A girl has sex with a bunch of guys, but she only pokes a hole in one condom and mixes them all up so no one knows who got her pregnant.
My sister got pregnant by her crush, but she made it look like it was her brother.
My friend got pregnant by her boyfriend, but she made it look like it was her best friend.
My cousin got pregnant by her crush, but she made it look like it was her crush's best friend.
