Brazilian sisters, curious and adventurous, discover the thrill of "Pau duro" - a secret world of self-pleasure. They timidly start, fingers tracing their young bodies, exploring new sensations. Whispers fill the room as they share their discoveries, their voices echoing the rhythm of their movements. The tension builds, their breaths syncopate, and suddenly, they're no longer just sisters, but co-conspirators in a dance of self-discovery.
