Kihasználom azt a tényt, hogy a szüleim elmentek, és megbaszom a mostohatestvéremet

One afternoon my parents went out and left me in charge of my stupid stepbrother, I was very horny and my stepbrother was starting to awaken a sexual feeling in me, every time I saw him I got excited to such an extent that I had to go masturbate and now at last that we are alone it is time to take advantage and fuck him
