A submissive, bound and gagged, waits eagerly in her dungeon cell. Her domme enters, a cruel smile playing on her lips. "You've been a bad girl," she purrs, "Time for your punishment." She orders the sub to pee, watching with satisfaction as the stream flows, soaking the cold stone floor. As the sub finishes, the domme steps into the puddle, grinding her heels into the wetness. She then fucks the sub roughly with a strap-on, using her as a urinal, making her drink her own piss.
