Continue On.

You decide to just suck it up and continue on. Your cock should know better anyway.

You continue on through the bushes, before long you notice that even in the bright starlight, something is casting a shadow. You are still a fair distance away from it for now though so you can't even see anything that could be causing it.

A few minutes later though, after pausing at a bush with lip shaped flowers (one decided to bend down and engulf your hard cock to suck you off), you push on and stop dead in your tracks.

It was a black bricked wall!

You open your eyes in amazement, clearly a brick wall running across your path in the middle of a forest was not high on your list of expectations.

You walk up to the wall and examine it, it appears to be a rubber brick wall, each brick is stiff and hard like normal rubber, it is very slippery though as though a film of lube or oil is coating it. It's also very high, easily twice as tall as yourself.

It continues on in both directions though, you will have to circle around it to get past it.
