out?...Did you already know before I met you, or did you just find out?"
"Well, my suspicions started when I first met you, and they started to grow even more fervent, as I interacted with you along the way.. But the moment that really made me confirm the truth was when I slapped your chest."
"That feeling in my hand at that time...What should I say...It just wasn't right..."
I looked at my hand as I contemplated that feeling.
"Pervert! Stop rubbing your hand like that!"
She exclaimed and grabbed my hand to stop me from trying to remember that softness I felt. She then looked at me and asked
"Why did you even feel suspicious about it? I wore multiple layers of clothes, including my labcoat, just to cover up anything that could give it away."
"It's exactly because you wore so many layers that I wondered why you would do such a thing, when it isn't even that hot out...And then I noticed that the area wasn't adding up to the actual size, and made me wonder if what I was theorising was actually true."
"The area wasn't adding up to the size..." She repeated those words and then glared at me and asked
"Luca, you hooligan! How closely were you looking at me, that you could even find out that out?!"
"I'd rather not disclose that information." I coughed and ignored her question, which made her harumph.
"There was also the factor of the overwhelming elasticity they had and the feeling as if I touched a valley instead of a mountain when I slapped them, which were dead giveaways."
"Stop deducing it, like it's some kind of crime scene!" Astrid cried out in embarrassment.
She then glanced at me with a shy look on her face and asked in a low voice
"D-Do you really not find them weird?"
I shook my head.
"Do you actually find them appealing in your eyes?"
I nodded my head, which made her blush.
"Then, just like what you've said about the rest of me, what do you find so attractive about them?"
She asked, looking at me with expectant eyes, which made me reply, saying
"Do you know maths? Multiplication in general."
"Of course I do! It'd be a joke if a member of the 'Industrial Bioprocess club' didn't know basic mathematics!"
She proudly said, as she boasted the name of the club she belonged to, which seemed very important.
"Then, can you tell me a dish you really enjoy?"
"Beef Sirloin Steak!" She immediately said.
Beef? She likes beef when she's part cow herself?
Would she start chewing on her leg if she ever got a little too hungry?
It can't be, right?...Right?
"Then, can you tell me how many plates of steak there would be if one plate of steak was multiplied by two?" I ignored Astrid's cannibalistic nature and continued my explanation.
"Two Beef Sirloin Steaks!" She shouted excitedly, as if she were proud that she answered the question, even though it was the most basic question.
"Then how many steaks would be there if we multiplied those two plates of steak with two?"
"Four Beef Sirloin Steaks!"
"Now, if I've given you the option of me treating you to either two steaks or four steaks, then what would you choose?"
"You're going to treat me to steak?!" Her eyes lit up, and her tail moved left and right in an excited manner.
"No, I'm not. I'm just-...N-Never mind, I'll treat you to some steak later." I immediately changed what I was going to say when I saw the dejected look on her face when I was going to deny her treat.
"Really?! Then you have to treat me to the one in the cafeteria. The steaks taste amazing there!"
"Fine. But before that, answer the question I asked."
"Of course, it's the four steaks. Why would anyone choose the lesser option?" She said as if it were obvious.
"That's the same way I feel about your 'insecurity'."
I said, as I looked at her with a cheeky smile.
"I already love them as they are. So it's only logical that I would love them even more if they doubled...It's simple maths."
"You lecher!...Don't use the sacred subject of mathematics to explain something so obscene!"
She blushed and tried to headbutt me. But I quickly stood up, and took a step away from where she was sitting.
"Do you think you can simply run away, after blasphemizing math in such a vulgar way!?"
She said, as if she was really offended that I used math for such a crude matter, and got up to chase me.
But before she could lift her other leg, she felt her legs go weak and she sat back down.
"What's wrong?" I went closer and asked, wondering if she got injured when she was the one who thrashed me around earlier,
"I can't really lift my legs...It must be because I've been sitting for so long in that awkward position, right after that exhausting session of throwing you around, like a volleyball."
She looked at me and grinned, as if she was using the beating I got earlier as a way to make up what I said about math.
My face twitched, and I really wanted to slap her breasts once again, seeing that she was acting so haughty when she was still on the ground, looking up at me.
But it also made me sigh in relief, that she seemed to accept that I find her attractive, unlike before.
Now, I do wonder if I have to go through this entire process of explaining why I find a demi-girl attractive to all the girls I meet in the future.
It seems like a tedious task to make sure that I really do find them attractive in my eyes, which I hope I don't have to do too often in the future. And I hope they won't start to argue with me when I say I find them attractive, like Astrid did.
