I don't really have people to talk to about this stuff so I guess I'll just post it here. I'm 31 years old, and I have a 28 year old sister. Our mother was a quiet lady who very obviously felt like she had made a wrong turn in life. Our dad was an angry man who drank a lot and would lash out.
When I was 11, our mom left. Ran off with another guy. Probably has a new family by now. But she left us behind. Without her around, Dad started to drink a lot more and he got a lot angrier. Usually just meant he would beat whoever looked at him wrong first out of the two of us. I don't remember when exactly, but somewhere in there he started sexually abusing my little sister. If she refused he would give her absolutely vicious beatings. In the area we were raised, nobody really batted an eye at beating your kids. There was a very "not my business" attitude towards it, so nothing was ever done. We lived pretty far away from anyone else, too.
The other thing about our dad is that sometimes he liked to watch. He would try to make me do sexual things with my sister. I refused and would get beaten for it. Sometimes he would fuck her himself after. Eventually I gave in and would do certain things with her. Never full-on penetration but we decided between us that if the choice was between doing something minor with me or having sex with him, she'd rather do the former.
One day, I guess I would have been 13 and her 10, there was just this perfect storm of events. I was angry. Our dad was angry. My sister resisted him and he started beating her harder than he ever had. I grabbed a small kitchen knife that was nearby and just went after him. It wasn't about wanting to protect her, I just wanted to kill him. I got him a couple times before he started in on me instead. Even with a weapon, he was a lot bigger than me and a lot stronger than me. Sister ran outside, half naked and beat all to shit and I guess a car pulled over for her. Some guy I'd never seen pulled my dad off me.
We ended up living with our grandparents while he was in prison. It was nice. Grandma was always really sweet and taught us a lot about cooking. Grandpa was the gentlest man you'd ever meet and loved to work on cars. The whole thing with our dad fucked us both up, though. I've got some weird fetishes now and I have trouble with my emotions. Mostly with opening up to people. It made me into a hard person, I guess. My sister's the opposite. She's like a timid little mouse and is still terrified of anyone but me. She had her first boyfriend earlier this year and was so proud, but I'm told they broke up over a fight because he wanted her to call him daddy in bed.
I don't really like talking about this stuff but he's been out of prison for a couple years now and it's pretty prominent in my mind right now because he's been hanging around my sister's home a lot. Kind of stalking her, I guess. She's been staying with me for two weeks now out of fear of him. It's depressing to see just how much damage he did to her and it makes me wish I'd done a better job of protecting her from him.
