I was chatting with a friend of mine. She and I are very open about our sexuality and although she's happily married with two beautiful children I'm her "free card". She can sext with me and we had some IRL encounters over the years with her husbands consent. Anyways I was chatting with her and at the time her husband was on a trip with some of his buddies and she was very horny. We started chatting when I was at work and she loves to tease me when I'm in the office...since she is also very beautiful I was triggered very easy and started sending pics of my bodily reaction back...

At this point I'm still at the office and frequently people come to my desk and ask stuff. A coworker came in and wanted to talk about a project and I thought I closed my screen but didn't so she got a good view at the chat with a pic of my raging boner in perfect view. It was very clearly me in that pic and while we were talking I could see her eyes darting to my phone on the desk and her blushing a bit. I realised my mistake when she was already gone and I saw my phone still on with the chat open. At first I was mortified and concerned that she would say something to my boss but she didn't, she just couldn't really look me in the eyes without blushing for the rest of the day.

As it happens we had a summer festival organised by our workplace that evening, which is why I couldn't just hang out with my friend that night. The party was good and everyone enjoyed themselves and after the boss and his wife left we started to let loose a bit. Alcohol started flowing easier and we were just having a great time. I would go out frequently to smoke, especially while drinking I probably spent more time outside and talking to people then inside. At some point I was standing outside alone and my coworker that saw the chat got over. She was already very tipsy and the alcohol fueled a brave outburst. I could see her mentally preparing herself to confront me. She told me she saw my chat and that she was wondering what I was doing and why at work. So I told her about the situation and that I'm in a fwb situation with her and another woman I know from my wilder 20's. She started to tell me how her bedroom is dead and she feels like her husband doesn't desire her anymore and how she misses it. One thing lead to another and we made out in one of the empty offices. The risk of getting caught and her knowing her husband cannot find out made her really horny and easily startled at the same time.

She had a kneehigh skirt and a button up blouse. I started playing with her amazing c-cups, sucking on her nipples and kissing her neck and chest while slowly rubbing her pussy over the skirt. I could feel her squirm and twitch from my touch. Her breathing started getting heavy and she had a tight grip on my hand dick though my pants. Started getting on her knees but I stopped her... since her dead bedroom I wanted this encounter to be focused on her needs. I told her to lay down on a desk that isn't in direct eyesight from the door and told her to get rid of her underwear. I sad down on the chair in front of her and started kissing her thighs and slowly caressing her pussy... unnecessarily teasing her by massaging the outside of her lips and letting my kisses wander further inwards. I spread her lips and started softly licking between her inner and outer lips. She was very wet at that point and moanded a bit too loud but I guess she wasn't really aware of where we were. I started sucking on her clit and softly letting my tongue circle it. She gripped my hair and her moaning became lustful and dangerously loud. I started quickening my tongue play and it wasn't long before she came... apparently she wasn't lying about her dB because she came rather quickly and it seemed like she came out of another world...she even cried a bit. After comforting her she was very interested in comparing what she saw in the picture to the real life version. Having a dead bedroom didn't seem to have lessened her blowjob skills. She got on her knees Infront of the chair and started blowing me...since I've been horny all day from my friend teasing and her orgasm I was very near cumming very fast. I stopped her before I came because I definitely wanted to fuck that wet pussy and I wanted her to have the joy of getting fucked she was craving.

She layed back down on the desk and I put on the condom I usually have with me. Her pussy looked so inviting and her amazing tits were out of her blouse. I started fucking her standing Infront of the desk. Thankfully no-one was around since the party was on another level of the building because after an initial slow getting used to I couldn't not fuck her hard and fast, taking her arms for that bit extra pump. Her legs on my shoulder and her tits jiggling on front of me was a very hot view. Her moaning was loud and I had one ear open for possible surprises...well at least as much as I could spare the concentration.

The problem from before arose again, coupled with her obviously enjoying getting fucked I could feel my orgasm building. I told her this and she asked me to cum inside her...she even said please. Even if I wanted to I couldn't have hold on much longer and came "inside" her. I still had the condom on of course but she loved it...I had a good grip on her forearms and could feel her nails digging in when I came.

I was a bit embarrassed from cumming so fast but she said she hadn't had this much fun in a long time and since we were in our office building it may have been better this way. Some people would start noticing our absence soon. So we got dressed and headed back to the party much more relaxed...

We started fucking regularly after that...whenever she could find a reasonable excuse for getting out alone and I got to redeem myself...
