“Is that it?” I asked, staring into the small metal box my Alpha had opened in front of me. He’d been very keen for me to see it – whatever it was. Inside, a thick black liquid half-filled the base of the box, reflecting some of the light in the room. I could almost see my curious face in it, the reflection staring back at me. He’d insisted that I was to be naked at the start of this scene, and that had filled my mind with all sorts of ideas about me going in some of his gear to be tormented. All of that went out of the window when I was confronted with…whatever this stuff was.

“Put your hand in it, pup” he replied. I knew that look in his eyes – he had something new planned for me, but he wasn’t going to let me know what. That look had been present before some amazing sessions with him, and I relaxed slightly – my nerves and uncertainty becoming less dominant as my horny side began to materialise.

He held the box in front of me, and I slowly moved my right hand closer to the liquid. Only now did I realise just how much I was shaking. I paused, and looked up at my Alpha once more. “You’ll enjoy this, I can guarantee it” he said, the look in his eyes somehow stronger than before.

In my hand went. The liquid was cold, slimy almost, but it felt strangely nice. It covered my hand entirely, but nothing else seemed to be happening. Was I supposed to use my hand to cover my body with this stuff? There didn’t seem to be enough of it to do that. I looked up to see my Alpha, looking slightly disappointed – clearly he’d been expecting something to happen.

“What..?” I started to ask, curious to know what I was supposed to be doing. The cold and slimy sensation felt like it was spreading up my right forearm. I quickly looked down at the box to see exactly that – the shiny black liquid was slowly working its way towards my elbow.

Startled, I instinctively tried to pull my hand out of the liquid, but it wouldn’t move. The liquid had passed my elbow now and was growing up towards my shoulder – the cold and slimy feeling against my skin was making me feel horny, despite the strangeness of what was going on.

“It’s liquid rubber – fully controllable by me”, my Alpha said, looking horny as he watched the shiny black substance as it grew across my shoulder and began to spread out across my chest and back. “It’s going to seal you in the perfect rubber suit so I can give my gimpy pup the treatment I know he wants and needs”.

Instant boner – hearing those words coupled with the feeling of the liquid rubber as it spread further down my back and chest – towards my groin was more than enough to completely defeat any remaining nerves I’d had and let my cock take over how I felt.

I lifted my left hand up in front of my face so I could see the last pieces of skin on that arm – the tips of my fingers – vanishing under the smooth, shiny rubber. “Fuck” was all I managed to say as my cock began to drip precum.

It spread up as far as my neck, but seemed to stop there. It came frustratingly close to covering my cock and balls, but stopped short, and instead spread down and around to cover my legs and ass. It sealed my feet as if I was wearing the most perfect-fitting rubber toesocks, but still my cock, balls and head remained uncovered.

I looked pleadingly at my Alpha – he was enjoying my frustration. I so desperately wanted my cock and balls to be sealed into the slimy-feeling horny rubber that now covered most of my body. I felt like I was ready to shoot my load just imagining the sensations as it spread from the base of my cock to the tip.

Lost in this thought, the cold feeling beginning to travel up my neck towards my head took me by surprise. He knew what I wanted the most, and was going to make me wait for it until the very end. The rubber covered my neck and face entirely, and for a few seconds left me unable to see or breathe. Panicking slightly, I was relieved when holes formed for my nostrils, eyes and mouth. It felt tight, but like on the rest of my body, not so tight that it was uncomfortable.

Finally, I got what I’d wanted so badly – I watched as the rubber slowly sealed my balls inside their new prison, before growing its way up the base of my cock, towards the tip (which was precumming even more now). I groaned in pleasure as the cold, slimy sensation travelled up my cock – I thought I was going to shoot my load before I’d even been played with inside this amazing rubber suit! I managed to hold back…just, as the rubber finally sealed itself around the tip of my cock to give me the tightest, best feeling sheath I’d ever worn.

Instinctively, I tried to move my right hand out of the now-empty metal box, towards my cock to have a proper feel, but I couldn’t. All of a sudden, the rubber around my right arm and shoulder felt tighter and thicker than the rest of the suit, restricting my movements and preventing me from getting anywhere near touching my cock, which was so desperate for attention.

“I told you”, my Alpha said, a smug look on his face, “it’s fully controllable by me – and now so are you, gimp”. Oh fuck! Why did that make me even hornier? “Have a look at yourself in the mirror”.

My body seemed to move by itself – the rubber on my legs almost pulling me to turn to the side and walk closer to the wall mirrors. Reflected there was someone I didn’t recognise – someone who most certainly couldn’t have been me. Not a trace of skin could be seen on the gimp standing there. His body was totally covered in the most perfect-fitting rubber suit imaginable: not a crease, seam or zip in sight. Even his eyelids and lips were covered by the blackest and shiniest rubber I’d ever seen. Only his eyes gave away the fact that there was a person trapped inside, and that the person was me.

Catching sight of my rubberised erect cock made me want to touch it again, but the rubber seemed to know what I was thinking – my arm didn’t move at all this time, despite what I was telling it to do in my mind. I’d never been so horny, so frustrated.

“I knew you’d enjoy it” he said, the horny look in his eyes reflected back at me as he stood behind his rubberised gimp. “You’re not finished yet though – there’s more I need to do to my gimpy pup before you can be fully used”
