KURARA stared intently at her brother's young male friend. The man sat in seiza, appearing timid and nervous. When her brother ordered, "Suck his cock," the man shyly pulled down his underwear. KURARA decided to obey her brother's command. Slowly taking him into her mouth, she felt him tremble softly with a quiet moan. How was her brother feeling about this scene? Seeking an answer to that question, KURARA moved her tongue in rhythm with the man's motions. Eventually, he climaxed inside her mouth, exhaling deeply. Afterwards, her brother gently wiped her lips.
