As you beat your way along the trail the foliage grows denser and closer, and the ground muddier.

You begin to question if you made the right choice.

You hear the howl again, louder this time, and break out into a run. You make a valiant go for it before you trip on an exposed root and topple face-first into the mud.

When you manage to raise your head back up you feel a rumbling and the ground ahead of you begins to rise. It bulges higher and higher until it begins to shift, taking on the shape of a huge muscular humanoid made of mud. Atop its moss-covered shoulders where a neck would be instead emerges three animal skulls: a wolf, a deer, and a crocodile. It looks down at you and stares.

After a moment the wolf head howls and the wind carries words across your ear:

You... defile... these... lands...

Shit.

The monster advances and you scramble to your feet to make an escape. In your haste, though, you don't notice your loincloth snag on a bramble, tearing it off and throwing you off balance, sending you careening into the mud yet again.

You plant your hands to get off your stomach but feel a wet, heavy hand on your back pushing you down. You struggle but the creature is far too strong.

These... lands... defile... you...

You feel something large, wet, and sticky push at your asshole. You have no power to resist and soon you feel its cold, slippery length entering you, stretching you wide. You yell in pleasure as the monster begins fucking you roughly, pounding you over and over with its oversized, muddy cock. The very mud below you seems to come alive, sucking at your hard aching dick buried in its depths.

The monster's thrusts become erratic, and it roars just as you feel the gush of it release inside your asshole. The sensation sends you over the edge, and you let out a roar of your own as you empty your cock into the wet earth, and collapse.

You become dimly aware of being lifted into the air right before you slip into unconsciousness...
