Is 3sum fantasy to reality really bad?

I 1st got met my girlfriend at work, she was above me and also a lesbian, we spoke daily and had laughs, i knew she was a lesbian and that i could never have her but that was even more amazing wishing i knew what she looked like under those sweet clothes. One night i stopped in a hotel and we were chatting on facebook, telling of our past, she told me she once had a 3way with a lady and a bi guy, He didnt touch her only her friend. but that turned me on something crazy, At the end of last year, she told me there was a 10% hole in her life that only the right man could fill, other then that she is all for ladies, well it turned out that was me. We got together, took it slow, and as you all can see, has the most amazing body. i never fail to cum. now we have been together 6 months, I mentioned a 3way to check if i was pushing any boundaries and her face lip up. oh dear i thought, my fantasies have always been imagine based only, she told me she will try anything once just so she can say she dont like it. And i think she will stand by that because she is willing to do almost anything. She told me the thought of us taking on a woman in a 3some excites her and the thought of me hammering another ladies pussy makes her tremble and wet. So i agreed, sometime this year we shall try it, i will take a leaf out of her book and try something. The nervs is killing me even now, the thoughts of another woman touching this woman im in love with makes me feel sick, yet the smallest thought makes me horny, its a strange feeling but i hope i can hack it. We will start off with holidays, maybe buy a escort of our choice.

She told me a story last month about when she was 15 and she was sharing a bed with her friend and her cousin in there holiday home, due to the lack of rooms, during the night, her cousin and her friend started fucking on the floor about 2 feet away from my girfriend, they both thought she was sleeping as they were quiet, she she was watching with a cheeky, she told me her cousin, he was called mark, clocked her peeking over, but carried on fucking anyway, that turned her on and im guessing both of those. she never joined in but she tells me thatif she was to go back there now, she would join in with fucking her friends and cousin...
