In the quiet of dawn, a sibling duo awakens, their shared room filled with an electric tension. The elder sibling, their body still warm from sleep, feels a familiar stirring in their loins. They reach down, their hand disappearing beneath the sheets, as they begin to stroke their morning wood. Their younger sibling, awake and watching, can't help but feel drawn to the scene. They tentatively reach out, their fingers brushing against the other's thigh, exploring the unfamiliar territory. The elder sibling tenses, then relaxes, allowing the younger to continue their tentative exploration. The room fills with soft moans and the rustle of sheets as the two siblings indulge in their forbidden morning delight.
