I am a dull, single office worker surrounded by married couples in my apartment building, but I am anything but lonely. Whenever they have time, young wives neglected by their husbands come over for a quick fuck. Once word spreads, I become the building's convenient rental cock, flooded with messages asking whether my dick is free today. I travel from floor to floor for efficient quickies, and these time-saving affairs soon develop into deeply entangled relationships.
