I. Lure
Generally speaking, I didn't typically go out on hikes with the intention of earth-shattering orgasms or life-altering sexual escapades. It's not that I had anything against exhibitionism or an occasional jerk outdoors, but that just wasn't where my head was at on pleasant Saturdays in the summer. It had long been a ritual of mine to drive into the national park on such days for a bit of off trail hiking. Some might call that ill-advised to do alone, but I was never the sheepish type and was fairly experienced with a good sense of direction.
That Saturday had been nothing but typical all the way out to my usual parking haunt. Looking back with the knowledge I have now, I'm fairly certain that even had I known what was in store I would not have gotten back into that car. Hell, I might have thrown away the keys.
I spent an hour off trail climbing through rocky forested terrain, but it was on my way back that my life got a whole lot more interesting. Nestled down near the bottom of a small valley was an outcropping of rock with a strange slit in it that at a distance could've been five feet deep or a hundred. I'd paused by this very oddity on my way out because I'd never seen anything like it before, but now that I walked by it a second time I felt a compulsion to stop and examine it further.
I had no flashlight with me that day and it's likely that if, peering into the hole, it had just been cold darkness staring back, I may very well have been on my way. But looking through the rocky slit I didn't see darkness. An inexplicable soft pink glow shone back at me. It was so curious a thing that I was immediately enraptured. My mind didn't even consider alternatives. I dropped my backpack at the entrance and slipped inside.
The depth of the passage was evident even before my eyes had adjusted to the darkness. A comfortable breeze emanated from somewhere up ahead that was pleasantly inviting. Sidestepping deeper, my hands slid over jagged rock. The blinding white light of the outside world began to fade, and inevitably was replaced by the incessant pink glow ahead. My progress forward became measured by changes in the passage around me. First it was the surface of the walls -- patches of a soothingly smooth material appeared, then soon replaced, the jagged rock. It was as if I was gliding my fingers over the sensitive skin inside one's thigh. Next the floor changed. The ground was no longer solid rock, but had softness that gave way with each step. Here I encountered my first obstacle as my shoes became stuck to this surface.
This sequence of events should have been steadily raising an alarm, but I felt so compelled to investigate the light that I was soon slipping out of my shoes and even my socks to dislodge myself and continue forward. The spongy flesh beneath me seemed to grip my feet as I walked, but it did not hold me in place.
At the end of the tunnel was an opening into a small chamber wide enough for my outstretched arms. The source of the light seemed just beyond now and was bright enough that I could clearly make out the pink, organic nature of everything around me. There was an inexplicable dull translucence to everything through which the light seemed to travel. Ahead was a slit in the flesh that bore an eerie resemblance to a labia. It stood waiting and my mind presented no choice but to enter.
Here, for the first time, I felt a mild claustrophobia. The walls were silky to the touch with a warm dampness, much like the inside of one's cheek, but they wrapped around my form snugly. Step after step I pushed forward with deep curiosity until at last my leading arm broke through to empty air on the other side. Like a middle-aged rebirth, I fell out onto my knees on an even softer floor than before. The fleshy pink surface jiggled ever so slightly at the impact.
II. Learn
This chamber in which I now found myself was the source of the dim light. Embedded within the ceiling it cast a calming glow across the walls, which absorbed my attention with fascination. The patterns were reminiscent of human muscle, though curious circular flaps dotted the walls, floor, and ceiling in no apparent organization.
With my feet once again beneath me, I found my hands drawn to the walls and the flap nearest me. It trembled at my ginger and exploring touch, from which I recoiled slightly. The trembling gave way to movement and then suddenly the flap opened to reveal a creature unlike anything I'd ever seen. Moving outward toward me, its form was that of a pink snake, though such a description suggests danger that it did not telegraph with its posture. It seemed highly prehensile -- almost tentacle-like -- with a continuous fleshy body bereft of markings. No eyes, mouths, or other features could be seen, though it clearly had a strong sense of my presence and appeared to react to my movements. Several feet of its slender body protruded from the flap as its head leveled with mine.
By now my sense of judgment had clearly dissolved under the tantalizing pink light, else I surely would have approached this unknown entity with far more caution (or even ceased to delve this far). Alas, my mind was ablaze with curiosity and I moved my hand out to touch my new company. With some eagerness it met my outstretched hand and I was treated to the silky warmth of its slightly slimy flesh. It seemed to delight in the feeling of my own skin and nuzzled my palm endearingly. This acquaintance demanded the entirety of my attention and so I never even noticed the slit from whence I came dissolving away behind me. Nor did I notice half a dozen other tentacles cautiously emerge from the floor around me. I startled at the feeling of one snaking up my lower leg and upon seeing the growing crowd around me I uttered a nervous laugh.
The tentacles took great fascination in my shirt and shorts. They seemed to understand that the clothes were not part of my skin and several crept into my sleeves curiously while others wandered up my pant legs. I held my arms out and watched with a nervous smile as they explored, but my attention was soon attracted below. One of the surveyors had stumbled upon the package tucked snugly in the front of my boxers. It seemed to know part of me was in there and it prodded innocently through the fabric. That pulled another nervous laugh from my lips as my dick twitched with interest.
With it rubbing me through my boxers my mind was racing. Who was I to deny it more knowledge? My body trembled ever so slightly as I unbuttoned my shorts and dropped them to the floor. The curious tentacle slid out from under them and rapidly returned to my growing bulge. With its interest affirmed, I looped my fingers under the bands of my underwear and pulled them down. My cock and balls spilled out into the foreign air -- a feeling that always got my heart pounding. I was half erect already and this action drew attention from the others. Feeling committed, I pulled off my shirt to present my complete naked form.
Whilst several of the tentacles poked and prodded at my exposed and engorging genitals, others were exploring my arms and legs, wrapping themselves gently around me. One moved up toward my face, seemingly interested in my mouth. It angled its head around in front of me quizzically before nuzzling up against my lips. With all caution having been thrown to the wind by this point, I opened my mouth to allow it entry. It slipped in gently and I had my chance to explore its silky flesh with my tongue. It tasted surprisingly pleasant, with mixes of both sweetness and saltiness in proportions that suited me. The exploration continued logically and my eyes widened as it pushed further into the back of my throat. My gag reflex fired quickly and it recoiled out of my mouth as I lurched forward. To my surprise it seemed to understand what that meant and took no offense to it, but my situation had developed in other ways.
I had scarcely paid attention to them, but the tentacles around my arms and legs had wrapped snugly enough to take hold of me. Shortly after recovering from the bout of gagging, I felt something below me that set my heart racing. I bent forward to see a new, larger tentacle that had emerged beneath me and found my asshole. As it nuzzled the tight opening I moved my arm to shoo it away... except my arm didn't move. The tentacles exercise a firm hold over my limbs and I became vocal while fruitlessly trying to move my body. The tentacle at my rear looked to be the width of my arm and I could feel it applying more and more pressure. I started shaking my head and pleading as though they could hear me, but the force against my sphincter only increased. The tentacles around my legs spread them gently which, I quickly realized, was an attempt to expose my asshole better. Eventually the pressure became so great that I knew it would get in. Hyperventilating now, I exerted an effort to relax my sphincter and within seconds the slimy head penetrated me with an inaudible pop.
