This is the story of Katie Tay, who must regain her lost muscles and strength to win the biggest struggle of her life.
Katie’s Muscle Journey
Chapter 1: Katie and Ryoko
As I enter the apartment I share with my boyfriend Jim, I pause for a while at the door. I notice that the door is ajar, and Jim’s shoes are outside. He must be home early from the gym. There’re some muffled sounds that I can hear even from the hallway.
“Jim?” I called out. “I’m back, honey. Are you there?”
There is no reply. I walk into the living room, and I see something I never thought I would see. Jim is sitting on the couch, with his pants down. What I am looking straight at now, though, is the woman standing in front of him.
She has short hair and is topless, wearing only a pair of jeans, and she is muscular. Not like a bodybuilder, or even the ripped physique of a fitness competitor, but extremely strong-looking. Her muscles are shapely and make her very curvy in a feminine way, but her back is ridged with impressive muscle development, as are her abs, which are six solid-looking sections. She is still relatively narrow-waisted. Her deltoids, which are flexed right now because she is holding up her arms in a double-bicep pose, are round lumps of solid flesh. Her bicep peaks can be seen from behind, like small tennis balls. In short, she is almost the perfect woman, even though her thighs cannot be seen.
She turns around and sees me, and gives me an arrogant smile. I take a few steps towards them, not knowing how to react.
She says to Jim, “So this is your girlfriend Katie? Hmm. She doesn’t look as strong as in that picture you have of her.”
The woman gestures towards something Jim is holding in his hand. I ignore his guilty expression, and look more closely. It looks like a photograph. Then I recognize it, when Jim sheepishly holds it up for me to see.
It is a photograph of the two of us, about five years ago, when I was 20. In the picture I’m doing a bicep flex while putting an arm around Jim’s shoulders. I’m wearing a sports bra. At that time I had just won an arm wrestling tournament, defeating a total of six other women. In the picture we both look proud and happy, and my arm looks nice and strong.
But since then I have not been to the gym as much, as I’ve become busier with a new job. I’ve lost quite a bit of weight since that time, and I look leaner now but also flabbier, not as toned as before. For a while Jim kept assuring me that he didn’t mind, and our sex still seemed just as good. But now... I can hardly believe what this looks like.
“Jim,” I ask softly, “can you explain what this woman is doing here?”
But instead of Jim replying, the response comes from the woman, who walks slowly up to me and stands offensively close.
“My name is Ryoko,” she states. “Jim and I have been meeting each other at the gym for a few weeks now. Today, I decided to get to know him a little better, if you know what I mean. However, he seems very loyal to you, for some reason.”
Jim is pulling up his pants hurriedly as Ryoko speaks, and at this he looks up at me and nods eagerly, saying, “I didn’t want any of this, Katie!”
“That’s not what your erection is saying!” Ryoko smirks. She looks back at me and continues, “So, I decided to show him directly, why I am the better woman. I asked him to show me the best picture he had of you, and then I showed him my body and asked him to say who the better woman is. Well, I must admit I was impressed by your photograph. But it seems you aren’t as hot as you used to be.”
Slowly she raises her arms and flexes in front of me, staring at me challengingly. She is still wearing her heels – which is why I didn’t see them outside the door earlier. In them, she is able to look down on me with a few inches’ height advantage. Barefoot she is probably the same height as me, almost. Now it just adds to the overall effect she is having on me.
I take a deep breath to calm myself. Not only am I upset at this woman just coming in to cause trouble and go after my boyfriend as aggressively as this, I am also feeling a bit intimidated. As Ryoko flexes in front of me, her muscles moving seductively underneath her skin, I can see immediately that she is much sexier than I am now, and looks a lot stronger – in fact, even five years ago I may not have been a match for her.
Still, I cannot back down from this challenge. I step back and strip off my tank top quickly, and unhook my bra to stand topless too in my jeans. As Jim gapes in amazement, I step up to Ryoko until our nipples are almost touching, and throw my own arms up in the most powerful flex I can manage!
We hold the posedown for a few seconds, and then Ryoko laughs. I still have some lean muscles on my body, but it is a far cry both from what I used to look like, and what Ryoko looks like now. I lower my arms and hang my head. Without a doubt I have been crushed in this posedown.
Ryoko walks over to the slack-jawed Jim, who is now breathing more quickly at the sight he has just seen. She takes the photograph from his unresisting hand. Turning back to me, she holds it up for me to see, and then slowly tears it straight down the middle, separating the sections containing Jim and myself.
