This time I bring you one of my favorite 3D animation of all time, in the PMV/HMV form!

It's the work by Almond Collection: " Panty pilferers and mermaid in school swimwear パンツ泥棒とスク水マーメイド"

Since Almond Collective doesn't have official site, so I can't link anything here. But search up the name above, you'll find it somewhere.
