After that crazy Sunday night, Aurora and I decided to cool off for a bit, giving each of us a few days to digest what had happened. Monday, Tuesday, Wednesday. I had reconnected with my ex-wife. I had fucked my daughter. I had bent their sexual orientations enough for lesbian incest. It was a lot. We tried to focus on our chores and daily rhythms.
By Thursday morning, though, I was starting to feel horny. I started getting frisky with Aurora. She played along, sucking my cock while calling me “Daddy”, then stopped and asked smiling if I wouldn’t like to just go have sex with my real daughter? One on one, with nobody else?
I did. I called Susan.
Mike was at work. The girls were in school. Susan was home. She met me at the door, in a bathrobe. She looked serious.
“Dad. I hope you’re not here for sex.”
This surprised me. “You’ve had some time to think about it?”
“I have. And it’s too crazy. And one other thing, Dad. I’m still 36. I’m not the pill. Now, I don’t think I can get pregnant, because Mike and I haven’t used birth control in years, and it’s never happened. But there’s a remote chance. I’m not opposed to having another kid, but it probably shouldn’t be with you.”
I smiled and hugged her. “Susan, darling, that’s understandable. Maybe you just need a little magical encouragement?”
“Maybe I do. Um, you could ask me to suck you off again? I can’t get pregnant from that.”
“I want more. I want you to desire every kind of sex with me, and I want you to enjoy it. Dametun infulas tormena.”
Susan’s eyes went wide. “Oh my God, Dad. Fuck me! Take me, use me, do anything you want.”
I kissed her firmly, and she kissed back with enthusiasm. She shook the robe off her shoulders, and threw aside her bra and panties. I playfully spanked her and led her towards her bedroom, losing my own clothes as I went. She sat on the edge of the bed and squealed with surprise as I stuffed my half-hard cock in her mouth. She sucked eagerly as I grew harder and harder. Finally, I pulled out.
“This is the marital bed, where you fuck your husband?” I asked.
“Yup! And now it’s also the bed where I fuck my Daddy!”
I pushed her back on the bed, moving between her legs. I think she expected me to enter her, but instead I dove into her pussy, finding her clit to lick it. She squealed in surprise and lust. I kept going. She moaned, and in barely two minutes her body shook with her first orgasm. In a flash, I was on top of her, inside her. I just stayed there, feeling her wetness around my rock-hard erection, and we kissed.
“Oh my god,” she said. “It’s been three days, but I forgot how good it feels when you’re inside me.”
“Like I belong there.”
“Yes. Your Daddy-cock belongs inside my pussy. I love our incest-fuck.”
I started thrusting, giving it to her good and strong. We both moaned. After a bit, I pulled out and straddled her face.
“Does my Daddy-cock also belong in your mouth?”
“Yes, Daddy. But that’s more for you than for me. I love how excited you get when you fuck my mouth. And you can come in my mouth anytime you want.”
“I might.” I fucked her face for a bit, looking down, seeing the excitement in her eyes as she looked up at me, doing her best to suck as I thrust. Then I moved down again, back into missionary. After a while, I rolled her on her side, spread her legs apart, and entered her sideways, thrusting happily.
“Mike and I do this position sometimes,” she said. “He likes it.”
“I like it because I can put one hand on your butt, like this, and my other hand can grab a tit, like this, as I fuck your pussy.”
“My butt, tits, and pussy are all yours, Daddy.”
“I’m not going to come in your pussy today.”
“Are you going to pull out and use my mouth and let me drink it?”
“Nope.” I moved my hand that was on her buttock down to find her sphincter. “How about anal?”
“Oh. I don’t know, Dad. I do that rarely with Mike and don’t really enjoy it.”
“Lube?”
“It’s right there on the bedside table.”
I was able to reach for it, and lube my fingers. I played with her backdoor, working the lube in. I pressed in one finger into my daughter’s ass.
“How does that feel?” I asked.
“It’s OK. I kinda like a finger in my ass while you’re fucking me.”
I worked on her ass a bit more, lubing and re-entering. Soon I had two fingers stuffed pretty deep. It was making her pussy even tighter around my cock. I stopped thrusting with my hips, and just moved my fingers in and out of her ass.
“That’s really intense, Dad. I don’t know if I can handle more than that.”
“I’ll help you. You really desire anal sex. Dametun infulas tormena.”
Susan stared back at me. “Oh. My. God. Get that damn cock out of my pussy. I need it up my ass, now.”
