Chapter 4: Plans for Emma
Incest Sex Story: Chapter 4: Plans for Emma - An mc-ish incest story, within three generations of a family. It's loving and consent-focused, as much as consent is meaningful in a story with magical persuasion. It's still fundamentally stroke, but with a bit more depth and character development than is typical for that genre.

Friday afternoon, I spent a few hours in my home office, going back over my research, reviewing the book which gave me the weirdly effective magical phrase which had transformed my life. The rest of the book was full of wild claims, weird diversions, purely fantastical material, a re-hash of alchemical tropes from other works, and some long passages purportedly by the author about his own life. He wrote of going into trances that would last for days, then feverishly writing down what he had experienced. The great majority of it was, to put it gently, nonsense.
And yet, this one phrase, one bit of this madman’s ramblings, had this dramatic effect on the women in my life.
As Aurora and I made dinner together, I tried to describe the context as well as I could. She was an intellectual of another flavor, more given to contemporary literature and world affairs of the recent century, but she knew enough of the medieval and enlightenment period mysticism that I could explain the source material in its own jargon. She had plenty of questions.
“Is there any indication this author ... a man, of course?”
“Yes, a man.”
“Any indication he knew and used this phrase himself? Used it to build a private harem in ... whenever it was?”
“The mid-17th century. And no, no evidence indicates that he knew what he had discovered. Or maybe it didn’t actually work that well for him. Maybe it’s just me?”
“Have you thought about what else you might do with this phrase? Other than turning your loved ones into uninhibited sexual partners?”
“I’ve have a lot of thoughts. Positive and negative. Negative, I could easily invite over the mayor of our town, who is absurdly rich, get her involved in some kinky sex, film the result, and blackmail her. But that’s just not me. Not to mention possibly dangerous.”
“I agree. Pretty much anything you would do to acquire money or power would risk drawing attention, or even danger. So, positive ideas?”
“I could start a sexual therapy practice. Or, more realistically, drop in as a consultant at an existing practice. Husbands and wives coming in trying to solve their sexual baggage or lack of interest in each other. They’d still have baggage, but at least they could go home charged up and horny enough they might work through it. At least, I could get them fucking like bunnies again.”
“Maybe. I’ve known people that work in that field. The problems are usually more emotional or trauma-related. Other things are blocking their sexual function. Just turbo-charging their lust, knocking aside their inhibitions...”
“Might not help? Might make things worse?”
“Yes. So, that leaves your personal uses. So far it’s me, Jennifer, Susan and Mike. Oh, and briefly our neighbor Kimberley. You’ve mentioned your granddaughters several times now. Are you having second thoughts about them?”
“Not about Emma. Susan says she’s already sexually active, and you know her. She’s outgoing, level-headed. I could take her as a sexual partner, and it would be fine.”
“That would really be something.” Aurora smiled. “Your 56-year-old cock, going into your 16-year-old granddaughter’s body?”
“I see I don’t need any sex magic to convince you.”
“No, that’s totally wild and sexy. Assuming that she’s loving it. And since I know you and your magic, I know she will.”
“True. But, keep in mind I’m not just thinking of you and me. Me fucking Emma needs to be enthusiastically supported by everyone else in the family. And I think it would be best if, eventually, she’s sexually playing with everyone.”
“I already assumed you’d put Emma and Susan together. You love the mom-daughter thing. But Emma and her sister? Emma and her dad? Emma and her grandmother?”
“Every one of those sounds hot to me,” I admitted, smiling. “Emma is going to do fine. But not Sophie. 14 is just too young, I think. Can you remember when you were a freshman in high school? Speaking for myself, I had no perspective, no clue. She’s young, but it’s less about age than emotional maturity. She’s different than her sister, in more ways than the two years that separate them. Right now, I’m not planning to put my cock anywhere in her body, until she grows up a bit. On the other hand, family sex will become impossible if we need to hide it from her.”
“So ... she’ll need to be informed and supportive, but not participate?”
“Not participate with me or her dad, at least. But in order for my magic to work on her, as we understand it right now, it needs to be tied in some way to sexuality. It needs to involve more lust, more orgasms in Sophie’s life.”
“Voyeurism?”
“My God. You’re a genius.”
