I don’t get out much, but when I do it’s likely to get food or buy an inanimate sex object. What I’ve noticed in my 45 years of life that almost exclusively, when you buy something naughty, it comes in a black bag. It is like a red flag siren going off that you picked up something to stick in a hole, or jack off to in a movie or while an object is stuck up your butt. It’s like a signal, a tell-tell sign that HEY, you purchased something naughty.
It’d be great if they’d just put it in a clear bag, like you place produce in at the grocery store –then walk home or to your car with it.
