Being a voyeur, I prefer to keep things at a visual engagement, the select few encounters that I've enjoyed (and they as well) with couples and single females has been erotically charged and incredible.
That being said, my recent fore into the world of what I call assisted submission was fascinating and an incredible experience. Some would call it cuckolding, some 'hot wife' or even fantasy fulfillment. None of those terms are completely accurate in all cases which is why I have come up with the 'assisted submission' term. Either way, I go home at the end of the encounter and am not heard from again unless you decide to contact me.
As always, sensitivity to the wishes of those I am participating with is a foremost concern, so I will relate my recent scenario in the most generic sense, hoping to still capture the essence of the encounter...
