Double Gains: A Female Muscle Growth Erotica

By HB Flynn

"Her muscles had grown more than he realized over the last few months, and thanks to the skin-tight nature of the spandex clinging to her body, it was incredibly noticeable to him. When she started doing her first set of bench presses, Graham couldn’t help but watch the way her muscles bulged and flexed through the fabric with the effort and strain of lifting the heavy bar.

“God, you’re so sexy,” Graham stated when her set was over. He had been holding back the urge the entire time she was lifting to reach down and grab hold of her bulging biceps, or run his hands over her breasts to feel the way her pecks were straining.

Lena was breathing a little heavy from the exertion, but smiled proudly at him as she sat up on the bench. “Thanks. And it’s all natural, too.”

Graham narrowed his eyes and leaned forward so that he was just a few inches away from Lena’s face. “You mean to tell me you don’t want me to make you big anymore?”

Lena stuck her tongue out at him, and Graham was suddenly struck by the memory of what that tongue could do. “Soon enough I won’t need you to.” Lena closed the distance between them and gave his lips a quick peck. “Let’s do my next set.”

Though she struggled to lift the last rep of her set, she managed it after a bit of a struggle. She collapsed her arms onto her belly as she lay on the bench, gasping. “I’m going to feel this tomorrow,” she stated.

Graham, who had been watching her intently as she performed her second set couldn’t help but shudder at her words. He could feel the straining within his jeans, and wanted so badly to let it out, and then rip down Lena’s tight little shorts..."

Who says all curses are bad?

Since she moved in with him, things have been going great with Graham and Lena. She's just as turned on by his mysterious ability to make her buff whenever they hook up as he is. With his life settling into a new normal, it seems like everything's going great.

Until Lena's bodybuilding friend starts poking around. She knows there's something up with Graham, and from how she keeps trying to seduce him, it seems like she wants in.

Chapter 1

A horn honked behind him, prompting three more honks from indiscriminate places in the line of traffic.

Graham sucked in a breath, and then blew it out angrily. He’d left work an hour ago, and had been stuck in traffic ever since. Traffic was the norm on the highway, but today it was particularly bad. There was the yearly arts festival happening in town that weekend, and the traffic was probably only the first in a long succession of annoyances he’d be dealing with whenever he left his house for the next three days.

In a perfect world, he’d just stay inside, but there were errands to run, groceries to buy, and not to mention he’d already agreed to go to the stupid street fair with his parents that weekend so they could finally meet his girlfriend, Lena.

The car in front of him picked up speed suddenly, and Graham elatedly followed suit, only to have to slam his breaks a moment later when the car in front of him stopped without warning. More honking sounded around him.

Between all the nonsense he’d been dealing with at work, (his company had decided to outsource some of their operations to a less than credible company overseas, forcing Graham to have to fix all the stuff they ruined), and now the seemingly unending traffic he was currently trapped in, he was ready to explode.

Was it really too much to ask for to just go home and relax after nine hours of working and cleaning up other people’s messes?

By the time he pulled into his garage, he was feeling more than a little grouchy, and was desperately looking forward to a nice, lazy evening.

The minute he stepped into the kitchen from the garage door, he was assaulted by a barrage of kisses from a very eager brunette.

Lena, he muttered in between her fervent kisses. He had to keep moving his head to avoid her. Come on, I had the worst—

Shush, she ordered, putting her hand over his mouth. Graham was about to push past her, but her free hand rose up and grabbed his, guiding it to her bicep, which he instinctually grasped and groped without even realizing it. See how small it is? she asked with a teasing pout. "I’ve been stuck like this all day, because you couldn’t be bothered to get up early enough to fuck me this morning." After placing his hand on her bicep, she’d started to snake her now free hand over his shoulder, down his chest, and then to his pants. She expertly unhooked the button of his trousers, and then dug her way through the fabric of his boxers to grasp his cock, which ached pleasantly at the feeling of her soft, warm fingers.

She started to rub him, a little awkwardly at first since he was still soft, but his body couldn’t help but respond to her touch, and soon she was jerking him off with the skill of a woman who was very, very familiar with what he liked.

