1.) Shortly After Chapter 3

Helen is scarily strong now, and you’re certain that given enough time she could accomplish this feat… but to lift a tree already? Whether or not she can do it doesn’t matter. Her fingers have already dug into the wood, and she’s pulling with all of her might. From where you sit, you can see the muscles in her back flare with newfound life; they bulge so much that it’s frightening to behold.

The ground beneath Helen trembles and her feet sink a few inches into the ground, which will no doubt leave a crater once she’s finished with her task. She draws even more sunlight into her fold, those incredible muscles of her shifting and growing even further; her legs and arms lengthen another inch – perhaps to grant her better leverage for the task at hand.

Then you hear it: the undeniable sound of wood creaking. Slowly but surely, somehow, Helen is upending the tree. You see its roots stubbornly cling to the earth beneath her; those closest to the trunk are unearthed – unduly removed from their resting place. Upon closer examination, you see that Helen’s fingers are digging more deeply into her target’s core. If she were to let go now, there would be a deep imprint of her grip left behind.

A loud, beautiful grunt emanates from her powerful throat, filling the air. More creaking follows, and the tree ascends another inch; more roots follow, and you can see the outline of the rest come closer to the surface. The roots are like a vast labyrinthine spiderweb, and they grant a better scale of how difficult her task truly is. This is no straggler – the great tree had taken decades to grow to its proud height, and Helen threatens to utterly dominate it with power gained in a mere few hours.

Helen’s grunts of effort are now practically yells. She sounds like a character from a video game or anime gathering her strength – which ends up being true, as she somehow absorbs even more of the sun’s power – instantly growing even further as a result. Her glutes, hamstrings, and calves seem to be the focus of this power up – widening, thickening, and generally spilling out even further as a result; the tiny gap between her thighs tightens slightly – even less light pouring through; her calves jut out so menacingly that individual halves of her diamond-shaped muscles have their own splits and valleys of definition; her hamstrings now protrude out further than your own quadriceps do, and possess far more muscular detail than any of your limbs could ever hope to achieve.

And the power-up is working: the rest of the stubborn roots have emerged above the ground, disrupting the dirt and grass with them. The bulk of the tree is now multiple inches into the air. Much like your own experience with Helen, as the tree’s power wanes—losing its stability granted by the roots—hers steadily increases. You can’t help but find a sharp irony in how the three, which grew to its mighty size by photosynthesizing the sun’s energy, is now being overcome by a woman who seems to be doing much the same.

Momentum was already on Helen’s side, and without roots anchoring the tree, the tide has entirely turned. Helen now has the entirety of the great oak held above her head – but her strength wavers, and she has to place it on her brawny, rounded shoulders.

The tree is firmly on her back, but something is amiss – Helen isn’t standing steady. Her entire body is wavering, which is downright terrifying with a multi-ton weight bearing onto her. “Need help!” she yells.

“How can I possibly help?!”

“Think with your Johnson!” She replies.

You immediately understand. Without delay, you rush over to her, and as you close the gap, Helen’s new upgrades become more apparent. Her shoulders now look like a pair of small heads, between them lie a collection of traps so thick they threaten to entirely swallow her neck; the intrinsic smaller muscles of her back have developed beyond what you’ve seen on anatomy models; even her erector spinae has thickened, the individual bumps of bone protrude out more—a quick glance shows the same to be true of her elbows—doubtlessly a necessary improvement to accommodate her muscle and strength.

But there’s no time to gawk, despite your desires. You pivot in front of Helen, and focus the task at hand, quickly stroking yourself. Your dark sense of humor kicks in as you think about how humorous it is that this jerk off session is literally a matter of life and death. Still, you can’t distract yourself – Helen needs your help. In fact, now that you’re in such close proximity, if Helen falls here, the tree very well may end your life. Actually, Helen could very well survive such an injury, you on the other hand…

No time for that!

You think about how all you have to do is provide another power up, and Helen will be able to manage the tree with ease. The mere concept of your girlfriend having that much strength is enough motivation that the climax comes quickly and easily. A huge spurt squirts out, landing directly onto her exposed chest; you notice that it quickly seeps into her skin, and she lets out a groan of pleasure, and her entire body begins to quiver – presumably indicating she’s about to grow once again.

Despite this initial growth, you want to ensure that your girlfriend doesn’t die. To facilitate this, you carefully collect the rest of your discharge; which disgusts you slightly at first until you convince yourself that this is ‘magic lotion’ that will make Helen stronger. After collecting the lion’s share of your ejaculate, you close the distance, divvy your ambrosia between both hands, and bring them up to Helen’s arms.

