My sister is an extreme older brother, extremely anxious and interfering! It was annoying when she interfered too much, so when I pushed her away with an antagonistic attitude, she became so depressed that she cried, locked herself in her room and didn't even eat. I had no choice but to say "I'll listen to whatever you say", and I had SEX after being extremely sticky. When I got on top of it and shot my cum into her vagina over and over again, I cried with pleasure. I will try to treat my sister well from now on.
