SSIS-541: Yua Mikami has been a nurse for 4 years and is engaged to marry a doctor from the same hospital.  Things are going very well for her until the day she meets again with her scummy ex-boyfriend, Sawano, now a patient in the hospital.  She is happy now and doesn’t want to relive the past, but the ex-boyfriend thinks otherwise and forces her into an adulterous relationship in the hospital bed, no less.  She hates him so much but becomes addicted to his big cock, irremediably.
