The clang of metal echoes through the empty weight room. Pulleys and weights rise and fall. Heavy breathing and grunting join the chorus of exertion, and in the center of it all is Amy Rose, transformed, not just from experience, but physically as well.
The hedgehog's inaugural year the majority was supposed to just be about being able to vote and to access adult entertainment for the first time without having to lie about her age online. What she didn't expect was to be zapped by one of the aging Dr. Eggman's contraptions and left fully transformed forever.
It started with strange urges, and quickly developed into the new appendage that bulges against her tight yoga pants. Then, it turned into the desire to use it on others. But, once she ran into Vanilla, the older woman's experience and authority left Amy humiliated and realizing just how weak she was. Sure, it was fun, but more and more, she wanted to be on the other side, being the one in charge, confident, stronger!
Amy lets go of the bench press and lets out a huff of air. She leans over, grabbing her water bottle and guzzling the drink down as she stands up and saunters on over towards the full wall mirror. As the water visibly travels down her throat, her eyes catch onto her arms and her midriff. Gone are the noodles and the undefined tummy, and now there are definitely toned muscles. She pulls the water free from its holster, letting fluid dribble down her neck and over her chest. She smiles and poses, flexing her biceps. "Oh yeah!" she says, feeling the burn and the confidence burning up in her.
Then, comes the rip.
"Fuck!" She shouts, looking down at her pants. The raging hard-on she got from that last set finally broke through the elastic where she had tucked it in. She stands there, looking at the large and throbbing thing, and she drops her water, wrapping her finger around that pole. "This is all your fault, you know," she says, holding onto her dick and giving the large shaft a scowl. "I used to be a cute girl. I used to like dresses and hearts and tea parties with my girls, but now, all I can think about is getting swole and sticking you in things!"
"That sure doesn't sound like someone complainin' about their situation, sugah."
Amy's heart goes into overdrive, all the blood flowing down from her aching muscles and into the throbbing meat between her legs. She glances upwards, seeing the entrance to the gym and seeing the owner of the voice.
"B... Bunnie!?" Amy gasps, hunched over with her hands full of cock.
"You were expectin' someone else, sugah?"
"I... I wasn't expecting anyone!" the hedgehog says, her face turning bright pink, well, more so than usual.
The rabbot saunters on inside and grabs one of the dumbells with her Mobian hand. Sitting on a bench, she curls the massive weight, letting out her slight grunting breaths as she does. She takes a few reps on it, the whole while Amy admires the musculature of her back, her shoulder blades sliding up and down, her sides tensing.
Eventually, Bunnie replaces the weight and walks on over towards the bench press. She grabs some of the weights with her robotic hand and says, "How much you bench?"
"W... wait, me?" Amy asks.
"Sure. You really changed Amy. Why, I remember when you was nothing but a little youngun runnin' around in yer skirts and dresses. Now, yer a real woman."
"Am I, though...?," she asks. "B-besides, I can't bench like this, my pants are ruined!"
"Well, if'n it'll make you feel better," Bunnie says, taking her Mobian hand and pulling up her own top. Her bouncy bunny boobs come out for the hedgehog to see, and Amy can't help but drool at the sight. "Now, don't just stand there, gawkin'. Get to liftin'!"
"Yes, ma'am!" Amy shouts, scurrying over towards the bench. With her gloved hands ready, she grabs onto the bar and lifts, leaving her futanari cock exposed to the air and for Bunnie to admire.
Spotting her, Bunnie begins to talk. "You've been pretty darn quiet these past few months. Everyone's been worried about you."
"Look at me!" Amy says after an inhale. She pulls the weight down and then lifts it up with another significant intake of air.
"Oh, Ah can't help but look at ya!" Bunnie admits. "You're ripped more than a debutante's dress after a midnight rendezvous on lover's lane."
"N... not that!" Amy says.
"Ah, shucks, Amy, you mean the extra equipment? You honestly think ah'd judge you for not bein' normal. Ah mean, have you looked at me?" she holds her hands out, giving Amy a pout.
"Ah... I guess not, but... but things are different. They have to be."
