In the dimly lit living room, a brother and sister find themselves alone, their parents' absence stirring an unexpected tension. The sister, wickedly curious, starts to touch herself, her moans barely audible. Her brother, noticing the unusual sounds, investigates and catches her in the act. Instead of outrage, he feels a primal urge, his cock hardening at the sight of her naked body. They lock eyes, the air thick with unsaid words, until she finally breaks the silence, "Fuck me, like you've always wanted to."
