1.)
You’re at the local state park with your girlfriend, Helen. The two of you are in your 20s and are fairly average. You stand at 5’10” and weigh 165 pounds, while Helen is 5’4”, 150 pounds.
It’s a beautiful day outside at around 10 AM. To your surprise, the park is almost empty. In fact, you haven’t seen anyone else walking around. It’s a weekday, but you thought there would be retired people walking their dogs or shift workers like yourselves that have the day off.
You’re out with Helen today because of her new “initiative to lose weight” that you’ve been roped you into. You don’t really need to lose mass, but you’re not in great shape either. Helen is the definition of “thick”, but a bit too much. You’re glad to see that she’s trying to turn things around, and you’re willing to help her by accompanying her on a hike today; plus, it’s fun to spend some time with her in a new setting.
Helen’s hair is brilliant bright blond, and shimmers in sun’s golden rays. She’s wearing a tank-top and shorts, her ample figure spills out from both. Her hourglass figure packs away most of her fat into tight curves.
The two of you make your way onto the central hiking trail. This state park has multiple interconnecting paths based around an extremely large hill. Large enough that you’ve mistakenly referred to it as a mountain before.
Helen walks in front of you, her large round bottom sways back and forth. You imagine what it will look like after she loses some weight. You wonder if it would be possible to convince her to start weight training in addition to her other exercises. You think, ‘With ample squatting, the booty could ascend into something wondrous.’
Suddenly, Helen says, “I’ve got such a great feeling about today!” She’s especially cheerful.
“Oh yeah? Why’s that?” you respond.
“Hard to explain, just a feeling I have. I think something big is going to happen.”
“Riiiight. Well, maybe today is the day we have a little forest-action?” You ask, getting your hopes up.
“Hey! I can’t believe your mind has already gone to that!” she replies, shooting you a funny look.
“What? How can I help myself when I have this great view of your backside?”
“Oooh, you’re really cheeky!” She slows down and matches your pace, “Ha! That’ll serve you!”
“You think that’s going to stop me?” you reply with a smirk on your face.
“I don’t see how it doesn’t…”
Without saying another word, you reach over and grab onto her yoga-pants covered bottom, squeezing the firm and ample cheek; your hand fails to encompass the sizable bubble.
“Hey buster, this is a public park,” Helen says under her breath.
You shrug, “It’s supposed to be, yeah, but I haven’t seen a single other person around. In fact, our car was the only one in the parking lot today…”
“Well… I guess you have a point,” she concedes. “I’m just surprised you like my butt so much.”
“Why wouldn’t I? It’s one of your best features,” you smirk.
“I won’t disagree with that, but I’m telling you babe, once operation weight loss goes into full swing, it’s going to be way better than it is now.”
“Hmm… we’ll see,” you reply, still holding onto the cheek in question, “Say, I normally wouldn’t bring up this kind of thing, but since you’re going on about changing your butt, have you considered doing squats?”
Fortunately, Helen doesn’t seem to take the question the wrong way, “Actually, yeah, I have. I’ve been reading about how I really should be weight training if I want to change my body. I guess I’m just kind of afraid that you’ll hate it if I pack on muscle. My body stores fat so easily, which I’ve read is an indicator that I might gain muscle quickly too.”
You think about how to approach this. The truth is, you love muscular women, but you’ve kept this secret. You’ve dreamt many times of Helen’s fat replaced with proud, rippling muscle.
After a moment of consideration, you finally respond: “Well, obviously I don’t want to push you into anything you’re uncomfortable with, but if you were to build up your muscles, you can rest assured that I’d support you all the way.”
Helen seems somewhat surprised, “Really? You would? I mean… if I were to try, it’s possible that I’d get really buff…”
You recall a cheeky quote to use, “Hey, you know what they say: Arnold Schwarzenegger didn’t accidentally become as big as he is. If you start lifting and you feel like you’re gaining too much muscle, you can just stop.”
“True,” Helen concedes.
A few moments later, she starts laughing.
“What’s up?” you ask.
“I just,” Helen chuckles again. “Oh man, I can’t stop imagining myself with Ahnald muscles,” she explains, intentionally mispronouncing the actor’s name for comedic effect. She mockingly flexes her arms, which to no surprise, accomplishes little.
“Heh, yeah…” The truth is, you have imagined this – well, something like it at least. “That would be pretty crazy… huh?” There’s something off with the tone of your voice, and Helen can tell.
