@XL with Chiho becoming the most searched person on the internet, and with the dad already being suspicious, she is bound to find out really soon, but it doesn't matter as long as the brat can stick it out to his principles of having a big titty gf, which i dare say is one of the most noble principles anyone can stick to.
Dad is too busy being proud that his son got him such a fine lady. He may have to sacrifice points with the wife but any good father would do that for his son to bang some hot girl in a relationship.
Okay, an eight year gap isn't that bad, and in Britain, parts of America, and parts of Europe, the age of consent is 16. It's not a massive deal, my dude.
