My boss's plaything?!

Ok so me and my kinda boss recently started hooking up and hanging out. I always had a crush on him and I'm not sure if I should continue or put a stop to it? It's quite fun but I've never done anything like this before (I'm a virgin to make matters worse). We have both agreed that keeping it a secret would be better for both of us. Am i setting myself up for something bad to happen? HELP ME eve??!!