A few moments of silence pass before Helen adds, “Well, what would you think if I had Schwarze-muscles?”
“I’m not really sure how I can respond to that since it’s impossible.” You try dodge the question for the time being.
“Oh, come on, that’s no fun. Just imagine it. Like, if I had big, bulging muscles on my body. I’d be the same height, but, with like… I dunno, biceps as big as my head!”
Deep down you want to scream that you’d love it and would go so far as to worship those mighty arms, but you don’t want to freak Helen out. Instead you defer for now.
You respond: “If that were the case, your arms would be a lot larger than Arnold’s. Most human heads are around 28 inches in circumference when measured around vertically. Although, they’re really like 22 inches when you measure horizontally for a hat or whatever, but that doesn’t match up to the visual of a flexed bicep. I guess, when following the second measurement, Arnold biceps would match up, but, yeah, I think you get the point.”
“Err… Why do you know that? Like in such vivid detail?”
You blink a couple of times. The truth is, you know this because you once read a female muscle growth story in which one of the girls flexed up a bicep “as large as her boyfriend’s head” and you wanted to know exactly how big that was, which led you on a binge of late night internet searches.
“Oh, I took an anatomy course in college,” you lie.
“Huh. Interesting you remembered such a weird fact. Well, okay then, what if I had arms even bigger than Arnold’s?”
Uh oh. Not quite ready to play out your hand, you continue the game for a bit longer, “Well, I guess it depends on if you still have your boobs and hips.”
Helen takes a few moments to process what you’ve said before she responds, “You know, that’s a good point.”
“It is?” You mull it over for a moment before convincing yourself it is a good point…
“Yeah, it is,” Helen affirms. “Like, I guess if you think about it, most of those bodybuilder chicks end up looking kind of gross to most guys since they lose their breasts. The ones that really take it to the extreme have altered faces, deeper voices, that sorta stuff. So… Huh. Well, I guess for the sake of this little thought-experiment of ours, let’s presume that I’m somehow able to keep my boobs, and that my hips remain proportionately wide. My voice also stays feminine, as does my face and everything else.”
“So, just to clarify, you’d be something like one of those muscular female comic book characters?”
“Huh… I guess? I can’t really think of any. But, sure, I guess I’d be unrealistic. It’s a fantasy after all.”
Time to finally admit some truth, “Well, sure. Under all those stipulations, yeah, some Arnold muscles would be cool on you.” You pause before quickly adding: “Of course, I’d always love you regardless of you look like. What really matters is what you want.”
“Hmmm…” Helen starts to giggle
“What’s so funny?”
“I just can’t stop thinking about me with big, powerful muscles. I mean, let’s get real, assuming I did get to keep my curves, I’d definitely look a lot better with them than all this flab.”
You remain silent.
Fortunately, Helen continues: “And, you know, since I’d have some body fat, I’d get all the benefits of muscles. So, I’d be full of energy and super strong. In fact, if my understanding is right, I’d potentially be a lot stronger than most bodybuilders since that uber-ripped look lowers their performance. This little fantasy is sounding better by the moment. I bet I’d be able to pick you up and carry you around all the time!” She giggles again.
“Would you… be bothered by that? Being stronger than your boyfriend?”
Helen shrugs. “I’m a modern girl. I’m cool with being the powerful one. I think the real question is if you’d be bothered by having a stronger girlfriend.”
“Yeah, sure I’d enjoy it. As long as our relationship doesn’t suffer or anything like that.”
Helen considers the past exchange for a few moments, then replies: “Well… What would you think about me having some realistic muscles? You know, like, maybe I lift heavy, go hard, and see what happens?”
“I’d support you all the way,” you reply with a warm smile.
“But would you like it? Real talk, this isn’t a trap or whatever. Do you think I’d look better with muscle on my body instead of fat? Don’t lie.”
You’re somewhat reluctant to respond despite her assurances, but ultimately give in, “Yeah. You would. Again, I have to reiterate that I love you just the – “
“That settles it!” You’re interrupted, “This afternoon after our hike I’m going to hit the weights. It’ll be all your fault when I turn into a muscle-beast!” Helen giggles playfully.
Your heart accelerates as you spend the next few minutes in silence wondering what lies ahead for your future.
2.)
It’s been about 30 minutes since your discussion with Helen about muscles. Despite her initial bravado, she’s trailing behind you. Your mind has been wandering for a while, and you failed to notice just how far back she’s fallen.
