My Girlfriend’s Husband [Mm] [Anal] [Slight Sub/Dom]

It started off innocently enough. Living in a polyamorous relationship, my girlfriend and her husband enjoyed my company outside of the bedroom, but the husband and I usually took turns sleeping with her; as open as we were with the notion of her sleeping with someone else, neither of us wanted to actively share her in bed. It was a decent arrangement that held for six or seven months before things got out of control.
Shani was a pretty free-spirited girl, and she always had a new thing for us to try, some different kind of condom or a lube that tasted like grapes. After a month of meeting her, we were regularly doing anal. Another month, and we had introduced cuffs and a soft paddle for prolonged spanking sessions. I never inquired as to what she did with Mark, her husband, but she and I had an active and engaging sex life, more and better than I had had with any of my exclusive girlfriends. Clearly, Shani was a kinkster, and she enjoyed sex as much as life itself. It was good. Really good.

Five months into the relationship, and after having moved into the couple’s home because my own landlord had kicked me out (don’t ask), Shani suggested we try prostate stimulation. At first I was hesitant; I had no problem fucking ass, but getting fucked was different. But keeping an open mind, I let her try it, and after my first mind-blowing orgasm, her mouth hoovering my cock while her two fingers wiggled around between my cheeks, I knew I was hooked. Things quickly escalated. Fingers became a plug, then a larger plug, and then finally she introduced me to Hector, her strap-on. The moment I felt her body against mine, silicone toy milking my prostate with each thrust, I knew I was sold. I loved pegging, and I was never going back.

A few weeks later, I was sitting in the kitchen, working on a report for work, when Mark called out to me:
“Hey, Henry, could you help me out for a minute?”
I frowned, but called back: “Sure. What is it?”
“Come in here for a sec.”
I rose to my feet and trudged into Mark’s bedroom. I could tell he had been working out, ’cause his torso was bare and slick with sweat, and he was panting ever so slightly. He was sitting on the bed in nothing but a pair of shorts and socks, and he smiled at me as I entered. His brown hair, unlike my own, was cropped short; I kept mine long, a final remnant of my days when I practiced Buddhism. In that sense, it was pretty clear that Mark was ten years older than me. Not that he acted it.
“What?” I tried to ignore the way his body looked, so firm and muscular. I was by no means fat, but a lot less sculpted and defined than Shani’s husband. Sometimes, I had wondered what she saw in me. My sense of humor, perhaps.
Mark grinned up at me. “Dude, I’m horny as fuck”
“Okay. So?”
“So? Help me out.”
I stared at him. “What?”
“Help me out! Come on, we’re already sharing the same woman. What’s the harm? Shani won’t mind.”

I frowned and shook my head. “I don’t know what you’ve imagined, but I’m not gay, Mark.” He laughed and got to his feet. “No? That’s not what Shani tells me.”
I froze. “What? What do you mean?”
Nonchalantly, Mark grabbed a towel and began to dry himself off. “She says you love getting fucked. That it’s all you wanna do anymore.”
“That’s not–” I felt my cheeks grow hot. “Are– are you and Shani talking about me behind my back?”
He shrugged. “Sure. She tells me all of what you guys do. Look, man, I’m not judging you. To each his own, y’know? But I gotta be at work in an hour, and I am really busting for a quick fuck.”
I opened and closed my mouth several times, trying to think of something to say. This was insane.
“Look, I’m not judging you,” he said again, and took a few steps towards me. I could see the outline of his cock, hard as rock, through his shorts. “Shani said you like getting fucked, and I figured, hey, what’s the big deal? Fake cock, real cock, it’s gotta be pretty similar, right?”

I could feel my face burning as he came closer, but for some reason I couldn’t think of anything to say. A simple ‘no’, but it refused to come. And as much as I loathed the idea, I couldn’t help but feel incredibly turned on by the blazé way he was approaching it. Mark smiled.
“Come on. We share the same house, the same woman… what’s the big deal?”
He was right in front of me now, and I felt one of his hands reach out and touch my hip. Before I knew it, he was groping my ass, a sly smirk on his face. Christ, I wanted to run, or to tell him off, but the diamond hardness in my pants told him all he needed to know.
“I– I guess.” It was all I could say. Feeling his fingers knead my ass, my body immediately began to feel warm, like it did whenever Shani was back there, prepping me for her play. I felt my breath grow shallow, and before I knew it I had walked over to the bed.

