Author's Note 1st (please read)

This is a one shot lemon! This is also a "Yu Yu Hakusho" fanfiction. If you haven't seen this anime, it is AWESOME! If you don't know what a lemon is just google something like "YusukexKeiko lemon fanfic". Yusuke has just come back from the demon world and has reunited with Keiko and his friends.
Anywho, it should be pretty heated ;)
