I got this from another forum. What you do is write about 3 words, and then the next person continues on from there. You don't have to write only about Damon & Elena, you can add whoever from the Vampire Diaries as you want, but since it is the Delena spot, obviously there are going to be lots of them in this story. It can continue on as long as it wants.

for eg.

person 1: Damon was walking
person 2: to Elena's porch
person 3: to get her

etc.etc.

It continues on, I hope you all understand. (:
Have fun!
