I put the book down and watched for a few seconds, wondering why the mood had changed. And then J gave a sort of little gasp and a groan and I realise... that she was wanking him off under the covers.I didn't know where to look, but K was looking at me, and smiling, as her hand continued to move up and down under the duvet. J looked as surprised and embarrassed as I was, kind of staring at me. I might have said something and tried to ignore what was going on; I can't really remember, because. I was sweating a lot by then. I touched her nipples and started caressing the boobs. She started moaning. I was also kissing her nipples while caressing her melons. She was enjoying the act and was giving handjob to me simultaneously. I made her lie on the floor and then started kissing her on her neck. She held her hand on my back and started pressing me against her body. After a few minutes, I asked her to come on her knees.I then took my dick near her mouth and asked her to suck the dick to. I put one hand on her shoulder, partly to see better, partly because I liked the idea of a good excuse to touch her. We had had no physical contact at the office to speak of, but I had found her attractive. I started to talk to her, to help her relax, and as I talked to her I gently massaged her shoulder. Then I put my other hand on her other shoulder and started to massage it as well. This was actually sort of innocent -- I wasn't trying to make a pass at her, at least a serious one --. They had both just finished their orgasms and hurriedly threw their clothes back on. The voice outside the care identified themselves as local authority. When the pair had dressed they cautiously exited the vehicle only to see a car leaving the area and not another soul was in sight. Trent made sure Nikki got into her car and back to her home safely. It was the strangest thing and they later blew it off thinking it was teenagers being silly. Another time, similar location, daylight, Nikki was.
