I want a sister ⇐ Incest

[Anonymous]

I’m 17, my sister too. She’s a cousin, so I want this. How can I seduce her (I’m not talking about sex). There are shared secrets, sometimes it even seems that I am closer to her than her parents. Alcohol is definitely not an option. If I don’t drink much, my sister won’t even try for a long time (in this regard, she is less persistent and shy). Where can I start? Maybe with porn, but I just thought it was so blunt, maybe it would scare her off. But we never even touched on 18+ topics
