I was hoping that working for U.N.I.T would be exciting but instead I've missed all the action and am stuck on clean up duty with doctor Smith, clearing up cybermen and cybertech for study. I say with doctor Smith but he's mainly been in his mobile lab over the last few days, I the lowly grunt am left to do all the manual labour, large metal cyborgs aren't exactly light either.

Tired, exhausted and needing a break I enter the lab to check on the doctor.

"Hi doc, how's it going." Normally such an action would be followed by an annoyed sign but the usual frustration was instead replaced with a smile, which was slightly unsettling.

"Ah, just the person I wanted to see." Now that was strange, maybe he's spent to long in this lab and gone mad, he's never wanted to see me before.

"I've discovered some amazing things in my research of these cybermen. I've been working on something that I want to test out." He wants to use me as a guinea pig, now it makes more sense, I'm strangely more relieved, he's his normal self.

"Um, isn't testing this stuff dangerous?" The doctor looks at me with his usual frustrated annoyance, like he was trying to explain some obvious to a clueless child, he reminds me of several teachers I had growing up.

"Dangerous? No, I've been studying the code, it can't convert you or anything. It's a device to increase efficiency, I've seen that you get tired and exhausted working all day, this is merely something to make your life easier." He's worrying me again, or maybe I have just misjudged him. I sigh.

"What do you need me to do doc?" His face lights up like a child at Christmas at my willingness to help.

"Just stand here." I move to where a small, narrow, 6ft metal tube rested in the lab, with one side with a cut out allowing for access inside.

"Please get in." I hesitate for a moment before following orders and squeezing into the tube.

"What is this for?"

"I need to scan your body to optimise the device. Hold still." Thankfully U.N.I.T training had made that easy after hours of drills and standing guard. Suddenly metal arms shoot out of hidden compartments inside the tube and close heavy steel shackles around my wrists, ankles, lower and upper legs, upper and lower arms, and my waist. I try to move but i can barely move a fraction of an inch, the restainst are to firm and refuse to give. A line of cold blue light run up and own my body, making it tingle slightly.

"Right, the scan is complete, now to test the device." At this he picks up a small metal collar and walks up to me, unable to move I just watch as the open collar moves closer towards me before I feel the cold metal close around my neck. I feel a sudden sharp pain as several needles stab into my neck and my hands instinctively try to move up to pull the device off but are met with the unmoving steel restraints. I cry out as a jolt of electricity sears through my neck and then I just stand still. I try to ask what is happening but my mouth refuses to move. I begin to panic as I fail to move my fingers and toes, my body no longer responding to my commands. The old scientist smiles menacingly.

"Let begin the testing. Who are you?" My mouth moved without thinking, I hear my voice but they aren't my words.

"I am your servant, master." I feel restraints release and remove themselves back into the tube. I try to move but my body still refuses, despite my brain crying out to run.

"Step out of the chamber." My body that refused to move only seconds ago steps forward out of the tube and I stand at attention.

"Strip." My heart beats in fear and I try to fight against my own body as I remove all my clothes and stand naked in front of the doctor. I wish I can cover myself as I feel the cool lab air on my exposed skin.

"One last test left." Smiling he undoes his trousers and pulls out his cock. I fear that I know what is coming.

"Suck." My body moves towards him and lower to my knees and place my mouth over their cock and begin sucking it and moving my head back and forth, my tongue massaging the head of their cock, my senses filling with their smell and taste. For some reason I also feel my cock getting hard in response but frustratingly I can't move my hands to do anything to relieve myself. Suddenly my mouth fills with cum and as much as I want to spit it out I swallow it down and lick his cock clean. Moving my mouth away I kneel looking straight at the cock that I just blew.

"Excellent, the device works perfectly. You will make a great prototype for my plans. Follow me." He does his trousers up and walks towards a wooden cupboard and opens it and walks through. I unwillingly follow him into the cupboard, only to find a large room with a console in the middle of it. It's a TARDIS. Suddenly I realise that I'm in far more trouble than I thought I was, this must be the master, and I'm fully in his control and trapped inside his TARDIS.

"Travel to my quarters my dear slave, I'll meet you there shortly. First I must begin my plans for the domination of earth, starting with the assimilation of U.N.I.T." I walk out of the console room and down a corridor, a feeling of dread fills my mind as I hear the master's laughter echo through the ship.
