A hot spring trip that was supposed to be with his wife... instead, the protagonist finds himself going alone with his mother-in-law. He was worried about being alone with her, as she gave off a cool, slightly unapproachable impression and he only saw her once a year during visits to his wife's parents' home. However, upon arriving at the hot spring inn, his perspective of her begins to change as they spend time together... This is the story of a stepmother and son-in-law who expose everything to each other and engage in raw creampie fucking until morning.
