A drama about a married woman with a healthy, pent-up body and her younger male coworker. Childless and neglected by her workaholic husband, bored Yuki takes a job at a café. At first she sees her younger colleague as a dependable little-brother type, but his confession changes everything. At work, in hotels, and at his home, they drench themselves in sweat while indulging in risky creampie sex during her fertile days. With her womb aching for him, the two continue mating like animals.
