In the quiet of their home, a brother and sister stumble upon an unspoken connection, their gazes lingering a little too long, their breaths a little too heavy. Their curiosity piqued, they explore each other's bodies with tentative fingers, first on the outside of their clothes, then, as desire grows, beneath. She discovers his hardness, he feels her wetness, and they're both drawn to the forbidden fruit they've found in each other's arms.
