Sunday Morning. Sophie.
The following morning, Aurora and I got up early, as always, and did our morning rituals, coffee, toast, reading together. As the coffee kicked in, we talked.
Aurora asked for a step-by-step description of exactly what went down the night before, and I did my best to relay it to her.
“So now, you’ve fucked your granddaughter,” she said. “And the women in your life have pretty much all had sex with each other, too. You’re set up for anything else you want to do with your family. But there is one thing left to do, at Susan’s house. You need to bring Sophie in. If you’re going to be dropping by to fuck her mom and sister, it’s impractical to hide it from her.”
“That’s true. And you had the smart idea of instilling voyeurism in her. I’ll go over this morning, it’s still a weekend, so everyone will probably be home. Do you want to come with me?”
“You don’t need me for Sophie. Take Susan and Emma and go have a talk with her. Susan already knows about the voyeurism idea, and she’s explained it to Mike, too. But I’ll come with you to their house, because I haven’t actually had any orgasms in 48 hours, and I’m sure Mike will be home. That will be fun for me, and it’ll give you guys space to do what you need.”
We called Susan to make sure they were in fact all home, we freshened up, then drove over.
When we got there, the family was just leaving the breakfast table. Susan was in pajamas, Emma was in a sports bra with shorts. Sophie was geekier than her sister, but in appearance she was always more of a girly-girl. She wore a pale blue dress and even a little bit of makeup. Her dark-brown hair was longer, she wore prescription glasses. She was also two years younger, so there were less obvious tits and hips inside her loose-fitting dress. She was, in many ways, already a young woman - not just a girl. That was important to me, for what I was about to do.
“Hi, Grampa!” said Sophie, coming over and giving me a quick familial hug. She was awkward with most people her age, but she was always comfortable talking with me.
“I need to have a talk with you,” I said. “And your mom and sister.”
“Where should we have the talk?” asked Susan.
“In Sophie’s room,” I suggested.
“My room? Weird, OK.” Sophie led us down the hall. Their house was big enough that each girl had a room of her own. Sophie’s room was crowded, a single desk with a large monitor, a gaming chair, a bed, shelves loaded with art and science projects and stuff from her childhood, and anime figures and other geeky stuff. A large poster on the wall showed all the spacecraft of the Star Trek universe, to scale with each other.
Sophie settled into her fancy chair, we sat on the bed.
“So, Grampa, what’s the talk about?” asked Sophie.
“It’s about sex,” I began.
Emma giggled. “I know all about sex. There is the internet, you know. You guys don’t have to have the talk with me.”
“There are some things about sex which you won’t learn about on the internet,” I said. “Things about our family.”
That stopped her giggle and gave me Sophie’s full attention.
“Our family?”
“Yes. For starters, are you comfortable talking about sex with us?”
“I hope you are, sweetheart,” said Susan softly. “You can talk about anything with us. But I know some young people aren’t comfortable talking with their family about it.”
“I can talk about sex,” said Sophie, “but there’s not much to say, seeing how I haven’t had any yet. You know I’m a virgin. I’ve kissed boys, but nothing more than that.”
“Do you masturbate, Sophie?” I asked.
“I do,” said Emma supportively. “All the time.”
“I masturbate too,” said Susan.
“Yeah, I do,” said Sophie. “I guess everyone does.”
“Do you watch porn?” I asked.
“Not really. Most of it is boring or gross or just for guys. But I do read erotic fanfic.”
“OK, Sophie.” I looked her up and down, then spoke. “I think you’re going to enjoy what I’m about to tell you. You’ll discover a whole new world of things that arouse you. Things that make you want to masturbate. Things that get you off. You’re going to find that you’re totally turned on by a particular form of voyeurism, watching the members of your own family being physically intimate with each other. Dametun infulas tormena.”
“What ... what?!” Sophie stared at me. “You’re being super weird, Grampa. I’m going to be turned on by ... watching ... you guys be ... physically intimate? Like, sex? You can’t have sex, we’re all related.”
“That’s a taboo, I know,” said Susan. “Incest. But the incest taboo exists for reasons that ... aren’t really relevant to our family. Our family is special.”
“Special?!” Sophie seemed a bit distressed.
“Lemme try to explain, Soph,” said Emma. “If I make out with Grampa, we’re not going to produce any two-headed babies, right? Even if I went all the way with him. For starters, I’m on the pill.”
“Um. I guess?”
“The incest taboo does give us something, though,” said Susan. “We can break the taboo, in some harmless ways. And breaking taboos can be exciting. So, incest can be more exciting than being intimate with someone you don’t know as well.”
“Mom!” Sophie stared at her. “You’re ... you’re using logic. Which is cool. I love logic. But the conclusion still seems super weird.”
“Here, let me demonstrate,” I said. “Susan dear, please spread your legs and kiss me.”
“OK!” She opened her pajama-clad legs, offering up her face. I kissed her deeply, and put my hand between her legs.
“Oh my God,” gasped Sophie. “But Grampa is ... your dad ... you can’t ... l”
“How does it make you feel?” asked Emma. “Watching them kiss like lovers, and feel each other up?”
There was a long pause. Sophie’s mouth hung open. Finally, she spoke.
“Um. It’s turning me on. Why is it turning me on?”