You work the lotion into her shoulders and chest, careful to thoroughly explore the crevices of these regions to ensure Helen gets as much exposure as possible.

She has broken into a sweat, which causes her skin to radiate even more – especially in tandem with the mysterious sun’s light. Her muscles quickly drink in your gift, growing even mightier in the process. Helen’s deltoids have become so large that you can’t wrap your hand around them; her pecs are manifold times larger and denser than your own, despite still holding her perfect breasts; and her entire upper half has widened even further – encroaching on becoming twice as broad as yours.

“Legs! My legs need it too – losing balance!” She exclaims. “Foundation isn’t strong enough!”

You’re not sure if her claims are true, but this is no time for doubts or messing around. You quickly prepare to produce more, but find that you need more stimulation. With no time to spare, you move closer to Helen, crouch down a bit, and bring your member to Helen’s right leg. You manage to actually fit the entirety of your girth within the deep crevice of definition in the center of Helen’s thigh: the center of the teardrop; and you are thoroughly above-average in this category – further illustrating just how massive Helen’s trunks have become. Surrounded by the tremendous warmth and energy radiating from the leg, combined with a bit of manual stimulation as you hump a few times, you are thoroughly overwhelmed with sensation, and release once again.

Your offering is immediately absorbed into the mammoth fold of feminine power, and once again Helen groans with delight. “Get the other leg!” she demands – your work isn’t quite finished yet.

You withdraw from the makeshift sexual cavity of Helen’s left leg, and move over to her right. Despite having just released twice, you can already feel that you’re ready to give Helen even more power. Without any prompting, you rub yourself on top of that leg. Your mind considers that Helen was able to lift that tree, and now you’re about to give her a third release since then. The mere consideration of how powerful Helen may become is enough to coax you into another orgasm – which in turn spurs on a growth spurt for that leg.

Helen was already capable of uprooting and lifting this tree, and now she’s received three more blessings from you. Her mind acclimates to the sheer amount of power at her disposal, and she stands firm – still holding the tree above her head; if anything, it now looks somewhat easy for her to hold.

Her expression shifts from pained effort to extreme triumph, a massive grin is met with a hint of well-deserved arrogance. “May as well keep going since we’ve come this far, right?” She says before squatting down with the immense weight still on her back. Helen’s quadriceps bulge out even more – the gap between her thighs reduced to a mere pinprick. Slowly, Helen stands back up, and her legs lengthen again as she gains another inch of stature; the gap widens slightly. You are still taller than Helen, but the difference has been reduced to only a few inches. She descends again, sturdier and further in control of her motion. Another repetition confirms that even squatting the great oak has become comparatively easy for her.

Before long, Helen grows tired of squatting the tree. She places it on the ground, careful to not haphazardly toss it. Even with her might slowing it, the tree creates an almost deafening sound as it touches the ground. You feel a tinge of guilt as you stare at its once-majestic roots helplessly exposed to the air. Hopefully Helen keeps her feats of destruction to a comparatively small scale.

2.)

After crushing those rocks and discovering her levitation abilities, Helen’s confidence had been steadily surging; but now she’s leagues more self-assured. Her expression alone oozes certainty. She’s aware to the magnitude of the feat she just accomplished, and also knows her strength is still steadily increasing.

Helen lazily floats a couple feet into the air, and somehow manages to cross her outrageous legs – creating an unfathomable wall of feminine flesh in the process. Despite her muscular definition, there’s an exaggerated feminine shape to Helen’s figure and curvature; even the pose she is striking is exceedingly regal – like a budding goddess who knows nothing can hope to stop her.

“Well dear, now what?” She asks in a low, rich voice – slowly levitating towards you.

“What are you going to do with that?” You ask, pointing to the uprooted tree.

Helen shrugs. “At the very least, it’ll be a useful weight to continue my training.”

“Oh?”

Helen nods. She floats back over to the tree and lands next to its center. Next she bends down and places her hands on the now-log. You hear the wood creak and crunch as Helen’s fingers dig into it, her forearms bunching up even further. She lets out a loud grunt, and starts pulling the wood up with all of her might.

As the entire uprooted tree moves, the sheer extent of its size unsettles you. Despite her sheer muscular girth, Helen is still comparatively tiny next to it. You soon realize that Helen has dead lifted the tree; and now she’s performing repetitions with it. You can’t help but wonder how long until she’s able to lift the entire thing with a single arm. And to think that a few minutes ago you had to provide an emergency power up to prevent it from crushing her.

