Courtney 4

Courtney was frustrated. Even though she tipped the scales at a mighty 175lbs, equaling my weight, she’d hit a plateau. No matter what she did, she couldn’t seem to gain the mass she truly wanted.

Then she met a guy at the gym. He saw her pumping iron, and figured she was hard core enough to be interested in making the purchase. It didn't take much convincing.

Courtney asked me into the bedroom that night. She was wearing spandex briefs, stretched tight over thick blocky glutes. She was topless, as she always was now when at home. I could see the toaster-sized blocks of her chest and my cock twitched.

"I want you to inject me hun."

"I don't know Court, is this stuff safe?"

"I need this, honey. I need this to get bigger," she replied, her eyes begging like an addict looking for a fix.

"But what are the side effects?" I asked reluctantly.

She gave me a tender look. "That's sweet, hun," then her face went hard as stone, "but I want *more* muscle, more strength. I'm wanna be HUGE, and this is what I need to do it!”

Her face softened, and she gave me a seductive bedroom-eye look. “Besides, don’t don't you want to see me get bigger, baby?"

Then she flexed her thick, vein-covered bicep.

Damn, she was hot. And I did want to see her get bigger. So I did it, I shot her up.

“Oh, man,” Courtney said a few minutes later, “Is it hot in here?”

I shrugged, taking in my wife’s muscular form as veins started inflating all around her body.

“Wow… I feel like I have so much energy,” she said, flexing her pecs and looking at her reflection in the mirror.

“Shit, babe,” she said, eyeing the growing wet spot on her briefs. “I’m horny!”

My cock was already hard and ready for action. Which was good, because Courtney’s pussy was already sopping wet and her sex drive was roaring. She practically tackled me, mounted me, and power-fucked me again and again. I did my best to hold her angular, muscled hips as she grunted and thrusted over and over, orgasming once, then again, then again. She kept fucking me for as long as I could stay hard.

When she finally got up, I collapsed into the bed, worn out. But Courtney wasn’t done yet.

“Unngh,” she moaned, lewdly rubbing her clit. Did it seem bigger than before? Maybe I was just imagining it, but it was a thick red knob that looked firm and erect even after all that fucking.

“I’m still horny, baby,” she said. Then she cupped her pecs with one hand while she rubbed her clit with the other. Her eyes rolled back into her head as she orgasmed yet again. Then she reached over and grabbed a long, veined dildo. She wet it with her own spit and then shoved it into her pussy with a gasp.

“Ohh yesss…” she moaned as she slammed her hips forward and worked the dildo in and out, over and over, for ten minutes straight, bringing herself to another shuddering orgasm. I marveled at the cabled muscles of her torso, so cut and pronounced, like cords of rippling bulges all up and down her abdomen. Damn, she was sexy.

When she was finally finished, she stood. “Well, that was nice, but now it’s time for a workout.”

I was amazed. I could barely move, exhausted, and Courtney was going to head to the gym for an hours-long bout of tortuous weight lifting. I guess that injection really was effective.

“Alright, babe. See you later tonight!” Courtney said with a smile and left.
