My Birthday surprise

I have fantasized about seeing my wife sexually interacting with another man for some time now, and I have expressed my interest to her many times. Of course, she has always made it clear that although it seems like it would be fun, she didn't feel that it would be right.
I suppose I don't see it from the same perspective as her though. I guess I view it as an opportunity to experience new sexual pleasure without personal attachment.
One thing about her though, when stepping outside her "norm", it's usually spontaneous and depends on what kind of mood she's in.
Well...... it finally happened! It was my birthday, we were out for dinner and a few drinks, and the place was really busy too!
We had finished dinner and were sitting at a table listening to the band play. Seating was limited, and we just happened to have two empty seats at our table, and two younger men that just came in asked if we'd mind if they could sit with us.
Over the next hour or so as we were enjoying the music, I noticed Brenda had been spending quite a bit of time engaging one of the young men in conversation. She almost seemed a bit "school girlish" as she would over exaggerate her laughter at some of the things he would say. And her behavior reminded of how she would act toward me way back when we first met. It was actually kind of cute.
After a few more drinks and a few more songs, the young man asked me if I'd mind if he'd ask her for a dance, and I said it would be up to her.
As Brenda grinned, and looking at me, she stood up, gave me a kiss, and headed out on the dance floor with him.
I have to say that as I observed them on the dance floor, it was refreshing to see her behaving like the giddy high-school girl that I once met well over thirty-five years ago.
As he held her in his arms, dancing to a couple of slow songs, the two of them continued talking and laughing.
When they returned to the table, Brenda whispered in my ear, asking me if she could invite him to our home for a few more drinks, and I agreed. Then she kissed me, and told me that she had a huge birthday surprise for me when we got home.
As we sat there listening to a few more songs, Brenda couldn't keep her hands off me, and kept rubbing her hand along my inner thigh, while fondling my cock from time to time under the table.
After a period of time, Brenda leaned over and whispered in the young man's ear, asking him if he'd like to come by the house for a while? And with a smile, he accepted her invitation.
When we had gotten to the house, I made us all some drinks and Brenda got out a meat and cheese tray with some crackers, and we all went out to the back patio to enjoy the cool night air while sitting around a fire.
For some reason Brenda seemed to be getting a bit nervous after a period of time, and I soon found out why. After a while she had asked me to go into the house for a minute so she could ask me a question. Once in the house, Brenda wrapped one of her arms around my neck, pulling me in for a kiss, while putting her other hand on my crotch, rubbing it, then whispered in my ear asking me if I was ready for my surprise?
So I asked her what it was? And she said "you'll see!", while nervously grinning at me.
Then she asked me to stay in the house while she went out to invite our guest back in.
When she came back in, leading him by the hand, she brought him to the couch and asked him to sit next to me, and asked me if I was sure I wanted to go through with this, and I said I would love to. After that, she knelt in front of him, and as she nervously looked at me, she began opening his pants. Once they were opened she had him raise up a bit so she could lower his pants. When she removed them, the look of surprise on her face was priceless as she revealed his rather large cock.
Then she cupped his balls in her left hand as she wrapped the fingers of her right around the base of his cock. As she lowered her face to the tip of his cock, she slowly began licking it while looking at me as I watched intently. Despite the fact that she had one of her hands wrapped around it, there were still at least four inches sticking out of the top of her clenched fingers.
Needless to say, by this time, my cock was hard enough to pound nails.
After she had spent a few seconds licking it, she slowly slid her lips over the head and began sucking it as she inched her way downward (watching me the whole time). As her nervousness began to disappear, she became more deliberate and she started bobbing up and down taking a little more in each time, then she started removing her fingers one at a time, so she could suck more into her mouth.
As her tempo picked up, and I could tell that she was really beginning to enjoy herself, moaning loudly while savoring it (she has always expressed how much she enjoys sucking cock, and she is exceptional at it!).
I could also sense that a wet spot from pre cum had made its way to the inside of my pants from watching her suck him. Although I had fantasized about this numerous times, I really had no idea just how much this would actually turn me on! I think her looking at me the entire time as she sucked him just amplified my arousal.
After awhile, she stopped and turned her attention to me. Once I had removed my pants, and she had nearly sucked me beyond the point of no return, I had to stop her because I didn't want it to end so quickly. So I asked her to remove her clothes and lay on the couch so we could return the favor. Once she had done as I asked, I dove between her legs and began lapping away at her sweet pussy, as the young man started caressing and sucking her breasts.
In doing so, I was amazed at how wet she had become from sucking our cocks! It was almost as wet as though someone had already cum inside her! After lapping away the external nectar from her inner lips, I turned my attention to her clit, sucking it while gently massaging the inside of her with a couple of fingers. It wasn't long before she started bucking, and I knew that she was about to cum. The closer she got to cumming, she told the young man to give her his cock so she could suck it! Once she began sucking him, that was all it took to push her over the edge! As she came with such a deep intensity, she also squirted at the same time!
By the time she had finished, my face was drowning in a shower of extasy! I can't say that I've ever seen her cum that hard before.
As she recovered, the young man began cleaning her up with his tongue, I held her in my arms caressing her breasts while kissing her deeply.
Then she whispered in my ear "Happy Birthday", and I whispered back "You're amazing", and kissed her again.
After she recovered, she whispered in my ear again and said, "I'm not done with him yet", then she kissed me and told him to put his cock inside her while she sucks me.
It really didn't take long for all of us to cum, and yes, she let him cum inside her as she sucked the cum out of me!
When we had finished, and the young man had gotten dressed, she kissed him on the cheek and told him thanks for helping her surprise me for my Birthday. Then he left, and the two of us went to bed and drifted off to sleep, holding each other.
What an amazing Birthday surprise. I couldn't believe she actually did it for me!
(I'm pretty sure she liked it too.) 😉
