Looking for anime from Netflix?

On Netflix (at least I think) there was an anime that I can't find anymore. I also only saw 1-2 episodes.

The first episode was such that mainly women ("waifus") were lying or swimming in a swimming pool by the pool, all in bikinis.

There was only one "boy", believe the brother of one. And that was just a bit sexual the whole time, so ecchi-like.

In general, it was a lot about everyone hanging out by the pool and lying around or something. Does anyone know what? (It's not Grand Blue, the characters are all rather youthful / young)

Undefeated Bahamut Chronicle?

Unfortunately not that similar in style, I think it's more about school teenage stuff.

Are they in the pool for the whole anime or are they some episodes? In that case it could be Date A Live.

Yes, rather the whole episode: -D Date A Live is unfortunately not either, but definitely in the same style.

I haven't seen anything on Netflix in a while, so if that's a new one…

I can think of Rakudai kishi no cavalry.
