If you mock your otaku little sister for only watching anime and manga, it seems like you've touched her reverse scale. Wrapped up in duct tape and photographed in an embarrassing pose... 'Did you get hard while your otaku sister played with your dick?' '(Brother) I'll buy you anything, so forgive me' 'You'll buy me anything? ...But I refuse!' 'Wow, is this what coming feels like??' 'It's the ultimate 'Yes!' The actions of my little sister, who has no interest in sex, escalate fiercely. Before I knew it, I became her pet, and eventually came inside her.
