One thing about Khloe Kardashian … she does not fear the X-rated — and yep, she went straight for it, handing out festive-season relationship tips that somehow turned into blowie talk!

During a festive “Kimsmas Live” on Kim’s TikTok Wednesday, Khloe hyped a fan up to get lit at the holiday party, hook up with her crush and “give him a blowie in the closet” … sending momager Kris Jenner into full-blown horror.

Kris — flanked by Kyle Richards and Kathy Hilton — nearly passed out, reminding Khloe this was a family show. Khloe quickly corrected her, saying it’s TikTok … then carried right on chatting about blowjobs like it was no biggie.

She wrapped it all up with some, uh, heartfelt wisdom … telling the fan if she wanted to give the guy she fancied a blowjob in the closet during the Xmas party, he’d most definitely say yes. Okay, noted!
