The sea conspires against him.

Despite the shallow water, both Lily and him were regularly splashed by the gentle waves. Getting salty water in your eyes wasn't enjoyable and it was distracting Lily about as much as the stranger pounding her butt. This made the hand job she was giving him rather sloppy. Her position made giving long strokes awkward and she had an unregular cadence from all the distraction. Worse, she was focused on the long shaft of his dick and hadn't yet touched the engorged head of it.

The water proof lube provided by the hotel was beginning to wash away with so much wiping in sea water. The stranger seemed to really enjoy Lily's ass, pounding her faster and faster. From her eyes he could see that the feeling was shared. He could do absolutely nothing from his position without falling into the water and he couldn't imagine being as blatant as the man and ask her to jerk him off better.

He suddenly felt something weird. The man was grunting, obviously very close to cum, but something weirder was happening. K-T quickly realized that they suddenly were laying on wet sand rather than in the water. He turned his head on the left to see where the water had gone and could only hear the moan of the man blowing his load in Lily's ass just before a massive wave rolled on them.

He was rolling on himself, underwater for a while, not knowing where he was and his lungs burning for him to take another breath. When his head surfaced he saw that he had been washed away nearly 30 feet from the shore. The cristalline water was now troubled by sand, kelp and debris, probably scrapped from the bottom of the see by the wave.

He was glad to see that Lily was swimming towards the beach, halfway from his distance and for all he cared butt-guy seemed to be ok. He swam back towards the beach too, there was no trace of his shorts (he realized that he couldn't even remember going on a beach without losing his swimwear or not having some to begin with.). He'd have to stay naked until they went back to their room and he had already begun chipping away at his wardrobe on his first day on the island.

All those considerations stopped when barely to the point where he could get up and walk his way back rather than swim, he was struck by an intense pain. It was like been touched by a taser or being burned. And of course it had happened to the long shaft dragging under him like the keel of a boat. He let go of a scream of pain. After a few seconds the pain didn't dull but it was worse, he know felt like someone had cut his dick and balls with a red hot knife.

In his panic he saw what had happened to him. The wave had dragged an enormous jelly fish on the beach that was usually safe and his dick had got entangled in the venomous tendrils flowing behind it.

He rushed to the beach, his frantic moves had broken the tendril and his speed in the water had washed it away, but when he fell on his back on the sand of the beach it looked like someone really bored had doodled on his dick and balls with a thin red sharpie.

"Help, I've been stung by a jelly fish, it burns so much," he screamed. He could hear the whistles of what was probably a lifeguard rushing in after such a big wave had struck the beach.
