It's a beautiful day. The sun blazes down on the high leaves of the trees, shadows undulating across the verdant floor. A light breeze snakes between the trunks. A stream trickles down the side of a hill, the water cool and clear.

Another stream joins it, this one less clear: an arc of fluid bursting from beneath my thighs. My legs are spread far apart, but a few stray droplets of piss manage to find their way onto my skin regardless. I pay it no mind; I've had worse on there.

As I relieve myself, I curl my toes, the sensation of the moss beneath my feet almost orgasmic. My eyes narrow and I lose myself momentarily to the living presence of the forest. The wind caresses my bare skin, and the rush of the leaves sends a shiver through me.

My stream ebbs, reducing to a patter on the ground before ending entirely. Without thinking I reach into my pubic bush, then lick my fingers, tasting my own urine. Salty, but enjoyable.

But the urge is still there. The ever-present urge, the urge I have to fight to survive.

The urge for self-pleasure.

Grunting, I lollop down the side of the hill, arriving at the base of a thick maple tree. Its bark is mottled brown-grey, but this tree is young, and its body remains in one piece - no flaking. Perfect, in other words.

I lean against it and drag my nipples against the rough surface. The feeling is equal parts pleasure and pain, but neither can compare to how it will feel in a moment. I drag them back again, leaning side to side, small gasps escaping my mouth.

It isn't enough, so I decide to let go and surrender to the urge. I wrap my arms as far around the stout trunk as they'll go, and plant my naked groin against it. Bending my knees, I begin to rub my cunt into the bark, the pleasure and pain increasing tenfold. My gasps become growls and moans, whimpers and sighs, as I'm lost in the ecstasy of punishment.

It doesn't take long. I feel it build inside me, the slow burn demanding release, and then it arrives. My body erupts into rapture, and I scream as something new splashes from between my legs, saturating my thighs, legs and feet. In my daze, I hear the flap of wings, and look up to see a bird taking flight from the tree I'm making love to.

Satisfied, at least for now, I step back. The stain is very visible; I have marked this tree as mine. With a smile, I walk away.

(Heya! Very weird scene, but I'm in a very weird mood. I'm looking for something, as the title says, primal. How you want to take this is entirely up to you: if you'd like to play another feral human, someone lost in my woods, or even some creature of the forest, I'm open to any of them. Please be literate, and send me more than a one-line message. Hope to hear from you!)
