Yua is four years into nursing and newly engaged to a doctor at her hospital—then the scumbag ex she hates shows up in the emergency ward. Every time his cock gets hard, he hits the nurse call and demands that she take care of it. She despises him, but the body he trained years ago still gets wet the moment he touches her. Soon the busty nurse is waiting for the bell, sneaking into his room to ride his tireless dick and drain another load before his time runs out.
