After our boundary pushing vacation in Phuket was over, we soon slipped back into our normal working routine and social life.
Meeting friends for dinner the first weekend post holiday, I couldn't help but WhatsApp Mei while we were at dinner, teasing her that our friends would be shocked to know what had happened on vacation.
The subtle smirk, coupled with her best attempts to ignore me, suggested I had hit the right note.
The passionate making out and fucking in the car park before driving home was the icing on the cake, as we both enjoyed the memories fresh in our minds.
Clearly the events with Steve and Sarah had lit a spark, and that fire was still burning.
A few months had passed when I received an email from Sarah, which was a pleasant surprise.
Sarah had something she would like to discuss, so I replied with a convenient time to call, and looked forward to hearing from her.
I would be lying if I said I wasn't intrigued by what Sarah may have in mind, her creativity and lust was matched by her open, direct nature.
That evening while chilling out after dinner, my mobile starting to buzz.
Putting the phone on speaker, Mei joined me as we greeted Sarah, and after the usual small talk pleasantries, Sarah took us both by surprise.
Sarah's proposal was for a couple swap, that is, Mei to visit Steve, and Sarah to come and stay with me, for a weekend.
I looked at Mei, and we agreed to discuss it, and call Sarah back.
Ending the call Sarah mentioned she was looking forward to our reply.
We both sat in silence for a few moments.
While we had actively experienced sex with other people, the recent experience with Mei visiting Steve and Sarah's apartment, without me, had pushed our boundaries and an entire weekend would take things well beyond that.
I broke the silence by asking Mei what she thought.
While the idea excited her she was nervous to be away from me, in case something happened, though she admitted it could be a wild adventure.
Patting my knee for her to take a seat, I placed my hands on her thighs as she straddled me.
A deep passionate kiss followed, and running my thumb over the front of her panties, I was not surprised to find Mei's pussy was nice and wet.
Clearly she was very turned on by the idea.
Pushing her panties to the side, as I unzipped my pants, My rigid cock was inside my beautiful girlfriend within moments.
Her moist welcoming pussy taking all seven inches at once.
Being inside Mei as she started to work her hips on my cock, I was delighting in the pure pleasure and lust that so often occured between us.
We stopped kissing just long enough for me to ask Mei if she would like to go ahead with Sarah's suggestion.
Her instant moan and increase in intensity as she rode my cock with aggression, suggested she wanted to.
Resting her forehead against mine, she replied that we should try, though she was nervous as to what Steve might arrange.
I told her that she would be free to do what she wanted to, as long as she gave me the full details once she returned.
This seemed to push Mei over the edge as her pussy started contracting firmly around my cock, her body gripped by a powerful orgasm.
Moments later I pumped my load into Mei.
Not able to take any more, yet delighted from the impromptu fuck.
As Mei climbed off me, I couldn't help but admire her gorgeous petite body, and smiling to myself, knew that the upcoming experience would be pushing our relationship to new territory.
The next day I phoned Sarah, and let her know we were willing to try out the partner swap.
We discussed a few dates and found a weekend a month away, where everyone could travel and be available.
I set about arranging Mei's flight to Phuket, and forwarded the flight details to Sarah. Sarah replied with her flight details and I confirmed I would pick her up in a few weeks time.
The time till our weekend flew by, literally. With work trips taking up the bulk of the time, Mei and I had hardly discussed what we expected to happen, or our thoughts about the planned adventure.
Two days before the adventure was to begin, Sarah called and sounded quite upset.
Her mother had passed away suddenly, and she was flying back to Italy that afternoon.
We expressed our condolences and assumed that our plans would wait till she returned.
To our surprise, Sarah asked if Mei would still be traveling to Phuket, for the weekend.
Sarah was fine for Mei to still visit, though she highlighted Steve had some friends in town as well, so he would be able to fill his time if she decided not to go.
I thanked her for the call, and said we would call back soon, once we had discussed the situation.
Mei was hesitant about going, without Sarah visiting me. I agreed it wasn't the original plan, though pointed out that with Steve having friends in town, she might be able to enjoy some alone time at the beach.
This seemed to spark more concern in Mei, when she highlighted Steve's friends might expect something from her, which was too much for her to consider.
After some time Mei agreed to still go, though she did have some concerns.
Returning Sarah's call, I informed her to let Steve know to pick Mei up at the agreed time, and for her to have a safe trip home.
As I disconnected the call, my mind was full of mixed emotions.
Incredibly turned on by the possibilities, I was also aware that given Steve's character, Mei could be in for an intense weekend.
Keeping my thoughts to myself I reassured Mei that I loved her, and that she should make sure that she packed her sexy lingerie and outfits, as well as her bikini, just in case she had some time to herself at the beach.
In no time at all I was driving Mei to the airport and checking her out as she sat there. Clearly nervous but also excited, her denim mini skirt the perfect outfit to highlight her slender long legs, while her tight baby t shirt revealed her flat toned stomach and teased at the sizeable breasts as well.
I smiled knowing that Steve would love what he saw.
Dropping Mei off, I asked her to whatsapp me once she was there, and to whatsapp me if there was any need to.
Besides that, we agreed to maintain 'radio silence' and I would pick her up in two days time, where I expected her to fill me in on every detail.
A quick smile, followed by her repeating that she was really nervous, and she was off through the terminal door.
Her beautiful ass catching the attention of a few men as she walked in.
The drive home was a blur. My mind was racing with the possibilities and I admit, I was super turned on by what was happening.
Reaching home I settled in for a relaxing afternoon, before meeting friends for dinner.
