Sub surprising their dom

I (37F) have always been into kinky stuff and BDSM, and is submissive. But I have just now gotten a dom, a pleasure dom. The sessions so far are amazing, I never thought sex could be this great and I have the most intense orgasms and enjoys every minute. He is really great in all ways, and we connect on all levels.

I want to surprise him with pics, videos, assignments, stuff I do during daytime/work. So am I looking for advice and inspiration on what other subs have done for their doms, to show appreciation and their obedience. Or ideas on how to make pics/videos better, more fun, exciting.
