The day had truly begun.John entered the kitchen to the smell of pancakes, his favorite. His sisters were both already sitting at the table, so he dec...ided to help his mother finish the scrambled eggs. "Last day of freedom," she said. "You all doing anything fun?" he and his sisters all answered with varying form of "no" or "not really." "Well what ever you do, don't forget that we're having the party at your dad's house tonight. John, Summer, & Autumn are all turning 18 today. It'll be fun for. Most will lay there and let you fuck them, or, if they are getting close to cumming, get you to go hard and fast until they cum.

She is an experienced, or an exceptionally well trained sex goddess, I was learning. The two of us worked at fucking for about ten minutes before she said, “How many do you think you can. "You can't be serious, David" I am and I would like you to talk to my Mom tomorrow after dinner about it. I want you to hear her perspective, because that is something I will insist is part of our marriage". "I know this is different than what is socially acceptable today, but with divorce tearing people apart, I think this is a better way." "Talk to my Mom....please?, and think about it". My Dad always makes sure that my Mom understands and most of the time she is the one to ask for it, when. I didn't have too many nice clothes, neither of us did, we'd left the children's home just two days previously and all we had was a hundred pounds each and a weekly benefit cheque to look forward to.I'm sure that the staff there knew we were lovers, but what the hell did they expect when they make siblings share a bedroom for fourteen years? Our parents had been killed in a car crash when we were just two years old and none of the few relatives we had were able to rear twins, so rather than see.
