You're so addicted to eating your own cum that sometimes you think about another man's cum. What it might taste like compared to yours, what it'd feel like to have it splash around your lips and tongue. You're starting to think about your friend's cum... the friend who gets all the pussy. You used to be jealous of all the girls he got, but now you're jealous of the girls who eat his delicious cum. You know he has a big dick and now you can't stop thinking of it, can you? You want to eat your friends cum.
