HUNTC-205 My step-sister, who is a top-class girl at school, doesn't read erotic comics! Or so I thought... But at home, she reads all the erotic comics her geek brother writes! She gets excited by erotic comics...

My step-sister, who is a top-ranking girl at school, doesn't read erotic manga! Or so I thought... but she's actually an erotic manga otaku! My step-sister gets excited when she sees my erotic manga, and when I suddenly start squeezing her breasts like in an erotic manga, she blushes and gets really excited! She shows her masochistic face and accepts my raw insertion! From then on, she becomes my sex slave and does whatever I say! Naturally, she likes erotic manga-like acts, so my geeky desires are also super satisfied and I have a fulfilling sex life!
