The Reader (f/m, m/f)

Kate Winslet briefly tickles her lover, David Kross, while they're in bed together. You don't actually see her doing the tickling, just his reaction (he smiles and squirms) as she looks down at him. She gooses him a second time in this same scene. Later, in another scene, we see Kross kissing his way up Winslet's leg to her bare hip while she's asleep. When he kisses her bare side, her body visibly quivers, as if it tickles, and she wakes up.
