*****
I awake on my back feeling cold metal beneath me. It is not entirely uncomfortable, as the metal seems to curve around my body, leaving me in a shallow recess. I immediately notice my nakedness and try to look around, but my head is immobile. Though I can open my eyes, I see only infinite darkness, as if I were blind. My ears also seem to not be functioning. As if they were plugged, I can hear nothing but the sounds of my body - heartbeat, air rushing in and out of my lungs, even the creak of muscles and ligaments. I relax and try to gather what I can about my surroundings. A band over my forehead keeps my forehead still. My hands and arms are encased up to the shoulders in the same metal, as are my legs up to the mid thigh. Strangely, I cannot flex my fingers or toes, as if the metal were formed exactly to my body. A band about six inches wide stretches across my chest. Although it is also cold it seems more flexible, moving up and down with each breath I take. Noticing this, I try to take advantage of the flexibility and writhe myself free, but as my muscles bunch up to move, they relax, ignoring my brain's urgent messages to do otherwise.
I give up with a frustrated sigh. When I do, the chill of the metal sets in, raising every hair on my body. My nipples stiffen slightly, and I can feel my ass clench in response to the cold. Ages seem to pass, and the cold becomes a dull pain throughout my body. Suddenly, something begins to creep up the back of my neck, warm and...wet. At first I think my body is simply playing tricks on me, but then it pours over my chin, running through my beard. My jaw clenches in shock as the thin...thing crosses over my lips. Horror flashes through my mind as it enters my left nostril. I attempt to blow it out, but the thin appendage continues. My nose is assaulted by a sharp, musky smell. It hits the back of my nose, and it's about to go down my throat...but it doesn't. It goes somewhere else, sending jolts of shock through my body as it goes where nothing belongs. After about a minute, the sensation suddenly disappears. Confused, I breathe in. The air still is blocked around it, and the musk is just as strong, but I can't feel the thing itself.
Another jolt, and I see stars. Although I can still feel the cold, it feels...good, somehow. Every wave of cold sends a little tap of pleasure rather than pain. The belt around my chest sends little sparks of pleasure as I breathe, as if my entire body was now an erogenous zone. Something descends on each of my nipples, cupping them like two tiny thimbles. Suddenly, tiny needles jab into each nipple, and I wince, expecting pain, but instead my mind is met with a rush of erotic pleasure. Despite the cold, I can feel my cock slowly begin to inflate with blood. Two tendrils circle my balls, tightening around them and pulling them away just enough for what would be a tinge of pain, but is instead another rush of pleasure. Each tendril begins to circle my balls, somehow never stopping, just winding around them. My cock now touches against my chest, and I can feel the head slowly pushing out as it continues to become erect.
