Here's perhaps my idea of an ultimate male gunge fantasy:

Logan and I sat down on the bench and rolled our jeans up. I glanced across at his dark brown hair and briefly glimpsed his hazel eyes. He gave me a quick smile. We were sitting backstage in a bizarre tv show for an adult cable channel; having been pulled out of the audience.

We pulled off our trainers and socks. I caught of glimpse of his perfect, soft bare feet before he slipped the pair of black rubber boots he was given on. I pulled my boots on as well.

We were led to a small, tiled white room. There were two plastic chairs built into the floor facing each other less than a metre apart. Above each chair was a large pipe with an opening that pointed at the chair below. There was also a single small clear flexible pipe that hung from the ceiling with its other end lying on the floor. There was a flush chain that also hung from the ceiling next to each chair.

We were ushered to the seats and the door closed. We sat there facing each other, tips of our welly boots touching. I was quite turned on by the sight of Logan in rubber boots.
An electronic voice came on and told us we'd have to play a game against each other. The loser would be punished.

Logan flashed a cheeky grin at me.

The voice asked me the first question. I got it wrong. Logan got his question right. I got my second question right, and Logan got his wrong. We were even. Then I got the final question wrong. Logan made a nervous face as his question was read out. He got it right.
Damn I muttered.

The voice instructed me to put the flexible clear pipe into my pants. I did as it asked, pushing inside the front of my underwear in my jeans.

The voice instructed Logan to put his boots on my legs. He lifted his feet up and lay his booted feet on my legs, toes pointed outwards. I immediately was turned on.

I was instructed to pull the boots off.

Slowly, I pulled Logan's left boot off, revealing his perfect barefoot. I playfully rubbed his foot, and he laughed. I rested it back down on my leg and dropped the boot to the floor. I then pulled the right boot off. Logan's two bare feet were laying on my legs.

Logan was starting to cotton on to what he should do. He put his bare feet together, and rested them in my lap. The heels of his bare feet were resting against my crotch, his toes up against my t-shirt. I had a massive hard on, and he could feel it through my jeans.

He didn't seem to mind, and instead flashed me a cheeky, nervous grin.

Now its time to flush him Logan the voice boomed out.

Logan reached for the chain hanging next to him. He held it in his hand, looked me straight in the face and cheekily said enjoy as he pulled the chain.

Thick green gunge began shooting into the clear tube from the ceiling. It snaked its way down, suddenly spilling into my pants. Oh God! I exclaimed. It was cold, thick, goopy.

It kept coming. My underpants were being filled with the green goo.

Logan took the opportunity to push his heals into my pants. His soft feet smooshed the gunge around and caressed my crotch.

I stared at him with wide eyes and could barely control myself. I put my hands on top of his feet, and felt them squishing the slime around my crotch. I could tell Logan was having fun torturing me, and he could tell I was incredibly turned on by it. His feet felt so good.

I reached for my own flush chain, not sure what it would do. I yanked on it. Suddenly, then green slime began pouring all over both of us. It sprayed everywhere. Logan, surprised, let out a yell. His nose wrinkled up as his face formed a look of shock.

The souls of his feet squished harder into my crotch in surprise. They were also getting covered in green gunge, as it fell all over me. He was also getting totally covered, pouring down his hair, over his shoulders, spattering in his lap.

I was surprised by the sudden pressure his soft feet applied. I exploded in my pants. He couldn't tell, as we were getting showered in green goo.

Wow I exclaimed. He laughed, and stuck the gungy sole of his foot into my face. I think he realised I had really enjoyed the experience, though perhaps not how much.

The door opened, and we were free. We squished back to our seats, with the other audience members looking at us. Logan, barefoot; me still in my boots; both of us totally slimed.
