Alex 1

Alex had always been the skinny little sister. Even at 18 years old, she had thin legs, thin arms, and a flat chest. Ever since she was a kid, she had looked up to her three-year older brother Ken, who was a fairly athletic kid about 5’8” tall and 170 lbs. For Alex that meant literally, because she was only 5’4” and 110 lbs.

Alex would always be a little jealous seeing Ken dating the cheerleaders in high school. All the girls he dated seemed to have big boobs and curves, which Alex definitely never had. But one thing she could always count on was that Ken never stayed with them long. Even now, at 21 years of age, he had never had a steady girlfriend, and rarely went out with the same girl more than once or twice. Even though, by the standards of most of the population, the women he was dating were hot, Ken never seemed satisfied.

Alex asked him about it once and Ken just shrugged his shoulders. It was like he didn’t even know what he wanted. But one night, Alex made a discovery. Ken was flipping through the channels on the TV when a women’s bodybuilding competition was being televised. Ken let the channel linger just a little too long, and Alex noticed his eyes widen and his pelvis shift in the couch as he ogled the muscular women.

Intrigued, Alex said, “What do you think of these muscle-chicks?”

Ken shrugged and quickly changed the channel. “I dunno. It’s a little weird.”

But Alex could tell by the tone of his voice that he was embarrassed. He liked it. Maybe he didn’t know he liked it, or maybe he was in denial. But it explained so much about his dating habits. Of course these big-busted bimbos would never satisfy him if he was into muscle. Alex resolved then and there to help Ken come to terms with it.

She started going to the gym every day, and looked up fitness regimens at night. She was surprised that her body toned up quickly, and she started developing some muscle definition in her arms and legs after just two weeks of lifting. She supposed she had good fat-burning genetics, and her muscles responded well to the exercise. But she wasn’t really gaining much size.

One day she saw a huge, muscular man curling 65lb dumbbells at the gym. She walked up to him and struck up a conversation, asking him about his fitness routine. At first he brushed her off, but Alex was persistent.

“Look, part of it is genetics,” said Biff. “Part of it is the, ahem, supplements you take.”

“What supplements?” Alex asked curiously.

Biff shrugged his big, muscular shoulders. “It won’t matter for you. Look at you, you’re a skinny girl. Even if you juice up like me, you’ll never look like this,” he said arrogantly as he flexed up a muscular bicep.

“We’ll see about that,” Alex fumed.

Alex, being a child of the internet age, knew she could get anything she needed online. The internet made obtaining chemical assistance easier than she had imagined. She did the research and got the protein powders, supplements, and most of all, the steroids that were going to help her build the body that would capture her brother’s attention.

She started right away. In the first week, she felt like she had so much more energy during her workouts that she might explode. She hit new maxes in every lift, from squats to bench press to preacher curls. Within two weeks, the scale said she had gained ten pounds, and she could tell it was all muscle. These quick results only made her push harder, lifting heavier and eating bigger.

At night, Alex began her attempts to get Ken to notice her. She left her whey protein and supplements on the counter, hoping he would ask about them. She would put bodybuilding competitions on the TV whenever she had the remote. One night, Ken walked in, looked at the counter, and asked, “What’s all this?”

“Just some whey protein and creatine supplements, “ Alex remarked excitedly. “I’m trying to bulk up, you know?”

Ken’s eyes widened as Alex flexed her arm and a bicep the size of a lemon popped up.

“Really? Since when?” Ken asked, pointedly not saying anything about her impressive new musculature.

“Well to be honest, a few weeks ago when you were flipping through the channels and landed on a bodybuilding contest, I got inspired. I decided I’d give it a try,” Alex said with a seductive smile.

Ken blinked. His face went red, and he left the room. Alex knew from his embarrassment that she must have scored a hit. Who knows, maybe he was going up to his room to whack off? She snuck up the stairs and stood by his closed door. Then she heard it - the thwack, thwack, thwack sound of Ken beating his meat.

She felt thrilled, and suddenly very horny. Her pussy was practically gushing, so she went to her room and did what she knew Ken was doing. She imagined herself growing bigger biceps, bigger thighs, and she imagined Ken watching her flex. She got so turned on that she practically gushed juices in a mighty orgasm.

Afterward, she fell asleep, and had a very interesting dream. She was standing naked, staring into the mirror, and flexing. She felt an orgasmic delight as she flexed and watched her biceps slowly bulge and grow. She looked down and flexed her quads and watched them bloat and swell with mass. She looked in the mirror and flexed her flat chest and watched as muscles bulged up beneath her skin. Her pecs undulated with growing mass, creating a defined cleft. She moaned and stroked her now wet, protruding clit, the sight of her own growing mass as erotic as she had ever imagined.

In her dream she was screaming, “Yes, yes! More, more!” as her muscles vibrated and shook. She came like a torrent, then she woke up.

Sweat had pooled on her brow, and she had creamed her panties. Unfortunately, her body was still the same, though slightly more defined thanks to her new workout regimen. Her lithe body now had a defined six pack, and she ran her hands along it and felt the bumpy ridges. She might not have huge, freaky muscles, but she still enjoyed the feel of the solid definition of her abs. Her other arm felt her small but well-defined tricep. She squeezed and felt satisfaction at its firmness.

Feeling up her own small but defined muscles was turning Alex on again. She reached down beneath her panties and started stroking and fingering her clit, pushing and pulling on it as she thought about what it might be like to have bigger, thicker biceps, rippling pecs, bulging thighs. Oh god, it made her so horny, just the idea of being bigger, thicker, wider…

“More…” she whispered, feeling her climax building as she imagined big bulbous traps swallowing her head.

“More!” she moaned as she stroked harder and faster, imagining lats growing wider than her elbows, and bulging rows of abdominal muscles protruding from her mid-section.

“MORE!” she cried, her imagination running wild with images of muscles surging with craggy peaks from her freakishly hulking body. Her pussy spasmed and squirted as she came harder than she ever had before.

“Wow,” she sighed. “I didn’t realize just how crazy my muscle fetish could go!” It felt a little weird, and a little dirty, but she decided that she liked it.
