We were already sitting in the last bench. I told my friend to sit somewhere else. He gave me a naughty wink and left. It was a boring lecture and no ...ne was watching us.I slowly moved my feet and started caressing her silk and smoothy leg.She kept twitching for every move.I could hear her breathing increase in pace. I slowly pulled her skirt up exposing her Milky thighs. I just wanted to bury my face there. She kept her legs closed. I wedged my palm inbetween her thighs and gave her a squeeze. ‘ I loved what I saw, I saw you baby, you are the most beautiful girl I’ve ever laid my eyes on. Let’s see if I can work this doohickey.’ Sean picked up the wet vibrator, it smelled so strongly of Liz’s sweet pussy aroma. Liz laid all the way down on the bed, staring at Sean, as he bent down and kissed her long and deeply, and whispered ‘I love you baby’. Sean started kissing down Liz’s neck down to her breasts. He licked up the middle of her cleavage, and slid a hand up and over her left. Jerry listened to the submissive little voice with a real shudder of delight. How long he had longed for Julie’s pussy! How many months had he lain awake most of the night, remembering the soul-shattering smell of Julie’s pussy juice on his pillow!That night he had vowed to himself that he would have her! Have her cunt and ass and mouth! Every way it was possible for a man to take a woman, he would take his sister! It became an obsession with him but one he decided it would be safer to keep. "Close your eyes." She ordered.I did as I was told and I heard her rummaging in one of the drawers for something."OK, you can open them."I opened my eyes and saw that she was holding her school uniform from the year before: white blouse, green skirt that would reach about halfway down her thighs. She even had the knee-length socks and the shoes."I thought you were already dressed up for me." I said, slightly confused."I am. These are for you." She clarified.It dawned on me what she wanted me to.
