Need some advice. ⇐ General

In general, the story is like this. As a child, my sister and I were intimate orally. She showed herself without hesitation, I kissed her ass and pussy. Cousin. I was 5-7 years old, she was 5 years older than me. Now she is 49. There is no way to tell with her husband. I’ve always been a blast in the normal sense of the word.
This summer I came to visit, when we were saying goodbye at the station, she kissed me ambiguously 2 times.
In general, I want to give her cunnilingus, etc., but how can I go out with her on this? I don’t understand the topic at all.
What do you say???? Thank you in advance.
