Maiden Harbour Academy is an outstanding institution where a diverse range of students gather. A request from Elior, a mermaid residing in the school, led a teacher to temporarily join her idol group, Aqua Marines. "I'm sorry Coach… You know it was supposed to be only for a day..." However, as days passed during this tour, they found themselves in an erotic bus tour called 'Actual Idols Enjoy Pleasure from Morning Until Evening'. This included busty brunette Eera boasting about her big breasts, natural airhead Elshi, and slender Elio tirelessly serving them sensually. As he spent time with these three beautiful idols, this teacher got entranced by the siren song of the merfolk, slowly losing control of his rationality. A Bus Tour Full of Actual Mermaid Idols Having Sex All Day Long?!? OMG!!! Was that tour still paused but felt like things were moving???
