It’s your genitals!
Do they need a little bit of pinking up? My New Pink Button has something for you! It’s rouge that you can apply to your ladybits. And they all have names like “Bettie” and “Ginger” so presumably your down-there-parts will look just like your favorite pin-up girl’s. Of course, this seems like it could be a bit worrisome when your partner rubs it off and wonders why you are applying make-up down there, but maybe they’ll… appreciate it? Yes, that’s right. Appreciate it. That’s exactly how they’ll respond to your painted lady-parts.