Her message is clear. I glare at her, fists clenched. She smirks and glares back, then points to the coffee table. I give a quick nod to accept her unspoken challenge.
No words are needed. We both step slowly to the coffee table, still holding each other’s gaze. I go down on one knee, on one side of the table, and she copies my pose. The coffee table is small and circular, so we end up using our right knees to brace it between us. Still with slow deliberate movements we raise our right arms and plant them on the table, and hook our thumbs, preparing to arm wrestle.
Still not saying a word, Ryoko raises her left hand and crooks a finger at Jim, to come over. He does, looking at the both of us in awe, obviously trying to drink in as much of this sight as possible. Then Ryoko speaks again.
“Jim will be the referee for this contest between us. The winner will give him a blowjob. During the match, he can choose to motivate us by letting whichever of us pleasure him with our hand, mouth, or any other part of the body. Now, get ready to be shamed in front of him!”
“The relationship we share will give me the strength to beat you in front of him and make sure you never come after him again!” I reply firmly, clenching her hand as hard as I can. I will not lose to a bitch like her!
Jim holds our hands and makes sure our starting position is equal, and then releases his hands to let us begin. We both lean forward and start pulling. My bicep bulges nice and round, and I feel encouraged even though it is obvious her muscles are bigger. So far I am keeping her even.
Then I look up into her eyes, and my heart sinks as I realize she is feeling much more relaxed than me, barely straining compared to me. She may be just toying with me. I press my lips together grimly, not letting her see my anxiety, and concentrate on just pulling as hard as I can, increasing my force until I am nearly using my full power. But she is matching me strength for strength. Our hands begin to tremble in the middle between us with the sheer force of our battle. I can see her starting to strain a little bit, but she still has that small mocking smile that I would dearly love to wipe off.
Meanwhile Jim has taken off his pants completely, and is starting to masturbate. He moves closer to us, and seems to hesitate for a moment.
“Choose me, choose me...” I urge him in my thoughts.
Yes! He’s moving towards me. Now he’s rubbing his cock against my shoulder and upper arm. I am even more heartened when I see the frustration enter Ryoko’s eyes. It feels so good against my sweaty skin... My arm begins to feel stronger, and with a loud grunt, I manage to gain on her a little bit, the first progress either of us has made in this match!
But she manages to counter my effort, and hold me only at a slight advantage. Looking up at Jim, she smiles in a sultry way and says, “Are you sure you won’t rather have this instead, Jim?” pointing to her larger and more defined arm muscles, now put on full display because of the angle. “You know you want it... come on, put it right here... come and find out how a really strong arm feels like...”
I can’t believe it, Jim is actually falling for that! He’s moved his cock away and is now pointing it at Ryoko... I can’t stand it, she’s smirking at me! I pour more strength into my arm and pull as hard as I can, but I make only a little bit more headway. This actually makes her showcase her bicep even more, and she angles her body to the side so that Jim has space to move in... and put his penis against the round, solid lump of muscle, beaded with sweat... it even has a vein showing slightly near the elbow...
I pull with all my might, but somehow I can’t give it my all. My spirit is being sapped by the sight before me, my boyfriend’s cock just inches away from me, so near yet so far. It’s as if he is giving strength to Ryoko instead of me, and widening the disparity between Ryoko and me. Because it’s true, I can feel it: Ryoko is definitely stronger than I am.
Ryoko’s face is rubbing against Jim’s stomach, and she moans and rubs her cheek against him, seeming to enjoy herself very much, as if she were not arm wrestling with me at all. She says, “Jim, move back. I’m going to beat your girlfriend now, and I need space.”
He complies. I brace myself for the effort that I can feel is gathering behind Ryoko’s hand. She takes a deep breath, and looks me straight in the eye as she begins to ramp up her effort. I look back, trying to keep my expression neutral, but my trembling arm gives away the fact that slowly she is overpowering me. The crushing force of her grip is starting to actually hurt my hand, and easily she pulls me back to the centre, losing me all the ground I gained. We stare at each other as the match continues, beads of sweat pooling visibly on our faces. I can feel the sweat drops on top of my upper lip, and also starting to run in rivulets down my chest.
Slowly, with excruciating slowness as if she is purposely prolonging it, Ryoko pulls my arm down steadily until I am more than halfway down. It’s only in movies that people can make a huge comeback from this situation. Maybe sometimes in real life but the person has to be extremely strong. As I am now, I simply cannot manage it against her.
