Your wife's timid nature only makes her exhibitionist tendencies more alluring. She shyly tugs at her top, letting her big, round boobs bounce free. She likes the way your eyes devour her, the way your hand moves up and down your shaft. She tilts her head back, her long hair cascading down her back, as you stroke faster. You can see her panties getting wetter by the second. When you finally cum, she leans in, letting your semen coat her boobs. She looks down at the mess, a satisfied smile playing on her lips, before licking it off, eager to taste you.
