We hooked up with another couple once on a cruise. Just kinda happened. They were our age, we got along while on the cruise. One afternoon in their cabin, one drink turned into 4. Girls take tops off to get sun on the balcony. Wife and I had done this before with others occasionally, no big deal.
Other hubby and I just chatting and chilling, girls doing same.
I don't know how or why but the girls, drinking, start sex talk. Turns out they'd "experimented" with another woman and with a 2nd guy. They preferred the mfm thing. My wife openly tells other wife we have a guy we see pretty regularly. I'm thinking WTF?...as we don't tell anyone we do this. But what the hell we're never gonna see these guys again.
Wives get talking about dick sizes. They talk us into naked, soon all four of us are naked, him and me hard. Awkward as hell for me and him. Girls start playing with our dicks, they decide to swap for oral....only for a minute... they say. We end up fucking each other's wife, happened pretty quick. The girls are super cool with it, me and him are like what just happened??
The girls are chatting like us guys aren't even there. How soon a guy gets hard again, how long it takes for a guy to cum, why do guys grunt when they cum. It was kinda funny. My wife telling other wife about our guy, how many times she'll cum in a night, how we enjoy when he visits, how often, etc. His wife telling mine about their experiences. 3 different guys, including dick sizes, one once, one a couple of times and 6 with the last guy. What they liked, didn't like and such. The girls did 99% of the comparing notes.
We end up doing each others wife again, more chatting. Was fun but was friggin weird. At least the other hub could relate to some guy having sex with his wife.
