Sisterly Love
Sitting now alone in his usually occupied dorm room was a lean boy, roughly around the age of 20. He’d gotten a ride out of the gutter town his parents stayed in on a sports scholarship, though it was difficult to get anything done because the school in his hometown was absolutely terrible compared to Macherson University. The staff here actually cared about learning and could be talked to, while back at home he could hardly hold a conversation without being completely ignored. A little flit of his pen over the mostly unanswered math questions, a good five pages of it left to go – and seven to go with his biology class. Thankfully, most of the professors understood he wasn’t exactly as privileged to have high-end Highschool classes, so they usually offered to give him remedial class work in between semesters to catch up and keep himself there. A soft sigh, raising one of his hands to run across his muzzle and head. There was a slight sound of keys near the entrance to the dorm room, causing the dog’s ears to perk upwards and turn his head.
In walked Jaime, a cat girl almost like Alex himself, at least in coloration. The girl gave a smile, slipping her long wool coat off and showing off the warm-looking sweater and skinny jeans underneath. Always with the reds and browns, Alex thought to himself, probably to contrast with her pale fur.
“Hey Al. I didn’t see you at the study hall today, something up?” The curious tone to the girl’s voice was betrayed by the knowing and all-too knowing grin.
A little squirm in his seat, the dog tried to think of something other than the usual excuse he gave, “Look, I love to hang out with you, but everyone else here assumes I’m not some, like, trailer park trash…”
Jaime rolled their eyes, walking over to the boy’s side of the room and sitting down on the bed just next to his desk, “You know you’re not trailer park trash. Are you at least keeping up on your studies and stuff?”
Without really missing too much of a beat, Alex huffed, “I mean, I’m trying to? It’s hard sometimes. I mean, it’s easier with you here, but…”
The words hung in the air for a few awkward moments before Jaime laughed it off, leaning in to give the lean dog a soft, warm hug. For a moment, Alex almost wanted to ask her to stay there for a little while longer, but managed to bite his tongue back as the cat girl sat back down, “Alex…you know I love you like a brother, and I’m happy to help. There’s no need to be shy, okay? Big sis Jaime is here to help if you need it.”
For some reason, the words left a light pink tinge on the boy’s face, but he did his best to ignore the sensation of fluttering in his stomach and focus on the equations, “I know, Jaime. I appreciate it. You’re the only person I really trust here besides the professors.”
There was a shifting nearby as Jaime got up from her seat and patted him on the shoulder before heading to the shared quaint kitchen, already opening the fridge and a cupboard to cook something up for the both of them, “I’m going to make some steak and potatoes tonight. Nothing fancy though, so don’t worry – I’m sure you’ll like it,” A pause to lean back and grin at him, “And don’t burn your brain out on those problems!”
Maybe a friendly sticking out of his tongue, but Alex wouldn’t really respond much. There was an exam not a couple weeks from now, and he wanted to make sure he had these equations stuck in his head before they got too close.

By the time that dinner was done Alex had run himself dry trying to get the work done as quickly as possible. Jaime poked her head in to try and provide some help while the food was being cooked all on its own, but it didn’t help while she was leaning over him with her chest covering his ears. Sure, she wasn’t huge, but she was clearly taller and perhaps just a slight bit more toned than he was.
Both of them were eagerly digging into the food, though Jaime a little less so. Being raised as such a prissy, fancy girl meant she normally ate pretty slowly and preferred more the conversation than the food. Alex just wanted to get as much food in himself as he could, growing up in the kind of household that meant if you didn’t eat it, someone else would.
“So. Have you made any progress with finding out which degree you want to work towards, Al?”
There was a definitive silence, an uncomfortable one; Alex hadn’t figured out what he wanted to do with himself just yet. The sport scholarship got him to classes here with some extra help from his Aunt, but at this point he was going to be riding on loans, “No…not really. I mean. It’s hard Jaime. You’ve so perfectly figured everything out, and I just…it’s hard to think about what I want to do when I’ve never had that kind of opportunity before now.”
Jaime would grimace and, after taking a bite of her steak, would respond, “Al, you know I’m willing to help if you need it. I care about you, y’know. I know life’s been hard on you, and I wouldn’t mind trying to make it a bit easier for you.” A loving tone to her voice, one he was familiar with.
