My new Job

I'm Ross 32 single and I've got a new job overseas last year and my sister Karen 25 had a dead-end job wanted to go with me. But I knew if I took her with me I would be asking for trouble, Karen had seen the conditions of my employment and that there was a house included as part of it. Karen is a nice looking girl but gets into trouble partying too much, I didn't want her getting into trouble and me having to get her out of it. Also, she couldn't speak the language and would have to look after her. I told her I couldn't take because I would need to concentrate on my work. She then waited until we were alone and made me an offer of sex if I would take her with me. She said she would my lover and I could do anything I wanted with her sexually and I said someone might find out and it would cause a scandal and I would lose my job. She said nobody will notice and she could pretend to be my wife. I said I would think about it and later when I was in bed she came into my room naked and got into bed with me. I've not had much luck with women, well none actually and have paid for the fucks I've had. With her playing with my cock and her naked body, I had sex with her. Then I had to take her with me and for the month before we were to leave she joined me every night in my bed. Our parents were a little bewildered I was letting join me, but they were also happy I wouldn't be alone there also. I told Karen she couldn't play around there as it would ruin my career and she agreed to behave herself. We've been here for nearly seven months and Karen is behaving herself and is sleeping with me every night. She gave a scare last month saying her period was late, but she isn't pregnant.
