Frank's shower becomes a stage for a forbidden dance. His sister, caught off guard, stands there, her wet body quivering, nipples hard, and her pussy lips swollen. Frank, unable to tear his eyes away, watches as water drips down her body, tracing paths over her skin that his tongue aches to follow. The room fills with the scent of her arousal, mingling with the steam, as she struggles to keep her eyes on his, her body betraying her with every tremble.
