Your trainer takes his pen and goes through the pile of paper he just made you sign. He stops at a sheet that looks empty and put his pen to the paper.
"This is gonna be fun. "
He jolt something down, and suddenly your neck feels hot. Very very hot. You claw at it and realize it's the collar. It's... fusing with your skin. You don't know how else to describe it. Soon the heat subdues and you're left panting.
ZAP.
"Your master wanted a convenient way to punish you anytime, so here we go. "
He looks through his paper.
"Ah right"
He writes something else down.
"This is actually gonna make you happy. No more peeing or pooping. Your master find that inconvenient. The only drawback is that now you'll only be able to eat and drink liquids. The excess will be sweated out. "
For the next few minutes he writes things, and you feel strange every time he finishes a sentence. You can't believe this is happening, but it actually makes you kind of hard.
He finally gets up and look at you.
"That should be good for the magical transformation. Let's try some just to check. Sit."
You immediately feel the needs to obey and throw yourself to the floor, hurting yourself. Still you feel a wave of joy obeying his command.
"That was quite fast but the effect should diminish a bit after a week or two so you'll be able to sit at a reasonable speed. "
He claps his hands and you find yourself standing on the floor , paralyzed. You can't see anything and you realize the mask is back on. Worst, you can feel rubber everywhere on your skin. Sir pinches you and you flinch.
"Quite nice finish. Not a fan of leather myself, but... "
He claps his hands again and all the leather disappear, leaving you naked. You grab you penis finally free, and without being able to stop, you stroke it.
"Stop"
Your hand freeze.
"You don't seem to understand what a slave is to do. "
He writes something on the sheet and you look in horror as your penis goes soft and then gets smaller and smaller. Then a chastity cage appears around it.
"You are not here for your own pleasure, you are here to service your Master in any ways he sees fit. "
You think this is gonna be hell if you can't have sexual pleasure out of it, and then the collar zap you.
"tss tss. Can't have you thinking bad things about your master. Now let's see what your Master wants you to do during the day.
