I came home yesterday and my two friends were waiting for me. My younger brother was there, he is 14. He let them in and they were waiting for me. We went for a walk and when I came home, he told me that they talked for about 15 minutes before I came and when I came back, one of them kissed him on the cheek and said that she would fuck him when he grows up. This girl is 21. Should I talk to her about this incident?
