The closet, once a sanctuary, now pulses with a carnal energy. The sister, dressed in a modest gown, sinks to her knees, her heart pounding like a drum in her ears. Her brother, his cock straining against his pants, watches as she tentatively reaches out, her small hand wrapping around his thickness. She looks up at him, her eyes filled with a mix of fear and longing, before taking him into her mouth. The room fills with the sounds of wet, sloppy sucking, their bodies pressed close, their breaths mingling in the stifling heat.
