The final round was to be head to head. Having cleaned up from the last round, Sam and Brandon were lead out onto stage shirtless and wearing loose basketball shorts. They were each told to stand in a large-ish tub each, either side of a gunge tank. A huge vat of multicoloured gunge was wheeled out onto the stage; three large clear hoses snaked out of the bottom.

The final game is one of strategy and luck, explained Christ, to the crowd below. In this vat we have 140 litres of gunge and three hoses, one of the hoses leads to the vat above the gunge tank, as for the other two, there will be one down each of your shorts. The game will work like this, in each of the 12 rounds there will be a certain number of litres in play, if you win the round, you get to choose which hose to send the gunge down, you can either bank the gunge in the vat above the tank, or you can send it down your opponent's shorts to try and fill the tub they're standing in. The loser is the first person whose tub overflows first, or whose tub is the fullest by the end of the game. But be careful, each tub has a capacity of only 30 litres, so if you don't bank enough in the gunge tank, the loser will get away lightly, and there will be wasted gunge left in the reserve. Does everyone understand?

Yes, they both replied as they grinned at each other across the stage this was the final showdown.

There are 12 rounds in total, and the contest couldn't be simpler paper scissors rock said Chris, tucking a hose into the top of each of the boys' shorts, there's 5 litres of gunge on the line for each of the first four rounds.

Let's begin!

Brandon took out the first two rounds, banking the gunge in the tank for the loser both times. The think multi coloured mess snaked its way down the hose and into the awaiting tank.

Sam, however, won the third round and didn't hesitate to send the gunge Brandon's way. Brandon could only watch as the gunge crawled its way across the stage and down the hose, before pouring through his loose shorts and onto his feet. When Brandon won the fourth round, he didn't hesitate to return the favour to Sam.

For the next four rounds, the stakes are raised! Announced Chris, 10 litres are on the line

The guys were still surprisingly clean, the shorts weren't an effective trap for the gunge which poured down their leg to squelch around their bare feet. However, without underwear to hold them back, both Sam and Brandon were pitching impressive tents in front of the audience.

Brandon's luck continued to fail him, and he lost all four of the next rounds. Sam banked the first three lots of gunge, before once again sending a torrent down Brandon's shorts.

The final four rounds! announced Chris with excitement, the boys have banked 50 litres of gunge so far, but there's still 80 left to play for it's anyone's game and each round is now worth 20 litres! This is where the strategy comes into play

The next round went to Brandon, and he sent the gunge gushing down Sam's shorts. Both boys' tubs were now at least half full and Sam's was just about nearly overflowing already. With 20 litres in play each round, a win in any round would be enough to overflow the other's tub. Brandon won the 10th round too, but banked the gunge in the tank he wanted the loser to get a decent drenching. Sam was obviously of the same opinion because he too banked the gunge he won from the 11th round.

This is edge of your seat stuff folks! said Chris, we've got 90 litres waiting for the loser, and it's anyone's game! And with out two very excited contestants, he added, gesturing to the bouncing tents that were the Brandon and Sam's shorts, this game is coming down to the wire.

Brandon took a deep breath, composed himself and squared off against Sam for the final round. Looking down at the half full bucket of gunge swirling around his feet he held out his fist for the final round.

1 2 3 Paper

He looked up, and there was Sam with a smug smile on his face and a pair of fingers held out like scissors. He'd lost.

Sam stared at Brandon directly in the eyes and with a triumphant smile said, I'd like to bank the gunge thanks Chris.

For a moment Brandon didn't understand. And then, as the final dose of gunge made its way to the vat above the tank, he realised. The true prize was not the victory, it was being in the tank. Since Sam's tub was fuller than Brandon's, Sam had lost, and Chris was directing him to take off his shorts as he seated him in the tank.

As the winner, it was Brandon's privilege to pull the chain and gunge him. Sam sat under the enormous vat of multicoloured gunge, his hard cock and naked body on full display for the raucous and horny audience. Brandon stared at Sam's wide eyes and quivering body, unsure whether it was because he was fear or excitement that he could see. The only thing he knew for sure was that he was filled with jealousy.

Still holding the chain, Brandon stood in front of him, partially blocking the audience's view.

Be sure to look up, he said.

And, as Sam did so, distracted and waiting for the gunge, Brandon slipped off his own shorts and sat on Sam's lap, facing him. Sam's wide eye were suddenly wider still as he felt his cock slide up inside Brandon, who looked back with an enormous grin on his face.

Now this is a prize, said Brandon as he pulled the chain. The thick streamers poured down over the two young men, sticking instantly to their hair and bodies. Brandon grinded against Sam crotch and kissed Sam strongly as Sam grabbed at his hot, slipper cock and endless streams of warm mess poured over their naked bodies.

Chris, for once, was speechless.
