KK and I have had a few experiences in this area, outing, and being outed, or close-call.
Our first was early in our married life - we were still attending church then, driven by KK’s upbringing and ritual. We’d been married about 8-months at the time this occurred. Around the six month mark, I was trying to spice things up, from pillow-talk to porn in print and VHS, as well as adult theaters.
One evening I convinced KK to go across town to a movie theatre showing the “Story of O,” then X-rated and controversial. We got tickets at the window, went in, and waited in the lobby. To our mutual shock, we ran into another couple who attended bible study with us, Jeff and Michelle. It was titillating, shocking, and embarrassing. The four of us made uncomfortable small-talk while waiting for the doors to open and be seated. We ended up on opposite sides of the theatre, and didn’t run into them again until Sunday services. It was really, really awkward. Things remained awkward for weeks. The four of us finally got together for a casual dinner one Saturday, including wine. That led to an attempted, but disastrous and abortive soft swing encounter, starting out with same-room sex, until we tried swapping partners for a make-out session. KK got absolutely enraged when she saw me kiss Michelle, while Michelle had her hand down my boxers, trying to fondle my cock and balls. KK ended the session with a temper-tantrum. We never saw them again - they simply stopped coming to church. Eventually we did too.
We’ve also experienced men we know in the community, including pastors, business owners, prominent leaders who responded to KK’s Craig’s List, AFF, AM and similar posts or profiles, looking for sex with a hot wife or cuckoldress. We have slightly different takes on this - I think it is kind of hot, knowing that some acquaintance finds my wife sexually attractive and desirable. KK’s a little twisted, often fantasizing about controlling or blackmailing them, using sex as a weapon. Long before we started dating, KK had an affair with a married youth minister in her church - it was originally “marginally consensual” on her part. Since that affair, KK has often fantasized about sexually enslaving prominent, powerful married men, off-limits otherwise, but under her control, the combination of desire, lust and fear of exposure.
