After an accident leaves me hospitalized and under strict bed rest for three months, I discover that my nurse, Rinne Mochizuki, is stunningly beautiful. I feel guilty toward my girlfriend, but one night Rinne comes in and says it is unhealthy to let semen build up before jerking me off. Soon she is riding my immobilized body again and again, giving me an outrageously pleasurable hospital stay that I never want to end.