"Sure 'nuff," Bunnie says. "But that don't mean it has to be bad. Take me, for instance. Ah never thought ah'd be a badass cyborg fightin' the good fight, being a hero and all that. That ain't exactly the lifestyle ah was born into. Ah didn't want it. Ah really, really didn't."
"I... I guess that's true.
"But, if none of this hadn't happened to me, ah wouldn't have met my friends and my loved ones. Ah made the best of a bad thing and ah made it work for me. Turned it into a real strength."
Amy finishes her set, and Bunnie lifts it with ease, replacing the weights. The Hedgehog sits up, straddling the bench, her cock practically oozing, screaming for release. "Well, I'm... I'm sorry, Bunnie."
"Ain't nothing to be sorry about, Sugah," Bunnie says.
“I mean, about this.” Amy spins around, wrapping her arms around Bunnie’s body, bringing her onto the bench and burying her face against Bunnie’s breasts.
The rabbit squeals and giggles, her weight pressing down onto Amy’s legs. “Shucks, Amy! What did ah say?” She pulls Amy’s head back and looks into her eyes with a half-lidded, lustful gaze. “There ain’t nothing’ to be sorry about here.”
Amy stares at the sexy rabbot sitting upon her lap. The hedgehog’s futanari cock presses up between the two Mobian women, throbbing with need when pressed up against their toned tummies. Bunnie breaks the awkward silence by running her natural hand over the hedgehog’s quills, and then leaning in, planting a kiss right upon her nose.
“Ah told you there’d be nothin’ to worry about,” Bunnie begins, settling herself in to enjoy the intimacy. “But, there is somethin’ you should be ashamed of.”
The warmth rushes out of Amy’s body and goes entirely to her cheeks. She lets go of the rabbot, her mind racing for whatever faux pas she may have committed. “W… what!?”
Bunnie slides off of Amy, sitting on her knees in front of the bench. The cock flops down, head laying flat and oozing its excitement. Bunnie’s dainty Mobian fingers walk up along the bench, before stopping just short of the cock head. “You went to Vanilla before you came to me, Sugah.” She extends the middle, like a dancer, and then lowers it down, stroking at the throbbing, needful thing.
“I… I didn’t t-think… what about you and…”
“Oh, sugah,” Bunnie says, scooting up to the bench. Her breasts squish against the cold cushion, reaching just short of the phallus. “You don’t have to worry about little ole’ me an’ mah goings-on. All mah relationships are tender, lovin’, and open.”
Amy bites her lip. Her fingers tremble. She wants to grab onto the rabbot’s ears and tug her face right over that pink and excited shaft. But Bunnie pushes herself up, laying on top of the bench, her mouth right there in front of Amy’s cock. “Besides, this is a gift to be shared. So, let’s share and share alike.”
Bunnie opens her mouth, letting out a hot, long breath over the cock. It twitches and lifts up from its position. “Aw… lookie here,” she says, stroking along the underside. “She’s doing sit-ups, the darlin’. Keep it up, and you’ll be big and strong.”
Amy covers her face. “B-Bunnie. Don’t talk to my penis like its a pet.”
“Aw,” Bunnie pouts, holding the head up with three fingers. “But ah want ta pet it. See?”
Amy peers through parted fingers to see the rabbot lean in, wrapping her mouth around the head, plunging it into warm and moist darkness. “B… Bunnie…” she huffs. “I’ve been… working out and…”
Bunnie groans, her tail twitching in delight. She presses her tongue against the underside and swirls around the head, licking up the sweaty surface. Her breasts rub against the bench. She grabs the seat, pulling herself closer up towards Amy. Her moans hum on her tongue and lips, stimulating the shaft.
Amy’s breath gets hotter. Her eyes haze over in her desire. She reaches for Bunnie, but the rabbot’s reflexes are too quick, grabbing the hedgehog’s wrists.
Bunnie stares up at Amy with a furrowed brow, staring hard into the hedgehog’s being. Amy’s arms slacken, and Bunnie’s moves to the hedgehog’s waist, pulling her up, pushing her in closer towards her mouth.
Bunnie pulls her mouth free, spit and precum bridging between cock and lips. She then places a peck on the underside, letting the thing flop down onto her nose. She kisses down lower, rubbing her face downward through the musky thing.
