Fuufu+koukan+modorenai+yoru+married+couple+s ((free)) -

In a well-known adult graphic novel series, a couple in their tenth year of marriage agrees to a single swap with neighbors. The husband, initially excited, watches his wife laugh with the other man in a way she hasn’t laughed with him in years. That night, she returns to their bed — but she’s distant. The husband realizes: “She came back. But not all of her returned.” The story ends not with divorce, but with a quiet, unbridgeable gap at breakfast. That’s the modorenai yoru.