“Because it’s sexy, sweetheart,” said Susan. “Now, what if I do this?” She pulled open the stretchy fabric of her pajama bottoms, took my hand, and put it inside. “Now he’s touching my pussy. I like him touching my pussy, and we are consenting adults. Nothing bad about it.”
“Oh my God. Oh my God.” Sophie was breathing hard.
“It’s OK if you want to masturbate while you watch us, Soph,” said Emma.
“Grampa?” asked Sophie, “You’re ... touching Mom?”
“I’m feeling her soft warm pussy,” I confirmed. “It feels lovely. I’m slipping a finger into her, too. She’s wet, because she’s turned on. What we’re doing is sexy.”
“Here, let me show you it’s OK,” said Emma, pushing off her shorts and pushing her panties down to her ankles, spreading her legs. “I can touch myself, which feels nice. Or I can have Grampa do it.” She tugged at my hand. I complied, reaching over between her legs, exploring, finding her slit, and pressing a finger in.
“Now I have a finger in each pussy,” I said. “Incest is cool and sexy. Dametun infulas tormena.”
“OMG. OMG.” Sophie was reaching for her dress. “OK! If you guys can be a bunch of sexual deviants, then it’s OK for me to be a deviant too!” She lifted the dress, pushed down her panties, and immediately began masturbating.
“Do you want to watch me suck Grampa’s cock?” asked Emma.
“You wouldn’t!”
“I already have. Do you want me to show you?”
“Oh, what the fuck,” gasped Sophie. “Yes. Yes, show me.”
Emma stood up, pulled off her sports bra, then turned to me and helped me out of my pants. She knelt, naked, between my legs, looking over her shoulder to make sure Sophie had a good view, then sucked my half-hard cock into her mouth.
“OMG. OMG,” gasped Sophie. “You’re really doing it. This is really happening.”
“It is, sweetie,” said Susan. “Your sister is nearly an adult now. You know she already had sex with her boyfriend. And now she’s having sex with Grampa.” She smiled. “And with me.”
“Emma ... and... . you, Mom?!” gasped Sophie.
Emma lifted her mouth. “I’m sure that fanfic erotica you like to read has lesbian and bi sex in it, doesn’t it?”
“Yeah,” admitted Sophie. “Tons.”
“So, would you like to see me go down on Mom?”
“You wouldn’t!”
“She would!” giggled Susan, pushing off her pajama bottoms. “Kiss me first, sweetie.”
I moved aside on the bed, making room for Emma and Susan to embrace, then pull off Susan’s remaining clothes. They kissed, hotly, then Emma sucked a tit and reached between Susan’s legs.
“You’re ... touching Mom’s pussy,” gasped Sophie.
“I’m going to do more than touch it!” giggled Emma, moving down, pushing her face in and starting to lick.
“OMG. OMG.” Sophie’s fingers were moving like a blur between her own legs.
“See?” said Susan. “Your sister is eating my pussy, it feels wonderful, and there’s nothing wrong with it. We’re only breaking a taboo. And breaking taboos can be hot.”
“I ... I guess so?” mumbled Sophie.
“It turns me on too,” I said. “My own daughter and granddaughter, that I’ve known their whole lives and love more than anything, having sex together and making each other feel good. That is scorching hot.” I smiled at Sophie. “I’ve got this hard cock here. Want to watch me fuck your sister?”
Sophie moaned. “Yes!”
“Yes, what? What do you want me to do?”
“Oh, God, Grampa. You’re all going to have sex on my bed? You want me to tell you how to do it? You want me to say it out loud?”
“Yes, please. Be as explicit as you want.”
“OK. OK. Mom, get up on the bed. Emma, get up there on your hands and knees and keep licking Mom’s pussy! And Grampa, get behind Emma and fuck her, doggy-style.”
“As you wish,” said Susan. We moved into position. I had entered Emma from the front, the night before, and now I admired the shape of her young hips and butt as I pushed into her pussy from behind.
“Wait!” said Sophie suddenly. “Where’s Dad? What if he walks in on us?!”
“Your Dad’s cool with it,” I said. “He’s in the other bedroom having sex with Aurora right now.”
“Oh.” Sophie smiled, and her fingers resumed moving on her clit. “I guess everyone has gone crazy. Sex crazy.” She stared at us, at my hips moving back and forth, my cock going in and out of Emma. “Um, Grampa, does it ... feel good?”
“To fuck your sister?”
“Yeah, to fuck my sister. And you fuck Mom, too, right?”
“Yes, I do. And yes, it feels wonderful. I mean, right now, your sister’s lovely little pussy feels great around my cock. But that’s only part of it. If I was fucking some random teenager, it might feel physically good, but might also feel ... hollow. You know I love all of you, have always loved you and Emma since you were bumps in your Mom’s belly. Sex with someone you love is so much better.”
Sophie stopped masturbating for a moment. “Are you going to have sex with me, too? I don’t think I’m ready.”
“Sophie, sweetheart. I know you’re not ready. You’re not going to do a single thing you don’t want to do. You can even totally ignore the fact that your family is committing incest. But it’s going to turn you on like crazy, so I don’t think you will.”
“I’m coming!” gasped Susan.
“Wow!” said Sophie, resuming her masturbation.
“I did that!” said Emma, lifting her wet face proudly. “I licked Mom to an orgasm.” She giggled. “Want to ask Mom to eat my pussy, Soph? Please. Ask her.”
“OK. Cool.” Sophie smiled. “Mom, please eat Emma’s pussy, OK?”
