You decided to wait, wanting to meet her face to face instead. (And not get accidentally crushed if you did shrunk and she didn't know.)

Hours passed...

There was a knock on the door, when you open it, a very tall girl, shadows over you.

A mohawk cut with ring piercing on her nose, two ball piercing in her ears. A shark like tooth, and a skimpy red camo  nipple patch mixed with a harness on her chest. She's merely covering it with a thin layer of a worn out t-shirt with many holes here and there. 

She stretched down trying to get to your eye level, all the while stretching out the already worn out red camo booty shorts, while her fishnet legging stretched the thighs movement as her combat boots takes a step front.

Wow, you could see her well toned abs, fully clear from here. And with how beefy her arms is as it leans on the door, must be working out often at the Gym.

"Huh, you're shorter than you look. Meh whateves'. So, you got the money?" She showed her fangs at you with a smile.

You hand her the $20.

"Sweet!" Her face perks up, "So, got a place in mind, or do you wanna raw dog it here?"

About that, you wanted to ask her if she's cool with a secret you have, a little... Uh, trick he wanted to show you. 

"Hey, your paying. I'll wait."

As you closed the door while leaving it unlock, you took a deep breath, ready yourself as your heart beats quite fast at the recent events.

You hope this goes well.

You took out your shrink-ray, and began shrinking yourself. Thankfully the green hue isn't too intense. Now your sitting on a closed toilet, hoping you could still call her despite your newly small stature.

You yelled at her to come in. When she did, her eyes widen with shock. 

"W-what the?! Huh? Where did you go?!" She looks around, confused. You chuckled a bit from her expression.

You yelled at her, holding your amusing face, to check on top of the toilet cover.

She leans in on your spot, with a face twice as larger than before. You heart beats in fear for a moment at how sudden that was.

"Holy shit. How'd you do this?"

For a moment you decide to keep it to yourself, not wanting to get your shrink-ray to be revealed just yet. Instead you told her it s because of magic, oohhh

"Man that's so cool!" She smiles wide, 

With how intimidating her looks are, it... Sorts of makes you worry, she's not gonna exploit you now that your small... Right?
