Chikan Densha Otoko Gaiden 痴漢電車男外伝～伝説へのチェイサー～

Manabu gets in a crowded train every morning. In front of him, there is Haruka, whom he is in love. He tried to approach her several times, but he couldn't do it due to his shyness.... One day, he finds a man molesting a woman. He tries to stop it, but the molester counterattacks him. What saved him was the woman, who was just being molested by the man. Her name is Natsumi and she tells Manabu that she was being molested for pleasure. "Why?" "The man just made my body like this!" Manabu tells her that he just wanted to overcome his shyness.... "I see.... You wanna change your personality, right?" Natsumi suddenly gives him a blowjob!
