Shinigami Swap(Rukia Ichigo Tf Tg MtF FtM)

It hadn't been easy for Rukia to admit it to herself, considering her pride, her experience, and how hardheaded Ichigo could be whenever she needed him to budge on anything, but the truth was, she reaaaally wanted him. It had started out with a few weird heart flutters after he had saved her the first time, flowing into some dreams that over the last few months had gone from tender, to steamy to doing the laundry when she woke up. It wasn't a fun thing to admit, her attempts at ignoring it only making the dreams come back hotter and steamier as time went on. Worse, it seemed like Ichigo was completely unaware of her feelings, a pang of jealousy frustrating her whenever he left to hang out with Orihime or Tatsuki. She wasn't sure which one would be worse for him to end up with, Orihime having things that... well she couldn't compare to all that firepower up top. B-But guys liked slender petite girls too! But nooo if he ended up with Tatsuki then it'd be like she'd lost to someone in her league, which meant she could have had a chance!

It was weird how she could easily stab a guy and give him all her powers with barely any hesitation, yet the thought of asking him out just made her... GAH! It was during one of these mental self arguing sessions that Urahara had given her a poke from his shop, brandishing a set of pills.

"Rukia, are you in distress and need a convenient solution requiring experimental soul drugs?!"

"Uh..."

"Perfect! Say no more because I can tell from that flush on your cheeks, the pitter patter of your heart, that time Yoruichi heard you moan out Ichigo's name while she was visiting the Kurosaki residence in your sleep that you could use some help in turning our carrot haired wonderboy your- NNFF!"

Rukia took her punching glove off, the veins in her temple bulging as she angrily replied, "I have no idea what dumb ideas you may have made up, but I'm not desperate enough to-"

"I can help you get Ichigo..."

He had to gasp it out, annoyed that she had bruised his chin, but the experiment was more important to him.

"Eh hem, now that you're actually listening and not attacking this helpful samaritan who only wants to-"

"Just spit it out already!"

"Aww you're no fun. I forget you're not like Ichigo and aren't naive enough to have patience. Fine, this pill will switch the reiatsu's of whoever eats the two halves, creating a possible skill swap but importantly infatuation with each other. Mostly because I think said spirit energy longs to return to its original body, but I'd like you to give half to Ichigo and you can give me the results if there's any side effects."

It was tempting, especially since the idea of an Ichigo horny for her had played heavily in her last few fantasies.

"...fine screw it. Hand it over I'll give you your dumb results."

He didn't say anything, just smiling his shit eating grin letting her know he was making fun of her in his mind. It didn't take too long for her to develop a plan since Ichigo usually just guzzled down any drink he had in front of him since he was always in a rush. It also helped that his dad was out that day and the high school was closed down after a gas leak/hollow attack from a few days ago so while his sisters were out, they had some free time.

Actually considering how convenient all of this was lining up, Rukia wondered if Urahara had somehow had a hand in this, or was just waiting for the right time since she did Gigai maintenance fairly often there. Whether it was luck or preplanned, it didn't matter much as she poured a glass of orange juice and bit the pill in half, swallowing hers and watching his half fizz away until the juice had gone still again.

"Ichigo! I poured some juice but I'd rather get some chocolate. Could you spare me some petty cash?"

It didn't take long to hear his footsteps rushing down, clearly agitated.

"Look Rukia I'm not made of money and you can't just waste juice cause you have a sweet tooth!" There was a buzz in Rukia's stomach, which was either from nerves or the pill in her bloodstream, making her reiatsu swirl about and slowly unstick from her gigai. Shrugging her shoulders and pretending to be calmer than she was, she went to dump it down the sink, knowing Ichigo would grab it from her and down the whole thing. Her heart rumbled in her chest when his hand brushed hers in the grabbing, Rukia's eyes lighting up as she smiled nervously, ready for her fantasy to come true. Her eyes were stuck on the bobbing of his throat, each bounce meaning more of the dosed juice was working through his system, and any second now something would-

"HNNGH!"

"HNNGH!"

Her fantasy felt like nausea and vertigo, both her and Ichigo stumbling about as their reiatsu switched, their energies stuffing into containers completely unsuited to their purpose. In most talks about reiatsu in Soul Society or in general, they usually used a water metaphor, since it flowed and ebbed, but while water usually shifted to fit its container, as the essence, the core of a person, for once the containers the ones shifting to match their contents.

"Rrghh n-need to go to the bathr-OOHM!" Ichigo bolted, nearly shattering the glass as he gripped his stomach, his innards shifting about, a hard to trace warmth pooling in his heaving stomach as it felt prickly, ticklish, pleasant, disgusting, just wrong all around. Rukia would have told him to stop, but she wasn't faring much better, her knees wobbling as she slowly collapsed to the ground, panting and pawing at a strange sensation in her crotch.

