Plump (is thick still used, it's a compliment when describing a cock, should be the same for women), nerdy girls seem to be the secret sluts/courtesans of the world. Luckily some of them are now allowing their secret to vidom. We're lucky since nerd sluts tend to be shy and monogamous, thus only their men are aware that their woman is one amazing fucker and cocksucker. She not only fuck dances over your cock, but she acts like being given your cum is a special event and swallows it like ambrosia. Complimenting your secret slut encourages her to become even sluttier, more sensual. It's well worth the effort.
To give the woman a facial is a poor attempt to humiliate her, to display a false sense of superiority, finish orally as a.gentleman, she's doing you a favor, grow up.
