Kim Kardashian may be no stranger to the frequent cleavage-baring selfie, but her latest two pics are just OTT!

The pregnant star must be a big fan of her expending bosom as she showed it off to its fullest in what appears to be a PVC dress alongside sister Kourtney Kardashian on Saturday.

The sisters appear to both be wearing the same Bettie Page-style wigs and the same color of garish purple lipstick in the photo, which Kim labelled "Banger sisters."

Kourtney seems to have jewels hanging off her bondage-style outfit, while Kim's garb seems to be barely containing her assets.

The next image, apparently posted to celebrate the 34-year-old reality star reaching 42 million followers on Instagram, is nearly entirely bare-breasted.

Not gonna lie though, they are looking UH-mazing.
