It had proved to be a disastrous marriage even though Mark was polite, non-violent, and a good earner (he had been a senior corporate executive before...taken up the university position). But his interest in sex was almost non-existent and his boring conservatism drew Lauren to the point of screaming boredom, yet she stayed with him for the sake of Julia. Julia was now 23 and no longer a c***d but inertia and habit kept the marriage together.It was a Friday morning on a lovely warm Spring day.. Gone was the boring uniformed school girl and as soon as I got out of that uniform I was going to be a liberated girl.I got my new life of to a gentle start by going to the toilet on the train and taking my bra and knickers off. The knickers looked like I’d blown my nose in them and my pussy was tingling something rotten. I left the underwear in the trash bin.F.Y.I. I was on the train because I managed to escape from school a couple of days early and I wanted to surprise daddy. Okay, it was a 3. I put on one of Nick's long T-shirts like I always did just to have some part of him close to me. I laid down on my bed as I listened to some relaxing music from Bjork.I was beginning to doze off when I heard a soft knock on my door. I quickly woke up from my little daze and looked at the clock. It was already almost midnight. I figured it was my mother telling me to turn my music down a bit.As I opened the door I saw Eric standing there looking at me. He gave me a mischievous smile."Are you. . PLEASE." as tears started to stream down her face. Running short of air in her confines she pleaded "Billy, I can't breath."Billy looked down and seeing a six-inch plug in the side of the barrel, unscrewed it. Fresh air flooded the interior allowing Martha to breath. She lay still as she filled her lungs with air. Meanwhile, Billy stepped up to Martha's unclothed ass and placed his right hand on her bare cheeks. He started rubbing first one and then the other in turn. Moving back to the first.