Amy’s lips quiver. Her cock oozes with more anticipation, but she arches her back when lips wrap around her sac, suckling on her balls. “Ah, B-Bunnie!” She whines, falling back onto the bench, panting heavily.
Bunnie’s ears perk up, but she says nothing, instead, slurping over the skin before pulling free with a pop. She rolls her tongue out, chuckling through her open mouth and presses her tongue against one side, painting it with her spit before she runs the tongue down along the other side.
Amy bites her finger, her squeaks of pleasure unbecoming of one as mighty as she thought she was. Her whimpers come out in lower tones, long and whining.
Then, a slight cold comes as Bunnie’s metallic hand wraps around the cock. There’s a smoothness there that her natural hand cannot compete with. The mechanical motions of Bunnie’s smooth metal palm and fingers make the hedgehog squirm in her lack of control.
“Look at you,” Bunnie says. “Ah think a real dominant animal is hiding inside that shell oh yers. Is that why yer here? Ta make yerself big and strong, so you can take a gal like me, bend her over, and ram her until she screams?”
Amy’s pants increase, her voice growing louder and louder
Bunny’s hand buzzes, its vibrations humming and stimulating. The Hedgehog can’t help but scream.
“Don’t you worry about that, Sugah,” Bunnie says.
Amy grips onto the bar, her back arching up, her cream filling the gym. Cum shoots out from her, flying high into the air in long and powerful spurts, before falling back down, drizzling over her abs and over the floor mats.
Amy collapses, still holding onto the bar, catching her breath, even while Bunnie stands up, hands on her hips, smirking down at the hedgehog. “Because ah’m gonna be yer personal trainer. And when ah’m done with you, you’ll be able to take me whenever you see fit. Now, then… are ya ready to become a real fuckin’ beast?”
Amy runs her tongue along her lips, a smile curling up over her cheeks. Her brow furrows, and she growls in response.
“Good. Now, then. Let’s start!”
Amy can hardly believe the situation she’s in right now. She never thought she’d be the kind of woman bench pressing, her muscles strained and toned from weeks of working out. Amy never thought she would rip her workout pants with a throbbing futanari dick that she got from Eggman shooting her with a weird beam. And never in a million years would she ever, EVER think that she’d have Bunnie Rabbot stripped bare. Never would she envision Bunnie’s hands straddling her or Bunnie’s eyes looking down into her face with lustful intent. At the same time, the rabbot rubs her soaking pussy up against the throbbing and needing length.
“Stop zonin’ out on me, sugah,” Bunnie says, a teasing grin upon her face. “You gotta keep yer focus if you’re gonna keep up with yer weights.”
Amy licks her lips and grips the bar tighter. “R… right.”
“Good job, sugah… now… take a deep breath. Remember, Amy, exhale when you lift. Inhale when you lower, alright?”
Amy nods, lifting the bars. Her arms scream with the burning of lifting. All the while, her cock only gets more rigid. It already destroyed her pants from how turned on she was from working out. Now, she has Bunnie basically riding her. The only way this could get worse if-
“Shucks, sugah,” Bunnie says, lifting herself up. From where she once touched Amy’s cock, slick juices slip from her drooling pussy. “This cock can’t just go to waste. Now, you got to deal with the unknown when yer up against real opponents. Gotta work against all the surprises, like this!”
It all happened so quickly. One moment, the shapely older rabbit was hovering over Amy’s cock. The next, she swallowed up the whole thing in her sex.
Amy chokes, seeing the bulge in Bunnie’s stomach, and she loses her grip. The bar falls downward, the strained metal right about to crash into her throat!
Bunnie gasps, her metal hand reaching out, but she stops, her lips quivering, her eyes wide, and her teeth flashing in a big grin. “Amy… you caught yerself!”
Amy’s brow furrows, and her face contorts in red frustration, but soon, she pushes that bar up high with a loud and angry scream! At the same time, her cock swells inside Bunnie. The rabbot leans back, running her metal hand over her ears while her other hand rests on Amy’s stomach. She rolls herself over that length inside of her, letting out a loud, drolling moan. “Ooooh, fuucck, yes, Amy. You really are a strong-un…”
Amy closes her eyes and takes a few quick breaths before she goes for another set. This time, her focus returns to her, and she lifts, exhaling. With each of those exhales, her cock twitches again, and with each spasm, the rabbot rolls over it.
