Hey, this is my first story and English is not my native language, so I excuse myself for any mistakes that may occur. This is a fictional story that involves incest, hence leave if this is not suited for you.
My cousin Theo and I had always been inseparable. Three years younger than me, he had a way of tagging along wherever I went, his curious energy a constant presence. Growing up, his house felt more like my second home than just a place to visit. Every weekend for over a decade, I’d arrive with my overnight bag, greeted by the familiar scent of freshly baked bread and the sound of Theo’s laughter echoing through the halls.
We did everything together—building forts out of old blankets, racing bikes down the hill behind their house, and staying up late whispering secrets under the glow of a flashlight. He wasn’t just my cousin; he was the brother I never had. Given the age difference, Theo had always been a little shorter than me—not by much, but just enough for me to make it a point of teasing him whenever the opportunity arose. He’d roll his eyes, mutter something under his breath, and inevitably challenge me to prove my so-called superiority. Our play fights were frequent, almost ritualistic, the kind of battles only boys could turn into a matter of pride. It always started the same way—a shove, a laugh, a daring grin—and ended with me pinning him down, triumphant. He would wriggle beneath me, red-faced but grinning, his protests half-hearted as he tried, and failed, to twist free from my grip.
“You always cheat,” he’d accuse breathlessly, though we both knew it wasn’t true. It was simply the nature of our dynamic: my strength against his determination, a contest that always ended in my favour. Theo was always a bit on the chubby side, a trait he seemed to embrace with little hesitation—or perhaps he simply didn’t care enough to fight it. He had an insatiable appetite, something that often became the subject of teasing from me. While I could barely manage a single helping, Theo would plough through two, sometimes three plates at dinner, unfazed by the raised eyebrows of the adults around the table.
“You’ll eat us out of house and home one day,” I’d quip, leaning back in my chair, smirking as he reached for yet another portion. He’d scowl in my direction but never truly retorted, his mouth too full to offer much more than a muffled protest. That didn’t stop me, of course. I’d poke fun at his round cheeks or the way his uniform shirts strained ever so slightly at the buttons, tossing out nicknames like “Tubby” or “Butterball” with the kind of casual cruelty boys often confuse for affection. It irritated him, that much was clear—the way his ears would flush a deep red or how he’d glance away, muttering under his breath. But no matter how much it got under his skin, there wasn’t much he could do about it. He was Theo, after all, and I was me. That was just the way things were.
During my late teen-age years, I found myself consumed with the pressures of school and the increasing demands of my social circle. The time I once had to spend with Theo—those endless weekends of mischief and laughter—became a rare commodity. He, on the other hand, had entered high school and seemed to fall into a crowd of his own, making friends at every turn. We no longer spent the same amount of time together, but it wasn’t something either of us questioned. It felt natural, almost as though the distance between us was inevitable, a part of growing up.
Still, from time to time, I’d ring him up to see how he was getting on. His voice would crackle with energy on the other end, telling me about the parties he’d been to, how he’d gotten drunk again with his new friends—every weekend, it seemed. Each time we spoke, I noticed the subtle shift in his voice, a growing depth that made him sound less like the boy I’d known and more like someone else, someone older. It was hard not to notice the change; it seemed as if he was shedding the remnants of his childhood with every conversation. I’d always let him know I was doing well, too. School was fine, nothing too difficult, and I was keeping busy, just like he was. It didn’t feel like there was much more to say; the updates were simple, but we didn’t need much more. We didn’t have to talk every day to know what the other was up to, but it was nice to hear his voice now and then.
For the third year of university, I had decided to be an exchange student in another country, and I had just finished that period. When the next summer rolled around, my uncle invited me on a trip with him, his wife, and Theo. I was supposed to return several days before them, but since I was already closer to where we were going, I decided to meet them directly there. It seemed like a good way to kick off the summer vacation, and it was easier to head straight there without going home first.
