Betty's eyes flutter shut as she pushes her brother's massive cock inside her, her body trembling with religious guilt and taboo lust. The closet, once a sanctuary, now echoes with their desperate moans. Her brother's hands grip her hips, pulling her down onto his cock as she rides him, their bodies slick with sweat. With each thrust, Betty's guilt grows, but so does her pleasure, until they both collapse, panting and spent, in the close, dark space, their secret locked away, for now.
