nobody knew why lucy locked her self up in her bedroom only natsu would know for he is the cause you see natsu an lucy want to keep their relationship under the radar because natsu couldn't go a day without being inside of lucy which much to lucys dismay would happen so natsu has been " getting it on " with lucy everyday and lucy would still be asleep when he left for the guild so he would come home to lucy in the kitchen cooking diner while naked for she was to lazy to get dressed which natsu loved but tonight was different.
