In the Elfwood, you are captured by a big breasted elf with sultry bedroom eyes and exquisite soft skin.
Don't let her looks deceive. You are her personal sex slave.
The elves have a healthy libido and this one plays rough.
She declares that she's going to use you until your dick breaks.

So long as you can keep her happy, you're okay.
But how long much sex play can a human male take...?
