On the far side of the tunnel

You blink against the light of the sun as you emerge. Your sex throbs against it's captive captor. It's so big. You'd swear it must be as big as the trees around you but know that isn't possible. You pull at the harness yet again, hoping to adjust it but your fingers just slide off the well lubed surface making it squelch back against your entrance.

You take a few more trepidatious steps and look over the edge of the road.

The road continues to your left, winding back and forth, back and forth across the face of the mountain, covering maximum distance so that the slope is easier. If you go this way, you know the trip will be longer, but you might be able to move your weight back to your heels and try to minimize how much more air you pump in with each step.

However, below you is a set of stairs. It extends down the mountainside, meeting back up with the road once or twice as it descends. If you try to take these stairs you know the way will be shorter, but you know the drop from each step will make it all but impossible to avoid putting the maximum pressure on the pump, filling you more with each step.
