[I peeked at the class president's hidden side...] I never thought the cutest class president in the class was a perverted masochist... I found out about her sexual tendencies... Her appearance of being tied up and asking for training was lewd... She was so different from my ideal appearance that I couldn't suppress my jealousy and excitement... Bondage training, exposure and humiliation play. A bondage masochist who gets drowning in the gap between the girl and the perverted training.