Unsurprisingly, each repetition seems to come more easily to Helen than the last. Her grunts grow quieter, and while it’s difficult to see with the makeshift weight in the way, her lats appear to be even wider. After the tenth dead lift, she places the tree back down on the ground, as if it were nothing to her.

Helen starts walking over towards you. “Whaddya say? Am I goddess status yet?”

You strike your chin a couple of times before replying, “Nah. More like a low level super.”

“LOW LEVEL?!” Helen yells, placing her hands on her hips in a no-nonsense fashion. If she wasn’t your girlfriend, and if you didn’t have years of experience bantering with her, you’d be afraid for your life.

“I mean… yeah. Even Ultraman would instantly obliterate you in a fight. You’ve got a ways to go.”

“Hmmph!” Helen takes a few strides towards you, intentionally slamming her feet on the ground, causing it to continue quaking. “How can you call yourself a comic fan without remembering that Ultraman would lose his powers under a sun like this?”

That is… a surprisingly great point. But still, “How do we know that this sun has the same properties as the one in Ultraman’s world? For all we know it could actually empower him even further.” You retort.

Helen squints a bit, “But, by your own logic, how do we know that he would be empowered by the sun at all in the first place?”

You ponder the thought experiment, trying to come up with an appropriate response, but fall short. “Touche.” You concede.

2.5)

Helen stands a few inches in front of you. You estimate that there’s only a 3 inch difference of height between you, though her posture and sheer presence effectively removes another inch. Her skin is so pristine and vibrant, as if it belongs to an idealized fictional character, rather than a living person. Helen’s hair, which was already bright blonde, draws ever closer to the sun’s radiance in color. In fact, staring directly at it for an extended period of time hurts your eyes.

“You know…” Helen starts – visibly concentrating, “If I try really hard… I can zoom my vision in. A lot.”

“Oh yeah…?” You ask, somewhat anxiously.

“Yeah.” Helen confirms, “I guess I can’t see at a molecular level or whatever, but maybe the uh… cellular? I dunno, I was never too good at that biology stuff.”

At least she isn’t randomly turning into a genius. “Well, what do you see?” You ask.

“I think your body and muscles are pretty normal. But…” She turns her attention to her own before smirking wildly, “Mine are… How to explain this… Well, it looks like I have this kind of energy emanating off of my cells, like they’re super-charged.” She says.

“Makes sense.”

“So babyface, tell me…” She preempts before bringing up her right arm and slowly tensing it. A massive ball of power rises, underneath it thick tendons fill the deep gap between her upper and lower arm.

“I… I dunno Helen. Maybe like 22 inches?”

“That’s all?” She asks with another huff. “Here, put your hand on my muscle.”

You comply. With your fingers on it, Helen extends her arm out again, and begins gathering sunlight as she tenses it. You can feel firsthand as the sunlight somehow moves through your fingers and directly enters Helen’s bicep; not an atom of it empowers you. You can feel the muscle somehow hardening even further, then it begins to grow – physically pushing your fingers apart a little in the process.

“Well, now what are they!?” She asks.

“I really don’t know Helen, I don’t have a measuring tape. But I’m guessing they grew another inch.” You explain.

“I hate being so weak!” She pouts.

“Weak!?”

Helen giggles before lightly grabbing your crotch. Despite all of the stimulation, it remains only at half-mast.

“I guess three times in such rapid succession during the tree incident was a bit much.” Helen says, “So you probably need a little more… motivation.” She floats up into the air until her crotch is directly level with your face. Helen nudges herself forward, “You know what to do.” She says.

You’ve serviced Helen before in the past, but to do so while she wields immense power, AND is floating in mid-air, is another experience entirely. Inches away from her thighs—each of which are thicker than your waist—the heat radiating off of them reminds you of the sheer amount of power at her command.

And her taste… that sweet honey from her ‘honey’ is even more intense at the source. You find yourself licking vigorously – not just to please her, but for your own selfish desires to further immerse yourself in the flavor.

“Mmm…” she coos, “My hands can technically do a better job, but there’s something about that external stimulation…” Helen groans.

You disregard the backhanded nature of the compliment and diligently continue your task, increasing both the rate you consume and the speed with which you do so. Her moans intensify, which spurs you further, creating a positive feedback loop. You feel Helen’s vaginal muscles contract (her control over which you’re very well acquainted with.) and push against your tongue. This seems to increase Helen’s pleasure, and conversely yours as well. The act escalates further, and before long you feel a gush of wondrous discharge from her sex.

“Drink deep.” She orders with a final moan.

You comply.
