Claimed by my Sister’s Boyfriend at Thanksgiving Dinner 

I woke up sore, the sleeping bag tangled around my legs, my hole still tender and slick. The tent was empty. Stephen’s body heat was gone, replaced by cold morning air slipping through the seams. I sat up slowly, wincing at the deep ache, and listened. Outside I could hear voices, Mom making coffee, Dad poking at the fire, my sister laughing at something. No sign of him. The soreness inside me felt like proof. Like a brand he had left there on purpose. Every shift reminded me that he had been buried in me, that he had called me his bitch while he filled me, and that I had taken it like I was made for it.

I pulled on my shorts and crawled out. Stephen was already up, looking fresh in a tight thermal shirt that hugged his chest and arms, mullet slightly messy from sleep, that thick mustache framing his easy grin. He did not even glance my way when I emerged. Not a smirk, not a knowing look. Nothing. He just clapped my dad on the shoulder and joked about the bacon burning while he helped flip it. The normal act made my stomach twist. He could stand there like nothing had happened while my ass still remembered the stretch of his cock.

The rest of the trip was like that. He acted completely normal. Too normal.

He did not mention the tent, the blowjob, or the way he had fucked me raw and pumped me full. But he made sure I felt it anyway. When we sat around the fire that evening he planted himself right across from me, legs spread wide, grey sweat shorts pulled up high so the fabric bunched tight around his heavy bulge. The thick outline of his cock was impossible to ignore, especially when he casually adjusted himself, big hand cupping and shifting it while talking to my parents. His eyes would flick to mine for half a second, just long enough for that cocky little spark to show before he looked away again.

He was extra handsy with my sister too. Kissing her neck, squeezing her ass when he thought no one was looking, pulling her into his lap by the fire. That night he convinced her to turn in early, loud enough for everyone to hear. “C’mon baby, you still owe me for that migraine last night,” he said with a laugh, guiding her toward their tent with a possessive hand on her lower back. I sat there burning, knowing exactly what they were about to do while my own ass still leaked the remnants of him. It was not just jealousy. It was the knowledge that he had already used me, that I had taken his load while she slept nearby, and now he was going to fuck her like nothing had changed. The thought made my stomach twist and my cock stir at the same time. I felt so used, like a secret slut he had already discarded, but that only made the heat worse. He had degraded me in the dark and now he got to play the perfect boyfriend in front of everyone while I sat there hard from the memory.

When I went to piss that first morning and a thick, warm glob of his cum slid out of me and down my thigh, I knew it had not been a dream. The rest of the trip I walked around in a strange haze, half convinced I had imagined the whole thing, half throbbing every time he stretched or flexed or spread his legs. Every time I sat down I felt the ghost of him inside me. Every time I jerked off alone I replayed the moment he called me princess and bitch while he bred me, and I came hard each time.

The summer passed in fragments. I only saw Stephen a handful of times. He was working construction most days and then headed back to college. Each encounter was brief and painfully normal. He would slap my shoulder, call me “little bro,” and act like nothing had ever happened. It felt like a one-off. Forgotten.

Except I could not forget. I jerked off dozens of times to the memory, his thick cock stretching my throat, the burn of him forcing his way into my ass, the way he growled “good girl” while breeding me. I followed his Instagram just to torture myself, stroking furiously to every gym mirror selfie, every shirtless construction site shot where sweat made his chest hair cling to his heavy pecs. I came harder than I ever had in my life to those pictures, whispering his name like a dirty secret, hating how much what he had done to me had got inside my head.

Thanksgiving break arrived and they came home for the long weekend. The second Stephen stepped through the door, duffel bag over one broad shoulder, I felt it again, that overwhelming, shy flush. He looked bigger than I remembered. Tighter thermal shirt, jeans hugging his thick thighs, that same confident smirk under the moustache. I could not help but stare for a second before dropping my eyes.

“Little bro!” he boomed, pulling me into a quick, firm hug that pressed his hard body against mine. He smelled like cologne and man. “How you been, man? You look good.” Having him touch me again made my mind swim, I was filled with overwhelming desire, lust and honestly a surge in the shame I had felt after it had first happened. Shame at the way I had let him use and degrade me, but also shame at the way I had loved every moment of it and wanted it again.

He was friendly the whole afternoon. Asking about school, joking around with Dad, helping Mom in the kitchen like the perfect son-in-law. I started to relax. Maybe it really had been a drunken one-time thing. Maybe he had moved on.

