My Wife Might Be a Hentai.

Synopsis

Although I was a high school student, I married my childhood friend for a certain reason. It's not like I love her or anything like that, I even considered breaking up with her. However, we got married... Since we're always together and get along fairly well, I said, "How about we get married?" "Sure. If all goes well, we don't even have to get a divorce." This is how the newly-wed life began. At first, it felt a little strange, but it wasn't so bad... "Here, say ahh! Ehe, is it delicious?" Isn't it great to live a lovely life with your wife who spoils you so much? (Source: Kakuyomu, translated)
