Loyal Boyfriend Rides His Big-Cock Bull

I snuck my dominant bull into my boyfriend’s bed to ride his massive cock all night.

The apartment held a quiet it only found when Dominic was gone. Magnus stood in the entry with his keys biting his palm and watched Cyrus take the room in, the gray couch, the framed photos, the work boots by the door that were not his. Magnus was twenty-eight, the dedicated boyfriend, the one who answered fast and kept the place running while Dominic, thirty, chased deadlines on job sites in other cities. That care was real. So was the split underneath it. For months he had been cheating, meeting Cyrus whenever the hours opened, then coming home loose and lying about an extra shift.

Cyrus was thirty-two, broad through the chest, calm in a way that felt like weight. He was hung like a bull and knew it, a dominant who never had to raise his voice to take what was offered. He had come up the back stairs after dark, the way Magnus asked, phone silenced, steps kept quiet. He locked the door. The click settled low in Magnus's stomach.

"His flight lands tomorrow," Magnus said. "I checked twice. We have the whole night."

"You snuck me into his place." Cyrus dropped his jacket over a chair as if the furniture had been waiting on him. "Bold, for someone so loyal."

"I wanted it here." Magnus heard how thin he sounded and pushed through it. "Not a hotel. I want to give you my ass in this bed. I want to surrender it. All the way."

Cyrus looked at him, slow and hot, and Magnus's hole clenched around nothing. They had fucked enough times that Cyrus knew the hunger. He also knew Magnus still meant the loyalty he performed in daylight, the packed bags and the steady love. None of that had stopped the cheating. It had only proved there was a part of him no careful devotion could feed, a part that belonged to a bigger cock and had finally stopped pretending otherwise.

"Then no halfway," Cyrus said. "You ride me until you forget whose name is on the lease."

Magnus nodded. His palms were damp. He had been half-hard since he sent the address, picturing that massive cock opening him on sheets he had washed at dawn. The choice was already made.

"Bedroom's down the hall."

"Say it cleaner."

Magnus swallowed. "I'm surrendering my ass to you tonight. I want your cock so deep I feel you for days."

Cyrus's smile was small and satisfied. "Good. Show me where."

The bedroom lamp was already low and warm. Cyrus did not undress. He sat on the edge of the bed with his knees apart and crooked two fingers, and Magnus stepped between them, breathing too fast. Big hands settled on his hips, thumbs stroking just above his waistband, in no hurry to get him bare.

"Months of this," Cyrus said, almost soft. "Hotels. My truck. Every time I put this cock in you, you get worse. You text me from work. You get hard in the grocery aisle thinking about how I split you open. You call yourself dedicated, and you are. Dedicated to sneaking back for another ride. Tell me I'm wrong."

Heat climbed Magnus's throat. "You're not wrong."

"Say what you've turned into."

"Addicted." The word left him rough and felt like a lock opening. "I'm addicted to your cock. I think about it when I'm being good. I think about it when he kisses me goodnight. I crave it so bad I can't sleep. I don't want to stop. I don't even want to try."

Cyrus dragged a thumb along the hard ridge in Magnus's pants and hummed. "There you are. My loyal cheater. Faithful to everyone except the ass that already knows its owner."

Magnus swayed into the touch. "Please. I've needed it all week. I need you to take me."

"Strip."

He did it without tease and without pause. Shirt, pants, briefs, all of it shoved aside until he stood naked, cock flushed and wet at the tip, thighs tight, hole already aching. Cyrus looked his fill, then hauled him down into a kiss that had no politeness left in it. Mouths opened. Tongues slid and tangled. Magnus climbed into his lap and kissed him like he had been starving, fingers in his hair, grinding his bare cock against the thick denim bulge underneath. The shape of it was obscene. He whimpered into the kiss just from the size.

"Feel that," Cyrus said against his mouth. "That's what you've been cheating for. That's what's going to own this ass."

"Yes." Magnus kissed him again, messy and open, licking deep. "Please let me ride you. I want to sit on it. I want you to own me. Use my ass. Make it yours. I'll bounce on you until I can't talk straight. Please, Cyrus. Please fuck me like I belong to that cock."

Cyrus caught his lower lip in a soft claiming bite, then stood him back long enough to undress. When that cock swung free, Magnus went still. It was long, brutally thick, heavy enough to need a hand, the head broad and shining, veins ridged along the shaft. His mouth dried out. His hole fluttered, hungry for the stretch.

"On your knees," Cyrus said. "Get me wet. Then you ride."

Magnus dropped and took him in as far as his throat allowed, moaning around the weight of it, empty where he needed to be full.

"Enough," Cyrus said, rough now. "Up on the bed. Turn around. You're going to sit on every inch."

Magnus climbed onto the bed and turned his back, straddling Cyrus's thighs with his knees planted wide. Cyrus slicked himself with spit and a palm of lube from the bottle on the nightstand, then set the broad head against Magnus's hole and held it there. The pressure was immediate, blunt, huge.

"Sit."

Magnus sank. The head breached him in a slow burning push, and he groaned, fingers knotting in the blanket, ass spreading around a thickness that always felt impossible for the first few inches. He breathed, bore down, and took more. Cyrus's hands locked on his hips and the cock drove deeper, stretching him open inch by fat inch until he was seated flush, stuffed so full his belly felt tight and his own cock jerked untouched.

"Fuck," he gasped. "You're so big. I can feel you in my stomach."

