In the confines of the bathroom, she indulges her taboo desire. The toilet, her stage, she sits, her large form trembling with anticipation. Her bladder finally lets go, a torrent of warm piss flooding the bowl. The sound, her own wetness, it's all too much. She can't resist, fingers delving into her soaking pussy, rubbing furiously as her piss continues to flow, filling the room with its heady scent.
