It was all one-way traffic in the opening half with Leinster leading 27-0 helped by tries from Contepomi, Robert Kearney and Keith Gleeson.
Gordon D'Arcy, Cameron Jowitt and Kearney again crossed the try-line as Leinster took complete control.
Bourgoin scored a consolation try through centre Glenn Davis.
Leinster had their first try in the seventh minute when the 22-year-old Kearney fended off a series of weak tackles to cross the whitewash.
Contepomi converted and added a penalty on the quarter-hour for a 10-0 buffer before good support work and off-loading allowed Contepomi and then Gleeson to cross.
Cruising at 27-0, D'Arcy notched Leinster's bonus point try four minutes after the restart when he was helped over by the impressive Dempsey.
Davis replied for Bourgoin, ducking out of hooker Brian Blaney's tackle to go under the Leinster posts.
But Leinster eased out to the half-century in the closing quarter as number eight Heaslip sauntered over while speedster Kearney blazed over for another try from his own 22.
Australian import Jowitt completed the try-glut after 78 minutes from a Contepomi kick to the corner.
