At a hospital or dentist where a woman with large breasts that can be seen through her clothes works, a man who unconsciously gets an erection on her chest during treatment. When you show them that erection... At first, I look away, but from the excitement of witnessing the guilt and erection Ji-Po, such as "Because of my chest ...", I will start serving as a man's mercy. Eventually it catches fire and accepts without refusing to SEX.