He heard her of course, but his head felt like it was swimming. For a few moments everything was a little unfocused and felt surreal. Like he was looking through a pair of glasses, rather than his own two eyes.
The cat girl’s hand gently knocked on the table a few times to snap him out of his slight daze, “You’re my little brother in all but blood…and law, technically. But hey, what’s that mean now adays?”
They both shared a little, slightly nervous laugh, and continued to eat their food. This left him thinking though, what did I do to get such an amazing friend?
A quiet yawn in between bites of the almost finished mashed potatoes, rubbing his eyes a little. He must’ve really tuckered himself out that day with the training in the Gym and classwork. Jaime brushed her hair back and smiled warmly, “Ha, already tired? Well hey, we can hang out if you want, still.”
He lightly tapped the top of his fork in thought, though really, he wasn’t going to say no. They weren’t always able to really sit down and talk, let alone relax together because of their mixed schedules. Moreover, he couldn’t deny he had a thing for the cat girl. If anything, he was making a little show of wondering what to do so that it didn’t seem too weird for him to be eager.
“I mean, it would be nice. I’ve been running around a lot and trying to punch through those dumb quiz questions. What uh, what do you have in mind?” His breath hitched slightly near the end, not able to keep his damn shyness in check.
Whether she noticed it or not, her face didn’t stray from the soft smile and warm expression, though the cat did give a little giggle, “Oh, well. We could watch that movie you liked so much. It was the one with wizards or whatever right?”
A little scoff from the trailer-born dog, folding his arms indignantly, ‘It’s only the greatest movie series ever made. It’s called Forbidden Realms, I used to watch the TV show when I was a kid.”
He could remember the show fondly, always about a wizard or warlock named Drimae who travelled across a bunch of weird, strange alien worlds through portals.  The details were all pretty crazy sometimes as every new episode was about the new big bad to worry about, but of course it was solved at the end with Drimae and some weird lizard companion she always had.
Jaime giggled a little at him, shrugging, “I mean hey, I never heard of it. But you’d have to really have a pretty awesome movie to impress the amazing Alex, right?”
A soft grumble from the dog as his only response, the cat girl just laughed again, sighing softly, “Alright, we can watch it on the TV in my room. Come on when you’re done, I can take care of the dishes later.”
Without giving Alex a chance to really respond, Jaime stood up and walked out of the room, her tail swishing side to side as it usually did whenever she got to lay down. Despite being so active in her studies, Alex had come to realize that the cat girl was more eager to sleep or lay down than even he was.
He managed to finish up quickly and get up to leave and follow the pale colored feline into her room, not realizing that she had not eaten even half of her food.
Walking into the room, he took note of several things. The lights were off, and she was sitting on her bed and flipping through some channels on her rather large television. Jaime was, after all, the one who paid more of the dorm’s bill than him. It was only fair for her to get the full bedroom, while Alex himself just normally slept in the half bedroom beside the back end of the dorm.
Sitting down next to her on the soft bed, he found himself slipping again just a little. He was tired, but this was a little different. He felt like everything was sort of out of focus, just like before when he had been eating dinner. The boy only snapped back when she gently nudged him, pointing out the Forbidden Realms movie, “This is the one right? ‘Masters of Shadow’?”
Although he was a little shy, Alex couldn’t help but be excited to see it. He hadn’t heard much from the series as a whole, only recently was it brought back up and revived. Apparently, the new series was a lot darker and adult. It made him excited, feeling like a kid again.
With his paws folded on his lap, he nodded a little, “Y-Yeah, that’s it! I’m…wow. I can’t believe this is still a thing. I can’t wait!”
Jaime chuckled and patted his back, resting her hand on his opposite shoulder. “Yeah yeah, I’m sure you can’t. I hope it’s good.”
With that out of the way the cat girl pressed play and after confirming the rental, the move started to show up on screen. Just as the opening scene began to play out, Jaime let her forefinger and thumb rub together gently, producing a strangely luminescent green mist.