Yet, with Jim watching, I cannot afford to give up. I refuse to give up, and I keep straining with all my might, trying to pull back up again. Jim approaches, holding his cock. I turn to him and open my mouth hungrily, but it is to Ryoko that he turns. Ryoko obligingly opens her mouth, and right in front of my eyes, Jim inserts his throbbing dick into her face, moving it in and out.
I give a sob, heartbroken. I cannot believe I am being so humiliated right now. Crying out, I give a jerk on Ryoko’s arm and try to use my body weight for leverage, but Ryoko simply holds me out and rides out my surge for the few seconds it lasts. Now my hand is mere inches away from the tabletop.
I call out, “Jim, please, give it to me... put it here, on my bicep... I will squeeze it hard as I pull up... please Jim, honey... I can do it... I can do it...”
Jim hesitates, and as I look up I see the conflicted look on his face. Then he pulls his cock out from Ryoko’s mouth, and she looks disappointed. I feel some hope again as he bends down and fits his cock snugly in the crook of my arm. I take a deep breath and flex my bicep as hard as I can, letting the full strain show on my face, not bothering to hide it. Ryoko snarls and says, “I will not let you do that, little Katie. Jim, she’s just going to disappoint you. I’ll show you!”
The seconds tick pass as Jim waits patiently, giving me a chance to prove myself. I am flexing with all my might, my vision blurs as my eyes are screwed almost shut, my muscles are burning with effort as I flex as hard as I’ve ever flexed. I keep my eyes fixed on Jim’s penis, nestled between my forearm and my bicep, and I want so much to curl my arm up around it, and let him feel the strength of my bicep directly on his cock...
I’m not sure but I think almost half a minute has passed. Ryoko has kept my arm down, and not let me move up even a little bit. Both our arms are trembling with effort, but my arm is burning with fatigue. This match has already lasted a few intense minutes. I’m so out of practice, and out of shape, I’m clearly not used to this level of exertion anymore. My arm fails to flex enough to squeeze Jim’s cock even a little. In fact she even pulls my arm down slightly, just a little bit.
Jim sighs and straightens up again, and my heart aches again. Why must I lose this way?
He goes over and runs his hands all over Ryoko’s muscular rippling body, now lubricated with sweat. Ryoko moans, especially when his hands run over her nipples. He begins to fondle her nipples. She shudders with pleasure all over, and I feel her strength flag slightly, but by now I am too tired to take any advantage of it. I am already barely holding on, with the last bits of my strength. My arm is really starting to hurt.
But Ryoko refuses to let me go. She pulls me down to within just an inch of defeat, and there she holds me, content to let me strain and strain, knowing that I will not give up until I really can give no more. She’s right. It’s hopeless, but I simply will not give up, despite the tears of pain running down my cheeks, despite the terrible growing pain in my arm and shoulder. I think I am crying because of the shame as well, it’s hard to tell.
When she is sure I am completely spent, and holding on only by sheer willpower, she grabs Jim’s cock with her left hand, and says, “Now, you are finished.”
With that she slams my hand down on the table, and pulls Jim’s cock towards her. A few quick thrusts inside her mouth is all it needs, Jim must have been holding it in for all this time. She’s not letting go of my hand. I am forced to watch helplessly while across the table this woman gives my boyfriend a victory blowjob.
As Jim staggers back, gasping and groaning, Ryoko turns back to me and parts her lips slightly, letting some of the cum drip out of the corners of her mouth. She plants her left palm behind my head and shoves my face forward to meet hers, and she forces me into a kiss. Her mouth forces my lips open, she invades my mouth with her tongue, and I can taste the salty familiar tang of Jim’s cum, but now mixed with the taste of Ryoko’s saliva. She forces me to taste this horrible combination for several long moments, before letting me go. I am gasping for air, breathless from the exertion and also from the kiss. She’s breathing hard too, but there is the flush of pleasure in her eyes. I slump, rubbing my sore right arm, tears of shame in my eyes. She has outmuscled me in front of Jim, and shamed me with her cum-covered kiss.
As she poses proudly for Jim, her muscular arms raised in victory, I open my mouth to speak.
“I’ll wrestle you.”
Ryoko’s eyes gleam, and she answers at once, “Yes, let’s. I look forward to crushing you totally. You will feel my mastery over you with your whole body. Then, after I beat you, I will make you cum, so that you know you’re just my slut, and you love losing to me. To top it off, your Jim will fuck me from behind while I’m on top of you, so that you know you have lost completely, as a woman.”
