I rented my apartment out to a friend of mine about 3 months ago and he asked if he could move in a couple of people to help him pay is rent. I told his that it was ok and not a problem as long as the neighbors are not disturbed with loud noise. He ended up moving his friends sister in and ever since then they have became a fuck buddy to each other.
Needless to say his friend is not very happy because they are about 10 years in age apart. She cooks, cleans and runs all of his errands while he is out at work which helps him out greatly. They are always flirting with each other and start drinking on the weekend and they will disappear in the bedroom for hours upon hours. The next day when we see both of them they always have a huge smile on their face, except her brother!
