One day, a woman named 'Nanao,' who works as a secretary for Shota's father, came to the house of Shota, who lives in a single-parent household. It seems she will be taking care of Shota while his father is on a business trip. Perhaps due to her profession, Nanao is a bit strict, and Shota, who has been curious about women's breasts since he was young and has never had a mother, starts an odd cohabitation life! The usually serious and beautiful secretary lets her guard down thinking he's just a kid, only to be drawn into Shota's pace, having her big tits groped and her pussy played with, ultimately leading to in-out sex... As the H pranks escalate, even the big-breasted secretary enters serious mode!
