So my newest SB is a beautiful young black girl, 24, athletic and very horny. She loves receiving oral more than giving it. The other day she texted me that she wanted me to eat her pussy right now. Normally I would say come on over but I was feeling under the weather so I couldn’t. She then asked me if I had any friends like me who were available. I don’t know about you guys, but I don’t know anyone in my circle of friends who is doing this and it’s certainly not something I want to share with them. Then she asked if I would bring a guy one time as it’s her fantasy to have 2 older white dudes licking her pussy at the same time. I almost laughed because I have never imagined being in that scenario. But I have many times imagined 2 girls and me, but she wasn’t into that. I do have a different SB, Latina girl who said she wanted to try with another girl, so now I’m trying to find someone who she’s attracted to as well so we can schedule that.  
So, have any of you guys had 2 SB’s at the same time? How did that work out?

Ok, first, two guys and a girl is not a threesome. It's a gangbang.  While two girls and one guy is most definitely always a  threesome.  Hey, it's not MY rule. It's International Law! :p  
.
Next, I never want to be part of a gangbang. It's just not my thing. So I'd try to show her that a guy and a hot chick licking her pussy looks exacxtly the same in a dark room as  two guys licking her pussy (especially if the 2nd girl wears a strap on - which admittedly can be a bad idea).  
.
Third, if you are ever going to be successful getting her into a SB threesome (and I have not so far, except for pro's in Amsterdam, Vienna, Aruba and Curacao), then SHE needs to find a freind that she wants to bang (or has already) and bring her over.  Let her decide if she wants to share the sugar,  if possible, so you aren't defaulted to pay double. If necessary, agree to pay the other SB something, but I suggest NEVER more than what you provide to your SB.  
.
Why let her choose the second girl? She will ask someone that she knows, she's attracted to, and who's likely aware of and ok with her sugaring. If you try to pick someone to add to the mix, you will have to negotiate addtional sugar directly (which could be costly), and your curent SB will likely tend to be jealous or threatened that she will be replaced, and may not be attracted to her (which means she has veto power and you may still have to pony up sugar to one or both).

As posted elsewhere, I have had several threesomes with SBs and currently have a couple of threesomes ongoing. The SB always picks the second SB. I pay them both the same amount. I know from prior experience that sometimes the primary SB will take a cut from the payment to the second SB, but that is their business. I had one SB suggest a second guy but I told her that I have one ironclad rule: no other dicks in the room.

I have had conversations with women about threesomes where it is definitely necessary to specify whether it is MMF or FFM. And yes, we referred to them as threesomes in each case.

If you try MMF with Herb - you may want to handcuff him the deck railing outside just to make sure there are not any surprises...

Multiple sex partners are cool as long as there is only 1 Dick, mine.  That’s my only way I can have a 3 way or whatever you want to call it.  

It's really easier than many guys make it seem.
By selecting a girl who lists men/women in her profile you are guaranteed she has a g/f...
By selecting a hot girl, you are nearly guaranteed her g/f will be hot...
Let the girls lead the action, no need to plan in advance...
I always ask for and receive a discount...

In my experience it's rare for two hotties to be a couple, yes it happens, but it's a LOT more common for there to be one "lipstick lesbian" and one "bull dyke" than it is for two hotties who are "bi" to be together.

So strange how people's experience can be so different...that's good though.
I have always found that hot bi-girls (not lesbians...totally different story) appreciate another hot girl as much, if not even more than me.  Their standards of acceptability easily exceed mine.  One girl is usually dominate, but that hasn't affected what the more submissive one looks like.
Now, of course, my sampling is 4/4 so I'm not to run and out an publish a scientific paper - LOL

and very rarely were their GF's "hot". I have also known a LOT of lesbians, and as I said before, most Lesbian couples seem to be "one hot, one not" lol  

After reading this thread I am motivated! One of my SBs is a wonderful 20yo I've been dating for a year and a half.  She's definitely bi and I think has at least one GF currently.  Don't know why I haven't asked her for a threesome yet, but I think I will when I see her next week.

They are looking for the stimulation...offer her MVF (male/vibrator/female).  Just prep her gently for the Greek and then use the vibrator (make sure you get an Amazon 4+star rated one) for the male counterpart.
Not exactly the same, but she will still thank you anyway!

All of my legitimately bi sugar babies don’t have attractive friends. They never go along with any of my choices. I always sense a bit of jealousy if I pick the girl. So I’ve yet to have a threesome.  

One of my SBs have asked me for a threesome.  She told me to just find the other girl.  I’m thinking about it....

SB I've seen for a while, texted me and attached a pic of her and her hot friend, said they were bored and wanted to stop by.  Who was I to say no.  They were not into each other, bummer about that.  But otherwise a pretty good time.  Just had a bi/lesbian lady message me and wanted to know if I wanted company and a good time with her and her girlfriend, who on her profile says she loves.  Too many tatto's for my liking, and she never even requested to see my private pics.  SA is a site where you never know what is coming along next.  

My long term SB asked me to get another SB for a threesome. It took sometime but eventually I found our third. I drank too much wine (I was nervous) and had performance issues during the event. We haven’t done it again since. She’s asked about it but I’m not that interested after the last time.
