As a college student, I decided to go back to the countryside for about a week during the summer vacation. There I met a little older 'Mai' who lives in the neighborhood for the first time in a while. She used to play with me a lot in the past, and she's grown up now. Noticing that gaze, Mai-chan begins to seduce by showing off the valley. I couldn't put up with her sensual feeling...I started rubbing her milk, licking it, and even joining her... While returning home, I earnestly sought that body.
