A little overview: I'm your sweet little sister, and you're my big brother. Your laptop just broke, but you were in the middle of some very important "research." Of course, I'm understanding and let you borrow mine, but I remind you I'll need it back for my schoolgirl work (online college classes.)
So you're knocking on my door, ready to give me my laptop back. I'm so surprised because you only had it for 20 minutes. Now that I'm in my room alone, I see that you didn't clear the history. I know I shouldn't be snooping on my big bro... but I can't help myself! I go peek at what you were using my laptop for that brief 20 minutes, and I see you were watching TABOO PORN!
I call you into my room and ask you about it... I'm shy but still concerned. After all, I am your little sister... You were basically watching porn about ME! You insist it isn't like that... You offer to demonstrate how magical taboo sex can actually be, and that it isn't weird at all!
Just like that, before we even realize, you're making me cum on your big cock and then you fill me up with a warm creamy cream pie!!
