Seijirou and Yuko stared at the door, and suddenly, it opened ever so silently.
Haruka then walked in.
She was dressed in a white nightgown, her cheeks were flushed crimson, a violent contrast to the paleness of her skin and the coldness of her gaze.
Her expression was a terrifying mix of perfect, trained stoicism and deep, unavoidable embarrassment at seeing the naked form of her mother, Yuko, intertwined with the equally bare body of Seijirou.
She didn't react with a shout, or even a gasp seeing them, after all she had heard the suppressed sounds of their lovemaking through the door,the stifled gasps and rhythmic creak of the springs, and had only knocked and entered when she assumed they were done.
Yuko's eyes widened in profound shock and mortification as she scrambled instantly to cover herself, pulling the silken sheets up to her neck, stuttering in genuine, maternal distress.
