Horse Riding

I'm lucky as I failed as a student and as such ended up as caretaker of the family farm. Which is mainly for holidays away from the city for the family, no crops or animals raised and only horses kept on the farm. I just make sure everything is fit for purpose and which isn't that hard to do and means I have to ride each horse regularly, so they are ready for family visits. I love horse riding. So, perfect job for me and I have plenty of time to do whatever I want to do myself. My only sister came for a visit in 2020 and she got caught by the pandemic lockdown and had to stay with me her youngest brother. The rest of the family were in the city, so we went horse riding and more riding and swimming in the dam on the farm. Over the lockdown period we were always together, one thing led to another, we started fucking. It started while our horse riding and it was hotter than usual, we went for swim and started playing and ended up fucking. Of course, we're the sexiest people ever to be born. But we're not and we don't care either way about how good you look. But we have continued a fairly regular sexual relationship. Whenever she visits, we fuck at least once, she takes precautions. Even last month she came from break planning her wedding. She marries early next year and says she is always willing to fuck her younger brother.
