I've Been Unfaithful...and I'm Addicted

I was at work. I work in a school, and as usual at this time of year, most of the classes were working on their Christmas preparations so I found that I was not needed as much as I am usually. Instead of teaching, I had a whole afternoon off so I decided to attack one of the rooms that we keep music resources in. It's become something of a mess so it really needed sorting out. I was wearing a skirt, usually I wear trousers to work and was standing on a chair reaching up for a box when the caretaker popped his head round the door. He often is quite flirty with all the female staff so when he said, 'Blimey Ruth. Your wearing a skirt. Careful you don't show your knickers' it wasn't a surprise as he is quite cheeky as I said. However, I replied 'What? Like this?' and just lifted my skirt! I was amazed at my own brazenness as I am most certainly not like this. Under my skirt I had on what I can only describe as the most boring panties in the world. Just little white cotton bikinis. Sorry if you were hoping for a silk thong. He stared at me and whistled appreciatively. 'You know, Ruth' he said 'I can almost see your pussy lips.' Again, and by now with my heart thumping away in my chest, I reached down and just tugged the material to one side. John walked into the room and closed the door behind him. The next thing I knew he was standing in front of me as I stood there, skirt round my waist and knickers pulled aside, and fingering me madly as his tongue found my clit. He reached between my legs with his other hand and pushed a wet finger deep in my ass. Soon I was in the middle of a huge orgasm. I came down off my chair, and my cum, and unzipped him and got his cock out and started to jack him off. I asked him to tell me when he was going to cum and as he did, I pulled the waistband of my panties down so he came all over the crotch of my panties and my pussy lips. When I got home that evening, I grabbed my husband in the kitchen and pushed his hand in my panties and told him exactly what I had done. He asked me if we had fucked, but of course, I said no. He looked disappointed a little when I told him that the caretaker hadn't cum inside me, but the next second, I was bent over the kitchen table being fingered from behind to another glorious orgasm. It ended with a really animal-like shagging from behind. Since then, we agreed that I would go all the way if I got the chance. My husband also returned the favour too. He told me of a girl at work who he fancies and he has been lending her CDs and things, and, at my suggestion, flirting with her. Last week, he came home from work very excited and told me that she had asked him if she could do anything for him. They had ended up in a toilet in the office with his fingers in her. When she had cum, apparently she had squirted into his hand and he rubbed it into his cock. When I got my hands on him, he smelt of pussy and I sucked him off. It was my first taste of another girl. Well, as he is watching me write this and we are both highly aroused, I think that the best thing to do is, go to work.
