Kylie Jenner Covers Herself with Just A Sheet in Sexy Instagram Post

Kylie Jenner's a rose without any thorns ... posing with a flower, a bed sheet and basically nothing else in some new photos she shared to social media.

The reality star and beauty mogul posted a good old fashioned photo dump to Instagram Saturday ... which included a couple photos where she appears to be posing in front of a window au naturel.

We can't say for certain ... but, given the skinKylie's showing in the pics, we think it's fair to assume she's dressed only in her birthday suit underneath the bunched up comforter.

She smooched the flower she was holding in another pic ... with her white hair clip standing out against her jet black hair.

Jenner kept up the scantily-clad theme across the other photos she shared, too ... like this one where she showed off her lacy bra in a mirror selfie.
