She's now Poison Ivy's submissive sidekick

"Red? Hey Red, why're you lookin' at me like that?"

The reason why Poison Ivy was staring slack-jawed at Harley was because she hardly recognized the woman in front of her. She still had the same blonde pigtails, but the tips of them were no longer dyed, instead retaining their natural blonde color, and they were tied back not with hairbands but with tiny vines, the one on her right having a small cluster of red berries growing on it. Her outfit was completely different though: the crop top and hot pants were gone entirely, replaced with what looked to be a leotard made of leaves, with a low v-neck that left her shoulders and cleavage (which was at least good cup size larger than it was before) exposed. Around her neck was a choker made of intertwining vines, with another red cluster of berries hanging from the center like a dog tag.

But the biggest and most noticeable change was her skin color. It was not the pale ghastly white from before, but it also wasn't the pinkish 'white' that would be her natural skin color. Harley's skin was now a light green color... the same color as Ivy's own skin.

This new Harley frowned, and put her hands on Ivy's shoulders, "You're scarin' me, Red. What's going on?"

Ivy blinked, and managed to croak out, "Harley... what... what happened to you?"

Her lover raised a brow, obviously confused, "Harley? Damn, ya haven't called me that in... well, forever. Not since we were just gettin' to know each other."

"I... no, that's not right," Ivy said, "That's who you are... Harley Quinn..."

"The hell are you talkin' about, Miss Ivy?" Harley said, "That's not me. I'm Holly!"

"That's what I said. Harley. Wait a sec, Miss Ivy?"

Harley sighed, "No, not Har-ley. Holl-y! H-O-L-L-Y. Freakin' accent... then again, that's sorta what gave ya the idea in the first place."

"H-Holly?" Ivy muttered, trying to process this new information. That would certainly explain the red berries... and now that she had a closer look, she could see that the majority of her new costume was made of holly leaves.

"There ya go!" 'Holly' said with a grin, "That's the Red I know and love."

Holly went in for a kiss, but Ivy, going from stunned to completely freaked out, shoved her away and stood up, "No! No, this isn't right!"

Holly let out a squeal as she fell back and landed on her butt. Then with a frightened look on her face, she shuffled forward on her knees and prostrated herself, allowing Ivy to see that the back of her leaf leotard had almost no back to it, exposing her shoulder blades and bare back all the way down to just above her tailbone. Ivy also couldn't help but notice her butt, while covered, seemed to have gotten a slight but noticeable upgrade as well, being a tad bit wider and more round than before.

"I'm sorry Miss Ivy! Whatever I did wrong, I'm sorry, please forgive me! I'll accept any punishment you-"

"Stop that!" Ivy snapped, disturbed at seeing Harley be this submissive towards her.

"Yes, Miss Ivy," she said, sitting up but still remaining on her knees, "What do you want-"

"Shut up," Ivy said, and Holly's mouth immediately snapped shut. Ivy then turned to Inara with a murderous glare, "What the fuck did you do to her?!?"

"Me?" Inara asked, placing a hand on her chest with faux innocence, "I didn't do anything but fulfill your wish."

"This isn't what I wished for!" Ivy shouted, gesturing at the blonde plantgirl. Holly let out a squeak, then covered her mouth in obvious shame at her disobedience.

"Not directly, no," Inara said, "But this is what your wish led to."

"How did my wish to keep her away from the Joker lead to... to her being like this?" Ivy asked.

"Oh come on, don't play ignorant," Inara said with a frown, "We both know Harleen Quinzel had a few screws loose before she ever entered Arkham. Joker may have taken advantage of that and made it worse, but she was always going to latch on to the first person who showed her the love and kindness that she lacked in her life up until that point. And with the Joker not being that person, someone else was inevitably going to fill that void in her heart."

"And... and that was me?" Ivy said, looking between Inara and this new Harley... Holly... whoever she was now.

