Our first step into cuckolding happened

We have been talking about the possibility of this life style for a few years. It started with me asking her about her past sexual encounters and experiences and her noticing how excited it got me when she spoke of these times. So we started playing a fantasy role of her with other guys, it started slowly with having a threesome talk, then it morphed into having a threesome and me getting up to shower and walking back into the room and seeing her riding his cock. Then my next fantasy was walking in on her having sex when I came home form work (still hoping to make this a reality)

Anyway, we have been getting pretty close to taking a leap, starting to search for potential opportunities. Recently we were in Maui on a wonderful vacation.
One night we were in the hot tub, it was a unique secluded hot tub surrounded by lava rocks, you really could not see into it, unless you came to the stairs to walk in. We visited with a few other people and there was a guy there that was very personable and my wife and him seemed to laugh with each other. I truly thought nothing of it until one time I got up to get a some drinks and came back and they were the only ones in the hot tub and truly laughing with each other.

That night we went back to our room and had some hot sex as I was whispering in her ear about maybe sucking his cock at the hot tub tomorrow night. She blushed and said “you would like that wouldn’t you?”

Fast forward to the next night, back in the hot tub, similar scenario but some young kids were hanging around way too long the three of us laughing getting to know each other better. I went and got some drink again and by the time I came back the kids were gone and he was speaking quietly to my wife kneeling in front of her in the tub. She saw me walk in and he quickly backed away.
She said out loud “Seems Jim here would like to fuck me without you knowing” Jim immediately apologized and started getting out of the tub. But my wife said “Hold on Jim” “I won’t fuck you, but let me see what you have first”
My jaw dropped. I didn’t know what they spoke about when I was gone (she told me later) but he looked at me confused. I did not know where this was going to go but I was ROCK HARD>

He say on the edge of the tub and lowered his shorts to show an average cock, with the hair trimmed very short. It was getting hard fast. My wife looked at me and smiled. Shrugged her shoulders and asked “what do you think honey? Is it good enough for our first?”

My mouth was dry and my heart was pounding.

She glided across the tub and looked at his cock. I though she was going to suck him. But she just looked at her first new cock in years and I could see her hands shaking.
She took it in her hands and slowly stroked his cock.She looked right at me and said “I am so horny sweetie you better fuck me after this”

I watched her stroke his cock slowly, he started moaning within a minute and said he was going to cum right away. I watched as my wife made another man cum with her hand in about two minutes….. watching his cum splash against his stomach. She looked at him and asked “Did you like that?” Jim replied “That was the hottest thing I have done in a long time, thank you” He asked about tomorrow could we try again?” (he had to try).
My wife just said “we have gone far enough for now, thank you Jim”

I watched him walk away and my wife looked at me and said “you better get me to the room and fuck me or I am going to follow Jim” I thought about it for a brief second, but grabbed her towel and said “Lets go !!”
