Another series, which means what do we call the pool? Cause, making something coherent out of Google isn't something I wanna do.

The common element in the image titles is "見えそうで見えない", which means something like "Seems like you could see it, but you can't" or "Seems visible, but isn't". Basically, you'd think you'd get a flash of underwear, sideboob, or similar based on the poses and outfits, but you don't.

Good enough for me.
