"A couple of years ago, I started talking to a coworker. The conversations got longer and longer, and we flirted constantly.
A couple of months went by, and it was my birthday. She texted me, saying she had a "special surprise" for me. I had no idea what I was getting.
On my birthday, she met me after work. Then she started undressing us both, kissing my neck and telling me extremely naughty things about what she wanted to do with me. I was still a virgin, so it thrilled me even more.
And then, as she pushed me into the bed with a quiet "Grr", she grabbed my cock and slid it into her tight hole, before riding it slowly, quickly picking up the pace. We moaned, kissed and fucked each other for who knows how long, until she let me cum on her boobs with the greatest pleasure. As she took a sample of the cum and tasted it, she whispered in my ear with a naughty tone "Happy birthday.""
I read recently that over 30% of affairs are with coworkers, and 80% of single people want to hook up with someone at their company ... and that is certainly reflected in many of the xconfessions here! But what I liked about your story was that you lost your virginity on your birthday. Who needs cake when you get a present like that from your not-so-secret admirer?
