Well, that would depend on “why”.
If I’m jamming two or three fingers down her throat, thus making her twitch and shudder and cry, and she happens to drool on me in the process… I mean, I wouldn’t call it “cute”, but the way I see it, if you fuck with simpletons, you’re gonna pick up a stain or two.
On the other hand, if she’s a sloppy pig of a kisser who can’t keep her messy mouth under control, or she’s one of these hyperactive dipshits who spits when she talks, or she’s a slack-jawed, dimwitted mouth-breather who really shouldn’t have been standing so close to me in the first place… gross.