“I know. I’m not just all tits and ass.” My lovely wife laughed. “To be specific, you’ll need to condition her for family voyeurism. She’ll get off on watching her family have sex. Otherwise, a general voyeurism kink could just lead her to porn or creeping on other people.”
“You’re incredible. So, what about Emma? We’re confident she’ll do fine once she’s on board, but is there a way I could gently ease her into it?”
“I’ve thought about that. You know Emma, she’s strong-willed and independent. At 16, she’s busy trying to act like an adult. It’ll be best if everything she does seems like her own idea. Let her feel like she’s in control. Maybe even ... get her turned on by giving orders. To you and Susan, probably, at first, or maybe you and me.”
“I’d like to have you there. You understand women better than I do, and especially, you understand teenage girls better. As her grandfather watching her grow up, on one level, I feel like I know Emma intimately, but she’s also growing and changing so fast, I don’t always know how to talk to her.”
“Perfect, then. Just you and me and her. Tomorrow morning?”
“Tomorrow.”
Saturday Morning. Emma.
At 16, Emma had her own mobile, but it wasn’t a smartphone. There had been a long discussion between Emma and her mom about social media apps having negative effects on teens, but her family still needed to reach her, so a flip-phone was the compromise.
That’s how I called her, early Saturday morning. She had her own car, a beat-up used Ford Escape, which she used to drive herself and Sophie to school, and with parental permission on a case-by-case basis, for social trips on weekends. She didn’t have any plans for the morning, so she told her mom where she was going, and left for our place.
As I hung up, I wondered what Susan was thinking, knowing that Emma was on her way over to my house.
Aurora met Emma at the door. They hugged - an innocent, family hug. I knew their relationship was friendly, even emotionally intimate. There were things that Emma could confide in her mom, as her parent, and there were things Emma was more comfortable telling Aurora, because she wasn’t a parent. Technically, she was a young step-grandmother, but more like an aunt to Emma. You can tell a cool aunt pretty much anything, without fear of getting in trouble for it, or a lecture.
It was a warm day, so Emma wore a blouse over a sports bra, and running shorts. Her dark brown hair - somewhere between her dark-haired mom and blondish dad - hung attractive past her shoulders. Her cute face, her hips, the swell of her tits under her top, they were perhaps average looks for a teenage girl, but incredibly beautiful to me. She was so much more than her surface appearance. I knew her bossy personality, her affection for her family, her emotional intelligence.
“Hi, Grampa!” Emma came over to where I was sitting at the dining table, gave me a quick side hug, bent in to give me a peck on my cheek, then plopped herself into a chair at the table. “Do I smell waffles?”
“You sure do, sweetie,” said Aurora, heading into the kitchen, coming back to put a waffles and a butter tray on the table. In casual teenage fashion, Emma helped herself, ignoring the butter, just munching the waffle from her hand.
“So what did you guys invite me over for this morning?” she asked, chewing her waffle.
“Actually, to talk about sex,” I said.
“I talk about sex all the time with my mom,” she said dismissively. “And Aurora too. We had The Talk years ago. I know all about it. Why, Grampa? Is there something you want to know about sex?”
I laughed. This was the Emma I knew and loved. Bossy, in control of every conversation.
“Have you ever walked in on your mom and dad?” I asked.
She paused. “Not really. I mean, they kiss a lot, and sometimes dad gropes mom when he thinks me and Sophie aren’t around. Mom tells me they still have sex sometimes. But that’s private, you know? And I wouldn’t really want to see my dad all naked like that. That would be icky.”
“So, aside from having sex with your boyfriend, you’ve never really seen other people doing it?”
“I’ve watched porn with Liam. And I know the difference between porn and real sex because we looked at a lot of dumb cumshots and orgies and stuff until we found some more realistic porn.”
“Did any of the porn turn you on?” asked Aurora.
“Kinda. I mean, not the dumb stuff. But when it looked like real people who were really having fun, that was kinda hot.”
“What if you could watch people in real life?” continued Aurora. “What if you could watch me and Peter having great sex?”
Emma paused, staring at us, briefly at a loss for words.
“Jeez! I can’t watch Grampa! He’s ... family!”
