Teasing my boss [MF]

So my boss and I have flirted back and forth for a while. Little dirty comments, sharing past party experiences, wearing tight clothes during meetings. As we work very close 6 days a week we were bound to become closer. However it’s started to consume my thoughts. I’m 23. He’s 40 ( which in itself is a major fucking turn on to me). And he’s my boss. I can’t stop fantasizing about him doing terrible things to me. Today he asked me if I completed a few tasks. After I told him I did, he casually said “good girl”. Being majorly submissive this immediately made me dripping wet and flustered. I told him in a teasing way ” you can’t call me that” .

We tend to motivate each other to get to the gym. So I decided to take a risk and send him a progress pic ( panty pic with a bit of underboob). As it was over text I can’t be sure but I think he definitely enjoyed it. All I want is to have him bend me over his desk and fuck the shit outta me. It consumes my thoughts and dreams.
What little things drive men crazy? Any suggestions on how I can tease my boss mad?
