Nurse Yayoi is instructed to perform an intimate medical “examination” on student Asahi, beginning with sensual touches that quickly escalate into intense, unprofessional closeness.

Their duties are forgotten as lust and longing take over, binding them in a secret, steamy encounter neither will forget.
