Collaborative sex stories let us write the plot together
(Medical Experiments, continued by Zmeister54...)
You see that your hands are glowing a little bit. “What the hell?”
“I don’t think that’s supposed to happen,” Nurse Jenny says as she touches your hand. But the light goes into her and fades. And then…
“Eep!” Jenny yells loudly in surprise. What feels like a jolt of electricity suddenly shoots up her spine, forcing the her to stand up straight!
Warmth coats her back, which grows new sinews in the blink of an eye. Various lumps of muscle begin to flank her spine as they grow larger in size, while also becoming more defined. Jenny doesn’t know why — she really doesn’t — but somehow she feels them expand, widening in tandem with her lats that flare out. The growth affects them rather heavily, apparently, seeing as her torso starts to accommodate her improved, corded back.
Traps desperately try to touch her earlobes, and thus thicken exponentially. They grow alongside Jenny’s delts; pounds upon pounds of muscle mass connected to each other, enlarged as if by magic. It doesn’t take long before the nurse possesses a back wide enough to make it rather awkward to fit through small spaces. However, despite her size increasing bit by bit, so do the details of her muscles improve. Her blouse clings tightly to the vast expanse of sinews, granting you a perfect view of her majestic muscle tapestry.
And if her traps and delts keep engorging like this, then she’s gonna have one hell of a bullneck soon enough!
“This feels so… weird!” Jenny gasps. Veins throb across her mighty physique, spreading to new places at an almost alarming rate, so they can better fuel the rapidly-becoming-heavyweight nurse’s body. “Yet, not in a bad way? It’s just- ah!”
She almost loses her footing as her legs visibly tremble. Thighs thicken with each heartbeat, quads and hamstrings developing in synchrony. Jenny places both hands on them, fingers grasping and digging into the deepening crevices that split the muscles apart, barely staying upright. Sounds she only makes underneath the sheets escape her plump lips as her legs transform into sturdy pillars.
Jenny’s gaze falls on her forearm, noticing how the veins there are almost bloated; each furiously pumping nutrients into hungry muscles. The thickness of her arms is becoming more and more apparent. Sweat pours down the sides of her head, droplets dropping into her muscular cleavage, right in between two expanding slabs of beef, as her arms bulging with rippling muscle that would make female bodybuilders envious. Hell, males too!
Her breathing turns raspy as the growth reaches its peak. “Ah- oooh!”
Every muscle in her body suddenly spasms and almost explodes to new proportions. It’s so sudden, so quick, that Jenny’s willpower is all that’s keeping her conscious through the whole ordeal.
She scowls and flexes her physique with an animalistic fervorr. Skin bulging, ripped muscle mass glistening in the light. Her abs become as solid as steel. Calves bloat with a perfect teardrop shape to them. Glutes as round as soccer balls, yet far firmer than any flimsy material they would have been made out of. A large blue vein appears on top of her prominent bicep peak, which reaches a magnificent height when fully flexed.
“Raargh!”
The bellowing nurse roars her satisfaction. A sense of power unlike anything she’s ever felt before fills her mind. With her muscles pumped to the max, she knows she is strong — more powerful than any man.
Finally, the growing stops, allowing Nurse Jenny to catch her breath. The nurse flexes her enlarged bicep, smiling at the sight of it. “Oh, that’s beautiful.”
She then notices you looking at her, your mouth wide open and your cock bulging like crazy. She looks at you and smiles.
“So…” She says, flexing her arms. “Wanna feel them?”
