A sister's playful curiosity leads her to explore her brother's intimate secrets, finding a collection of explicit selfies. Fascinated by his smaller than average endowment, she decides to give him a unique 'gift'. Waiting for him to return home, she prepares a seductive show, stripping down to her underwear before finally approaching him. "You're so small," she whispers, "let me make you bigger." Taking his soft penis into her mouth, she begins to suck, using her tongue to trace its length, determined to bring him to his full potential.
