Shounen ga Otona ni Natta Natsu 3

The protagonist, Ryuki Kirishima, started dating Kiryl. He remembers a strangely nostalgic scent. He lost his memory at the moment of climax during his last ejaculation. Ryuki performs exceptionally well in a soccer match. Kiryl watches him and calls him to the backyard to give him a reward. With the sound of others nearby, the two feel an intense thrill from the sense of forbidden excitement. Caught up in the moment, they almost get spotted by his teammates and flee to a flowerbed, where they find his childhood friend, Chiaki. Chiaki, openly hostile towards Kiryl, challenges her to a competition over Ryuki. The contest is whether they can pull off a "School Naked Blue○ Tour"! In broad daylight, each of them exposes themselves completely to satisfy their desires. What will be the outcome of this competition!?
