The 17-year-old reaches around her model sister Kendall Jenner's super slim waist before sticking her hand down into her pants, which seemingly catches Kendall off guard. "Kylie, ohhh!" she exclaims before the video ends.
In another video added to her story, Kylie shows off her new earrings and says she has "New jewelry in other secret areas" with her nipples circled in red. We're not sure if she's joking or actually got her nipples pierced, but nothing would really shock us at this point.
Do you think Kylie's being inappropriate?