"Correct-o mundo!" Inara cheered, "Now she's your sweet little Holly, as madly devoted to you as she used to be with the Joker! Sure she's a bit more subby now, but-"

"Change her back, right now!" Ivy snapped, "I... I wish she was back to normal!"

"Normal...?" Holly squeaked, "Wh-What do you mean, Miss Ivy...? I thought you liked me the way I am now...?"

"No can do," Inara said with a smug grin, "I grant wishes to make things more sexy, not less. And this is definitely an improvement to your relationship over what you had before... I mean, if you thought the stuff you did with the old Harley was kinky, wait until you try out the new version."

Ivy was about to respond to this, to tell her to fuck off, but a small whimper from the ground made her pause. Turning around, she saw Holly looking up at her with huge puppy dog eyes, that Ivy now realized were now green instead of their usual crystal blue. And what's worse, they were watery and on the verge of tears, a sight that always broke Ivy's heart to see.

"Oh, babe," Ivy said, dropping to her knees in front of her and cupping her cheeks, "Hey, it's okay. None of this is your fault."

Holly sniffled, "Yuh... Yer not angry with me?"

"No, of course not," Ivy said, pulling her into a hug, "I love you, Harls... and I'm going to fix this."

"F-Fix it?" Holly said, "I... I don't wanna be fixed though... I wanna be with you."

"I know, and I want to be with you too," Ivy said, pulling away, "But not like this..."

Holly frowned and cocked her head, "But... but ya told me it would be better if I was like this. That I... that it would be the safest way for me to be with ya."

"I... I did?" Ivy asked.

"Yeah, ya did," Holly said, "What's wrong with ya, Red? A few minutes ago everything was fine, but now you're actin' all weird..."

"I'm acting weird?" Ivy said incredulously, "You're the one who-"

"Stop trying to explain it to her," Inara said with a sigh, "She doesn't remember the old reality. Only the new one where she's you little pet slash sidekick slash girlfriend."

"Why... why the fuck would I do this to her?" Ivy said, "I would never... never change her so completely..."

"The you of the old reality wouldn't, because you didn't want to be like the Joker," Inara said, "But the you she knows didn't have those feelings holding her back, so- you know what, here, this'll be easier than explaining it all to you."

"What would be... wait, what are you-" Ivy started to say, before Inara placed an index finger on her forehead, and everything went white.

She was in her old hideout, from years before she was able to get the apartment. It was the same shitty mobile home that she remembered, kept safe by virtue of being smack dab in the middle of land too toxic for people without an immunity to poison to set foot in. Thankfully, Ivy had just such an immunity, and the formula she had just finished at her makeshift biochem lab would grant that immunity to another person... among other things.

She finished filling up a syringe, saying, "Are you absolutely sure you want to go through with this? Once I inject you with this formula, there's no going back."

"I wouldn't be here if I wasn't sure," a familiar voice said from behind her, "If this is what I have to do to be with you forever, I'm ready."

Ivy flicked the syringe and gave it a small squirt to get rid of the air bubbles, then turned around to face the source of the voice. Laid out on the bed was Dr. Harleen Quinzel, still in her lab coat, red dress, and glasses. She was restrained, held in place by strong, thick vines wrapped around her body like a cocoon, but she didn't look scared or even nervous, instead having an enthusiastic smile on her face.

"Alright then," Ivy said, stepping up to the doctor, "Remember, this is only an approximation of what made me what I am now. I have no idea what part of the mixture that spilled on me actually gave me the power to control plants, but this at least should make you more plant-like and able to give off a bit of your own poison..."

"...and make me immune to your poisons, right?" Harleen asked, before coughing painfully.

"Yeah... and the ones that are around here," Ivy said with a frown, "Which are already starting to take their toll on your body, so we better do this now."

"I can't wait," Harleen said dreamily, "First thing I'm gonna do once I'm transformed is make out with you so hard! It'll be nice to finally go all out with you and not have to worry about goin' into anaphylactic shock from your poisons."

