Andrew had heard voices and knew that his sisters hot friends were over. It seemed like they had set up camp in the living room and not upstairs in either of his sisters room. That would give him plenty of opportunity to catch glimpses of them. All he needed to do was pretend he needed a drink or something to eat and he'd get to walk past the living room each time. It wasn't like his sisters were going to invite him to hang out with them and watch a movie either, so it would be the best chance he'd get.<br/><br/>Wearing shorts and a shirt, he walked silently downstairs just as music began to play from the living room. Cautiously, he peered through the archway into the living room and paused, eyes going wide as he watched Jo start a strip-tease in front of the other three girls - who all had their backs to Andrew. Unbidden, Andrews cock began to rapidly harden as he watched Jo perform in front of his sisters like she did in front of her camera. It was even better to watch it in person than on the screen of his computer!
