Help a sista out!😜

So me and my boyfriend have great sex. He's very sweet and always thinks of me during sex. He often jokes around and says " I do all the work during sex." I feel bad and I want to surprise him by giving back. Any ideas on what we could try? I do get on top and he says likes that but he likes to be the dominant one. I want to go all out and do the work next time we have sex though.
