Kylie Jenner flashes, well, everything in NSFW photo in celebration of her 20th birthday

Kylie Jenner is officially 20 years old -- and what better way to celebrate than with a nearly-nude photo?

The reality star thanked fans for their birthday wishes with a series of ultra-risque photos in which her nipples are fully visible through a sheer bra. Although nothing really surprises us anymore, the images are -- dare we say -- even more overtly sexual than other past posts.

If you aren't able to take a peek (since they're definitely NSFW), the photos show Kylie in a bubblegum-pink wig, posing seductively in barely-there lingerie.

Kylie rang in her 20th with her closest family and friends, who gathered for a surprise party in LA on Tuesday. In attendance were Kylie's boyfriend, Travis Scott, as well as most of her immediate family, but not all: Caitlyn Jenner was absent, as was Kourtney Kardashian, who's currently vacationing in Egypt.

"Happy birthday my baby @kyliejenner!! You are my sister, best friend, business and life partner!" wrote sister Khloe on Instagram. "You inspire us all!"

The Kardashians are no strangers to massive birthday celebrations, outdoing themselves year after year. In June, Khloe turned 33 with a birthday blowout for the ages -- and all of her sisters were on hand to surprise her at the bash.
