Not My Thing But Whatever

So my Dom is this guy who's a decade younger and he insists I call him Master. Today at work, he showed up unexpectedly to 'discipline' me for leaving a chart in the wrong place. He got all serious with 'his' little girl being disobedient. Really? A chart out of order warrants a spanking? I mean, sure, we're role-playing, but sometimes it feels like the joke's on me.
