I Live in Bangkok with my Thai tgirl partner , for the last 8 years. Great life, happiest I've ever been, sex that's just been mind blowing at times. I am truly blessed and a lucky guy.

My partner , who like a lot of t-girls, (especially Thai's) loves adding extra people to our sex life, but always guys. No other t girls (unless swapping their boy friends and usually in different rooms ) and never females.

Had recent bet , which I lost like I usually do. 3 forfeits , which she would choose . Put out some posts on here and had a few replies, few days all 3 picked.

There was one huge surprise though, one if the suggestions was getting pegged by a strap-on female In a 3 sum with either partner or bi couple . Saw it , added to her list of options, didn't think anything about it as , highly unlikely. Although when we talked about bi couples years ago , she did say the boyfriend who have to be so amazingly hot to even consider and no contact between here and female. Plus would have to get on with the female or know her as a friend.

I'd forgotten that highly unlikely conditional situation. She told me she had her 3 choices and there on one if the choices was that , bi strap-on couple. Highly confused, but not complaining asked ok what's the deal , what gives haha.

Told me about a female friend of hers , who I know and have always got on with ,but didnt know about her love of the strap on.they had on cocktail fueled nights out discussed the usual sex life stuff.my partner saying she was really happy to find a guy who was open minded and versatile,also easily persuaded and easy to trick into losing forfeit bets.

Talked about the bi couple and us in 4 sum,her friend had said she would love to use her strap on collection on a British guy,like myself and would see if she could find a guy so hot to my partner's taste that she just couldn't say no!

Was a few years ago and not really something they talked about much since other than joke teasing etc.

My partner continued saying that her friend had a new boyfriend of a few months ,and did i remember her telling me about it and how happy she was with him, before going out for nightout with friends including them .

My partner has know this woman for 15 years met through there work (partner in fashion her friend is a photographer) and both have done well In there careers , both running their own business's. Would say she is in my partners top 5 friends inner circle.which I realised when me and my partner first got together and got full on interrogation from this petite cute but total fireball for over an hour after way to many cocktails

Anyway I had met her new bf,got on well he is swiss German ,and living in Holland currently for his work.

My partner continued saying that she thought he was unbelievably hot and ,he is I had to agree .plus he really nice guy open minded and I was I remember at the time happy she had finally met a guy that she deserved and made her happy. Her new bf had a 3 question mini interview , no interrogation. And her gave her a you better look after this one speech haha.

Then my partner reminded me of our bi couple maybe guidelines. Me saying but they not bi! And her friend no way into pegging surely. Partner laughing said what after 8 years u didn't realise that about her, the way she dressed at times , previous guys she had come in and out if her life. They had discussed already and decided that casual meet to see how we got on ,and as we were Thick as thieves by the end of the night ,decided to work out a way to make it happen.

My partner saying he is the kind of cute hot she really wanted to fuck ,and her friend had said his ass was so hot and tight ,she had actually agreed to the bi swap! And was I ok with her friend,which she already knew I liked as a person and knew I thought she was cute .and now knowing about her kinks really hot and yeah ok if it makes you happy baby I will!!

Showed me a few pics of her in full strap on mode,and some of her bf which my partner really liked,and if course had sent some to her ,a lot of me and my ass in action.

So anyway as I'm as usual writing way way to much haha.on Saturday partner told me they coming over tonight and they wanted to start watching me and her bf in the what seems the favourite opener for my partner and now her friend,if watching me and the guy mutual cock play to porn ,which was a bizarre mix so everyone happy haha.

Had a text from her bf a few hours before,saying he just found out ,and was happy first bi experience with a guy was with me and then my partner.hoped i was cool with him.replied about the whole bi couple conditions and rules my partner had said,so yeah all good .he was a bit surprised my partner thought that about him.your hot and partner wants your ass.he told me his gf had wanted to peg my ass for years but my partner,as they friends just kept teasing her about it.

I won't go full crazy sex story or we will be here for days( unless you want me to later). They arrived early 7pm ,was kinda weird as I have know her for years but first time it felt a little strange,but not in bad way.me and her bf though had gotten a good friendship vibe already going and both found it horny and funny that our 2 partners had got something that had been brewing for years to happen.

Me and the guy sat on the sofa ,flicking through porn options ,the other 2 disappeared into bedroom to get ready ,which didn't take very long for a change ,both coming out looking really hot my partner in some sexy basque and stockings set with heels ,she in thigh boots panties and bra . cliqued looks but still horny classics ,took the tv remote of us, told us to strip to underwear , they picked porn and we just started some gentle cock stroking , naked very quickly, they deciding to direct what they wanted to see, which mutual stroking , both of us sucking , and wanted to watch us both cum whilst stroking each other . I had done this mutual fun for partners viewing before , but not for partner and her female friend.her bf first time really for anything like this , and was very chilled and honestly easy , probably most relaxed mutual wank and cum I'd had.he was cute as hell ,i could see why my partner had said yes ,as in the fantasy sex guy type ,he was as perfect as she could ever find.plus we got on well , enjoyed each others cocks,he was smooth 7 inch cock ,i do love smooth.