The movie was already halfway through, and the main character – Drimae – was trying to escape the clutches of the evil warlock Hallon. In all honesty, while the movie was pretty good, he couldn’t help but feel disappointed. The plot was pretty forgettable, though it didn’t help he kept having those little, sudden onsets of confusion.
The longer it went on, he stopped really worrying about it. He just let himself lean more against Jaime’s shoulder, his head just resting there now with a half-lidded expression. Alex felt so tired, and he just couldn’t understand why. He really didn’t work out that much, did he? Whatever the case, just being with Jaime made him feel better, something about her always felt safe and warm.
Alex seemed to get a little startled though as she ran her hand through his head, a ‘mrrow?’ escaping him out of some strange, new instinct. She giggled, “Just relax, Al.”
Jaime’s words were like an ambrosia, a life raft in the sea of muddled thoughts he found himself in. A nod, slipping against her with a soft yawn. She hummed a bit, “Tired still? Here, one sec.”
With both her hands she’d idly adjust him, shifting to the side herself a little before letting him down so his head rested on her lap. Normally, he’d be asking a couple hundred questions a minute while stammering apologies. Now, he couldn’t deny the comfort even if he wanted to.
Alex blinked a few times, rubbing his eyes with another yawn. It sounded a bit lighter than before, but he didn’t mind it. The stroking over his head and down his side eased away the worries, even as the sweatpants and t-shirt he had been wearing began to loosen.
The strange green mist emanating from the cat girl’s hand seemed to painlessly seep into his body everywhere she touched. It was small amounts, only to keep him from rousing suspicion, but enough to get the job done. Alex didn’t know any better as the green, flowing material slipped into his pores and up into his nose.
As this went on, Jaime began to hum a soft song, something from her childhood she just barely remembered at all. Along with the soothing sensation of light prickling across his body, Alex just kept slipping further into this strangely intense relaxation.
The cat girl pulled her hands away, leaving the canine to whine, “J-Jaime, that was really nice, I…”
He trailed off as he realized that his voice seemed much lighter than before. Perhaps feminine, in its own way. In curiosity he’d slip a hand up and lazily rub his neck a little, finding a strange band of leather there. Along with a simple circular tag, almost like an animal’s collar.
“I don’t…Jaime, when did…wait, this isn’t right, I sound…wei-“As his thoughts started to come together in the mess that was his internal dialogue, Jaime simply tilted his head upwards. She wasn’t wearing her sweater anymore – is that why she stopped petting me?
Just then a moment of clarity, realizing how out of sorts the situation was, starting to sit up, albeit slowly, “W…Wait, Jaime? What are…what’s going on? Why do I sound…girly?”
A little giggle from the cat, leaning back and stretching on the bed. Her body was flawless, the soft swirls of light burgundy on her normally cream-colored fur traced along her soft-looking stomach and full, perky breasts. They were at least a big C-cup, if not larger. But he wasn’t really sure, everything felt like it was moving and his only solace in the storm was her.
She said nothing, just looking at him, her skinny jeans outlining the rest of her perfect body. Laying on her back as she was, it took a little bit of effort to slip them away after unbuckling the belt and button. Alex himself sat, dumbfounded on the edge of the bed.
Slowly and surely, her thick thighs and wonderfully round rear were revealed, at least partially. In the dark, his eyes had somewhat of a difficult time adjusting perfectly for some reason. His mouth was open, but words just couldn’t escape no matter how much he tried.
Jaime lifted her left leg and traced her soft, sweet-smelling paw pad down along the dog’s cheek, moving his head to the side a bit, “Just relax, Al. Come here, and I’ll make it better.”
While in ordinary circumstances he’d be more worried than aroused or excited, he just nodded and turned on the bed so he was at her right side. Safe, tucked away against her so the world couldn’t poke at him without getting past her first. A soft mewl forced its way out of his muzzle.
“Shh, just come lay down with big sis. She knows what’s best for you.” Her hand caressed the side of Alex’s face, though he managed to question in the strange, new voice, “B-Big sis? But…you’re not my sister…”
Perhaps the slightest twitch of a frown on her face, but she’d relax quickly again and continue to gently stroke and rub his face, his head, one thumb giving a light brush over his eyes separately. The longer her hands were on him, he felt an odd sensation of softness. Like she was…molding him.
