It was a well-known, respected, and inevitable perversion in our family to lust after a man who’s not your own kin. It usually hit around your seventh or eighth decade, and was a biological urge that the men in our family were encouraged to follow.
When he sat on the barstool next to me, I caught the whiff of his leather jacket permeated with cigar smoke and I couldn’t help myself but to inhale deeply. My unnaturally keen sense of smell picked up the nondescript soap he’d washed with that afternoon, the common but still dizzingly nice aftershave he’d splashed on the few areas of his neck he’d shaved, and underneath that all the complex array of hormones and phermones that regular human beings were only aware of on a subconscious level. The combination of smells awakened something in me that I’d never felt before. There it was; a stirring in my cock for the heat of a man who wasn’t my brother, father, nephew, uncle, grandfather, or cousin. Before I turned to get a good look at him I already knew I wanted him in the most carnal and lasting way.
I turned my head to see that he was sitting sideways on his stool, looking me up and down very intently. Surprisingly, he was older than me- or, more accuarately, he looked older than me. He seemed late thirties or early fourties, his skin touched by the sun over enough years to give him wrinkles and a lasting tan. Grey hairs peppered his temples under a rough buzz cut. He may not be any relative of mine- yet- but he already had the look of our clan down pat. Broad shoulders under a tight t-shirt with a rounded belly underneath, framed by leather suspenders holding up battered blue jeans hugging thick thighs.
He shrugged off his jacket in a move that was almost so corny I laughed, but I also caught my breath when saw his perfect arms. Strong, but not sculpted like a gym addict. Tufts of hair poked out of from the sleeves and collar of his t-shirt, suggesting hairy shoulders and back. He was a beast.
“Hey hot stuff, can I buy you-”
“Nah,” I interrupted. “I’ve already decided we should fuck.” I was surprised to hear myself saying it, and even more surprised to hear the hidden timbre in my voice, one of the strange gifts of our clan. It wasn’t mind control, more of a lubricant that could make certain interactions smoother and easier. He already wanted me, I wanted him, there was no need to dance around it.
The flirtatious smile that was forming on his face was fading quickly to surprise. “Hey now, we haven’t even flipped a coin for top or bottom.”
I stood, my full height looming over him. He looked almost scared now, but I could smell his phermones dancing. I leaned over and kissed his neck, then whispered in his ear.
“I’m going to pound your ass all night. Over and over. I’m going to treat you rough, and you’re going to submit to me. Like you usually do to other men, but secretly you’ve been wanting for them to do to you.”
His senses were being assailed by me. Sight, sound, smell- he was overwhelmed. Neither of us were really cognizant of leaving the seedy little leather bar, but I was relieved to remember tucking my wallet back into my pocket, so presumably our tabs were paid.
In the cool fall air, the musk that had overwhelmed us both disappated and he sort of looked at the ground awkwardly. I could tell he was still game, but his brain was re-engaging now.
“Uh- I drove. You too?”
“We’ll take my car back to my place,” I said decisively, stepping toward him.
“Uh… yeah, that’s cool. But-”
“I’ll drive you back to your car afterwards.” The hidden lower notes of my voice were reasserting themselves. I felt the overwhelming desire to have him, to own him completely and make him mine.
I managed to keep calm the entire drive, though I had to keep my window down to prevent being overwhelmed again. It was all I could do to keep him off me though; his hands were all over my body, especially my crotch, and at one point he had my zipper down and I could tell he was about to start sucking me on the freeway before I ordered him to back down.
He looked a little hurt, but obedient. I was amazed at the power I had over him so early in the game.
The instant the front door of my house was closed, we were all over each other. I could tell he rarely had to crane his neck so high to kiss another man; I tried to compensate but most of my attention was focused on ramming my tongue between his lips, pushing him back against the wall, ripping his shirt open-
My bad. I meant to pop a few buttons but forgot he was wearing a t-shirt. The sight of his thick chest hair through the torn fabric was perfect.
He expressed only the barest passing surprise, then stepped towards me again, his dark brown eyes in a frenzy of lust.
“Wait,” I commanded, holding up my palm. In the pause that followed I could hear both of us breathing heavily. We were in the throes of it now. I wasn’t sure I could really put the brakes on this instinct, but I had to try.
He fell to his knees, his eyes pleading.
“Please,” he begged. “Please, sir. Take me.”
“Yes. I will. But first- we have to have a cup of tea.”
