Daddy, I don't mean to be rude, it's just that your dick doesn't satisfy me! You have a small nub for a cock, and it can't make me cum. So I have to use a fake cock that's much bigger than yours! But I don't want you feeling left out, you can jack your own tiny little cock off while I suck, fuck and orgasm all over the fake one. God knows you could never make me cum!
