You sit on the floor, hot and uncomfortable in the heavy rubber suit, but very aroused.
Jack rubs the thick shiny rubber on your gas-masked face, and your try to speak, producing just a strange muffled noise. He points to a strange bottle in the box. 'Take that, and open it, and spray it over the openings at your neck, back, hands and feet. I order you to do it, slave.'
Your heart is beating rapidly with excitement, and fear. This bottle is ultra-strong sticky rubber; it will seal you in this suit with no way out.
You take the bottle, unscrewing it with shaking hands, and spray it, first on your left hand, then the right. The glue shrinks and seals. You try pulling on the gloves, but they are attached to your suit permanently now. You lean down and spray the tops of your boots, and then around your neck. The glue hisses gently as it seals you in your rubbery prison.
You hand the bottle to Jack, who sprays your back with the rest of the bottle. You wriggle as the suit tightens around you, conforming to your body all over. You touch your new permanent body, the hot black rubber making your dick rock-hard.
Jack pats you on the head, and you make happy noises as best you can. He rubs your smooth, shiny chest, and you close your eyes, your dick rock-hard, finally getting your sexual fantasy.
You are Jack's shiny leather slave, for the rest of your life you will tend to his every pleasure or be beaten. There is a squeaking noise, and you find your breathing restricted. You open your eyes to see Jack screwing a pressurized rubber canister onto the nozzle on your mask. 'Eat it. I order you.'
You hesitate for just a moment, but you have to obey your master. You spin the release to max.
Immediately a flood of thick, hot rubber flows up into your mouth. You start to choke, unable to breathe, the goo filling your insides. You struggle on the floor as rubber fills your lungs, flowing into your stomach and up your nose, and you suffocate.
You lie on the floor, feeling yourself bloating with rubber, not breathing. You don't have to. Soon you are full, and the rubber leaks out from your ass and dick, filling the suit, inflating it, until every inch of you is full of and surrounded with rubber.
You try to speak, but you no longer have vocal chords. The rubber has gotten into the mask, so everything you see is through a dark goo. Your head feels weird; you can sense the rubber seeping into your brain!
You try to scream as your mind is warped, and your brain is overwritten, turning you into a rubbery mindless drone, wanting only to obey your master.
You are a tall, chunky, muscular rubber machine.
Your body is composed of metal bones, on top of which are latex muscles and a skin of hard, tight rubber in the shape of defined pectorals and thick muscles. You have a thick, hard plastic dick and a set of balls with a valve to hold any type of liquid. Your huge hands and feet are chunky boots and gloves, with little movement, and your head is a large, expressionless gas mask.
On your chest is written 'SLAVE DRONE: Property of Jack Clay'. Your simple mind knows only to obey your beloved master.
