I'd bang either one, if given the chance (which isn't saying much with my standards), but if I had to choose one over the other, I'd pick Jolie. Basically you have Jolie amazing lips on one hand, and J-lo's ass on the other. I do love big butts, however, they are common. All I need to do is go to my local McDonalds to find a woman with a fat ass. You don't see too many woman walking around with lips like Jolie's. They were made for sex.
I'm not to bothered about the incest thing. If she'll do her family, she'll do (and probably has) anything.
