Watch Ronica take a nice, relaxing, bath in this video.  But only after she pees in her pants first.

We join Ronica in this scene as she is preparing to take a bath.  She enters the bathroom, starts drawing the bath, and waits for the tub to fill.  As she waits, she grows ever more desperate to pee.  The tub filling with water, and the sound of the faucet, conspire to torture her bladder.  Eventually she gives in and pees in her pants.  Once the tub is full, she steps in, still wearing her pee soaked clothes.  In the tub, and fully drenched, she slowly undresses, then masturbates.