"I know," Ivy said longingly, "I'm excited for that too. But I don't know if you're gonna feel like doing much of anything afterwards. If it ends up being anything like mine, this transformation is going to be... intense."

"It doesn't matter. I'll go through anything for you, Red," Harleen said with a smile, "I love you. More than anyone and anything in the world."

"I love you too, my little Holly," Ivy said, stroking her cheek gently, "Now open wide."

Harleen obeyed, and with a gesture Ivy summoned a smaller vine to go over her mouth and act as a gag for Harleen to bite down on. While she wasn't thrilled about the plant getting hurt when the psychiatrist's teeth inevitably dig into it, it was better than Harleen biting off her own tongue and dying during the transformation process.

Ivy took a deep breath, steadied her hand, and plunged the needle into Harleen's neck. Once she finished depressing the plunger and all of the formula was inside the other woman, Ivy pulled the syringe out and set it aside.

For a few moments, everything was quiet. Then Harleen winced, and her body tensed up. She relaxed for a brief second, but it wasn't long before she spasmed underneath the vines once, then again, and again. They were small at first, but each subsequent spasm got more violent, and soon Harleen's eyes rolled to the back of her head and she went into a full-blown seizure.

"Holly... Holly, it's okay, I'm right here," Ivy said, keeping the vines around the woman firm, and trying to keep her voice calm despite the thunderous beating of her heart, "I know it hurts, but just let it happen. It'll all be over soon. I'm right here, I'll be right here the whole time. I love you Holly... stay with me, you're going to be fine..."

She continued to say these soothing phrases as Harleen writhed in the bed, biting into the vine in her mouth hard enough to make juice flow out of it, and her skin transitioned from a light peach to a light green. After what felt like an eternity, the spasms grew less violent, and eventually died down entirely, leaving the new Harleen panting heavily. It was only when she was sure the transformation was complete that Ivy retracted the vines, and even then she couldn't help but be scared. What if this failed? What if her formula made Harleen braindead, or caused some other permanent damage? She wouldn't be able to live with herself if-

Harleen groaned, and her eyes fluttered open, now forest green like Ivy's. She looked up at her and smiled, and said, "Heya Miss Ivy... how do I look?"

Ivy broke out into a relieved smile, and helped her new girlfriend up out of the bed, guiding her to the full-length mirror in the room, "See for yourself."

On shaky feet, Harleen made her way to the mirror and looked herself over. She raised a hand to her green cheek, and whispered, "I'm... I'm beautiful. Like you. This is... this is the happiest day of my life!"

"Mine too," Ivy said, planting a kiss on her cheek.

Harleen giggled, then looked down at her chest, "Looks like ya gave me a little something extra too! Hold on..."

She squirmed out of Ivy's hold, then slipped the lab coat off of her shoulders to reveal that her dress, which had already been tight on her body, had been torn both in the chest and the butt when those areas grew during the transformation. Harley finished the job, tearing the red fabric off of her body completely, then undid the black bra that had been digging into her enhanced bust and let it drop to the ground.

Examining her new, curvier figure in the mirror, she said, "Ya didn't tell me I'd be getting an T and A upgrade to go with my new look."

"I didn't think that would happen," Ivy admitted, "It didn't happen to me... if you don't like it I'm sure we can get it reduced-"

"Hey, I ain't complaining," Harleen said with a cheeky grin, "It's gonna take some gettin' used to, but it's just more of me for ya to love!"

Turning to look at Ivy, she pouted and said, "Unless... Unless you prefer them smaller, Miss Ivy. If you do, just say the word and I'll get 'em back to their old size. Whatever makes you happy..."

Ivy chuckled and wrapped her arms around her, "You make me happy, Harleen. If you're happy with it, then so am I. You look damn sexy either way."

