Prove it isn't small

One of two stories I posted on Reddit, posted here to keep in one place, mostly fictional but based on true events! 

A group of us all aged around fifteen were hanging out after school, there were 8 of us, 4 boys and 4 girls. They boys were messing around and one of them pulled my shorts down revealing my penis to one of the girls, I quickly pulled them back up and looked at the girl but she had looked away so I thought she didn't notice. Later that evening the eight of us, along with two other girls were on a group chat online.

Amy: Oh and Scott pulled down Steven's shorts and Isla saw his willy!!!!!

Taylor: Omg! what was it like?

Isla: 8D

Everyone replied with numerous laughing faces.

Me: It's not that small, you must have not seen it right!

Emily: Yeah right, that's what they all say.

Damien: You'll just have to get it out and give her a proper look next time.

Isla: Ew no thanks.

We moved on from this eventually. A few days later I was hanging out with Emily and Amy when Taylor and Isla approached, I didn't look Isla in the eye, truth was I was a bit mad at her.

Isla: You still annoyed cause I seen your little willy?

Me: It's not little, stop telling people that!

Isla: Okay, okay, fine you have a massive dick, happy now?

I gave her a fairly sarcastic smile and we all sat in silence for a few seconds.

Taylor: You know... You could just show us?

Me: I'm not getting my cock out for you.

Emily: How about this though, if it's big, like you say it is. We'll go around telling everyone you're hung like a horse. If it's small like Isla says it is, we'll keep it to ourselves and never talk about it again.

Me: No way.

Isla: Cause it's smalllll

Me: It's not small!

Amy: So why can't you prove it? Just a quick look.

Isla: Give it up girls, he's not going to show you it cause its soooooo little!

Me: Oh for fuck sake Isla just let it go.

Isla: No you're basically calling me a liar.

Amy: Oh this is taking too long, Emily, Isla, grab his arms.

Emily and Isla quickly grabbed my arms as I was taking by surprise, Amy then sat on my chest so that I was pinned down and Taylor quickly move on to my legs. I shouted at all of them to let go of me. Next thing I knew I felt Amy start to undo my belt and pull down my zipper. She then pulled down the front of my boxers to reveal my penis to the girls. They immediately started giggling.

Amy: Well looks like Isla was right, it is tiny!

Taylor: Yeah it's really, really small, I'm surprised Isla even managed to see it!

Isla: You see I wasn't lying, it is really small!

Emily: There isn't even like a shaft, it's just balls and head!

Me: Get off me!

Amy: Nope, we aren't done inspecting your TINY little willy!

Emily: Yeah we need to confirm just how TINY it is.

Taylor: I think it's the TINIEST little penis in the world.

Isla: Maybe it's so TINY cause you keep lying about everything!

Me: It's not that small, it gets bigger!

Isla: If you say so baby dick. None of us are touching that to make it bigger.

Taylor: I'm just gonna snap a few pics of this little thing...

Me: No! You said you would keep it to yourselves.

Amy: You didn't agree to that!

Once Taylor had taken her picture and the girls had laughed a little longer they got off me and I quickly fixed my trousers back up. I started to beg Taylor not to show anyone the pictures.

Taylor: Here's the deal little dick, you are never to be mean to Isla or any of us ever again and we'll keep this to ourselves. So behave yourself or this goes viral, got it?

I nodded sadly.

Isla: You know, I have a better idea. How about this... Get it out again, just one more time... And we all get to kick you in your tiny naked balls then we'll delete the picture.

Me: No way! You can't kick me in the balls four times!

Amy: How about just once then? Me: I... I guess so.

Taylor: I vote Isla does it, she deserves it.

The other girls agreed and I started to undo my trousers again, Amy yanked my trousers and boxers all the way to the floor and then pulled my shirt up a little so there was no where to hide. They all started to laugh again.

Taylor: I just can't believe how small it is!

Emily: I'm pretty sure my dog has a bigger willy!

Amy: I'm pretty sure my three year old brother does too!

Isla: It's such a small target, hope I don't miss.

Amy and Taylor held me still and I shut my eyes bracing for the impact, I felt the sharp pain immediately as Isla crashed her foot into my balls, my legs crumbled beneath me and the girls let me fall to the floor. They all laughed loudly. They then left me lying on the ground still exposed.

Emily: Oh and by the way original deal still stands, you're nothing but nice to all of us or everyone gets to see this nice video of Isla kicking you in your tiny little balls! See ya!
