Her brother, hearing her, can't help but investigate. Catching her in the act, he's immediately hard, his curiosity turning to lust. She notices, and instead of shaming him, she beckons him closer. They explore each other's bodies, their touch electric, their desire undeniable. He pounds into her, their sweat mingling, their moans filling the room.