Although he tried to speak again, she’d stick two fingers into his mouth, uttering a soft command, “Suck. No need for your words.”
Though Alex wanted to say no, or anything but as she said, the dog boy found that his mouth was already gently suckling on her two fingers obediently. Tongue gracing over those two delicate fingers, shuddering at the flavor. It carried almost a peach undertone, maybe her body wash.
Those two bright hazel eyes were narrowed with focus, her free hand rubbing under his chin, “There we go…you’re a little tough, you know? After this, it should be a lot easier though.”
Whatever she meant by “this” was lost on Alex, though he did notice that his face felt less tingly than it did beforehand. The green mist flickered under a strike of thunder nearby, only being seen now that he was paying attention, what did she do to me?
Thankfully his thoughts were still mostly his own, but otherwise he could physically do nothing as Jaime pulled away and wiped off her fingers on his shirt gently, “There we go. Now, are you ready to see your new, pretty face?” A little mumble of a question, then she’d reach behind him to take a small mirror from the shelf.
In the mirror is what looked like Alex. At least, if Alex was a cute-looking cat. His face and ears seemed to have shifted about with ease, now much more closely resembling Jaime’s in shape. A definite feminine tone to it, his eyelashes longer and incredibly soft-looking fur. Well-kept, and bright hazel eyes.
The image that stared back at him was what started to wake his body up with trickles of panic down his spine, “Y…You changed, m..me…what…what’s …J-Jaime, I’m scared…”
Even as he tried to give some kind of strong, or angry response, what returned was a mere mumble. Moreover, it was not in his own voice. No, instead it was in that soft and apprehensive cat girl’s voice. A hard swallow, and the weight of the collar around his neck felt like a hundred tons.
A little giggle, the other cat girl nuzzled him, cheek to cheek, “Just relax, little sister. It’ll feel so much better, okay? Big sister’s here. I promise you’re safe.”
As unwanted as the words and promises were, they still made his heart flutter and his body relax, a little mewl let loose in response. With no further resistance, Jaime would slowly let her hands trail over his covered chest, along with the other down to grope at his rear, “You’re very cute, Alphinese, but you could be a lot cuter. Don’t worry, big sis knows how to help.”
Alex gently nuzzled into Jaime, mostly worried about their mental state more than anything. He wasn’t entirely sure what was happening, but Jaime kept assuring him that it was okay. Even if he didn’t want to move, he couldn’t besides little, hesitant shifts on the bed. Everything at least felt nice if nothing else.
Her face scrunched up a bit, “Mm, I’ll have to do away with this real quick…” Their finger dragged up along his front, accompanied by a light tearing sound. Her claw had easily slipped through and cut the fabric in half, leaving his bare and lean torso to be exposed.
Although Alex had worked rather hard to get where he was, his body wasn’t exactly the absolute picture of masculinity. Not necessarily feminine, but his torso had a nice lean musculature to it that meant he was good at running down the football fields and avoiding getting tackled to the astroturf.
Meanwhile that strange mist from earlier was worked into his skin through the clothing, his chest and thighs slowly beginning to warm up. A little, sudden gasp as the sensitivity on his chest skyrocketed. He glanced down, watching as her hands stroked, rubbed, and squeezed over his normally flat chest.
Before his eyes, the flat pecs started to soften in shape under her careful work, the carefully toned muscle seeming to just melt and reform at Jaime’s will. Every touch was measured and methodical, seeming to work his body like clay. A little rub here, a squeeze there, changing his shape as easy as pottery. A meek moan found its way out of his throat, surprising him, but she didn’t seem to care.
“Little Alphinese feeling needy? Don’t worry little sister, I’ll take care of that when we get to it. Just try to not get too eager.” Her voice was calm, warm, and even a little scolding.
Despite not caring, his ears twitched and lowered over his newly formed head. She didn’t respond, too busy working on his new breasts. The bump on both sides was forming nicely, already at a smooth A-cup without much time. More and more of that strange green mist seeped inside and helped her pull, push, and mold. Another little moan and quiver down his back as his body was changed.
