Make a vividly detailed BBC Merlin story with Merlin, who has a crush on King Arthur, and King Arthur deciding on skinnydipping to relax after a long day. Soon, they're both in the buff as they're entering a swamp pond near Arthur's home (compliment Arthur's hair, butt and physique, compliment Merlin's butt and physique). Describe how Arthur looks as he relaxes so much that he lets out a fart into the water, enjoying the relief. Merlin was just happy to see Arthur feeling good. Moments later, a few dead fish begin rising upwards, killed from the men's fart stench. They collect them and cook a meal using them. Add dialogue throughout the story from start to finish
