Monogamous Orgy

I'm a 46 year old happily married woman. My husband and I have been together 25 years and he has been the only one who has ever penetrated me. I would never dare break my marriage vows... except in my fantasies. When my husband and I are making love then anything goes in our fantasy world. Gorgeous strangers suddenly appear and join us. Every position we find ourselves in invites different combinations of bodies, mouths, and warm, wet nether-regions. When my husband is moaning I imagine that it's not just from being inside me, but perhaps what he's simultaneously feeling inside him from one of these mysterious strangers. Our mouths get no rest, our bodies are entangled with others' hot limbs and torsos until we both climax and surrender back into each others' embrace. We remain true to each other, but our fantasies spark a fire that sometimes only intimacy with strangers can fuel.
