One night I was sitting at home and got a phone call. I answered the phone and my daughter told me she got married. She and her childhood best friend were in Spain and got drunk professing their undying love and got married. I, of course, was happy for them and saddened I wasn't there to see my only child get married and help her plan her big day, but I kept it to myself and cried with them in their joy.

About a year later my girlfriend Sue and I were shopping for a present for their anniversary and she asked me to marry her. Of course, my first call was to my daughter telling her the news. She was happy and told me she and her wife wanted to invite us to join them on a cruise for their first anniversary. We were on speaker phone and before I could ask her, Sue happily accepted.

A couple of weeks later we all met up at the pier, got on the ships, and enjoyed a two-week cruise. On the day of their Anniversary, my daughter said, "You know what would be cool? If you two got married today we could all share the date."

We weren't sure we could but somehow they managed to get the captain to agree and a few shots later we bought dresses and got married. We spent the night dancing and drinking and loving the fact we were all together. While we were at the bar, my daughter and wife were chatting as my daughter-in-law came out of the ladies' room. We walked up and asked them what they were talking about, and my daughter said. "We were talking and it's not fair. You've had sex with my wife. Poor Sue must feel like an outsider."

I asked what she meant she said she wanted to fuck her stepmom. We all laughed it off thinking she was joking of course and ordered more drinks, and some water because we were all pretty wasted already. Looking at my wife I can see why she made the comment. At the time, she had grown her beautiful red hair longer and she was wearing a green dress that matched her eyes and no bra for her perky C cups, showing off her cleavage. Enough that, if she bent over one, or both her breasts, would be exposed.

About an hour later my daughter-in-law came up to me and Sue and said, "Nikki wasn't kidding that we had fantasized about it several times.

Her comment didn't really sink in right away but my wife looked at me and said, "Up to you."

I was thinking 'Wow. She has a kinky side. I wonder if she would do it'.

We all talked and went back to the cabin where I kissed my wife while my daughter-in-law pushed Nikki towards us and pulled me onto the chair to sit next to her and watch. Both of them were nervous, both were drunk, and both looked very pretty in their dresses.

After about the longest twenty seconds I can remember they kissed. A peck to star, then slowly getting more into it. Finally, their mouths opened until she untied my wife's dress. It fell to the floor exposing her beautiful breasts and pale erect nipples, My daughter-in-law looked at her and commented, "Wow. You're one lucky lady".

I smiled and looked over at her to say thank you and noticed her nipples were erect and poking through her silk dress as well. Unable to hide my own reaction she quickly commented on mine and groped my breast saying, she knew I would enjoy the show and kissed me deeply, taking my focus away from the show my wife was putting on.

As my dress fell to the floor I looked over to see my daughter totally naked, not the first time mind you, but outside of tanning and changing, this brought a whole new context, although I was too distracted by what was happening to me to think about it.

My daughter-in-law took my hand, led me to the bed and pushed me down, still kissing me> I undid her dress and pushed it down exposing her beautiful perky B cups and caressing them. I felt my wife falling to the bed next to me as my daughter leaned over and kissed her wife, commenting that it was so much hotter than they had talked about as she removed my wife's panties and dropped to her knees.

My wife's eyes rolled as her back arched and she let out a simple 'Oh my god' before grabbing and kissing me before my own panties were being tugged off. Lifting my hips and kissing my wife, it wasn't long before we were both taken right there and she orgasmed while smiling at me. She got up and pushed my daughter on the bed next to me and my only thought was 'Oh my god' she is going to see me orgasm. I could feel it building but I fought it. At that moment all I felt was embarrassment and arousal. I didn't know what to do or what to think, as my wife started licking her. I couldn't believe it but she kissed me. I couldn't hold it anymore. I moaned and climaxed with her tongue in my mouth. Yes, it was the heat of the moment but it sent me over the edge.

I quickly got up and threw her on the bed and dove between her legs showing her all the lust I was feeling in the moment my wife reached between my legs and felt how wet I was, and how deeply I climaxed, and kissed me.

I had so much passion in that moment I didn't realize the taste on her tongue. We just kissed and I told her I loved her before going back between my daughter-in-law's legs and making her climax. Before they started attacking each other my wife and I went into the shower to clean up only to be joined by them and we fingered and kissed, making our wives climax before going to bed and passing out.

We all woke up in a naked pile on one queen-sized bed, half remembering the night before. We all just looked at each other and talked about it. My daughter and I were both ashamed at what we did, hoping the other wouldn't remember the kiss, but of course, our wives were not letting it go, commenting on how hot it was and how much it had aroused them.

My wife leaned back into me as she let the sheet fall and let out a moan exposing how damp she was just talking and thinking about it, and took my hand and placed it between her legs. I commented on how everyone was sober and asked her if she was sure. she said, "Sober or not,we all fucked already who cares...."

Kissing the back of her neck, I started teasing her clit with my daughter-in-law following suit on Nikki, both of them humping our fingers while facing each other. We pushed them close enough to finger each other and it wasn't long before we all became a pile of naked lust once again.

Three days later the ship docked and we disembarked and went home, my new bride happy to be with me and me with her. One would think because of the shame of it all no one would speak of it again, but the truth is that it comes up often between my wife and I, as well as my daughter and her wife, and even Nikki and I, wondering if we will ever have the nerve to do it again, or worried that we already went too far.
