Cousin/friend kicks me

Since the previous incident [[link](https://www.reddit.com/r/BallbustingStories/s/33CbTuEK6G)], which was maybe 3-4 years ago, all of us have grown a lot. But Olivia, she has grown more as compared to me. Olivia was always taller than me, being around 5'10, and me being maybe an inch shorter than her. And Emily being around 5'8. Olivia also became much more stronger and with a slightly more than athletic/average body type, and you could easily compare the difference when you saw her photos from now and a couple of years ago.

I've been thinking to tell Olivia about my fetish. Cause if she could hurt me without knowing I like it, things would be much different when she knows. At least this is what I thought. However, I didn't have to do that for today.
The apartment I live in has an accessible terrace at the top floor, so you could just go there and spend some time. That's what me, Olivia and Emily decided to do. But as it was too cold, we just decided to stay in. We kinda spent the entire day messing around and chit chatting, having fun and discussing things.
There came a moment when Emily joked about my facial hair saying I looked like a bear as I have a lot of beard and cheek hair. To which I pointed out her non existent moustache jokingly. She did take it as a joke but guess who did not. Olivia replied out of nowhere saying "hey dont tease her or it won't be good for you". I defended myself saying "how is that even related? And why are you angry if Emily isn't. Plus I think she can talk for herself". I looked towards Emily during this sentence as she nodded agreeing silently to my statement.

The look on Olivia's face changed and she replied "don't you dare talk to me like that".
I realised this argument can be a good way to get busted by Olivia (which is what I wanted, to be fair), so I played along.

"Or what?" I asked sternly.
"Or... My leg teaches you how to talk to me, I'll kick you in the balls so hard you'll forget your own name" She said lifting her leg in the air, showing her hard shinbone and white feet, with her toes stretching out, pointing towards my balls.
It felt hot and sensational, and everything was going according to my plan. I just had to keep this going.
"Hah, you won't do that" I said
"What makes you think I won't?"
"Well... I just know. And even if you do, I don't think you'll be able to hurt me so badly"
"Oh you forgot when I kneed you in the balls that day? Who was on the ground crying and groaning like a baby huh?" She said mockingly
"Wait what?! When did this happen?" Emily shot up asking Olivia curiously
"Oh just a couple of years ago, bet he remembers the day very clearly" Olivia said smirking at me
"And how do I not know about this?" Emily asked
"Cause you were not home and dear Louis (my imaginary name) was soooo embarrassed to tell anyone about this humiliating incident. Am I right Louis?" Olivia said in a mocking tone
Emily laughed at the conversation, she found this sort of funny, obviously.
"Okay I was not prepared then" I tried to defend myself
"Oh so you are prepared now?" Olivia said again in a mocking tone
"Yes I am!"
"Alright then, you wanna test that yourself?"
"Okay loser" I got up challenging her.
"Wow you're so eager to be on the floor" Olivia said laughing and got up
Emily adjusted herself on the couch, watching us with her eyes wide open and smiling at me.

"Are you ready for this? Just so you know, I'm going to be kicking you in your balls and you have agreed to this" Olivia said sternly
"Go on I'm not scared of you" I replied back
"Alright, good luck"

That's all she said. I could see her taking her right leg back and swinging it towards my balls with full force. By the time I could process what happened, she had already kicked me with the part of her leg where the insole meets the shinbone. Before all of this happened, I thought I would be fine and that I could take her kick without a lot of pain, as I've had my fair share of getting hit in the balls numerous times.

I was wrong. The kick was so hard that it literally lifted me off the ground. This, was the worst kick or pain of my life. I couldn't take it at all. I just fell to the ground immediately clutching my balls and curled up. At some part I could see Emily wincing at my pain and laughing covering her mouth, also concerned at the same time, and Olivia mocking, imitating me.

The pain was so bad I just lost control of any thoughts or any environmental awareness. All I knew I was groaning and whimpering and praying that this pain would stop soon. I lost count of the time as well.

A few minutes or I don't know an eternity later, when I was back in my senses, I was able to see Emily sitting next to me on her knees, rubbing her hand on my back, trying to comfort me but also giggling at the same time. Olivia was sitting on the couch with her legs crossed and laughing at me, still saying things I could not comprehend. Emily asked me if I needed any help to get back on the couch, to which I just told her in a cracked voice to let me be on the ground for a while, and I'll get up once I'm comfortable.

The pain, which took forever to go, and was so intense I felt I would puke. Luckily I didn't. After I got up and sat on the couch, I asked Emily to get me some water and ice. She brought me the ice and tossed it, and also a bottle of water.
Drinking water and applying some ice made me feel better, but I knew I had to go to the bathroom to check on myself.
I got up somehow, still limping towards the bathroom like a penguin.
Olivia pointed at me laughing and said "see how he's walking. That's what happens when you try to challenge me"

I just went to the bathroom and was back in 5 minutes, ensuring everything was okay, just a bit swollen.

I came and sat down on the couch, just across from Olivia. She got up and went to the front and went
"Hey, because you don't know what you looked like on the ground, this is what we saw"
She then proceeded to imitate my actions, rolling on the floor, groaning, whimpering, squirming, clutching her imaginary balls, and both of them just laughed at it.
While I, I regretted the decision of getting kicked. What I realised was I should have told her not to go hard. Maybe the next time..
