Muscle Growth Fanfic Novels & Stories

I shut my eyes to calm myself down, but it only found its way of getting stronger. I could feel every single ounce of blood race through my veins. I could feel every hair on my skin standing out and even growing thicker... I felt myself growing in mass and in strength. I balled my hands into fists to control myself, but only ended up breaking my knuckles, and new sharp bones suddenly piercing my skin and growing out. I felt my teeth grow sharper, and my canines suddenly touching my lower lip. I felt myself growing crazy, and it was happening within seconds!

I cry out, gripping tightly onto him as my whole body shudders. His rhythm becomes feverish. His shoulders tense and his cheeks redden. His face is strained for a moment. Then he groans, long and hard, his muscles spasming beneath my fingers as he spills into me. Fuck.” **

Chapter 4: Eternal Knot The pack den thrummed with anticipation as the final confrontation with the Shadowfang pack loomed on the horizon. I stood at the center of it all, my body forever altered by the bonds I shared with Rylan, Thorne, and Kai. My curves felt more alive than ever—full breasts heavy and sensitive, hips wide and fertile, thighs thick and marked with their bites. The heat had peaked and begun to settle into a deep, abiding connection that made me stronger, sharper, more attuned to the pack’s rhythms. Yet the ache for their knots never fully faded; it simmered constantly, ready to ignite at their touch.

The anticipation of witnessing their growth and progress fills me with excitement. I anticipate that by the end of this grueling exercise, each and every one of them will be completely exhausted, collapsing from the sheer intensity of it. The thought of their bodies pushed to the brink, their muscles burning and their lungs gasping for air, brings a sense of fulfillment. It is in these moments of extreme physical exertion that true strength is forged.

He jumped back, grinning. “You’re slow today,” he teased. “Slow, am I?” I lunged forward, driving him back with a series of quick strikes. He blocked most of them, but I landed a solid hit to his ribs, making him gasp and stumble. He winced, but his grin didn’t falter. “Okay, maybe not that slow.” He groaned, and I grinned. "Who's an old man now?" I taunted, and he laughed. We continued our dance, a familiar rhythm. Axel had grown stronger than he was as a boy; it made me proud to see his progress. Each time his muscle bunched, I almost teased him again; his moves were calculated and precise.

“I especially like when you’re already inside me and you still push a finger or two in beside your cock. The burn… the way it forces me open even more while you’re fucking me. It makes me feel completely taken. I want to try something bigger than that eventually. Something that really stretches me until I can’t think.” I wrote every word carefully, the image already forming in my mind. “I like when you talk about breeding me, about filling me until it leaks out. Cum play. I like tasting it. I like feeling it inside me for hours after. I even like the idea of you using it as lube.” My handwriting stayed neat even though the words went straight through me. “What about bondage?” I asked.

His hand clutched my ass, pulling my body to him and digging his fingers deeper into my skin. My body began to shudder as I sat up and ground my clit into his stomach. His hand softly held my tit as the other held onto my hip, holding me down on his wonderful shaft that was still growing inside me. I felt like he was slicing me apart. I held myself down and squeezed all of the muscles I possibly could in my folds. A small growl came out of his mouth, but his body shook and his hips lurched forward like a wild beast.

He felt it growing thicker, the girth stretching his relaxed hole. Thrift was panting from behind him while Drift and Grift growled from both sides. Phoenix was moaning, thrusting back into them. Their cocks kept growing until he thought his ass would split. It was more than he could take, happening so fast he couldn't adjust to it. He felt the base of their cocks thickening. He started crying out in pain each time they thrust the last inches into him where their cocks had grown so fat. They mirrored each other's movements pulling their dicks all the way out, the head popping free, and thrusting hard all the way in. It felt like Phoenix was going to tear apart as their base was forced into h

“They’re called pecs. But boobie muscle is fun too. But you’re only three. You will grow into the body you’re meant to have, and if you want, when you’re older, I can help you become even stronger.” “And have biggew boobies?” I nodded, “but, it’s not just about getting big muscles. I like being strong so I can lift both of you and your mom.” Ripley blushed; I knew she was thinking about last night. That was fucking hot, thrusting inside of her against the wall. Yeah, I’m definitely trying that again. She seemed to love it too. Just another reason to have this body. Ripley loved it, and she loved what it could do.
