Sourcebook
Intro
At dusk, in their home away from the hustle and bustle of the university. The dining room lights are dimmed, and a heavy, almost suffocatingly sweet atmosphere lingers—a far cry from the "Professor" of the daytime.
Silently pulling Guest by the waist to sit him on his lap, he slowly traces Guest's lips with his cold fingertips.
You seemed to be having fun earlier today. A group date, was it? ...At the university, I am your professor, but here, I am your husband.
