Could somebody explain to me what this short french film is about?

I watched “Vésuves,” a short animation by a GOBELINS student, but it’s some sort of mind rape…

The description reads “Two men look at a woman. One wants her, the other one gets her,” so watch it and try to make sense of it…

All I can say is THOSE EYES AT 0:54! O_O! And dat ass at 1:07 xD, but seriuosly I don’t get it!

I know there’s a ton of symbolism involved, but I don’t understand what the guy who enters the room is doing, specially what he does with the phone o_O

I love the style, but the story is just creepeeh!
