Party Night

It had been raining all week, and it continued into the weekend. Stuck at home with my sister, 22, we couldn't go anywhere; the roads were flooded. We had lived together since she moved to the city last year. I (25) had just lost my rent buddy and had a spare room in the old apartment I rented. The block we lived on was above the water, but there was nothing to do there besides watching TV or using the internet. All our neighbors were old and not much into partying. Able to work via the internet, so being stuck at home didn't bother me that much. My sister worked several jobs; all were closed due to the flooding. We started mucking about Friday afternoon, mainly from boredom. But we got more adventurous, you could say. Ending up in bed together fucking, we continued our lovemaking, as we call it. She takes precautions, and so far, no problems.
