Helping My Husband Live Out His Filthiest Fantasies

My husband and I have a very open relationship. We help each other embrace all of our kinks. Over the years we have grown and accepted our (mostly his) limitations. The biggest of which is that his cock just isn’t quite adequate to make me cum. So as we have developed sexually he has fallen into his role nicely. He buys me toys big enough to actually make me cum, and doesn’t let it effect him. Eventually we learned he much prefers to be a submissive locked in chastity, and to have his asshole fucked while he watches me get pleased. Lately he has been keeping himself in PERMANENT chastity, and really been begging for me to bring another cock into the mix (not just a toy). So, I found one. I make friends with a guy at the gym, explain our dynamic, and he agrees to come play. Once he is there I lay out the ground rules for him that both my husband and I have. Mostly being that I am the only one who can humiliate him, and our new bull CANNOT eat my pussy.
