Millie’s face is very expressive and revealing of her unique personality...another nice job along those lines. I love the “knowing” look she shares with the viewer, letting us in on who is really running the show. I wouldn’t call it “topping from the bottom” in the pejorative sense, though...Millie is far too sly for that sort of obvious behavior, instead keeping it a private little secret between herself and the viewer, as her expression abundantly reveals. Also, do I detect feminine fingers pulling at Millie’s panties...? I bet that “student” is in the loop.
