Marie and Koharu checking each other's armpits is incredibly erotic! Koharu sweats a lot, and due to nervousness, her armpits are dripping with beaded sweat. Marie, who loves bodily fluids, starts licking it up, shyly yet curiously commenting on the taste and smell. Marie adores tickling armpits, and as she tickles Koharu, she keeps licking her. The chemistry between the two, combined with their intense armpit fetish, creates a delightfully naughty scene!
