Sofia Richie Sexy Dances To Dad Lionel's Music While Scott Records

Sofia Richie got down and dirty -- sexy dancing for boyfriend Scott Disick -- and it was all while her dad's music blasted in the background.

Disick shared the clip of a 19-year-old Richie in some skimpy Santa gear moving her hips and shaking her ass in his kitchen. It's a whole lotta awkward, considering the song she's gyrating to is Lionel's "All Night Long."

34-year-old Scott has been seemingly settled down since getting with Richie months ago ... looks like their recipe for fun is some one-on-one dance parties.