This continues for a bit, the hedgehog’s mind starting to haze a bit more. The whole time, Amy wonders when this will stop. She wonders when she can finally just rest and then give the rabbot what for—what she really needs.
She lost count, pumping iron with grunts and growls that unleashes the beast within her. She wonders if this is what Sonic felt like when he became a werehog--this power, this rage, this lust!”
Cutting her out of her trance is Bunnie, who wraps her robotic hand around the bar. “That’s enough, sugah. We just gotta work the muscles, not punish them. In fact, ah think its time you got yerself a little reward.” She rolls her hips, biting her lips, riding on Amy’s cock.
The hedgehog shakes her head and grips the bar tighter. She pushes against the robotic hand, and Bunnie gasps, feeling the resistance against the robotic digit. She grabs onto the bar herself, gritting her teeth and pushing to return it back to its position. “Sugah, it’s too much!”
“N… not enough!” Amy grunts in exertion. She rocks her hips up, thrusting up against Bunnie. The head of the cock slides up deeper inside the rabbot, and with luck or perhaps some other dark force, it finds just the right spot to send Bunnie reeling back, running her hands all over herself. “Oooh, fuck, sugah, what the fuuuuck!?”
Amy redoubles her efforts, pumping the iron, her eyes focused squarely on the weights and on her arms. Meanwhile, her hips move on their own. She lifts the rabbot with the sheer determination to fuck the woman, sliding up and down, bouncing Bunnie on her hips.
The rabbot throws her head back, her eyes wide and pupils shrunken to pinpricks. Riding Amy is harder than any bucking bronco, and bigger, too! The rabbot has to hold on, gripping hard onto the Hedgehog’s body for any sort of stability. The cock sloshes around inside of her. It rolls the bulge in her stomach around as the hedgehog continues her thrusting upwards. It is only a matter of time, then, before Amy releases, screaming her loudest, proudest roar.
Bunnie’s vision goes hazy as she feels filled up with Amy’s potent futanari seed. It splurts out from within her, coating Amy’s hips and the bench and the floor, and soon, Bunnie is left a twitching mess sitting on top of the still stiff cock of the unflinching futanari.
Amy replaces the bar upon the rack and takes a deep breath. The hedgehog then pushes herself up, sliding to a sitting position until the two are eye level with each other. Though her arms burn, she smirks, looking at Bunnie’s hazy gaze with her fluttering eyes. “Well, now,” Amy says, “that feels fucking incredible. Thank you, Bunnie.”
“Ah… ha… sugah… that was…”
“Oh, I’m sorry… are we done?” Amy asks, her arms trembling, but she moves them up, placing them on Bunnie’s shoulders. “I don’t think so. I’m still fucking hard for you, and I” m ready for round two!”

Bunnie takes a few breaths to try and calm herself. The rabbot’s eyes glance downwards over the sweaty and muscled body of the futanari Amy. The rabbot hardly believes what she’s seeing, and certainly finding it hard to understand what she had just experienced. “Shucks, sugah… whatever happened to you gave you much more energy… Ah wouldn’t be surprised if you could take on Knuckles or Mighty in a fight!”
Amy pushes herself up from the bench, making sure to wipe it down. When she turns away from the rabbot, she makes sure that Bunnie gets a view of her sculpted back.
Bunnie does see it, and what she sees, she likes. “Well, you sure did show me you got the strength, but what about the stamina. If’n yer heart can’t pump the blood to that dick of yers, you’re liable to pass out, ah reckon. You finish resettin’ the bench, ah think ah got an idea.”
Amy does get the bench nice and reset for the next person to come in, probably someone who has no idea that a lot of fucking has taken place. The concept of getting away with boning Bunnie brings a smile to the hedgehog’s face. She begins to turn towards where Bunnie is setting something up, only to stop when she sees herself in the mirror. She’s ripped, there’s no doubt about that, but so are her clothes. What’s left of them dangle in shreds over her body, with only her gloves and her footwear left intact. Sighing, the hedgehog grabs onto the remainder and tears them apart with one fast motion, letting herself bask in examining the statuesque form she has achieved. “Bunnie… I don’t know if anyone can resist me now. I’m… I’m just so strong. I’m so sexy!”