It took a bit to realize it was arousal, pure, pulsating pleasure so condensed and alien, that it didn't even register as something enjoyable until she moaned, slipping her skirt and panties down to see what the hell was going on. Liquid was dribbling out, trickling down her thighs in a consistent flow, no ordinary wetness as the usual swelling she felt when aroused seemed to be taking itself to impossibly absurd levels, her lips looking really puffy, but what stood out the most was the swollen clit that was peaking as she spread her legs wide. Closing her eyes, she could feel Ichigo's reiatsu in her, slipping into her clit, her womb, filling her erotically as the organs squelched and shifted inside. Shit she really shouldn't be liking this, it was wrong and the way his energy kept building up in her clit made it feel like any second she'd-

"UGH! F-FUUUUUCK~!" A veritable explosion of liquids shot out her pussy as as her clit was slammed internally, swelling further and further as her cervix went from canal to crater, a meaty wall thrusting up behind her rising clit as the sensitive nub expanded to a spongy mushroom. It felt like the most thorough and intensive fucking she'd ever had, the rising clit throbbing against the muscles of her vagina, scraping against each and every fold as her knees slammed together, the cold air of the room driving her mad with pleasure as a puddle of juices slurried from her parted pussy lips. Rukia cursed and came, screaming as her sensitive clit rubbed against her thighs, sliding out as it barely resembled the hard button it used to be, the muscled shaft pulling out more and more of her vagina until it fully thwacked out, the whole thing throbbing and leaking excessively until the flow stopped, a few driblets plinking from a slit in her exterior clit as it fully bloated, Rukia groaning as she saw a raging erection between her thighs, screaming as something hot dug into her from the base.

Ichigo barely made it to the bathroom, tripping up the stairs and scrambling on hands and knees before that twisting in his stomach turned really weird, his jumbled up feeling organs twisting and slithering down, something snakelike wrapping around his balls, his usually stoic face blushing with a yelp as he felt two short pricks let him know his balls had both been speared by something that was buzzing against his most sensitive bits. It was the strangest erection he'd ever felt, familiar in the weirdest way, his subconscious probably picking up on this not being the first time Rukia's reiatsu had shoved itself into him, though rather than as a catalyst, this energy was corruptive, insistent.

Something was internally starting to jerk his cock off, Ichigo unsure of what to do, moaning as he felt his cock swell. The chaotic swirling had settled into a more oppressive compression, a feeling like a vice grip or corset pulling taut against his spine, his sides, the muscles spasming as the stroking intensified.

"Ahh mmph nooo c-can't NNGH ohhh~ GAWWWD!"

SCHKRICK

The clenched muscles of his cock relaxed splattering his pants with his balls' contents in a messy puddle. Ichigo didn't understand what was happening, orgasms rolling through his bothered cock one after another as he was left squealing and grinding against the floor, the soft fabric of his underwear feeling rough and gritty under the increasing sensitivity, his balls pulling tight once they ran out of juice, something else spilling out instead as his sides and skeleton gave in to the constricting pull of reiatsu. It felt like he was melting, cumming away his existence as each release was a buckshot of sticky fluids, his back cricking inwards, his sides cinching a little more with every violent spasm. His clothes were getting baggier, inches shoving down and out as he spasmed, trying to make it stop as he drowned in a sea of drenched fabric.

Rukia felt arid down below, not desert dry, but like the searing, burning bubbling of a volcano, reiatsu pooling in her ovaries, pushing the fleshy bulbs up and out. It almost hurt how good it felt, her shrieks undulating as she felt her ovaries melt and slither, inverting her fallopian as the trapped reiatsu thickened and wriggled, something thicker and gluey sliding out her ovaries as they slammed together, a white spray misting out her cock as a leathery sack flopped out, the slippery feeling of semen dribbling down her thighs. Her nose flared, Ichigo's scent washing over her, dizzying her in the lust as her mind pieced together what was happening. She wasn't sure whether she should laugh or cry, her body deciding for her as she moaned, the weird sensation of her balls filling up still making her female centered nervous system tremble as if it was being filled, her cock spasming as she came. Except what her balls pumped out didn't go out, but in.

"H-AHHHH~! Ohh oh ohHHHH~! I-IchigoooOOOOH!"

