Kneeling on the cold floor, she feels the plastic bag crinkle beneath her knees. Her pussy throbs with anticipation, and as she lets go, a flood of piss fills the bag, the liquid seeping through and staining the floor. She moans, her large breasts swaying as she grinds her cunt against the plastic, relishing in the taboo act of wetting herself, the pee dripping down her thighs and onto the floor.
