I thought my stepsister, a popular girl at school, wouldn't read erotic manga! But she's actually a huge otaku for it! Seeing my erotic manga, she gets super excited, and when I suddenly start fondling her breasts like in the comics, she blushes and gets even more worked up! She shows off her masochistic side, accepting raw penetration with a smile! From then on, she becomes my obedient sex slave, doing whatever I say! Of course, she loves erotic manga-style acts, so my introverted otaku desires are completely fulfilled, leading to a satisfying sex life!
