However, her husband handles her sensitive nipples carelessly, gradually fueling her dissatisfaction and desire to cheat. "For example, whenever we have a marital argument and things get awkward, he starts touching my nipples, and while I'm all weak and turned on, he just smooths everything over. He only touches my body in situations like that..." Amid this ongoing frustration, she yearns for a partner who will treat her more gently, lewdly, and thoroughly adore her. Witness the explosive debut of her hyper-sensitive, pleasure-driven body as she orgasms repeatedly beyond her physical limits.
