Through an accident/drunken confession/sexytimes, it's discovered that our heroine can squirt, except she doesn't like it as she loses control/it's so powerful/whatever. However, her partner finds it extremely hot and decides that this must be explored. At great length. So he ties her up and ain't letting her free until that bed is soaked through. She loves every minute of it.

Open to any male, and I do mean any – hell, if you want to make my ladyboner go wild, make it our favourite heartbreaking dad, James.
