It is a sexual intercourse with children who experienced in their parents' hometowns when they returned to Japan during the summer vacation. After having had sex with me for the first time a year ago, sona and yukari got a little grown up, but they were still two cute people in lollipop, poor milk and pie bread. A deep kiss and a kind love affair that interacts with two people during the absence of an older brother, plenty of inside out in the mark of affection.
