Sunao ni Narenai Bokura

Childhood friends Jun and Azusa get drenched in a sudden downpour on the way home from school.

The two of them rush to take shelter in Jun's house, where they each take a shower and change clothes with just the two of them there. In that situation, Jun notices Azusa's erotic charm as a woman upon seeing her lightly dressed in his old casual clothes, and he unknowingly gets erect?!
