As long as the bed is disc shaped and you both really like each other - just relax and let the nature take it's course.
On the more serious note - discs won't bed from time, but from braking. Find a safe piece of pavement and get it over with. Best thing IMO is to start slow - dragging the brakes gently, at low speed to heat them up (but not overheat them). About 3-5 seconds of dragging, then cooling off for about 10-15 seconds. Make several rounds.
Then make a few moderately strong stops from about 50 km/h speed.
After that, make a few hard stops (again, safer at moderate speeds, at least for the first two).
No need to make a full (complete stop), perhaps even better not to.
Ride a bit to let them cool of and you're good. Proceed as usual. That should do it.