We stared at each other for a moment, the suggestion so ridiculous that it eased the mood and we both laughed a bit.
Obediently though, he sat at the kitchen table while I boiled the kettle and made us tea. We would need the energy for what was going to happen next, and we needed the mental break so that I could explain some things to him.
I set his tea down in front of him, then stepped back and opened the kitchen window to let some more fresh air in. I took a deep breath, and it cleared my mind a bit. I was still buzzing with urges and hormones, but I was able to think again. I felt amazed that I was finally going to do this, that my time had finally come. It was happening so fast.
“I have to explain some things to you, but first I have to show you some things that might frighten you a bit.”
He looked bewildered. I could tell he was about to make some joke, probably about taking big cocks before, but then thought better of it. He could see I was serious.
I looked out the window at the moon. It was only about half full, but probably far enough along. I closed my eyes, focused, and turned to look him in the eyes.
I felt the beginings of the change; I was already well-furred but even more fur was pushing itself out through my skin. I could feel the shape of my body change, becomming longer and thicker and more animal-like. I threw back my head and growled, a sound that no regular human being could ever replicate.
He was terrified. He’d fallen out of his chair, was backing away from me on the floor. My heart broke to see what I’d done to him, but I felt it neccesary to show him.
As I returned to my normal appearance, he looked up at me, desperate for reassurance. “Sir?”
“Shhhh, it’s okay,” I said, kneeling down and putting a hand on his cheek. I was relieved to see he let me. In that moment he already looked so much younger, already vulnerable and dependent on me.
“I had to show you. I wanted you to know, and I needed you to believe me. I have some things to tell you.”
And so I told him. I told him about legends of werewolves and other cryptids and demi-humans. I told him that they were all just superstitions, but that they referred to something real that human beings had only glimpsed at. I told him about my clan, about my great-grandfather who came to the New World to start a new family, about my grandfather who turned my father who turned me, about being reborn as a new adult, with strange powers and unstoppable urges.
He listened, enrapt, barely touching his tea. He seemed torn between ignoring me and turning back to the lust I’d touched him with, or turning and running out the door.
Instead, he looked at me thoughtfully. “You want to turn me… right? Into one of your clan?”
“Sometimes it happens. The urge hits one of us, and we find a man we want to make our son.”
“Your son?” He asked, bewildered. “What does that mean?”
“When a human being becomes one of us, they are completely transformed. You will forget your previous life, you appearance will change to become more like mine, and when it’s over you will be imprinted on me as your father.”
I took a deep breath. “Listen, I won’t make you do this. I won’t decide for you. Right now we’re both under the influence of this instinct, but you can still walk out that door if you choose to.”
He chose not to.
I partly dragged him, partly carried him up the stairs. In the bedroom I tore off the rest of his clothes- I was no longer worried about things like that. My mind was in another place altogether, and so was his. The bedroom seemed instantly full of the animal musk that urged us onward. We pawed at each other, kissed, nibbled. His hands were drawn to my cock, which he unwrapped hastily. He threw himself to his knees and had his nose buried in my pubic hair in one gulp. Part of it was unquestionably practiced skill, but part of it was no doubt the lack of inhibitions that the heat had us under.
I let him suck voraciously on it for a few moments as I slipped out of the rest of my clothes, then tapped him on the shoulder. He kept going at first.
“Up,” I commanded, my voice back in that resonating tone. He was on his feet in a flash.
I picked him up brusquely and threw him onto the bed, my strength catching him off guard. I fell on top of him and resumed my rough exploration of his mouth. It felt so good to overpower him, to cover him, to do what I want with him. I felt the need to own him, fuck him, and make him my son. Nothing had ever felt so right.
The feel of his skin on my skin, with our body hair between us, was electrifying. It felt new and dizzying. I found myself grinding against him, my hard cock descending thrust by thrust towards the base of his groin.
He pulled his legs up, stretching them as far as he could, presenting his ass to me. He wanted me already, and wouldn’t say no even if I just rammed it right away without lubricant or apology.
I didn’t want to hurt him though. Not in that way.
Instead I dove down face first and impaled his hole with my tongue. He tasted amazing; still fresh from the shower, but sweet and salty from the sweat we were both working up. He gave out an exquisite moan. I devoured him like a starving man, my lips probing his hairy ass while my tongue darted in and out of his hole. I loved the way he squirmed. I grabbed his hips and pulled him onto my face.
It was so strange, and amazing, to taste the ass of a man I was unrelated to. Since my own transformation, I had only ever known the taste of relatives.
