Need a little help.

I'm writing a book with an erotic theme.

Now I haven't finished a novel, but I have lots of experience writing.

One writing coach says that every good story should have four parts. Three great disasters and an ending that ties everything together.

I have my three major disasters and my ending, my problem is filling in minor scenes of every day activity. Like sitting on the porch or flying a kite.

If you have any idea's for scenarios where my two main character's (a man and a woman is pretending to be human) to grow their love.

Thanks!
