That musical howl pierces the night again and I veer towards the sound, picking my way through the dense brush and cursing my choice of shoes. The forest is so dense none of the full moon’s light shines through the canopy, leaving the floor in an impenetrable darkness. Even my flashlight doesn’t seem to help.

I crash through the woods in the general direction of the howl, but there’s no sign of any strange animals. There’s no sign of any animals, actually. No night birds sing, no crickets chirp. Even the wind through the leaves seems to have gone silent. The back of my neck prickles as if there are eyes on me, inexplicable terror freezing my blood in my veins.

The howl rips through the darkness like a tangible thing, echoing between the trees until it seems as if it’s coming from every direction at once. It’s closer now. Far too close.

I take off in a random direction like a startled rabbit, wild and thoughtless with animal terror. I don’t think about which way the path is, or the nearby highway. All I care about is getting away from what I can feel in my bones is a dangerous thing.

I don’t make it far before I hear footsteps behind me. Pounding, heavy steps, like whatever hunts me is taking massive bounding strides. Whatever it is must be huge, far bigger than any buck. I push myself to run harder, stumbling in my panic, but the creature grows closer by the second.

I hear it’s labored panting a moment before a crushing weight hits me from behind, forcing the breath from my lungs. My flashlight flies from my hand and into the dense brush, shrouding the trees in darkness. Suddenly I’m wheezing into the dirt, crushed to the earth by something heavy and hot and covered in thick fur. I can feel powerful muscles rippling against my back when it moves against me.

The monster shoves a wet nose against my neck, breathing heavily against my skin and inducing a shiver despite myself. A long, hot tongue swipes over me, followed by a growling groan. I’m too stunned to move, quivering in fear as I wait for this thing to devour me.

But the creature does no such thing. Instead it - or, he, as is quickly made abundantly clear - presses me more firmly into the ground with his hips, and I feel something hard and throbbing against my ass. The creature growls again, and I can feel the vibration of it against my spine. He pushes into me rhythmically, rutting against me, and a new terror floods through me.

I begin to struggle again with renewed desperation, clawing at the damp forest floor to drag myself out from under this beast. The only thing worse than being killed by him was being fucked by him, surely. He huffs in annoyance - a strangely human sound - and an impossibly strong arm matted with fur is shoved under my chest, holding me firmly against him. A giant hand paws roughly down my side, curved claws catching in the fabric and tearing it away as if it were paper.

He only seems to grow more excited when I’m exposed to the chill night air. I’m both shocked and ashamed to feel wetness cooling between my legs. The monster’s insistent humping grows more frantic, his throbbing cock slipping between my cheeks and rubbing over my pussy as he tries to line himself up with my dripping hole. I thrash beneath his weight, desperate to get away before he can ruin me. In response, hot breath washes over the back of my neck. Long, sharp teeth clamp gently around my throat, just hard enough to dent the flesh. I stop struggling immediately, the message clear.

The head of the creature’s cock pokes at my entrance and I can’t muffle my gasp. It’s so hot, so big, I can feel just the tip stretching me. He gives me no time to fall back into fear, shoving into me as deep as he can manage with a satisfied groan that rattles the teeth against my neck. I cry out, afraid I’ll be split in two. It’s far bigger than anything I’ve ever taken. I’ve never felt so utterly full before.

The monster pumps into me at a steady pace, the hand wrapped around my chest cupping my belly instead, pulling my hips more firmly into every thrust until I’m sure the head must be in my womb. His grunts and the wet sounds of his cock pounding into me fill my ears, his jaws flexing around my throat. I’m ashamed to feel arousal dripping down my thighs, familiar heat growing in my stomach despite the ache of being stretched so completely. How could this be turning me on?

I don’t know how long he fucks me into the dirt. I stop caring after awhile, unable to focus on anything but the constant, powerful in-and-out of his cock, the heat and weight of him keeping me exactly where he wants me. I can’t keep my choked moans hidden anymore, new sounds pushed from my lips every time he bottoms out. The pleasure keeps growing, the pain gone entirely as my body molds itself to this unknown monster’s cock. My thighs begin to quiver with the ecstasy of it, stomach tightening under his claws and pussy fluttering around his throbbing dick.

The creature’s thrusts increase their speed, the movement of his hips becoming jagged and fevered. His fangs, still clamped around my neck, tighten enough to draw blood. His grip tightens until my bones creak beneath the strain. My moans are more like sobs now, my fingers clawing into the dirt. I’m dimly aware of the beast pushing into me one final time, of his hips grinding hard against my ass, of the long, satisfied growl that rumbles in his chest, as I’m finally forced into orgasm.

I shudder helplessly in his iron grip as my entire body clenches almost painfully, my pussy contracting violently around his cock. Scalding heat floods my belly, rope after burning rope of it stuffing me impossibly fuller with every powerful throb. His dick seems to grow somehow larger as he cums, and the renewed ache only makes me spasm harder.

After long moments of grunting and twitching and writhing we both melt into the forest floor, spent. He’s still rutting into me, gently now, his cock twitching and somehow still hard. I try again, weakly, to drag myself away from him and quickly find that I can’t - his dick really did get bigger, lodged inside me for as long as he’s erect with a seal so tight not a drop of his cum has leaked out. I can only hope one round is enough for this thing.
