A brother's pride, a sister's curiosity, and a BBC encounter they'll never forget. When she stumbles upon his hidden stash of explicit pics, she can't help but ask. "Is it... really that big?" he smirks, leading her to his bedroom. He pulls out his throbbing, thick cock, her eyes widening in disbelief. She licks her lips, eager to taste the BBC she's only heard whispers about. He guides her head down, his hands tangling in her hair as she takes him in, inch by inch.
