Looking for suggestions on how to improve our situation [cuckold] [humiliation] [dom]

For those of you who haven't seen my other posts just know that I tried to post them on here first but wasn't allowed to because of my score or something dumb like that but feel free to read into them or just take this general summary if you prefer…. basically I was with my bf and we moved into a new place with a roommate, I cheated behind his back for awhile then we cucked him openly and he took awhile to adjust. Now that we got past all the objections he has been caged for nearly 10 days. He swallows his friends load every time we fuck and even let us try a cuck 69 which we have done every night since! I love having him taste me while I take his friends superior dick ?? it also really turns me on that his balls are basically resting right on top of J's face ???? I'm hoping to get some suggestions on how to continue spicing things up and pressing farther into the humiliation side of things ???? we love to make him beg for his cum and other things like that and I plan to keep his dick caged for as long as I can 🙂 anyone have any suggestions for things to try or ways we can entice this to keep going??
