"I think you're hard enough for the real demonstration, Daddy," said his daughter. She reached for her purse and pulled out her lipstick. "I just need to apply some lipstick first. I do this every time I give a, I mean, my lips a bit dry." She applied a thick coating of bright red lipstick. "I'm ready to take your cock in my mouth now, Daddy."
"Lipstick on the old dipstick," whispered Jason to Michael.
"I'd fix her dry lip problem with some of my especially formulated white cream, eau de Michael," whispered Michael to his friend.
"Yeah, in your case, your spunk is more like toilet water than toilette water."
"Very funny."
"Shh... Pay attention, Jason. We are doing this for your benefit, after all. Continue, then, Susan...for the sake of your beloved brother's education."
"Okay," she said making herself more comfortable on her knees by removing a small pillow from the sofa and placing it beneath and in between her thighs.
In the way she hugged that pillow between her legs with the hard edge of the fabric in close proximity to her pussy and in constant contact with her clit, she appeared like she was getting ready to get herself off while she sucked her father's cock. Watching her deft placement of the pillow, Jason wondered if she had done this before with this particular pillow while watching late night television. He watched her thighs move in and out and forward and back, as if she was a grasshopper getting ready to jump or a cricket getting ready to sing its nightly song. He could tell from the erectness of her nipples that she was already sexually stimulating herself with the secretive movement of the pillow.
"Are you sure you're comfortable, Susan? Do you want another pillow," said Jason seeing the pillow stuffed deep between her legs and knowing full well what she was doing with her leg motion.
"No, I'm quite comfortable, thank you," she said giving him a quick look and even a quicker smile.
"Now," she said looking up at and directing her conversation to her brother. "If I took Daddy's big cock in my mouth," she said stroking her father's cock. "As I did with Michael's cock and if I sucked Daddy's cock deep in my mouth while slowly stroking it and licking the length of it with my tongue and swirling my tongue around the head of his cock, then normally that would be a sexual thing. Yet, since this is a demonstration, it's not."
"So, let me see if I understand. What you are doing now by stroking his cock and maintaining his erection and giving him a blowjob later is non-sexual," said Jason playing the fool. "I mean, because this isn't for real, it's just a demonstration of a sexual thing."
"Yes silly," she said. "If this was for real, then in essence I'd be giving Daddy a hand job and a blowjob and everyone knows that's a sexual thing. God, I'd never do that, no way. I'd never jerk off or blow my father. What kind of daughter do you think I am? I'm not into incest, that's for sure. That's disgusting," she said while still slowly stroking her father's cock and looking up at her brother. "Do you understand, Jason?"
"Really? You're kidding, right? I mean, yeah, I think I do." Jason turned his head, rolled his eyes, and let out a big sigh. "I mean, I think I'm getting the idea between what's sexual and what's non-sexual by your unselfish demonstration." He winked at Michael who was trying to conceal a laugh. "It's all so very confusing."
"Maybe, you should show him what you mean, Honey," said her father a bit short of breath. "He still has a confused look on his face."
"It's not a look of confusion, Dad," he said under his breath to Michael. "It's more the look of horror. I don't know which is worse, Susan blowing you or you allowing her to blow you?"
"Shh," said Susan shooting him a dirty look. Involved in giving and receiving a blowjob, they no longer paid attention to what he was whispering about with his friend.
"Nonetheless, it's important that he understand the difference between sexual touching and non-sexual touching, which is something that I should have explained to him years ago, otherwise, once he gets out of college and gets a job, he'll have all kinds of sexual harassment lawsuits filed against him for inappropriate touching."
"Like the one your young, hot secretary filed against you, Dad for exposing yourself to her?"
"What? Oh, that. No, that was, uhm, just a case of he said, she said and the company, uhm, settled out of court for an undisclosed amount without accepting any wrongdoing."
"Then, why did they fire you?"
"Oh, no, uhm, they didn't fire me. I, uhm, resigned."
