Katja wears glasses, so you know she's smart. Her IQ tested at genius level in high school. Of course, that's after she gave the guy adminstering the test a blowjob and swallowed his cum. Genius or not, Katja is smart enough to know that it's not prudent to let guys cum in your pussy. You might get knocked up and have to go on welfare. No, much better to offer up your tight ass and let him shoot inside your colon. Then the worst thing you have to worry about is sperm running down your legs every time you fart!