With a triumphant little giggle, Jaime gave his new small breasts a soft squeeze, “Feel good, little sis?” The answer was, of course, another mewl of pleasure and wriggle on the incredibly soft bed, “Well, I can’t wait until we get to your bits down below then!”
There was a few moments of uncomfortable shifting on the bed, Alex feeling himself being moved up just a little from Jaime lifting him under his shoulders so they were more properly at face-to-face. The loving look of adoration on the cat’s face was so incredibly heartwarming, the dog”boy” almost had a hard time wanting to stop.
Her bright hazel eyes traced over Alex’s body for a moment before leaning in to kiss him. It was a sudden thing, something he started to comprehend only a half-moment before her soft, plush lips pressed into his own. He expected her to be a little pushy perhaps, but she took her time coaxing and running her tongue against his pouting lips. Eventually they opened to accept his big sister’s tongue, a soft moan at the taste and texture of their tongue playfully running against his.
It was a moment of heavenly pleasure just from the kiss alone, not noticing the green mist as it almost poured into her for a few moments. Then, just a soft meeting of their lips and tongues, the smaller of the two wriggling a little and conforming against Jaime’s will. He felt so small and weak as her hands trailed up along his arms, squeezing them with that strange magic. Molding them down, leaving them dainty and perfect for a cute catgirl like he was becoming.
Alex didn’t notice, but his fur was already completely changed to a pale brown, dark swirls of rich chocolate-colored fur over her belly and along her paws and back. A few dots of that deep brown here or there, and she was looking like a treat for her new big sister to gobble up.
He felt some of his sensations return to his extremities, at least his arms. They raised up a little, and Jaime’s followed suit, holding his now thin, soft paws, leaving him weakly quivering against her. Most of his strength was just gone now. Nothing left except the soft beauty here, besides the regular level of strength someone of his new body shape would have.
Jaime didn’t have to say much as she eagerly lapped and tasted everything inside Alex’s mouth that she could, letting her hands moving without much effort, spreading that strange green mist along her sister’s sides and hips.
No matter what Alex wanted, he could feel his lower half start to shift just like his chest had. The tickling and nearly sickening sensation of his sides melting inwards slightly, creating a perfect, slow curve to keep up the petite form. Jaime’s hands sculpted her while their tongues mingled and tasted one another. His muzzle twitched a bit, the newish whispers tickling both of their faces as the kisses pushed against each other more eagerly.
Over his newly shaped hips, Jaime’s paws were able to completely reshape his body, organs and bones changing like flowing water. A soft whimper, managing to pull himself away from her lips. They captured him every time their lips met, finding it hard to really do anything besides relax into it.
“What? Don’t you like your big sister’s kisses?” Her voice was a deep, lovely purr that dripped like honey in his ears. Alex whined weakly, his ears flicking and lowering against his head, “N-No I d...I do, but...I-I don’t want to be...a g...girl…”
There was a mere soft chuckle, taking on of her paws to rub along his muzzle in that comforting way that made him feel weak and lean into it gently, “Sweet little Alphinese, you are a girl. Don’t be worried. Big sister loves you, and she’ll love you forever.”
Alphinese opened his mouth for a moment to respond, only to feel a weight in his throat. What was his name again? A few blinks of his eyes and he’d reach up to gently rub his head, “Wait, J-Jaime, what...what’s…”
Nothing but a soft coo, kissing Alphinese’s cheek as Jaime held their head with one hand, sending the other down to stroke and rub along their hips and stomach. It left his body to be significantly less muscled, instead resembling a cute and soft-looking catgirl. She had larger hips than before, a slight bounce added to her rear from the mist and Jaime’s will. She...he felt himself slipping and quivering against his sister.
Jaime finally leaned back a bit and giggled at his new form, being at least a couple inches less tall. His body was alien to him, being so incredibly cute looking he almost had trouble thinking it was still himself. He was a strong quarterback. He had jock friends, he was at least five foot ten. Now? None of those things.
He almost felt sad to have lost himself, but the drifting of a paw from his big sister to his shorts had him gasping. Her claw made short work of his lower clothing, slicing it open with ease. It let his length pop free, hard and eager. When did I get so aroused by this!?
