I'd agree Sir Russell, if he just surrendered his wife to another man (totally non-con and without letting her know) it would soon step over into real rape, and it could wreck the relation outright - and very few men would want to do teh scene like that. It's a potent fantasy to very many people (me included) but I guess it ´would be sensible to do it with some kind of secure means of breaking it off, or at least controlling it. Esp. if you've never done it before.
