Visit your sister under the cover of the night.

You know perfectly where your sister is, Chad's house. She brags enough of how she always spend the night there and fuck him all night long which is bugging you not only because you never managed to get a girlfriend to go farther than a quick hand job with you and because Chad is an asshole that made your high school years a living hell.

You get home to wait for the night, laughing about what will happen to your sister the next day with her public antics at the mall and the extra leverage you have with the video.

You have to find a way to go in Chad's house to see what will happen when you change a few things around.

You have a plan but it implies going into the house for it to work. But how?

You think about something, a sample of someone lets you turn into the person, so what about others things made from living materials.

You pick a cap made of raccoon fur you bought as a kid in a national park. Small, agile, able to climb and most importantly possessing working hands, the furry rascal you could morph in using this as a sample should be able to operate the bracelet.

You try it on a 5 minute timer and spend most of them having fun jumping on the furniture feeling like a superhero in the light muscular body. Your hunch was a good one, you can use the bracelet in raccoon shape. It will also be a good camouflage as you wander around.

You eat some pizza left over in the fridge before tying a string to the bracelet to get is as a sash on your nightly excursion. You also put a small screwdriver and x-acto knife, you never know what you might need.

You take a few of your hairs and put them in a small plastic bag as a sample to become yourself in advance and leave a few others in the house and the backyard. You also take two others with hairs from the cap and your sister.

At about 10pm you turn yourself into a raccoon for a day, you can always turn back into yourself with your sample.

You run through the backyards for a few blocks in the warm summer night. You get to Chad's house and see that he left his room's window open to get some air.

You climb the tree in front of it and spy inside.

Both he and your sister are asleep, naked on the bed without even a sheet on them, you can see various dildos, but plugs and cuffs on the bed. He was not kidding with the tattoos, your sister is really his bitch.
