edging the other wife in front of her husband during a soft swap — is this further than ppl normally go or are we mid-pack

genuine ask cause its bugging me. couple late thirties, LS 4 yrs, full swap, mostly UK club scene plus a few private parties. we met another couple at our home club, hit it off, two meets in we were comfortable enough to try a slightly kinky soft swap. the agreement was each husband would do orgasm control on the other wife — basically build her up and back off, build her up and back off, while the other husband watched. nothing penetrative, hands and mouth only. roughly 20 mins per turn. we'd talked about it loads beforehand because we've all done edging with our own partners at home but never in a swap context. it was honestly one of the most intense nights ive ever been a part of. watching my dh edge another woman while her husband watched her edge for him was psychologically a lot, in a good way. the four of us were emotionally wired afterwards in a way a normal full swap never gets us. now im wondering if this is just a thing kink-aware LS couples do regularly and im late to the party, or if we did something a bit more out there than the average couple realises. like is "edging the other spouse in front of you" a known move in the kink-LS overlap that we just hadnt encountered, or did we kinda invent this ourselves for our group. would love to hear from couples who do this regularly... how often do you do this, is it a special occasion thing, is it considered more "extreme" than full swap, and does the emotional intensity stay this high every time or does it normalise