I was 21 by then, and Theo was 18—still growing, still changing. We had shared countless memories over the years, but I couldn’t help but notice how much he had transformed in the short time I’d been away. The thought of spending time with him again, just the two of us, felt strangely exciting. We were going to stay in a hotel, and my uncle had arranged for two rooms—one for himself and his wife, and another for Theo and me. It wasn’t the first time we’d shared a room, but this time felt different somehow.
It was a hot summer day when my uncle and Theo met me at the airport. The moment I laid eyes on him, I couldn’t quite believe what I was seeing. Of course, I recognised him instantly, but his physical appearance had changed so much that it took me a moment to adjust. Theo was no longer the same boy I remembered. He was a lot taller than me now, easily standing at around 6’3”, and he looked... massive. What used to be soft and round had transformed into thick, defined muscles that stretched the fabric of his tight t-shirt to the limit. His biceps bulged, thick and powerful, and his chest—well, his pecs seemed to strain against the material, as if daring to break free. His jawline was sharp, more defined than I remembered, and the rest of his features—his dark, bushy eyebrows, piercing blue-green eyes, and full, plump lips—gave him an almost intimidating presence.
I didn’t have time to process it before he was right there, pulling me into a hug. His arms were heavy around me, strong, gripping me tightly as if he never wanted to let go. I reached around his broad back, completely taken aback by how much larger it had become. He was practically leaning down, towering over me, his figure dwarfing my 5’4’’ body, his massive muscles almost lifting mine off the ground. He held me like that for what felt like an eternity, yet it was only about ten seconds—silent, with only the sound of our breathing between us.
He was sweaty, his skin warm against mine, and I couldn’t avoid the scent that filled my nose. It was his musk, thick and earthy, the kind of smell that clung to him like it belonged there. It was undeniably masculine, and the way it hit my nose felt oddly... satisfying, even in its rawness.
After the hug at the airport, I still couldn’t fully shake the feeling of Theo’s arms around me—his strength, the way he seemed to swallow me up in that embrace. As we walked toward the parking lot, my uncle took the lead, with Theo right beside him. Theo didn’t waste any time—he grabbed my luggage from me, his large hand effortlessly wrapping around the handles, and I felt a slight flush of heat at how naturally he took charge.
“Don’t worry about it, I got this,” Theo said, his voice still deep with that confident edge. His words should have been reassuring, but the weight of his tone made my stomach do a little flip.
I slid into the back seat of the car, watching as Theo climbed into the front passenger seat, his broad shoulders filling the space. The moment he settled in, the car seemed smaller, somehow. My uncle started the engine, pulling out onto the road. The hum of the car and the low murmur of the radio filled the space, but there was a noticeable distance between Theo and me—like something was hanging in the air, unspoken.
Theo glanced back at me through the rearview mirror, catching my eye for just a moment. A small, playful smirk danced on his lips, but he didn’t say anything, and I quickly looked away, trying to calm the fluttering in my chest.
When we arrived at the hotel, the lobby was a cool oasis from the summer heat, the polished floors reflecting the soft light of overhead lamps. My uncle checked us in, and after a few minutes, we were handed the key to our room.
"Here you go," my uncle said, passing me the key. "Room 302. You two share the number.”
We made our way to the elevator, my uncle pressing the button to take us up, and once inside, Theo leaned against the wall, still holding my luggage. I was standing a bit too close to him, and I could feel the heat radiating off him, his presence like a wall I couldn’t escape. I tried not to let my thoughts wander.
The elevator pinged as it reached our floor, and we stepped out into the hallway. My uncle led the way to the room, and once we were inside, he opened the door to reveal the king-sized bed and the simple, sleek décor of the room.
“Well, here we are,” he said, as Theo set down my suitcases. “You two will have plenty of space. Just let us know if you need anything.”
Theo and I exchanged a quick glance, and I felt a shiver run down my spine. The room, though nice, seemed suddenly too small for the two of us. There was only one bed.
