Introduction. Aurora.
My name is Peter McCormack, 56 years old. I spent decades as an engineer and dad, until our daughter grew up and went off to college, and my wife Jennifer and I parted ways. I was able to retire early, and married a younger woman, Aurora. You could say she’s a trophy wife. We got together when she was 26, and at 42 she still turns heads, but after a dozen years we have an emotional bond that is well beyond the physical. I still do consulting work part-time, but Aurora and I have plenty of time to travel together and enjoy life.
My daughter Susan, now 36, is married with two teenage girls of her own, and they live a short drive away, so I am frequently involved in their lives as an active Grandpa. Since Susan and her husband both work, I’ve helped raise the girls. In the early years, I babysat a lot. The oldest, Emma, at 16 just got her driver’s license, but her younger sister Sophie 14, still needs to be driven around often.
Sexually, my married life with Jennifer was ... just OK, at first. We were so busy with our careers and being parents, we rarely had time to connect sexually. Even after Susan grew up and moved out, Jennifer just wasn’t that into it. I wanted a lot more sex, she suggested we see other people. It ended up with an amicable divorce and me hooking up with Aurora, 14 years younger than me. Aurora was almost always ready to go, no hesitation to suck my cock in any situation, and she required very little warmup to enjoy fucking. Did I mention she’s also stunningly attractive? Her sexual availability didn’t decline much after some years of marriage. And, socially, she got along fine with my ex-wife and my granddaughters.
That’s how life was, until the day I found The Book. Old books are a hobby of mine. Part of my engineering salary went toward a book collection. Nothing in my collection is museum-grade, there is no incunabula or parchment, but plenty of 17th-century works, including a lot on alchemy and mysticism, a pet interest of mine. I didn’t just collect them, but was an amateur scholar as well, spending hours studying the strange vocabulary and symbols, mostly in English or Latin, but some other European languages as well.
Then, one Saturday in my study, I came across a curious phrase. It looked like Latin, but had no literal meaning in that language. It wasn’t even grammatical, it merely used the same orthography. The surrounding text ascribed sexual magical power to it, but that was a claim I’d seen before in old esoteric works of fantasy. Just for fun, I thought I’d give it a test.
“Aurora darling, can you come here?”
She came into my study from the kitchen. Wavy blond hair parted in the middle, her large breasts contained neatly in a strong bra and dark green dress, she was as pretty as ever.
“Yes, Peter?”
“I have something I want to test. A magical phrase.”
“OK.” She smiled. “You and your old magic books again.”
“To test, I’ll ask you to do something you wouldn’t normally do. Something simple.” I considered. “Get one of your tits out, and suck on the nipple?”
“Peter! I’m making lunch, I’m not in the mood for that kind of fooling around.”
“Perfect. Now. Dametun infulas tormena.”{br}
“That’s a funny phrase.” Her voice softened, and the expression on her face changed.
“OK. Now, get one of your tits out, and suck on the nipple.”
“Huh. I think I ... actually want to do that now.” She pushed the straps of her dress over her shoulders, undid her front-clasp bra, and took hold of one of her pendulous large breasts. She lifted one large nipple to her mouth, and looked me in the eyes while she sucked.
“So the magic phrase worked?” I asked, assuming that she was just playing along to be funny.
“It ... did?” she asked. “Weirdly, this actually feels kinda sexy. Standing in front of you, sucking my own tit. It’s something I’d do to turn you on, but it wouldn’t normally turn me on.”
I stood up and faced her. “Now feed me that nipple, and suck the other one.”
“Really?” She looked at me, puzzled.
“Dametun infulas tormena.”
“Oh. Yes.” She lifted the nipple to my mouth, busily sucking the other one. We stood there, in my study, her nipple swelling slightly in my mouth as we both sucked them.
“This is turning me on,” I said.
“Me too, for some reason,” she said.
“Maybe the magic phrase actually works on you.”
“Maybe it does.” She pondered. “I know it’s just Saturday morning and I’m in the middle of making lunch, but ... can we go to bed?”
“Excellent idea.”
We went to the next room, our queen-sized bed, pulled back the covers and pulled off our clothes. She sat naked on the edge of the bed as I put my hard cock in her mouth. She sucked with more than normal enthusiasm, then lay back on the bed and spread her legs.
