Venusss Fetish - I shave her armpits and then lick it

I invited my step-sister to my house, and I soon noticed that her armpits were still hairy.So I convinced her to shave her fur, and the sight of that smooth, white armpit immediately sparked my desire to lick and sniff!She's so sexy I can't resist! My step-sister joins in, and I start licking her armpits intensely.My tongue goes up and down while my nose smells!It's an explosion of senses!She gets tickled sometimes, but I don't stop until my tongue gets tired of this pleasurable exercise!
