Living at home, I'm a pathetic guy with a brash younger sister who just started working. One day, she came back from a company drinking party completely wasted! I made fun of her sloppy appearance, which was different from usual, and then she flashed me! Panty shot too! It was awkward... but my dick was rock hard! By the time I realized it, I had already inserted and ejaculated inside her! But the next morning, my sister didn't remember having sex with me at all!? Does this mean that if I get her drunk, we can have sex without her finding out…?
