A brother's curiosity piqued by rumors, he demands proof of his sister's purity. She reluctantly agrees, her face flushed with embarrassment as she lowers her pants, revealing her hairless, untouched pussy. He runs his fingers along her slit, feeling the tightness of her virgin hole. She winces as he inserts a single digit, her hymen stretching taut. He pushes further, breaking through the barrier, and she cries out in pain and pleasure. Their breaths come in ragged gasps as they continue their forbidden exploration, their bodies pressed together in a dance of innocence lost.
