definitive sibling relationship watchlist
Anime
(the following reviews may include spoilers)
also KEEP IN MIND: many of these are appropriate for adults only!
stories of siblings being more than just siblings with one another as a main focus in the series (not necessarily romantic, though a lot of these are). everything goes from mild brocon/siscon to almost hentai. (no actual hentai is included.)
these anime are organized roughly in order from most wholesome to most perverted. i also include a short synopsis of each one along with some useful info, hopefully it can be helpful in picking a new show to watch. just keep in mind that not all of this is worth watching, i just want to give you all the options.
i only included the main entry [with one exception, for good reason] if a series has multiple seasons/ovas/movies etc. (no stacking the list with random ovas here!)
ALSO NOTE: this list is under construction, all the entries at the bottom without a synopsis i have yet to watch and categorize.

a wholesome story about twin sisters working together to make their dreams come true through high school. there's a love triangle aspect that isn't very good imo but otherwise it's a nice story.

a sci-fi magic show with a very OP main character and his sister who is a huge bro-con; it's implied the affection flows both ways. the sci-fi battles and lore are fun, and i'd recommend watching the prequel (reminiscence arc) to get a better idea of the why and how of the siblings' relationship.

a girl's adopted sister disappears one day and, because of her crush on the sister, she goes on a grand fantasy adventure to try to reunite with her. keep in mind that if you're watching solely for their relationship there is a fair bit of filler content not related to it and the ending is fairly sad. still a very interesting adventure.

there's not a lot to it, other than two stepsisters with an intense desire to pleasure their younger brother. the underlying story isn't too important, as you're probably here to see the perverted ways in which they express their affection.
