The Jenner sisters clearly have no problem showing a little skin.
Kylie Jenner is showing off her sister Kendall's edgy side.
The 19-year-old reality star took to Instagram on Friday to share a snap of herself and Kendall getting their party on -- featuring a cameo by the model's nipple ring.
The sisters keep close in the black-and-white pic, while Kendall's nipple ring peeks out from behind her lacy bralette. The 21-year-old model also shows off her toned abs in a body chain and printed bomber, while Kylie appears more covered up in a white jacket.
"Through @490tx eyes," Kylie captioned the pic, shot by pal Moises Arias.

Kendall certainly hasn't been shy about showing off her nipple ring, often flaunting her piercing in sheer outfits around town.
"Having my nipple pierced isn't really something I make a big deal of, but I think people are obsessed with the topic because it seems so unexpected of me," Kendall explained on her app last year. "Before I even decided to go for it, I just liked showing my nipples through some of my outfits; there's something understated, yet sexy about it."
But Kendall's sexy jewelry is nothing compared to the steamy short film Kylie released earlier this week.
