Narrative:

After landing on runway 13R at dfw we were told to hold short of runway 18L at taxiway a. There were 2 heavy aircraft holding short of runway 18R at taxiway a already so tower told us to hold short of runway 18L at taxiway B. I read back the hold short clearance and the captain acknowledged. I then continued to clean up the aircraft finish the 'after landing checklist' and was about to call our ramp when the captain slammed down on the brakes. I looked up from the checklist to discover we were in the middle of runway 18R. We continued across runway 18R to hold short of runway 18L. The aircraft landing on runway 18R was at about a 2 mi final. The captain explained he saw the aircraft at 2 mi but was watching the aircraft holding short of the other runway (18L) at taxiway a and was proceeding up to hold short next to them on taxiway B when he realized where he was and remembered he was to hold short of the other runway 18R. The captain was busy looking at the other aircraft and where they were holding short more than where we were on the airfield and I should have backed him up better but was busy with checklists and calling ramp.