I smiled at her. This was the moment. “But you could watch us, Emma. Because we don’t mind. And it would totally turn you on, seeing family members having sex. Dametun infulas tormena.”
Emma’s waffle was finished. She paused, looking back and forth between Aurora and I. “Uh. It would? Oh. Um, yeah. I guess it would ... turn me on. But we shouldn’t do that, right? Because he’s my Grampa and ... I don’t know, that’s supposed to be wrong, isn’t it?”
“Emma,” soothed Aurora, “I know your generation understands what consent is. If consenting adults want to do something in the privacy of their own home, and nobody is hurt, then that isn’t really wrong, is it. And you’re only watching. Unless you feel you aren’t enough of an adult yet. I mean, you are 16.”
“No way!” declared Emma. “In lots of ways, I’m totally an adult.”
I looked at Emma lovingly, delighted that her own personality was playing into our hands.
“If that’s the case,” I concluded, “then you might want to follow us into the bedroom, and watch us have sex?”
“Sure. Yeah. I do.”
“Great, then, go ahead and tell us what to do.”
Emma smiled. “Grampa, Aurora, I want you guys to go to your bedroom and let me watch you get naked and fuck.” She accentuated the F-word, as if trying to shock us, or to declare herself an adult, with adult language.
“You heard the girl boss,” said Aurora, smiling. “Peter, shall we fuck?”
“Yes, my lovely wife,” I said laughing. “There’s nothing I’d rather do.”
Emma followed us into the bedroom. She grabbed a chair and pulled it up right next to the bed. Aurora and I stood, hugging and kissing, then I helped pull off her shirt and un-hook her large bra. She pushed off my clothes, then we were standing there in our underwear, and went back to kissing and hugging.
“Wow, your tits are huge,” commented Emma.
“I’ve thought of getting surgery to make them smaller,” said Aurora, “but it’s always gotten a lot of attention from boys and men.” She pushed down my boxer shorts, my erection sprang up. “And this is your Grampa’s cock. It’s a nice cock.”
“Looks pretty normal,” said Emma, trying to sound unimpressed.
“What do we do first?” I asked Emma. “Does my lovely wife suck my cock, or do I eat her pussy?”
“Grampa! If you’re a good person, you have to lick her pussy first. And I know you’re a good person.”
“Damn right he’s a good man,” agreed Aurora, helping me push off her panties and falling back onto the bed. “You heard the girl. Get busy, darling.”
I crawled naked on the bed, kissed Aurora all over, then settled down between her legs and gave her wet pussy one long lick, followed by homing in on her clit. She make a whole series of lovely gasps and moans of pleasure.
“Hell yeah.” I heard Emma’s voice, with a hint of arousal to it already. “That’s hot. Looks like Grampa knows what he’s doing.”
“I have almost four decades of experience in pussy-eating,” I said, then went back to licking, my mouth too busy to be part of the conversation.
“And 12 years of learning what I like,” agreed Aurora, between moans. “It’s OK, sweetie, if you want to masturbate while you watch us.”
“It is? OK.” I heard what must have been the sound of Emma pushing off her running shorts and panties.
I reached up and found Aurora’s large nipples with my fingers, pinching and pulling them without breaking my tongue’s contact with her clit. She moaned.
“You like that?” asked Emma. “Like that, with your nipples?”
“Only when I’m really turned on, sweetie. And it’s a lot nicer when someone else does it.”
“Liam really likes to suck on my tits, but it turns him on more than it turns me on.”
“He probably wasn’t eating your pussy at the same time.”
“Yeah. He does eventually lick my pussy really well, though. Makes me come every time. If he didn’t, there’s no way I would have any other sex with him.”
I was using two fingers to tease Aurora’s inner labia, making her whole vulva twitch, at the same time I was rhythmically licking the hood of her large clit. Like playing an instrument, it takes practice, and every woman is different.
“That’s going to make me come too fast,” gasped Aurora, pushing my head away. “Let me suck that cock now. Emma, sweetie, you can come closer if you want, get a better view.”
Aurora and I sat up. I watched Emma, naked from the waist down, moving to sit on the bed next to us. Her vulva had a patch of neatly-trimmed fur, and she wasted no time in pressing one finger into her slit.
