She has the nicest set of lips on the planet! Not too mention that she is a knock out! I always have to jack off after looking at those beautiful lips!
But doesn't that sort of defeat the whole point???
Oh, well, I guess when fake tits are considered just as real as unaltered tits, it's not worth getting into it.... except to say that if Katsumi needs to stretch them out, then she DOESN'T really have big pussy lips. Which is great for those who don't like 'em or don't care, but a minor letdown for the rest of us....
