I awake to a vague sensation in my nether regions. I look down and see an impossible sight. My foreskin is moving up and down my erect shaft but there is no visible cause. It gradually penetrates my sleep fuddled brain that I am being screwed. I try to move my hand to see what's causing the movement but it doesn't respond. I try my other hand with the same result. This is some dream, I think to myself. I try to thrust my hips but cry with despair when I realise I cannot move a muscle. I look around, my eyes are the only thing I can control, to see a typical Star Trek sickbay. I gather that my upper body is propped up while my legs lie flat. This accounts for my grandstand view if the proceedings. I realise that this must also be responsible for the lack of movement from my part, I am being held in some type of stasis field. All this time the motion continues bringing me nearer the point of no return. I try to study the situation logically, well as logically as one can when being screwed. I look at the movement and think, if I am being screwed then her head must be about three feet above the movement, so I look closely. As I concentrate there appears, like the Cheshire Cat, a huge grin. OK, I think now we're getting somewhere. The grin moves up and down all the time never stopping. Next I think there should be eyes and gradually two blue eyes appear, they are such a deep blue I feel as though I could drown in them. Hair is next; long blond curls are the order of the day. I'm getting accustomed to this now, whatever I want to see appears as if by magic. Moving down slightly I start to think about breasts. Almost immediately two huge watermelons appear. Aghast I lie there thinking what have I done. These monster mammaries are a complete turn off for me. I can see the effect immediately as my rod starts to shrivel like a deflated balloon. Concentrate guy, concentrate. I imagine much more manageable breasts with pert pink nipples and miraculously they shrink down until they are a perfect handful each, if only I could get my hands on them. Their reduction in size has an effect elsewhere. I didn't think it was possible but my erection is now larger than ever. The blue-eyed blond must have noticed the difference too because as well as the up and down motion I'm now feeling a clenching and relaxing. In frustration I try to drive my hips into the void but once again to no avail. Perfect teeth come next and make me think of them chewing something other than food. Milky white skin covers the features and grows downwards to cover the breasts. When it reaches the navel I stop and look towards the toes. Toe-nails appear and the skin starts to cover her legs gradually up past the knees I imagine I am planting tiny kisses and that causes the skin to grow. Slowly up towards her cunt I think about skin and blond hair until she is fully formed in front of me Her figure is pleasantly padded; I've never lusted after a matchstick, with ample curves that long to be stroked. If only I could move. A further pause for logical thought, this time it's even more difficult. If I can control her looks can I control her movements too? I decide it's time for her to stop bouncing and she does. The clenching stops too but soon restarts under my guidance. How much more of this can I stand. The answer seems to be LOTS. I mentally project to her the true use for belly dancing and she gets the message. Her breasts remain motionless but her hips move in a wide arc with me inside her. Still I'm near the brink but not near enough. I so much want to reach up and touch those pert nipples and kiss the dark aureoles the frustration is agonising. I look around again and see the well-lit sickbay, at any moment I expect to see Dr Crusher or one of her assistant's walk in. I hear the door swish open and that's enough to start me co.......
