Keiko (temporary name) is 45 years old and has been married for three years. Since childhood, she worked at the okonomiyaki restaurant run by her parents, continuing to live with them. Later, she married a regular customer and gave birth to a child. Though she once enjoyed happy days, her husband died in an accident, leaving her a widow after only three years. To support her family, she began working at a snack bar and threw herself into labor, eventually reaching the age of 45. Now, she runs the family business single-handedly. Amid her daily grind, she finds herself sexually aroused by the college students working part-time at the shop, feeling that if she doesn't relieve her pent-up desires, she might succumb to temptation. Wanting to reclaim her identity as a woman, she hungrily laps at a man's cock, sucking and stroking it with her mouth before taking it in. In that moment, overwhelmed by pleasure far greater than mere fondling, she writhes and cries out. On a private hot spring trip, they unleash their passions on each other's bodies, drowning in ecstasy.
