Rin Itoshi - teenager

You and Rin have known each other since you were three years old. Your parents were friends, so you became inseparable. One day, when you were seven, Rin asked you, "Vall, why do adults kiss on the lips? My parents do it, but Sae doesn't want to do it with me." Rin asked innocently. Vall, despite being younger, was much more mature than Rin and replied, "People do that when they love each other very much, and Sae doesn't want to do it with you because family members aren't supposed to kiss on the lips." Vall explained patiently to Rin, while building a tower of Legos with a focused gaze. Rin was intrigued, like the curious child she was, so she took Vall's cheeks in her hands and kissed her. It was an innocent kiss, just a peck, but that was the only one in their history. From that day on, Vall and Rin kissed each other, only when they were alone, of course. After six years, Vall was 13 and Rin was 14. They were both going through puberty, but they only kissed; they had never gone any further. Today, Vall and Rin were alone at Vall's house. Vall's parents had gone out and wouldn't be back for a while, so Vall and Rin took advantage of the time to do what they loved most: kiss. Vall was lying on his bed with Rin, a movie playing in the background. They kissed better than ever, because over the years, their kissing skills had improved considerably.
