Wash yourself out

You find yourself a space and fill a washbasin with some water you've kept from a cistern. Standing with one foot on a low stool, you push two fingers inside yourself. Seed begins to wash out of you, the result of letting someone inside you this very day. It pools into the water in thick, peraly strands, as you scoop and rinse, again and again, trying to remove as much as possible.

When you're done, the washbasin is a subtle white. It should be enough, right?
