That last one obviously means humping, so it's fitting that 170N, or "Sequence of Love" -- they all have weird, love-related names -- is the perfect glossy cherry Popsicle red of my porno dreams.
I think all heterosexual women should have a great blowjob in their arsenal alongside like, ability to change a tire. It's just so powerful. If you're really great at giving a blowjob, you don't even have to be that nice to your boyfriend/husband. (The first time I typo-ed "husbad" -- Freudian?) It's like one of those mind eraser things from "Men in Black." You can tell a man you just banged his best friend, but then if you blow his mind with your mouth sex, afterward he'll be all like, "What? I didn't see any aliens."
In case you are turned off by my shoddy application (it was nerves!), here is Emma Watson wearing the shade in the advertisement. Not that I'm suggesting anything about her blowjobbing abilities. Wizards probably have some kind of beej spell so they don't have to get their jaws sore or worry about somebody cumming in their eyes. (Emma Watson, I am sorry to have put this sentence anywhere in the vicinity of your pretty face.)
