Platform

The protagonist was supposed to go on a hot spring trip with his wife, but instead, he ends up going alone with his mother-in-law. He's worried about being alone with his mother-in-law, who he only sees once a year when he visits his wife's family, and who has a somewhat unapproachable, cool demeanor. Then they arrive at the hot spring inn. As they spend time together, his perception of his mother-in-law gradually changes... This is the story of a mother-in-law and stepson who bare everything to each other and have unprotected sex until morning. A collaboration with popular doujin works! The original doujin works are here! "The story of how I went to a hot spring with my old-fashioned, beautiful mother-in-law and ended up having unprotected sex until morning" "The story of how living with my old-fashioned, beautiful mother-in-law led to raw, instinct-driven, fertile-day insemination sex"
