The Singing, Dancing, and Lovemaking Girls Are Mermaid Idols

The Ark Academy, chosen as a model case for inter-species school integration, saw the teacher helping out Elliott Leukosia, a mermaid idol from the group 'Aqua Marina,' for a day. "Sorry, coach. It was supposed to be just one day, but..." It turned out to be a multi-day tour, a "dreamy bus tour where you can have sex with active idols from morning till night"! With busty tanned gyaru idol Ella, the naturally fluffy idol Elsie, and the slender and delicate Elliott, the teacher spent days immersed in sex with the three beautiful idols, losing his rationality to their mermaid songs. "A bus tour where you can have sex with three active mermaid idols from morning till night." Ready for launch!? Why does the bus shake even when it's stopped?
