I saw my first ever black cock t-shirt in public yesterday, at a market. The woman was probably early 40's - cute, but nothing special. The shirt had "BBC" across the top, an image, then "Lover" along the bottom. It was very old, and scruffy looking - so I had to sidle round to get a look and try to make out what the picture was. It was a younger version her in a bikini top and denim shorts, sitting on a bench. So, she'd got it personally printed with her image.
Unremarkable, but sweet!
I'd seen jewelry before, and some tats, but never a shirt.
