This one was rare, she deliberately pulled down her pants, crawled to the edge of the bed, peed a lot, crawled back and pants up again.
Because this I recorded it, it was realy fun to see. Here you are for one time 
Did anyone understand what she said just before she decided to pee over the edge of the bed?
Edit: I watched the timeline after this moment, and the pee was never cleared. The bed has been used by also other girls, later the bed is used for some sex, and during that time they even lied with their heads right on the spot this girl peed, without even notice something.
