A male student was caught on his way home from school and restrained outdoors with handcuffs. The key was tied to his dick, and it seems a pure and serious female student would come to save him! So the observation began! Eventually, the serious female student came to rescue him, but struggled to retrieve the key, causing his dick to get hard from the stimulation. She blushed and couldn't look directly at it, but was excited by the erect dick. They ended up having sex until nightfall.
