We know Kim Kardashian is a big fan of inappropriate mirror selfies, but this is too much ... The 33-year-old reality star squeezed her (in)famously curvy figure into her little sister Kylie Jenner's black bikini, and proudly posted two snaps to Instagram.

"Yep stole Kylie's bikini...she's not getting it back," busty Kim captioned one of the pics.

Just to put this in perspective -- Kylie is 16, and built like a twig. Kim, not so much. Well, see for yourself ...
