One sister, noticing the other's flushed cheeks and heaving chest, suggests a game of truth or dare. The dares escalate into heated make-out sessions, hands wandering, breaths hitching. They explore each other's bodies, fingers delving into wet, inviting folds, until they're driven to the brink, panting and desperate for release.
