An Unexpected Weekend Invitation from My Boss

My first threesome -part 3
I straddled him. We kissed passionately. His wife, my boss came in and said"Good girl"..."have fun "... she went back to the kitchen. We fucked everywhere in that bathroom. I was now getting used to his size.i felt like my pussy was his now. I came so hard I made him cum too.He cursed and laughed. He kissed me. We finished showering and went to the kitchen.I kissed my boss and thanked her again. She said" Did you have a good time? Let this stay between us huh! Anything you need at the office let me know and btw consider your job permanent". I grabbed her hands and said" you really don't have to ". To which she replied "i want to... And you are welcome to come spend a few days with us anytime...open invitation my sweet girl". I hugged her and I decided to stay a few more days. That evening he dropped me home . I took some clothes and he brought me back to their house. We watched TV, played games, made love, fucked and after that faithful Halloween week I would be at their house pretty much every weekend until they moved some years ago to Denver. I made the trip twice but it was too much for me .They came to me a few times but we had to go to a hotel as I have a roommate lol
