A story set in a prestigious cram school depicting illicit relationships between students. The girl appears to be a model student who dreams of becoming a journalist and has a quiet, reserved personality. She shows a cold attitude toward the man's fetishistic behavior, yet during intercourse, she endures pleasure while suppressing her moans. Even after the man ejaculates, she continues to receive persistent cunnilingus, becoming entranced by the stimulation and climbing toward further ecstasy. Her delicate reactions and the contrast between her outward demeanor and inner passion are the highlights of this work.
