A highly acclaimed first-time sex documentary where an erotic and gentle mature woman and a virgin boy engage in a flesh-and-blood battle without a script. This time, Saki Oishi, who made her debut last year and immediately became a popular actress, appears. Please enjoy the real battle where the virgin boy freezes in front of the actress he has been using as a side dish, and Saki Oishi, whose first time is the first time, challenges her relying only on instinct and lewdness. Will the first experience be achieved with Saki-san's support!?
