So this is part 2 of my "Friends First" story, which, if you have not read part 1, was about the transition from friends to lovers between my co-worker Mags and me. With absolutely no sexual prowess on my part whatsoever, I stumbled into a situation where I was to become the "M" in a "FFM" love triangle.
Mags and Mary had been lovers for several years. It was not an open relationship, but they had fantasized about adding a man to the mix, but only if they could find someone who would be respectful and trustworthy.
Mags held Mary's hand as she introduced Mary to me as her significant other, I was pretty sure that our physical friendship was coming to an end. Sensing my anguish Mags approached and took my hand in her free hand and kissed me hard on the mouth, and then did the same to Mary. I sure that the "what the fuck" look on my face perfectly betrayed the confusion in my head. Then Mags sort of pulled Mary and me into an intimate little circle, Mary kissed my cheek and whispered "welcome to the family Dan".
Mary was a 40-something mother of two independent young adult kids, the birthing of which left hardly any evidence on her well-toned little body. Where Mags is rather tall, Mary is a more typical 5'4", maybe 125 pounds, smallish hips and waist line, and boobs that overstuffed her C-cup bra.
I seriously do not remember whatever thoughts were in my head when Mary turned to Mags and initiated what had to be the sexiest French kiss I've ever seen. I also don't know what Mags had cooked for dinner that night because we never got around to eating... dinner. It also turned out that this was the first MΓ©nage Γ Trois for any of us, so we were probably beginning our session rather clumsily. It wasn't long before buttons were coming undone; first the girls did each other's blouse, then Mary started on my shirt while Mags went for my trousers. I had got in the habit of going commando on the nights I spent at Mags house, and the sight of my hard dick popping right out as Mags pulled my pants down caught Mary a bit off-guard. She laughed and said "it's been a few years since I've used one of these" as she sunk to her knees and began playing with me. One hand went right to my cock, while the other went between my legs to my balls and butt cheeks; I wondered if all bisexual girls were as skilled with their hands as these two. Mags asked me if I thought two girls were going to be twice as much fun and all I could think to do was to kiss her.
One of the girls suggested we move it to the bedroom, and as we did, all of our remaining clothing hit the floor. Mary landed in between us and I could tell by the way she and Mags looked at and touched each other that their bond was the real deal; I had been having deeper feeling for Mags for some time now, and wondered exactly where I was going to fit in here.
