I was larger as a college football player but that was ten years ago and this seat would have even worse back them. I was up studying a presentation o...e of my junior people was supposed to make this week but she had an attack of appendicitis yesterday morning so I am filling in. After we take off I get out my ear buds and try to relax with some soft jazz but the strangest thing keeps happening. I keep hearing words that have no business being there. It is strange things like “his soft touch”. I realised that my sister's clothes were still laying on the floor but the boy's were gone. Before I reached the bathroom I realised that my sister's door was still wide open and I'd have to walk past it to get to the bathroom. Curiosity got the better of me as I snuck past her room. I looked in and saw my sister lying face down and naked on her bed. Her blanket lay across her lower half covering her butt but I still saw her toned legs and her bare back with her beautiful long hair covering her. I held the panties up to my noise but I wasn't quite sure what I smelled. Being the great detective that I was I dampened the crotch with a little water and held them to my noise again. This time I could identify the slight scent of semen. This was not conclusive but I now had evidence that my beautiful and loving wife might be getting fucked by another man.The realization of this left me a little confused. I felt excited that finally after six and a half years of searching I had actually found. "You need some tights anyway, to cover your hairy legs. They will help pull you in down there. I'll just go and get a few things." With that, she left the room. Unbeknownst to Alex, she did not rush down to the store, but only got as far as the head of the stairs, and the Security Office.In the gloom, Gayle could see a video image of her office, with Alex leaning against her desk, back to the camera. "Looking good?" asked Daniel, as he handed her a store carrier bag.She smiled, and just said.
