Is it normal that i had sex with my sister?
I've been staying in my sister's apartment for the past few weeks while looking for a new place of my own.
We're both single and unattached at the moment, and had talked briefly in the past about how both of us were frustrated by the lack of "action" in our lives.
A couple nights ago, we were watching True Blood and had been drinking a bit (bad idea!), and a really hot sex scene came on.
It became apparent that both of us were pretty turned on by this scene, and we kinda began looking at each other. Then we kissed and touched a bit.
She was apprehensive and said, "I don't know, I have to think about this." I was feeling pretty bold, so I said "Okay, while you think about it, I'm going to do this..." and I pulled one of her tits out of her nightgown and started sucking on it.
Finally she just said "Fuck it, let's do this." I grabbed a condom, and we did. It was one of the strongest orgasms I've ever had in my life.
We haven't said a word about it since, and I obviously can't help replaying it in my head and trying to figure out what to make of it.
Is this normal? A freak occurrence? Am I a terrible person? What's up???
