Heidi and Jeff have been best friends to my wife Tracey and me pretty much forever. Heidi and Tracey first met when they were in grade school; they were best friends all through their school days, and even went to the same college, just so they could stay together. Jeff and I met in college; we just kind of hit it off and went from there. Tracey and I started dating in college, and when we were pretty sure we were going to end up marrying each other, we introduced Heidi and Jeff to each other, knowing how much they'd like each other. When Tracey and I got married, Jeff and Heidi were the Best Man and Maid of Honor, and when they got married a few months later, we did the same for them. And we've lived in the same town ever since, so we still see a lot of each other.
In our early married years, we used to get together for occasional foursomes. It started out tamely enough -- the women started talking sex one day; they started talking about different things that we'd tried, and things we liked, and tips for doing some things better, etc., and before they were done, they'd set up an evening get-together for the four of us to have sex together. Nothing too terribly wild-and-crazy -- just each couple having sex in the same room together, where we could watch each other, and pick up tips, or ideas. Or heck, just let the other couple's lovemaking get us turned on. It was a great time, and we set up monthly sessions from then on.
But of course, I couldn't be in a room for very long, with Heidi's naked tits bouncing and jiggling, or watching Jeff's cock sliding in and out of her pussy, without wondering what it would be like to get my own hands on those lovely, luscious tits, or to slip my own meat into her. And Tracey commented more than once about how hot she got just watching Jeff's cock at work on her best friend, without actually saying that she'd like to feel it inside herself. But she didn't have to; I knew exactly what she was thinking. And I didn't suppose that Heidi and Jeff were thinking any differently, either.
So the day inevitably came when, after making love with our own spouses, we looked around the room for tacit permission to do what we all wanted to do. Tracey slid over to Jeff, and Heidi joined me, and soon we were passionately kissing and groping the opposite spouse. I watched Tracey begin stroking Jeff's cock, while he fingered her pussy and sucked her lovely C-cup tits. She was squirming and writhing at the sensations he was creating inside her with his fingers. I wasn't sure if I was jealous or not, but I was incredibly excited to see my wife enjoying the sexual attention of my best friend.
Heidi and I got into a 69 position. At first, we simply played with each other's genitals. Heidi stroked my cock, feeling its length and thickness and heft, and, I'm sure, making mental comparison with Jeff's. And I gently ran my fingers through her pubic hair, parting her labia with my finger, and tenderly rubbing her clit, causing her to moan with pleasure. It wasn't long before I had pulled her on top of myself, and we were in a full-out 69, Heidi eagerly sucking my cock while I licked and sucked on her cunt-lips and her clit.
I felt a touch on the back of my hand as I rested it on Heidi's ass while I ate her. I took my mouth off Heidi's cunt for a second to see what it was. Tracey was lying on her back next to me, with Jeff kneeling between her legs. She held his cock in her hands, with its head poised against her cunt-lips. A silent question passed between us. For a split-second, I hesitated; if we did this, there was no undoing it. But the excitement of the moment, and my own lust, were too great, and I could only nod, and whisper, "Fuck him."
Tracey smiled happily, then groaned as she fed Jeff's cock into herself. That sexy groan from my wife, and everything that went along with it, sent jolts of electricity through my body -- my wife was fucking my best friend! Jeff also groaned as he penetrated my wife for the first time, savoring the new and delightful sensations of her warm, wet cunt enveloping his throbbing erection. When he was all the way inside her, and his balls nestled against her ass, Jeff strained to press himself as deep into Tracey as he possibly could, and held himself inside her, his cockhead stirring the deepest corners of her vagina.
"Oh, Ron," Tracey groaned to me, "Look, Ron -- he's fucking me; Jeff is fucking me."
"I see it," I said. My breathing was becoming rapid and shallow, as I saw, from Tracey's facial expression, that she was clenching her cunt-muscles around Jeff's shaft, drawing another series of groans from him. "I see his cock inside you, Sweetheart, and I love it!" I reached for her hand, and we held hands, even while we were sexually engaged with our friends.
Heidi moved around to mount me herself. Raising herself up on her knees, so that her hungry opening was nudging against my cockhead, she looked at me, then over at her best friend fucking her husband on the floor, inches away. Closing her eyes, she slowly lowered herself onto my cock, which was still wet with Tracey's fluids. When her pubic bone bumped against mine, and our pubic hair became intertangled, Heidi began slowly grinding herself on my cock, creating incredible, intense sensations in my member. I groaned as I met her movements with thrusts of my own, pressing my pulsating meat up into her.
