The two friends Uchimura and his close friend often went to each other's house to study together, in order to help both of them progress and improve their academic results. However, that was only the initial purpose they set out, but when they put it into practice, it was completely different, not at all what they had thought. They studied little but fooled around a lot, without seeing any improvement in their academic results, but their sexual skills and passion increased rapidly. The beginning of this story was when the close friend unexpectedly opened the door and saw his friend watching porn and masturbating next to the little cute laptop. So all the thoughts of studying disappeared completely, replaced by the arousal boiling between the young man masturbating and the lustful girl at the age of curiosity about sex. Of course, a relationship that began with the following days inevitably took place.
