Our relationship... for seven years, things have continued like this between me and my older brother. An absolute secret, something we could never tell anyone. Right in the midst of puberty, my uncontrollable desires were directed toward my younger sister Ema, and we crossed the line. This forbidden story of brother and sister is now coming to an end. Every day, I make my sister take my cock into her mouth, forcing her to suck me off, until I can't hold back any longer and go even further. As my sister submits and my lust as a brother grows ever stronger, this tale of seven painful years finally reaches its conclusion.