“That’s the spirit! Here goes.” I pulled out, adjusted the angle, and started to press into her ass. She gasped, trying to adjust the angle of her hips to make the penetration easier. Working together, with stops to re-lube and re-enter, I finally got most of my cock in.
“Jesus, Dad. Incest wasn’t enough for you. Anal incest?”
“Yes, anal incest. You’re OK with it?”
“I’m more than OK. It’s what I want. Fuck my ass, Dad.” She moved fingers down to stroke her clit. “You might even make me come.”
“Does it ... hurt less, after I used my sex magic on you?”
“Not really. Still hurts. But now I don’t care. I love feeling you in my ass. And it’s what you want. If fucking my ass feels good to you, I want you to feel good.”
I started carefully. After a minute of gentle thrusts, I pulled out and came behind her in a spoon, then pushed myself back into her ass. This seemed to be easier for her to take. Spooning, I had one hand on her hip for leverage, rocking myself in and out.
“It doesn’t hurt as much now,” she said. “Don’t hold back. You can fuck my ass as hard and deep as you like.”
I did. The bed creaked with how hard I drove my cock up my daughter’s rectum. She was gasping with each thrust. I kissed the nape of her neck. This was great, but there was one more way I wanted to fuck her, so I pulled out and rolled her onto her back. My body was sweaty with exertion. I pushed her legs up, settling between them, my hard cock pointing toward her holes.
“Where does this belong?” I asked.
“Obviously, Daddy.” She smiled down at me, using her fingers to spread herself. “It belongs right here, all the way up my tight asshole!”
I drove in, fell forward on her, and gave her a missionary anal fuck. Now I was able to kiss her, which was why I wanted this position, to kiss my daughter’s sweet mouth as I rammed her ass.
“You, too,” I said. “I want you to come. Touch your pussy?”
“OK, Dad. You want me to masturbate while you’re up my ass?”
“Exactly.”
I couldn’t see down there, but I could feel her using both of her hands, one hand to push two fingers into her pussy, the other to rub her clit. I stopped kissing her to focus on sucking her tits and fucking her ass slowly. It took a few minutes, but they were wonderful minutes. Once she cried out in orgasm and pulled her hands back, I stopped holding back and fucked her ass hard and deep. Within a minute, I was coming.
For a long time, we just kissed through the afterglow, my cock softening inside her.
“Jesus, Dad,” she said. “Anal sex. I didn’t expect that. But I loved it.”
“I’d like to take a shower with you, to clean up.”
“I’d love that, Dad.” She smiled. “You haven’t washed my naked body since I was a little kid.”
The shower was hot and steamy, and lovely. We soaped together, we ran hands over every inch of each other’s bodies. She dropped to her knees to suck me, to “make sure I was clean”, and then asked me to wash her hair while she was down there. This was strange and oddly intimate, in a way that was somehow both sexual and not. Susan knelt in front of me, my cock filling her mouth, her tongue gently swirling around me, my fingers working shampoo gently through her long, dark hair. After that, she stood up to kiss me, and I used soapy fingers to play with her ass, again to “make sure she was clean”. When she giggled and moaned, I replaced my fingers with my cock. I knew I wouldn’t come again so soon, not at my age, but she loved it. Standing in the shower, hot water running down our bodies, my mostly-hard cock lubed with soap, thrusting deep up her ass. I didn’t come again, but to my amazement, she did, from playing with her pussy while I was in her ass. Finally, I slipped out, and we kissed some more under the water.
“That really seems to work for you,” I said.
“I think you’ve turned me into an anal slut,” she said laughing. “I can’t believe how easily I come when your cock is in there.”
“I think your husband will approve of this development.”
“I know he will!” She laughed. “When do we tell him?”
“Sometime when your daughters aren’t around. I’m not ready to handle them yet.”
“But he goes to work. Hmmm. I could tell him to leave work early today and meet us at your place?”
Welcoming Mike
Aurora and I tidied up the place. We cleaned off the messy places, put fresh flowers on the table, ran the Roomba. We showered and dressed nicely. This would be an important meeting.
Susan arrived first. She was also dressed up, and smelled really nice when she melted into my arms for a hug and deep kiss, then gave the same to Aurora. Minutes later, Mike arrived. Tall, short blonde hair, dark eyes, muscular, 38 years old. I could see how Susan liked him physically, but I also knew from 16 years that Mike was a really good person, and a great dad. I wanted to play this carefully. I liked Mike. He was family.
