Girls who get dumped often come to my sister to talk about their problems. But my sister has a really low alcohol tolerance, so even if I say, "I'll join you in your drunken daze," she falls asleep right away. As a result, I, who share a room with my sister, end up listening to her talk... At first, it's just a story, but in the end, my sister's friends, who are drunk and dumped and in despair, always want my dick.
