Family Ties/6 months later.
It's been 6 months since your family vacation to the lake where you watched Heather take Jake's virgin load in her pussy. She made good on her promise and as soon as the family returned home Heather dumped her boyfriend of 5 months and has been Jake's one and only ever since. Considering the amount of fucking the two of them do it was no surprise to you when Heather popped up pregnant about 4 months ago. Heather, who celebrated her 17th birthday around the same time was as thrilled and Jake was in secret and the news seemed to only increase their hidden desire for one another. Thanks to a peep hole cut in a strategic location you have been lucky enough to watch their exploits.
Heather's body is developing a beautifully, sporting a gorgeous 4 month along baby bump and tits that have swollen to rival the size of your mother's. Her nipples have turned darker pink and are constantly hard, sticking out visibly no matter what she wears. You'd give anything to fuck her knocked up body just once but thus far have been unable to get anywhere but watching your luck brother fuck her through the peep hole.
Your mother and father are headed for a divorce after a fall out about 2 month after Heather announced her pregnancy. You witnessed part of the fight, not that you understood any of it and when asked your mother always changes the subject. Not that you mind. You have virtually moved into your mother's bed and have been her lover ever since the family trip, fucking her every chance you get.
Though the two of you constantly fucking went on without your father's notice, it didn't take more then a few days for your twin sister Jessie to figure out something was going on. One day after your dad left for work, you snuck into your mother's bed and were receiving the fucking of your life when Jessie walked in. At first she was upset, feeling betrayed. However, after some gentle coaxing from your mother she was more than happy to strip out of her nightie and join the two of you on the bed. It was that night your popped your beloved twin's cherry and Jessie has been active member of your sex life ever since.
It's 7 am on a Saturday, you can tell from the gentle shaking of the wall where your peep hole is at that Heather and Jake are fucking right now.
