After the final exam of the 1st semester, my best friend and I had a few days to relieve stress after a long time of worrying and studying hard for the exam; After discussion, I accepted his invitation to go to his house to play and for a few days, of course, I asked my family for permission first.
My friend lived with his sister, his parents died early, although there were only 2 people in the house, but when I walked in, there was a very familiar feeling, as if in my previous life he and his sister were from the same house. We greeted and quickly chatted and joked with each other. While having fun, I suddenly realized that my friend's sister was very "delicious" and attractive.
I still talk normally, live comfortably, but in my heart I am interested in that beautiful sister. And while they were asleep because they were tired of playing, I took all the courage to touch her asshole and unexpectedly, beyond my imagination, my friend's biological sister was extremely lewd...