We were all drinking before dinner, beer and whiskey flowing while the turkey cooked. Stephen put away more than anyone, but the big bastard handled it like a champ. The more he drank, the louder and more jovial he got, laughing deep from his chest, slapping backs, filling the room with his presence.

After one trip to the kitchen for another beer he dropped down on the sofa right next to me instead of his usual spot. We were watching the football game, Dad on the other side chatting stats with him. For a while everything felt normal.

Then his big hand settled on my lower back.

I tensed immediately. His palm was warm, heavy, rubbing slow circles just above the waistband of my jeans. My sister and Mom were in the kitchen. Dad was focused on the TV. Stephen kept talking football like nothing was happening, but his fingers slowly dipped under my waistband, sliding down the smooth skin of my crack. The tip of his index finger traced lower, lower, brushing right above my hole before stopping. I whimpered, actually whimpered, soft and broken.

My mind went white for a second. This was not the tent. This was the living room with my dad three feet away. And yet the touch felt exactly like being claimed again. The same casual ownership. The same way he had decided my body was his to touch whenever he wanted. My cock twitched hard in my jeans. My hole clenched on nothing, remembering how it had felt to be stretched open and filled while he called me his bitch. The shame hit fast and hot. I was getting hard from my sister’s boyfriend secretly fingering my crack. I was pathetic. I was his.

Dad glanced over with a funny look. “You alright, son?”

Stephen’s hand withdrew smoothly, innocent as anything. “Yeah, he’s good,” he chuckled, giving my shoulder a brotherly squeeze. “Probably just nervous about that paper he was telling me about earlier.”

I nodded quickly, face burning, heart hammering so hard I was scared everyone could hear it. My cock stayed half-hard. My hole kept clenching like it was waiting for more. The worst part was how natural it felt. Like this was just what happened now. He touched me however he wanted and I took it because that night in the tent had already decided it for me.

At dinner Stephen patted the chair right beside him.

“Come on, little bro,” he said with that easy, charming grin, “sit next to me. I want to hear all about school.”

My sister laughed and told me to go ahead. Mom smiled like it was the sweetest thing. I slid into the seat beside him, thighs brushing under the table, his body heat radiating into me.

He was still smiling like a friendly older brother.

But under the table, his knee pressed firmly against mine and stayed there.

His hands continued to wander through dinner and I was on edge the whole time. Every brush of his fingers against my thigh sent another pulse straight to my cock. I could feel pre soaking into my underwear. My hole twitched with the memory of his load still buried deep from months ago. This was Thanksgiving dinner. My parents were across the table. My sister was right there laughing about something. And Stephen’s hand was drifting under the table like he owned the space between my legs. The contrast made it worse. He talked to my dad about the game like nothing was happening while his fingers traced the seam of my jeans, slow and deliberate. Every touch reminded me that I had already surrendered once. That I had dropped to my knees for him, let him call me princess and fag and good girl while he used my mouth and then my ass. That I had pushed back onto his cock because I wanted to be owned. Now he was testing how far that ownership went in plain sight.

I could not deny the dark thrill running through me. His attention made me feel desired in that same twisted way from the tent. The idea of him using me again, right here under everyone’s noses, sent a hot pulse straight to my dick even as my stomach twisted with how wrong and risky it was. I had to fight every second not to react, not to lean into his touch or let my breathing give me away. At the same time part of me wanted him to push further, to see if I would break and whimper again with my whole family in the room. I hated how much I wanted that. I hated how much it turned me on to sit there pretending to be normal while my sister’s boyfriend secretly reminded me that I was already his secret hole.

I was so nervous I barely ate. My mother kept asking if I was okay despite my assurances that I was. I promised her the food was delicious but that all of a sudden my stomach felt a little unsettled, that was all. Every time Stephen’s hand drifted under the table my mind flashed back to the tent, to being on my knees, to the way he had called me princess and bitch while he bred me. My face stayed hot. My dick stayed half-hard.

After everyone had their fill of turkey and potatoes and all the other dishes my mother had prepared she cleared the table and suggested we wait a while before dessert which everyone agreed to.

While my sister and father were chatting about something and not paying attention Stephen leaned in to my side. His hand moved to my lower back and then to the top of my waistband, the tip of his finger slipping just into the crack of my ass. “Bathroom now.”

I looked at him in alarm. He could not be serious. But the stern look that flashed across his face told me he was deadly serious.

