I've seen your wife. I've had better.
//I've never seen his wife.
Seriously, I think that girl is hot for 2 reasons. Big boobs. And she looks more like the girl next door kind of hot where the girl is just a cool girl who happens to look good as opposed to really trying to (looks can be very deceiving on that, but she does have that look). And, oh yeah, big boobs, did I mention that?