“Should we ... get you ready? Fingers, my tongue?” I asked, looking at her large, neatly-trimmed pussy.
“Not now. I need you inside me. Wow, what’s come over me?”
I climbed on and pushed myself into her. “Maybe it’s me. Maybe I should come all over you.”
“Very funny. Just fuck me.”
We enjoyed a few minutes of lovely missionary position. She was really into it, and her excitement was contagious.
“I want to try things,” I said. “How about I pull out of your pussy and fuck your mouth for a bit?”
“You know that’s not my favorite,” she said. “You’re all wet with the taste of me, and when you’re straddling me, you usually do it too hard.”
“I’ll be careful. Dametun infulas tormena.”
She stared at me in surprise. “I ... kinda want ... Jesus, just come up and fuck my face, OK?”
I moved up, grabbed her head, and pushed myself into her open mouth. She did her best to suck as I vigorously fucked. This was fun, but more than the sexual sensation was the astonishing fact that this one weird trick, a phrase from an obscure book, seemed to be actually working. I pulled out and sat down on the bed next to her.
“Let’s see if this phrase has any limits.”
“What ... what will you do with me? What if I don’t like it?”
“The phrase seems to get you to do things, that’s true, but it also seems to make you want and enjoy them. So whatever I suggest, I guess you’ll like it. That’s good, because as my loving wife and life partner, I don’t want you to do anything you don’t like.”
“Oh. I guess so. Yeah, you love me. So, what are you going to do and ... make me like it?”
“How about anal sex?”
“You know we tried that years ago. A few times. I wasn’t into it.”
“Mm-hmmm. Anal sex. Dametun infulas tormena.”
“Oh. My. God.” She stared at me. “I ... suddenly want you in my ass. How ... how are we going to do that?”
“Let’s get you ready. Get one of your sex toys, use plenty of lube, and practice for a while.”
“Wow. OK. Yes.” She rolled toward the edge of the bed, opened the sex-stuff drawer, and pulled out what she needed. “You ... you’re going to watch me ... work this into my own butt?”
“I can help.”
“Thanks.”
We worked together with lubed fingers, stretching and playing and pushing them inside, and then lubing the toy and working it in.
“How does that feel?” I asked, as she worked the toy in and out.
“Intense. Uncomfortable. But also ... sexy.” She looked at me. “You could have just put your cock in. But instead you’re being sweet and gentle. I love you.”
“I love you too, but it’s been years since you’ve had anything there, and it’s an issue of comfort for me, too. I want you stretched and well-lubed on the inside. You look ready.” I took the toy from her and got between her legs. “Roll your hips up a bit ... there. Now, I’m going in.”
Her face showed astonishment, some discomfort, and some lust. I popped through her sphincter, sank in gradually, working in an inch at a time, pulled out to re-lube, then went back in and got myself deep.
“I ... can’t believe it, but that actually feels good in my ass,” she said.
“Good,” I said, “because I’m not going to hold back.” I started fucking, hard.
“Oh My God!” She stared at me, and then we were kissing, her tongue crazy in my mouth, as I pounded her ass. I felt her hand move down between us, rubbing her clit as I ass-fucked her.
“I’m going to try something more,” I said.
“More?! You’re fucking my ass already! Quite wonderfully, I must add.”
“Mmm-hmm. I’m going to pull out, and you’re going to suck me.”
“From my ass? Peter, that’s nasty!”
“Dametun infulas tormena.”
“OMG. OMG.” She stared at me. “I can’t believe we’re doing this.”
I pulled out, my cock pointing toward her, shiny with lube. “Go ahead, feel it with your hand. It’s mostly just lube.”
She took my slippery erection in her hand, stroking it. “Yeah, it looks clean, but it’s still going to taste like my ass. And ... it’s obvious that you think it’s sexy, so ... I want to do it. Come on, you nasty kinky fucker, put it in my mouth and let me taste my own ass.”
I moved up, put it in. We were looking each other in the eyes as she sucked. I briefly considered whether I should be doing this. Sure, I’d seen ass-to-mouth in porn, and fantasized for years about doing it with my trophy wife. And she was, in fact, enjoying it. I settled my moral compass, thrust my cock into her mouth as she sucked hard, then pulled out.