Masculinity was dribbling into her thighs, burning through what fat she had before pooling inside her toes, her feet wiggling before popping, socks tearing apart at the seems as her toes grew thicker, arches flatter, her heels busting through in identical thickness as callouses formed over the growing flesh. It felt strong, hard, sexy, Rukia groaning as her cock backfired again, now flattening the curves of her calves as the bones shattered, reiatsu filling in the cracks to leaving them much longer than before. By this point Rukia had given up on fighting back, sure Urahara would fix this somehow and deciding it would be wasteful not to relish this opportunity as she swaddled her cock between shrinking thighs, giving it one last thighjob before her thighs deflated, a dull throb at the back of her hips resolving itself with a violent snap that forced her head back in a euphoric shout, her wide hips shrunken, knees now separated by parallel increments.

Ichigo had no aha moment, his body hot and struggling to untangle itself from his oversized robes. By the time he freed himself a solid foot had spurted from his cock, his back dimpled deeply, his sides looking emaciated as he flopped down naked. He hoped the cold tile would cool his sweat covered frame some, but instead it sent his nipples sparking, swelling against the cold tile as he flipped onto his back. Once they had hardened, he couldn't get them out of his mind, both nipples pulsing with a newfound life, rising before his eyes into pink inflated discs that just begged for attention. In a moment of weakness, he touched one, regretting it immediately as a goopy load spilled from his cock, groaning as his back finished shrinking, popping into a tight curve that thrust his hard nipples out, his unhealthy looking sides finishing their crunch into sexily curved perfection.

He couldn't stop touching his waist, sighing as his abs melted into him, shooting out all at once as his gyrating midsection softened. It felt smooth, cuppable, sexy, the pleasure lulling him again towards his nipples, their throbbing existence a siren call to his mind. It started with circling them, his shoulders rounding as he flinched through the tenderness. Next came the real exploration, prodding them, fondling the tips, pinching the sensitive nubs as reiatsu began blissfully slipping in, rewarding him for his lust with more potent pleasure. Soon he was giggling, moaning, one hand rubbing his cock as it shrank, the girly, soft fingers teasing out the releases he needed. Sweat soaked his drooping hairdo as something orange was mixed in with the white of his releases, his hair darkening, losing its color to a pitch black, each strand oiled and conditioned to a shining gleam. It was all lost on him, the growing hair, his rising moans, the subtle shifts in his face, cumming hard as reiatsu turned to fat and bolstered his chest into a pair of perky, pert breasts.

"Ahhh~ Ahh fuck oh gawwd y-YESSSS~!"

It felt too good to stop, his cock rewarding him in a feedback loop as goopy, masculine remnants were drained, a black cowlick scything past his eyebrows and lashes, infecting them all with the color as his eyes stung and bulged. He could feel his corneas shifting, breaking against the sockets as they widened. All he did was beg for more, almost cheering as his shoulders slipped inwards, rounding down as their unneeded breadth sent his kneading hands out, her face buzzing. Once more his cock tensed and came, his subsequent moan a match for Rukia's if he had been paying attention, his face now feeling almost like a poorly applied mask. It suctioned back in, crushing his jawbone, shrinking the nose, jet black hair tickling his button nose as both hands shot down to his cock, the whole thing trembling as the real climax was quickly approaching.

Rukia was in a similar position, happily moaning in a bassier tone as masculinity pumped straight from her balls and into her body, flattening her booty into slabs of flat glutes, her stomach almost aching as the muscles spread and hardened, giving her belly a toned fitness that hardened into a veritable diamond as reiatsu began squeezing into the gaps of her spine, winching her height up in creaky, disjointed spasms. She didn't want it to go so fast, hoping to bask in the changes some more, not imagining this exact scenario when she had dreamed of grasping Ichigo's dick and making it cum, but it was impossible to stop the orgasmic waves that built with every passing backfire.

It was all the little things that really got her going, the sensation of tiny hairs prickling out all over, the way her breasts seemed to fizzle away as muscle absorbed the fat, transferring her two sensitive nips down to her cock as her stubby arms snapped downwards. Reiatsu flattened her arches, filled in her curves like muscled cement until "her" was barely applicable. HIS balls felt massive, slowly building up their true load as his shoulders slammed outwards, broad strength filling every crevice of his toned body as he jerked faster and faster, trying to condense months of want and need into a few minutes before the tell tale buzz of reiatsu was in his fingers. Rukia groaned as his jerking hands turned thick, strong, muscled, his cries rasping in his throat as something agitated the middle, thumping up and down as his cries gained an angsty rasp, orange bleaching down the black as he gave one final stroke down.