Jim looks guilty, but doesn’t say anything. I can tell that he likes what is happening, even if he feels guilty about what is happening to me. But this is not about him. I do not feel that much pain from the fact that he has effectively betrayed me. He cannot help being sexually turned on by all this. He’s just a weak male, unable to resist a woman like Ryoko who is everything he’s always wanted. I guess I used to be that woman too.
That’s why I am going to accept now. This is about Ryoko and me. Woman to woman. Muscle against muscle, will against will. If I cannot defeat Ryoko, then I do not deserve Jim in the first place.
We stand up, and we strip off our jeans, Ryoko kicks off her heels as well. She’s wearing a pair of thongs, which she unhesitatingly strips off too. I match her by stripping off my panties, so we’re both completely naked. Now I have the chance to see her legs. They’re sleek and well-muscles, like dancer’s legs. My legs are less muscular now, and look a bit fatter and less defined. I still have a nice calf bulge, but so does she. We move forward to compare legs, and we parade them in front of Jim.
“Come on, Jim darling, tell us, who has the better sexier legs?” Ryoko says.
“Um...” Jim looks clearly uncomfortable, but in the end avoids my pleading look and mumbles, “You, Ryoko.”
“That’s right, and you’ll get your reward after I beat this weak girl and become your new girlfriend. You’re looking forward to that, aren’t you?” Ryoko says, reaching over to tilt his face with her hand. I reach up and slap her hand away angrily. We both glare at each other, and bump chests.
“Titfight,” she says, and that is all the signal we need – we put our hands behind our backs, to throw our breasts out, and begin bumping and crashing them together, sometimes swiping from side to side. I used to be proud of my perfectly shaped breasts, but they’ve grown smaller over the years and less firm. Ryoko’s are larger and firmer. Within a several exchanges I am gasping with pain from the friction on my sensitive nipples, and on the impact from each breast bump she is dealing me. We bump harder and harder, and she is grunting with the effort, but she doesn’t seem as hurt as me. Some minutes have passed, I don’t know how long, but I finally have to step back, avoiding her breast attack, my chest heaving as I gulp for air and my hands coming up to cover my sore nipples and breasts. I’ve lost this one too... it’s so embarrassing...
“You’re not woman enough for me!” Ryoko screams, thrusting her arms up again in victory. Jim moans and begins rubbing himself. The sight of our struggle is apparently the sexiest thing he’s seen in a long time, because despite his refractory period he’s getting hard again.
My heart fills with rage towards this woman. Giving vent to a scream of anger, I step forward, raising my arms too. Our hands make contact, and we eager clasp fingers, gripping each other’s hands hard. Our arms and bodies begin to tremble as we engage in a test of strength.
We press our foreheads together as we push, channelling all our strength into this contest. Her full power is incredible... My arms are really feeling the strain, especially my tired right arm. Oh no... it buckles. My right arm was just too tired. She’s not showing me any mercy, she’s surging forward full force... my body is now bent awkwardly, my right arm unable to match the strength of her left and unable to straighten. She’s pushing it out and to the side, so I can’t use it fully now.
My left arm is not so good at muscular power, but more for endurance. Now it’s being tested to the limit. Her right arm is a bit tired too, I wonder if I can turn the tables on her. I have to... Jim is watching us wrestle... I must show my strength to him.
We are frozen in position for what seems like long minutes, with me putting all of my remaining energy and strength into this contest, resisting Ryoko with all my might. Every muscle on our body must be sharply defined to the watching Jim, but I cannot spare much attention to look, I can only catch glimpses of the muscles standing out on the body parts I can see. Ryoko’s right arm is like a pillar of strength. My left arm is starting to shake. I will myself to ignore the pain in both my arms, and concentrate on pushing.
It is no use. I can feel myself weakening, my strength draining away. Ryoko is overpowering me slowly but surely. My left arm has just given way, and it’s slowly and shakily being forced downwards too. Now Ryoko is leaning forward and pressing her chest against mine, bending me backwards. I bend back as far as I can, but I’m not very flexible. Soon I cannot help my knees buckling, and I start to sink down before her.
I’m now down to one knee, her hands are holding mine down, it’s hopeless, she’s too strong for me. She kicks at my upright leg until I am forced to go down on that knee as well. Now she’s clearly in a position of dominance over me. She leans over, and pushes hard. My wrists are being bent, they hurt! It’s so painful...!
