The doctor did every check-up imaginable as you sit there, while the lifeguard that dropped you off waited there. You had to show reflexes, your pulse, and your heartbeat, while at the same time, the doctor looks inside your mouth, your ear, and your eyes. All signs of vision were normal, but there was one last thing to check.
"Please show us your privates," the doctor says, causing you to blush. You then do what she says, and close your eyes, while revealing your privates to her, and the lifeguard. The lifeguard herself was speechless after seeing it, as the doctor scooted away. "Is it bad?" You ask. "I'm afraid it is," the doctor answers. "You have the mermaid virus." You gulp just after looking, and find that nothing was left of your privates, except for a pair of lips that resembles that of a woman's privates.
