This a recent, true experience.
My husband loves for me to show off for people in public places. It turns him on more than anything else. It first started mainly as flashing truckers as we passed them on the interstate. Now, it seems truckers never really pay attention. When we do get someone's attention, then we would pull off at truck stops or gas stations with a large parking lot for truckers, to park by them and let me pull my large DD breasts out or spread my legs for them to see my pussy. When we first started this, my pussy had a trimmed, strawberry blond bush, but for the past five years, I have kept it cleanly shaven.
Given the lack of success with truckers, we began looking for new experiences. One place that we have had some recent luck is hardware stores (like Home Depot, Lowes, or even small-town Ace Hardware stores). It takes the right mixture of a little alcohol in me, a good top that allows for easy breast displaying, and the right mix of customers (not too crowded, and more single men than families, etc.) It is still somewhat hit and miss as to whether it will work, but when everything falls in place, it is a very hot experience for all involved.
Several months ago, we were in a large hardware store. I was wearing a black plunging shirt with a short skirt. We were on the plumbing aisle and as we acted like we were looking for something for our house, I would slowly pull my breasts out to flash my husband. An employee apparently noticed what we were doing and began watching us. I was getting turned on with my exposure, but also very nervous about what I was doing. I covered up and we moved to a different aisle. As we walked away, I reached over and touched my husband's crotch to feel his hard-on.
We walked around the store some more and noticed the employee was staying nearby. When went to the bathroom and when I came out the employee was standing at the end of the aisle to see where we would go. Realizing he seemed interested I would make eye contact at times. Once my husband is aware that someone is watching, he begins to get very turned on.
We eventually made our way to the shower aisle where they have big inset displays out of the range of the end of aisle cameras. The employee followed us and stood about 10 feet down the aisle to watch. I again pulled out my breast from the plunging shirt until my full breast was exposed and my nipples were hard. I picked up an item and he moved closer. He asked "what do you want?" I noticed I was breathing harder and looked at my husband who clearly was also lost in the moment. I responded "do you want to touch my breasts?" I then leaned in standing there for a bit with my breasts out of my shirt allowing this employee to stare at me and then reach out to touch my breasts.
The employee stepped back into one of the insets in the shelves and motioned us to come over. He then pulled my right breast out of my shirt again and pinched the nipple. Not satisfied he then pulled out the left breast and begin pinching. He asked "do you like this? Is your husband ok with this?"
I answered that "he likes to watch men touch me." He took my left hand and placed it on his hard crotch. He felt very hard and very large and long. As we would move my breasts would get covered up again by my shirt, but our friend would have none of this and he would pull my shirt apart to expose both of my large tits to his hungry eyes. "Do you want to do more?" he asked. "Come back on my lunch break. I can meet you outside."
