How to ask coworker if they want to hookup during breaks?

Hey!

So like the title says, I have a coworker and a different site than the one I work at. Whenever I go there for work orders this coworker loves to say hi and chat me up. Having a hard time deciding how and IF I should ask them if they’d like to hookup. They’re gay also so that’s not an issue.

Not really looking for LTR but wouldn’t mind some liquid lunch every once in awhile and not sure how to bring this up professionally or whether it’s even worth the risk 🤣
