I.i.n to be turned on by seeing my sister have sex with her boyfriend

My sister and her boyfriend were alone in our house, looking after our baby brother and I came home to find them having sex in the living room.
She was naked and they didn't notice me watching and I creeped out again before they saw me.
We have a normal sister/brother relationship. Its a bit love/hate but I hadn't seen her undressed before and she has a great body.

I dont get turned on by her as such, but I did by her nakedness and I now think a lot about her body and I cant shake that image of her being fucked.
I have started imagining myself doing to her what her boyfriend did and I feel quite jealous of him.
Is that in any way normal?
Shes 16 and I'm 22.

    This is normal. Males are visual and like to see nude female. So it is your sister. Watching sex is a big turn on for many. Enjoy this any way you can.

    I have seen a video tape of my sister and her husband having wild sex,Neither one knew I had seen it,And it was a very big turn on for me. I viewed it for almost a week before they put it back in their bedroom. I never wanted to have sex with my sister but had no problem watching her taking care of business.
