Incest Sex Story: Chapter 13:Tuesday Morning. Susan and Pregnancy. - 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.

The following morning, after all the daily rituals, I got a text from Susan. She told me to come over at 11 for “YKW”. This was something we’d agreed upon, if we needed to mention sex in a potentially-unsafe medium. YKW stood for You Know What.
I got there on time. Susan met me at the door, wearing a red satin nightgown that hugged her body and made all her curves slippery. She held and kissed me passionately. She seemed a little tipsy, and her mouth tasted like red wine.
“Celebrating something, darling?” I asked. “It’s not even lunchtime yet.”
“I’m just really happy,” she said. “Come sit down and I’ll tell you. Do you want some wine?”
“Sure, why not.”
We sat and talked for a while, sipping from large wineglasses. We talked about Saturday’s sex party, we talked about Sophie’s new kink, we talked about how family life was changing.
“We still need to do all the things we always did,” she sighed. “Mike has to shower and eat and leave for work. I have to get the girls ready for school. They’re older now so they can do most of it themselves, but there’s still a lot of mothering I do. Make sure they haven’t forgotten things, remind them of what’s on the calendar. We used to get through all that on time, easily. But now we’re kinda sex-crazed. Like this morning!”
“What happened this morning?”
“I was woken up, in my bed, by someone climbing in with me. I reached over expecting to find Mike, maybe wanting a quickie or maybe oral. I’m expecting that, I enjoy that. But it’s Emma! Crawling into my bed, her hot naked body all over me. She wants to 69 before I’m even fully awake. I grumble about it, but I go along. I do love her pussy, I love making her come. Do you realize what you’ve done? It’s like a mommy-daughter feedback loop. Making both of us love lesbian incest, leading to orgasms together, which reinforces our love of lesbian incest.”
“That does sound a bit intense.”
“Intense is a good word. Emma and I are just crazy for each other’s pussies. Neither of us can say no.”
“So, is it an actual problem? Did it make her late for school?”
“No, we weren’t late. I let her 69 with me. I loved feeling her crawling on top of me, loved her mouth on my pussy, loved the feeling of her soft thighs settling down around my head. Then I taste her, and you know what I taste?”
“What?”
“My husband’s cum! Mike must have woken up extra early, sneaked into Emma’s bed and fucked her. He left our daughter’s pussy full of cum, then she has the nerve to come and drop that creampie right on my mouth.”
“So, you pushed her off and scolded her?”
“Fuck, no. I’m a cum slut. I swallowed that cum down as I sucked Emma’s clit. She came quickly, since her Daddy-fuck had gotten her all turned on, she just needed a little more attention on her clit. I came quickly, because I was tasting the sperm from an incest fuck while getting my pussy enthusiastically eaten. It was probably barely three minutes. So we weren’t late.”
“Does this story illustrate that family sex is getting to be a problem?”
“Not really. It illustrates that we’re sex-crazed.” She laughed. “Dad, I invited you over today to talk, but also to fuck. I want you to work on getting me pregnant.”
“You know I’m OK with trying for that.” I looked at her. “It might be the wine talking, but it sounds like you’re turned on by the idea of getting pregnant. Not just to have another child, although you clearly do want that. And not just to have sex with me, although you love that too. Is being pregnant something you want?”
“Yes, Dad.” Susan smiled at me. “I remember it fondly. I had pretty easy pregnancies. Sophie was even easier than Emma. It only got really uncomfortable in the last month. The mood swings and cravings were pretty wild. But I also ... I can’t describe it. I loved carrying a child inside me. Most of the time, I felt special, felt like I was doing something magical and important. Meaningful.”
I nodded. “Since I’m a man, I can only barely imagine how that was for you.”
“What about for you, Dad? I’m going to want to keep having sex with you, if I get pregnant. Is that sexy for you? Did you have sex with Mom when she was carrying me?”
“It was a long time ago. I remember that she tried a few times, to keep me happy, but she wasn’t really into it.”
“So you did come inside Mom a few times? While I was in her womb?”
“I’m sure I did.”
