Believe it or not, she's my sister. We've been having sex since we both were teenagers. When we were on our 20s our mother caught us in our grandma's basement. After that I decided to leave and I joined the Russian army. My mother made my sister got married with a looser and as expected it's not an happy marriage. Our mother never told anyone about my sister and I, she died 5 years ago and I decided to return to my home town, where my sister lives with her husband and kid. Now we met when I pick her up from work, we do a quick stop by the road and do it in the car.
