It was past 4 PM on a Sunday as I am just waiting to go home. Two people are left in the office, me and one of my older colleagues that arrived late at work. My work was done while she still had work to do but I was bored. I thought to myself, it is now or never to get some action with my colleague since we are alone and she has seen my dick before, only because of a photo that she asked for after finding out about the sex between me and one of our other colleagues. I won't be having any sex with her though, instead, maybe a bit of oral would do her good as she still has work to do. After a couple of minutes of walking around the office, trying to do things to get rid of my boredom, I went to sit next to her to have a chat. It started raining and we started to speak about small things and time dragged on as I was gathering up some courage to take action. I eventually started asking her questions about her sex life and when she will keep to her word of fucking me since that is what she was planning on doing when she saw my dick. She got all quiet and shy and told me I should wait, wait until next year. I then told her, that we should at least try something, as we are alone and it is in the office, at work. She looked at me and asked what I had in mind. I told her, that she should continue working as I will be doing the pleasuring from under the table. She gave me a nod of acceptance and with that, parted her legs open as I got under the table in between her legs. I found that she had no panty on and she was already wet. She moved herself a bit forward on the chair to sit on the edge to give me easier access to her pussy. As she got back to work, I slowly started moving my hands up and down on her silky-smooth legs, leaning forward as I kissed my way to the center. I continued kissing her, around her slid, making sure I kept it short and light before sticking out my tongue, slightly touching her slit as I felt her body starting to rock from the teasing.  After having my fun, I moved straight to her slid and started licking her, I kept to a slow rhythm, up and down, making sure to brush my tongue against her clit a couple of times. Her moans encouraged me to continue, and when I got to her clit again, I started sucking it into my mouth, giving it as much attention as I could. While sucking on her clit, I moved two of my fingers to her wet slid, pushing them in gently all the way. My colleague put her one hand behind my head and this encouraged me, even more, to make her cum as I knew she was getting close. I started sucking a bit harder on her clit as I pushed my two fingers harder and faster into her pussy, in and out, as her moans got louder, not stopping one bit. It wasn't long, and then she came, moaning load and holding my face against her pussy. After she wad done and I was satisfied, I licked her slit, cleaning it before I got back up from under the table. I told my colleague that that was a great way to say goodbye and that I will be seeing her after I come back from leave, and with that, she gave me a hug, and I left the office. PS: Half of the story is true and the other half is just a fantasy that played out in my head.
