I work in a cafe, and we have these lids for our hot cups. In case it's hard to see, the lid ramps downward into the cup and there's a cut into the lowered rim that lets the drink through. One of the girls I work with is tiny and adorable, and it's not hard to see why she's tiny; she always complains about feeling tired and sick, I ask what she ate today, she responds i.e. "two chicken tenders," then I chastise her until she eats something and magically she feels better. In this case I got her to eat a sandwich, then a lady ordered a decaf mocha: she went scooting by on some towels (she'd used too much water in the mop) to grab the cup and headed toward the espresso machine but had only heard the "mocha" part; at the last second I realize the mistake, take the drink back from the customer, we make her a new one. Cleaning up, the girl picks up the "wrong" mocha, says "I think I'm starting to feel better now!", holds the rim of the cup to her lower lip, and sticks her tongue all the way down through the opening in the lid to lick the top of the mocha. Here in real life it was just hilarious and minorly lewd; if only life worked by hentai logic.
