The confined space of the closet amplifies their heartbeats and the scent of their arousal. The sister, her modest dress hiking up, feels her brother's hardness pressing against her. He, in turn, can't help but notice her nipples tenting her bra, her breath hitching as she tries to maintain some semblance of control. Their hands, tentative at first, begin to explore, finding pleasure in the forbidden fruit. The world outside fades away as they lose themselves in their sinful, yet exhilarating, newfound intimacy.
