many different parts this kind of scene takes a sexy mature white women special kind of relationship to make it possible. I really don't think that it's the same for every couple though. I get something out of the temporary opening of the relationship. part of what I get out of it is obectification -- the 'use' of my wife for my visual pleasure at the momentary expense of her fidelity and relative safety around our relationship. there's a lot of thrill there, somewhat of an exercise of my ownership of her. another part of it is the thrill of having an outsider join us for sex. more can be merrier after all. also, in the context of a mmf scene, there's the obvious homoerotic possibilities and tensions. taking the opportunity to get off with another guy in the company of your woman (lover, wife...) is hot, and can be especially hot for guys who don't consider themselves bi as it stretches the boundaries of their sexuality. double penetration scenes have lots of very intimate m/m contact, especially where both cocks are in the same hole. I've met quite a few adamantly 'straight' guys who enjoy going down on thier mates after anohter guy has worked her pussy, not really my thing but I get off on seeing my lover suck cock - to the point where I get enormous craving to do the same. there's also the 'service of the woman' aspect of this kind of scene. similar to the exercise of one's ownership and use of the woman, there's the ownership and use of the guest man. I very much enjoy leading and directing another guy to perform at the pleasure of my mate, discreet webcam chat however that I very much enjoy sexual objectification too. I don't think that covers everything for me, but that's some of it for you. Anything sound familliar to you considering your experiences?
