I awoke with a start, puzzled. My bedroom was lit only by wisps of moonlight that shifted ephemerally with the fast-moving clouds. There was a deep and brooding silence, expectant, like a held breath. I could see no one else in the room, yet I felt eerily like I was being watched. I tried to turn my head to look at the clock on the nightstand, but I couldn't; no matter how hard I strained, I couldn't move.
On the edge of my vision there was a slight movement, just a quick blur to my right. I tried to look over that way; I could see nothing but the curtains fluttering slightly in the summer breeze. Then...
There was a patch of darkness, like a square of night that seemed denser, a deeper black than the rest of the shadows in the room. Suddenly it moved away from the window and began sliding up the wall. My heart was pounding as I watched it flow up the wall, then across the ceiling until it was directly above the bed. It seemed to flex and move, almost to pulsate like a beating heart. It was growing, spreading, like a dark cloud. Then, to my horror, I realized it was beginning to sink toward me.
I strained against whatever was holding me in place, in vain. I tried to scream but all that came out was a terrified whimper. I didn't know what the hell was going on, only that the experience was scaring the shit out of me!
A deep and icy coldness spread over me as the cloud dropped over me. A pressure was on my chest, like a stone beginning to crush me. The cold and the weight spread over my entire body, making me numb.
Suddenly things began to change, I suddenly began to feel tingly all over. I could feel my nipples begin to harden beneath the silk of my chemise. There was nothing remotely arousing about the situation, yet I was beginning to feel horny.
I felt the sheet sliding away, completely uncovering me. I could feel hands rubbing across my body, yet still I could see nothing. They weren't rough but gentle, caressing every curve, driving away the coldness. My breathing was beginning to slow, to deepen; the terror was still there but it was being overwhelmed by this new thing, buried beneath the weight of whatever lay atop me. I could hear ragged breathing by my ear, then a warm moist tongue began tracing the line of my jaw. The hands stopped atop my breasts, and they began rubbing at my nipples through the thin material.
I could suddenly move a bit, although not on my own. My legs parted slightly, and the hem of my gown slid upward, leaving my pussy bare to the night air. Something now began to rub at my clit, back and forth, back and forth. I could feel my juices starting to flow and I moaned softly, not with fear but with need.
There was the purr of tearing fabric, as my chemise split down the middle. An unseen mouth closed over my left breast, and I could feel a tongue lazily circling my nipple. I arched upward slightly, against my invisible lover, as a finger probed the wetness between my thighs. It slipped inside me and I shivered with the deliciousness of it. Gently it turned, circled, pressed forward, then withdrew...over and over, finger-fucking me as I grew wetter and wetter.
