We  were still a fairly new couple having only been dating for about 2 months when this experience happened and we were both really enjoying our new  found relationship, sex was amazing.  We live in a very beautiful place and I was very excited to start my new life and explore everything it had to offer, I'm a very adventurous and playful female ( T) and my excitable energy can be contagious at times. I started a new job at a lingerie shop and was enjoying the sexual energy of the women that were buying up the sexy outfits and loved the idea that I was helping them look super sexy for their partners.  The other girls that worked there were younger than myself and fun and full of inexperience, but very eager to learn and experiment. I became close with one girl in particular, her name was Beth.  She was very smart and sexy and playful and she always had sexual questions for me and I became a mentor towards her in a way. She was thrilled to get to know me more and wanted to hang out with my bf ( K ) and myself and really enjoyed our company. We invited her out on occasion to our place for the odd BBQ and we had kids around so we were very vanilla about it.  In my previous relationships before I met (K) I had played with mfm a lot and some mfmf and she loved hearing about my sexual experiences.  ( K) had not played in the lifestyle and we hadn't even had a chance to discuss it yet still being so new in the relationship.  I could tell that she was getting turned on when I spoke about ( K)  in a sexual way and she had mentioned how cute she found him.  (K) was really enjoying being able to make me squirt and I had told her that we were both loving this experience and how hot it was and how unbelievably good he was at it. Looking back I think this was a huge turn on for her and I believe that is huge part of why this experience became in the first place. Anyways she came over one night and watched a movie with us on the couch and her legs were towards me as she sat kinda sideways so her feet would touch my thigh.. her feet were getting closer to me and I felt like she wanted to test the waters, there was some touching and energy about it..it was getting late and we were starting to think about needing to get to bed soon.. keep in mind that she is much younger than us and we didn't want to assume that she was into anything more than just being friends and we didn't want to offend her and I didn't want to ruin our friendship. We started to suggest that it was getting late and calling it a night..she got up and grabbed her coat and slowly went to leave and conversation kept going and we were chatting and laughing and saying good bye and yes eventually she left... we closed the door and looked at each other with wide eyes and I said to (K) I dont think she wanted to go... and he agreed with me.. we laughed and bantered back and forth about what it would be like to have a threesome with her and joked about it being an interesting addition to our already amazing sex life.. soooo  Beth ended up getting a bf and he was much older than her like 15 yrs older and she had known him for a very long time and was super happy to be able to be with him in a sexual relationship, I now think that she had a thing for older men.. so some time goes by and she asks us if we want to join them for some drinks and we never turn down a fun time so off we go... Well we get to the pub and her BF is wanting me to sit next to Beth and starts buying (K) and I some drinks, which turn into more drinks and we are having a blast.. still not thinking that anything is going to happen at this point.. so it starts to get to be a bit late and they suggest that we all go back to our place for some more drinks.. (K) and I are into it so its a go.. they leave and head to our place, we leave and now that we are alone we can have "THAT" conversation.. (K) turns to me and says I think they are priming us for some fun, Im skeptical but kinda agreeing with him..keep in mind we are pretty drunk and feeling no pain.. and completely not prepared for what is about to happen and we don't even know at this point what that is if anything.. so we get back to our place and we are all in the kitchen and Beth is standing very close to me and says something about wanting to kiss me.. Im like did I hear that right, you want to kiss and she beams with anticipation. I take one look at the boys and grin and say lets do this!.. I dive right in and start kissing her, nothing like kissing another woman, its soft and wet and gentle and sexy as fuck.. I start feeling her breasts and running my hands all over her body letting them explore every beautiful curve and start getting right into it.. she is loving it moaning and feeling me with her innocent hands.. dont get me wrong I loved being like that with a woman, but I do appreciate the male body and their sexiness, so I look over at the men and they are stroking themselves with these HUGE smiles on their faces..( after the fact ( K) was like OMFG that was so hot to watch you with another woman YUMM... ) so I want to change things up a bit and suggest that we all head into the bedroom thinking we are going to have some fun with our men.. I suggest we kneel while the men sit and we suck off our own men first.. of course the men are all for it.. so like 2 min into sucking away Beth looks at me and says "switch? " before I can say anything she is on ( K) and I grin and look up at (K) and he is modestly grinning when he realizes she really wants to suck him.. her bf is not overly thrilled about this and starts to show signs of not wanting to share Beth in this way.. so I catch on and we stop sucking and (K) excuses himself to go to the bathroom, leaving us three alone.. I suggest that I show Beth's bf how to make her squirt and she beams with delight and lies down in preparation for the climax, he attempts to play with her pussy and really has no idea what he is doing.. so I politely make a few suggestions and he starts working his fingers and she is groaning and loving the play, but no squirting is happening.. (K) walks in and says what do we have here, I fill him in on the squirting attempt and the bf says I can't seem to make her squirt.. right away i'm like would you like (k) to show you how?  The bf stands up and says yeah Please... (K) starts to work over her bright pink tight little pussy and inserts his fingers into her already wet pussy and goes to town with his magical up and down motion that drives me crazy!! She EXPLODES all over his arm all the way up his arm like waterworks!! The bf is wide eyed and smiling with amazement.  Beth is quivering with excitement and pleasure... (K) is laughing with accomplishment and ooozing confidence.. which turns me on so much.. we decide to stop and clean up a bit and realize it's late like super late and  we need to call it a night.  They gather themselves and head out while we take one look at each other with these huge grins  on our faces and disbelief over what just happened.. The next morning beth messages me and says that before they left her bf mounted her onto the roof of their car and went to town on her pussy making her squirt again in our driveway.. wow this was so hot!!  (K) and I then realized that Beth was a very horny girl and would have played with us when she was single and might have had a crush on (K), but we missed out.  Dont get me wrong we loved the whole experience it was so hot and we still joke about Beth to this Day!!   We didn't get another chance and her BF seemed to catch on that she had a crush on (K) and we don't think he liked that.. Hence the UNICORN that got away... its been 10 years since.. oh the memories.. lol :)
