Hotwife Seeking a Girlfriend

We have operated in a fantasy world for years. We have incorporated cuckold fantasies and stories into our sex life and recently my wife expressed a desire to find a girlfriend. I am completely supportive of her and am excited to expand these fantasies to the real world. But I am curious if this is even considered cuckolding. To me, it still seems the same as traditional cuck/hotwife relationships, but I cannot seem to find any content on the subject. The dynamics are the same, I am denied/locked and she is free to explore and experience. Does anyone have any advice or experience in this area? Are there stories out there? I would appreciate additional perspective on how a hotwife & girlfriend interact within a traditional cuckold dynamic.
