Aegigoe, Hitorijime Shite Iidesu ka?

"If you make too much noise, someone might hear you again." He said as he stripped her on the doorstep. Mayumi Hosaka, 28 years old. A career woman who works in Tokyo... sounds good, but she is a corporate slave and basically became a second virgin because of it. While browsing her smartphone before going to bed, Mayumi unintentionally visits an erotic site and decides to masturbate alone. The younger man who lives next door, Hayato Kuga, overhears her voice! He demands that she shows him how she looked yesterday and how she made that voice! But her body is getting wet from his gentle and forceful caresses.... Kuga-kun, why are you doing this...?
