Manny dipped his toes in the water, and as Margaret and Andrew came to watch, the tf began.
he saw his feet swelling up, like a balloon.
suddenly, with a sudden pop, Manny gasped. his feet had became webbed!
on his feet his toes had webbing in between,
and his toenails were nowhere to be seen.
Manny touched the webbing. it was soft, cold, and gelatinous, and translucent blue.
Then, Manny's legs were involuntarily drawn together, and his feet flattened and spread out. His feet blended together, and he could no longer separate his legs. They had joined together and become as one. The man watched as his shorts were torn apart by the changes to his body. He watched as what had been his legs extended another full meter beyond where his feet should end, and a fish tail unraveled itself. Scales appeared along the tail, thousands of them, all tinged dark blue, with a few lime green streaks here and there. His torso had not gone unchanged. He felt his privates recede behind a flap of skin, so it looked as if they had never existed.
Intuitively this led him to lift up his vest, and look at his midsection to discover exactly where man met fish. The transition was surprisingly difficult to find, it was gradiated between several inches. In fact, Manny couldn't view and recognize both sides at the same time, it was too much of a blur. What were scales on one side slowly became the goose bumps he saw earlier, then a few freckles on human skin.
He seemed like a single unit, there was no longer any distinction in his eyes. The tail was a part of his torso and his torso was a part of his tail.
Manny had transformed into a merman.
