Eddie decided he had some time to relax for a while.
Thankfully, he lived right near a small shore, near a uninhabited beach leading to a river mouth.
So Eddie changed into his bright red swimming trunks, and went outside.
He went to the edge of the shore, and dipped a toe into the water.
"Looks good for a dip." he said, hardly noticing his foot growing an incredibly small and unnoticeable bit in size.
Eddie took a deep breath, and waded into the ocean, up to his middle. He didn't go too far out, just far enough to a part that was just deep enough to submerge himself.
As soon as he stopped, he grew a little more in size. And he hardly noticed his size. But he did seem to notice his trunks were tighter than normal.
Holding his breath, he dives Underwater.
Unbeknownst to him, Eddie started getting bigger and bigger, more and more.
When Eddie came up for air, he gasped, upon seeing how tall he was now.
And then, he kept on growing.
"Oh my!" Eddie exclaimed, upon seeing his body expanding. "What's happening to me?!?"
Suddenly, he heard cloth ripping - his bright red trunks were now too small for the growing man, and immediately, they were split in two.
Eddie watched as his naked body grew bigger and bigger still.
