Ore no Imouto ga Konnani Kawaii Wake ga Nai, Nisemonogatari Recommendations
Similar older brother themes. As an older brother myself, I can relate heavily to both of these. Both of these (and Bakemonogatari) are in my all time favorite shows.
Anime that focus on the interactions between older brothers and younger sisters. These would be enjoyable especially to those of us who are in fact (responsible) older brothers in real life.
*Watch Bakemonogatari first before starting Nisemonogatari.
Self-proclaimed sister haters that would sooner die then let them get hurt.
