With my 18-year-old country friend, she wants sex every day since she moved in with me, her boyfriend is growing potatoes

She is my friend from the countryside who I met when I went to visit some relatives of mine, she was a girl next to the countryside with whom we used to play, the years passed and she spoke to me again through social networks, at first I did not know who she was until we met, she told me that she had just turned 18 and wanted us to see each other like in the old days, She didn't go beyond the first date and we started, she confessed to me that she always felt something for me and that she was very happy that I was her, recently she came to live in my city and we met just to whenever we could, her parents still live in the countryside and they don't know anything.
