Since their honeymoon, Ayane and her husband haven't had the chance to travel together. Taking advantage of this holiday, they decided to visit a hot spring in a rural area. When they arrived at the inn, they discovered that the rooms were separated by just a thin door, allowing easy access to the next room. The person staying next door was a black American man. Being an English teacher, Ayane happily chatted with him. He also had gestures like hugging and kissing Ayane, which made her husband jealous. Things went too far when, after they had all been drinking, the black man accidentally revealed his penis, and Ayane was astonished by its enormous size. He then unzipped her husband’s pants to compare sizes. This truly angered her husband. He grumbled all night, which made Ayane upset and say some harsh words. Seeing this, her husband became even more enraged and left alone. Ayane then went next door to confide in the black man. He hugged her and comforted her, but the big hard cock kept thrusting into her, making Ayane unable to hold back touching it. Knowing that Ayane also wanted to, he immediately asked her to hold it to her heart's content. And once it started, the two couldn't stop. During their time here, the two of them constantly fucked each other over and over again. The husband also came back and asked her for forgiveness. But he also quickly despairs when he sees his beloved wife conceiving that wretched black name...