Realised as I was thinking all this and looking at his gf still in disbelief,he had noticed how hard I had got plus the throbbing and decided to go for it and get me to cum first,his pace faster grip a little harder,me playing catch up ,few minutes later felt myself fall back into the sofa as i exploded cum shooting high and far haha.he kept jerking until I was empty , then stood up in front of me jerking fast and quickly came over me .which his gf had told him to do if he could get me to cum first.my partner was so hard and looked so ready for this guy .

His gf came over took my hand and said come on then our turn now!led me into one of our bedrooms ,pushing me onto my back on the bed, getting on top of me in 69 position saying we going to stay like this , oral pleasure mode until I had recovered and was hard again(had taken some Cialis earlier and told her bf to do the same !!)

It was one of those rare moments when I remembered what a sweet pussy was like ,and she was small petite with one of those beautiful smooth pussys that as she pushed it onto my face I thought I might actually cum right away haha. Between her pussy and her sucking me it was 10 - 15 minutes and was ready and rock hard.

Could hear my partner through the walls,what sounded like she was face fucking him,his gf also noticed and listened for a minute or 2 at the action next door.when she had slid on her strapons harness and showed me 2 options in dildos and to pick one ,I just thought puck the biggest which wasn't huge 7 inch ish med thick, she noticed me looking at it saying this just warm up one and kicked open a box next to get feet with a very varied selection, my partner had used a 10 inch very thick dildo on me in the past and there were some in that box that were clearly a lot , lot bigger, which I knew I'd never be able to take. She did say I don't expect you to take them all but who knows haha, but did pull out one that was bigger than my partners biggest one , got to use something a little bigger , for bragging rights haha. Gently bent me over the bed felt her fingers lube my ass , sliding them in , before putting the first strap on against my hole , gentle pressure, leaning over me . In my ear could hear her saying ,U ready ,or no not yet ,for what seemed like forever ,before she lent in close and said ok followed by her pushing them strap on all the way one motion ,until i felt the balls on mine.she was happy, saying might get further into the box than she thought as she pulled out and started fucking my ass building up speed fast ,until pounding my ass hard for maybe 5 mins max,too easy time to go up a size or 2 .she contiuned to fuck me sometimes slow almost gentle ,before changing to hard fast pounding.increassing the length and the more challenging thickness as often as she thought she could .got to one that roughly same as my partner's one but definitely thicker ,then it became a lot more real.i felt the huge mushroom head sliding and rubbing against my now pretty open ass ,well so i thought,until she tried to to put in just the tip,which was for the first type slightly painfully ,felt my ass stretching way past its maximum before.she sensed my struggle ,poured some lube in to ass and her dildo head.abd went back to pushing the top ,which i never thought would go in ,she arched her back lifting the dildo angle up ,pushed my back and head down and push in the big head ,abd once in just continued,this time me making some loud moans and shouts ,asking for her to please stop.but just pulled back ,to give me some false hope before sliding back in ,and fucking me as hard as she could , rubbing her thumb against the dildo and top of my hole , could hear next door that they had also changed into him getting fucked by my partner , and my partner and his gf having a quick, loud conversation through the wall both laughing and he pushing deep after every part of the little chat.

My partner appeared surprisingly at the door , half opening it looking at size she was using took a quick few pics , before handing her the next size up and showing her a small close up video of her bf ass taking real cock for first time and the huge moans me still face down feeling a new tip pushing against my ass , luckily not feeling as big of a mushroom head this time , they both chatting and showing each other clips and pics on their phones I hadn't realized that she had even taken and my partner now holding onto part of the new strap-on pushing the head straight in , before they finished there mid break show and tell with what I found out later was our cum shots from earlier. Before my partner slapped my ass cheeks saying good luck and walked off with a dirty little laugh as I realised why , yes the head was smaller but the further the new dildo went in the thicker it got , about half way was already same thickness as the last one. She said this isn't the one I showed u earlier it's the size up , as she continued to push it further into my ass , they had left the doors open so could hear my partner fucking her bf hard him moaning , just about coping me in almost silence, my ass feeling it might just explode any minute haha. Then luckily the moment when my ass just gets past the point of now longer caring or resisting and became easier , slightly as she decided it was time to fuck me sliding all the way out and then balls deep in a slower rhythm than before , the thickness really stretching me past the half way point and then the pull out when it was ok until the return slide in , my ass just being slowly worked and getting destroyed , she flipped me onto my back so I could see the dildo , it looked huge,she strokef my cock and started building up speed again ,me thinking god don't pound like before! She said I'm going to fuck you until you cum .which after first cum always takes a while even longer with huge strapons in my ass.she built up to a semi pounding speed,my cock hard and wanting to cum but she made sure I didnt cum fast I could hear my partner's cum shot groan ,which made her pound harder and stroke me faster until that amazing feeling of just before you cum ,thinking hell yes haha.shot my load hard felt it tighten my balls as i came over me and her breasts and stomach. Amazing relief until I realised,she was no longer fucking me and her strap on was balls deep inside me, and for those who know that feeling of now I got to feel that thick 12 monster be pulled out of my ass , and if course she was slow doing that ,and that finale of as the head pops out and you lie there ass throbbing.unable to move ,as she came to my face,gave me a gentle kiss,and went off into one of the bathrooms. Me lying there totally fucked unable to move it think . Dazed ,confused and covered in cum .
