The One Who Screws Up Prophecies is given the Gift of Knowledge... without needing to pay an eye for it. Rating is for later parts, in which Xander gains a harem.
A very short parody (well, sort of) of the 'marriage/concubine/whatever contract' trope.
Willow wants to give Xander what he deserves. Rating is for later chapters, which will contain explicit sex, among other things. Updates may be very slow.