Mark followed me. Slowly, I got up on the bed on my knees, and I felt his fingers work at the hem of my jeans before he tugged them down, leaving them and my underwear pooled around my thighs. I bent forward, t-shirt sliding up as I did so, and immediately felt Mark’s fingers across my smooth skin, reaching down to knead my ass once more.
It didn’t take him long to get to the point. I heard the rustle of fabric, the crack of a bottle, and then a cool, slippery finger slid between my cheeks and began to play over my hole. He pushed, prodded and twirled his finger in little circles until he felt the muscle give way, and I let out a soft moan as the first knuckle of his digit slipped inside.
“Shit, dude, you keep it trimmed back here. Very nice!”
I wasn’t sure what to make of the compliment; was it something Shani had mentioned to him, too, how I liked to keep it smooth for her play with me? Whatever the case, the finger worked into me a few times and then retreated, and then something larger took its place. I felt his fingers pull my cheeks apart, and I wanted to protest, but the incessant pressure from his cock against me meant that all I managed to produce was a soft, pained grunt. This was not like Shani’s toy; Mark’s cock was hard, but there was a softness there, too, a pliability that made the transition from outside and inside a lot smoother. I let out a yelp as my muscle finally gave in, and he forced a good few inches into me.

“Fuck,” he moaned, and even as I was sucking in air through gritted teeth he began to move ever so slightly, his thick dick carving into me, deeper and deeper with each thrust. His hands came up to find my hips, and soon he was leveraging this hold to pull me back onto his dick. He groaned, and I felt him throb in me. Instantly, I knew that this was going to be different from when Shani took me. Mark’s movements were different, more fluid, his hips rolling into the thrust and his angle shifting ever so slightly as he adjusted himself for better depth every time he pushed in. Shani loved the teasing, loved finding ways to make me squeal and squirm; to her, fucking me was a challenge to see how far she could take me before I surrendered. Mark, on the other hand, was all business. Once he had found a good pace, he kept it, and I could feel the way he took pleasure in fucking me from the way his strokes grew harder, the way his breathing grew into a hot, heavy panting. And every time he fucked into me, the swell of his nuts slapped against me, which was new. It was skin on skin, no leather or silicone between me and the thick meat pounding me, and before I knew it, I was moaning in sync with his hips.

There was something primal in the way Mark took me; no sooner had he found his pace than he began pulling me back onto him, and after a while I felt the pain give way to pleasure. It was similar to when Shani fucked me, but different, too; the friction was a lot smoother, and Mark’s cock felt a lot more, for lack of a better word, natural. The constant *slap-slap-slap* of his hips against my ass added to the lewdness, and I could feel my own dick bouncing, hard and slick with pre-cum, underneath me. When his hands left my hips, I found that I was willingly pushing back against him, my own body picking up on the rhythm of the act.

“Ahh, fuck, you’re really enjoying this, aren’t you?”

I heard Mark laugh, and a second later his hand came down to spank me, making me yelp with pleasure and pain. He *had* been talking to Shani, then; either that, or he was just a terribly good fuck. He spanked me again and then pushed me forward, his cock pushing deeper into me as he climbed on top and put his entire weight into the strokes. I was insensate now, moaning and gasping as he hit my prostate over and over, the pressure building inside me in a way that threatened to take my breath away. Now pinned underneath him, I had no choice but to arch my back up and let my girlfriend’s husband fuck me, his cock stretching me to the limit as he opened my ass. I clutched the sheets with my fingers, feeling a bit of drool smear against my cheek. I had never cum from getting fucked alone, but the way he was laying into me, I felt like it was a real possibility. The pressure kept building as Mark wrapped his fingers into my hair, his weight enhancing every solid thrust.
And then, with a loud grunt, Mark hammered himself into me half a dozen more times and then stopped, burying himself to the hilt inside me. I felt him throb, heard his ragged breathing, and my eyes grew wide. He was cumming inside me.

Ten seconds later he pulled out and patted my butt, cool air rushing in to tickle the sudden absence of his cock. I mewled, a strange warmth filling my bowels, and he chuckled above me.

“Shit, dude, you took it like a champ! Shani needs a lot more prep before she takes it up the ass. You must really be a slut for it, huh? Hang on, don’t move…”

I felt him lean to the side, heard him reaching for something. Then a hand came down and pried my cheeks apart, and I heard the sound of a camera shutter. Mark chuckled again.
“Ah, man, nothing like a well-fucked hole. Shani’s gonna love this!”
He slapped my ass a few more times, even as I protested feebly at having my picture taken, and then, finally, climbed off of me. I lay for a bit, gasping and basking in the familiar sensation of having been fucked hard while Mark got dressed. Eventually I rolled over, my cock still rock hard, and looked up at him. He was now dressed, white collared shirt and dark slacks, and I realized that I had never got to see his cock. I had just bent over and let him take me, like a cock-hungry slut. I guess, in a sense, I was.

Mark grinned down at me, pulled on a blazer and stepped over to the door. Now that I was on my back, I could feel the thick, creamy cum beginning to leak out of me, and watching him in the doorway, fully dressed and handsome as ever, I could not help myself from reaching down and stroking myself. It was electric, pure pleasure, and no sooner had he said, “See you later, Henry,” than I was erupting all over myself, painting my neck, chest and belly with pearly white. After that I lay still, listening to my own heartbeat and feeling the gentle trickle of cum all over my body, soaking my skin and the sheets alike.
