Recently suffering from shoulder pain, Kanae quietly mentioned to her daughter, Junko, "My stiff shoulders are really bothering me." Hearing this, Junko's husband, Toshio, planned a two-night, three-day hot spring trip. Upon arriving at the inn, Kanae soaked in the hot springs with Junko and felt deeply touched by Toshio's thoughtful gesture. That evening, Toshio offered her a massage, which she happily accepted. His skilled hands, honed from years working in caregiving, sent shivers of pleasure through her body. However, just minutes later, an unexpected turn of events left her completely stunned.