The catgirl wasn’t at all surprised by this, eyes still half-open. Her paw would gently grip his length and start to stroke gently, giggling softly to herself, “You’re so cute...don’t worry sweetie. Big sister will make sure to get rid of this last part. Then you can be my perfect little sister. Just relax…~”
His dick was already leaking cum, almost instantly upon contact. However, there was no glorious climax. Just a sudden spike of pleasure as he was slowly worked over, his dick leaking a steady stream of cum and..something else. A vital part of who he was, only enhancing the pleasure further.
There was nothing he could say. He wanted her to touch him so bad before, and his whole body was so weak he could barely move. Whatever he’d eaten before with his food, or had put into him with this apparent magic, made the world feel uneven and twisting. Even if he’d gotten up, he’d be falling over constantly, not to even mention because of his inability to get used to this new body just yet.
His toes curled a little, whimpering and moaning against Jaime as her other hand quietly holds his head, letting those misty green wisps slipping into his head through his ears, nose, and even seep through his slowly shrinking cock.
The canine cock was quickly shrinking away the more arousal he leaked out, seeming to come in copious amounts, a nearly never-ending orgasm. A soft whine, jerking a little as a particularly larger dribble, the catgirl shushing him, “Shhh, little Alphinese, just relax...enjoy it.”
“It feels g-good...please, just...s-st...nnnnh…” He couldn’t manage to get it out. Did he want it to stop? Alphinese couldn’t even remember his name anymore, it felt like it was leaking it out through his length, everything from his past seeming more and more vague. What was his last name? His family home? He couldn’t even remember where he lived, besides with his big sister, Jaime. But that didn’t feel right, and yet, there was nothing else.
“You’re such a good girl, little sister. Just letting big sister take it all away...just enjoy it. You’ll never feel something like this again, after all. Once we’re done, you’ll feel nice and happy, I promise.”
She...he? Was the cat even a boy anymore, with his dick shrinking so small now that he could barely see it without craning his neck towards it. 
Alphinese was his name, it always had been, as far as he remembered. Despite knowing that, it simply left him feeling confused, on top of getting more and more aroused. A soft flinch and whine, his dick twitching in Jaime’s paw.
She felt so hot, her skin was tingling all over and her fur was all on edge, tail twitching and swishing against herself. Jaime continued to coo at her and even licked her little sister, starting to groom them gently while jerking off her cock. It was miniscule now, barely even much of anything beyond a sensitive little clit.
“Now, little Alphinese, I need you to tell me how much you love your big sister. I want to hear how much you like being my sweet, lewd little sister. Then, I’ll take good care of you for as long as I live…”
Alphinese moved her head to nuzzle against her big sister’s neck, groaning into it, starting to speak just as they commanded, “I-I love you, big sister...I love you so much. I need...I need you to d-do this, please, I’ll be a g-good little sister…”
It didn’t take much longer. Feeling that draining from her balls until they disappeared entirely, now from her head down to her slowly disappearing maleness. With it all fading, there was nothing but her big sister left as her eyes rolled back, hips twitching.
Alphinese blinked her eyes a little as everything came back into focus after the short moment of unconsciousness. She looked over to her big sister, nuzzling into her gently with a soft whine, asking for attention.
Jaime giggled softly, “Do you feel better, little sister? You certainly let out a lot of yourself…”
“Yes...I feel so much better. Thank you, big sister. B-But what about my pussy?” Her voice seemed to dip a little, mostly out of shyness. She couldn’t be completely lewd all the time, otherwise she might get in trouble.
The larger of the two chuckled, kissing her cheek, “Don’t be silly...it changed as soon as you were ready.”
A few little rubs at Alphinese’s new, puffy pink pussy lips and there was little she could do but gasp and moan, a shiver down his back and tail, “A..Ah, thank you, big sister...c-can we play later? I’m kind of sleepy…”
With a soft sigh, Jaime would nod, “Of course, sweetie. We can take a nice rest. Just relax.”
As the two catgirls cuddled up naked, the thunderstorm continued to rage outside, and the movie slowly faded out to darkness of the credits.
