I'm going to be involved with one or two girls who are interested in just having fun, not relationships. So this is probably going to be possible.

Only way I can think of right now is how it nearly happened to me. Basically one girl wants to see me but other girl already is, and I make a joke "I can't I'm already out! Unless you're interested in a threesome, hahah..." and she said that didn't bother her at all, so she came out.

(If you're curious - that one didn't happen because the 1st girls' friends showed up, so I let her spend time with them because we'd all be together later, while I entertained the 2nd girl - big mistake - these days I know how important it is to keep the spark going. The 1st girl thought I was more interested in the 2nd girl and that she should leave us alone, and made an excuse that she was going to stay with her friends. Later I found that's why she didn't come home with us - but I had a falling out with the 2nd girl before it could happen again)

The only other reason I've been involved in to see it progress (and this was a very chance thing, so it doesn't count) I was with a group of friends who were on a bed and decided to somehow have a "orgy" as a joke, people tickling each other etc. and one guy had his girlfriend and another girl start doing stuff, and it gradually escalated as the girl could see the girlfriend was ok with what she was doing, and yeah they had heavy make out sessions in front of us and now they all regularly sleep together as a threesome.

only thing i can think of is a dual induction massage as detailed in 'the game'

or obviously if 1 girl has bi tendancies you and her actively go out looking for a gal for a 3sum!

Girls who do not have bi tendancies are in the rareity in my experience

a lot more common than you would think mate! actually most girls have bi fantasies but wont admit it.

i was with one girl for over a year before she admitted it one night when she was drunk. couple of weeks later we met a girl online and fucked.

getting one girl who is bi curious is more than half the battle. then you can go on line as 'couple looking for fem' in social networking/dating sites, post an add and bi lassies will find you! guaranteed!

my gf of the last 3 years admitted to me couple of weeks ago she had a dream that me and her 3somed a girl. shes saying it was just a dream and she doesnt know if she would do it but i can talk her round now and its a matter of time!

Hehe - notice the "NOT" in my statement. All but a few of my female friends like looking at other girls and doing stuff with them. Those are cool stories though.

think of sly ways to get her to think bout it too. id suggest makin something up with NLP. emmbedded commands etc.

scientific studies have shown women have far, far, far more bisexual tendancies than us.

good luck
