Alexis, another girl from your school

As Ashlyn hurries out of the store, you hear a voice near you mutter derisively, "The mouse is scared again. What a surprise." You look over and then quickly turn your face away so you don't get recognized. It's Alexis, another girl from your class, who couldn't be more different from Ashlyn. Tall and leggy with long blonde hair, Alexis doesn't hide her body. In fact, her tight clothes and midriff sometimes run afoul of your school's dress code. She's also got a handful of facial piercings, a belly button ring, and both of her nipples pierced. You haven't seen them, but most of the school knows; she shows them off at parties. Not that you get invited to parties.

She's still muttering about Ashlyn as she takes a few items into the dressing room pulls the curtain closed. "She probably saw her tummy in the mirror and had a panic attack. Little prude. I mean, jesus, it's the 21st century. It's just skin, girl. Everybody has it." True to her stated philosophy regarding skin, Alexis did a considerably less thorough job closing the curtain than Ashlyn did. She left a few inches open on one side, so you can stand a few feet away, pretending to browse a rack, and watch her change.

First she takes off her shirt, revealing a boring sports bra underneath. She tries on a few different shirts this way, and you start to worry that this is why she was so cavalier about the curtain - she shows more skin than this in the halls of your high school. But then you see her reaching for her waistband- and yes, down go her tight jeans! Miss It's-Just-Skin is bending over in front of you, taking off her pants, giving you a great view of her tight ass in her thong underwear! You reach down to adjust your boner and silently give her credit for walking the walk. She stands back up, checks out her ass in the mirror for a minute, and then proceeds to try on a pair of even tighter pants. She has to hop up and down to get her ass into them, and she has absolutely no idea that you're watching the whole thing.

Around this time you realize that you have a cell phone camera. You hurriedly pull it out and turn it to video, hold it mostly behind a shirt on a hangar, and turn it towards the dressing room in time to see her wiggle and jiggle her butt back out of the pants. You're focusing on the camera, making sure it's recording (it is) and that she's in frame and in focus, and you almost miss when she wraps her arms around her torso and grabs the bottom of her sports bra. You look up in time to see - with your own eyes - her sports bra pulled up over her head, pierced tits bouncing free.

They're beautiful. You've finally seen what basically everyone cool enough to go to the right parties has seen. Probably more - while you've heard of her flashing or going topless at parties, you've never heard of her prancing around in nothing but a thong. The sight you're seeing has probably been reserved only for her boyfriends, if that.

Wait, why is she still in her thong? She didn't put her pants back on.

Your question is soon answered when she pulls her next "outfit" into view - a ridiculously skimpy little one-piece nurse's outfit. Billed as a "costume," it is so slutty (and so poorly made) that you can't imagine anyone wears them anyplace besides the bedroom. Alexis contorts herself into it, lifting her long legs one at a time to step into the "skirt" part, and then pulls the halter-like top over her neck and makes sure it covers her nipples (which is not a guarantee). After successfully donning it, Alexis turns around, looking at it from all angles - and unknowingly giving you the same courtesy. It's a ridiculous garment, but she looks fucking hot in it.

So, that happened. You've seen more of Alexis, the school exhibitionist, than the cool kids have - and a lot more than she'd ever want you to see. And you have it on video. Do you keep a low profile, record her getting dressed, and leave her none the wiser? Or do you approach her?
