20th Wedding Anniversay Affair!

Last year was my 20th wedding anniversary and we threw a party at our house to celebrate. My two teenage boys invited some of their friends, me and my husband invited our friends and family around and it was a great night! However I did end cheating on my husband. Our sex life was as good as dead and I was sexually frustrated, I accidentally spilt some wine down my dress and went upstairs to my bedroom to change, when I was half naked in just my bra and knickers my eldest son's friend, Jake walked in. He apologised for walking into the wrong room but was just staring at me. After a few seconds he closed the bedroom door and started coming on to me. I tried my best to resist it and walk away, but I couldn't do it for long. With in 10 minuets we were in my bed having the best sex I have ever had! He got on top and started fucking me really good and hard, while everyone including my husband was downstairs. When we finished, he put his number in my phone and told me to call him if I ever wanted sex like that again and I hate myself for it but since last august, I have been meeting him every week for at least one night of sex.