"That's where you keep me. Now ride."

Magnus rose, rim clinging, then dropped and took the whole length in one desperate stroke. He found a rhythm fast, bouncing on that massive cock, ass slapping down against Cyrus's hips. Each drop punched a sound out of him. The stretch burned sweet and then went molten, his body remembering every stolen night and opening wider for the one cock it craved. He took it gladly, ass greedy, devoted to the pound. Sweat gathered at the small of his back. Cyrus gripped harder, fingers bruising, and thrust up to meet him, driving deep every time Magnus came down.

"Look at you," Cyrus said, strained and pleased. "Loyal boyfriend, sneaking his bull home to bounce on a cock that owns him. This ass was made for it."

"Yes," Magnus panted, riding harder, thighs burning. "Own it. Pound me. I want this cock. I want you to wreck me."

Cyrus planted his feet and fucked upward in hard thrusts, holding Magnus so he could only take it. The angle nailed his prostate on every stroke. His cock slapped his stomach, leaking, and his moans went high and broken. He ground down, rolling his hips, fucking himself on the length while Cyrus hammered up into him. Both of them worked his ass, owning the rhythm, owning the hole, neither of them gentle.

"I'm close," Cyrus growled. "First load, just like this. Don't stop."

"Give it to me. Cream my ass. I want it leaking while I ride."

Cyrus slammed up and held him down, buried to the root, and came with a rough shout. Heat flooded deep, pulse after pulse, a thick creampie pumping into him while the cock throbbed. Magnus cried out and kept moving, small desperate bounces, milking it, feeling the load smear hot around the shaft and slick his rim. Cyrus stayed iron-hard in the mess, breathing through his teeth, hands still clamped on his waist.

"Turn around. I want your face while I finish owning you."

Magnus lifted off with a wet sound, cum slicking his thighs, and swung a leg over to face him. He lined the swollen head up and sank in one greedy drop, crying out as the cock speared him open again, easier now, filthy with the first load. Facing Cyrus undid him. Sweat shone on that broad chest. Those eyes held him like property. Magnus braced on his shoulders and rode in earnest, long bouncing strokes that took every inch, ass clapping down, loud moans spilling out with no attempt to stay quiet.

The sheets twisted under Cyrus's heels. Magnus's thighs shook and he did not slow, chasing the thick drag, the way the first load squelched every time he dropped. Cyrus's grip bruised fresh color into his hips. Their stomachs slid, sweat-slick, and the smell of sex sat heavy in the warm lamp light. Magnus moaned into it, open and wrecked, and took the cock like it was the only thing he had ever been dedicated to.

"Louder," Cyrus said, thrusting up to meet every drop. "Let this place hear who you belong to."

Magnus moaned, shameless, voice cracking on his name. They found a brutal rhythm. Cyrus gripped his hips and pounded upward. Magnus slammed down and ground, both of them owning that hungry ass, both of them driving the fuck until skin slapped and cum squelched and nothing else mattered. Sweat ran down his chest. His cock bobbed, untouched and dripping. Every upward thrust mashed his prostate, a bright pressure coiling tight behind his balls.

"Both of us," Cyrus gritted. "You riding and me pounding. This hole is owned. Mine to flood. Yours to give. Say it."

"It's yours," Magnus sobbed, bouncing faster. "My ass is yours. Pound it. I'm still loyal out there and I still give you everything. You're so deep, you're hitting it, don't stop—"

Cyrus sat up, wrapped an arm around his waist, and fucked him from below in short savage thrusts, spreading one cheek to watch the rim stretch around his cock. Magnus rode through it, moaning loud, forehead pressed to his, mouths brushing, both of them lost in the pound. The pressure broke without a hand on him. Magnus came hands-free with a helpless shout, cock jerking, thick ropes striping Cyrus's stomach and chest. His ass clamped in rhythmic spasms, milking the cock still hammering his prostate, and the orgasm rolled through him so hard his vision whited.

Cyrus drove up through the clench. "Take another. I'm filling this owned ass until you can't hold it."

"Yes, cream me again," Magnus gasped, still shuddering, still riding. "I want both loads. Flood me."

Cyrus buried himself and came a second time, hips jerking, pumping another hot flood into the already soaked hole. Magnus felt the extra fullness, the throb, his ass fluttering around a cock that would not quit. The second creampie leaked around the shaft as Cyrus ground in those last inches and held him there, stuffed and shaking, owned to the core.

They stayed locked. Magnus didn't lift off. His thighs trembled and his forehead rested against Cyrus's, and the kiss, when it came, was deep and slow, all the frantic noise gone out of it. Tongues moved lazily. Cyrus's spent cock twitched inside him, still thick, still buried in the soaked, thoroughly owned heat of his ass, and every small pulse made Magnus shiver and kiss him harder.

Their breathing was loud in the quiet room. Sweat cooled on their chests. Cum leaked around the base and onto the sheets, a hot mess Magnus had no interest in stopping.

"You feel that?" Cyrus whispered against his mouth. "Still inside you. Still mine. This is the proof. You can be dedicated out there all you want. In here, you belong to this cock. You belong to your bull."

Magnus kissed him, shaky, honest. "I know," he whispered. "I belong to you. I gave you my ass and I meant it."

Cyrus held him down on the softening length and didn't answer again. The whispers faded. The room went still. Their mouths rested together, not speaking, and the only sound left was breath, slowing, shared, until even that seemed to thin into silence.
