HUNTB-427 Cousin begged her brother to fuck her

My sister is a very extreme older brother, extremely anxious and always intervening! It's really annoying when she intervenes too much, so when I push her away with a defiant attitude, she becomes so depressed that she cries, locks herself in her room, and even refuses to eat. I have no choice but to say, 'I will listen to anything you say,' and I was in a very tight situation afterward. When I got on top of it and had an orgasm inside her time and time again, I cried out of joy. I will try to treat my sister well from now on.
