Brad opened the door and looked down at his girlfriend Jess. Standing at only 4 foot 11, her body was anything but petite. A former national level gymnast, she had quit the fast track to the Olympics for several reasons. One was that she would have to move away from her friends and family to train with the best coaches. The second one was that she had developed a generous bust that the coaches were convinced would only get in the way, although Jess had smoothly adjusted her balance to compensate. And the third was that she enjoyed spending more time in the weight room that on the apparatuses. Her body was filled with top level fitness sized muscles that she proudly displayed for everyone at school. And Brad was the boy who enjoyed her muscles the most.

Brad flushed at the sight of Jess with her long blonde hair tied neatly in a ponytail, her deep blue eyes, sparkling white teeth and beautiful girl next door features. She placed her hand up on the door frame and tensed her arm, giggling as Brad watched her perfect baseball bicep leap to attention. She had worn an athletic top that seemed a bit small, as her pectorals thrust her C sized breasts forward and the tit flesh was nearly spilling over the top and sides. Her six pack abs were clearly evident, even relaxed. Her thong straps were showing above her jean shorts, showcasing her muscular, curvy legs from her thick thighs to her bulging calves. With Brad still staring at the awesome sight in front of him, Jess cleared her throat, clearly amused by his reaction.

“So are you going to let me in or what?”

Brad nodded and Jess smoothly stepped forward, dropping her flip flops by the door.

“So what’s this about Amanda and some gun?”

As Brad walked her up to his room and explained the recent events, Jess gave him a skeptical look. “And now she’s as muscular as you?”

As Brad pulled his shirt off, he looked over his own stocky frame. “Yeah, at least.”

Jess shimmied out of her jeans. “So what would you think if I grew as muscular as you?”

Brad flushed again and his already building erection jumped. Jess giggled. They both knew the answer to that one. As they climbed into bed, Jess turned to Brad.

“Good thing your parents are out of town for the week-end, huh.”

Brad smiled. “Yeah.”

Amanda and Randy were making out on the same bench Amanda had pressed the 200 pounds only moments ago. He could hardly believe how big and how hard Amanda’s muscles were. He had to control himself from going into some kind of muscle lust. Amanda was breathing heavily. Never had a boy enjoyed her body so much. She knew she was now as strong as Randy, maybe stronger. And he clearly had no problem with that fact. Her muscles were a bit bigger and definitely more defined and better shaped. She certainly didn’t have to worry about who was in control. As Amanda struggled to get her top off, Randy had already dropped his shorts and was pulling on Amanda’s equally tight jeans. Amanda laid back on the bench, hoping Randy could hold himself long enough for her.

As Brad let out a post coital sigh, Jess was feeling something different. As though a small fire was building within her. Her muscles soon felt as though she had just finished a long work out and she let out a painful sigh. Brad looked down, figuring it was his weight on her that was causing her discomfort. He brought his arms in and placed his hands on either side of Jess, looking to push himself off. But then Jess smiled at him. A warm rush now built within her and Brad noticed that her body seemed to harden below him. Jess brought her own hands down toward Brad’s hips and licked her lips.

“Either you’ve just lost a whole lot of weight.”

Brad let out a surprised “oh” as Jess gripped his sides, extended her arms and in one smooth movement lifted Brad’s 175 pound above her. His legs and arms dangled as his eyes widened and Jess giggled.

“Or I’ve just become a LOT stronger!”

Randy pulled himself off Amanda and was sitting at the edge of the bench, staring at her magnificently muscled body. Her large breasts nearly obscured his view of her pretty face with her long dark hair, soft green eyes and clean features. He placed his hands on Amanda’s thick muscular thighs that were straddling the bench and smiled. Amanda’s expression was more curious as a familiar, but somehow slightly different feeling filled her body. She glanced over toward the gun, wondering if Randy had shot her with it, but it was too far away. As the feeling built and a warm rush flooded her body, Randy’s expression changed also as he felt Amanda’s thighs become harder and more defined below his probing hands. He squeezed tighter and was shocked to find that her muscles now felt like steel. Barely feeling Randy's hard squeeze, Amanda reached up, gripping the bar for support. Before she knew it, she had pulled the weight off the rack and was holding it effortlessly. Both of them looked up at the bar with surprise. The look soon changed to a pleasurable realization for Amanda as she glanced toward Randy.

“Uh Randy, I think I’ve figured out what the gun did to you.”

Randy leaned back and his jaw dropped as Amanda cranked out several repetitions with amazing ease and placed the bar back on the rack with a clang.

“It seems you just made me the strongest girl in the world!”