“Hey, can we hold up for a bit?” Helen calls from behind.
You turn around, and head over towards her. The two of you meet halfway.
You look over at Helen, panting and heaving as she catches her breath. Sweat drips down from her forehead and accumulates at her joints.
The truth is, you don’t really find her to be attractive in this state. You feel guilty for it, but you start imagining Helen with a ripped, muscular body. And it’s a much more pleasant sight than reality.
The awkward silence breaks as Helen says, “Hey, look at that.” She points to the sun, covering her eyes as she looks towards it.
“Whoa… The sun is… pink! Looks like a sunset, but isn’t it only like 10:30ish now?” You pull out your phone to double-check the time. After tapping the screen, you see that it’s a little before 11, but for some reason you have no connection at all. “Hey, Helen… Is your phone working? I have no service apparently.”
Helen reaches into her pocket and retrieves her phone. A moment later she reports, “Same here. That’s weird, I’ve been on this trail before and never had a problem…”
You wonder if the sudden loss of cellular connection is correlated with the strange pink sky.
“I’ve never noticed how great the sun feels,” Helen says. She stretches her exposed arms upward and outward towards the sky. Her skin is especially pink under the unusual sunlight.
“What do you mean?” You reach up with your own arms but feel no different. “Same old sun to me. Plus, I thought you were actually a bit more outdoorsy than I was.”
“True. It’s just different this time. Hard to explain.” She twists around, exposing the rest of her body to the sun. Whatever she feels, it’s making her deeply satisfied.
“Right… Well, whatever floats your boat.”
“Mmmm… Gosh, I could just sit here forever! I want more sun!” Helen takes her tank-top off, revealing her flabby midsection. She sighs with relief and stretches herself out touch more sunrays.
“Well, the hill, mountain, whatever you want to call this, it’s tall enough that the higher we go, the closer to the sun we should be. Though I don’t think it’ll matter much,” you explain.
“Good enough for me! Plus, I’m suddenly feeling really recharged. Let’s get going! Guess I should put this back on…” she says before putting her tank-top back on.
Your mind drifts to fantasies of what Helen would look like with a rippling six-pack.
She bounds off in front of you, brimming with newfound energy.
Perplexed, you follow.
3.)
You walk with Helen for a while, mostly occupied with idle chit-chat. To your surprise, Helen’s keeping pace with you, and doesn’t seem tired at all anymore.
Randomly, Helen looks down at her arm and pokes it. “Hey, check this out!” she says before flexing it – surprisingly, a round, bulbous bicep pops up. She reaches over with her left hand and grabs onto her right bicep, kneading it. After playing with her arm for a few moments she lets go. “You should feel this!” she offers.
You reach over and squeeze her arm. To your surprise, underneath the initial layer of fluff it’s hard – really hard, and you can barely budge it. Helen grins, and you twitch with arousal at the possibility that your girlfriend has spontaneously developed muscle.
“You like it.” Her eyes sparkle.
You let go and think about what to respond with. You decide, “Of course I do. It’s your arm, and I love you.”
Helen’s eyes narrow, she’s onto your game. “I meant the muscle, dummy.”
“Right. You’ve always had muscles on your body. That’s why you’re nice and thick.”
A half-smile forms on Helen’s face. “Sure, I’ve always been thick, but I’ve never had guns like these.”
“Hmm… I dunno about that…”
“Oh yes you do. You think I haven’t noticed that you always grab onto my arms during sex?” The half-smile has transformed into a full-on smirk.
“Well…”
“So, either you’re an extremely inattentive boyfriend, or you have to admit that these muscles are new.”
You swallow. “Alright. Fine. Your arms do seem more solid than usual.”
“And you LIKE it!”
You shrug. “Of course. Didn’t I just say that I’d be all over you with Arnold arms?”
“Actually, you said you’d be all over me if I had arms bigger than Arnold.”
“Whatever. Same difference.”
–
A few moments pass, and Helen extends her arms outward, flexing her triceps. A large discernable bump bulge out. Wordlessly, you reach over and squeeze it. While it isn’t the rippling horseshoe of power that you’ve fantasize about, it’s certainly hard. Hard enough that it’s arousing to touch.
‘There’s no way Helen had this muscle before,’ you think. ‘Then again, I can’t really recall a time that she’s flexed like this before, so maybe she’s always had this muscle underneath.’
