France ran nine unanswered tries past Scotland to leave Bryan Easson's side without a point after three rounds of the Women's Six Nations.
After a relatively close opening 40 minutes the hosts ran away with the game, crossing the white line six times as they barely let Scotland put hands on the ball.
Fullback Emilie Boulard bagged a hat-trick, while Pauline Bourdon, Melissande Llorens, Gaelle Hermet, Gabrielle Vernier, Romane Menager and Maelle Filopon also scored.
The bonus-point victory puts France a point behind England in the Six Nations table, while Scotland sit bottom.
The visitors are now without a win in 12 competitive fixtures.
Despite the scoreline, Scotland dominated possession and territory in the first-half which still ended 17-0 to France who showed a clinical edge whenever they entered the opposition 22.
It looked like the hosts in Vannes had scored straight away when Charlotte Escudero crossed, but the offload which she received had gone forward.
They didn't wait all that long to break the deadlock though, with scrum-half Bourdon benefitting from Llorens break up the blindside wing.
Llorens was the next to dot down, as Boulard hacked the ball over the line after France stole a line-out on Scotland's five-metre line.
Three minutes before the break, France got an inevitable third. From a throw on Scotland's 22m, the hosts rumbled through the phases before spreading all the way to the other touchline where Boulard slid in at the corner.
Gaelle Mignot's side moved through the gears as soon as the second half began. It came from individual brilliance from Verner - a delicious little offload out the back - before Boulard went into the corner for her second and France's bonus point try.
Llorens almost had her second, breaking free before being caught by Chloe Rollie, but the winger was able to pop to Hermet who dropped over the line.
Scotland were wilting in the heat of north-west France, and Bourdon soon put Vernier through a gap with the centre powering over from close range to add her name to the scorers.
Within two minutes, France had their seventh. Bursting through the middle again, they recycled it wide and Caroline Boujard popped inside to Boulard who cantered in for her hat-trick.
The eighth try was a bit special. The build-up was similar, but ended with Marine Menager passing to twin sister Romane to score.
There was still time for one more. Winning a scrum against the head, the hosts camped themselves on Scotland's five-metre line and eventually went wide, with Filopon touching down.
Nine tries and five conversions - France were simply breath-taking in the second-half. The disappointing thing for Scotland was failing to capitalise on their first-half chances, crossing the line from a driving maul and being held up was as close as they would come.