“Sure you are,” Bunnie agrees, “but yer also still training. Now, then, get over here and let’s do some bicycle exercises.”
Amy glances over at Bunnie in the mirror and blanches at what she sees. Somehow, Bunnie has taken apart the exercise bike and attached her robot arm and legs to the stationary wheels. She holds onto the front with her other hand, and her butt points up in the air, her cottontail twitching. “What’s the matter, never gone for a ride before?”
Amy licks her lips and steps up to the contraption. “I don’t see any handlebars here, she says.
“Oh, you don’t?” Bunnie asks, her ears twitching.
With a lewd smile on her face, Amy climbs up onto Bunnie, her cock pressing itself into her filled pussy, squishing out some of her cum from the rabbit’s hole. Bunnie groans, feeling the rough way the hedgehog handles her. At the same time, she slides her dick nice and forcefully up into her womanhood.
“Aah, yeah, Amy…. Just keep it like that, and… and maintain, ugh, a… a steady, but quick, p-pace!”
Amy nods, her shoes sliding into place on the pedals. She pumps her legs, letting out quick, measured breaths. As she pedals, her hips move on their own, a side-effect of the rest of her body exercising.
When Amy puts more weight on her hips, she doesn’t pull as hard on Bunnie’s ears, but when Amy gets a little bit tired, she relies more on her arms to keep herself going. The groans that come from the rabbot change from the pounding pleasure to the masochistic pain of being tugged, and Amy switches to make sure she isn’t hurting her friend. Exercise is, after all, all about safety.
Her legs burn, but she keeps her cock decently buried inside of Bunnie. After all, the trainer has continuously been panting and calling out for “more, augh, more, Sugah!” the entire bike ride. “K… keep it u-aaap!”
Amy does as she’s told and with a toothy grin on her face the whole time. Sure, she’s building up more of a sweat than before. Her heart is pumping so much blood throughout her body. She’s finding it hard to maintain her erection, but a push of the hips from Bunnie spurs her on once more.
“A… ah… Amy, yer… yer keepin’ yourself up so well!” Bunnie says. “H… how’s yer he-head?”
“A… a little, ah… woozy!”
“W… well, t-try to … to pace yerself!”
They keep it up, and Amy does, but her breathing becomes more labored and her actions slower, more deliberate, as her muscles scream, and she works hard to keep herself up. But through it all, she feels the pressure build up inside her, and the reward that Bunnie so deserves shoots out from the hedgehog, filling Bunnie up once again. The two women scream in unison as their orgasms clash against one another. As soon as its over, Amy falls back, landing on the mat, her breasts heaving in her slow, languishing gulps of air.
It’s then that Bunnie pulls herself off of the bike and straddles on top of Amy once again. Bunnie’s ears dangle over Amy’s face, her own body burning with exertion. “Ah… ah… fuck, Amy… Ah… ah ain’t had a workout like that in a long, long time.”
“Y... You’ve done this before?’ Amy gasps in disbelief and in exhaustion.
Bunnie giggles and leans in, giving the hedgehog a kiss. Amy returns one in kind to the rabbit. “Oh, that’s a story for another time, sugah. What we need to do now is hit them showers. Care to join me?”
“C… can’t I just lay here right now?”
Bunnie rolls her eyes and unstraddles the hedgehog. “If’n ya want, but ah’m getting washed up-aah!”
Amy picks herself up, wrapping her arms around the half-turned rabbit. She basically throws Bunnie onto the mat beside her. She snuggles up against her back, the hedgehog’s breasts pressing against the rabbit’s shoulders. “Oh, no, you don’t,” Amy says, whispering into Bunnie’s ear. “You’re going to relax with me and cuddle a bit, Miss Rabbot, and you’re going to like it.”
Bunnie squirms, but not against Amy, but to be the little spoon for her in a much more comfortable way. “Oh, well, Miss Rose, ah do declare, you really are learnin’ to be more assertive.”
And that she is. Amy thinks about all the fun she can possibly have now that she really is strong, now that she really can assert.
And between her legs, her futanari dick twitches in that anticipation.