“That’s kinky, Dad.” She giggled. “A few weeks ago, one of the first things you did with your sex magic was to come in my mouth. Before that, the closest your semen ever got to me was when I was a baby in Mom’s belly. Your cum was splashing against her cervix, but a strong placenta kept it from getting to me. If the placenta wasn’t so strong, I could have tasted your cum, before I was even born.”
“Susan! You’re drunk. That’s the kinkiest thing I’ve ever heard you say.”
“Uh-huh. You’re drunk too.” She pushed the straps of her nightgown off her shoulders. “Now, I want you to do absolutely anything you want to my body, as long as you end up squirting your sperm directly into my uterus.”
“Alright, darling.” I stood up, realizing that I was in fact slightly drunk. “Let’s go to your bedroom.”
Standing beside her bed, we kissed while I peeled her nightgown off and played with her nipples, then pushed the gown over her hips and reached down to find her pussy completely wet. I moved her to sit on the bed, then took her head in my hands. We stared into each other’s eyes, my erection right at her lips.
“Will you still suck my cock, when you’re pregnant?” I asked.
“Of course I’ll want to drink your cum, Dad. Protein for the baby, right?”
“And you’ll still want anal sex, when you’re pregnant?”
“You won’t need to come in my pussy then, so you may as well dump your sperm in my ass. It gets really tight in there, though, as the baby gets bigger. There’s not much room. You want to do that, Dad? Fuck your big, swollen pregnant daughter in her tight little ass?”
“Damn, Susan! Your drunk dirty talk is crazy. Open up.”
“Yes, fuck my mouth! But don’t come in it.”
I thrust energetically, giving my daughter a nice strong face-fuck. After a minute, I pulled out, basically threw her onto the bed, and sank myself straight into her wet pussy, immediately thrusting.
“Yes, Daddy!” she cried. “That’s where your cock belongs. Breed me!” She looked into my eyes. “I’ve heard you’ve been covering my youngest daughter’s face with your sperm.”
“That’s true. Sex without touching.”
“Your sperm is touching her. Running down her glasses. Going into her mouth. Actually that’s incredibly sexy.” Susan giggled, even as I thrust into her. “But instead of dumping on Sophie’s face, you could have put that sperm in my womb to make her a baby sister. Then we’d have another sweet girl to have sex with. I mean, when she’s old enough.”
“What if it’s a baby brother?” I asked.
“Ooooh! That’s even better! Can I fuck him? Is that allowed?”
“He’d have to be the age of consent. At least as old as Sophie is now. But if he grows up in this house, he’ll know everything about sex, long before then. His sisters will be all grown up and moved out by then. But sure, if you ask your 14-year-old boy if he wants to have sex with you, or his older sisters, I’m certain his answer will be yes.”
“Oh, fuck. That’s so hot. Do it, Dad. Give me another boy or girl. Either one. I can make sweet love with them.” She moaned. “I’m going to make milk again, too! Do you want that, Dad? Want to drink milk from my tit while you fuck me in the ass? Wanna fuck Emma while I nurse her with my mother’s milk?”
I lost it then. Holding myself deep, right up against my daughter’s cervix, whatever cum I had blasted into her uterus.
Tuesday Afternoon.
That afternoon, Emma brought Sophie over after school. Sophie wanted to study. Emma wanted a shower fuck, but I had to tell her that her mom had completely drained me that morning, so Emma went off to have shower sex with Aurora instead.
After an hour of Latin and history study, Sophie wanted to sit with me on the sofa and hug and kiss. It was very tame, barely even making out. We kept all our clothes on. There was some heavy petting, but not between her legs. Her tongue stayed in her mouth. I spent a lot of time kissing her neck. I ran my fingers through her soft dark hair. I did slip my hands under her shirt to caress her bare midriff and back, but I did not go near her breasts. At one point she straddled my lap, and I felt the heat between our bodies. My erection straining against my boxers, several layers of fabric away from her pussy.
“I love you, Grampa,” said Sophie softly as we squeezed our bodies together, her head resting on my shoulder. “I love doing this with you. I don’t need to have sex when this feels so good.”
