Should I tell my BFF that I want to give a speech at her wedding after she told me they hadn't planned on it?

I’ll be brief. My BFF and I have been friends for nearly 25 years. She is getting married soon. Her sister (married) is the Matron of Honor and I (single) am the Maid of Honor.

Today I found out that my BFF and her fiance had only planned on her sister and his best man giving speeches. I was really looking forward to giving a speech of some sort, even if it’s just a quick toast.

How can I tell her I would like to give a speech without coming off like I’m demanding one and as if I’m purposely going against her wishes?
