Flooded In and Horny

I 22 live outside of our town on the family farm; it had been raining all week and the road to town was flooded. My parents were in the city, my mother undergoing tests, I was home with sister 19. Nothing to do, animals had been checked and nothing else I could do because of the rain. Boredom soon set in as the internet was out a usual thing in these parts when it rained heavily. My sister was also bored and were started mucking about, one thing led to another, and we became lovers. It didn't stop at one and we regularly fuck every chance we get since then. But we do have other partners, but the sex between us seems more special. Maybe because it's forbidden, but unless we find a more special partner, we'll continue our forbidden passion.
