Thank you for all your constructive comments, they are most appreciated.
If you have not read the first chapter (Part 1), I recommend you do as this I hope sets the scene, and provides a foundation for what's to 'cum'. lol
As I've said before Steve would regularly ask, suggest, encourage us to expand our sex life, with me and another guy generally top of his wish list. His cock always overruling his head, but there were many other wider issues, the question of what effect having another guy involved would have on our marriage, of course I, we didn't know, but for me that REALLY was a BIG concern.
Looking back, was it inevitable I would have sex with another guy, mmmm a good question, I suppose over a long, long period of time, you could say Steve wore me down. Although it wasn't as if my 'first' was a stranger, indeed far from it. Some years previous we (Phil and I) had almost 'got it together' whilst on holiday. Strange that during that holiday with his wife, Phil and I got quite close (but not close enough), being much more 'touchy feely', although careful not to give his wife cause for concern. Strange really that it took us, me so long to actually 'do the deed', inspite of increased pressure from Steve, seeing what went on between Phil and I on that holiday. We never really found the right time, even with Steve working hard to facilitate our 'coupling'.
Phil was, is Steve's best friend (and Best Man at our wedding), but fast forward a few years and he was going through a messy divorce, Steve and Phil regularly going down the pub for a few pints to 'drown his (Phil's) sorrows'. I could not help feeling sorry for him, the way his wife was supposedly treating him, the drinking developed to a weekend, Saturday night 'bender', and I would go along sometimes if I wasn't cooking a meal, not sure if it was inevitable, or it just happened but Phil ended up staying overnight occasionally which wasn't a problem, this was in our pre-children days.
Steve thought I was not aware of his motives, but he is so predictable (aren't all men), his cock encouraging him, to persuade me to give Phil a cuddle etc. seeing a good opportunity for me to at last get together with Phil. Later, a LONG time after I found out that he (Steve) had chatted quietly with P, making suggestions, confirming he had his full blessing to fuck me (what a cheek). Of course, Phil knowing this, started making more and bolder 'advances' in my direction, more compliments, gifts as a 'thank you' for allowing him to stay etc. Yes, flattery and pressies I love, but I was somewhat not so much embarrassed, more mad, angry, with a tinge of humiliation when P bought me some 'sexy', silk lingerie for my birthday. S adding insult to injury by suggesting I should model them so they could see if they were right size/fit, yeah right! I do admit, that the devil in me wanted to show Phil, flaunt myself in front of Steve, just see the look on Steve's face, but no, pride and respectability overrides any lecherous male chauvinist ideas.
OK, now brace yourself here (lol), a few weeks later, possibly because I was feeling horny, not to say mischievous, a few glasses of wine to many probably helped, it was time to show the boys that yes the lingerie items fitted perfectly. Yes, yes I know what logic, why, how did I come to this stupid decision, I cannot answer those questions, may be I was bored, needed a bit of 'fun', things were getting a little mundane, Phil and Steve down the pub, wifey dutifully at home in kitchen cooking, perhaps also I was feeling a little rebellious, whatever?
I remember at the time, having showered, pampered myself, it felt good with fresh new, silk underwear always has that certain effect on me, taking extra care to ensure my boobs sat nicely and comfortably in the underwired padded bra, admiring myself in the mirror, my cleavage never looked better (even if I do say so myself!). Sauntering into the lounge covered by my old dressing gown, which I suppose did not really do justice to my fine lingerie was beneath. I didn't hear a loud noise, but I'm sure both S &Ps jaws must have bounced off the floor, as I sat down, I did try 'lady like', but I knew full well the dressing gown was not long enough for that especially as I deliberately crossed my legs revealing a large amount of thigh, the waist tie also 'bowed' open under pressure from my bra loaded boobs. I was feeling hornier by the second. We talk of milestones, and this was certainly one for me to remember, the first time I felt that it was me, I had the power over men, not Steve having power over me, don't get me wrong he's not like that, I just felt more 'empowered'. Looking back, perhaps it was because I wanted to be in control / charge rather than a subservient female doing wishes of her superior male masters!
There was not much if any conversation, a stunned silence I suppose, looking over I could see the boys had beers, Steve taking the hint asked if I wanted a drink, but of course I do, he went to get me (another) wine, freeing up the sofa seat next to Phil. Was I going 'in for the kill', not sure, but I got up, my gown tie starting to naturally get loose, I shouted through to S asking him to check on the cooking, I was pleased with myself, on the spur of the moment, buying myself more time alone with Phil.
