A willing submissive, his eyes downcast, crawls on all fours, eager to please his Mistress and her guest. His hands are bound behind his back, his movements restricted to his knees and hips. He can feel the cool air on his bare, exposed ass, a reminder of his vulnerable position. His Mistress, resplendent in leather, watches with a smirk as he approaches her guest, a dominant woman with a commanding presence. The submissive's destination is clear: her guest's crotch. He can smell her musk, a heady mix of arousal and power. She unzips her pants, revealing her hard, throbbing cock, and the submissive eagerly leans in, his tongue flicking out to taste the precum beading at the tip.
