Osananajimi de Koibito no Kanojo to Ecchi na Shitagi

Aki and Koharu share a bond that goes beyond childhood friendship, having grown together into a romantic relationship. One day, Aki discovers a set of alluring lingerie hidden in Koharu's room and playfully asks her to put it on for him. She agrees, and the two quickly find themselves swept up in an intimate moment. However, their private time is cut short when they realize they are running out of time before the school day begins, forcing them to abruptly halt their activities. With no opportunity to change, Koharu heads to school wearing the provocative undergarments concealed beneath her standard uniform. Throughout the morning classes, the lingering sensation of the lingerie proves to be a constant distraction, leaving her visibly flustered and unable to focus on her studies. Noticing her growing discomfort and flushed demeanor, Aki realizes she cannot endure the rest of the school day in this state. To spare her from further embarrassment and give them both a moment of privacy, he quietly escorts her away from the classroom and leads her directly to the school infirmary.
