How to reward a man sexually

What do you do for your man when you want to reward him? Looking for ideas that don't involve new lingerie, and that I can do tonight. I am 36 weeks pregnant. He doesn't like anal play, but does like being in charge. He also doesn't mind when I take charge every so often. He isn't super vocal, but occasionally will talk dirty. He doesn't like calling me dirty names though, because he is worried about going too far. Occasionally we have broken out the cuffs and toys, but again, he doesn't like the fear of going too far. We have gone too far before, but it was always because I thought I could handle more than I could. He always blamed himself though. He works super hard and is always physically exhausted when he comes home from work. Half the time his legs give out before he can even cum. So I want it to be easy for him. But also something that will make his face blush when he thinks about it the next day. 😉
