As always, huge thank you to KenjiSato for editing this.
When we made our way downstairs, Sally's mother was busy in the kitchen preparing breakfast--clothed in nothing but an apron. We stood by the kitchen counter and started the usual small talk, comments on how we slept, the weather, and other basic pleasantries were passed around.
I suddenly felt a nudge from Sally. I looked over at my naked fiancée, and she said, "I can see the way you're looking at my mum, you know." I instinctively blurted out an apology before she interrupted me. "How many times? Don't apologise, it's perfectly natural; we believe sex should be a normal part of life. And you clearly want her." She pointed to the rock-hard erection I had produced.
"Well, to be honest, you look really hot in that apron, Mrs Parker," I admitted hesitantly.
She gave me a twirl, revealing the great cleavage she was packing. "Please, call me Jodie. Or mummy, if you'd prefer."
I looked to Sally to see her whispering, "You can fuck her, if you want."
To me.
I walked up behind Jodie, who was now standing over the stove. With a newfound confidence, I angled my cock and gently pressed into my soon-to-be mother-in-law.
She immediately dropped whatever she was holding, steadying herself against the counter, as I forced myself upon her.
"Mhmmmm. Your dick is so fucking big," she moaned, under her breath.
I started humping her, slowly at first, my arms finding themselves holding her tits.
"How often do you guys usually--" I began.
"Fuck? Well it varies obviously, it's just however often we want to. But I'd say I usually have at least two orgasms on any given day. Obviously more on Sundays."
"Why's that?" My fingers pinched her nipples lightly as I continued to fuck her.
"It's a surprise," Sally jumped in.
"Uhh... okay."
"Damn. You beat me to it," Natasha said disappointedly, as she and her father entered the room.
"Don't you worry, sweeetheart sweetheart, you'll get plenty of chances to fuck him," Jodie replied, her hands now planted on top of mine.
I felt a warm hand squeeze my ass momentarily, as Nat walked past me. Jodie leaned back into me, arching her back to present her round ass to me. Knowing what she wanted, I increased the speed of my thrusts substantially.
"Have you tasted his cum, yet?" Steve asked, giving his wife a peck on the cheek as she moaned.
"No, not yet, but I can wait."
"You might not have to wait long," I warned her, as my barrage of powerful thrusts continued. I took my dick out and she quickly swivelled round, dropping to her knees.
She jerked my cock fast and firm, while staring up at me expectantly.
"Mummy is such a cumslut," Natasha commented, almost casually.
In recognition, Jodie opened her mouth and forced my cock inside, instantly engulfing it in a cave of pleasure, as she sank her lips all the way to the base of my cock.
Instinctively, I grabbed her head with one hand, as ropes of cum erupted into her mouth, The pure taboo of ejaculating into the mother of the woman I had done the same to just an hour prior, sent me into an orgasmic bliss. She kept her head at the base of my cock, somehow containing its entire length, in addition to the seemingly-endless stream of cum spurting from its tip. Guzzling noises filled the room, as she swallowed my load, still not releasing me from her mouth. I panted heavily as I finally stopped cumming, and I looked around to see my fiancée, her sister, and her father staring at me in arousal.
"Yes," Jodie said to Nat, as she slowly rose to her feet, "yes, I am." She went back to preparing breakfast.
"So how are you finding it?" Jodie inquired.
"Mhm it's delicious," I replied, tucking into my eggs and bacon.
"No, I mean being sex positive. I know it's a big adjustment to make."
I looked over at Sally. For anyone else, I would never have even considered coming here, but Sally wanted me to, so I didn't even hesitate. And I was glad I didn't, this was fucking great. "I like it." I replied honestly, "It feels, right--Jesus, I never thought I'd be saying that about fucking my mother-in-law."
The family laughed, and continued eating. Over the next few hours, I learnt the family better. I learnt about what Steve's job was like as a firefighter. I learnt the frankly unbelievable story about how he and Jodie met. I learnt about how Natasha had struggled to keep a boyfriend because of the issues raised by their unorthodox lifestyle, but how she had a massive crush on the neighbour, Travis. I told them about my childhood, and all the ways in which it differed from theirs, and Sally brought up how she had recently taken up swimming. It was surprisingly normal, considering.
In fact, it was better than normal. Being naked added another layer of intimacy to our conversation, in a way I had never expected. I felt free. Open. All my feelings of embarrassment or exposure from the day before had vanished, replaced by a refreshingly unusual sense of relaxation.
In addition to the tranquility of being naked, came the freedom to look wherever I wanted to. There was something truly wonderful about the ability to have a long look at the bodies of my new family without guilt. I had initially feared that my eyes might deceive me, and offend Jodie or Nat for looking too long, but they made it very clear, that my gazes were welcome. In honesty, catching them examining my body gave me a unique thrill. I had, several times, noticed Jodie staring at my abs as I sat and talked, and had had Nat slap my ass cheekily as I walked past.
We spent most of the day inside, except about around four o'clock, when the parents briefly went to pick up some groceries, reluctantly getting dressed before they did. By this time, I sat on the couch with my fiancée snuggled up next to me, and Nat in an armchair across the room.
"Have you had him in your ass?" Natasha asked out of nowhere.
"Only a few times," Sally replied nonchalantly.
"Wow. It's so big, how was it?" her sister inquired, looking over at us.
"A lot of lube," I answered with a grin. It was so great to be able to talk about these things.
My fiancée snuggled up tighter to me before saying, "He's the biggest I've ever had. I remember the first time he fucked me."
"Tell me more," Natasha demanded, a hand slowly reaching between her legs.
"Well..." Sally began, and she must've felt my erection growing because she sat up and straddled herself on me. "It was our second date--"
"Third date," I corrected her, as I began to fondle her beautiful tits.
"Technically, our third date," she accepted, slowly moving her hips back and forth, so that my now-rock-solid cock began to rub against her clit. "So it was our third date and we went to this lovely Italian place. Oh my god, they do the best carbonara--"
"Okay, can we get to the hot bit now?" Natasha interjected impatiently, making no effort to hide the fact that she was masturbating while watching us.
My fiancée was now staring directly into my eyes, teasing my tip with her pussy as she spoke. "He dropped me off at my place, walked me to the door and kissed me goodbye." She gave me a quick kiss as if to illustrate what she had said to her sister. "I knew in that moment, that I wanted him. So, I asked him if he wanted to come in for a coffee." On the word 'in', she pushed the head of my cock into her opening, so that just the first inch was inside of her.
"Spoiler alert, I didn't have a coffee," I joked, caressing my fiancée's firm breasts, as she slowly bobbed up and down on the top of my rod.
"Well you didn't give me a chance to make one, did you?" As Sally said this, her sister stood up and moved over to us, sitting down right next to me, continuing to finger herself. "We'd barely gotten in the front door, before he was kissing me again. He picked me up, and laid me down on my kitchen table. I just remember looking up at him as he ripped my clothes off. And then..."
Sally let gravity take over, engulfing inch after inch of my cock into her pussy in one movement. She sat there for a moment, her cunt tightly wrapped around the base of my shaft, as she closed her eyes in pleasure. "Mhm that first thrust was so good, I nearly came right there and then. He started to fuck me hard," Sally said, gyrating her hips. "God, we nearly broke the table," she recalled with a laugh. I had my hands on her ass, gently guiding her, as she rocked back and forth on my cock.
"That's so fucking hot," Natasha affirmed, furiously fucking herself, as she watched her sister ride me.
