Kapitel 27: Booty Physics

"My butt? Kafi, you think that my butt is too fat?" My mother asked me as she looked back at me and then at her butt, like she was wondering if her behind was really fat, as I said.

"Of course it is. You're even proving my point right now when you're trying to look back at your behind, since whenever you try to do so, your ass jiggles like it's made out of jelly." I said, which made my mother realise that what I was saying was true, since she could see her plump butt move around with her own eyes, when she turned around to check.

She was embarrassed that her butt was making such obnoxious movements right in front of her son's way, and tried to turn around and cover her butt. But I didn't allow her to do so, and firmly grabbed her by the waist and held her in her place.

"Where do you think you're going, mom? I haven't even shown you why I stopped you from jumping on my lap, and the true power of your ass." I said as I moved my hands down her waist and grabbed her butt cheeks.

"What power?! My butt may be big, but it definitely doesn't have any power like you said!" My mother cried out with a flustered expression on her face, like she had no clue about the power I was talking about.

She was also completely helpless and couldn't cover her butt like she wanted to, since her behind was caught by me, and she couldn't do anything else other than let her son explain why her ass was so dangerous.

"You want to know your ass's true power, mom?...Then, just look at this." I said, and then gave a light slap to the side of my mother's right butt cheek.

Pa~

"Ahh~"

The slap was relatively soft and wasn't anything that could actually hurt my mom, but she still let out a suggestive sound upon impact. But what was important was not the sound she gave, but the way her butt was reacting to my slap.

Even though it was a light slap that barely had any force behind it, it was still enough to send waves through the rest of her butt cheek. From the starting point on the side of impact, it created rippled of flesh, like the ones you would see when you throw a rock into a pond and travelled all over her mound of flesh.

And not only did the waves move through one cheek, they also hit her other cheek and transmitted their force, which made the cheek jiggle like pudding as well. Even though I didn't even touch her opposite cheek, and only slapped one side, the elasticity of her butt was more than enough to send the bound energy to the other side. Honestly, with such a display of physics, it would be a perfect way of explaining kinetic energy and momentum to students, and would make every single student out there ace their physics exams.

My mother also saw this wonderful spontaneous reaction that was happening behind her and covered her face in embarrassment.

"See mom. Do you see the power your butt possess? Do you understand why I'm calling it fat and something that could break the chair?"

"That's not fair, Kafi! I'll agree that it is indeed a bit big, but there's no way it can destroy a chair!" My mom argued back and fought for her butt's reputation.

"You don't understand the elastic power of your butt, mom." I tried to make her understand. "If just a small slap like that can send waves throughout your entire butt, then just imagine what would happen if I gave you a firm slap that would leave a handprint on skin...It would probably create a tsunami of fat, that would carry devastating force with it!"

I acted as if my mother's butt was a weapon of mass destruction; that could not be underestimated, and I made her even more ashamed of having such a big butt.

"And just imagine what would happen if you jumped on top of my lap with this meaty ass of yours. You're weight, along with your butt's elasticity, would probably send a massive rebound force towards me and send me flying." I said in an exaggerated manner.

"Nooo~ There's no way that can be true~"

"But it is true." I reminded. "Even if I can somehow handle that rebound force at the cost of breaking a few bones, this poor chair wouldn't and would probably be smashed into pieces because it couldn't handle how fat your behind is."

"Stop it, Kafi! Stop talking about your mother's butt like it's a weapon!" She cried out with a flushed face, and wiggled her butt that was in my hands in retaliation.

"Fine. Then, instead of telling you how your ass could potentially destroy the chair, let me tell you about how the chair is harming your ass." I decided to change the topic since she was adamant that her butt wasn't lethal, even though it was, because of how bouncy and elastic it was.

"The chair is harming me? What do you mean by that, Kafi?" My mom asked, confused about what I was talking about.

"It's true. To prove that it's harming you, let me ask you a question." I looked at the chair she was sitting on. "Does your butt not sting every once in a while, especially along the sides?"

"...It does...It actually does! How did you know that, Kafi?" My mom thought for a moment and answered, and then looked at me in wonder at how I found out when she never mentioned it to me.

"It's easy. You'll understand once you sit back in your chair." I gestured towards her wooden dining table chair.

She didn't seem to get what I meant, so she sat back on her chair to find out herself. But even after she sat down, she couldn't notice any changes.

After seeing that she couldn't find the cause of her pain herself, she looked at me to explain it for her. I simply nudged my chair towards her and said

"This. Look at this. This is what has been causing you pain for a while now."

I first pointed towards the area near her butt, which was the cause of the pain. But since she didn't seem to understand what I was talking about, I directly grabbed onto the chunk of flesh from her buttocks that was sticking out of the chair when she sat down.

It was the excess fat that flooded from her seat's sides when she sat down, since the seat itself was too small for her butt, and she too let out a shriek when her butt's meat handles were suddenly grabbed.

"Hyaa!~"
