Solo performer Saline explores the extreme limits of piss play in this intense solo scene. With a steel ball at the ready, she begins by stimulating her cock, building up a substantial load in her bladder. As the pressure mounts, she carefully inserts the metal object, her moans echoing through the room. She edges herself, teetering on the brink of release, before finally letting go, her piss streaming out around the foreign body in her bladder.
