Summary: Your boyfriend (the speaker) surprises you with a gift: some bran new makeup.
This is isn't exactly an entirely altruistic act, however. Nor is the gift *really* for you, as much as it is for him.
Because if you want the makeup, you'll have to be his filthy slut for a while.
He's going to doll you up so you look beautiful... then utterly ruin you until you're nothing but a messy, cum covered slut.
