Fuck I cheated! He used me and inseminated me.

What kind of stranger was that? And then without a rubber, but I had absolutely no idea what to do... It was Friday lunchtime and after work! I had everything ready and wanted to go home to my husband until suddenly my colleague was standing in front of me with a folder that I was supposed to work on until I suddenly saw that his cock was sticking out of his trousers... I was speechless and didn't know what to do... I didn't want to turn him away out of respect so I bent over the desk in shock and took his cock in my mouth. I thought that was enough but he came round to me and opened my bodysuit, pulled my briefs aside and when I asked for a rubber he put it in bare... absolute nogo but unfortunately I found it so horny and exciting and that he then squirts in and on my pussy and then pushes everything deep into me again really blew me away ... Is that normal or just taboo?
