I had a session in the Spring where the domme did that after -- posted a picture of herself in the dungeon post-session and saying how great the session was and what a good time we had. The session was great, and her post made it even better. Also having the picture of her in the same outfit and in the same space.

I sessioned with her again recently, though, and no post after, and I found myself a bit disappointed by that! You can't have everything.
