Eating food with cum on it

I (32F) have only ever had any sort of intimacy with my husband. We’ve recently been exploring with each other sexually, which has been great. We had just discussed, not seriously, about me eating food for with his cum on it.

This morning, he gave me a cinnamon roll with cum. It wasn’t a serious request for me to do anything with it, but I took it to work with me in a container and then filmed myself licking and eating it when I was in my office. I sent it to him.

Now he is talking about how much he surprisingly liked that, and wants to do more play with that. Just curious on what others have done with this. I’m open to it. I couldn’t taste anything with the cinnamon roll anyway so I did eat the whole thing. 🤷‍♀️

Is this a kink? I want to look into it more but wouldn’t even know where to start or what to try next.
