Ava, Hailey's younger sister

In the middle of the pack of cheerleaders is Ava, Hailey's younger sister.

Ava is gorgeous and similar to Hailey except shorter hair an thinner.

You knew Ava had a crush on you for years, and you must admit that you had caught her in a bikini on a few occasions while she swam in your backyard pool.

That same girl was now staring right at your exposed member. She wasn't laughing, not even smiling. She just sat their with a shocked look on her face. Your eyes then meet and that's when you see her start to giggle under her breath.

Again, you realize that you haven't moved even to cover yourself, you push your hand down on your crotch to cover everything. This send the cheerleaders into a hysterical laughing fit.

Not knowing what to do next, you do the only thing that comes to your mind.

"IT GETS BIGGER, I SWEAR!!!" you yell to the group staring down at you.

"Yeah, maybe to the size of a 7 year old", the black haired cheerleader yells back.

This sends the group into another laughing fit.

You have to do something to get out of this situation, but what?
