Desire out of control

I don't want to bore you with the details of how we came to be, but i'm in a relationship that's considered a serious taboo. I'm a guy, 30, and she's 37, and also my older sister. We've been lover for most of this year.
It started off fairly "normal", as far as that can be said for that kind of relationship. At first it was just kissing and dry-humping, but the attraction grew so much that it wasn't long until we moved on to protected intercourse.
Before I continue, let me say that both of us were very experienced and fulfilled, sexually speaking... yet, when we began our affair, something clicked. If there's something we both agree on, is that we'd never had sex this good before. It's fucking amazing. To the point that, at least in my case, now I can't picture sex being so good with anyone else.
That thought started the first time I came inside of her. Despite she being on the pill and me using condoms to be safe, we agreed to never do it... but then she decided to let me go bareback and cum inside of her... and it was a like a religious experience, so to speak. my sister and I felt much more connected than ever before after that.
And from that moment, things have slowly spiralled out of control, at least for me. We often go away together on weekends, so we can date out in the open like any other couple, but nevertheless we used to show some restraint in public... but then we started to kiss more frequently, then more passionately... then I masturbated her to orgasm in a park, then we slipped into the bathroom at a family reunion to fuck while our mother was downstairs.
Even still, for her it's all fun, the most intense experience she's ever had... but I'm not sure she wants much else. Me, on the other side... I've started to desire her on unhealthy levels (as I said, I'm so fixated on her I barely even look at other women).
A couple weeks ago, we went away on a "special ocassion". she wanted to give her virginity to me, so I became the first man to ever fuck her in the ass (it was my first time doing it to a woman, too), and I don't think I'll ever have a better first time experience. we both enjoyed it so much that we've done it that way almost exclusively since.
that's when I lost control this past weekend... we were at it and I felt such lust for her that I started becoming rougher... and rougher... until I became agressive. I was in her ass, doggystyle, and then I started slapping her ass harder, then I forced her face on the bed, and started pumping much harder. Lucky for her I didn't last long that way, because I could clearly hear she was hurting, but I was too horny to stop.
She was mad and scared afterwards, obviously. I apologized by saying that I just got too carried away, and she admitted that while she found this sudden sex drive a turn on, she wanted me to talk to her first.
Thing is, I've had darker thoughts and fantasies this last few weeks, the kind I never even had with other women before, only her. She's not into dirty talk, but calling her my filthy whore would turn me on so much. I've had fantasies where our friends watch me fuck her while calling her my whore. There's also the "more conventional" things, like wanting to call her "my woman" in public, even in the face of our family. and also, I'd like the thrill of impregnating her, which I know is sick, but the taboo just drives me crazy... and I don't know how to just make this thoughts go away.
