From squats to ass licking

I am instructing Christina in some squats, and realize she does it wrong.
So I instruct her how to do it properly. When my hands touch her hips and
ass, I suddenly get so horny! SO the instruction ends, and I pull her
training shorts and underwear off. I start putting my tongue in her ass
hole, and she really love my licking! When I am done we turn the table and
Christina give me a very horny payback!
