I'm also having sex with my girlfriend's mother without telling her... Yumi Anno
When his girlfriend became pregnant, Hiroshi decided to have a "shotgun marriage" and is currently registering his marriage. Her mother lives alone at her parents' house in the same city... It was her first pregnancy and birth, and I was indebted to her mother for a lot of things, so I had more opportunities to visit her parents' house on her way home from the hospital. Because she was pregnant, she had to live an ``celibate'' life, so she couldn't help but feel an immoral urge when she saw her mother's bulge swaying under the same roof...!
