Charlie, a fifteen-year-old boy, lay sprawled on his bed, staring at the ceiling. The scent of his golden retriever, Lucky, filled the room. It was their usual Friday night routine: his parents were out, and he would have sex with Lucky as he had countless times before. He reached down to stroke the dog, feeling the warmth of his fur against his skin. His fingers traced the outline of Lucky’s muscular haunches, moving higher until they reached his thick, erect cock.
Lucky whined softly, his tail thumping against the bed. Charlie grinned, pushing himself up onto his elbows. He positioned himself on his knees, Lucky’s hind legs straddling his shoulders. The dog’s weight pinned him down, their bodies pressed tightly together. With a practiced motion, Charlie guided Lucky’s cock to his entrance, feeling the familiar head nudge against his anus. He bit his lip, breathing heavily as he relaxed, letting Lucky take control.
The sensation of being filled by Lucky was overwhelming, as always. Charlie threw his head back, arching his spine, his hands digging into the soft fur at Lucky’s shoulders. The dog’s powerful thrusts drove him deeper, harder, each movement sending waves of pleasure through his body. He could feel Lucky’s hot breath on his neck, the soft whimpers that escaped his throat with each thrust.
Time seemed to stand still as they lost themselves in the rhythm of their passion. Charlie’s mind drifted, consumed by the sensations, the feel of Lucky’s cock sliding in and out of him, the taste of his fur on his tongue. He could feel himself getting closer, the familiar tightening in his gut telling him he was about to cum. He reached down, grasping Lucky’s hips, urging him on, needing to feel the release.
Lucky growled low in his throat, his movements becoming more frantic as he sensed Charlie’s impending orgasm. His muscles tensed, and with a powerful thrust, he drove himself deep inside Charlie, filling him completely. Charlie cried out, his body shuddering as wave after wave of pleasure washed over him. He clung to Lucky, feeling their bodies quiver together in shared ecstasy.
As they came down from their shared high, Charlie became aware of a new sensation: he was knotted. Lucky had never managed to knot him before, but tonight was different. There was no way he was going to be able to pull out. He looked up at Lucky, their chests heaving together, and felt a pang of fear mixed with arousal. He couldn’t help but wonder how he was going to explain this to his parents, let alone deal with the aftermath of being knotted by his own dog.
Before he could dwell on it any further, he heard a click from the door. His heart stopped as he recognized the sound: it was his older brother, Liam. Charlie froze, feeling a wave of panic wash over him. He knew that Liam had always suspected something was going on between him and Lucky, but he never imagined he would barge into his room while he was in the middle of it.
Liam walked over to the bed, a smirk on his face. “Well, well, well,” he drawled. “Looks like little brother’s been a very bad boy.” He glanced down at the knot in Charlie’s ass, and then back up at him. “I always knew you had a thing for our family dog.”
Charlie’s face burned with shame and anger. He struggled against Lucky, trying to push him off, but it was no use. He felt helpless and exposed, trapped in this horrifying situation. “Liam, please,” he whimpered, his voice barely more than a whisper. “Don’t tell Mom and Dad.”
Liam chuckled darkly, stepping closer to the bed. “Oh, I think they already have their suspicions,” he said, his voice dripping with sarcasm. “But don’t worry, little brother. I won’t ruin your fun.” He reached out and roughly grabbed a fistful of Charlie’s hair, yanking his head back painfully. “Just remember who your real master is.”
As Liam spoke, Lucky’s cock began to twitch inside Charlie, and then, with a final thrust, he came. Charlie felt the hot liquid spurt deep inside him, filling him even further. He gasped in pain and pleasure, his eyes wide with shock and arousal. He couldn’t believe what was happening, but there was no denying the sensations coursing through his body.
Liam laughed cruelly, amused by his brother’s obvious torment. “You know, I always thought you were a bit of a freak, Charlie. But I never imagined you’d take it this far. You’re my little pet now, aren’t you?” He squeezed Charlie’s cock hard, forcing him to look up at him. “You’re going to do whatever I say, whenever I say it.”
Charlie whimpered, feeling helpless and humiliated. He couldn’t believe this was actually happening to him. He glanced down at Lucky, who was still inside him, and felt a mixture of shame and arousal. A part of him wanted Liam to leave them alone, but another part was addicted to the sensation of being used by his family dog.
As if reading his mind, Liam gave him a wicked grin. “Oh, don’t worry, little brother. You’re not done yet.” He grabbed a handful of Lucky’s fur, pulling him roughly from Charlie’s body. There was a tearing sound as Lucky’s knot finally came free, leaving Charlie feeling empty and exposed. He winced in pain, tears streaming down his face.
Liam thrust himself into Charlie, burying his cock deep inside him. It hurt, but it felt so good at the same time. He could feel Lucky’s warm breath on his neck as the dog knelt beside the bed, watching them intently. Liam began to move roughly, his hips slamming against Charlie’s as he fucked him hard and fast. The bed creaked beneath them, the headboard hitting the wall with each powerful thrust.
Charlie arched his back, moaning in pleasure as Liam’s cock stretched him wide. He could feel the head of Liam’s cock brushing against something deep inside him, and it sent waves of pleasure coursing through his body. He clutched at the sheets, his knuckles white with the effort to remain still.
Liam smiled down at him, his expression softening. “That’s it, little brother,” he whispered, his voice thick with desire. “Let go. Give in to it.” He began to move faster, his hips slamming into Charlie’s over and over again. The bed creaked beneath them, and the headboard thudded against the wall, but it only seemed to add to the intensity of their lovemaking.
Charlie threw his head back, moaning as Liam’s cock thrust deep inside him. He felt so connected to his brother at that moment, their bodies moving in perfect harmony. The tension between them, the taboo nature of their relationship, only seemed to heighten the pleasure they both derived from their lovemaking.
As Liam reached his climax, his hips bucked violently, and he cried out in release, filling Charlie with his seed. Charlie could feel the hot liquid spilling into him, merging with his own essence, and he couldn’t help but arch his back in ecstasy. His own orgasm followed soon after, his body shuddering as he spilled his load into his mouth.
They collapsed together onto the bed, breathing heavily. For a moment, they simply held each other, the silence broken only by their ragged breathing. It was almost as if they were any other couple, sharing a tender moment after an intense night together. But they both knew that wasn’t the case. They were brothers, and they had just shared something that went beyond anything society deemed acceptable….