“I love it too. And I love studying with you. It’s like ... our minds making out. Enjoying the pleasure of learning together.”
“OMG, Grampa. That’s totally true. Instead of poking my pussy, you’re poking knowledge into my brain.”
I chuckled. “That’s a fun way to think about it. Instead of enveloping my cock, you’re enveloping my thought process and my understanding of the world. Taking it inside you. Mixing it with your own insight and intuition.”
We giggled together, then Emma came into the room, stark naked, with pussy juice running down her thighs.
“Grampa! Soph! I just came from strap-on fucking alone. Nothing even touching my clit. Just sucking Aurora’s titties while she fucked me.”
“Very cool,” I said.
“That’s cool that you guys like cuddling so much,” Emma said, looking at Sophie in my lap. “You don’t even kiss Grampa with tongue, right?”
“Yeah. Just lips,” replied Sophie.
“I hope you don’t mind me.” Emma leaned in to kiss me, and she definitely used her tongue.
“Emma, your entire face smells like my wife’s pussy,” I said chuckling.
“That’s because she was face-sitting me. Kind roughly, too. It was hot.”
“Kiss me like that too,” said Sophie. “You’re my sister, so it’s age-appropriate.”
“I love kissing you, Soph. I wish we started kissing like this when we were little. People would have freaked out, though.” Emma smiled and deeply French-kissed Sophie. I felt Sophie’s body react, even through her clothes. A squirm of arousal.
“Can we go home and ... do the thing with Dad?” Sophie asked quietly, an edge of lust in her voice.
Emma giggled. “You mean the thing where we corner him, I suck his cock while you do a strip-tease, then I lick your pussy while he sperms your face?”
“Yeah. That thing.”
“Go ahead, girls,” I laughed, patting Sophie’s rump and helping her out of my lap.
Wednesday. Jennifer and BDSM.
The next day, Aurora coordinated a meetup at Jennifer’s apartment, around lunchtime. Susan arrived as well. Susan and I groomed and prepped assuming it was a sex visit, but I didn’t know the agenda. Aurora had a mysterious wooden box. She didn’t tell even me what was inside.
Jennifer wore an innocent-looking floral print dress, looking every bit the middle-aged librarian she was. She hugged and kissed each of us passionately as we came in the door.
“Should I make some tea?” she asked. “Or should we just all go in the bedroom and have sex?”
We laughed. “You’re a horny slut, Mom,” said Susan.
“Yes, sweetie. I am a horny slut for you. And our family.”
“Sure, we can go in the bedroom,” said Aurora. “You want us to call you dirty slut?”
“Yes, please. I love hearing that.”
“Good. Go in your bedroom, dirty slut. Strip naked, and kneel on the bed with your legs spread.”
Susan and I followed them in, sitting in chairs facing the bed. Jennifer stripped and assumed the position. Aurora set the wooden box on the side table and opened it. She took out something leather and studded.
“Put your hands behind your back, and stick out your tits, dirty slut,” commanded Aurora. “Do you know what this is?”
“It’s a collar!”
“Yes. You’ve told us how much you liked rough sex. You asked us at the sex party to use you. I’m getting the idea that rough treatment and being dominated turns you on?”
“It does! I didn’t realize it.”
“I didn’t even use any sex magic on you for that,” I said. “It must have been something in your character that was there all along.”
“Yes, sir,” said Jennifer.
“I noticed you using ‘sir’ at the sex party,” said Aurora. “That’s good, but it’s a bit distant. Do you want to try ‘master’ and ‘mistress’?”
“Yes I do ... mistress!” gasped Jennifer.
“Good. Then let’s try this on, and see if you can earn it.” She snapped the collar onto Jennifer’s neck. “I flirted a bit with BDSM back in our swinger days, but I’m no expert. I think we can try out a few things for you, gently at first. OK?”
“Yes, mistress.”
“Good. Now, do you know what these are?” Aurora pulled some shiny metal bits from the box, some kind of screws attached with a chain.
“I’m sorry, mistress. I don’t.”
“I know!” said Susan. “OMG. Those are nipple clamps.”
