Aki Kurotsuki, who had her first experience when she was in the lower grades of elementary school, grew up smoothly (?!) into a perverted girl. Aki-chan is a genuinely erotic and perverted girl. Even when masturbating, she is a pervert who thrusts her fist into her anal and does not stop until she cums! The only way to satisfy her is to skewer the fist into her anal! !