"Thanks, Red," Harleen said, "But... can ya not call me that again? Harleen ain't who I am... not anymore. I'm your Holly, now and forever."

"Yes, now and forever," Ivy repeated, "That reminds me..."

Ivy walked over to the windowsill and picked up a small holly plant she had been growing there. Taking it over to Holly, she said, "I grew this for you... consider it a present to celebrate your rebirth into the Green."

"Oh Miss Ivy, it's so cute!" Holly squealed, "Thank you!"

"If you think it's cute now, just hold still a second," Ivy said. She held the pot up to Holly's neck and, with a flick of her finger, the plant encircled her throat, pulling itself out of the soil and fastening itself into a collar. Once it did, a cluster of red berries grew out of the center.

Holly turned back to the mirror and let out another happy squeal, "Oh, it's beautiful! Thank you, Miss Ivy! I'm never takin' it off! Never!"

"Glad you like it," Ivy said, "Now, we should probably get you some new clothes. I had a few ideas of what your costume could be..."

"Forget that for now," Holly said, pulling down her black panties with one hand and taking off her glasses with the other, tossing them both aside, "All this transformin' and chokers and bigger boobs has got me fuckin' horny! I wanna finally fuck ya!"

"Holly, hold on, you need to re-" Ivy started to say, but she was interrupted when Holly smashed her lips against hers and began aggressively kissing her. Ivy gave in pretty quickly, kissing her back with a fiery passion.

After a solid minute of making out, Holly pulled back with a grin and said, "I've been wantin' to do that since I busted ya outta Arkham!"

"Same..." Ivy said. She then sighed and said, "Fuck it, fine, let's do it. But first, I think I deserve a little gratitude for everything I did for you. So get to it."

"Yes ma'am!" Holly said, and she dropped down to her knees. Grabbing the waistband of Ivy's pants, she yanked both them and her panties down in one smooth motion, exposing the slightly wet slit and red bush underneath. Holly licked her lips, savoring what was to come, then dove headfirst into Ivy's crotch and-

"I think you get the idea."

Inara pulled her finger back, and suddenly Ivy was back in the present, in her apartment with the kneeling Harley... no, Holly, looking up at her in worry and confusion. And much as she didn't want to admit it, after that realistic flashback she just experienced, the sight of Holly like this was a massive turn on.

"So that... that all happened?" Ivy said, looking to Inara.

"Yup!" Inara said, "You and her made love for like, a day straight after that! But I don't want you to experience that. If you want to see what Holly's like in the sack, you gotta do it for real."

Ivy gulped and looked down at this new woman before her. This was wrong, she knew it. Sure history had changed, but this was still Harley. Her girlfriend, warped beyond all recognition, changed on a whim by a hasty, poorly thought out wish to a mad sex genie in some fucked up monkey's paw scenario. She needed to find a way to fix it... right?

Almost as if sensing her internal conflict, Inara said, "If it makes you feel any better, this version of you never took advantage of or abused her in any way close to the level the Joker did. You've been a very caring and loving Mistress to your little Holly. Trust me, this is a good thing for both of you... so go ahead and enjoy it."

That... actually, that was a comfort to Ivy. Sure, she didn't mean to change Harley like this, especially without her permission, but at the same time... this was a Harley that never suffered at the hands of the Joker, one that actually got real love from the person she gave her entire heart and soul too. Was she really going to tear that away from her? Could she bring herself to put her life back in the Joker's hands, even if it was how things were 'supposed' to be?

And besides, even if she does end up fixing it... Harley and Holly were both her lover. She may not get a chance like this again. It might have been her by now very wet pussy talking, but would it really be so bad to have a bit of fun before changing her back? Would Harley understand? Maybe...?

"Miss Ivy?" Holly said, "What's wrong? Do ya need me to do somethin'?"

Goddammit Holly- Harley! Fuck, I can barely think straight as is. Do you really have to be so damn sexy right now?