"Oh OH YEEESSSSSS!" He finally felt release cum to him, gasping as a spray of viscous, semen filled cum sprayed from his cock in a single glorious release that drained him of Rukia, his face tingling as bones popped and shifted, his hands moving up to feel the hardening contours, the added jaw jut, his shrinking lips, all of it ending with a contented sigh as his cock flopped down. The only sign of who he had been was his hair, longer than the real Ichigo's usual cut as he contemplated how final that release had felt. He didn't think it was possible to even get his cock up again from its limp rest until he heard his previous voice screaming with need, both his lips and cock twitching up in anticipation as he followed it up the stairs, finding a half finished Ichigo pressing down on his shrinking cock in a puddle of cum, screaming as he fucked himself into womanhood.

He had never once before thought of his own cock as inadequate, but Ichigo was cursing it as the supernatural stroking built up more need than the thin slit could release, his body thrashing about as the pressure built, shattering his hips apart, bloating his ass and thighs with reiatsu that only made it all the more tempting to gnash together against his cock. Briefly his consciousness recognized the shadow of something approaching from the door, but the only approach he cared about was the climax he wanted, no needed to happen as he went from jerking to pressing.

At first nothing happened past a dull pleasure at the base of his cock, building and building the harder he pressed. Then, that slithery shifting feeling returned, glomping onto his cock internally as a clear shot arced into the sky, his desperate masturbation turning more feverish as his cock began to recede. It all seemed to happen in a blur, or stretched out to infinity his mind racing between two extremes of time dilation as the tubes that had first pierced his balls jerked, a sudsy, slippery solution sputtering out his cock as both balls slipped inside a narrow chasm that split them in two and massaged them into unrecognizable shapes deep inside.

The need was growing, both palms pressed flat onto his cock, his feet twitching as cum covered their shrinking, arching forms. A subconscious cry built in the back of his throat, his petite form writhing as his condensing cock soon became too sensitive to touch, throbbing and leaking as it pulled inside, the tip sticking for a second, caught on the lip of his puffed up lips before suddenly rocketing inside as his head shot back, clear cum pouring out as SHE screamed out, "R-RUUUUUUKIIIIIIAAAAAAH~!!!"

She heard her voice groan, her eyes drifting to an exact copy of herself, her mind vaguely registering with a glance that in the mirror that she had become Rukia and Rukia had become, h-had become... incredibly sexy. Ichigo shook her head, staring confusedly at her loins, feeling heat race up them the more she thought about her actual body, the two reiatsu's magnetized towards each other as Rukia pulled Ichigo from the wrecked bathroom floor and dropped him onto a couch in the living room. Both were blushing, feeling an intense need as they looked at each other, magnified by the clearly audible aroused panting as they silently stared, Rukia at his own breasts, Ichigo at her own cock. Tensions rose, and then suddenly broke all at once when Rukia couldn't take his erection's throbbing anymore.

The only sound Ichigo made was a surprised quivering yelp as Rukia tackled her, his cock sliding into her pussy like it was meant to be in there, his mouth soon silencing any doubt as the two Ishigamis had sloppy, passionate sex, groaning as reiatsu replaced cum, their bodies shifting, crunching, neither knowing where they began and the other end, genitalia messily sliding in and out of one another in transformative bliss, the two utterly enraptured as they twisted around each other, not a care in the world for-

DING DONG

Yuzu and Karin only had a half day, both eager to return home and relax, though they grew worried when they reached the doorstep and heard the sound of some people clearly in distress from how loudly they were moaning, some truly disturbing sounds accompanying said moans. Karin thought they sounded like Rukia and Ichigo, but it was hard to tell since the voices kept kind of shifting weirdly. While they were arguing over what to do, Yuzu had accidentally leaned on the doorbell which after a few more seconds and two really loud grunts suddenly silenced the groans and turned into a frantic sort of fumbling before the door opened, Ichigo and Rukia both looking flushed and flustered in a clearly disheveled state.

"Um h-hi there Yuzu, Kari-"

"What the heck were those weird noises?!"

Rukia had hoped they wouldn't have heard anything, trying not to flinch as the last of Ichigo's cock inverted between her thighs as cum dribbled down into her stockings.

"Oh those, we were just... realizing we were late to school and uh, arguing really hard over whose fault it was."

Her attempt at a genius cover was immediately shattered.

"Wait you two haven't left for school yet? I thought you had a gas lea-"

"Th-That's right! Which is why we have to go over there right now and help them out, right Ichigo?"

"HFF HAH uh... yeah. School. Arguing. That's all."

"Anyways we have to get going... right Ichigo?"

He gave a beleaguered nod, still reeling from everything that had happened as they started walking. When they were out of sight, his hand casually wrapped around her hip, while Rukia tugged at a hand, unable to hold back her joy. They'd definitely be editing the report to Kisuke, making sure to not get too graphic, but both agreed on one thing before they left. To celebrate their new relationship, they'd be buying out the whole stock.
