>>6222530Alright, from a rather normal perspective here, and my years on 4chan
I've seen tons of wincest threads. To be honest, troll or not, I've seen a ton of "femanons" post in said threads saying they're in love with their brother, never actually dated, but some would occasionally see their brother in a romantic way. One stood out, she sees her older brother in secret maybe about once a month and they went on a great romantic date in a far away town so nobody would know them, wound up making out in public and fucking in private. Seems like what you should shoot for, OP.
My advice is to keep the momentum going. The above is your goal. You should suggest to her that each week you two go out and have fun just the two of you. Each week, if you miss a week then no problem. One day, just you two, for a fun night. If she agrees, take her to things that a brother might not take a sister to. Romantic dinners and movies, picnics, etc. Something intimate. Constantly be flirtatious. If she agrees, up the anty each week. Keep flirting online/txt to a very minimal, no more than one or two a day unless you have a conversation. Maybe if she wears an outfit that drops your jaw, mention it to her via facebook message. Nothing pervy, just a "you looked beautiful in that dress, FYI".