Despite his grumpiness and frustration, he couldn’t help but relax his mind as his body tensed with the pleasure coursing through his cock at the steady, quick strokes.

You sure you don’t want this? Lena asked, her voice teasing and husky in his ear.

With a grunt, Graham grabbed her shoulder and pressed her downward. Lena, understanding his intentions, eagerly fell to her knees and pressed a quick kiss to the tip of his cock before encompassing the head in her warm, wet mouth. She progressed down his length slowly, inch by inch, giving each portion proper attention and assuring it was properly lubricated with her saliva before moving on. Then she was bobbing her head back and forth on his dick, while Graham held her by the hair and guided her motions.

Finally, he started to notice the familiar, yet still unbelievably arousing sight of her body transforming. The more she sucked his cock, the larger she got by the tiniest increments. It was so subtle, yet the signs were there. The cords of muscle in shoulders were growing thicker. Her arms, normally slender and smooth, were bulging along her triceps and biceps, expanding and firming up. Her tits and ass, which were usually pliable and soft, swelled up and broadened. Her forearms were starting to show the tiniest hint of long, sinewy striations.      Knowing very well by this point that it was much easier to feel the transformation than it was to see it, Graham released his hold on her wavy, light brown hair and moved to grab on to her biceps, which were raised up so that she could grab hold of his ass for purchase while she sucked him.

His body spasmed with a powerful orgasm as she flexed her muscles for him, allowing him to feel the way her expanding and stretching muscles had grown nice and hard from working him with her hand and mouth.

As familiar as she was with him and his body by this point, she was able to suck him vigorously just up to the point where his dick grew incredibly sensitive. Then, with her lips still tightly wrapped around him, she traveled up his length until she reached his head, and released him.

With a grin, she wiped the corner of her mouth with her thumb, where some of his cum had spilled out before she could swallow it. Welcome home, she said rising to her feet and wrapping her big, hard arms around him so she could bury her face in his chest. Graham lazily hugged her back and allowed himself to lean more heavily into her, enjoying the sensation of being supported by her enhanced strength. All frustration he’d been feeling when he came through the door was now forgotten as he basked in his post-orgasmic buzz.

A moment later, a ding sounded from the oven. Lena perked up and released her hold on him. Pizza’s done, she announced, hurrying over to turn off the annoying oven alarm. It’s frozen, obviously, Lena explained as she grabbed an oven mitt that was resting on the counter and opened the oven door. Graham had learned early on that Lena was not a talented cook, nor did she claim to be, and they had both agreed that she shouldn’t subject them to terrible, homecooked meals anymore.

Realizing he was still wearing his shoes, he leaned over to untie and remove them. He breathed in the smell of the pizza, and looked around his house.

It had been almost two months since Lena had moved in, and surprisingly, Graham had no complaints at all. Lena, out of misplaced guilt for being what she perceived to be a burden on him, had been the most considerate roommate he’d ever had. If it weren’t for her presence and the few belongings she kept out, he wouldn’t even know she was living there.

Of course, he didn’t treat her like his live-in maid, but every day when he left work, he came home to a clean home, and more often than not, a dinner of some sort, whether it was a frozen pizza, take out, or the occasional boxed pasta. As far as he was concerned, it was a pretty good deal. Additionally, he felt even closer to Lena, and it seemed like they were both very comfortable with their relationship. Though most people said that living together caused more problems, he felt more secure than ever.

Lena, of course, was desperate to find a job, and had been applying to anything she thought was worth a try.

She worked a few shifts at a diner waiting tables every week just to help earn a little money in the interim, but she still felt bad about how little she could contribute financially.

Just the day before, she’d gotten back from an interview for a job at a local charitable organization, but had been told she didn’t have enough experience.

She kept quiet about it, but Graham could tell it was starting to weigh on her self-esteem.

After she took the pizza out, she sliced and plated it for the two of them.

Graham headed over to the living room where he was about to plop down onto the welcoming cushions, but Lena stopped him. Wait! she cried, placing the plates down on the coffee table and rushing over before Graham could sit down. I dropped an earring under the couch earlier, she explained. Crouching down, she grabbed the bottom of the couch and with a huff, lifted
