What, was she swimming naked, holding her vagina open, waiting like an idiot for the magical undying sperm to enter? If you have to make up a pathetic story like "a swimming pool deflowered me," why not just go out and get an abortion to hide the entire thing? That way, only the girl and the abortion clinic would be the only ones to ever know about the pregnancy. The mother has to be the most gullible lady in the history of history.
