God's Mouth [creepypasta]

Description

Beware of God's Mouth. "Do not enter" Something is quite odd about this abandoned cave. The path seems endless and it's just a straight shot foward. But why is it that when someone tries to go backwards in the cave, the path is not there? Just... a cold, hard wall. Keep proceeding foward... but keep a sharp eye behind you. I think the walls are moving closer as if... the cave is trying to swallow you.
