Take a closer look at the sister/suit

You find yourself staring at the hole in her back, trying to look into the inky darkness within. It doesn't make sense, surely you should be able to see… something?

After a brief battle with your common sense curiosity wins out and you reach into the hole. It is like reaching into nothing. Your hand simply vanishes into the darkness. You can't feel the inside of the skin and from the outside, there is no sign that your hand is in there. No trace of the bulge you'd expect to see, no sign of motion even when you wave your hand about. Even when reach deeper it continues to defy all logic. The skin remains flat and still, laid out on the floor. You are past your elbow now, in a world that made any kind of sense your hand would be sticking out of the ceiling of the flat below yours. You are about ready to give up on the whole portable hole routine when something happens.

Your arm has sunk up to your shoulder when you feel a pleasant tingle in your fingers. The tingle spreads up your arm and when it reaches your shoulder Zoe’s arm re-inflates. You watch it springing back to life in an instant. Surprised, to say the least, you jerk back only for the restored arm to move with you. It's not until you have stumbled back a few steps that you figure it out. Your sister's arm is now attached to your shoulder in place of your own arm!

“Woah!” you say wiggling your fingers and seeing Zoe's arm responds as if it was your own “Now this has possibilities.”

You hold you suits arm against your other, still normal arm. Pressing the palms of the two hands together you feel the how rough your own hand is by comparison.

As you thought your normal arm and hand are much larger than the suit arm. It's clear there is no way your real arm could fit inside the suit and yet that is exactly what's happened. Touching the skin of the transformed arm it feels warm and smooth, like regular skin.

For the next step of your test, you take a firm grip on the slim wrist and give it an experimental tug. It stays attached to your shoulder as if it's always been a part of your body. You pull harder, only managing to wrench your elbow.

“Ow! Okay, that's on there pretty good” you say scratching your chin with Zoe's dainty fingers “Maybe, if I…?”

You try a different approach. Grabbing the suit where it joins your shoulder and peeling it down like taking off a long glove. This seems to do the trick. There's only a slight sense of resistance, like static cling, as your arm re-emerges from the black. Once again the suit arm deflates, reverting you hollow skin as you pull out.

“Okay that's pretty awesome,” you say excited by the possibilities now spinning through your head. “I could really have some fun with this….”