"You’re good with the bed, right?" he asked, trying to keep my tone light. "Which side do you want?"
“I paused, feeling a heat rise in my chest, but I shrugged it off. “Doesn’t matter, you?” I said quietly, my voice carrying a weight I hadn’t meant for it to.
Theo grinned, the smirk returning. “I’m fine with whatever, man. You’re the one who looks like you’ll need the space.”
I didn’t respond immediately, caught off guard by how comfortable he was with it, with us in this space together. But we didn’t linger on it for too long. My uncle and his wife were already heading out for a walk, leaving us alone in the room. The silence that settled between us felt heavy, charged in a way I wasn’t sure how to handle.
Later that evening, we headed down to the hotel restaurant, a warm, inviting space that was both casual and upscale. The lighting was low, casting a soft glow over everything, and the hum of conversations around us created a relaxed atmosphere. We were seated in a corner booth, my uncle and Theo on one side, with his stepmother and I sitting across from them.
Theo seemed at ease, talking about his week with my uncle as they laughed over some inside joke. I couldn’t help but watch him—how his muscles flexed as he reached for the breadbasket, how his voice, deep and rich, seemed to fill the air around us. He was so... different now. It wasn’t just his size, though that alone was enough to make me feel a little off-balance. It was everything about him—his presence, the way he carried himself, the way he looked at me.
“So,” Theo said between bites of food, glancing at me across the table, “what’s been the best part of your exchange year?”
I blinked, momentarily caught off guard by the question. I had expected the usual banter, the easy conversation we used to share, but this felt different. His voice, steady and grounded, made me feel like I was under a spotlight.
“Just getting to see new places, meeting new people,” I said, my voice sounding lighter than I felt. “It was a pretty crazy experience. What about you? Still getting into trouble?”
Theo laughed, but there was something darker in it now, something that hinted at experiences I hadn’t been a part of. “You could say that. New friends, new experiences... and some stuff I probably shouldn’t mention.”
My uncle chuckled from the other side of the table, oblivious to the tension building between Theo and me. But I could feel it, thick and heavy, like a pressure in my chest. Every glance Theo sent my way seemed deliberate, like he was waiting for me to acknowledge the shift between us.
The meal continued, but I couldn’t focus on the food. The only thing on my mind was the fact that we were alone in that hotel room, sharing a bed. The thought of being so close to him, the weight of his body next to mine, was almost too much to ignore.
As we finished our meal and prepared to head back to the room, I couldn’t shake the feeling that something had irrevocably changed between us. The air between Theo and me was charged now, in a way I didn’t fully understand, but I knew it was only a matter of time before we couldn’t ignore it any longer.
After and returning to our room, I suddenly remembered I’d left the ring my grandmother gave me down in the restaurant. I didn’t want to bother Theo—he was already halfway to the bathroom, peeling off his clothes, ready for a shower. I told him he could go ahead while I quickly stepped out to grab it. As I closed the door behind me, I felt a strange sense of relief. For the first time in hours, I was alone with my thoughts.
Theo’s transformation was still rattling around in my mind. The way he’d changed so much physically—how massive he’d become. It was hard to wrap my head around, and I needed a moment to gather myself. Everything about him had shifted, and not just in size, but in presence.
The elevator ride down felt too short, though it was only a few floors. I kept trying to push away the confusion, but it stuck with me, a constant undercurrent. I grabbed my ring from the table where we had dinner and went outside for a smoke, the cool air offering some relief. I needed a minute—just a minute—to process everything without it all rushing at me at once.
I had lost track of time, but when I returned to the room, the sound of the shower running filled the air. I figured I’d lie down and rest while I waited. As I settled into the bed, I couldn’t help but notice the clothes Theo had left scattered across the floor beside his side. My eyes landed on his boxer shorts, casually tossed aside, and despite myself, my gaze lingered. A strange warmth spread through me—unexpected, and hard to shake off—as I took in the faint scent that seemed to linger in the air. The smell clung to the room, an odd mix of him, the day’s heat, and something I couldn’t quite put my finger on.
