"Three and a half hours in a sweltering car, seven quid for a days parking, a thirty minute slog to a spot on the beach, a five minutes swim and now you're bored Jim?"

"Let's pack up and wander down the beach Rex. It's quieter there"

The sea lazily lapped the beach, the wet sand was cool and pleasant underfoot as the two mates wandered down the beach. Rising from the beach were jagged and crumbling cliffs. Pockets of vegetation interspersed the barren yellow clay cliffs and occasionally, muddy trickles of water made their way down gentle slope of beach to seep into the sand or form dirty pools.

Jim retrieved the sun lotion from the side pocket of his bag and sprayed his head. "I should have brought a stronger factor" he scanned the cliffs, but in the midday sun, they provided no shade from the sun.

"Maybe if we climb..." Rex stopped short, something had caught his eye. Directly ahead, the cliff was moving, something cliff coloured was moving down a gully. Two human forms, but only just recognisable, plastered as they were with mud. From head to toe, each was covered in a thick layer of clay. The guys stared as the apparitions made their way to the beach.

As the muddy pair approached Rex and Jim, their faces broke in to broad unabashed smiles. The shorter one glanced up at the deep blue sky and spoke "Hello there guys. Don't get burnt." he grinned pointing at his muddy coating "this is factor 1,000"

Leaving a trail of muddy splashes as they walked, the mud monsters made their way to sea to wash off, leaving Rex and Jim bemused and staring.

Two older, handsome fellas, now mostly clean waded ashore. Both bearded and heavily tanned, the shorter, broad and heavier set, the other lean with swimmers physique. "Down for the day?" The taller one asked. The two you're nodded, lost for words.

"The sun's just about to get its strongest" said the shorter guy. "You do need to be careful. I expect you'll think us guys a bit weird, but the mud is truly good for your skin and a coating at this time of day would be a good idea. Are you two guys up for it?".

Jim and Rex shared he briefest of glances then nodded enthusiastically "Hell yes" Jim replied.

They made their way to the cliffs. "Leave your stuff with ours", the taller guy instructed, pointing at a jumble towels, clothes and bags. "It will be safe here".

The cliff was about three meters high, carefully they climbed up, through the gully. The cliff was dry underfoot, powdery in places, stony in others, with the occasional ground thistle. Three meters up it plateaued out for a further twenty meters before rising yet again in steeper cliffs. They made their way to a tripod and then before them a pool glistening sharply in the sunlight.

Rex surveyed the scene. The tripod, battered and scratched had a GoPro mounted on the top. Footprints surrounded soft edge of the pool. The ground formed a lip over the glassy surface of the pond, through which little mounds of churned clay protruded. Rex approached the pool, tentatively. The ground gave way slightly and wet mud squished between his toes. Rex recoiled in distance and ran back to firmer ground.

Jim, who had now started burning, under the midday sun was more intrigued. "Go on, jump right in" the shorter guy urged. "It doesn't smell and it's warm".

As the camera rolled, Jim approached the lip of the mud pond. A moment's hesitation and JIm dived forward into the pond with a resounding splat. "What's it like?" called Rex. Jim let out an involuntary moan. "That's it. Roll around in it get good cover".

Jim rolled onto his back and enjoyed the sensation of the velvet wet mud that enveloped him. This was a new and amazing experience. The surface water churned with the mud to make an amazingly slippery liquid clay that felt like nothing else as Jim half swam, half crawled to the firm edge of the pond. He hauled himself out, a slimy coated mud monster and bounded over to Rex and his new found friends.

"Oh, yes, oh yes, that feels fantastic" Jim beamed enthusiastically. "Rex are you going to give it a go?"

"Buddy, I'm not sure I can compete with that display" Rex grinned at his muddy mate.

"I've got to try that again" called Jim as he bolted back to the muddy pit and against launched himself into to pond with an impressive splash. This time he dunked his head fully into the mud, eventually breaking the surface for air with a gasp which was half a moan of ecstasy.

As Jim lay their, face down in the mud, the older guy approached the edge of the pool and placed his hand firmly on the small of Jim's back. In the frictionless mud pond, with just one hand, he was able to push Jim forward, then back, forward then back and soon Jim got the idea and gently started pumping the mud, his hips raising and lowering rhythmically.

"Feels good doesn't it?" said the tall guy. Jim moaned the affirmative. "Let's get some pictures of you" called the shorter, stockier guy and with some reluctance, Jim once more crawled from the mud pond.

With his shiny coat of mud, completely covering his body, Jim felt exhilarated and all powerful. Rex grinned as he looked on at his friend. "If you want to use these pictures Buddy, you better adjust yourself".

Jim looked down and realised with horror he was tenting in the skimpy mud coated speedos he had on.

He looked at the camera and the others and realised that each one of them were sporting a semi, laying heavily in their speedo trunks. A muddy hand, down his speedos and he adjusted himself so his state of excitements wasn't so obvious, while he two older guys took pictures.

"You've got a big solid frame there Jim. I reckon it could take more mud" The four walked back to the pool and the two older guys scooped giant handfuls of wet mud which glistened in the bright sun.

Splat. Jims face received a handful of mud, then his chest, shoulders and back got a fresh coating of mud. Cautiously, Rex leaned into the mud pit and returned with his handful of shiny mud. Regarding Jim's muddy frame he knew exactly where to plant it. Splat, into the crotch. Jim's eyes widened as Rex rubbed the muddy load into Jim's stiffing shaft. Now the shorter guy was embracing Jim from behind and rubbing mud into Jim's chest, torso and tummy. Rex, eager to participate rubbed his muddy thumb across the top of Jim's cock as the to older guys continued to plaster Jim with fresh mud until all to soon, Jim's became more rapid and urgent.

Jim's cum spurted hot and wet through the thin fabric of his speedos, the one contrast to the layer of mud. When all four were spent, the two older guys led Jim and Rex to a pond of relatively clean water where the washed off much of the mud.
