Bisexual husband

My fantasy is that my husband is secretly bisexual. When I find out (maybe finding him in a compromising position with a cute, young man) I'm very surprised, but also very turned on. I decide to join in, and they fuck each other as well as me. I get so horny watching them make out and suck each other. They go down on me as well, and we all have sex until we all come. Afterwards, we all agree that we should meet up with the guy more often - friends with benefits! Maybe the husband and I could even go out hunting for cute guys together?
