We had joked about it for months, but two days before my 30th birthday, I got my wish - a threesome with my husband and his best friend, who happened to be my ex.

I'm 5ft 6, long dark hair, cute face and a curvy UK size 12-14, with 36f boobs. They have always been my stand out feature, by 15 I was a C cup and a DD at 18, which always got me attention.

It was when I was 17 that I first met Josh, and it was because of him that I met my now husband.

We had a little flirty few weeks together, but never went all the way. Kisses and touches, and a very quick handjob while he grabbed my boobs (through my top) was all we did together as kids.

He then went on to another girl, leaving me. I happened to get with one of his friends, Ben, a little while later after one or two other boyfriends in between.

There was always something there though. On nights out Josh would flirt wildly with me, in front of everyone. He squeezed my ass when he hugged me and would kiss my cheek really close to my lips. I felt myself tingle every time. There was unfinished business here that I never got to fully feel.

Ben and I had a great sex life. Neither of us could get enough, and we would have sex at least 4-5 times per week. He loved my big boobs, and that I was loud when he was inside me. I loved his big shoulders and would hold on to his back as he got deeper into me, always wrapping my legs around his ass to pull him closer as he came.

After years of fun though we both wanted to spice things up a little. I loved dirty talk during sex, and it drove him wild, and one night after a few drinks we somehow ended up talking about a threesome as we were stripping each other.

We both said we would like a girl or a boy to join us. I always liked girls, but apart from kissing friends and feeling boobs when drunk, I'd never done anything about it. And another guy, two dicks to play with, well this could be a lot of fun.

I kept up this chat whenever we fucked, it got Ben so horny to think of me being fucked by him and another guy, or for him to have his way with me and another girl.

He would struggle to last when I told him how much I wanted to play with two dicks and feel both inside me at the same time. On one occasion, after a couple of drinks, I even took out an 8 inch dildo from my bedside table while he fucked me and gagged myself with it. He came inside me in seconds, and I loved how naughty it felt.

We would joke about who we might pick. He never had the guts to say any of my girl friends by name, even though I caught him looking at some of their tits and ass when we've been out. For a man to join us well hmm let me think, Josh could be fun! He seemed okay with this when I said it one day, so I kept bringing it up to see how far we could go to make this a reality.

Josh would sometimes stay over, sleeping on our sofa. Since the threesome talk started, I was hornier than ever, especially around Josh. I would flirt back, and graze my bum against his groin as I passed him, oops by mistake.

I saw my chance to do even more when I found out he was staying over again - it was too early to have a threesome but could I get him going? Would he even want to back up all the flirting with action?

After a great night out, we headed back to ours for a final drink, then Ben and I said goodnight to Josh on the sofa.

Ben and I went upstairs and within seconds he was all over me, squeezing my big heavy tits, kissing me deep with his tongue and I could feel his raging hard-on through his jeans. He pulled my top down and took my bra off, eagerly sucking my nipples as his hands moved to grab my ass. I was wearing a skirt so he pulled that up and ripped my knickers down, almost breaking them in the process! He was so horny and I was so wet.

I went on to my knees with my top down, boobs out, and skirt up, and pulled his hard dick out. I began sucking him and could feel him become even harder in my mouth. He started to moan as he played with my tits.

He couldn't take any more, and neither could I, we jumped onto the bed and he bent me over, quickly sliding in to my wet pussy and began fucking me hard.

I could see my boobs swinging back and forth in the mirror opposite the bed which did look hot, I held one and sucked my own nipple (the joys of having big boobs) as I moaned and said loudly 'thats it baby, fuck me hard, make my big tits bounce. Yes baby get deep inside me'. I was a bit louder than normal on purpose - I wanted Josh to hear. Imagine him walking in to the room and just joining in! Mmm heaven.

There was no sign of Josh, and we both needed to cum, so I flipped on top of Ben and started riding him, grabbing my big tits and playing with my nipples as I grinded on him. He came within seconds and we were both so loud. I didn't cum, but I had a silent play once he went to sleep.

The next day I woke up to a text from Josh saying 'sounded like you guys had fun' - he had heard us! I replied pretending to be embarrassed, but he said he was glad we had fun. I said we did and I can't help being loud when I enjoy it. We left it there.

A few weeks later a friend of them both had a birthday party arranged - just the guys - all getting together in his house to drink and play cards. Josh asked if he could stay over, and I knew this was our chance. We exchanged some flirty chats in the days coming up to the birthday, and I was dirtier than ever when fucking Ben - he was up for it every time I mentioned Josh.
