Hidden away in the dark, cramped closet, brother and sister give in to their forbidden lust. The sister, her eyes wide with fear and excitement, guides her brother's throbbing cock to her entrance. He pushes in, slowly, filling her tight pussy completely. She gasps, her hands clutching his shoulders as he begins to move, his hips pistoning in and out of her. The sound of their bodies slapping together fills the small space, their moans barely contained. The sister's fingers find her clit, rubbing furiously as her brother fucks her harder, faster. Their climax builds, their bodies tensing, until they both explode, their cries of release echoing in the closet as they cum together, their taboo desire satisfied, at least for now.