I tried to pull my attention away, but my mind kept drifting back. The water was still running, and I found myself imagining how long it would take him to finish. Just enough time for me to throw his boxers back on the floor, I thought, but my hands didn’t listen. They reached for them almost instinctively. Black Calvin Klein, worn soft with age. I had a few pairs myself—though the smallest ones I owned never sat as snugly as these. I expected them to be a large, but to my surprise, they were XXL. My fingers traced the waistband for a moment longer than I intended, and the thought of how they might fit him made something stir inside me. I quickly pushed the thought away. They wouldn’t fit me the same way they fit him, I reasoned, trying to ignore the way my chest tightened slightly. But then again, maybe they didn’t fit him the way mine fit me either...
The sound of the shower shutting off jolted me from my thoughts, and I quickly realized time was running out. My hand still hovered over Theo's black Calvin Klein boxers, which I had barely tossed back onto the floor just as the bathroom door clicked open. The bathroom door opened with a soft click, and a rush of steam followed Theo out. His figure emerged slowly, silhouetted against the warm light spilling from the doorway. He had a towel draped low around his hips; his damp skin gleaming under the overhead light. Droplets of water trailed down his chest, tracing over the ridges of his pecs and the valleys of his abs through his happy trail before disappearing into the white fabric.
I swallowed hard, my throat dry. He was indeed a lot bigger than I remembered. Every part of him seemed sculpted, like a statue carved out of raw strength and power. His shoulders were impossibly broad, his arms thick and veined, and his chest rose and fell rhythmically as he towelled his hair dry with a smaller towel. Even his legs were massive, the muscles rippling with every step he took toward me.
I tried not to stare, but my eyes betrayed me, tracing the line of his collarbone, the subtle curve of his biceps, and finally, the dark tufts of hair under his arms, visible when he reached up to dry the back of his head. My breath hitched, and I quickly looked away, feigning interest in the faint patterns on the carpet.
But Theo wasn’t oblivious. “You okay?” he asked, his voice deep and warm, carrying a note of teasing. I forced a laugh, my gaze still fixed on the floor. “Yeah, fine. Just tired.” Theo smirked, letting the towel fall around his neck. “You’ve been staring at me all day, you know.” My head snapped up, my heart racing. “What? No, I haven’t.”
He chuckled, the sound low and confident. “Relax. I don’t mind.” He stepped closer, his presence filling the space between us. “I worked hard for this, you know,” he added, gesturing to his body. “I’m not the same kid you used to pin down and tease.”
I tried to respond, but the words caught in my throat. He wasn’t wrong. He wasn’t the same kid anymore. He was a man now—a man whose physicality dominated the room, whose confidence was almost magnetic. And he knew it. He knew what he was doing to me. Theo flexed his arm, his bicep swelling under his skin, and grinned at me. “Pretty big, huh?” he said, his tone playful but carrying an edge of pride. “Bet you didn’t think I’d end up like this.”. My body betrayed me as I felt an undeniable response from my crotch.
I couldn’t help but glance at him, at the sheer size of his muscles. My stomach churned with a mix of emotions—admiration, envy, guilt, and something else I couldn’t quite name. “You’re, uh... definitely big,” I muttered, trying to sound casual. He laughed again, this time softer, almost kind. “Come on,” he said, stepping even closer. “You can touch if you want. I won’t bite.”. My heart pounded so loudly I was sure he could hear it. “Theo, I don’t think—”
“Don’t think,” he interrupted, his voice low and steady. “Just feel.” Before I could protest, he took my hand and placed it on his bicep. His skin was warm and firm under my palm, my fingers twitched slightly, instinctively pressing against him. He didn’t pull away. If anything, he leaned into the touch, flexing harder, showing me just how big he was. “See?” he murmured, his voice softer now, almost soothing. “It’s not weird. It’s just me.”
