I'm at the hookah bar, I'm at the adult shop, I'm at the combination hookah bar/adult shop
Kurosawa new best girl. A functional adult who owns a business, that shares his hobby? Forget smashing his half-aged coworker, this is a real woman. All of the fun without any of the risk!
I have zero confidence that those are bona fide Miyama Yuri pantsu. It's much easier to shrink-wrap fakes for mass production. If they were legitimate intimates, you wouldn't sell them in a random porn shop but in some kind of auction for rare goods, or at an AV convention. When selling collectibles, you need to create the aura that distinguishes them from average goods. These are packaged like a pack of chocolates.
