Nao is my childhood friend. She has mature black hair and rather large breasts. Recently, Nao's development has been particularly remarkable... I, a shy person, can't help but take a peek. Whether she knows my feelings or not... Nao changes clothes in my room, pretends to seduce me by wearing revealing clothes, and confuses me with suggestive words, teasing me all the time. I'm happy and frustrated at the same time... I want to peek at her breasts, but I'm afraid I'll be made fun of if I'm found out... Oh well! I don't know what to do anymore! Please enjoy the naughty daily life of Nao and our exquisite (?) relationship.
