Recently, my wife and I took in a boarder to make ends meet. Marvin is in his 20s and was looking for a convenient place to stay as he wrapped up his graduate degree.

We all settled into a nice rhythm together, but I found myself a bit fixated — not with Marvin exactly, but with the idea of him fucking my wife. I’d fantasize about them together, imagining sordid scenes during perfectly mundane activities. When Marvin reached over Kim to help her retrieve a glass from a high shelf in the kitchen, in my mind I saw him bending her over the counter while he pounded her pussy with his thick cock.

Of course, Marvin wasn’t entirely innocent. I definitely caught him eyeing Kim’s tits and ass on more than one occasion. Although Kim is arguably middle-aged, you would never know it. My honey still looks as hot as the day I met her, when we were college students ourselves. Oh yes, it was as plain as day — Marvin wanted to fuck my wife, and I was happy to let him as long as I could come along for the ride.

Kim knew Marvin was attracted to her, and she basked in the younger man’s attention. She really hammed it up, too. I would listen in, feeling my erection twitch impatiently as they exchanged playful banter across the kitchen table. It was only a matter of time before we took their exciting flirtation to the next level.

While we all sat on the couch in front of the fireplace one evening, the opportunity finally presented itself. We were sharing a bottle of wine, and Kim was clearly feeling frisky. She found plenty of excuses to touch Marvin: a brush of her fingers over his hand while she refilled his wineglass and a palm resting on his thigh as she laughed at his jokes. It all seemed perfectly innocent to the untrained eye, but I knew my wife. She was angling for more.

The tension came to a head when Kim leaned over Marvin to grab at the bottle of wine on the end table. She got real close, brushing a breast against his torso. Then she leaned so far over that she “fell” into his lap.

“Oh, how clumsy of me,” she said in a breathy voice.

I knew it was on when she made no move to settle back into her seat, and goddamn, I got excited.

Kim rolled onto her back in Marvin’s lap and looked up at him.

“Oh,” she exclaimed, squirming against what I imagined was an erection in his pants. “Someone’s excited.”

Kim rose and situated herself, so she was sitting beside Marvin again. She was done playing coy, and fuck if it didn’t turn me on.

Emboldened by Marvin’s apparent arousal, Kim reached for the zipper on his jeans and tugged it down. He didn’t resist, nor did he complain, when her delicate fingers parted his open fly and snuck inside as I watched.

“Oh, such a big boy,” she purred.

I could see her hand moving beneath the denim. She stroked his bulge while wondering aloud, “Just how far down my throat will you go, Marvin?”

Only one way to find out, I thought.

Although Kim’s hands were caressing another man, my dick didn’t seem to have received the message. It responded with enthusiasm, rising to attention as if it were my own cock tucked neatly into Kim’s fist.

I shifted in my seat, adjusting myself so my dick rested comfortably within my pants. My turn would come later. For now, I simply wanted to enjoy the show.

And what a show it was! Kim had eased Marvin’s thick dick from his pants and held it in not one, but two hands. The young man was more than well-endowed. His dick towered over the height of both Kim’s fists put together. Its large, bell-shaped head rose triumphantly above her stacked hands as if to say: “I’m in charge here.”

I didn’t doubt that. Marvin may have been the younger man between us, but he had a commanding presence. He’s the kind of guy who turns heads everywhere he goes. Knowing that he could have his pick of women only made it more satisfying to see him go wild for my wife.

Kim pumped her fists up and down Marvin’s shaft at lightning speed, causing her breasts to bounce enticingly beneath her thin camisole. But she was clearly hungry for more and leaned down to take Marvin’s dick inside her mouth, causing my cock to twitch in solidarity with our guest.

My wife is a smoldering temptress, deserving of unbridled male adoration, and that evening, the two of us were ready and willing to worship her.

Marvin’s dick gradually disappeared down her throat as she relaxed her jaw to accommodate his generous girth. When her lips bumped up against the fingers holding the base of his dick, I found myself letting out a long breath that I didn’t know I’d been holding. My wife sucked dick like a porn star, and damn, I was proud.

Kim continued like that for a while. Occasionally, she would emit a hungry hum of appreciation that made Marvin’s hips hitch. The man was clearly enjoying himself, and I was, too.

With that being said, I know my wife. She gives great head, but she loves riding dick even more. Sucking Marvin’s cock was merely a warm-up for a hard, hot fuck.

As if on cue, Kim released Marvin’s dick from between her lips with a loud, wet pop.

“Ready for a ride?” she asked.

Rendered speechless by my sexy wife, Marvin simply nodded.

Kim hopped off the couch to strip. It didn’t take long, as she hadn’t been wearing much. She shucked off her tank and shorts and revealed her lithe, lean body to us both.

She briefly stood there in all her naked glory before she backed her ass up to Marvin’s lap. She looked me in the eye, while she sat on another man’s dick and took it deep into her pussy. She was watching me watch them, and I fucking loved it.

Marvin reached around and cupped her perfectly pert tits. Without thinking, I started to egg him on by saying, “That’s right, give them a squeeze. Make sure you pinch her nipples, man. It’ll drive her fucking wild.”

The young man took my advice. He trapped Kim’s nipples between his fingers and thumbs and applied what seemed to be the perfect amount pressure — based on my wife’s moans.

That’s when Kim started getting real vocal. She arched her back and tossed her head as she released a long, loud moan.

“That’s it,” I hissed under my breath. “Fuck her good, Marvin.”

My own dick pulsed in my pants again. I observed them intensely, determined to download every moment into my mind like a film reel, so I could play it all back later.

Kim was moaning and carrying on, and she wasn’t looking at me anymore. Her eyes were shut as she tumbled into a body-quaking climax.

Marvin followed shortly after her. His fingers flexed against my wife’s breasts, holding them tightly as he hurtled into the orgasmic abyss himself.

And I sat there watching, still committing every sordid detail to memory. It was unforgettable.

When Kim opened her eyes again, she looked right at me and pinned me with her megawatt grin. She lifted herself off Marvin’s lap and moved to the seat next to him on the couch. She spread her legs wide and said to me, “Don’t leave me waiting, darling.”

More than ready to take my turn, I hurried over to dip my head between my wife’s spread thighs. Eager to eat her sloppy pussy, I sealed my lips around her hole and sucked, drawing Marvin’s thick, sticky cream into my mouth. Its rich, salty essence mingled nicely with my wife’s familiar musky flavor. Then Kim lay back, and I climbed between her legs and dipped my dick into her pussy, occupying the same space Marvin’s cock had mere moments before. Though I’d tried to lap up every bit of spunk, I definitely felt some left behind. Kim’s channel was super slick and primed for my entry. Knowing Marvin’s cream was still in my wife only elevated the experience. I was determined to add my own seed to the mix.

Kim wrapped her legs around me and locked her ankles at the small of my back, using them to pull me even closer, and I groaned her name.

Out of the corner of my eye, I spied Marvin watching us. It was his turn to watch me make Kim fall to pieces.

I pumped my hips, rapidly driving my dick into Kim’s cunt and making the couch jump from the force of my fucking. Marvin’s spicy cologne lingered on her skin, a scent that sharply contrasted with her floral perfume. That really got my motor running, and before long, I was spurting cream into my wife, letting my load join what was left of Marvin’s.

We were all thoroughly spent and retired to our respective rooms shortly afterward. But it wouldn’t be the last time I shared Kim with the handsome student, who wound up teaching me a thing or two about pleasing my wife!
