I want to do the deed with my sister

Recently, I’ve had sex fantasies about my little sister and even had dreams of her having sex with me. I often search and even try to find out how to have sex with her but actually don’t act it out as I’m not brave enough to do so. We both live in the same house and I always want to try to do the deed but never actually act it out like I said just now. I want anyone with a history of incest or done incest before to give me some advice on how to. I’m still a virgin. Btw I’ve seen my sister naked tons of times already and I always get horny. I have no idea whether she has the same feeling for me too. I’ve also caught her trying to masturbate and talked to her about it. I might sound weird but I just want to have sex with her.
