The rule: make a sentence from the letters of the last word of the previous sentence.
Some additional rules:
Always keep the order of the last word's letters.
You can make two (or even more) sentences out of the last word's letters, if necessary or otherwise suitable. (This doesn't mean making alternative sentences of all the letters, but making a sentence from the first few letters and another sentence from the rest of the letters.)
You don't need to be very strict with the words you use: you can sometimes put in something not quite English, but try to make it understandable enough for others to guess the meaning, though.
You may also twist the grammar if needed.
