I like the idea of being raped while my husband is forced to watch. It's not a humiliation thing, just the look in his eyes as he watches me being used and filled. He's excited seeing his wife naked and active, at the same time he's concerned for my well-being. I think he fantasizes about threesomes but would never do it, just like I fantasize about a lot of sexual things I would never do. This way neither of us has a choice. He sees a stranger stripping me, groping me, fingering me, moving inside me, and tensing up as he cums deep inside me. He sees me laying there with the stranger's cum oozing out of my used pussy, and knows I've been thoroughly taken.
