Teach Natalie that beauty is only skin deep

A thumping from the wall caught Aaron's attention, and he knew what was coming next.

"Fuck off!" Natalie's muffled yell came through the wall. "Stop using the water!"

"I'm just washing my hands!" Emily's reply came from downstairs.

"Well fucking stop!"

"I've still got soap all over them, just give me ten seconds!"

"Fuck you, I'm in the middle of a shower!"

"Don't swear at me!" Emily said, sounding hurt. "You're always being mean to me!"

"Shut up!"

The bathroom door slammed shut and Aaron could hear Natalie cursing as she turned the shower back on.

Well, at least she'd saved him the trouble of finding a target. And this way, he wouldn't even have to feel guilty.

Aaron waited for her to finish her shower - she ran the water for well over sixty minutes - before opening his door to catch her in the hallway.

"What do you want?" she said, heading back to her room with a towel around her body and wrapped around her hair. "Stop perving on me, weirdo."

Aaron shrugged. "Nothing."

Aaron lay the skin out of his bed, feeling the fine, elastic texture of his sister's body between his fingers, the rubbery strength of her joints and the incredible softness of her pussy lips, before stripping completely naked himself.

He was just about to reach for Natalie's skin when he noticed something on the sheet of instructions. Depending on which way up the scissors were when used... well, silver side up clearly turned people into skins you could just wear. Gold side... shit, it looked like the skins remained alive and crawled around eating people.

Natalie's skin had been pretty limp when he'd picked her up, but in all the excitement he hadn't bothered checking. He went over to the bed and lifted it up in his hands, holding it at arms length. It seemed lifeless enough, didn't it?

He was examining it closely when suddenly...
