[MKON-036] Aika Usaki who became a prey of the Way www-based Yarrisar group who was staying at the same inn on a school trip by a super serious she who never lets yara

This child is my girl, Aika Usaki. He has excellent grades and is a student council president. It's been a year since we went out with each other, but since we're so serious, we still don't let him do it, and we're made a promise that we won't do it until we're old enough to take responsibility for each other. However, H might certainly be good after becoming an adult. I want to spend more important time with Aika that I can only experience now. Aika was cuckaled by a strange university student on the school trip of one day which came to think so.
