Rica, the older sibling, has always held a secret power over her younger brother. Today, she decides to indulge in her favorite pastime, using her mouth to bring him to the brink of ecstasy. She starts by gently sucking his tip, flicking her tongue over the sensitive head, before taking him in fully, her gag reflexes non-existent. She expertly works his length with her mouth, her hand cupping his balls, her saliva coating his shaft, creating a lewd, slurping symphony as she bobs her head, her brother's moans egging her on.
