If there a way I can get the start line in operatorfunc?

I'm working on a comment plugin, I want to check the line that curse on just before motion start, the code is like this:

nnoremap <silent> <leader>c :set operatorfunc=<SID>CommentLines<cr>g@

function! s:CommentLines(type, ...)
echo getline('.')
endfunction

Imagine the working buffer like this:

aaa
bbb _
ccc

When user type `<leader>cip` in the second line, the `getline('.')` would always return the first line `aaa`, but how can I get the line where the user start this motion ? which should be `bbb` in this case.

Thanks for any kind of help!
