Slept With A Married Actor

I work for a large live arts venue in London. Earlier this summer, we premiered a new show and I really hit it off with one of the actors in the company. He's not super famous or anything so you probably won't have heard of him unless you really know your theatre and TV in the UK. Anyway he's in his early thirties, tall and muscular with broad shoulders. Not to mention very charming. In short, I fancied the pants off him, and I could tell he was interested in me too. I soon found out he was married, so I didn't think anything was going to happen. Not that it would've stopped me, and at the opening night party, it turned out it wasn't going to stop him either. I met his wife for the first time. She was lovely. I spent a lot of the night chatting with her, trying not to let on that I had the biggest crush on her husband. When the free booze ran out at the bar, I went up to our offices to sneak a couple of bottles of wine for us so we could carry on drinking. He offered to come with me to "give me a hand." We were chatting and laughing as usual, but once we were alone in the office, now several drinks in, things took a turn. One second, we were looking into each other's eyes, the next, he'd grabbed my waist and pulled me into him. We made out passionately as his ran his hands all over me, and told me how sexy I was. I think he'd have fucked me there and then, but I reminded him that someone could walk in at any moment. We reluctantly broke apart and went back downstairs. I felt so naughty as I handed his wife a fresh glass of wine, knowing that her husband had just had his tongue down my throat. An hour or so later and things started to wind down. Some of the cast were going onto an after party but I could see that she was ready to head home. He said he was going to join them for a bit, but that he'd book an Uber for her. Smooth. As soon as she'd left, he discreetly put his hand on my arse and asked if I wanted to get out of there. Pretty soon we were bailing on the after party and heading back to my place on the tube. The sex was phenomenal. He was great in bed, and explored every inch of my body with his hands, mouth and tongue until I was soaking wet and ready for him to take me. I lost count of the amount of times I came in the two hours we spent ravishing each other. It was such a turn on, knowing that this hot, older married guy had lied to his wife, just so he could shag me. I was utterly spent and blissed out by the time he snuck off home. I don't think either of us felt particularly guilty. I know it was a bad thing to do, but it was also a lot of fun. Plus it was just a one-off and his wife has no idea, so as far as I'm concerned, there was no real harm done. If I've learnt anything in life, it's that when it comes to sex, humans just aren't wired for monogamy.
