Chapter 5 by FFFA6

What's next?

You push yourself impossibly further

You wait for twenty minutes before the pain is finally gone, before you resume walking backwards slowly. It doesn't occur to you how dangerous this really is, even as your ass hits the wall, your arms in your ass up to the shoulder. You spread them apart with all your might, moaning loud enough to be heard miles away. You look back at the mirror behind you, and your eyes widen at the sight. You can clearly see the path of your arms, and even crazier is the gaping hole between your arms, letting you see inside until your fingers.
