A night when a man sneaks into the room of a female guest who stays at a hot spring inn that every man longs for, plays with a woman who sleeps soundly as much as she likes, and ejaculates inside out. 12 women in their 60s and 7 women in their 50s and 2 women in their 40s, born in the Showa era, who want the scent of the Showa era.