“On your hands and knees. I’m going back up your ass.”
“Yes, please!” She scrambled into position.
“And call me Daddy.”
“Oh my god. Peter, that’s fucked up. You actually have a daughter. You want me to pretend to be Susan?”
“Or you could call me Grandpa.”
“Holy shit, Peter. That’s beyond fucked up. Your own granddaughters?”
“They’re young women. 14 and 16. And... Dametun infulas tormena.”
“OMG. OK. Yes.” She smiled at me. “Please fuck my ass some more, Daddy!”
I got behind her, held her hips and resumed our hard fuck. Her buttocks shook delightfully. She moaned continuously, taking it for several minutes. I felt my own orgasm approaching.
“Are you going to come in my butt?” asked Aurora. “Daddy?”
“I might,” I said. “You are so tight and hot. Your ass is awesome.” I held myself deep inside, my cock pulsing, and let go. Drained, I collapsed on the bed next to her. We cuddled through the afterglow.
“That was insane,” she said quietly.
“I agree. Also, it was awesome. There is no other explanation. The magic phrase works.” I rested my hand on her sweaty, naked body. “I wonder if it works on other people?”
“Maybe it only works on me,” she suggested, “Because we love each other?”
“Maybe. Clearly, I need to test it on other people.”
She smiled at me. “You horndog. You know I’m not possessive that way, but seriously ... who would you test it on?”
I thought. “Maybe the neighbor, Kimberley?”
“Good choice. She already knows us, and you’ve probably lusted after her for years. She’s half your age.”
“I have noticed her, that’s true.” I laughed. “I can try the phrase on her, and if it doesn’t work, she’ll just brush it off as me being the weird old neighbor again.” I sniffed. “But first, we need a shower, because of where my cock’s been.”
“And I need to brush my teeth, so my mouth doesn’t smell like my ass.”
“Yes. And we should have lunch, too.”
She giggled, and we went to shower together, and had lunch.
The Neighbor. A Test.
“Peter and Aurora! Come in,” said Kimberley when we went to her door. “Make yourself comfortable. It’s only the afternoon, but do you want a drink?”
Kimberly was 28, short dark hair, cute face, a trim body, worked as a bartender in town. She was friendly, and we had been to each other’s houses a few times socially.
“Sure,” I said.
“Surprise me,” added Aurora.
We sat on the sofa as Kimberley mixed us two attractive, strong cocktails. We sipped and she sat down across from us.
“So what brings you guys by today?” she asked.
“I’ve been practicing magic,” I said somewhat honestly. “And I wanted to see if it worked on you.”
“Do you want to magically pay my mortgage?” she joked. “That’s the kind of magic I need right now.”
“Actually, I might do that,” I said. “If you want to play along with this silly magic thing I’m doing.”
“OK, you have my attention.”
“Great. Now, say NO to the following suggestion. Do you want to flash me your tits?”
Kimberley laughed. “NO. No, Peter, I do not want to flash you my tits. I know you’ve been ogling me for a long time, but I’m not available for cheap thrills, you horny old goat.”
“OK. Show me your tits. Dametun infulas tormena.”
The change was dramatic. There was a look of surprise on her face. Slowly, Kimberley’s hands went to her shirt, pulling it over her head.
“I ... don’t know why, but suddenly I actually do ... want to show you my tits.”
She unsnapped her bra. Her breasts were spectacular, modestly sized, perfectly perky, small nipples.
“Those are lovely,” said Aurora.
“Beautiful tits,” I agreed. “Do you understand why you showed them to me?”
“Um ... you said something? And then I suddenly realized that I wanted to.” She smiled. “It’s actually even turning me on a little, just having you guys staring at my tits like this.”
“That’s it. That’s the magic.”
“Oh.” She smiled. “I guess it works!”
“You’re straight, right?” I asked. “You’re into men?”
“Yeah. I mean, I’ve been known to make out with girls when I’m drunk. But I only date guys.”
“OK, I figure you know what to do with a cock. Come give me a blow job.”
She laughed. “Hell no. Just because I’m a little turned on doesn’t mean...”
“Dametun infulas tormena.”
