Sadly I was on the road... I saw the original post and as it was in the submissive couch area, and was a direct question to subs, I waited.

Now seeing the initial replies I could well have answered (or rather asked,) if threesomes were ever discussed in general and what expectations you knew your dominant had of you.

The conclusion that so many jump to... that trust or respect was broken, that some line had been crossed, does not take into account the nature of the relationship. It does not account for kinks, fantasies, or desires of the "used" partner. It does not take into account the level of service the submissive wants to give to please their dominant.

So as long as the concepts have been discussed and generally agreed upon, including situational limits (with strangers or mutual acquaintances,)

Yes indeed. Hot.
