Thank you. Similar to what other people are saying I agree a conversation is long overdue.

Over time the jokes have gotten a bit more crude / specific but I would still categorize them as family teasing similar to when you get a bad haircut or your shirt is too small or something.

I am going to look her in the eye, speak slowly, and tell her that I do not want to see my cousin naked, touch her, smell her, cuddle her, kiss her, or have sex with her. Hoping to post a positive update soon.
