Umm we aren't sure if Kylie and Kendall Jenner got the memo that sister-on-sister fingering isn't so hot. Yesterday, 17-year-old Kylie posted a very sexual Snapchat of her sticking her hands down her sister Kendall's pants. Yes -- you read that correctly -- sister-on-sister fingering.

They think they're goofing around -- but really they are just making everyone uncomfortable. Ahh sisters aren't supposed to do that! In the short video, the youngest Kardashian sister reaches around her big sister's waist and then heads down -- like all the way down. Kylie is disgusting -- we already knew that -- but we thought Kendall was better than that. Guess not!
