Kanye West -- Grabbing a Handful of Kim Kardashian's Ass!!

Kanye West is protecting his gluteus to the maximus.

Kim and Kanye are in Paris for Fashion Week and Mrs. West posted a picture on Instagram of Yeezus showing his affection for her backside.

As we previously reported ... Kim upped her security detail this week after she was almost tackled to the ground by a crazy person during an event in Paris.

Good thing Kanye's got her ass covered.
