Interlude:
Ken helped Christine off the counter and led her into her bedroom and onto the bed, laying down next to her, and cuddling her close. Burying his face in her fragrant hair, while caressing her beautiful breasts. Eventually leaning down and taking her left nipple in his mouth and gently sucking on it, driving Christine wild as having her breasts played with was a major turn-on.
"Are you going to ass fuck me now son?" whispered Christine.
"Not quite yet mom. When I bend you over and slam my cock into your ass, I want to last a long time. I want to give you a world-class ass fucking. I want you screaming and begging for it. I want what you've waited for so long to be worth the wait. That means I need your help draining a couple more loads out of my cock so I can do your ass justice." said Ken.
"When we do start, we're going to start with your mouth. I ate you, it's time for my mommy whore to return the favor. You will swallow my cum. Add this rule when you rewrite your contract: You prefer to be ridden bareback, and you prefer your partners cum inside you. You can't be a cum-dump if we don't dump our cum in you!"
"I'll never spray my cum on you. I'll always pump it into you. I don't want anyone else disrespecting you by giving you facials unless you want one. The whole point of fucking a woman is to cum inside her. Pulling out is an insult to you, you're on birth control for a reason."
"Jesus!" whispered Christine. "You are your father's son. He always said he felt cheated if he wasn't allowed to cum inside his partner. He always planted his cum as deep inside me as he could, and wanted the men he lent me to to do the same."
"I'm glad to hear that my mommy slut." But let's talk about some things before I start using you again. Why didn't dad take your ass?
Christine replied: "It started as a joke. Do you remember the picture in your dad's office of the guy in the Air Force Uniform?"
"Yes," said Kevin. "His name was Tim, and he was dad's best friend, right."
"Right," said Christine. "They were closer than brothers, knowing each other since infancy. Your dad called him Timmy. Timmy knew your dad had a thing for me and used to tease your dad that I was too "High speed, low drag," for your him."
Christine went on to explain that her parents, or at least her mom, were fanatically religious, as Ken was aware of. But both Christine and her older sister, Nina, had always chafed under their mom's tight control and both sisters had, from an early age, had very strong sex drives. Christine explained that she suspected her mom's fixation on religion was because she was the same way.
Nina had left home early, and found John, always claiming that John was her gift from God as he was naturally dominant, but very caring and protective, keeping Nina happy and under control. Ken's dad was John's brother.
Nina had recognized that Christine would inevitably lose control, and disaster could result. Nina knew that Ken had a thing for Christine, but Christine wasn't interested, Christine having horrid taste in men, gravitating to the classic low-life "bad boy." Probably subconsciously defying her mom.
Nina was the one that, waiting until their mom and dad were out of town on a church trip, told Ken to march himself over to Christine's house and take her, telling him Christine would thank him. Ken did, and Christine never stopped thanking Nina and Ken for doing what had to be done. She was deliriously happy with Ken's dad. The worst day in Christine's life was when Ken Sr. died suddenly.
"Your dad routinely fucked his mom, as well as my sister Nina. He shared Nina with your Uncle John several times before he took me as his slave. When your Uncle John decided he wanted to make Nina airtight he asked your dad and Tim to be his 2nd and 3rd," explained Christine.
"You mean Grandma Annie and Aunt Nina were both fucked by dad? Has uncle John fucked you?" asked Ken
"Yes, to all those questions. I've also had girl-on-girl sex with Nina, Grandma, and Tom's mom, Alice. Your Uncle John takes care of Grandma Annie's needs to this day." replied Christine.
"Damn!" said Ken, "What a wonderful family! You know this means I get to fuck Aunt Nina and Grandma, don't you?"
Christine said: "Annie and Nina know what my fantasies are, and have made it clear they want to "entertain" you once I give into my fantasies"
