The Begging, The Middle, The End, The Afterparty

Once upon a time,

In a land far far away,

She comitted a crime,

To lock her up more than a day.

Her prison a castle,

Where sleep an addiction

And dreaming a hastle,

That became an affliction.

Don't quote me on this,

But a lie I can't tell, 

She gave me a kiss, 

To put me under a spell.

It changed me somehow, 

To this day I feel diffrent,

I look like a sow, 

And now I'm astringent. 

Her guard was I, 

And I her muse,

From her freedom you'll die,

And I you'll accuse.

Don't blame the witch,

She meant no harm,

But let her hitch,

And she'll cut off your arm. 

Make it into a stew,

And add some spice, 

Then she'll feed it to you,

Now isn't that nice?

This isn't the end,

This isnt the middle,

This is the afterparty,

Can you figure the riddle?
