The Big Splash! is an explicit adult body-swap comic by KannelArt — one waterslide crash, and they trade bodies mid-pool.

Story: He ignores her screaming to slow down and they slam into the water together. When the splash clears, he is the one in her dark skin and long black hair — voice gone soft and wrong, red bikini top floating free while he gropes at a chest that is still swelling under his hands. Her tits and ass balloon past anything she ever had, heavy and glossy in the water, while she is stuck staring out of his male body, asking what the hell is going on. He does not know either — just that he is wet, hyper-stacked, basically naked in a string bottom, and looking at his own old face looking back at him.