For a long while, the four of us were lost in an alternate erotic universe, my cock grinding in and out of Heidi, while Jeff pumped in and out of Tracey. Jeff is tall and red-headed, with a splash of freckles across the bridge of his nose, and on his shoulders, and I was enjoying watching his pale ass bouncing up and down as he stroked in and out of my beautiful, brunette wife. Heidi is blond, with full, round breasts that bounced delightfully as she rode me.
I closed my eyes to savor the new and unique sensations of Heidi's pussy, and the new and unique movements of her body on my cock, and how different, and yet how similar they were, to my wife's. Then, when I opened my eyes, I saw Tracey happily receiving Jeff's cock into her own depths, and I knew that she was doing the same thing -- savoring the new and unique sensations of a cock she'd never had before, and comparing it with mine.
I don't remember who started it, but when one of the four of us started to climax, it nudged all of us over the edge into an incredible, swirling, four-way, mutual orgasm. Tracey and Heidi were moaning and wailing, while Jeff and I grunted and groaned. I felt my balls tense up and then explode, sending jets of my hot, thick cum into Heidi's womb, while at the same time, Jeff's body began to twitch and shudder, and his breath came in short gasps, as he sent his seed surging into my wife.
As Jeff rolled off of Tracey, and Heidi dismounted from me, the entire scenario bordered on the surreal. All four of us lay panting, naked on the floor, utterly spent in sexual ecstasy. My cock still felt a warm glow from the insides of two women's pussies, as did Jeff's, and both women's vaginas held a soupy blend of Jeff's cum mixed with mine.
"My god!" Tracey finally gasped. "That was amazing!" We could all only agree.
Then we reconfigured ourselves again, returning to our own spouses, tacitly assuring each other that our marriages were still intact. We were well aware of the magnitude of what we'd done, and yet each of us was determined to uphold the integrity of both marriages, even if we included each other in the sexual equation. I kissed and stroked Tracey, taking and giving comfort that she was my wife, the love of my life, and our friendship with Jeff and Heidi had just gone to a new and uncharted level.
Rather than simply get dressed and go home, that night Jeff and Heidi stayed over, in our guest room. We all had a sense that we had some business to take care of, but we were too exhausted to address it until the next day.
The following morning, I came slowly awake as the rays of the morning sun began to fill our bedroom. Tracey lay naked, next to me in the bed. My penis was semi-hard with a nice case of 'morning wood', and as I rolled over to wrap my wife in an affectionate embrace, my erection nudged between her legs, sliding along her outer pussy-lips.
"Mmmmmm," she purred. "Good morning, lover."
"Good morning yourself." Lazily, I began rocking my hips, sliding my cock along her groove.
Again, Tracey purred contentedly. "That's nice," she murmured. For a few more minutes, I slid my meat against her opening like that, before she finally pulled me on top of herself. Reaching down, she directed my cock into herself, and soon we were sharing a leisurely, conjugal morning fuck together. We were in no hurry, and after the excitement of the previous evening, we were more than content to simply savor each other's bodies in relaxed, carefree mating. Tracey purred happily as I slid my erection easily in and out of her, and before long, my cock was throbbing insistently as a fresh orgasm rose within me.
I looked into my wife's eyes. Without a word passing between us, I gave myself to my orgasm with a groan of utter release. Warm, thick cum flowed freely out the end of my cock, into my wife. She groaned a happy, contented "Yesssss," as she accepted my seed within herself. Her body trembled slightly, as her own orgasm washed gently over her.
As we basked in our warm afterglow, I held Tracey tight. "I love you," I confessed, "no matter what. Last night with Heidi was fun, but you're my One and Only, the Love of My Life. Is that OK?"
Tracey nodded. "Yeah," she concurred. "It's just fine."
We got dressed and wandered out to the kitchen to get breakfast started. As we walked past the guest room, we heard Heidi and Jeff groaning through their own morning lovemaking.
Our guests arrived at the breakfast table just as I was pouring the coffee, and Tracey was filling plates with freshly scrambled eggs, and the four of us took our places around the table.
"OK," I began, "Are we all OK with what happened last night?"
"I am," nodded Heidi.
"Me too," agreed Jeff.
"No regrets?" I pressed.
