Disclaimer: I'm Scandinavian, we have liberal sex culture and in my company there's no rules about getting involved with coworkers.

I (38F) work as IT consultant in a large company with several client companies. Recently I've been involved in a project where I've developed a huge crush for the client company's project manager (39M). We've connected outside work over our love for boardgames, beer and shared past of nerdy things (like attending LANs). I like him, he likes me, we're super flirty and all that.

He's married with kids, I live with my partner - but we're both ENM (ethically non-monogamous). I know this because I recently put 1 1 together after hanging around on one poly forum where we both participate. He even uses the same username and avatar he uses on some of the company systems. He doesn't know that I know he's poly, and there's hasn't been good moment to mention him that my partner doesn't mind me sleeping with others.

We're going to have afterwork beers and boardgames tomorrow, just him and me. I've checked the company policy that there's no mention about personal relationships with either co-workers or clients. Should I just get us both drunk and then just tell him I'd really love to suck his cock?
