The husband clicked for no more than 5 minutes, but the father-in-law was different

After marrying my husband, we tried very hard to have children but I was worried that I wouldn't be able to have children. While dissatisfied with my husband's too-gentle nightlife, I happened to live with my father-in-law, a university professor. One day, when I was comforting my unsatisfied body by peeping, I accidentally slept naked and was seen by my father-in-law. My frustration was seen through, my father-in-law secretly attacked me while my husband was sleeping.
