I picked the third option, closest to my experience.
KK’s first three open hot wife encounters were more or less solo. In large part, they were revenge, retribution based as retaliation for an affair I was engaged in.
The first encounter was back-to-back with a guy KK picked up in a local bar - a backseat car-fuck. That night (actually wee hours of the following morning) KK blatantly confessed the encounter, proclaiming that going forward she’d fuck any man she fancied. The following afternoon, KK had the guy visit at our home, locked me out of our bedroom, then fucked his brains out.
The second hot wife encounter was similarly solo - KK went on an overnight hotel date with a colleague/acquaintance rumored to be “horse hung,” an exploratory move on her part, in the same retaliatory mood.
The finale was a holiday gang-bang with six men - it was intended to be an MFM with two guys she connected with on the internet, but it spiraled out of control. That happened in our hotel room, when we were on holiday travel - I was banished from the event, kicked out, and left to drink in a local strip joint to suffer. I got the aftermath, cleaning up the gigantic mess in the hotel suite, and dealing with a hung-over, fucked out wife.
What I consider our first “official,” open hot wife encounter was an unforgettable event. We were traveling on business/pleasure. KK picked up a stranger in the hotel lounge, while I was in our hotel suite concluding a business conference call. Just as the call was winding up, KK showed up in our suite, with her conquest in tow. I watched the whole encounter, up close and personal. The two of them fucked like I wasn’t even present in the room.
