The main thrust of getting it done is what I call "Seducing Your Wife". You will seduce your own wife and lead her to the fun that can be had. More on that later in the post.
I do 3sums- I started mid way this year with a bi FB of mine and have more then 20. Its allot of fun. I could give a car load of 'moves and ticks' and shit to use at bars and with random HBs and what not- the key here is, DUDE ITS WITH YOUR WIFE! This could make your relationship stronger and more fun and expanded sexually.... Or, it could make your relationship past tense.
Its your wife and not some random bar whore. Be sure that you know this is about expanding the RELATIONSHIP to make her and you have more fun and not some one sided 'just get off a new way' phase (for her or for you!).
Emotions are the key force . If she is drunk when she tells you she likes HB coworker- why not discuss it more with her when she is sober? "Baby, you brought a simile to my face when you said XYZ sexy things about HB coworker last night. The truth comes out in wine I guess...I do you still feel about X" Have a real convo w/ her about her feeling that way toward another women.
Get Rick H's interview. He talks about the bi girl mindset. She has a few things to come to terms w/ as a bi lady. Many fun items but a few social, personal and emotional ones as well.
She is a polarity responder? (NLP term not RJ's SS BTW! But who cares...) This can work out well in leading her- I'll share w/ you how in a bit.
Why have you 3 (you, wife, coworker) NOT gone out to dinner and talked about this (or felt it out) as adults? The answer maybe inner game and frame of mind stuff that you both need to deal with as a couple be4 the sex starts.
Is she bi for herself or bi for you? It may seem like one or the next- it can switch though once it gets real. I'm such a great lover that many HBs will 3 sum for me to make me happy when they are not really all about the pussy. If she does it for her and her alone- GREAT! You can get some of that fun and will it build form there. If she only does it for you or just a one time thing to see what its like...
Women go thought phases too- she may have missed out on the bi curious phase of college girl life and wants it now- if only to try on. She may visit "bi HB land" or she may stay. Be cool w/ it either way.
Does HB coworker like you too? No 3sum if not for that! Also your wife sees you FUCK ANOTHER LADY! It is a small shock IRL when it happens (good mostly but otherwise too)... As is seeing the girl you love cum from another's actions with her pussy. Get your heads right! Many people though can handle it and like that.
Okay- now to do the fun work!
I hope you can make her g spot squirt and have read up on the sex tips here and gotten the vids on being a better lover an being male multi orgasmic and such. If she is to do and get more out of sex- you best keep pace! For her and for your self! Two people growing together grow closer together...
Go and buy and read together The Ultimate Guide to Sexual Fantasy by Violet Blue ISBN: 1-57344-190-2 GIFT WRAP IT AND GIVE IT TO HER!!
You can read it together in bed (or before) and check out p 71 on 3sums and the NON JEALOUS ways to make it real and all it can be. Good book. More then just David S's vids to view together. Read it, FUCK HER GOOD, then talk about the book- you get logic and passion and emotion for you to play within her. A week into it and she will be more open in many new ways.
