Challenge for Authors

There's a particular variation on the cuckold theme I haven't seen written about very much, in which a man is "cuckolded" in the following way: he is in love with another man's wife, and together this couple dominates and humiliates him. For example, they might power him to watch and even service them in the most degrading ways, comparing him (unfavorably, of course!) to the younger, bigger, stronger and much better hung husband. Any authors out there want to take a shot at this subject, or does anyone know where I could find stories like this?
