My husband's younger brother - that night I became pregnant with sperm donation

My husband's brother - the night I carried his sperm
After 5 years of marriage, we realized that we could not have children with my husband's sperm, so we decided to ask his brother to donate his sperm to us...

Total number of pages: 50 (of which 25+ pages are sexual scenes)

This one is interesting,as its clear that the husband's younger brother also liked his wife, but he doesn't attempt to "steal" her as in a typical NTR doujin. The decision to ask for him to inseminate his wife also weights heavily in the husband's mind, but they do get through it.
All in all, this is surprisingly realistic, and I could see something like it happening in real life.
