That JAV

My sister-in-law, the top girl in our school, doesn't read erotic manga! But then I found out that she is actually an erotic manga geek! She gets so excited when she sees my erotic manga that she blushes and gets very excited when my sister-in-law suddenly rubs her breasts like in the manga! She showed her dominatrix face and accepted raw penetration! Since then, she's become a sex-obsessed girl who listens to everything I tell her to do! Naturally, she prefers erotic manga-like acts, so my nerdish desire is also satisfied in this fulfilling sex life!
