Narrative:

Cleared to land runway 36R. Runway 27 was also in use. I touched down about 500' past threshold 36R. There were no instructions from tower after T/D. I started right turn off to runway 27 to proceed to hangar 1 FBO. I immediately noticed twin engine aircraft on 1-1 1/2 mi final to runway 27 with lights on. (My landing light also on even though bright daylight.) I immediately stopped turn to 27 and turned back to 36R taxiing north past 27, before tower instructed me to continue taxi on 36R. I believe pilot of twin requested go around which was approved by tower, who, I believe, cleared him to land 36R. I exited 36R by next taxiway north of 27. I was handed off to ground from tower. All communications thereafter were normal. Copy of airport diagram attached. I had 1 passenger on board.
