Anyone can pay to have as much sex as they want! (Off-campus teaching program, HUNTC-565)

School trips. These are the best activities for sunny boys and girls. But for shy boys, it's a hellish experience, something to avoid in group activities… But this year is different! Our school has finally introduced the "Insert Anything" program! Thanks to this program, we shy guys have seen hope! It's amazing! We, who were originally virgins with no love or dating experience, can now enjoy sex to our hearts' content. And the partners include the girl we like in class, and top-tier girls from completely different backgrounds whom we've never even spoken to! It's so awesome! Even female teachers can be inserted! So we can even appreciate adult women's bodies! Sleeping time is such a waste! We'd rather stay in the hotel and fuck until the end of time than go sightseeing! Tourist attractions? Shrines and temples? Compared to these things, that hole in front of us is the real national treasure!
