Sibling Sex Guilt

There were several incidents of sex play with my younger sister when we were kids.
I got her to show me her vagina when she had just turned nine and in exchange I let her watch me, in my early teens, just jerk off to it as she watched.
It could only happen when our parents weren't in the house, which was not often at all but when we were alone I'd get her to do it as we looked at online porn in my room. I know that by the third time we did it she asked me to lick her like she saw on one of the vids so that sort of became part of it as well. We did it like six or seven time over like almost two years because of the privacy needed. Then she just refused to keep doing it and fearing she'd tell, I backed off. 

I was 9 and my sister was 10. We shared a room and I knew she used to masturbate because I could hear her when she thought I was asleep. So one night when she was doing it I got out of bed and pulled the sheets off her and told her I wanted to watch her. She continued fingering herself and asked me if I did it too and I said yes. We ended up watching each other and after a while she got between my legs and started licking my pussy. I was so wet I still remember her tongue inside me that first time. She said she’d learned this at a sleepover. We ended up in a 69.  After that first time we ended up doing it all the time. It was easy because we shared a room. Nobody ever found out. Neither of us ever felt bad about it. 

I was fourteen, crazy horny. I was supposed to have been babysitting my youngest sis who was seven. I talked her into participating in cam to cam chats on omegle. She saw erections for the first time. I showed her mine. 
We continued on chatting, connected with other kids and all of us "showed" on cam. It seemed we were both aroused.
I talked her into letting me do anal sex to her. She barely tolerated it and told me it was hurting but I didn't pull out until I had squirted my semen in her. 
It got incredibly awkward once I was done and she was very annoyed with me and I gave her like my best dvds and earphone as a bribe to not tell. 
I literally lived in absolute fear for almost a year before she asked me to show her how to access porn sites and she'd never tell. I showed her. I know I shouldn't have done any of this but I did and it has been just slowly eating me up. My sis and I barely say hello to each other on the very, very rare occasions that we are in the same place at the same time. It's still awkward.  

I know I should not have done it, it was wrong. When I was a horny thirteen year old, I showed my youngest sister porn on my laptop when she was eight. I got her to jerk me off all the way as we watched. It happened only that one time. As adults we do NOT talk about it but I know she remembers it just as much as I do. 

You did it yourself

You told him to do it
