Go out to the mall, but record link your computer to her webcam.

An idea pops into your mind, though you're not certain you'll be able to pull it off. Still, only one way to find out...

You tiptoe into your room, silently closing the door and turning on your computer. Thank God you've got the sounds turned off. Your parents have poured a butt-load of money into this computer and getting you all the games you've demanded so in a few seconds you're at your desktop.

All the computers in the house use the same wireless connection so it's easy to find your sister's computer. Thankfully the last time it was used it was left on. From time to time you've fancied yourself a hacker, and although it's not true you've been able to occasionally break into your parents' and sister's computers, seeing what they've stored there. You haven't actually taken control of them before, but you've read a bit about doing so, and even have a program that should do just that. You just need to set up what it'll do. Namely, record everything the webcam sees and store it on your computer.

It takes longer than you'd like, and you're afraid that the perv might start getting suspicious if you don't show up soon. Another downside is that he might see the computer in her room come to life.

"Distraction," you mutter, and sneak back into the hall and down the stairs.

Turning you clomp upwards, making a racket. "I guess he must be gone!" you say loudly, pausing outside her door and then walking heavy-footed to your own. "I think I'll go to the mall for an hour. Better grab my wallet first."

You can imagine the panicked beating of the perv's heart as you just heart the squeak of bedsprings and the light thump of his feet crossing the room. Quickly you hit the button to activate the spy program, lock the screen, and do what you said you were going to do. You're not sure how the hell you'll be able to stand an hour at the mall knowing the perv could be doing absolutely anything he wanted to your sister, but...

Well then again, your sister was only **** from an orgasm so she could easily wake up on the guy. Still, none of your business, you think, grinning ear to ear as you saunter down the road.
