After a traffic accident leaves him unable to move his arms and legs freely, a man is hospitalized and discovers that his assigned nurse is Ruka, the childhood friend he used to tease. Now older and even more attractive, she enjoys the reversal of power while carefully washing his body. Her panties keep flashing beneath her nurse uniform, and every touch makes him twitch. When she notices his erection, she laughs and asks whether he might still be a virgin, turning an awkward reunion into a dangerously arousing hospital stay.
