Surprise threesome? Always dangerous.

Since you're posting here I'm guessing you lack a slutty single friend. Consider just hiring a prostitute and not telling him. Your guy should be fucking the other girl with a rubber either way.

"talking clean and honest"

No, you won't find any help here.

You would really do that for me?!?

Why not hire a hooker and tell him! That would be brilliant!

Go for an Eastern European hooker because those girls like to take it up the asshole! Or "get breech loaded" as some of us say!

Try adult friend finder.

Craigslist can, with some patience, yield some fun. From your comments, you'd want the mw4w section

I can actually confirm georges comment re: Craigslist. It is panning for gold though. Lot of fakes, flakes and pic scammers.

Honestly, this is one of the last places you should go to looking for a single female for a 3-way

Just hire a hooker. You'll spend 3x the money searching strip clubs. You ain't gonna find any willing women here. This is a customer based site in case you didn't realize that.
