Exhibitionist wife explores Boundaries

My wife is interested in exhibitionism, and she was very open about this during our dating period. She genuinely found a thrill in showing herself, but it was never a deliberate or arranged scenario. It was always more of an accidental occurrence, often stemming from her wearing clothing that could potentially be revealing.
She really favored styles like Mimi skirts and short shorts, along with wrap half tops. Her general preference leaned towards looser-fitting clothing. We spent some time discussing what might potentially happen in a suitable environment.
And it could give a male-friend the idea of something evolving into a situation that becomes more personal, maybe something like a one-on-one encounter or perhaps even involving a group of people, depending on who was around and how many were present.
We came to an agreement that she wouldn’t tease any of our male friends unless she and I had a really serious discussion about it first.
That conversation actually happened a lot sooner than I had expected. We were just lying comfortably on the couch, watching something rather explicit.
And then, there's a scene involving a man and his wife who spontaneously decide to invite a male friend to join them.Cassie told me that, saying, "You know, if it were to happen like that, I wouldn't mind giving it a try, though, with the right guy."
I told her that Joe really is a true friend to both of us, both when we're individually together and when we're together as a pair.
She responded by stating that it implies that there exist feelings, almost like a fundamental element of a certain type of love, shared amongst all of us. I added, "Yes, and perhaps making it a more gentle and meaningful experience specifically for you." With a tear welling up in her eye and a genuine smile on her face, she whispered, "I love you," before kissing me.
We had plans for Joe to come over and assist us with painting the ceiling of the bathroom. We were also planning on having a cookout. Later in the evening, we were looking forward to enjoying our new swimming pool while having some cold beers.
When Joe arrived, it had already started to get hot. So, I suggested that we have some fun before heading into work, and I added to that, "Let's go for a little swim in the pool." After that, I turned to Cassie and said, "Would you be able to go get a bikini for yourself, and would you also mind bringing along a pair of my shorts for Joe to wear?" She replied that she didn't actually own a swimsuit. So, I asked her, "What about a pair of your shorts and one of your tops?"With a grin on her face, and I think perhaps realizing where this situation might be heading, she responded with a simple, "Yeah, I could do that."Cassie returned and made a statement to anyone who was listening, but it was more specifically intended for me. She made a comment to the effect of, "I don't have any panties that would be comfortable when they get wet." I responded by saying, "Then don't wear any," and added, "Besides, those should be taken off after they get wet." With a playful laugh, as she left to remove her panties, she asked, "Are boxers okay for you guys?" as she tossed them to me and added, "Hurry up, I'll be back as quick as I can." Just as we were in the process of pulling the shorts up, she arrived. We heard her say, "With all the moons I just saw, I thought the day was over." She then added, "I've never seen such a cute moon before, and I'm so lucky to see two in one day."
I intentionally allowed Joe to pursue her up the ladder. As she finally realized that it was Joe who was right behind her, she started moaning slowly, and she actually looked like she was about to slip.So, I think she was consciously making sure that his eyes were definitely where she wanted them, as he carefully traced his hands up to steady her legs. Nothing was said we all just got into the pool for some relaxing fun. We had been swimming for approximately an hour before I finally spoke up. I then suggested, "If you want the ribs smoked, I'm happy to get them started and then just keep going while you two just bang out the ceiling. You can just let me take care of the ribs, and I'll even play fetch boy for you both."
Cassie then asked Joe if that was something that would work for him, and he responded with a simple nod, saying, "Sure, it works for me."
Cassie will be taking over since I was not present

So, Joe and I went over to finally tackle that ceiling we've been putting off. He went to go grab the ladder for us, while I was meanwhile getting all the paint ready to go. Joe then came in, set the ladder up right over in the far corner.
After that, I climbed up the ladder and politely asked him if he would be willing to hold it for me. Following that, I also asked if he would be able to put the paint onto the tray holderI was attempting to subtly observe whether he was directing his gaze towards my pussy. However, I quickly recognized that he was actively trying to look without getting noticed. Consequently, rather than attempting to catch him looking, I now simply looked upwards, hoping that he was pleased with what he was seeing.And I made sure I was positioned just right so that he could get a good look at it. After that, Joe then asked me directly, "Did you stir it really, really well?" To that, I replied, "Probably not, you might want to make sure it's smooth enough for dipping into."He said, "It definitely looks nice and smooth to me."
I suggested saying, "Well, why don't you put your stick in it to make absolutely sure that it's completely ready for easy spreading."My husband, Richard, came in to check on us and ask if there was anything we needed. He asked, "Is everything okay in here?I quickly let him know, saying that I think we're doing really well and that we seem to have a good handle on everything. I was sending a little hidden message to my husband, but he actually responded to it saying, "Well, if it does get harder, can you handle it? That's because I'm currently in the critical part of our dinner right now, and I won't be able to leave it."
And added, "Let me know how it comes out." We moved the ladder in front of the door.
As soon as I began climbing up the ladder, I noticed Joe was right there behind me, holding onto the rungs. Once I had my waist about at the height of his forehead, I started to ask him if he would consider swapping places with me. As I turned around, which brought his face right up to the level of my pussy now, I paused for a moment and added, "Unless you're actually enjoying the view you have and like what you see." I was genuinely surprised when Joe replied to me, saying that he definitely liked what he saw and that it looked really tasty. I called his bluff by reaching down to pull the crotch of my shorts to the side, telling him, "If you want to find out, be my guest." I could feel his breath on my pussy lips as he spoke, saying, "Don't mind if I do."
The next sensation that washed over me was the feeling of his tongue parting his lips, and simultaneously, a tingling sensation began to spread through my entire body. Soon I was begging him, not to stop as I came. I told him, "My turn."
