Custom cursor with trail effect - Adding a trail effect to my cursor.

I'd love to add a trail to my current custom cursor. I've put a website with some examples, but instead of adding a different trail I'd like to just make a trail of the same design. Example: My custom cursor is an arrow, a trail of arrows shows when moving the cursor. 

Any thoughts? Thanks a lot !!! 😄
