England number eight Simmonds went over following a first-minute score from Zach Kibirige, a late replacement for Alex Tait at Kingston Park on Friday.
Simmonds touched down again when the Falcons were unable to stop a powerful driving maul following a line-out from close range, the back-rower’s brother Joe converting for a second time.
Toby Flood’s penalty three minutes before the break reduced the deficit to 14-10 and the Falcons were level at 17-17 when he converted a try from Johnny Williams, which was reward for a sustained period of pressure from the home side.
A yellow card for Flood 17 minutes from time proved to be costly, though, Matt Kvesic applying the finish in the left corner following a subsequent catch-and-drive to give last year’s runners-up a fourth win out of four.
