It was not my first experience of threesomes, I had previous MMF and MFM with my ex, but for my new girlfriend it was, and it was to be her first Bi experience too!. I had met Caroline, as I said, once before with an ex, about a year and a half ago, that "meeting" was better for me than my ex, though she said she had enjoyed it. I received a text from Caroline asking if I would like to visit again, explaining that I was no longer with my ex I said I would talk to my new girlfriend and ask if she might be interested. For those that have never asked a quite new girlfriend if she would like a Bi experience, and part of a threesome too is not an easy thing to bring up!, however I was surprised when she said she had in fact always thought about it but had never tried or had the chance to try it before. I thought we might as well go for it rather than give her time to think so I text back would tonight be possible?, the answer was a yes, no time for nerves to take over. Caroline lived around 50 miles from us but we arrived at eight as planned with Caroline opening the door in a very short skirt, fishnets, and a small top just covering her, I would say, 38G boobs. Oh she said to Sam my girlfriend, I thought you might have dressed up?, Sam looked very smart but quite formal in dress, it didn't matter though. Both being bubbly kind of girls they soon got chatting, helped by the wine we took with us, both have the same kind of personalities and I just sat listening and wondering how and where it was all going to start. Caroline left the room for the loo, I looked at Sam, looking for signs of worry or fear!, what do you think so far?, oh she is really nice, I was a little shocked at what she isn't wearing. Caroline returned and said lets go to the bedroom, a prompt we both needed to move things along, Sam removed her clothes and was left in just a nightie, I should point out that both Caroline and Sam are what you might term BBW's. Well that can come off for a start, said Caroline, pulling at Sam's nightie, I was surprised and so was Sam, but really it was what was needed, Caroline taking control, being Sam's first experience it was the right thing to do. So I sat naked on the edge of the bed watching, I have to say at this point that I knew my part in this, I knew that I could join in, and did, but this was for the girls and anything I got was a bonus for me not them!. My "reward" was instant, to see my new girlfriend have her first experience as they kissed softly, tongues flicking was just amazing, their hands caressing ample boobs and hardening nipples, I was more than happy at that stage just watching. Caroline really took control, knowing what she wanted, though not having all that much experience either she led the way for both of us, kissing down Sam's body, sucking on her nipples, she worked her way down her body until over her already wet pussy. As Sam has since said what happened next, for her, was the most amazing thing, Caroline gently pushed back Sam's legs opening them as she did so exposing her smooth and clearly wet pussy, mmmmmmmmm look at that John, she said to me, look at me opening you're girlfriends pussy, with that she lowered herself and began to lick along Sam's lips and round her clit. I looked up at Sam, I didn't need to, for the sounds she was making gave me no doubt how much she was enjoying it, deep moans that I would have been pleased to have heard had I been doing the same. Caroline was on all fours, I moved round to the foot of the bed and ran my hands over the cheeks of her bum, watching and enjoying all I could see, I gently rubbed on her clit and entered a couple of fingers while I watched. They changed positions and now Caroline was laying exposed to my girlfriend, I watched as she opened her lips, took the first lick round her clit and then after a while doing that really got into it and begun to tongue fuck her, I thought the time was right to move things along so I moved alongside Caroline and held my cock next to her face, even then I didn't know if that was the thing to do. Caroline took my cock in her mouth and began to suck, I was looking down at Sam still enjoying her first pussy, look sweetheart, I said, Sam looked up to see Caroline sucking away on my cock, my girlfriend licking another woman while watching her man be sucked, seemed unreal. Sam moved up and knelt the other side, reaching forward she took hold of my cock and began wanking it into Carolines mouth, we kissed as they had kissed and both leaned forward and took a nipple each and sucked. This story could go on, we was playing for over three hours, including times with strap on's and dildo's, It was a fantastic time for us all, but for Sam, being her first time, she was amazed and wanted more. Some people write fantasy, others simply dont believe, the fact that after all the above and more I didn't even cum, I knew why I was there, I knew it was for them, believe me I didn't feel and was not made to feel left out, at the end they were both satisfied, as I was to be when Sam and I got home, we are talking about meeting another couple now,never tried swapping but we both would enjoy it I am sure, but just got another text from Caroline, would we like to visit again?, this time I am going home satisfied too! .
