The housekeeper that gets revenge and has a large secret

I’m a businessman that works very long hours and can always need help around the house.
I called a service and they sent over a woman named Tessa. Tessa was a woman from from Ecuador who needed a job. She was not most attractive woman that I had ever seen as she was about 5’7, black hair. She had small breasts. I guess that I was not hiring her for her looks but rather to clean the house.
About six months later, I came home early from work. I was very horny that day so I put on a porno movie. I began to pleasure myself and I realized that Tessa was in the other room. She watched me playing with myself. I continued to pound away as I saw her hand reach down to her private area. The thought of pleasuring herself while I did the same excited me to no end.as I came all over the bed. I called into the bedroom and told her clean the sheets.. Tessa said you bastard in broken English. She took the sheets and put them into the wash. She said “you are a pig and someone will teach you a lesson”.
She worked for my for another six months. All we did was argue as she stated that all Idid was treat her lousy. I would talk down to her.
I had a large party one Saturday, I need help to clean on Sunday. I called Tessa and asked her to come over. She came over and she had a large bag with her. What do you need that for? She laughed, just somethings that I may need. She started cleaning when I called to her, bitch get in here, I need my drink. I took a sip of my wine and that was the last thing that I remember. When I woke up, I was flat on my back completely naked.
