A secret knock at the door reveals a brother's hidden desire. His sister, cloaked in modesty, lets him in, her cheeks flushed with shame and excitement. He's here to verify her purity, but as his hands roam her body, cupping her breasts, sliding down her thighs, they both know this is more than a test of her virtue. She's never been touched, never felt a man's hands on her, and as he pushes his fingers into her virgin pussy, she bites her lip, holding back a moan. This is their forbidden first time.
