There was a knock on the door, and it was my girlfriend Carla with one of her colleagues Sarah who I’d only met a couple of times as she was new, to do some work, as she said it was too busy and noisy in the office to get it done, and as I had a better laptop, she wanted to use mine if that was alright.

So I said, “ that ok, come in and I’ll make the coffee, and you can get on with your work.” Carla walked in ahead of Sarah, and as Sarah walked past me she pinched my ass and whispered, “ I’ve heard all about you, I’ll have to try you one day, ” and winked at me, I just said,"Promises, promises,” as they walked into the lounge.

I walked through the lounge into the kitchen to make the coffee. Carla sat down on the sofa, and opened the laptop and started work, Sarah was obviously feeling a bit daring and came right up to me, and said, “ I’ll give you a hand” and she slowly slipped her hand down my body and stopped just above my shorts.

I whispered to her, “ you wouldn't dare,” and with that she continued down and squeezed my cock through my shorts, which made me get an instant hard on, then she released it and just smiled at me, saying,” you are big,” I started to wonder if I’d been set up again. So as Carla had her back to us, I thought I’d give it a try, and I stood behind Sarah and I reached around her and placed my hand at her neck and slowly slipped my hand down between her tits.

Then my hand went down over her stomach and stopped just under the waistband of her skirt. Then she said repeated those three little words, "You wouldn't dare,” now that was a challenge I couldn’t turn down, so I slipped my hand up her skirt and into her thong, and my fingers slipped between her legs into her soaking wet pussy, and she let out a little moan in shock and pleasure as my fingers slid into her pussy.

I froze for a minute and looked to see if Carla had heard Sarah’s moan, and I don’t think she did as she just carried on working, so I didn't move my hand, and after about a minute Sarah started to slowly push her ass back into me and I started to circle her clit with my thumb. She then reached back and somehow got her hand in my shorts, and around my cock. She worked it up and down slowly while rubbing her ass back into me, it was almost like she was trying to press my cock into her.

We continue like that until I felt her pussy clamp down around my hand, and she began to shake, I knew she was having an orgasm, and her tempo increased while stroking my cock. Then Carla said, “ is that coffee ready yet,” so we released each other and Sarah went into the lounge with their coffees, and they continued to work, while I sat in the kitchen with my coffee, before taking some rubbish out the back.

When I came back into the kitchen Sarah was leaning over the kitchen unit, going through some paperwork, the kitchen cabinet separates the kitchen from the lounge, where Carla was on her laptop with her back to us. And if she looked back she would only see us from the shoulders up, so I walked up behind Sarah, dropping my shorts and getting my cock out, and as I got behind her I lifted her skirt.

She was reluctant at first until I pulled her thong aside and put two fingers into her pussy, I think she thought I was just going to finger fuck her again, but I was making sure she was well lubricated for my cock and continued to finger her until she was. Then I grabbed her hips and guided my cock into her soaking wet pussy in one thrust.

Sarah reached behind and tried to push me out, saying, “Carla will kill me,” but I continued to thrust in and out of her pussy. Eventually she began to push back and enjoy it, and she put her hands on the counter and bent over more, as I continued fucking her from behind I reached around and played with her tits. We were as quiet as we could be, but I couldn’t believe Carla couldn’t hear us a little, so I thought yes it’s another set up but who cares, then I realised why she hadn’t heard, she had ear pods in listening to something.

So I continued to fuck Sarah, and she reached behind and pulled me down to her lips and kissed me, and it felt a whorish kiss, and I knew, she was close to cummin. Then within seconds she started to cum, and I felt it gush over my balls, and I also couldn't hold it any longer, and with one final thrust, buried my cock all the way inside her and exploded, filling her pussy with my cum.

Every spurt of my cum inside her made her twitch, until she just leaned over the counter to catch her breath shaking, we then broke our embrace and I pulled up my shorts, and she picked up the paperwork, and said, “ for fucks sake, please don’t tell Carla,” and went and sat back next to her, with her pussy full of her boyfriends cum, to continue their work.
