Hey Guys,
Recently one of my and my gfs mutual friends Missy bought her a book of sex stories for xmas.My GF has been with me for 10 years, and I was her first. Her friends know this.
I was a little freaked but didnt think much of it. Then a friend who mixes a lot asked me if I was bothered by the gift. I said no. She replied "even though missy is bisexual" ? I didnt know this, but pretended I did, and acted cool with it.
That night my gf and I were fucking, and she asked if I ever have fantasies I am ashamed of. I said yes, and she said not to worry, she loves lesbian porn but it doesnt mean she wants to be with a woman.
Anyway, next day I noticed that here underwear (very sexy) was new. The next day I found a massive dildo in her draw (9.5 girth by

, lubed up and obv used by my gf.Along with it was also a lot of feminine but sluttish style new underwear.
That night my gf wanted to read the sex story book before we had sex. I got angry and asked her to put it down. She accused me of beign jealous of anyone she hangs with. I said no, I'm only jealous of missy.
She said I was silly and asked if I thought something was going on with Missy. I said I wasn't sure but that it was inevitable that they were going to have sex. She turned away from me, and didnt answer that. She simply said asked why I was so upset about the book. I asked who got her the sexy underwear (Im letting her keep the dildo secret) and she said missy.
She told me to stop being stupid, that girls buy each other underwear and things like the book and that I was a prick. She still wasnt looking at me and I said to her - "do you think missy hasnt got off on the idea of the kickers she bought you being covered in my cum and your pussy juice after a good hard fuck??? Do you honestly think she hasnt fucked herself sensless over that - she is bisexual you know"
My gf said I was probably right but she had been niave. I then told her that Missy wanted to fuck her and hard and she looked at my gfs body the way I do.. I vaguely hinted that missy had talked about my GF in a very sexual way to me (my gf didnt question this, even though I made it up). My GF admitted that Missy was slightly attracted to her and she knew it but it was too slight to matter.
She then said she had been very niave and felt she was being groomed by Missy, and that I should be angry as it was no different than a guy wanting to bed her. I said I had resigned myself to the fact that they fancied each other too much to stop it happening (I made this up but she didnt question it) other than to say that she felt manipulated.
She never looked at me during this conversation. I drifted off to sleep, and she woke me to say she was nipping out. She wouldnt say where. I discoved she had left her phone, and had called missy just before she left (missy must not have answered). My GF was back very quickly with takeaway and nothing much was mentioned other than she said I was very selfish to tell her that missy wanted to bed her, as she felt awkward around her.
I checked her other phone today and discovered a lot of messages between them. None that were exactly wrong, but borderline:
"hey Missy, gonna go to bed soon, but having a read of that book in the bath first xx"
"hey GF, good to see you for lunch today, you looked really good, glad to see you are making an effort for me"
"Hey missy, thanks to the book ghands made me come twice last night. Thank you so much"
My GF has also said that Missy is very kinky sexually, but will not tell me how as it is nothing to do with me, and that they do talk about sex a lot, but all that missy knows is that I am good in bed"
Basically, are they lezzing, preparing to lez, or can I tip things over the edge" My gf is so sweet I cannot believe what is going on. I cant understand why she called Missy after our argument, or left the phone there where I could see she had called missy. She didnt go and see her ...
Please guys, I realise this sounds messed up - but I want to know - are they lezzing already or is my gf looking for permission. Why didnt she answer when I said Missy was bi (something I shouldnt know), or that it was inevitable they would fuck?
