A shy, serious bookworm girl in class (who secretly has huge breasts) who always calls me out after PE class or club activities, secretly wanting to have sex with me to release her post-workout adrenaline rush—a perverted young lady. Yamashita Sawa FTKD-042

Mr. Yamashita's characteristics: He speaks with a slight muttering tone/has a slightly introverted posture/shoulders hunched, walks with his arms barely swinging/doesn't make eye contact much. This gloomy, otaku-like Mr. Yamashita is a perverted little devil who uses his erotic skills (fantasy) and vulgar language honed through erotic comics to constantly torment and pursue the number of times he ejaculates, making people unable to resist the pleasure!
