Should I Rock His World?????

My co-worker and I spend nights together at his place and he is all over me each time. I'm no prude, but everything in me is saying "girl don't let him in," so I don't! He has given me amazing oral several times and I returned the favor once recently...and now I think he wants more AND I'm a little curious. Heeeelllp...should I explore our sexual chemistry, or follow my gut with this one? O, did I mention he's my boss 🤷🏾‍♀️. We don't text, no small talk...just invites to come over. Ok, now lay it on me folks...
