Sandra starts to become more muscular

    by: scriptboy Author IconMail Icon
“Nick! Pass the ball! Pass the ball over here!” Sandra shouted as she ran down the vast, empty soccer field.

Nick delivered a hard kick to the white- and-blue ball, making it roll towards his older sister. Sandra received the ball with her right foot and dribbled it towards the empty goal, when she was suddenly overcome by a faint dizziness. She stopped and rested her hands on her knees for a moment.

“Sandy! Something wrong?” Nick asked her.

“Feeling a little… Dizzy… Hang on…” she said quietly as she tried to shake it off. Sandra calmly sat down on the grass as she was overcome with some nauseousness as well, making her feel like she had to puke. Then, she was overcome by a weird cramp in her legs. What was going on?

While she sat there, her long legs began to bulge with muscle! Her quads suddenly grew thicker, deeper and much wider, like she had spent months or maybe even years doing nothing but heavy squats, lunges and leg extensions in the gym! Her quads inflated with large mounds of rock-hard muscle forming like large teardrops covered in thick veins! She could only gasp as she saw her muscles grow while she felt her strength increase at the same time.

While her quads were growing, so were her calves! Her long, thin leg muscles suddenly bulged into big, round soccer balls of thick muscle sticking out from the back of her legs, increasing her vertical leap dramatically. The feeling was amazing as Sandra sat there, watching her muscles grow and feeling her strength increase at the same time, causing her to moan loudly. Nick ran towards her, wondering if she was okay.

“What… What’s happening?” her brother wondered. “Are you feeling alright?”

“Here… help me up…” Sandra asked him.

He extended his hand and pulled her up. What he saw next was incredible. His sister had the biggest and most muscular legs he had ever seen in his life!

“Whoa! What happened to your legs?” he gasped.

But Sandra was not done growing, yet!
