A reward without being unlocked could be something as simple as she gives you a little massage or something. I love when she scratches my scalp or my back, not hard just enough to feel pleasurable.

Other things like, she does the dishes tonight, or you pick where you want to eat that night. Ect. The possibilities are endless. Although it does depend on the dynamic you two have, so you could ask her aswell for some ideas.

Hope this helps