She is telling me to submit. Never! I must not... not in front of Jim like this, and not to her!
“No!” I say through gritted teeth.
“You have no choice!” she grates out, and jerks downwards, letting me feel her crushing force. I scream once in pain, and my hands are pressed all the way down to my shoulder level. She’s now bent over almost double, her face near mine.
“Submit!”
“N... No!” I gasp out, tears starting to flow out of my eyes.
She invades my mouth with a kiss again. I try to bite her, but she growls and bites back, causing me more pain than I can cause her, so that I try to break off the agonizing kiss, shaking my head side to side. But I cannot shake her, and she completely violates my mouth before raising her head and suddenly twisting to the side, catching me in a headlock.
Quickly her weight forces me down onto the floor, and I can’t break out of this headlock. She’s squeezing so hard with her left arm, I can feel all the hard muscles all along it. I feel as if I’m blacking out, she’s cutting off my air supply...
I must have blacked out for an instant, because now she’s released the headlock and has me pinned to the floor. She’s locked her hands with mine again, and is pressing them on the floor. I thrash around with my legs, but very quickly she locks her legs around mine in a grapevine. She is not only strong, but also an expert wrestler it seems. I’m completely outmatched.
She has me pinned helplessly. As her legs stretch mine, I grit my teeth, determined not to cry out in pain. The effort makes sweat break out all over my face. My suffering is plain for her and Jim to see as my mouth opens in a soundless scream, and I shake all over underneath her, but still I am not screaming or crying out. The pain is building and building...
“Count, Jim!” I hear her say. Opening my eyes, I look straight into her face, as Jim begins to count to ten. The pain cripples my efforts to try and power my shoulders off the floor, but even if she had not slapped on the grapevine, I think I would still be too weak compared to her to do it. I think she knows it too, she is grinning down at me as Jim finishes a slow count to ten. I have not been able to lift my hands or shoulders even a little bit off the floor.
“I have beaten you at wrestling,” she states. I cannot deny it. “Now I will make your defeat final. I will make you cum.”
She releases the grapevine and shifts herself so that our mounds are touching, and she angles her pelvis so that our clits make contact. Her legs twine around mine silkily as she starts to hump me, clitoris against clitoris, sex against sex. I close my eyes and try to resist, willing myself not to cum, but the stimulation and the struggle have made me very wet. My body is betraying me. Ryoko is wet too, she must be feeling so turned on at dominating me so completely, and yet I am unable to make her cum first. I look away and close my eyes as my body shudders its surrender under her, the spasms of unwanted pleasure making my body jerk back and forth like a marionette under her control.
She rises up onto her knees, still on top of me, and slowly flexes her arms, clearly savouring the moment. I am helpless underneath her. My spirit has been broken.
Ryoko lowers herself over me again, on all fours. Looking into my eyes, she says, “Submit.”
I bite my lip, and close my eyes. I feel a stinging pain. She’s slapped me. “Submit.”
“I submit.” I have lost. I feel it now. I have admitted defeat inside myself.
“Who’s the better woman?”
“You are.”
“Louder.”
“You are the better woman.”
“Tell Jim who is the stronger, sexier and superior woman here.”
“Ryoko is the stronger, sexier and superior woman.” I am really crying now, but my voice comes out as steadily as I can make it.
Ryoko groans as Jim takes her doggy-style, grabbing her breasts and fiddling with her nipples as he urgently penetrates her with his shaft. Throughout the whole session, she and I never break our stare, except when I blink the tears away and when she blinks sweat out of her eyes. When Jim finally reaches a long shuddering orgasm inside Ryoko and collapses to the side, it’s as if he doesn’t exist to us, that the fact of sex with him serves only to cement Ryoko’s victory over me.
Ryoko whispers to me now, still not looking away, “You will want a rematch.”
“Yes... I want a rematch.”
“You can have one only when you are strong enough to challenge me. Because the next time you lose to me again, you will lose forever. I will keep Jim. More importantly, you and I will both know, once and for all, that I will always be the better woman. Do you understand?”
“Yes, I understand.”
“I will let you challenge me again. But you will not win. I will train too, in the meantime, and stay ahead of you.”
“I’ll train harder than you, and become stronger than you.”
“You can dream on. In the meantime, your Jim is mine.”
With that, she slides off me, and carries Jim in her arms easily, struggling only a little bit. Looking down at me one last time, she walks off with my boyfriend into the bedroom, to fuck his brains out even more, while I am left to slowly recover from my utter humiliation and complete defeat.
