Brazilian sisters Aninha and Xaninha, always close but never crossing boundaries, find themselves alone one afternoon. Boredom and curiosity lead them to explore each other's bodies, fingers tracing sensitive curves and lips tasting forbidden fruit. They tease and pleasure each other, their moans filling the room, until they're interrupted by a sudden knock at the door. Panicked, they quickly dress, hearts pounding with a mix of fear and excitement, leaving their newfound desires hanging in the air.