I glanced away, my mind racing. Even if I wanted to, I could not say no. He had marked me that night in the tent, subdued me, claimed me. I was always going to do what he told me to do. The thought did not feel like defeat anymore. It felt like the only thing that made sense. He had already turned me into his bitch once. Sitting here pretending otherwise was pointless. My body knew it. My hole knew it. My cock knew it. I was going to stand up, walk to that bathroom, and let him do whatever he wanted because that was what I had become the moment he finished inside me and called me good girl.


I looked back to my dad and sister sitting there and then back at him. Then I rose, gave my excuses, and headed out of the dining room and down the hall to the bathroom at the front of the house. I waited inside with the door unlocked like he expected. What was he planning? Was he going to fuck me right here with my family waiting for us to come back? That would be madness. Even so I told myself I would refuse. I could not let it happen. Not here. Not with them so close.

A few minutes later there was a knock and he came in. Fuck he was so sexy, but he did not give me time to think. He shoved me against the wall, one big hand pinning my shoulder.

"Fuck, you really are a disgusting slut, aren't you? Nothing but a whore. It's pathetic. I half expected you to already be on your knees in here waiting for me. What kind of sick freak keeps giving their sister's boyfriend doe eyes across the room and gets a little boner whenever he innocently squeezes your shoulder? It's tragic, frankly."

His words stung, but as he towered over me I felt compelled to sink to my knees. The floor was cold under me. My heart hammered so hard I could barely hear anything else. This was the second time. The second time I was about to have my sister's boyfriend's cock in my mouth. The thought made my stomach twist with shame, but my own dick was already straining in my jeans.

Stephen smirked down at me and hooked his thumbs in his waistband. He shoved his jeans and briefs down just far enough, only to the middle of his thick thighs. His cock swung free, already half hard, heavy and thick. He gripped the base and rubbed the fat head slowly across my lips, smearing a bead of pre over them.

"Beg for it, princess. You want this cock again, don't you? Say it."

I swallowed, face burning. My lips parted on their own. "Please."

He chuckled, low and mean, and rubbed the head back and forth, teasing my mouth, letting me taste him but not pushing in. "Please what? Use your words, you pathetic little cocksucker. Tell me what you want."

My voice came out small and wrecked. "Please let me suck it."

He slapped my cheek with his cock, the weight of it thudding against my face. Once. Twice. The third time he left it resting against my cheek, hot and heavy.

"Look at you. On your knees in the bathroom while your family sits at the table. Your sister's boyfriend's cock slapping your face and you're leaking in your pants like a bitch in heat. Say it louder. Beg properly."

I looked up at him, eyes watering already from the humiliation. "Please, Stephen. Please let me suck your cock. I need it."

He grinned, mean and satisfied, and finally pushed the head past my lips. The taste hit me instantly, salty and musky, exactly like I remembered from the tent. He did not ease in. He fed it to me in one slow thrust until my nose pressed against the thick patch of hair at the base. My jaw stretched wide. My throat convulsed around the intrusion.

This was only the second time I had ever sucked a cock. The first time had been in the dark, half drunk, terrified and thrilled. This time the light was on. My family was thirty feet away. And it felt even more right. The stretch, the weight on my tongue, the way my throat had to open for him, it all clicked into place like a lock turning. This was what I was born for. Not to sit at the table pretending to be normal. Not to chase girls or act like I wanted the life everyone expected. I was born to be on my knees with a real man's cock in my throat, taking whatever he gave me, reduced to a hole for his use.

He held me there for a long moment, letting me choke and adjust, then started to fuck my face in short, controlled thrusts. His hand gripped the back of my head, guiding me, using me.

"That's it. Good girl. Take it deep. You were made for this, weren't you? All that quiet little brother act and underneath you're just a desperate throat for me to use. Your sister has no idea her boyfriend turns her little brother into a cocksleeve every chance he gets."

Tears pricked at the corners of my eyes from the stretch and the words. My own cock throbbed untouched in my jeans. Every thrust sent a fresh wave of shame and heat through me. I was doing this again. I was choosing this again. And the worst part, the best part, was how much I loved it. How complete it made me feel. The tent had broken something open in me. This was just confirming it. I was his. His secret slut. His throat to fuck whenever he wanted.

He pulled back just enough for me to gasp a breath, strings of spit connecting my lips to his cock. Then he shoved back in, deeper, and started fucking my throat in earnest. The wet sounds filled the small bathroom. I gagged and swallowed around him, trying to be good, trying to take it the way he liked.

"Fuck, look at you. Eyes all glassy, drooling down your chin. You love this. You love being my dirty little secret. Bet you're thinking about how you're going to sit back at that table with my cum in your stomach while everyone talks like nothing happened."

