Chastity and orgasm denial discussion

Hi all and a happy new year. I’ve got a question regarding milking. Can you get milked without any anal stimulation involved? I’m asking because of something that just occurred to me. My cb6000s is locked, but I only ejaculated five days ago. I had quite an intense play session with my wife and stayed locked the whole time. While giving her pleasure, I could actually feel what I thought was precum coming out. It wasn’t exactly an orgasm, but it felt good. The fluid was clear and slippery like precum, yet I’ve never noticed it exit before. This happened four or five times while no anal stimulation was happening. Later on, she used a dildo on me for about 20 minutes, and during that time, I had two or three more of these episodes. Has anyone else gone through this? What is it?
