Last night my brother came home drunk and climbed in my bed with me sleeping on side. Sometime during night, I woke up with him entering me. By the time I realised what was happening, he was inside and having sex. As I protested, he came inside me and rolled back to sleep. I stayed awake the whole night. In the morning till now, he's acting like nothing happened. I'm scared that I might get pregnant. Our parents are dead and we live on our own. I don't have anyone to talk to.