I moaned around him. The vibration made him groan and thrust harder. My mind spun with it. The risk. The ownership. The way every degrading word only made me harder. I was sucking my sister's boyfriend's cock for the second time in my life and all I could think was that I never wanted it to stop. That this was the only place I belonged.

He fucked my throat for what felt like forever and no time at all. Then he pulled out, gripping his cock, stroking it fast right in front of my face.

"Beg for it, bitch. Beg for my cum down your throat."

I did not even hesitate. My voice was hoarse and wrecked. "Please. Please cum down my throat. I want it. I need it. I'm your slut. Please paint my throat."

He groaned, low and rough, and pushed back in just as he started to cum. Thick, hot pulses flooded my mouth and throat. I swallowed as fast as I could, but some leaked out the corner of my mouth. He held me there until he finished, making sure I took every drop.

When he finally pulled out I stayed on my knees, panting, lips swollen and shiny. My throat felt used and raw. My head felt floaty and clear at the same time.

Stephen did not say anything else. He just hooked his thumbs in his waistband and pulled his jeans and briefs back up from where they had stayed at mid-thigh the whole time. He tucked his cock away, zipped up, and checked his reflection in the mirror like nothing had happened. Less than fifteen minutes from the moment I left the table to now.

He glanced down at me once, that same cocky smirk on his face.

"Clean yourself up and get back out there, princess. Don't keep everyone waiting."

Then he was gone, the door clicking shut behind him.

I stayed on the floor a moment longer, cum still thick on my tongue, the taste of him coating my throat. Any chance I had of pulling away from his dominance had gone forever. The tent had started it. This had sealed it. I was his now, completely, and we both knew it.

But it was more than that. Sucking his cock again, here in this bathroom with my family so close, had done something permanent to me. It was not just the act. It was what the act revealed about the urge that had always been there, buried under years of pretending. I had spent so long trying to be the quiet, normal guy, the one who blended in at family dinners and never caused trouble. Yet the second Stephen gave me that look, the second his hand found my lower back under the table, every bit of that pretence had crumbled. The urge to drop to my knees for a bigger, stronger, straight man like him was not something I could reason with or negotiate. It was primal. It was the part of me that wanted to be smaller, weaker, owned. The part that got hard from being called a slut and a whore by someone who could physically overpower me without even trying.

There was something about the dynamic that went deeper than just liking cock. It was the surrender to someone who would never see me as an equal. Stephen was my sister's boyfriend. He was the kind of guy who who filled a room with his presence, who fucked girls like it was his right. And here I was, on my knees in a bathroom, throat sore from taking him, swallowing his load because he told me to. The humiliation of it was the point. The fact that he could go back to the table and laugh with my dad while I sat there with his cum still warm in my stomach only made the urge stronger. It confirmed the hierarchy. He was the man. I was the hole. And the sick, addictive part of me loved that I would never be able to un-know it.

Sucking him the first time in the tent had been overwhelming, half accident, half booze-fuelled need. This time I had walked to the bathroom knowing what was probably coming. I had made the choice with my eyes open. That changed everything. It meant the urge was not going away. It meant that every time I saw him from now on, part of me would be waiting for the moment he decided to use me again. The second time on my knees had locked something into place. I could still taste him. My jaw still ached. My throat still felt stretched and claimed. And instead of shame making me want to run, it made me want to stay right here on the cold floor a little longer, replaying every degrading word he had said.

This was what submissive guys like me were wired for. Not the gentle, equal stuff. The raw, one-sided thing where a bigger, stronger, straight man decided you were there to serve his cock and you thanked him for it. The way his hand had gripped my head, the way he had slapped my face with it, the way he had made me beg while my family waited, it all fed the same need. I wanted to be reduced. I wanted to be nothing but a warm, willing throat for someone like him. The more he treated me like a pathetic secret slut, the more complete I felt. It was the opposite of everything I was supposed to want, and that was exactly why it felt so right.

I finally pushed myself up, wiped my mouth, and checked my reflection. My eyes were red. My lips looked used. I still had the faint taste of him every time I swallowed. When I walked back into the dining room and slid into my seat beside him, my legs felt unsteady. Stephen was already laughing at something my dad said, acting like he had never left the table. His knee pressed against mine under the cloth again, casual and possessive. I did not pull away. I could not. The urge had won. It had always been going to win. And now that I had sucked his cock for the second time, I knew I would be on my knees for him again the next chance he gave me. Not because he forced me. Because the part of me that needed to submit to men like him was louder than any other part of my life. It was who I was.
