What is the source of the video showing the girl in the blue one-piece swimsuit?

Saw this video on tokyomotion.com firstly, but the link of this video doesn't work anymore, this photo is from the video cover. The title of the video is スク水アへ顔. I think it looks like a Japanese amateur works and I've been searching keywords スク水 on FC2 but ends up with nothing. The key is the swimsuit the girl's wearing is a blue halter-neck swimsuit which is very different from regular スク水(swimsuit) in many other Japanese videos.
