I think Kylie and Kendall are both very pretty girls. In fact, I've found myself jerking off over them more often this season on "Keeping Up with the Kardashians" than I do over their big sisters. I'm really looking forward to seeing more from them in the future.
Justin just has a boner for Kim like most young guys his age, it's pretty hard to blame him. Even though Kim's old enough to be his mom, I still think it'd be pretty hot to see them together as a couple.
