Wonderful wonderful story!!So why didn't you join in? A women loves that attention and their is nothing sexier than have two cocks servicing you. Have her suck you while she's being fucked or vice versa. Seduce her and both of you undress her and partake in the foreplay. It will be very erotic and most probably a huge turn on for you and a definite turn on for your wife. Just a side note on how hot it can be to have your husbands be part of your fantasies come to life.
My husband was taking some photos of a tryst I had. He an the bull had worked me over pretty good up to this point and I had already cum several times. My bull moved me to the bed and mounted me and was driving his dick into me from tip to balls methodically. I found myself with my legs up in a big V so he had full access to me and my eyes where closed. All of the sudden I feel my ankles being grabbed and open my eyes to look up and see my husband straddling my face with his cock hanging down in my face and he had grasped my ankles and pulled my legs back and open to give the bull full access to me. That angle with my hips rotated up makes me crazy and he just looked down and fed me his cock to suck and and said to the bull "pound it" which he absolutely did. I never came so hard. I was totally vulnerable (which oddly really turned me on) and at the same time felt so sexy with my husbands dick in my mouth and my bull fucking me for all he was worth. I felt absolutely and completely sexual. It just made the experience all that more a turn on to have him do that. They changed positions and I flipped over and gave my husband my pussy from behind and my bull my mouth for the next round. This went on for almost 2 hours until they both came- one on my tits and the other in my pussy. It was one of the most exciting nights I've had because it was one of the first being shared in a MMF and I still think about the erraticism of it years later.
