The following morning M apologised for her reaction to me the night before explaining that her head was 'all over the place'. She had enjoyed her evening with Phil. The excitement and adventure of being with another man was awesome for her but she still couldn't fully reconcile the fact that firstly I was ok with it believing I must have some ulterior motive. That 'marriage thing' was bothering her as well. Without boring you we had what I believe is an age old conversation between men and women that sex is a pleasure thing not a measure of love and that as she was not deceiving me and I got pleasure from her exploits then there was no betrayal. But her worst fear was what if someone we knew found out. Unlikely I explained adding that it was our business so who cares what anyone else would think. M wanted to carry on having fun with Phil despite her confusion. I wanted it too. Over the next few months M had three more evenings out with Phil. Each time on her return she would tell me in detail what had happened as we had sex. During these months I noted that her choice of dress changed. She had had a day of shopping for herself and I could not believe what she had bought. Six inch heeled shoes, skirts that only just reached her mid thigh and underwear that was far sexier than anything she had worn before. The stockings were the very sheer, seemed, lace topped type that previously M rejected purely on the cost basis. The first time she wore this stuff I was shocked and amazed in equal measure. The skirt was so high that no matter how she tried to sit a flash of bare flesh and those stocking tops were revealed. I joked that if anyone dropped a fiver she better be careful how she picked it up. The extra 2" of heel also transformed her from having nice legs to legs you couldn't take your eyes off. After her first night out wearing this attire she described how every man in the pub had stared at her and how obvious it was that men were discussing her. This excited her which was only increased as Phil encourage her to deliberately flash one or two. He had even undone a further button on her blouse, which was more than obvious to some, whilst sat at their table. This had revealed her lacy bra and cleavage more and had even received a silent round of applause from one chap sat on the other side of the pub. The sex with Phil and I that night was incredible and the best she had ever had she said after. It was a Thursday evening. I knew M was out with Phil and as it was reaching 11 o'clock I was expecting her home at any moment. At 1am I was really worried. By 2 I was at the point of distraction. She had never been this late. I had tried her mobile phone several times but there was no answer. Eventually about 3.30am, despite arguing with myself not to, I rang Phil. I introduced myself. 'Do you know where M is?' I asked. 'Not seen her since she left work' was his reply. I asked again. Same response. Such was my concern I thought 'sod it' and told him I knew she was him. Initially he denied it but I blurted it all out that I had known all along and encouraged it. I even told him he should thank me for allowing him to have my wife to reinforce I knew and was accepting of it and not about to hunt him down for revenge. After again relaying my true concerns for M's safety he finally relented and admitted M was with him. 'She's had a bit too much to drink but she's fine'. As he spoke I began to hear other voices growing in the background. 'Where are you?'. 'Friend's house. Having a party' Phil responded. I could now clearly hear cheering and laughing in the back ground. I could also tell by his voice that phil was a little drunk. 'Do you want a word with her?' he asked. I was about to reply when Phil added 'you'll have to wait though she's got her mouth full'. My immediate thought was that she was sucking Phil off, but M didn't like to do that, or at least I struggled to get her to do it. Despite thinking this I stupidly said 'late night kebab?' Phil's response was literally mind blowing. 'No. Right now it's cock'. The phone muffled slightly and I heard Phil ask someone what someone else's name was. He then spoke to me and in a slightly slurred voice said 'to be precise it's Mitch's cock'. I couldn't say anything for a moment, then asked 'who's Mitch?'. 'Gerry's mate. Gerry right now is fucking her arse'. Shocked. Memorised. Confused. What was going on? 'Can I speak to her, please' I said please. Why?. She's my wife and from what had just been described please should have been the last thing I said. 'It's your hubby' I heard Phil say. 'Hello'. It was M. 'What the fucking hell's going on?' I was angry, partly that M was so late home but also that I had an image in my mind of what was happening together with thoughts that M had been untruthful in that she hadn't told me that there were other men. Ridiculous I know, given the circumstances that it was I who had encouraged her on this path. 'We're having a party' she said. 'More like a gangbang' I retorted. 'Ok, maybe a little one. You don't mind do you? With that I heard several men's voices shout in unison 'we don't'. M started to giggle. The phone went muffled for a moment then a man's voice I did't recognise said 'do you mind old chap' in a put on toff's voice, 'but my friend's and I are trying to give your wife a good old seeing to. So if you don't mind'. With that the phone went dead. Christ. What the hell was going on?. I would find out later that day.
