School trip. For the popular kids, it's the ultimate divine event. But for the introverted boys, it's a hellish event where they have to watch couples flirting and are left out of group activities... But this year is different! Our school has finally introduced unlimited sex on school trips! Thanks to this plan, we introverts have a ray of hope! It's the best! We, who were destined to be virgins forever with no connection to love or romance, can now have sex to our hearts' content. And the partners include the girls we're interested in in class, and even popular girls from completely different worlds whom we've never even spoken to before! It's amazing! Plus, female teachers are also allowed to be penetrated! So we can experience the bodies of adult women! Sleeping is a waste of time! Rather, I want to stay in the inn and just keep fucking! Tourist spots? Shrines and temples? The pussy in front of me is a national treasure far more valuable than any of that!
