Threesome with 2 Guys

Q: My boyfriend and I have been playing around lots in the bedroom. Recently it was revealed through dirty talk that we both enjoy the thought of another guy in on the action as well. (Not with him, purely a fill all my holes and suck a cock while I take his cock kind of fantasy)

We’ve been discussing it for a really long time and want to give it a go! How do we go about finding said person? I don’t think he wants to let any of his friends in on it so I’m really at a loss as to where we start. We are in this together and fully committed, no weird feelings or judgement, just looking to fulfil this fantasy that we apparently share! (Ladies, be sure to talk to your man about his kinks... You could share some in common 😉)
