Now that she has hit 50 she is more self-conscious and flashes less, but not long ago she was all for showing off. A few times she did...
Shortly after moving to North Carolina we took a late evening trip (around 9:30) to Walmart for some supplies. It was summertime and hot so she was already only wearing a loose-fitting, sheer white, button-up top with no bra, bikini bottom and flip flops. Her tits were fairly visible through the top, but it was loose fitting enough that it was mostly hiding that she was braless. As we walked thru the store I noticed several guys checking her out and mentioned it and added that she should unbutton her top a few more buttons and give them a show. She smiled and agreed and did, leaving just the bottom three buttons hooked and dropping the opening down for a good cleavage show. After a few minutes she said "One more" and undid another button. I said "My turn" and undid another one leaving just the bottom button hooked. She said "OK, but if it comes open it stays open!" and left it. Now when she walked the air from her walking caused it to swing open and fully expose her tits. Several guys were going out of their way to be near her and get a show and she was loving it.
When we went to check out I was putting stuff on the counter while she stood and waited. I noticed two Mexican guys looking at her from a few registers over and talking. I looked at her and saw that the top was fully open. Luckily this was before cell phone cameras and security cameras were not very good. Those two guys followed us to the parking lot where she took off the top, got on her knees and gave them blowjobs.

It was 2002 and we went to the WV State Fair. We knew it was going to be hot and I encouraged her to wear something sheer and showy that would also be cool and she agreed, putting on a see-thru bra and see-thru top. She was still breastfeeding and her nipples were extra dark and really showed through. Needless to say, the locals were thankful. We had just moved back home less than a year earlier and while she was fucking occasionally, she was looking to get active like she had been in NC again. The fair trip helped. The highlight was when we went into a building to cool off. I had her pose next to the men's restroom door and snapped a pic. Camera quality was terrible back then, but you get the vibe.
