Cuckqueaning, also known as reverse cuckolding, is when a man or woman 'cheats' on their girlfriend/wife to humiliate her. This can also be combined with orgasm denial or a larger denial of sex or other activities that the Dom is now getting from someone else. Obviously a bit of a mind fuck and not for everyone.
I've talked about this with a previous sub that suggested it and my current sub, with whom I've brought it up. Just wondering if anyone else here has kicked it around and the idea of combining it with OD.
