Jun meets a man at the station and sets off on a trip together. The man is instantly captivated by her breasts and can't resist groping her roughly on the train. Later, they go for a drive with Jun behind the wheel—her first time driving in a year, though she manages to reach the SP apartment safely. At the mixed-gender bath, the man is mesmerized by her big tits, playing with them freely. Jun washes his body using her breasts. After soaking in the bath, they sip sake together, teasing each other's nipples, then attaching vibrator clips to her nipples. The intense vibrations make her writhe in pleasure—this journey has only just begun.
