Ok, so this happened tonight, just a few hours ago. It's a small and not all that crazy story that I nevertheless want to share but couldn't find any existing thread it exactly fit into...
Tonight me and my wife went through the Taco Bell drive through to grab some dinner. I was driving; she was wearing nothing but a tank top above the waist, no bra. After we ordered and were in the lineup for the food pickup window behind a couple other cars, we were kind of chatting. Then she went "Hey, look."
I looked over at her and she glimpsed down, so I did too - she had moved her breasts up, or pulled the top of the tank top down (or probably a mix of both) so that about half of her nipples were peeking out from over the top. It was just enough to be clearly visible (or at least it would have been in the light, the dark made it more hidden) while still being subtle enough that it passed as an accident.
I was obviously happy but surprised - we hadn't even been talking about anything sexual! I laughed and told her I approved somehow or another; I don't remember exactly what I said. But after we were just one car away I asked if she was going to fix it before we pulled up to the window and she just smiled and went "No."
My heart pounding a bit, we pulled up and the guy at the window told us our amount and I handed him my card and he handed us our food. My wife's nipples were out the whole time but the guy didn't react - if I had to guess I'd say he didn't see, as it was fairly dark and it's possible that that mixed with him not looking that hard past me at the passenger side of the car means he easily could have overlooked it.
But still... he COULD have seen, and just played it cool assuming it was an accident. This is the Taco Bell we always go to and we see this guy all the time; it's hot that we'll never know if he's seen my wife's nipples or not. It's also hot that my wife did this completely on her own initiative, no hints or prompting from me whatsoever.
