/jp/ - Otaku Culture

So I haven't played any VNs in a LONG ass time, but suddenly feel like getting into them again. I prefer nukige as I am not motivated to play VNs without nudity or sex.

I am well aware of VNDB, but I get so confused as to which to actually try to play, so I would prefer suggestions directly form /jp/ers.

What I am looking for:
1) Prefer it to be in Japanese and not English
2) I am looking for any good nukige with any of the following major themes in them: loli/futa/yandere/sisterfucking

Ideally I want all 4 of those themes in one game, but I doubt it exists.

Finally, with suggestions, and since I've been out of the loop so long, I need to know where I can actually get the suggested VNs (in Japanese). Also I don't really want to buy them so I need to know where I can pirate them.

Pic related, it's the last VN I played and enjoyed, and I played it when it was brand new, so yeah it has been awhile. I should also add I like dark/sad story stuff, but happy school romances are okay too.
