Mark grinned at him. “There is someone impatient. That was only form one, I have at least one other planned for you. Lets see. You will change into this form whenever I say “Aidan mount form” and will keep it until I change you into another form. But now to your next form, the normal one so to speak of. This second form will be an ordinary sized house cat with the same fur pattern. So that means for that form you will shrink down to a smaller size. You will keep your collar, but your saddle and reins will merge with the collar in that form so it won´t hinder you in any way. Everything that is in your saddlebags will be stored in the collar as well, but weight nothing extra.”
Aidan nearly cried in frustration when he shrunk down to a normal size house cat. In that form he wouldn´t hurt Mark enough to gain control. He felt the weight on his back vanishing when the saddle merged into the collar, keeping him agile.
Mark saw the frustration in Aidans eyes and laughed about it. “You thought I would give you the opportunity to go against me, Aidan? No, you are completely unable to harm me in any way or any form. You will be able to speak normal, but only I can understand what you say. Anyone beside the two of us will hear normal cat noises, meaning meowing. And if I say “Speak cat Aidan” even I won´t understand you until I remove that command. Whatever form you are in you are very loyal to me as your owner and will follow every order I gave you that's not hurting yourself. Now back to your forms. Like with the mount-form nobody will question it when my house cat is following me around, wherever I go. In either form you will be housebroken and eat everything I gave you as long as it is eatable. You will only drink water or milk except I tell you otherwise.”
Aidans look had changed to horrified again. Mark had effectively robbed him of any way to change back beside using the laptop. And how likely was it to get to it when Mark made him loyal to himself? Most likely he would follow Mark everywhere without any time to get to the laptop. He could only hope that he could get to it when Mark slept now. He couldn´t ask anyone for help and if he would complain to much Mark could just silence him.
Mark saw the changed look on Aidans face and grinned down to him. “No worries, your life will be good. You will always be cared for, so stop looking so sad. But I have thought about a third form for when you can´t be around as an animal. And no, it won´t be a human or anthro form. If I say “Aidan inanimate form” you will shrink even smaller, into an inanimate key chain as a kind of a lucky charm for me, made of plastic. In that form you will also keep your fur pattern and be in a sitting position, your tail wrapped around your paws. The chain will grow out of your collar like the reins of the mount form, only with a easy to open ring in the end. If you are in that form you can´t be taken from me and if I forget you somewhere you will just teleport into my bag after a minute of me being more then a hundred meters away. But you will be unable to move or speak in that form.”
Aidan couldn´t believe Mark. First a pet that he could use as a mount or a companion and now an inanimate lucky charm? Before he could say anything he started to shrink further, moving his front-legs in front of his body and sat down. He could feel any muscle hardening into lifeless plastic, the same applies to his limbs and body as a whole. His mouth turned into a smiling line and his eyes started shinning, totally unmovable. A tug on his neck told him the chain grew out, connected to his collar.
Mark took Aidans key chain form form the ground, turning it around to look at it from all sides. Satisfied he sat him down on the desk next to the laptop. “For now I will keep you in that form, no need to hear you complaining. Let´s see. You have your forms and purposes to each of them, but maybe I want to torture you a bit more, even when you will have a good life. So I know that you still can feel the former socks on your skin as itchy and rough as before and the smell and taste from them in your face. Not to forget your erect but sealed cock down there. But you will never be able to ignore them or get used to said things. You will be unable to lie to me, but can´t comment on your sock-skin and its smells and tastes. Finally to topple your last hope for returning to normal by yourself you won´t be able to use the chronivac ever again.”
If Aidan were able to he would start to cry. Mark was right, he had just crushed his last hope of ever returning to his old life. He was a prisoner in his own body, forced to do Marks bidding as a mount or loyal pet and tortured by his former socks and his own cock forever.
“One last thing. Nobody beside the two of us will remember you were human, so Aidan Starns never existed. Your things belong to me now until I leave this flat, then everything inside it will either vanish or be owned by the next tenant here. Only what I take with me will be mine then.”
Aidan couldn´t do anything but hope this all was a nightmare, but he was sure it wasn´t. Mark had effectively removed his old life from existence.
