Not going to lie, I had the same approach to kissing and my wife shared that too. As we moved into the sub cuck scenerio and once I had seen in the moment she started to cum and was biting her lips, the guy was pulling her hair and she lost it. As she screamed, the guy pushed two fingers in her mouth after which she suddenly grabbed him and kissed him. It was a massive turn on. They kept fucking she was riding his cock and did not stop kissing and she did cum one more time. This was the time when I felt being a sub is the way forward and she does what she wants and I enjoy it.
