Muscle Growth Fanfiction Novels & Stories

“Yes. It’s a storage ring and something more. HAHAHA! I’m sure you will enjoy its benefits, Tiny Slim. Treasure it well.” Maru said to the fat boy who loomed above him. He wished that he would one day, grow up to be tall and muscled like what he saw of those soldiers’ physiques earlier. Of course he could have taken another form and grown exactly as he envisioned with the help of Madame Ais. But that was different. It was not his own body and did not like the appearance of falsity it represented. Maru sighed and comforted himself. He has time. No need to be so impatient about it.

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.

Others fall to the sheet, staining dark circles where they land. His strokes grow ever more vigorous, ever more forceful. His breathing is heavier. Inside me, muscle thrumms, a low throb which, all the while, builds and grows, my twitching pussy dancing around my Master's shaft, dragging a moan from my throat. "Oh, God…"

I sighed at the unfolding bliss, knowing I would probably get to fill her with my potent sperm within the hour. Her nipples were no longer subject to the rules of mortals, and they grew an inch longer and much thicker against my white chest muscles. Her thick savage lips kissed my face and neck, and she let the bottoms of her feet become anchored by the hard ground below. She now pumped up and down over top of me, her large mutated nipples digging sensually into my flesh as a sexy hair began to grow over her back and bum. It was the same lovely chestnut brown as the silky, curly strands now framing her perfect but contorting face.

* Zeina * The days bled into one another, a haze of stillness and swelling breath. My belly had grown, rounder, heavier, a moon full of weight and mystery pressing against my skin. The movement inside had grown more frequent too, no longer flutters or whispers, but real shifts of muscle and presence. He was growing. Strong. Unrelenting. Just like his father. But even as my strength returned in quiet increments, bone knitting, magic crawling back into my veins like timid light, I felt something else begin to falter.

My bones stretched and contorted, snapping into place as they took on a new form. Muscles tightened, expanding over the reshaped skeleton. Thick strands of fur burst from my skin, each follicle igniting like a thousand needles piercing me at once. My canines elongated, sharpening into deadly points, my jaw aching as it widened unnaturally. Sharp claws pushed through my fingers, cutting through it. Through the agony, I fought to hold onto a single thought—I wasn't the weak Redwood girl they all believed me to be—the one they had mocked and underestimated.

I tried to sound playful, but couldn't help the sadness I felt thinking about the future. “Is that a challenge?” He took the stairs almost two at a time. “I doubt you will ever get so big that I wouldn't be able to carry you. What are my muscles made of if not for this?” He placed a kiss on my forehead. “Don't worry, I will always carry you. Even if you get so big, I can do it.” “Won't I be ugly if I get so big?” I closed my eyes, so I wouldn't be able to see his emotions, to see him lie he would always see my beauty.

And the vision of her luscious, young body when as she fingered her bare pussy, goading him to stroke hard and cover her beautiful skin with his hot cream. But he had to push those thoughts out of his mind as his cock began to grow. They were moments they could always treasure. They could always love each other more than anyone else in their lives would ever know. Someday, Angel would probably get married, and Roman himself didn't dismiss the idea of getting married again himself. But they would always have something more. Something no one else could ever touch, and he didn't know how he could love his daughter more.

We had the make up as soon as we wore our dresses and we were done. Our finals had ended last week. Atlast we were free now. "You look beautiful." Blake said when he saw me. I gave him a cheeky smile. "You don't look that bad either." I told him. Blake has been growning hotter as time passes by. He had developed more muscle and looked even hotter then before. I feel so blessed to have a boyfriend like him. Yes, we have had our own little fights but our bond grew stronger with time. I loved him so much. I loved him more than anything in this world.

A growl rumbled through his chest, and he pulled away and said, “I don’t know if this is a good idea in your state.” I began to chuckle before I said, “I pulled a muscle. There isn’t anything wrong with my pussy that is craving for your attention right now.” Desire then flickered in his eyes and I knew he wanted me just as badly as I wanted him. His lips then moved back to mine as his hand moved down my body and to my throbbing pussy that so wanted his attention. As his finger dipped between my folds and my juices coated his finger another growl rumbled in his chest as he pulled away from the kiss and whispered, ‘Always so wet for me baby.”