He groaned again, and I could tell he wanted me to move on to my cock, but I wanted to stretch out this event. It was so important to both of us, even if he would never remember it. I wanted to tell him afterwards about the night his daddy made him, and how I relished every second of it.
I kissed up and down the inside of his thighs, and played with my tongue around the base of his cock. Despite his pressing need to have me inside of him, I could tell he was enjoying the meandering route there.
I nipped gently on the side of his cock, barely touching it with my teeth, which earned me a surprised gasp from him. Then I descended on it with the same gusto he’d shown to me. My dad had taught me well; he was one of the most well-endowed men I knew, and refused to give up training me until he’d been able to slide his entire hard dick down my throat. I still go down on him every chance I can get; the feeling of him filling my throat like that is incredible.
As for my future son, those skills I’d picked up were being well-appreciated. I was fascinated that even the taste of his pre-cum was distinct from what I was used to.
I loomed over him again, my cock twitching in the air above his now wet hole. He played with my chest, tweaked my nipple. When that got a sharp gasp and a groan, he continued, playing with both of my nipples between his thumb and forefinger. My cock got a degree harder.
He grinned. “Fuck me, daddy.”
I grinned back. “You say that jokingly now. Soon, you’ll mean it.”
As tempted as I was to just start ramming away, I made myself practice some tenderness. I kissed him, gently this time, like a lover’s kiss, and carefully drew the head of my dick towards him. I felt the head move into him softly, and then encounter the expected resistance. Slowly, gently, I pressed on, kissing him and playing with his hair. He whimpered as the resistance gave way and I felt myself slide in. It was clear he didn’t bottom often, but in this state he wanted it so bad that he yielded fairly easily. I pushed his legs back, angling his hole to take me better.
In a few moments, I hit bottom. I was inside of him, all the way to the hilt. Our eyes locked. He nodded, silently begging me to go on.
I started gently at first, tenderly, but also taking long slowly strokes that drove him wild.
I could see the mounting frustration in his face. His big brown eyes with their wide black pupils were staring up at me, urging me to give it to him hard.
I felt something inside of me let go, like a rubber band released. I plowed into him with force. He made a sort of gasping, choking noise.
I let loose, rammed in again and again. We both wanted it; we both needed it rough and hard and mean. I could feel it escalating inside me; he was like a prey animal underneath me and I needed to do what nature required.
I bit his neck, not hard enough to hurt him or break skin, but enough to make him cry out. I looked down at him; his expression was a mix of shock and gratitude. He wanted to experience it as badly as I wanted to give it to him. I gave him another shock; I gathered my spit and sprayed it all over his face. He nodded, opened his mouth wide. I spat again, directly down his throat. The primal, animal nature of it felt amazing. I grabbed his hair and pulled it back, spat on his face again. He was soaked with spit and sweat and completely lost in the heat.
I felt another instinct come over me; I stretched my arm out and beared down on his face; without hesitation he hungrily started sniffing and nuzzling and licking my armpit. If he was under the spell of my phermones before, now he was higher than a kite.
I returned my attention to the thrusting off my hips; all of this raunchy stuff was getting me closer and closer. He could tell, too; he locked eyes with me again and nodded.
“Please, daddy, come inside me.”
I growled in agreement. I gathered him up in my arms; all of a sudden he seemed so much smaller, although the transformation hadn’t even started. I felt the size and weight and shape of him cradled inside me. He belonged to me. I was going to give him my seed, make him my kin.
I thrust harder and harder, in ecstasy. The heat of our bodies pressed together was thrilling.
And then I felt it; a point of no return, the begining of climax. The building felt unlike any orgasm I’d had before.
“Okay son,” I breathed heavily. “Ready?”
“Yes daddy. Please give it to me.”
I growled again as I let loose my cum; the orgasm, and the pumping of seed, seemed to go on forever. Some part of me realized that this was different than any orgasm I’d ever had. The cum I was pumping into him was special, meant for a specific purpose.
I collapsed next to him on to the bed, and pulled him in close. We were both panting and soaked with sweat.
“Your load,” he said between gasps- “that’s what will… transform me?”
I nodded. “Yup.”
He seemed thoughtfull for a minute, stared at the ceiling.
“How long does it take?”
I laughed. “Oh, it’ll take more than just one load. When I said we were going to be doing this all night, I meant it.”

Well, that formatted poorly. Bear with me, I’ll fix it. Edit: fixed.