After small talk and drinks, we settled into the soft living room furniture.
“So my Dad stumbled across something in one of his old books,” began Susan. “It’s some kind of sex magic. And it’s had an effect on me. I’m much more sexual now. I want you to know, and I want you to be OK with it.”
“Uh, magic isn’t real, right?”
“Mike, honey. I’ve gone down on Aurora. If magic isn’t real, why am I suddenly bending my sexual orientation?”
“Wow. OK. Um. Wait.” Mike looked at me. “Are you saying you ... cast a spell on my wife?”
“Mike. Listen.” Susan stared at him. “I’m not joking. I’ve gone down on my own mom.”
There was a long pause. Mike stared at us.
“Your mom Jennifer?!”
“Yes. I went down on the pussy I was born from, and I made her come so hard. And I want to know that you’re OK with it, OK? We’re all consenting adults.”
“Yeah, but, but, um. Incest?”
“Let me help,” I said. “Mike, you might find that incest is really arousing, and your wife committing incest is the hottest thing you’ve ever heard. Dametun infulas tormena.”
Mike stared at each of us, his face a mixture of emotions. Finally, he relaxed.
“Holy shit. When you ... said whatever you said...” He smiled at us. “One minute, I’m freaked out, and Susan is saying the craziest things, and now, it makes sense. If she’s developed a sudden interest in having sex with women, and sex with her mom, then that’s just ... wild, totally sexy.”
“Oh, honey. I’m glad you understand!” Susan went to sit beside Mike, and they hugged and kissed. “You’re still my husband and the love of my life. Nothing changes, except sexually. Now, I’m kinda a slut.” She laughed. “But only a slut for family. So you know, I’ve had sex with my Dad too.”
“Many kinds of sex,” I confirmed.
“Oh. Wow. Yeah, that makes sense.” Mike looked at me, and back at Susan. “I guess it’s not cheating, if it’s family. You ... fucked your Dad?”
“I did! So, you still love me?” asked Susan. “My Dad and I even had anal sex this morning, in our bed. That’s OK?”
“Oh, sweetheart,” sighed Mike. “I will always love you. And you having ... anal ... incest is totally crazy but also extremely sexy.”
“I’m glad we’ve got that covered,” I said. “Mike, there are some serious upsides for you, in this new situation. For starters, your wife is not just more of a slut for us, but she’s more of a slut for you.”
“That’s true, sweetie,” confirmed Susan. “Casual sex, blowjobs, anal sex, whatever you want. I’m going to be more available, and I’m going to enjoy anything we do together. And you can totally have sex with my Mom, too. She’d love that.”
“I’m available too,” said Aurora, smiling. “I was already a bit of a slut, even before my husband’s sex magic. I’m sure you’ve always wanted me. As a straight guy, you’ve probably spent years thinking of me as a hot blonde with big tits that’s frustratingly unavailable?”
“Um, yeah. I have,” Mike confirmed.
“So, to prove to you that all of this is real, why don’t I strip naked, kneel in front of you, and deep-throat your cock?”
“Yes, honey,” said Susan. “You should totally do that with Aurora.”
Mike stared at us. “Uh. OK?”
Aurora dropped her clothes as she walked to them. Susan was already opening Mike’s pants. Aurora bent forward, her large breasts hanging, and kissed Mike. Susan put Mike’s hands on Aurora’s tits as they kissed, then Susan and Aurora were kissing, then Aurora dropped down and swallowed Mike’s cock.
“Oh my god,” gasped Mike. “This is really happening.”
“It is! Enjoy!” giggled Susan, then she came over to me. Mike didn’t know where to look - at Aurora’s face bobbing in his lap, or watching me and Susan undress each other. I knew Susan wanted to watch them, so once she was naked, I put her in my lap facing away from me, facing toward her husband having sex with my wife. My arms hugged Susan from behind, allowing me access to kiss the back of her neck, reaching one hand around to play with a tit, the other hand moving down to feel her wet pussy.
It slowly developed into a four-person sexual free-for-all. Mike kept asking if it was OK, and we kept reassuring him it was. Mike came down Aurora’s throat, then Aurora came over on hands and knees between our legs to eat Susan’s pussy while she sat in my lap. Mike’s erection never waned, so he came up behind Aurora and slid into her pussy. He must have been fucking her quite hard, because Aurora was the first to orgasm.
“My turn,” said Susan. “I want my husband inside me.”
