Every time he came home late from work, he would see Yu-san asking questions while she was wearing an extremely sexy outfit that revealed her cleavage, making him unable to take his eyes off that sensitive spot. He often watches adult movies and imagines that one day he will have sex with her. One time while watching a dark movie, he happened to hear her scream. He rushed to help and this time his eyes were met with her exposed breasts that weren't covered properly. He couldn't control himself. so she took the risk and proactively solicited sex. At first, she was shy and afraid that her husband would find out, but because her lustful nature could not be hidden, she responded strongly.
