Muscle Growth Fanfiction Novels & Stories

The warmth of the water made my muscles feel relaxed, and before I knew it, I had spent half an hour inside. Looking in the mirror, I noticed that my arms and legs that had been spindly all my life, had started showing some signs of muscle growth due to the rigorous training routine. The bruises on my torso and upper thighs from the sharp kicks had begun to fade away, restoring my milky white skin to its original appearance to some extent. My curves had also started to appear fuller, after my waist and core had gained some definition. I was busy gazing at myself, analyzing the changes, but just when my eyes caught on my scar that stood out against my skin, I heard the sound of footsteps in t

Muscles burning in that beautiful way that reminds you you exist. I wasn’t thinking about mansions. Or blood. Or manipulation. Or nightmares with dark eyes and colder hands. I was thinking about gravity. And balance. And the life growing inside me. When I finally slowed, I leaned my forehead against the pole again, chest rising and falling. Sweat traced down my spine.My hand drifted to my belly. “You felt that?” I murmured softly. A small smile touched my mouth. “This was ours.” I didn’t know it yet. But somewhere deep in my bones, something shifted.

If I didn't know better, I'd swear that I had just awoken a beast inside of him. Fire was dancing in his eyes as he watched my breasts bounce up and down, and his biceps flexed again as he continued to struggle to break the invisible hold. Pressure started building inside of me, and at first I thought that it was from my own desire ready to be released, but then I realized that his dick was somehow growing inside of me, filling parts of me that had never been touched before .... well, he wasn't lying when he said he could control them. As I continued to ride Luke, my kegel muscles began to clench around his growing shaft, begging for him to somehow give me more.

My breath came in sharp gasps. Did I… just do that? I looked down at my hands, flexing my fingers. They didn’t feel different. But they were. I was. Lucas didn’t look at me. He was too busy fighting. “Your strength is growing,” he said. I swallowed hard. Another rogue came at me. This one snarled, baring long, sharp fangs. I didn’t have time to think. It lunged. I reacted. I grabbed it by the throat.

♡ Mia's pov ♡ I woke up with every muscle in my body aching. I blinked, my eyes trying to focus as I lift my head off a warm hard chest after feeling the soft thud of his heart under my cheek. I shifted slightly, unable to much seeing that his arm held my waist in a steel grip. The tips of his fingers brush just above my bottom and maybe it was intentional. I looked down, my heart leaping when my eyes fixed on his closed eyes that were framed by his long lashes. I never realized how long they are, but now I see how they brush just on top of his cheekbone.

The muscles of my jaw starting to ache. As I pulled my mouth back, all that extra saliva coated his cock from top to bottom. Red suffused my cheeks. I hurried to cover it with my hands. When my hands slipped and slid over his length, his body shuddered. "Grip harder." I tightened my fists. "Tighter." I clenched my hands into fists. The muscles of his legs quivered. "Now, pump it fast from bottom to top." His voice was more growl than tone. I jerked from the base of his dick all the way to the top. The extra lubrication allowing me to ease over the ridge of the head. My fists closed over the tip in a tight grip.

FINLEY Annalise is packed with alpha-female adrenaline. Xillon should stop taking it so easily on her. She needs more of a challenge. I can tell by the way her face scrunches up in annoyance from time to time. It’s only been a month since she gained her wolf. But she has already grown a couple of inches in height and her muscles have grown more taught. Damn, she’s gorgeous with sweat glistening off her sun-kissed skin. The sports bra and spandex workout shorts she has on leave little to the imagination. She’s stealthy as hell, too. Wish I could get a go at sparring with her.

“Nothing like that, I just played football when I was younger and guess the exercise regimen stuck. Also, I come from a long line of Alphas, so…” I was a little bit of a gym rat, I won’t lie. Most people stopped getting growth spurts once they passed the age of eighteen, but apparently, the human body grows in height until you reach twenty-four years of age, and so at the ripe old age of nineteen, I’d gone through my final and most painful growth spurt. It added several inches to my height, pushing me closer to goddamn seven feet than six. The only reason my sudden height and subsequent muscle mass didn’t scare my parents was that my maternal grandfather, who had passed away before I was bor

The child kicked violently, feeding on the energy, growing another inch in seconds. Damian followed with a roar, burying deep and flooding him—hot, endless pulses that leaked out around his cock, dripping down Alex’s thighs in luminescent trails. But the mutation refused to let them stop. Damian stayed hard, still buried, grinding slowly as aftershocks rolled through them.

God I dreamt about these muscles for days. Felix's grip tightened around my waist, his fingers digging into the flesh, asserting his control. “Always so dominant,” I mumbled and he pulled me closer. Felix's eyes darkened with desire and I leaned in, capturing his lips with, tasting myself on his mouth. As our tongues tangled together, my hands roamed his chest, tracing the contours of his muscular physique. I could feel cock getting harder, aching for my touch, and my wolf preened at the power I held over him.
