A hot gravure idol, a childhood friend who returned home in the sweltering summer, used the nymphomaniac techniques she learned in the city to bring this reclusive girl to orgasm. (Sasakura Aya, SONE-813)

I used to be a lively and charismatic leader, but I've been living a reclusive life since my parents' divorce… Meanwhile, my childhood friend Aya, with whom I had a close relationship, has matured after moving to Tokyo and is now active as a gravure idol… We're clearly mutually attracted to each other… “Yo, long time no see!” A familiar voice came from behind me. It’s Aya… Is it a mirage? Is it because it’s so hot that even my brain has gone haywire? “I haven’t fallen into depravity!” To my miserable state, Aya suggested, “Let me help you regain your confidence,” and then did a lot of erotic play she learned in Tokyo… This is the best summer vacation ever. Hooray!
