Molhadinha, her heart racing with excitement, continues her forbidden solo session. Her fingers plunge deep into her tight, wet cunt, fucking herself hard as her brother watches, his cock straining against his pants. She pushes her fingers in and out, her moans filling the room. He can't help but imagine his cock replacing her fingers, pounding into her tight pussy. She can see the desire in his eyes, matching her own. She leans back, spreading her legs wider, inviting him in. He hesitates, then steps closer, his breath ragged. Just as he's about to give in, their mother's voice echoes from downstairs, breaking the spell. They both freeze, their faces flushed with guilt and unfulfilled lust.
