While he remains focused on his book, she uses her hands to circle and pinch his sensitive nipples through his shirt, causing him to shiver and squirm with unexpected tension. What begins as a quiet afternoon of tea and books quickly turns into a game of sensory teasing, testing his composure as she playfully messes with him.
