We work with 4 other people in our store and they don't usually venture upstairs unless they need stock, a cup of tea or to talk to us if we are doing admin work in the office. My boss and I were downstairs and only 2 of our colleagues were working with us today. We had established boundaries that basically nothing is ever going to happen between us relationship wise, however we can do whatever we want to one another, no strings attached. I didn't know if I would or could fuck the hell out of him, because of his partner, I would feel so bad.. Temptation and sexual frustration made clear that this would not be the case! We were talking to one another about how we liked to be fucked, doggy, on top, foreplay and for how long. . He has an extremely vivid imagination and when he tells me the things he would do to me, there is so much detail involved, it is as if it has actually happened. He made an excuse to go upstairs and I mumbled about going to the toilet. We have the CCTV screen in our office so we can see what everyone else is up too downstairs.. He was sat down by the desk and I sat next to him, not a second passed before we started kissing. His hands ventured all over my tight body. I couldn't help myself and started undoing his trousers already on my knees. I started to tease him by tickling the tip of his cock with my tongue smiling directly into his eyes. He was going to enjoy every second of this. I suddenly deep throat his entire cock, he moaned and grabbed my head. After sucking his cock he lifts me up and bends me over the desk, pulling down my trousers and pants he starts to lick my wet pussy. I moan and grab his cock in my hand and direct it to the entrance of my throbbing tight hole. He slides it in and it feels so amazing. He goes slow and then starts to pound me harder and faster. We don't have long before our colleagues would start to become suspicious.. He grabs my hair and my back arches, I turn to look at him biting my lip. My fingers scratch down the desk as I try and hold myself upright. It doesn't take us long to cum, the excitement was too much to hold out any longer. His load shoots into my pussy and he pulls out. I stay bent over the desk in complete awe.. I felt very satisfied to say the least. The feeling of his cum slowly dribbling down the inside of my leg turned me on I wanted to do it again.. I clean myself up and wander downstairs leaving him in the office.. I give him a cheeky smile into the CCTV as I know he will be watching..
