This might be fun ... take an ol' nursery rhyme and alter it a bit to give it a "Pixie" flavor. Can be short or long ... for example:

Jack and Jill went up the hill
To fetch a pail of water.
When Jack came down
He had a frown,
Cuz' Jill left with Mad Hatter.

Here comes Peter Cottontail,
Humping pretty Paulie's tail,
Pumping very quickly and quite fast.

Now he's getting all flushed red,
I think he's 'bout to soak the bed,
Just ain't no way that bunny's gonna' last.

Little Paulie's on the edge,
Moaning there right on the bed,
I think she's drained our Peter's poor ol' mast.

Now the story's almost done,
They're cleaning up the gooey cum,
I suspect, tho', this time will not be their last.
