If you have not read the first two chapters I would recommend you do, as this is a continuation of the first and second chapter.
Driving home I am trying to think of a way to explain to Matt about Karen joining in our play time. I decided to just tell him the truth, that she caught me gathering the supplies and I told her all about our play time, and hope he isn't mad at me. Luckily when I got home Matt was sound asleep so I could put off the conversation until tomorrow, or even later as I don't work again until Friday evening, and won't see Karen until then.
The next night as we were laying in bed I mentioned to Matt that I had all the supplies we needed for another catheter sex session. I asked him if maybe Friday evening he could wait up for me after my shift, and we could play. I then began explaining to him about Karen catching me raiding the storage room for our supplies. He was at first worried that she might turn me in for taking the catheter and the other things, so I used his fear of me getting caught to my advantage, to help sway his interest in letting her at least watch or maybe help.
Although she never said anything about turning me in, I told him she had promised not to say anything if we would allow her to watch, or maybe even help with the catheter. I did remind him that at the hospital we always worked in pairs, two nurses, usually female, when catheterizing a male patient, so it would be more realistic, and not out of the ordinary, if she were to watch, or even help.
Matt was really hesitant about Karen watching, let alone helping, but I think he was worried about her catching me taking the supplies. After talking about it he did finally decide that it would be ok for her to watch to keep her silence. I almost squealed with delight when he relented to letting her watch. I knew it would be even hotter for me, and probably him too if she was there. I also was pretty sure that if she helped out he would not object.
Friday at the beginning of our shift I cornered Karen and asked her if she wanted to come to my house after work, to play. A huge grin on her face answered my question without her saying a word.. We agreed to meet in the parking lot after work and she would follow me home, as she had never been to my house. When she approached me in the parking lot I asked her to sit in my car for a minute to talk.
Once in the car I explained what I had told Matt about her catching me in the storage room and, to keep her silence about the theft she wanted to watch. Again Karen gave me a big smile knowing that she understood how I had gained Matt's cooperation. I cautioned her about being quiet when we got to the house as the kids would be sleeping. As she followed me home I began to get turned on and wet just thinking about how hot this was going to be.
Karen followed me quietly into the darkened house and I led her to the bedroom and closed the door behind us. I had instructed Matt to be in bed, dressed only in his briefs, with the nightstand lamp turned on. I had purposely worn a skirt to work, a rather short one at that, because I knew we would be playing. Karen usually wore a skirt to work and tonight was no exception, and hers was shorter than mine.
We immediately went into nurse mode and began explaining to the "patient" that we were here to insert a catheter for his surgery tomorrow. I had Matt move to the center of our queen size bed so I could kneel on his right and Karen could do the same on his left.
Before we took our positions on the bed Karen pulled the sheet that was covering Matt's lower body all the way down past his feet. While I was opening the tote bag and retrieving our supplies, she had him lift his hips and she slid his briefs down his legs and completely off his body. He seemed embarrassed to be exposed to her gaze, and his penis was flaccid.
