That's not skin. Thats a skin colored fabric that covers the crotch. Have you ever seen a girl in panty hose? Have you ever seen a girl without her calling the cops?
She is already wearing pantyhose. And unless this other material is super thick, you would see her pussy through the fabric. And they don't make fabric that looks that much like skin. Even if that was fabric, look at her ass. You can see the shadow between her cheeks. If she was wearing skin-colored pantyhose that could cover up her pussy, you wouldn't see that shadow either.