I wanted to pull my hand away, but I couldn’t. My fingers moved on their own, finding his pecs, tracing its curve, the hardness of his body contrasting with the warmth radiating from his skin. My gaze flickered up to meet his, and I saw something in his eyes—something tender, almost vulnerable, beneath the confidence. “It’s okay,” he said again, his tone gentle now. “I’m not judging you.”
I swallowed hard, my mind racing. Every instinct told me to stop, to push him away, to remind him that this was wrong—that he was my cousin, my brother in all but name. But my body wasn’t listening. The weight of his hand on mine, the steadiness of his presence, the softness in his gaze—it was too much.
Theo stepped back slightly, breaking the moment, and I felt a strange pang of loss. He sat on the edge of the bed, the towel still slung low on his hips, and looked up at me with a small, almost shy smile. “You know, I used to look up to you,” he said quietly. “I wanted to be like you—confident, strong, unafraid to be yourself.”
I blinked, startled by the sudden vulnerability in his voice. “Theo...”. He shook his head, cutting me off. “I’m not saying that to make you feel bad. I just mean... it’s funny how things change, huh? Now I’m the one who’s bigger, stronger.” His grin returned, but it was softer now. “Guess I kind of like that.”
I didn’t know what to say. The air between us felt heavy, charged with something I couldn’t name. He patted the space next to him, inviting me to sit, and I hesitated before finally giving in. The bed dipped slightly under my weight, and I was acutely aware of how close we were, how his leg brushed against mine.
For a moment, we just sat there, the silence stretching between us. Then, slowly, Theo leaned back, propping himself up on his elbows. His body stretched out, his abs tightening, his chest rising with every breath. He was showing off, and he knew it.
“You’ve been quiet,” he said, his voice soft but teasing. “Not like you.”
I tried to laugh, but it came out weak. “Just... processing, I guess.”
Theo smirked, his gaze locking onto mine. “You’re allowed to admire me, you know. I don’t mind.”
I looked away, my face burning. “It’s not that simple.”
He reached out, his hand brushing against mine, grounding me. “It doesn’t have to be complicated,” he said gently. “It’s just us.”
The bed seemed to shrink around us, the space between us disappearing. Theo leaned in slightly, his presence overwhelming, his eyes searching mine. He was waiting, giving me the choice, the control. And in that moment, I didn’t know if I could resist.
Theo shifted, standing briefly before heading over to his side of the bed. The mattress dipped under his weight as he sat down, the towel around his waist loosening slightly. His movements were unhurried, deliberate, as though he wanted me to watch him. I tried to keep my gaze fixed on the wall, but the magnetic pull of him was impossible to ignore.
“You gonna just sit there all night?” he asked, his voice warm and teasing. He leaned back, propping himself up with one hand as he patted the space beside him with the other. “Come on, it’s a big bed. Plenty of room.”
I hesitated, the internal tug-of-war between my instincts and my desires raging inside me. But Theo’s eyes—steady, kind, and yet undeniably confident—offered a strange sort of reassurance. This wasn’t a trap; it wasn’t a game. It was just him, being... him.
I moved cautiously, the sheets cool beneath my hands as I slid onto the bed. The distance between us felt electric, every inch closer intensifying the charge. He let out a low chuckle, the sound rumbling deep in his chest as he adjusted himself, lying back fully.
With a stretch, Theo placed his hands behind his head, his massive biceps flexing effortlessly as his elbows jutted out to either side. The motion pulled his towel even lower on his hips, but more than that, it revealed the thick tufts of hair under his arms. My stomach tightened at the sight, and I tried to keep my expression neutral, but the faint musk that wafted from him filled the air, unmistakable and entirely him. It wasn’t overpowering—just raw and earthy, like a signature he carried without apology.
“You okay over there?” he asked, his tone light but his eyes sharp, watching me closely.
