This first-person JOI scenario uses binaural ASMR dirty talk as mischievous adult cousin Waka returns from school in the city. She has grown prettier but remains carelessly revealing, and when she catches him masturbating to secretly recorded footage of her underwear, she demands a closer look. From then on, her erotic whispers keep him hard while she watches and toys with his cock whenever she pleases. Her countdowns even dictate the exact moment he ejaculates, leaving both his cock and pride completely under her control.
