There was a very pregnant woman waddling along the sidewalk. She had to be at least eight, maybe nine months pregnant. Roy wondered what would happen if he were to use the device to swap with a pregnant woman. Well, the best way to know what will it happen is just doing it.
He aimed the device to the woman, and switched with her. But... its screen said,
"ERORR - Unswitchable object selected. Reset object to the closest"
Instantly, Roy and fetus in woman's womb swapped.
He was confused about where he is. He couldn't open his eyes and everything was dark. There was full of some liqud. Even he couldn't even move. "Where am I? I switched with pregnant woman! Am I switched with fetus in her?" He thought. "Wait, then what happened to role swapper?"
