MKON-036 Aika Usaki, a very serious girlfriend who would never let me have sex with her, fell prey to a group of sluts who were staying at the same inn on a school trip.

This girl is my girlfriend, Aika Usaki. - He has excellent grades and is the student council president. - We've been dating for a year, but he still won't let me have sex with him because he's so serious, and we made a promise that we won't have sex until we're both old enough to take responsibility. - But maybe it's best to have sex only when you're an adult. - I want to spend more precious time with Aika that I can only experience now. - One day, on a school trip, Aika was cuckolded by strange university students.