“Yeah,” I lied, my voice barely above a whisper. My fingers curled into the sheets, trying to anchor myself, but my body betrayed me. Every glance, every breath, seemed to draw me closer to him, like gravity had shifted in his favour.
Theo smirked, the corners of his mouth twitching upward. “You’re quiet again. Not used to seeing you like this.”
I swallowed hard, unsure of how to respond. Before I could muster an answer, he shifted slightly, turning onto his side to face me. His arm rested casually across his hip, the sheer size of it dwarfing the space between us.
“You don’t have to be nervous, you know,” he said softly. “It’s just me.”
“That’s the problem,” I muttered without thinking, the words slipping out before I could stop them.
He raised an eyebrow, clearly amused. “Oh yeah? What’s the problem?”
I shook my head, refusing to look at him. “Nothing. Forget I said anything.”
Theo leaned closer, his voice dropping to a near whisper. “It’s not nothing. Come on, talk to me.”
His tone was gentle, almost coaxing, and when I finally glanced up, his eyes held no trace of mockery—only curiosity and something deeper, something I couldn’t quite name. It was disarming, the way he could switch so easily from playful to sincere, making me feel seen in a way I wasn’t prepared for.
“You’ve changed,” I admitted quietly. “A lot.”
He nodded, a small smile playing at his lips. “Yeah, I guess I have.”
“And you know it,” I added, my voice sharper than I intended.
Theo laughed softly, the sound warm and rich. “Of course I know it. But that doesn’t mean I’ve changed who I am. I’m still your Theo. Always will be.”
The words hit me harder than I expected, and for a moment, I didn’t know what to say. He shifted again, this time lying flat on his back, his hands returning behind his head. The movement sent another wave of his scent into the air, and I couldn’t help the way my breathing quickened, my body responding despite my best efforts to ignore it.
“You can get closer, you know,” he said after a moment, his voice soft but firm. “I don’t bite.”
I hesitated, but the way he looked at me—patient, inviting—made it impossible to resist. Slowly, I inched toward him, the space between us shrinking until my shoulder brushed against his chest. He didn’t move, didn’t push, just let me settle there, his presence grounding me.
“Better?” he asked, his tone light but carrying a note of genuine care.
I nodded, unable to speak. The warmth of his body seeped into mine, the steady rise and fall of his chest lulling me into a strange sense of calm. His arm shifted, and before I realized what was happening, he wrapped it around me, pulling me closer. My head rested against his chest, the solid weight of him beneath me both overwhelming and comforting.
For a while, neither of us spoke. The only sounds were our breaths and the faint hum of the air conditioner. I felt his hand move, his fingers tracing idle patterns on my shoulder, and the tenderness of the gesture nearly undid me.
“You smell good,” I said before I could stop myself, the words slipping out in a quiet, nervous laugh.
Theo chuckled, the sound vibrating through me. “Thanks,” he said simply, his voice carrying a smile.
I felt his arm tighten slightly around me, his other hand brushing against my back as he shifted, adjusting until I was nestled against him fully. My head fit perfectly against the curve of his shoulder, my face inches from the hollow of his armpit. The scent was stronger here, unfiltered and undeniably him. It should’ve been too much, but instead, it felt... safe. Familiar. Like home.
“Comfortable?” he asked, his voice barely above a whisper.
“Yeah,” I murmured, my eyes growing heavy. The warmth of him, the steady rhythm of his breathing, the way his muscles enveloped me—it was all too much and yet not enough.
Theo’s fingers brushed through my hair, a soothing motion that sent a shiver down my spine. “Good,” he said softly. “You’re safe with me. Always.”
The words settled over me like a blanket, and before I knew it, my eyes were closing, sleep pulling me under. The last thing I felt was Theo’s arm tightening around me, his body a fortress against the world, and his scent—raw, warm, and comforting—surrounding me completely.
For the first time in a long time, I felt entirely at peace.
To be continued..
