What next?

I was scrolling through grindr the other day, when someone familiar caught my eye, this guy I had a crush on that used to work at tje same place as me was on there, well, him and his husband. They're looking for a third to take into the bedroom, and I'm all about it. The only problem is I got as far as for the guy to say that we could try and plan something, but I don't know where to go from there, I asked yesterday what all they were in to, but I haven't heard back. Should I keep pushing, what else should I say, I really find them attractive and would love to get used by both of them, I just don't know what to say next.
